GCC Academy

3
00:00:27.520 --> 00:00:29.206
Hello again

4
00:00:29.207 --> 00:00:32.385
I am Park Hyung-seon, in charge of game planning
for action RPG balance

5
00:00:33.119 --> 00:00:39.655
This session will cover how to adjust health
in RPG battles to match the intended battle duration

6
00:00:39.880 --> 00:00:44.172
To establish a baseline for player combat balance,
we will discuss:

7
00:00:44.172 --> 00:00:48.887
How to determine the number of basic attacks needed
to defeat a mob

8
00:00:49.465 --> 00:00:55.105
And how to set the duration of a battle round

9
00:00:55.393 --> 00:01:02.131
Based on these criteria, we will define and structure
the values for player and enemy's attack power,

10
00:01:02.132 --> 00:01:05.295
health, and other related stats to create a standard baseline

11
00:01:05.295 --> 00:01:09.715
Distributing HP to Match the Battle Duration

12
00:01:10.080 --> 00:01:13.468
Distributing Health to Match RPG Battle Duration

13
00:01:14.360 --> 00:01:20.069
In the previous session, we set an initial rule
where a mob would be defeated

14
00:01:20.314 --> 00:01:23.495
after being hit by a player's basic attack four times

15
00:01:24.120 --> 00:01:26.726
However, this single rule

16
00:01:27.253 --> 00:01:31.482
is insufficient for balancing combat in an action MORPG

17
00:01:32.025 --> 00:01:35.678
To refine the balance, we will introduce

18
00:01:35.959 --> 00:01:39.114
more detailed parameters to enhance the game mechanics

19
00:01:43.440 --> 00:01:48.709
Let's distribute the HP for the RPG battle duration

20
00:01:49.360 --> 00:01:52.589
First, let's add a standard

21
00:01:53.019 --> 00:01:57.216
based on the player's basic attacks

22
00:01:58.096 --> 00:02:01.347
As shown, we have the attack sequence

23
00:02:01.912 --> 00:02:03.454
The basic attacks

24
00:02:03.919 --> 00:02:08.442
For one, two, three, and four attacks,

25
00:02:09.052 --> 00:02:13.527
Each tap triggers a corresponding attack animation

26
00:02:14.385 --> 00:02:17.007
When the player's character attacks,

27
00:02:17.273 --> 00:02:21.983
if a mob is hit during these animations,
it takes damage,

28
00:02:21.983 --> 00:02:24.780
and the basic attack sequence concludes

29
00:02:25.390 --> 00:02:29.910
Simply put, a four-hit animation sequence must be created,

30
00:02:30.791 --> 00:02:32.860
like one, two, three, and boom

31
00:02:32.860 --> 00:02:36.244
So it's a four-in-one animation

32
00:02:37.312 --> 00:02:42.522
When a player taps the basic attack button repeatedly,

33
00:02:42.522 --> 00:02:47.070
the character performs consecutive attacks,
dealing damage to the mob

34
00:02:47.759 --> 00:02:51.191
A maximum of four basic attacks can be chained together
before the sequence resets

35
00:02:51.865 --> 00:02:56.305
The final hit in the sequence delivers a stabbing motion
to conclude the attack cycle

36
00:02:56.960 --> 00:03:01.384
When designing combat animations,

37
00:03:01.384 --> 00:03:08.478
there are additional elements to consider beyond
just basic attack animations

38
00:03:08.977 --> 00:03:12.373
But there needs to be things such as,

39
00:03:13.074 --> 00:03:15.651
for characters,

40
00:03:16.540 --> 00:03:17.326
idle animations,

41
00:03:17.692 --> 00:03:18.692
walking animations,

42
00:03:18.914 --> 00:03:20.990
attack animations like these,

43
00:03:21.234 --> 00:03:22.037
hit reaction animations,

44
00:03:22.805 --> 00:03:25.077
running animations, if applicable,

45
00:03:25.286 --> 00:03:27.142
knockback animations,

46
00:03:27.482 --> 00:03:28.103
and death animations

47
00:03:28.472 --> 00:03:31.240
These kinds of animation should be planned ahead

48
00:03:31.399 --> 00:03:35.743
For idle animations, slight breathing motions
or subtle movements

49
00:03:36.143 --> 00:03:40.558
should be incorporated to create a natural effect

50
00:03:40.880 --> 00:03:43.087
For attack animations, it is essential to synchronize

51
00:03:43.560 --> 00:03:46.421
the skill-based attacks and basic attacks properly

52
00:03:46.880 --> 00:03:48.160
For the basic attack,

53
00:03:48.637 --> 00:03:51.584
the attack timing should be planned

54
00:03:52.179 --> 00:03:56.757
in coordination with the animators

55
00:03:56.964 --> 00:04:01.962
to ensure smooth transitions and the perfect rhythm

56
00:04:02.521 --> 00:04:05.170
For this set of one, two, three, and four touches,

57
00:04:05.574 --> 00:04:09.816
game planners are usually not in charge of the fine-tuning

58
00:04:10.199 --> 00:04:14.341
Animators often fine-tune animation pacing
based on instinct

59
00:04:14.896 --> 00:04:18.930
However, this general concept of one, two, three, and four

60
00:04:19.273 --> 00:04:21.133
should be given by the game planner

61
00:04:21.559 --> 00:04:28.019
Game planners should provide general timing expectations

62
00:04:28.319 --> 00:04:33.089
for how long a full attack sequence should last

63
00:04:36.679 --> 00:04:39.225
Now, we will discuss skill planning

64
00:04:39.677 --> 00:04:44.731
and how skill planning impacts balance

65
00:04:45.600 --> 00:04:49.219
This adds a skill to the player

66
00:04:50.332 --> 00:04:54.799
When a player taps the skill button, a skill action is executed

