4
00:00:27.234 --> 00:00:28.284
Hi

5
00:00:28.284 --> 00:00:31.396
This is Lee Yongho, instructor of the shooting game development course

6
00:00:31.396 --> 00:00:33.646
In this chapter, we will learn about

7
00:00:33.646 --> 00:00:36.406
the first alpha version

8
00:00:36.406 --> 00:00:40.356
The first topic of learning is upgrading the Player

9
00:00:40.356 --> 00:00:42.911
Enemy, and Bullet to the alpha version

10
00:00:42.911 --> 00:00:44.811
Next, we will add explosion effects

11
00:00:44.811 --> 00:00:46.832
and learn how to control these effects

12
00:00:48.307 --> 00:00:51.707
Next, we will create a background that scrolls to the right

13
00:00:51.707 --> 00:00:54.000
We will learn how to play sounds next

14
00:00:54.528 --> 00:00:58.280
Upgrading the Player, Enemy, and Bullet to the alpha version

15
00:00:58.604 --> 00:01:03.000
Let's start by upgrading the Player to the alpha version

16
00:01:03.000 --> 00:01:06.200
Upgrading the Player to the alpha version means that

17
00:01:06.200 --> 00:01:10.000
previously, the player was created using a cube-based model

18
00:01:10.000 --> 00:01:14.450
Let's go through the process of upgrading the Player

19
00:01:14.450 --> 00:01:17.426
to the alpha version using actual assets and data

20
00:01:17.426 --> 00:01:19.426
we will need to use the Asset Store

21
00:01:19.426 --> 00:01:21.000
in Unity to do just that

22
00:01:21.000 --> 00:01:24.000
Let's open the Asset Store in Unity

23
00:01:24.000 --> 00:01:29.250
Clicking on Asset Store in the Window menu will open

24
00:01:29.250 --> 00:01:33.525
a web browser and take you to the Asset Store page

25
00:01:33.525 --> 00:01:36.975
In the Asset Store's search section

26
00:01:36.975 --> 00:01:41.000
you can find Awesome Cartoon Airplanes

27
00:01:41.000 --> 00:01:46.000
The Awesome Cartoon Airplanes asset will be like this

28
00:01:46.000 --> 00:01:52.000
Clicking on it will take you to the Awesome Cartoon Airplanes page

29
00:01:52.000 --> 00:01:53.640
Yes, you can download this asset

30
00:01:53.640 --> 00:01:57.614
Click the Add to My Assets button there

31
00:01:57.614 --> 00:02:01.014
then it will change like this, click Open in Unity

32
00:02:01.014 --> 00:02:06.436
Once you click the button Unity will open and the Package Manager will appear

33
00:02:06.436 --> 00:02:08.686
Then in Package Manager

34
00:02:08.686 --> 00:02:11.000
You can download the Awesome Cartoon Airplanes

35
00:02:11.000 --> 00:02:14.000
Let's click download

36
00:02:14.000 --> 00:02:17.000
After some time, the download will complete, very quick

37
00:02:17.000 --> 00:02:22.000
Now from here, click the Import button

38
00:02:22.000 --> 00:02:24.650
If you click import button

39
00:02:24.650 --> 00:02:28.644
You will get a new window called Import Unity Package

40
00:02:28.644 --> 00:02:32.094
From here, we can choose assets we want

41
00:02:32.094 --> 00:02:34.129
and then add to the project

42
00:02:34.129 --> 00:02:36.129
right now, all of these are selected

43
00:02:36.129 --> 00:02:38.879
Since we want everything, have these selected

44
00:02:38.879 --> 00:02:41.000
and click import

45
00:02:41.000 --> 00:02:43.574
Click

46
00:02:43.574 --> 00:02:47.674
Now, by importing these assets, they will be added to your Unity project

47
00:02:47.674 --> 00:02:50.000
and you can start using them in your scene and game

48
00:02:50.000 --> 00:02:52.450
If you see here in the Project window

49
00:02:52.450 --> 00:02:56.287
Here, can you see Awesome Cartoon?

50
00:02:56.287 --> 00:03:01.223
In this window, we can see the assets package

51
00:03:01.223 --> 00:03:03.792
we've downloaded has been added here

52
00:03:03.792 --> 00:03:06.317
Now you can close the package manager

53
00:03:06.317 --> 00:03:10.367
In here, if you look at Awesome Cartoon Airplanes folder

54
00:03:10.367 --> 00:03:14.584
The ones we will be using are in the folder called Airplanes

55
00:03:14.584 --> 00:03:18.000
This package is in the folder of Airplanes

56
00:03:18.000 --> 00:03:20.400
For the first player

57
00:03:20.400 --> 00:03:23.653
Let's use airplane number 1

58
00:03:23.653 --> 00:03:27.653
The question is, after selecting Airplane 1

59
00:03:27.653 --> 00:03:30.000
how would we actually implement it to player 1

60
00:03:30.000 --> 00:03:35.000
Let's select Airplane 1 and set it as a child of Airplanes and register it like this

61
00:03:35.000 --> 00:03:39.000
Them, you will get a player with a model like this

62
00:03:39.000 --> 00:03:47.000
After registering, grab the model and rotate it by 90 degrees

63
00:03:47.000 --> 00:03:53.000
You can change rotation value x to 180

64
00:03:53.000 --> 00:03:59.000
Airplane 1's size is 0.25mm

65
00:03:59.000 --> 00:04:06.000
Airplane 2 is also 0.25mm

66
00:04:06.000 --> 00:04:10.000
Then, it will be as big as our Player model before

67
00:04:10.000 --> 00:04:13.000
Like this, we've changed the size to 0.25mm

68
00:04:13.000 --> 00:04:16.000
You can actually do this all at once

69
00:04:16.000 --> 00:04:23.000
You can go to Scale property

70
00:04:23.000 --> 00:04:27.000
Mouse click on this icon here

71
00:04:27.000 --> 00:04:32.000
Now, the X button that previously had a line through it no longer has the slash

72
00:04:32.000 --> 00:04:36.000
If we set this up, we can change Airplanes' options all at once

73
00:04:36.000 --> 00:04:39.000
Let's put 1 in this box and then you will see everything change into 1

74
00:04:39.000 --> 00:04:43.000
If you put 0.2, others will also change to 0.2

75
00:04:43.000 --> 00:04:47.000
change values for scale option at once 0.2 or 0.25

76
00:04:47.000 --> 00:04:52.000
0.2 value gives you a good enough

77
00:04:52.000 --> 00:04:57.000
Next, what is responsible for the appearance of the player is

78
00:04:57.000 --> 00:05:00.000
If you select it as gameObject

79
00:05:00.000 --> 00:05:04.720
You can see this a white box implemented

80
00:05:04.720 --> 00:05:10.160
Let's remove this factor select it as Player and on the right side

81
00:05:10.160 --> 00:05:17.160
Here, the Mesh Renderer and the Cube, these are what directly handle the appearance of the player

82
00:05:17.160 --> 00:05:21.400
I want to make the cube box that is responsible for the appearance invisible

83
00:05:21.400 --> 00:05:24.799
Then, right-click on these two components and select the appropriate option

84
00:05:24.799 --> 00:05:28.920
If you select Remove Component, it will remove it from the screen

85
00:05:28.920 --> 00:05:33.680
Since the Cube is not actually needed, so for Mesh Filter, remove its component as well

86
00:05:33.680 --> 00:05:36.759
Cube Mesh Filter will also disappear from the screen

87
00:05:36.759 --> 00:05:40.209
The green outline around the object is currently visible though

88
00:05:40.209 --> 00:05:42.080
How do we remove it?

89
00:05:42.080 --> 00:05:47.520
This refers to the Box Collider

90
00:05:47.520 --> 00:05:50.200
The area of the Box Collider is what represents that part

91
00:05:50.200 --> 00:05:54.080
If I disable the checkbox, you'll notice that the color changes

92
00:05:54.080 --> 00:05:57.160
The Box Collider is exactly that part

93
00:05:57.160 --> 00:05:59.480
Now, the components responsible for the appearance are done

94
00:05:59.480 --> 00:06:03.680
If you look below, you'll see that the Gizmos option is checked in the game window

95
00:06:03.680 --> 00:06:07.320
To hide the Gizmos, you can uncheck this option

96
00:06:07.320 --> 00:06:13.162
By doing this, you've successfully updated the player’s appearance

97
00:06:13.162 --> 00:06:16.012
Now, let's press the play button

98
00:06:16.012 --> 00:06:18.839
Let's check if the player is correctly applied and appears as expected

99
00:06:18.839 --> 00:06:23.040
The propeller should be spinning, and the player should be able to move left, right, up, and down

100
00:06:23.040 --> 00:06:28.440
You should be able to see that the shooting and other features are working correctly

101
00:06:28.440 --> 00:06:31.490
Now, let's learn about upgrading

102
00:06:31.490 --> 00:06:34.120
the Enemy to the alpha version

103
00:06:34.120 --> 00:06:36.559
Let's go ahead and update the Enemy in the same way

104
00:06:36.559 --> 00:06:41.459
Without downloading anything, let's use Plane 2, 3, or 4

105
00:06:41.459 --> 00:06:43.959
to work on the Enemy update

106
00:06:43.959 --> 00:06:51.360
I will use the second one to update the Enemy's appearance

107
00:06:51.440 --> 00:06:54.640
The Enemy is not in the Hierarchy yet

108
00:06:54.640 --> 00:06:57.290
so even if we want, we can't

109
00:06:57.290 --> 00:06:58.959
drag and drop it right now

110
00:06:58.959 --> 00:07:00.709
So, where is the Enemy?

111
00:07:00.709 --> 00:07:04.519
The Enemy is not in Awesome Cartoon

112
00:07:04.519 --> 00:07:09.036
if you look below, you'll find it in the Prefabs folder we created earlier

113
00:07:09.036 --> 00:07:11.559
Enemy is right in there

114
00:07:11.559 --> 00:07:15.479
How do you make it a child of the one here?

115
00:07:15.479 --> 00:07:18.079
To enable editing for this prefab

116
00:07:18.079 --> 00:07:20.174
you can double click on it

117
00:07:20.174 --> 00:07:22.324
So when you double click it

118
00:07:22.324 --> 00:07:24.624
the Hierarchy and Scene windows

119
00:07:24.624 --> 00:07:27.080
will switch to edit mode

120
00:07:27.080 --> 00:07:31.630
In the Awesome Cartoon Planes folder

121
00:07:31.630 --> 00:07:33.039
there is a Prefabs folder as well

122
00:07:33.039 --> 00:07:39.000
Drag Plane 2 from the Prefabs folder and drop it into the Enemy object

123
00:07:39.000 --> 00:07:41.450
This is the result you get and same as before

124
00:07:41.450 --> 00:07:45.600
Now, let's remove the Mesh Filter and Mesh Renderer components

125
00:07:45.600 --> 00:07:49.000
from the Enemy object that we're currently using

126
00:07:49.000 --> 00:07:52.039
Right click on the component and then Remove Component

127
00:07:52.039 --> 00:07:54.839
Right click and then Remove Component for cube as well

128
00:07:54.839 --> 00:07:56.839
Like so

129
00:07:56.839 --> 00:08:00.479
Now, only Plane 2 will be visible

130
00:08:00.479 --> 00:08:02.800
Then, where should it be facing?

131
00:08:02.800 --> 00:08:05.100
This one shouldn't look up

132
00:08:05.100 --> 00:08:08.559
like the player, looking up

133
00:08:08.559 --> 00:08:11.240
Why is that so? this one is supposed to go down

134
00:08:11.240 --> 00:08:13.990
Therefore, it should be set to face

135
00:08:13.990 --> 00:08:16.401
the opposite direction of the player

136
00:08:16.401 --> 00:08:20.676
So, you can set the rotation values and X to -180

137
00:08:20.676 --> 00:08:23.759
and 180 for Y and Z

138
00:08:23.759 --> 00:08:26.559
For X, since it's just rotating by 180 degrees

139
00:08:26.559 --> 00:08:30.320
you can leave it as is

140
00:08:30.320 --> 00:08:32.839
You can proceed with this setup without any issues

141
00:08:32.839 --> 00:08:35.720
You should adjust the size to match the player’s size

142
00:08:35.720 --> 00:08:40.039
This button, which looks like a lock, allows you to change the size for all axes at once

143
00:08:40.039 --> 00:08:43.489
Click this button, then change the value of one axis to 0.2

144
00:08:43.489 --> 00:08:47.759
This will adjust the size of all axes uniformly

145
00:08:47.759 --> 00:08:52.440
Now, the entire setup for the Enemy is complete

146
00:08:52.440 --> 00:08:54.479
The wings of the Enemy are sticking out like this

147
00:08:54.479 --> 00:08:58.240
Even if everything is correct but you still want to remove it

148
00:08:58.240 --> 00:09:01.279
there's the Box Collider on the Enemy

149
00:09:01.279 --> 00:09:05.080
In the Box Collider, you can see options for Center and Size

150
00:09:05.080 --> 00:09:08.180
The center is about where to set

151
00:09:08.180 --> 00:09:11.720
the reference point based on this middle point

152
00:09:11.720 --> 00:09:15.679
If you change the X value of the Center

153
00:09:15.679 --> 00:09:19.679
the Box Collider will move horizontally, either to the left or right

154
00:09:19.679 --> 00:09:22.079
I'll leave the Center at 0

155
00:09:22.079 --> 00:09:25.279
and then I will try scaling it from the middle

156
00:09:25.279 --> 00:09:30.399
Let's try increasing the X value in the Size section to make it larger

157
00:09:30.399 --> 00:09:33.600
Let's switch to 2D mode to view the wings more clearly

158
00:09:33.600 --> 00:09:36.320
That way, you'll be able to see it more clearly

159
00:09:36.320 --> 00:09:40.519
Once it's roughly aligned like this, you can remove it as needed

160
00:09:40.519 --> 00:09:44.079
Since it will eventually move downwards, the bullet won't collide with the tail

161
00:09:44.079 --> 00:09:46.760
This should be enough to complete the setup

162
00:09:46.760 --> 00:09:50.060
So that if it collides here

163
00:09:50.060 --> 00:09:51.399
it will be destroyed

164
00:09:51.399 --> 00:09:53.279
Now we want to implement these settings

165
00:09:53.279 --> 00:09:54.720
How do we save this?

166
00:09:54.720 --> 00:09:58.959
If you look at the right edge of the Scene window

167
00:09:58.959 --> 00:10:02.480
you'll see that Auto Save is checked

168
00:10:02.480 --> 00:10:03.760
It means it saves automatically

169
00:10:03.760 --> 00:10:06.200
if this one is enabled

170
00:10:06.200 --> 00:10:08.679
Since we saved automatically through the Prefab

171
00:10:08.679 --> 00:10:11.440
all you need to do is click the Back button

172
00:10:11.440 --> 00:10:14.720
and it will return you to the original Scene view

173
00:10:14.720 --> 00:10:19.720
Since the Enemy has been properly updated in the Prefab

174
00:10:19.720 --> 00:10:24.399
when you click Play, you should be able to see

175
00:10:24.399 --> 00:10:26.480
Enemy's appearance in the game window

176
00:10:26.480 --> 00:10:31.839
It has been updated like this

177
00:10:31.839 --> 00:10:34.399
Since the Scene view looks strange

178
00:10:34.399 --> 00:10:38.160
I'll go back and set it to the Back

179
00:10:38.160 --> 00:10:41.040
Shall we place it so that the player is visible?

180
00:10:41.040 --> 00:10:45.760
I'll set it up like this and continue working

181
00:10:45.760 --> 00:10:47.960
So far, we've upgraded the Enemy

182
00:10:47.960 --> 00:10:51.359
to the alpha version

183
00:10:51.359 --> 00:10:52.920
Next, let's continue

184
00:10:52.920 --> 00:10:54.970
and upgrade the Bullet

185
00:10:54.970 --> 00:10:57.399
to the alpha version

186
00:10:57.399 --> 00:11:00.679
Let's search for Rockets

187
00:11:00.679 --> 00:11:10.079
Missiles and Bombs

188
00:11:10.079 --> 00:11:12.320
to find the assets we'll use here

189
00:11:12.320 --> 00:11:17.040
If you search for Rockets, Missiles

190
00:11:17.040 --> 00:11:20.920
you'll see it at the right end of the search results

191
00:11:20.920 --> 00:11:24.559
Then, just like before, you'll find a page where you can download this asset

192
00:11:24.559 --> 00:11:31.000
When you click Open in Unity, the Package Manager will open again

193
00:11:31.000 --> 00:11:33.000
In the Package Manager

194
00:11:33.000 --> 00:11:35.720
you can download the asset you want

195
00:11:35.720 --> 00:11:37.959
Let's click download

196
00:11:37.959 --> 00:11:40.359
Once it's done, it didn't take long

197
00:11:40.359 --> 00:11:43.000
Let's click that import button

198
00:11:43.000 --> 00:11:46.239
In the Import Unity Package, click Import button

199
00:11:46.239 --> 00:11:48.880
to bring every asset

200
00:11:48.880 --> 00:11:52.160
it worked and in here

201
00:11:52.160 --> 00:11:54.410
there's Orion Sky's asset

202
00:11:54.410 --> 00:11:56.160
Rockets, Missiles and Bombs

203
00:11:56.160 --> 00:11:57.410
Here, what we are going to use is

204
00:11:57.410 --> 00:12:00.480
the assets inside the Prefabs folder

205
00:12:00.480 --> 00:12:02.600
Which one we are going to use is

206
00:12:02.600 --> 00:12:06.640
To match Player's color, in the Yellow

207
00:12:06.640 --> 00:12:09.040
I'll use number 8 Rockets

208
00:12:09.040 --> 00:12:12.880
So how did we upgrade it to the alpha version?

209
00:12:12.880 --> 00:12:15.640
Just like the other one

210
00:12:15.640 --> 00:12:19.279
we need to go to Prefabs folder

211
00:12:19.279 --> 00:12:22.920
Click on the asset and go to the Prefabs folder

212
00:12:22.920 --> 00:12:25.359
where you’ll find the Bullet

213
00:12:25.359 --> 00:12:29.480
Double click the Bullet Prefab to open it

214
00:12:29.480 --> 00:12:31.399
Then you'll get edit mode

215
00:12:31.399 --> 00:12:34.760
The Yellow 8 that we selected earlier

216
00:12:34.760 --> 00:12:36.920
Let's drag and drop

217
00:12:36.920 --> 00:12:39.640
the Yellow 8 into the Bullet as a child

218
00:12:39.640 --> 00:12:42.799
Click Reset on the Transform to reset

219
00:12:42.799 --> 00:12:44.760
Then it appears

220
00:12:44.760 --> 00:12:48.880
It might appear in an odd position because it's placed incorrectly

221
00:12:48.880 --> 00:12:50.320
It's too big

222
00:12:50.320 --> 00:12:55.839
I will scale it down overall

223
00:12:55.839 --> 00:12:59.640
to about 0.15

224
00:12:59.640 --> 00:13:03.040
Reset the Bullet's Transform as well

225
00:13:03.040 --> 00:13:06.559
and then adjust it again as needed

226
00:13:06.559 --> 00:13:08.880
I'll click Reset on the Bullet's Transform

227
00:13:08.880 --> 00:13:10.880
to restore it to its original position

228
00:13:10.880 --> 00:13:15.000
and then the size value would still be 0.15

229
00:13:15.000 --> 00:13:18.200
this is the size of it

230
00:13:18.200 --> 00:13:20.000
all good so far

231
00:13:20.000 --> 00:13:23.640
Right now, the collider is way too big right now

232
00:13:23.640 --> 00:13:27.399
And also, it's centered in the wrong position

233
00:13:27.399 --> 00:13:29.040
there's unnecessary gap

234
00:13:29.040 --> 00:13:31.799
Therefore, we need to adjust

235
00:13:31.799 --> 00:13:33.919
the center point and for the collider

236
00:13:33.919 --> 00:13:35.280
to fit the actual shape

237
00:13:35.280 --> 00:13:39.359
First, let's remove the Cube that is used for the collider

238
00:13:39.359 --> 00:13:42.320
Right click on the Mesh Renderer and Mesh Filter

239
00:13:42.320 --> 00:13:46.359
then select Remove Component to delete them

240
00:13:46.359 --> 00:13:49.080
Then only the collider area will remain

241
00:13:49.080 --> 00:13:53.520
Next, let's reduce the X size of the Box Collider to better fit the Bullet

242
00:13:53.520 --> 00:13:56.039
Like so

243
00:13:56.039 --> 00:13:58.080
Let's try 0.5

244
00:13:58.080 --> 00:14:00.280
0.5

245
00:14:00.280 --> 00:14:03.760
0.45?

246
00:14:03.760 --> 00:14:05.760
0.45 fits the most perfectly

247
00:14:05.760 --> 00:14:09.719
Now, let's move the center upward appropriately

248
00:14:09.719 --> 00:14:11.840
For the collider's center value

249
00:14:11.880 --> 00:14:13.919
the Y value

250
00:14:13.919 --> 00:14:19.840
Let's increase the Y value by 0.07

251
00:14:19.840 --> 00:14:22.119
then we still have some gaps

252
00:14:22.119 --> 00:14:26.039
Let's change Y value to 0.9

253
00:14:26.039 --> 00:14:29.400
this should work fine

254
00:14:32.239 --> 00:14:34.239
So, by processing it like this

255
00:14:34.239 --> 00:14:35.739
when we select the Bullet

256
00:14:35.739 --> 00:14:38.640
it should be around this size

257
00:14:38.640 --> 00:14:40.479
Let's put 0.5 for size

258
00:14:40.479 --> 00:14:43.400
I'll make slight adjustments for the Bullet to be perfectly sized

259
00:14:43.400 --> 00:14:49.479
allowing it to fit with other objects as well

260
00:14:49.479 --> 00:14:54.840
Now, the Bullet's Prefab has been properly set up and is working correctly

261
00:14:54.840 --> 00:14:58.000
Now let's click Back button

262
00:14:58.000 --> 00:15:01.719
And see what we've got through a test

263
00:15:01.719 --> 00:15:05.760
Now, play

264
00:15:05.760 --> 00:15:09.880
You can confirm that the bullet is firing correctly now

265
00:15:09.880 --> 00:15:15.159
You can confirm that both the Enemy and Player

266
00:15:15.159 --> 00:15:18.239
have been updated to the actual data we want to use

267
00:15:18.239 --> 00:15:21.775
So, we've seen how to upgrade the Bullet

268
00:15:21.775 --> 00:15:23.358
to the alpha version up to this point

269
00:15:23.691 --> 00:15:27.473
Adding the explosion effect

270
00:15:29.159 --> 00:15:34.320
This time, when we play, there are a lot of parts that feel a bit boring

271
00:15:34.320 --> 00:15:37.479
So, let's add an explosion effect to make it more interesting

272
00:15:37.479 --> 00:15:40.919
Right now, what we’re working on feels a bit plain

273
00:15:40.919 --> 00:15:44.679
The bullets are firing and everything seems to be moving

274
00:15:44.679 --> 00:15:47.919
but it still feels lacking in excitement

275
00:15:47.919 --> 00:15:50.320
Exactly, to solve this, we will add an explosion effect

276
00:15:50.320 --> 00:15:53.359
to enhance the impact and make it feel more satisfying

277
00:15:53.359 --> 00:15:58.559
Let's use the Asset Store to find an explosion effect

278
00:15:58.559 --> 00:16:01.640
Go to asset store page

279
00:16:01.640 --> 00:16:11.760
Let's search for Cartoon FX Free here in the Asset Store

280
00:16:11.760 --> 00:16:17.080
Search Cartoon FX Free

281
00:16:17.080 --> 00:16:19.480
The one we will be using from here is

282
00:16:19.480 --> 00:16:21.799
This one right here

283
00:16:21.799 --> 00:16:27.799
the name is Cartoon FX Remaster Free

284
00:16:27.799 --> 00:16:29.880
Click this

285
00:16:29.880 --> 00:16:33.559
Click Open in Unity button

286
00:16:33.559 --> 00:16:42.400
The Package Manager will open, and the download will begin

287
00:16:42.400 --> 00:16:45.200
Once the download is complete, click the Import button

288
00:16:45.200 --> 00:16:49.239
to open the Import Unity Package window

289
00:16:49.239 --> 00:16:56.559
Let's Import it into Unity

290
00:16:56.559 --> 00:16:59.239
Once it's done

291
00:16:59.239 --> 00:17:02.919
it will be added to our Project window

292
00:17:02.919 --> 00:17:07.320
This time, there’s quite a bit of content to import

293
00:17:07.320 --> 00:17:10.239
A new window will appear like this as well

294
00:17:10.239 --> 00:17:14.479
I will hide this window and click to close it

295
00:17:14.479 --> 00:17:17.200
and also close the package manager window

296
00:17:17.200 --> 00:17:21.159
Now, in the Package Manager, the button

297
00:17:21.159 --> 00:17:24.200
for the downloaded asset will show JMO Assets

298
00:17:24.200 --> 00:17:26.200
In JMO Assets

299
00:17:26.200 --> 00:17:28.559
you'll find Demo Assets, and within that

300
00:17:28.559 --> 00:17:32.359
there is a demo scene file

301
00:17:32.359 --> 00:17:34.880
Do you see this Unity logo mark over here?

302
00:17:34.880 --> 00:17:38.039
There is Unity mark icon

303
00:17:38.039 --> 00:17:40.359
This is the Scene file

304
00:17:40.359 --> 00:17:42.440
Let's double click on the Scene file

305
00:17:42.440 --> 00:17:48.119
When you open it, you'll see this section that allows you to run

306
00:17:48.119 --> 00:17:52.760
Let's click on play button

307
00:17:52.760 --> 00:17:55.119
I'll increase the size of this window

308
00:17:55.119 --> 00:17:58.440
There is some kind of arrow and there are numbers from 1 to 31

309
00:17:58.440 --> 00:18:01.000
If I do a left mouse click

310
00:18:01.000 --> 00:18:03.880
We can see the explosion effect on click

311
00:18:03.880 --> 00:18:08.599
When you press the left or right arrow keys, it changes like this

312
00:18:08.599 --> 00:18:11.080
The effect changes

313
00:18:11.080 --> 00:18:15.559
There's also one with some flame

314
00:18:15.559 --> 00:18:18.000
effects like this again

315
00:18:18.000 --> 00:18:20.799
also like this

316
00:18:20.799 --> 00:18:24.919
or like this

317
00:18:24.919 --> 00:18:28.840
How should we make the plane to be destroyed

318
00:18:28.840 --> 00:18:30.919
Wow, there's even a huge explosion!

319
00:18:30.919 --> 00:18:34.719
You can select the ones you want from this list

320
00:18:34.719 --> 00:18:39.080
If you look, right now

321
00:18:39.080 --> 00:18:41.640
There's some kind of writing under the arrows and numbers

322
00:18:41.640 --> 00:18:45.599
If you want to see where these are activated

323
00:18:45.599 --> 00:18:47.599
you can open them like this to check

324
00:18:47.599 --> 00:18:52.039
In the demo script, you will see a list

325
00:18:52.039 --> 00:18:54.599
and one of them will be highlighted

326
00:18:54.599 --> 00:18:57.960
If I click here

327
00:18:57.960 --> 00:19:02.559
you'll notice that the items being used are

328
00:19:02.559 --> 00:19:03.760
all grayed out and deactivated

329
00:19:03.760 --> 00:19:07.039
You can see that it's only activated when I click, and that's when it becomes visible

330
00:19:07.039 --> 00:19:10.599
Right now, it is using

331
00:19:10.599 --> 00:19:12.599
CFX R3 Hit Light

332
00:19:12.599 --> 00:19:15.320
Alternatively, if you look at what is being displayed right now

333
00:19:15.320 --> 00:19:19.599
If you double-click on the object called Canvas and click on it

334
00:19:19.599 --> 00:19:23.200
The screen will shift to the view where the Canvas is located

335
00:19:23.200 --> 00:19:30.080
Then, I'll zoom in to take a closer look

336
00:19:30.080 --> 00:19:35.520
Here, where is it?

337
00:19:35.520 --> 00:19:42.760
Here is the name, CFX R3 Hit Light

338
00:19:42.760 --> 00:19:50.000
We just need to locate this part and work with it

339
00:19:50.000 --> 00:19:56.280
Then where is this thing, I said to look at demo script here

340
00:19:56.280 --> 00:19:58.919
The one that appears when you click here

341
00:19:58.919 --> 00:20:02.239
If you select that and right mouse click

342
00:20:02.239 --> 00:20:07.320
If you right-click and scroll down

343
00:20:07.320 --> 00:20:09.440
 you'll see the option called Prefab

344
00:20:09.440 --> 00:20:13.679
you can scroll down and enter it like this

345
00:20:13.679 --> 00:20:15.280
When you want to take one of these

346
00:20:18.000 --> 00:20:21.000
right click on it, since it is currently in Prefab state

347
00:20:21.000 --> 00:20:22.000
I will turn off the play button

348
00:20:22.000 --> 00:20:24.000
Then it is added as Prefab state

349
00:20:24.000 --> 00:20:26.000
After right mouse click

350
00:20:26.000 --> 00:20:28.000
and go to Prefab menu

351
00:20:28.000 --> 00:20:32.000
There is an option called Open Asset in Content

352
00:20:32.000 --> 00:20:36.000
Do you see it?

353
00:20:36.000 --> 00:20:39.000
Click Select Asset

354
00:20:39.000 --> 00:20:42.000
What happens? The link to

355
00:20:42.000 --> 00:20:44.000
where the window is appears

356
00:20:44.000 --> 00:20:46.000
It let us to jump there right away

357
00:20:46.000 --> 00:20:48.000
For others as well, mouse right click

358
00:20:48.000 --> 00:20:51.000
In Prefab, click Select Asset

359
00:20:51.000 --> 00:20:55.000
Then you can go to the location where the Asset is

360
00:20:55.000 --> 00:20:56.000
Do you see it?

361
00:20:56.000 --> 00:21:00.000
The one we will be using among these

362
00:21:00.000 --> 00:21:02.000
is the explosion effect

363
00:21:02.000 --> 00:21:04.000
So let's use Assets that are

364
00:21:04.000 --> 00:21:06.000
in the Explosion folder

365
00:21:06.000 --> 00:21:11.000
And this Fire effect

366
00:21:11.000 --> 00:21:14.000
or this other one

367
00:21:14.000 --> 00:21:17.000
so that we also have some smoke

368
00:21:17.000 --> 00:21:19.000
If you look, this one is the second one

369
00:21:19.000 --> 00:21:21.000
Let's see what it looks like when we actually play

370
00:21:21.000 --> 00:21:24.000
See how it's like

371
00:21:24.000 --> 00:21:26.000
I think this one is pretty good

372
00:21:26.000 --> 00:21:32.000
Compare between these two

373
00:21:32.000 --> 00:21:37.000
After explosion, even the screen shakes

374
00:21:37.000 --> 00:21:39.000
I like the first one

375
00:21:39.000 --> 00:21:41.000
and the second one is also good

376
00:21:41.000 --> 00:21:43.000
I will choose the one

377
00:21:43.000 --> 00:21:46.000
that has smoke after explosion

378
00:21:46.000 --> 00:21:47.000
How do we set the position?

379
00:21:47.000 --> 00:21:50.000
Right mouse click on Prefab

380
00:21:50.000 --> 00:21:52.000
find Select Asset

381
00:21:52.000 --> 00:21:54.000
And then it will find its location

382
00:21:54.000 --> 00:21:56.000
Let's use this one

383
00:21:56.000 --> 00:21:59.000
To enable the effect

384
00:21:59.000 --> 00:22:02.000
Let's adjust our script first

385
00:22:02.000 --> 00:22:05.000
Let's open default Scene file

386
00:22:05.000 --> 00:22:07.000
In the scene, Sample Scene

387
00:22:07.000 --> 00:22:10.000
This is what we've been working with

388
00:22:10.000 --> 00:22:12.000
Can't we use our Scene?

389
00:22:12.000 --> 00:22:13.000
We can change the name

390
00:22:13.000 --> 00:22:17.000
Or in the file, make a copy

391
00:22:17.000 --> 00:22:20.000
by clicking Save As

392
00:22:20.000 --> 00:22:21.000
in order to make use of it

393
00:22:21.000 --> 00:22:23.000
However, there are rules to this

394
00:22:23.000 --> 00:22:24.000
What kind of a rule?

395
00:22:24.000 --> 00:22:27.000
This one must stay in the Asset Folder

396
00:22:27.000 --> 00:22:29.000
It shouldn't stay outside the folder

397
00:22:29.000 --> 00:22:31.000
Remember, that's the rule

398
00:22:31.000 --> 00:22:34.000
You have to save this Scene file inside the Asset Folder

399
00:22:34.000 --> 00:22:35.000
If we were to save it in this Scene

400
00:22:35.000 --> 00:22:38.000
as Shooting Scene

401
00:22:38.000 --> 00:22:42.000
Save it as Shooting Scene

402
00:22:42.000 --> 00:22:44.000
You have to save it here

403
00:22:44.000 --> 00:22:47.000
You shouldn't save it outside the Asset Folder

404
00:22:47.000 --> 00:22:48.000
Save

405
00:22:48.000 --> 00:22:50.000
Then we can see that there's a new scene called Shooting Scene

406
00:22:50.000 --> 00:22:53.000
and if you double click

407
00:22:53.000 --> 00:22:55.000
in the Hierarchy

408
00:22:55.000 --> 00:22:58.000
Do you see a Scene file named Sample Scene?

409
00:22:58.000 --> 00:23:01.000
When Shooting Scene opens

410
00:23:01.000 --> 00:23:03.000
you’ll see that the window switches to Shooting Scene

411
00:23:03.000 --> 00:23:06.000
or you can open multiple scenes when working

412
00:23:06.000 --> 00:23:08.000
just like here

413
00:23:08.000 --> 00:23:11.000
if you drag and drop the Sample Scene here

414
00:23:11.000 --> 00:23:13.000
you can see the structure of Unity

415
00:23:13.000 --> 00:23:16.000
where two scenes open at the same time

416
00:23:16.000 --> 00:23:17.000
do you see it?

417
00:23:17.000 --> 00:23:19.000
you can have two Scenes

418
00:23:19.000 --> 00:23:20.000
at the same time

419
00:23:20.000 --> 00:23:24.000
When I made a change up here, the change follows down there as well

420
00:23:24.000 --> 00:23:28.000
Like this, you can have two scenes opened up

421
00:23:28.000 --> 00:23:30.000
If you want to remove one

422
00:23:30.000 --> 00:23:31.000
you can right mouse click on it

423
00:23:31.000 --> 00:23:32.000
How?

424
00:23:32.000 --> 00:23:35.000
Select Remove Scene

425
00:23:35.000 --> 00:23:38.000
Unload Scene is to only disable it

426
00:23:38.000 --> 00:23:39.000
How again?

427
00:23:39.000 --> 00:23:40.000
If you click Remove Scene

428
00:23:40.000 --> 00:23:43.000
you are removing the registered file

429
00:23:43.000 --> 00:23:45.000
It won't remove any original data

430
00:23:45.000 --> 00:23:48.000
so that's that

431
00:23:48.000 --> 00:23:50.000
So, we are working

432
00:23:50.000 --> 00:23:52.000
in the Shooting Scene

433
00:23:52.000 --> 00:23:57.000
Where do we use the explosion effect then?

434
00:23:57.000 --> 00:24:05.000
In the Script window, let's open Enemy Script

435
00:24:05.000 --> 00:24:09.000
Then, we will have the effect process here

436
00:24:09.000 --> 00:24:11.000
the reason we do that here is simple

437
00:24:11.000 --> 00:24:15.000
Think about where the explosion effect should occur

438
00:24:15.000 --> 00:24:20.000
Let's check this diagram

439
00:24:20.000 --> 00:24:23.000
The collision we implemented

440
00:24:23.000 --> 00:24:25.000
with Enemy, Player or Bullet

441
00:24:25.000 --> 00:24:28.000
When colliding, the way they collide is

442
00:24:28.000 --> 00:24:31.000
that Player and Enemy were able to collide

443
00:24:31.000 --> 00:24:34.000
And one more, Enemy and Bullet

444
00:24:34.000 --> 00:24:37.000
were made possible to collide each other

445
00:24:37.000 --> 00:24:41.000
and Player and Bullet weren't allowed to collide each other

446
00:24:41.000 --> 00:24:43.000
and between Enemies as well

447
00:24:43.000 --> 00:24:46.000
We made these rules at a default setting level

448
00:24:46.000 --> 00:24:51.000
So, in a way, if Player and Bullet cannot collide

449
00:24:51.000 --> 00:24:55.000
who would be the common denominator between Player and Enemy?

450
00:24:55.000 --> 00:24:58.000
Since the denominator comes down to Enemy

451
00:24:58.000 --> 00:25:00.000
So if to say Enemies go Kamikaze on us

452
00:25:00.000 --> 00:25:05.000
It can eliminate both the player and the bullets

453
00:25:05.000 --> 00:25:07.000
So, how is the script set up?

454
00:25:07.000 --> 00:25:11.000
collision handling is being processed in the Enemy script

455
00:25:11.000 --> 00:25:14.000
Then, if the Enemy explodes when it collides

456
00:25:14.000 --> 00:25:17.000
How about if both are eliminated

457
00:25:17.000 --> 00:25:21.000
and an explosion effect is triggered when it collides?

458
00:25:21.000 --> 00:25:25.000
We can display it as if everyone exploded

459
00:25:25.000 --> 00:25:28.000
So, I will implement adding an explosion effect

460
00:25:28.000 --> 00:25:33.000
In the Enemy script when it collides

461
00:25:33.000 --> 00:25:35.000
The part we're referring to is located at the bottom

462
00:25:35.000 --> 00:25:42.000
the OnCollisionEnter in the Enemy.cs

463
00:25:42.000 --> 00:25:46.000
When Enemy collides with other object

464
00:25:46.000 --> 00:25:50.000
what do we want to do?

465
00:25:50.000 --> 00:25:55.000
We want to have explosion effect

466
00:25:55.000 --> 00:26:00.000
want to trigger the explosion effect to be exact

467
00:26:00.000 --> 00:26:05.000
Then where do we make Bullet?

468
00:26:05.000 --> 00:26:08.000
we make it from the bulletFactory

469
00:26:08.000 --> 00:26:10.000
And then where do we make Enemy?

470
00:26:10.000 --> 00:26:11.000
Also from enemyFactory

471
00:26:11.000 --> 00:26:14.000
Same should go with explosion, where?

472
00:26:14.000 --> 00:26:16.000
Should be made from

473
00:26:16.000 --> 00:26:19.000
Let's do it this way

474
00:26:19.000 --> 00:26:22.000
Therefore, this one is in need of certain property

475
00:26:22.000 --> 00:26:26.000
I will add the properties needed for the explosion at the top

476
00:26:26.000 --> 00:26:32.000
At the top here, we need a explosionFactory

477
00:26:32.000 --> 00:26:42.000
Write Public GameObject then explosionFactory

478
00:26:42.000 --> 00:26:46.000
explosionFactory

479
00:26:46.000 --> 00:26:52.000
So we've just declared an explosionFactory

480
00:26:52.000 --> 00:26:56.000
If you go to Unity

481
00:26:56.000 --> 00:27:00.000
Let's take a look at Enemy Prefab

482
00:27:00.000 --> 00:27:03.000
If you go to the Inspector window on the right

483
00:27:03.000 --> 00:27:08.000
The explosionFactory is exposed in the Enemy script

484
00:27:08.000 --> 00:27:11.000
To this part, drag and drop

485
00:27:11.000 --> 00:27:18.000
Explosion part from CFXS Prefab in JMOSS

486
00:27:18.000 --> 00:27:23.000
to CFXS Prefab, drag Explosion part

487
00:27:23.000 --> 00:27:30.000
and drop into explosionFactory

488
00:27:30.000 --> 00:27:32.000
Then to the Asset we are going to utilize

489
00:27:32.000 --> 00:27:37.000
will have explosionFactory registered

490
00:27:37.000 --> 00:27:42.000
Since it's registered in here

491
00:27:42.000 --> 00:27:47.000

Let's go down and try to trigger the explosion effect

492
00:27:47.000 --> 00:27:49.000
Triggering explosion effect means

493
00:27:49.000 --> 00:27:51.650
Eventually means, from bulletFactory or

494
00:27:51.650 --> 00:27:55.000
explosionFactory, making explosion

495
00:27:55.000 --> 00:27:57.000
Then, how do we make it happen

496
00:27:57.000 --> 00:28:00.000
start with Instantiate

497
00:28:00.000 --> 00:28:02.800
explosionFactory

498
00:28:02.800 --> 00:28:07.000
put explosionFactory inside

499
00:28:07.000 --> 00:28:11.000
if you do this, making explosion is done so far

500
00:28:11.000 --> 00:28:14.000
then where is this?

501
00:28:14.000 --> 00:28:16.000
It is placed at a default location

502
00:28:16.000 --> 00:28:19.000
we have to set up its location, too

503
00:28:19.000 --> 00:28:21.000
Where is this effect supposed to occur?

504
00:28:21.000 --> 00:28:23.000
It has to occur where Enemy is

505
00:28:23.000 --> 00:28:30.000
Therefore, start with GameObject explosion

506
00:28:30.000 --> 00:28:33.000
make a variable, that saves Instance

507
00:28:33.000 --> 00:28:39.000
and in the next line, who has the location of explosion?

508
00:28:39.000 --> 00:28:40.950
transform dot position

509
00:28:40.950 --> 00:28:43.277
In what location should we set it to?

510
00:28:43.277 --> 00:28:45.077
Enemy will be the one exploding

511
00:28:45.077 --> 00:28:49.000
Having the effect at Enemy's location will do

512
00:28:49.000 --> 00:28:51.000
So, transform dot position

513
00:28:51.000 --> 00:28:54.000
Right now, we are at Enemy

514
00:28:54.000 --> 00:28:56.000
we are on a Enemy script

515
00:28:56.000 --> 00:28:58.500
So since this is Enemy's transform position

516
00:28:58.500 --> 00:29:01.000
The location we want is its own location

517
00:29:01.000 --> 00:29:04.000
I have set it up so that the explosion effect occurs

518
00:29:04.000 --> 00:29:06.000
at the Enemy's location

519
00:29:06.000 --> 00:29:09.000
Let's save and comeback to Unity

520
00:29:09.000 --> 00:29:13.000
Play

521
00:29:13.000 --> 00:29:16.000
Then it moves like this

522
00:29:16.000 --> 00:29:19.000
How's this?

523
00:29:19.000 --> 00:29:23.935
Even the screen shakes

524
00:29:23.935 --> 00:29:28.000
explosion effect occurring

525
00:29:28.000 --> 00:29:30.000
How was screen shake effect created?

526
00:29:30.000 --> 00:29:35.000
What that means is, in this explosion effect part, there is this script

527
00:29:35.000 --> 00:29:38.800
If you look below this script, in the script called CFXR Effect

528
00:29:38.800 --> 00:29:42.650
the very bottom, it’s being distributed

529
00:29:42.650 --> 00:29:45.772
the effect is being processed

530
00:29:45.772 --> 00:29:48.000
there is an option called Camera Shake

531
00:29:48.000 --> 00:29:50.017
Inside this, it takes the Main Camera

532
00:29:50.017 --> 00:29:52.567
handles everything on its own

533
00:29:52.567 --> 00:29:54.683
and then updates the content

534
00:29:54.683 --> 00:29:56.000
If we don't want any shaking effect

535
00:29:56.000 --> 00:30:00.723
we simply can disable Camera Shake

536
00:30:00.723 --> 00:30:03.705
After disabling, let's play to see what happens

537
00:30:09.320 --> 00:30:12.020
Bang Bang Bang, how is it like?

538
00:30:12.020 --> 00:30:15.520
there's only explosion but without camera shaking

539
00:30:15.520 --> 00:30:19.351
you can see that it worked, it's done

540
00:30:19.351 --> 00:30:23.151
We will proceed with this setting

541
00:30:23.151 --> 00:30:26.151
Like so, we disabled

542
00:30:26.151 --> 00:30:29.120
cameraShake

543
00:30:29.120 --> 00:30:31.820
By doing this, we have applied the explosion effect scene

544
00:30:31.820 --> 00:30:34.523
in the alpha version so far

545
00:30:34.820 --> 00:30:38.751
Adding Background Playing Sound Effects

546
00:30:40.208 --> 00:30:43.058
Next order of business is to add background image

547
00:30:43.058 --> 00:30:45.200
The scene feels a bit dull having no background

548
00:30:45.200 --> 00:30:49.100
The level of completion for this content is still not high at the moment

549
00:30:49.100 --> 00:30:52.080
So, we will add a background this time to enhance it

550
00:30:52.080 --> 00:30:54.480
If you look at things like bottles

551
00:30:54.480 --> 00:30:59.599
you can often see tape with advertising slogans on them

552
00:30:59.599 --> 00:31:02.499
These things are wrapped around the back like this

553
00:31:02.499 --> 00:31:05.800
For example, it's wrapping a plastic sheet around it

554
00:31:05.800 --> 00:31:08.800
And there are some writings in there

555
00:31:08.800 --> 00:31:15.750
like the name of the drink like New Drink for example

556
00:31:15.750 --> 00:31:19.800
How about we rotate the bottle

557
00:31:19.800 --> 00:31:21.400
then what happens?

558
00:31:21.400 --> 00:31:27.296
this sentence will be disappearing little by little

559
00:31:27.296 --> 00:31:28.663
it will be on the other side

560
00:31:28.663 --> 00:31:32.519
and a new sentence or content will be show up

561
00:31:32.519 --> 00:31:33.969
because we rotated it

562
00:31:33.969 --> 00:31:36.219
In other words, when we rotate a single sheet

563
00:31:36.219 --> 00:31:38.839
where should we focus our view?

564
00:31:38.839 --> 00:31:41.189
We should focus our view right on this part

565
00:31:41.189 --> 00:31:45.800
Let's assume we fix our screen only on this part

566
00:31:45.800 --> 00:31:46.850
How is it like then?

567
00:31:46.850 --> 00:31:49.150
It might look like something is continuously moving, right?

568
00:31:49.150 --> 00:31:51.900
You can script the screen in this way

569
00:31:51.900 --> 00:31:53.279
with one sheet

570
00:31:53.279 --> 00:31:55.929
Since we've been using Asset Store

571
00:31:55.929 --> 00:31:58.160
might as well use it for this one as well

572
00:31:58.160 --> 00:32:01.010
The most common and straightforward option here would be a space image

573
00:32:01.010 --> 00:32:05.985
Space Star Field Backgrounds

574
00:32:07.839 --> 00:32:11.139
When you search like this

575
00:32:11.139 --> 00:32:15.320
You will find a file called Space Star Field Backgrounds

576
00:32:15.320 --> 00:32:18.633
Among them, let's use the one

577
00:32:18.633 --> 00:32:20.520
with space image should be easier than others

578
00:32:20.520 --> 00:32:24.870
Since  this one has white dots in the black background

579
00:32:24.870 --> 00:32:28.440
When it's wrapped, it probably won't be very noticeable

580
00:32:28.440 --> 00:32:30.590
Let's select this one

581
00:32:30.590 --> 00:32:34.130
The price is FREE

582
00:32:34.130 --> 00:32:36.730
This is the space image and I will use this one

583
00:32:36.730 --> 00:32:37.997
Open in Unity

584
00:32:40.189 --> 00:32:44.683
And download the image

585
00:32:44.683 --> 00:32:49.233
Once the download is complete, click the Import button

586
00:32:49.233 --> 00:32:54.160
and then click Import to add it to the project

587
00:32:54.160 --> 00:33:00.090
After adding it, the file we just downloaded

588
00:33:00.090 --> 00:33:02.000
should be under the StarfieldMaterials folder

589
00:33:02.000 --> 00:33:05.600
If you look at this texture image

590
00:33:05.600 --> 00:33:09.000
Here, you can see that there are

591
00:33:09.000 --> 00:33:10.919
a lot of images we want to use

592
00:33:10.919 --> 00:33:14.520
Right?

593
00:33:14.520 --> 00:33:18.420
Click the plus button to create a new folder

594
00:33:18.420 --> 00:33:24.440
and then place the Materials in that folder

595
00:33:24.440 --> 00:33:27.740
Create a Materials folder

596
00:33:27.740 --> 00:33:29.897
and then create a new Material inside that folder

597
00:33:29.897 --> 00:33:33.597
In the Project window, click the plus button in the Materials folder

598
00:33:33.597 --> 00:33:36.839
and you'll see the Material option in the center

599
00:33:36.839 --> 00:33:39.389
Create it there

600
00:33:39.389 --> 00:33:46.160
Let's name it Mat Background and add it

601
00:33:46.160 --> 00:33:50.760
This material has been created

602
00:33:50.760 --> 00:33:53.360
and now let's add the material

603
00:33:53.360 --> 00:33:54.399
we want to use to it

604
00:33:54.399 --> 00:33:56.499
Let's add the value to the Albedo property

605
00:33:56.499 --> 00:34:00.149
If you look in the StarfieldMaterial

606
00:34:00.149 --> 00:34:03.399
you'll see an option called SingleNeb

607
00:34:03.399 --> 00:34:06.799
We will use something more noticeable

608
00:34:06.799 --> 00:34:10.999
like option 7 from here

609
00:34:10.999 --> 00:34:14.679
In the Materials folder, select it again

610
00:34:14.679 --> 00:34:20.479
Then, for the Albedo section, click and hold on SingleNeb

611
00:34:20.479 --> 00:34:23.507
and drag option 7 into the Albedo slot

612
00:34:23.507 --> 00:34:28.445
By holding it there, it will be registered properly

613
00:34:28.445 --> 00:34:32.679
Now, you can see the preview like this

614
00:34:32.679 --> 00:34:36.129
If you don't want it to be displayed as a circle

615
00:34:36.129 --> 00:34:37.579
we can change that

616
00:34:37.579 --> 00:34:39.429
If you click different options

617
00:34:39.429 --> 00:34:42.102
This part right here

618
00:34:42.102 --> 00:34:45.102
If you click this, the shape of the object

619
00:34:45.102 --> 00:34:48.728
This is cylinder, tube

620
00:34:48.728 --> 00:34:51.078
and then square plain shape

621
00:34:51.078 --> 00:34:52.985
It's like this

622
00:34:55.513 --> 00:34:57.913
Sphere, cube and so on

623
00:34:57.913 --> 00:35:00.839
we can switch between different shapes

624
00:35:00.839 --> 00:35:03.539
Like this

625
00:35:03.539 --> 00:35:06.239
Since we are having square background

626
00:35:06.239 --> 00:35:08.436
Let's use this shape and see what it will look like

627
00:35:11.879 --> 00:35:15.607
With this setup, let's go ahead and create

628
00:35:15.607 --> 00:35:18.408
the background where it will be applied

629
00:35:18.408 --> 00:35:23.008
In the Hierarchy, click the plus button

630
00:35:23.008 --> 00:35:28.000
then go to 3D Object and add a Quad

631
00:35:28.000 --> 00:35:32.000
Next, let's rename it to Background

632
00:35:34.119 --> 00:35:37.369
The size is very small

633
00:35:37.369 --> 00:35:40.919
So let's enlarge it a bit

634
00:35:40.919 --> 00:35:43.669
To make it fill the screen more

635
00:35:43.669 --> 00:35:47.266
Let's zoom in

636
00:35:47.266 --> 00:35:49.866
As you stretch it horizontally

637
00:35:49.866 --> 00:35:52.716
Take a look at it from the Game view

638
00:35:52.716 --> 00:35:54.919
and you'll see it start to fill the screen

639
00:35:54.919 --> 00:35:57.840
You can adjust it to fit reasonably well like this

640
00:35:57.840 --> 00:36:02.160
Set the value to around 14, and 14 for X as well

641
00:36:02.160 --> 00:36:06.800
Then, stretch the Y value to adjust it accordingly

642
00:36:06.800 --> 00:36:09.959
Set the Y value to around 20

643
00:36:09.959 --> 00:36:12.727
Now, when you look at it from the Main Camera's perspective

644
00:36:15.559 --> 00:36:18.559
you can see that it fills the screen

645
00:36:18.559 --> 00:36:21.509
You can confirm that it fits perfectly

646
00:36:21.509 --> 00:36:24.599
inside the white outline of the Main Camera

647
00:36:24.599 --> 00:36:29.324
You can see that it fits perfectly like this

648
00:36:29.324 --> 00:36:32.474
Now, let's assign the material

649
00:36:32.474 --> 00:36:34.199
we want to use to this

650
00:36:34.199 --> 00:36:37.349
To assign the material, you can either

651
00:36:37.349 --> 00:36:40.449
drag and drop it into the

652
00:36:40.449 --> 00:36:42.160
Material section of the Mesh Renderer on the background

653
00:36:42.160 --> 00:36:44.460
Alternatively, you can find the Mat Background

654
00:36:44.460 --> 00:36:46.639
in the Materials folder that we've created and assign it from there

655
00:36:46.639 --> 00:36:49.733
You can also drag and drop it like this to assign it

656
00:36:49.733 --> 00:36:51.833
Alternatively, you can place it here

657
00:36:51.833 --> 00:36:53.760
or anywhere else you'd like

658
00:36:53.760 --> 00:36:56.260
If you place it conveniently, it will be applied like this

659
00:36:56.260 --> 00:37:01.213
This means the background has been successfully applied

660
00:37:01.213 --> 00:37:06.077
However, when we play

661
00:37:10.760 --> 00:37:13.510
even though the background is added

662
00:37:13.510 --> 00:37:15.060
what happens? It disappears, why?

663
00:37:15.060 --> 00:37:17.600
It disappears because it collides with the Enemy

664
00:37:17.600 --> 00:37:20.600
The reason this happens is because

665
00:37:20.600 --> 00:37:22.439
Let me pull the player a bit closer

666
00:37:22.439 --> 00:37:25.939
If you look at it this way, Let me slightly rotate it to the side

667
00:37:25.939 --> 00:37:31.014
Then, you can see that the Background is overlapping halfway

668
00:37:33.664 --> 00:37:36.714
So, they are set to collide with each other when they appear

669
00:37:36.714 --> 00:37:39.314
So, the Enemy is colliding with the Background

670
00:37:39.314 --> 00:37:41.200
That's why we have these problems

671
00:37:41.200 --> 00:37:43.700
So, should we disable the collider then?

672
00:37:43.700 --> 00:37:47.680
It would be fine, but the reason I'm working

673
00:37:47.680 --> 00:37:49.805
in the regular 3D mode

674
00:37:49.805 --> 00:37:52.155
instead of the 2D mode is

675
00:37:52.155 --> 00:37:54.239
It's exactly for this convenience

676
00:37:54.239 --> 00:37:55.607
For this convenience, how do we do it?

677
00:37:55.607 --> 00:37:59.107
Simply select the background

678
00:37:59.107 --> 00:38:03.120
and then just move it over here

679
00:38:03.120 --> 00:38:07.320
So, how does it look? The background and the player

680
00:38:07.320 --> 00:38:10.994
no longer overlap as we see it now

681
00:38:10.994 --> 00:38:15.344
So, even when the Enemy appears, it will no longer overlap in this area

682
00:38:15.344 --> 00:38:18.239
You can simply push it like this

683
00:38:18.239 --> 00:38:22.668
Now, if you place it like this and play again

684
00:38:22.680 --> 00:38:26.962
the background will remain visible, and the Enemy will appear

685
00:38:32.688 --> 00:38:36.500
Like so, we finally have a background

686
00:38:39.361 --> 00:38:44.919
So, the size and location of the Background have been fully applied

687
00:38:44.919 --> 00:38:47.169
But since this Background is static

688
00:38:47.169 --> 00:38:50.199
it seems like there's a lack of speed or movement

689
00:38:50.199 --> 00:38:53.649
So, if you select the Background and go to the right

690
00:38:53.649 --> 00:38:56.639
you can preview the material

691
00:38:56.639 --> 00:38:58.739
that we're using in here

692
00:38:58.739 --> 00:39:01.240
You can edit the Material here

693
00:39:01.240 --> 00:39:03.290
or you can also modify it

694
00:39:03.290 --> 00:39:05.520
in the material settings

695
00:39:05.520 --> 00:39:07.770
There's an option called Offset

696
00:39:07.770 --> 00:39:10.220
Let me change the Y value

697
00:39:10.220 --> 00:39:11.820
When you look at the screen

698
00:39:11.820 --> 00:39:14.880
Please check how the current screen is set up

699
00:39:14.880 --> 00:39:19.180
You can see that the screen moves when I change the Y value, right?

700
00:39:19.180 --> 00:39:21.679
It looks like the plane is constantly moving, right?

701
00:39:21.679 --> 00:39:23.579
You can create this kind of effect

702
00:39:23.579 --> 00:39:25.579
So, if you continuously

703
00:39:25.579 --> 00:39:29.160
change the Offset in the code in real time

704
00:39:29.160 --> 00:39:33.010
this part will animate, creating the feeling

705
00:39:33.010 --> 00:39:35.160
that the player is moving

706
00:39:35.160 --> 00:39:37.326
So, let's use a script to adjust

707
00:39:37.326 --> 00:39:40.119
the Offset value for it

708
00:39:40.119 --> 00:39:46.848
In the Scripts folder, click + and C#

709
00:39:46.848 --> 00:39:52.059
Let's name it Background

710
00:39:52.059 --> 00:39:53.689
As we have a background

711
00:39:53.689 --> 00:39:56.439
Let's drag and drop the script

712
00:39:56.439 --> 00:39:58.360
onto the Background GameObject

713
00:39:58.360 --> 00:40:01.960
Now, the Background has been added here

714
00:40:01.960 --> 00:40:05.231
double click

715
00:40:05.231 --> 00:40:07.381
Go to Background

716
00:40:07.381 --> 00:40:11.181
Since we need to change the Offset

717
00:40:11.181 --> 00:40:14.080
in the material it's using

718
00:40:14.080 --> 00:40:18.830
what we want to do here is scroll the background

719
00:40:18.830 --> 00:40:22.473
At that time, the necessary property is

720
00:40:22.473 --> 00:40:27.123
the Offset in the material, and it needs to be modified

721
00:40:27.123 --> 00:40:29.839
in the Material it is using, so what does it need?

722
00:40:29.839 --> 00:40:31.739
Material is the one

723
00:40:31.739 --> 00:40:34.488
Then how fast it will scroll down

724
00:40:34.488 --> 00:40:37.600
is another question

725
00:40:37.600 --> 00:40:40.100
We need the scroll speed

726
00:40:40.100 --> 00:40:42.919
We can achieve these utilizing two properties

727
00:40:42.919 --> 00:40:47.741
Let's add the material

728
00:40:47.741 --> 00:40:51.781
and then name it bgMaterial

729
00:40:51.781 --> 00:40:54.120
I will name it like this

730
00:40:54.120 --> 00:40:55.720
Background Material

731
00:40:55.720 --> 00:40:59.440
Next, let's allow the designer to modify the scroll speed by making it public

732
00:40:59.440 --> 00:41:05.720
public float and scrollSpeed 
We'll add this to it

733
00:41:05.720 --> 00:41:10.120
Let's set the scroll speed to around 0.2 for this

734
00:41:10.120 --> 00:41:13.020
then where do we get this Material from?

735
00:41:13.020 --> 00:41:15.760
Instead of continuously checking during runtime

736
00:41:15.760 --> 00:41:19.799
we'll make it find it once when the object is created and assign it here

737
00:41:19.840 --> 00:41:26.240
So, we need to first get the Mesh Renderer

738
00:41:26.240 --> 00:41:29.540
component attached to this object, because

739
00:41:29.540 --> 00:41:32.680
What does Mesh Renderer have on this background?

740
00:41:32.680 --> 00:41:34.780
The reason is that it holds Material

741
00:41:34.780 --> 00:41:37.119
Mesh Renderer component has Material

742
00:41:37.119 --> 00:41:40.680
So first, we need to get Mesh Renderer component

743
00:41:40.680 --> 00:41:42.525
The method we could use here is

744
00:41:42.525 --> 00:41:45.040
GetCoponent function

745
00:41:45.040 --> 00:41:48.759
You just need to add the name of the component you want to retrieve here

746
00:41:48.759 --> 00:41:52.680
So add in Mesh Renderer here

747
00:41:52.680 --> 00:41:55.440
Then the function will get Mesh Renderer

748
00:41:55.440 --> 00:41:58.390
Then we get this, which one do we render?

749
00:41:58.390 --> 00:42:00.400
It would be Material

750
00:42:00.400 --> 00:42:05.400
We can dynamically get the material we want to use

751
00:42:05.400 --> 00:42:09.519
Now, we just need to scroll the Offset

752
00:42:09.519 --> 00:42:12.839
Then, we want to gradually increase the Offset value now

753
00:42:12.839 --> 00:42:17.000
and for this, we will be utilizing the formula for uniform motion

754
00:42:17.040 --> 00:42:19.080
How about the direction? How does uniform motion work?

755
00:42:19.080 --> 00:42:22.959
P = P0 + vt

756
00:42:22.959 --> 00:42:26.639
v means velocity that we need

757
00:42:26.639 --> 00:42:27.919
It's the vector

758
00:42:27.919 --> 00:42:31.219
To offset with this formula

759
00:42:31.219 --> 00:42:35.304
First, we need direction

760
00:42:35.304 --> 00:42:36.919
What's the second?

761
00:42:36.919 --> 00:42:37.807
simply make it move

762
00:42:37.807 --> 00:42:39.680
Scroll eventually means to move

763
00:42:39.680 --> 00:42:43.879
Because we scroll, move it in a given direction

764
00:42:43.879 --> 00:42:46.080
So, let's state the direction

765
00:42:46.160 --> 00:42:51.160
If you look at vector, there are only X and Y value

766
00:42:51.160 --> 00:42:53.199
For offset, right?

767
00:42:53.199 --> 00:42:57.320
Since this texture is an image, the image has no depth

768
00:42:57.320 --> 00:42:59.820
Of course there are 3D textures

769
00:42:59.820 --> 00:43:01.479
but this one uses a texture without depth

770
00:43:01.479 --> 00:43:05.080
That's why it is using X and Y

771
00:43:05.080 --> 00:43:10.559
So for this one, we use vector 2 instead of 3

772
00:43:10.559 --> 00:43:12.720
For direction, simply put direction

773
00:43:12.720 --> 00:43:16.520
Now, vector 2 toward where?

774
00:43:16.520 --> 00:43:17.679
up

775
00:43:17.679 --> 00:43:19.600
value needs to increase

776
00:43:19.600 --> 00:43:24.787
For scroll, we use the formula stated earlier

777
00:43:24.787 --> 00:43:27.759
which exist in bgMaterial

778
00:43:27.759 --> 00:43:31.800
bgMaterial, why don't you give me your texture Offset

779
00:43:31.800 --> 00:43:33.450
MainTexture's offset

780
00:43:33.450 --> 00:43:35.720
What we want to do is to change Offset value

781
00:43:35.720 --> 00:43:38.440
This directly become P

782
00:43:38.440 --> 00:43:41.872
How do we make adding happen? P0 + vt

783
00:43:41.872 --> 00:43:46.839
v equals direction * scrollSpeed

784
00:43:46.839 --> 00:43:48.320
that gives us v

785
00:43:48.320 --> 00:43:52.039
and then, put Time.deltaTime

786
00:43:52.039 --> 00:43:59.440
P = P0+, this value means v

787
00:43:59.440 --> 00:44:03.600
this one should be t

788
00:44:03.600 --> 00:44:06.759
Like this, we've made a scroll

789
00:44:06.759 --> 00:44:08.479
Save it

790
00:44:08.479 --> 00:44:12.880
And then play this

791
00:44:12.880 --> 00:44:14.720
We now see that it scrolls

792
00:44:14.720 --> 00:44:17.072
Now the game looks more like it

793
00:44:17.072 --> 00:44:18.924
with higher level of completeness

794
00:44:22.250 --> 00:44:26.150
Now, let's add the sound effects

795
00:44:26.150 --> 00:44:28.679
as the final step

796
00:44:28.679 --> 00:44:30.440
Go to the Asset Store

797
00:44:30.440 --> 00:44:37.800
Let's first download the Weapon Sound Pack from the Asset Store

798
00:44:37.800 --> 00:44:41.800
Search for Weapon Soldier Sounds Pack in the Asset Store

799
00:44:41.800 --> 00:44:47.679
Here, you'll see various gun related sound effects available

800
00:44:47.679 --> 00:44:49.960
Let's click this one

801
00:44:49.960 --> 00:44:51.559
Weapon Soldier Sounds Pack

802
00:44:51.559 --> 00:44:56.479
Open it in Unity

803
00:44:56.479 --> 00:45:01.639
You can download it from the Package Manager here

804
00:45:01.639 --> 00:45:04.199
Once the download is complete, click the Import button

805
00:45:04.199 --> 00:45:10.559
Let's import it into our project

806
00:45:10.559 --> 00:45:15.359
It has been added to the project, and now let's import another one

807
00:45:15.359 --> 00:45:19.959
This time, we will also import the explosion effects

808
00:45:19.959 --> 00:45:25.720
Let's search for Grenade Sound FX now

809
00:45:25.720 --> 00:45:26.839
This one is Free

810
00:45:26.839 --> 00:45:28.640
Grenade Sound FX

811
00:45:28.640 --> 00:45:33.519
Click this one

812
00:45:33.519 --> 00:45:35.469
Also, open in Unity

813
00:45:35.469 --> 00:45:39.720
Download it from the Package Manager

814
00:45:39.720 --> 00:45:47.600
Also import project to add it to our project

815
00:45:47.600 --> 00:45:50.640
So, for the bullet sound, it should play something like

816
00:45:50.640 --> 00:45:52.959
bang! or pow! when the bullet is fired

817
00:45:52.959 --> 00:45:59.399
So, let's add the sound to the bullet prefab

818
00:45:59.399 --> 00:46:03.006
We'll set it up like this so that the bullet prefab

819
00:46:03.006 --> 00:46:04.679
can play the sound

820
00:46:04.679 --> 00:46:07.436
Let's choose which sound

821
00:46:07.436 --> 00:46:09.320
we will use for the bullet

822
00:46:09.320 --> 00:46:12.440
Now, open the Mental Dream asset

823
00:46:12.440 --> 00:46:14.279
and you'll see the Soldier Sounds Pack

824
00:46:14.279 --> 00:46:18.359
From there, let's take

825
00:46:18.359 --> 00:46:20.920
the Fire sound and use it

826
00:46:20.920 --> 00:46:24.519
So, select the bullet in the Prefab folder

827
00:46:24.519 --> 00:46:26.819
then drag and drop the Fire sound

828
00:46:26.819 --> 00:46:30.279
from the Soldier Sounds Pack like this

829
00:46:30.279 --> 00:46:33.160
Then, the AudioSource component

830
00:46:33.160 --> 00:46:34.160
which will allow us to control the sound

831
00:46:34.160 --> 00:46:36.640
will be automatically added

832
00:46:36.640 --> 00:46:40.000
and the AudioClip will be set to "Fire

833
00:46:40.000 --> 00:46:43.519
This will do for us

834
00:46:43.519 --> 00:46:45.040
Let's go and play

835
00:46:45.040 --> 00:46:50.320
Let's see how it's implemented

836
00:46:50.320 --> 00:46:52.820
The sound of firing bullets

837
00:46:52.820 --> 00:46:56.000
is implemented very easily

838
00:46:56.000 --> 00:46:57.950
For the explosion effect

839
00:46:57.950 --> 00:46:59.920
you can play a boom sound when there's explosion

840
00:46:59.920 --> 00:47:02.870
Now, let's go to the explosion effect

841
00:47:02.870 --> 00:47:04.320
and work on adding the sound there as well

842
00:47:04.320 --> 00:47:06.359
Since it might be hard to find the explosion effect directly

843
00:47:06.359 --> 00:47:09.079
select this one at the Prefab

844
00:47:09.079 --> 00:47:10.480
and then choose the Enemy

845
00:47:10.480 --> 00:47:14.330
In the Enemy, you can find the part registered in the Explosion Factory

846
00:47:14.330 --> 00:47:16.352
where the explosion effect is located

847
00:47:16.359 --> 00:47:19.159
By clicking on it here, you can jump directly

848
00:47:19.159 --> 00:47:20.640
to where it's located

849
00:47:20.640 --> 00:47:21.990
Like this, you can jump directly

850
00:47:21.990 --> 00:47:25.640
to the location of this Prefab

851
00:47:25.640 --> 00:47:27.720
So, let's select this

852
00:47:27.720 --> 00:47:32.720
We can simply drag and drop it here

853
00:47:32.720 --> 00:47:34.040
To this explosion effect

854
00:47:34.040 --> 00:47:38.200
Let's register the asset we want to use here

855
00:47:38.200 --> 00:47:39.320
Since this is explosion effect

856
00:47:39.320 --> 00:47:42.119
If you open the Grenade Sound FX

857
00:47:42.119 --> 00:47:43.839
you'll see the grenade sound listed there

858
00:47:43.839 --> 00:47:46.119
This one, grenade

859
00:47:46.119 --> 00:47:49.880
Among these, if we grab the one that says Grenade 5 Shots

860
00:47:49.880 --> 00:47:53.040
and drag and drop it here

861
00:47:53.040 --> 00:47:55.200
Then it will be registered like this

862
00:47:55.200 --> 00:47:56.920
Shall we play again?

863
00:47:56.920 --> 00:48:00.559
Since it has been applied to the original Prefab file

864
00:48:00.559 --> 00:48:03.320
if you play

865
00:48:03.320 --> 00:48:05.000
How is it?

866
00:48:05.000 --> 00:48:07.799
By simply moving with our cube

867
00:48:07.799 --> 00:48:10.040
then assigning the player, enemy, bullets, background

868
00:48:10.040 --> 00:48:12.760
and finally the sound were added into

869
00:48:12.760 --> 00:48:14.679
doesn't the completeness increase suddenly?

870
00:48:14.679 --> 00:48:20.200
We've added the explosion effect

871
00:48:20.200 --> 00:48:24.320
If you want to add background sound to finish it off

872
00:48:24.320 --> 00:48:27.670
For the background sound, it would be good for you

873
00:48:27.670 --> 00:48:30.000
to find data that matches the feeling you're going for

874
00:48:30.000 --> 00:48:34.959
In my case, I searched for metal under SS2

875
00:48:34.959 --> 00:48:40.320
And then I found something like Eternity Djent Metal Scfi Horror Music Pack here

876
00:48:40.320 --> 00:48:45.040
Select the Free version

877
00:48:46.200 --> 00:48:48.720
I downloaded it from Unity

878
00:48:48.720 --> 00:48:51.359
So, download it

879
00:48:51.359 --> 00:48:54.480
When download is complete, import it

880
00:48:54.480 --> 00:48:57.600
You could download them all but there are too many data

881
00:48:57.600 --> 00:49:02.160
I will select this number 6, named loop

882
00:49:02.160 --> 00:49:06.880
and Import this one to our project

883
00:49:06.880 --> 00:49:07.920
worked right?

884
00:49:07.959 --> 00:49:11.279
Then, let's register this and try using it in our project

885
00:49:11.279 --> 00:49:14.279
It seems like you want to add the background sound

886
00:49:14.279 --> 00:49:17.324
by dragging and dropping it into the background

887
00:49:17.324 --> 00:49:19.074
So where is it?

888
00:49:19.074 --> 00:49:23.119
If you open the Audio assets, you'll see the music

889
00:49:23.119 --> 00:49:25.269
In this folder, you'll find the one we've added

890
00:49:25.269 --> 00:49:26.400
Right over here

891
00:49:26.400 --> 00:49:29.760
Drag and drop this file to add it

892
00:49:35.871 --> 00:49:39.921
Then, this background sound for the title will play

893
00:49:39.921 --> 00:49:41.559
continuously in an infinite loop

894
00:49:41.559 --> 00:49:44.960
Finally, if you play it

895
00:50:00.761 --> 00:50:02.911
you'll have created a plane game

896
00:50:02.911 --> 00:50:05.200
with the metal sound as the background music

897
00:50:05.200 --> 00:50:07.050
You can change musics

898
00:50:07.050 --> 00:50:09.320
according to your preferences

899
00:50:09.320 --> 00:50:14.239
With that, we've completed applying all the sounds

900
00:50:14.239 --> 00:50:17.440
Let's summarize the content we've learned in this lesson

901
00:50:17.440 --> 00:50:20.740
First, we upgraded the player, enemy

902
00:50:20.740 --> 00:50:23.640
and bullets to the alpha version

903
00:50:23.640 --> 00:50:27.140
We learned how to use the Asset Store for this purpose

904