67
00:04:55.519 --> 00:04:57.415
There are various types of skills,

68
00:04:57.426 --> 00:05:01.256
but let’s take an example of a jump attack skill,
where the player leaps and then strikes downward

69
00:05:01.780 --> 00:05:07.061
After executing the skill, there is a cooldown period

70
00:05:07.615 --> 00:05:10.269
For example, if a skill has a 20-second cooldown,

71
00:05:10.518 --> 00:05:14.036
it means the player can use it once every 20 seconds

72
00:05:15.439 --> 00:05:22.005
When a player activates the skill,
the character enters a skill execution state,

73
00:05:22.476 --> 00:05:25.861
performing an animation for the skill

74
00:05:26.399 --> 00:05:28.298
Once the skill is used,

75
00:05:28.563 --> 00:05:31.812
it enters a cooldown phase,
during which the skill is temporarily unavailable

76
00:05:32.302 --> 00:05:34.358
Once the cooldown period is over,

77
00:05:34.784 --> 00:05:37.539
the skill becomes usable again

78
00:05:38.160 --> 00:05:40.767
That's one example of skill planning

79
00:05:41.490 --> 00:05:45.453
When planning skills, an important consideration

80
00:05:45.880 --> 00:05:49.346
is damage calculation, which I will talk about now

81
00:05:49.535 --> 00:05:54.198
For instance, if we define basic attack damage in terms

82
00:05:54.198 --> 00:05:57.697
of damage per second (DPS),
we can apply the following formula:

83
00:05:59.000 --> 00:06:05.140
Skill damage = DPS × Skill multiplier of 7x

84
00:06:05.141 --> 00:06:07.190
This is a usual way of doing it

85
00:06:07.480 --> 00:06:09.571
We will delve into its details later,

86
00:06:09.912 --> 00:06:11.977
so consider this as a preview

87
00:06:16.119 --> 00:06:22.907
Now, let's talk about the average time for completing a stage

88
00:06:23.193 --> 00:06:26.709
If you have planned

89
00:06:26.986 --> 00:06:30.460
basic attacks and skill animations,

90
00:06:31.119 --> 00:06:36.715
the next step is to define an apt
average battle duration per stage

91
00:06:37.301 --> 00:06:40.362
For example, consider this

92
00:06:40.679 --> 00:06:45.424
What should be the ideal duration for a single battle?

93
00:06:45.761 --> 00:06:47.098
One, 30 seconds

94
00:06:47.343 --> 00:06:48.666
Two, 1 minute

95
00:06:49.000 --> 00:06:50.311
Three, 3 minutes

96
00:06:50.634 --> 00:06:52.269
Four, 30 minutes

97
00:06:52.548 --> 00:06:54.862
Finally, five, 1 hour

98
00:06:55.714 --> 00:06:57.144
For players,

99
00:06:58.011 --> 00:07:02.685
when determining the appropriate duration,

100
00:07:02.781 --> 00:07:05.706
consider what would feel most engaging

101
00:07:06.600 --> 00:07:09.878
The player enters the combat stage

102
00:07:10.842 --> 00:07:14.859
and fights against summoned mobs

103
00:07:15.160 --> 00:07:18.003
Players will utilize both basic attacks and skill-based attack

104
00:07:18.310 --> 00:07:21.306
 to defeat dozens of enemies

105
00:07:22.045 --> 00:07:25.303
before ultimately engaging in a boss battle

106
00:07:25.720 --> 00:07:30.038
Using the previously defined basic attack
and skill mechanics,

107
00:07:30.698 --> 00:07:34.126
players will engage in combat with mobs and bosses

108
00:07:34.744 --> 00:07:39.255
until the final boss is defeated

109
00:07:43.680 --> 00:07:46.993
By analyzing other MORPG games, we observe that

110
00:07:47.731 --> 00:07:52.280
early-stage battles typically last between 1 to 2 minutes,

111
00:07:52.646 --> 00:07:57.796
while late-stage battles extend
to approximately 7 to 8 minutes

112
00:07:58.119 --> 00:08:03.785
When designing a game, benchmarking
other successful titles

113
00:08:04.393 --> 00:08:06.805
is crucial to ensure

114
00:08:06.807 --> 00:08:12.618
that our combat duration is competitive and engaging

115
00:08:12.839 --> 00:08:14.956
So this comparison is very important

116
00:08:15.609 --> 00:08:20.286
So here is the average time for other games

117
00:08:20.839 --> 00:08:23.470
Let's first think about the thoughts behind this

118
00:08:23.902 --> 00:08:27.423
For example, if a game ends too quickly,

119
00:08:27.865 --> 00:08:30.650
like within 5 or 10 minutes of starting,

120
00:08:31.160 --> 00:08:34.049
early player retention may suffer

121
00:08:34.332 --> 00:08:38.463
Thus, early Stage 1-1 or 1-2

122
00:08:39.269 --> 00:08:42.473
should be short , from 50 seconds to 1 minute 20 seconds

123
00:08:43.180 --> 00:08:47.032
to quickly showcase the game's core mechanics

124
00:08:47.072 --> 00:08:51.555
After 2-3 hours of gameplay,

125
00:08:52.065 --> 00:08:53.462
battles should extend

126
00:08:53.462 --> 00:08:55.732
to around 2-3 minutes

127
00:08:56.000 --> 00:09:00.244
After one or two days of play, stage durations

128
00:09:00.831 --> 00:09:02.844
may reach 7 minutes

129
00:09:02.957 --> 00:09:06.556
or more in later stages, increasing the play time

130
00:09:07.119 --> 00:09:11.973
Since we are setting combat balance standards,

131
00:09:12.604 --> 00:09:19.128
we will use 3 minutes as the average battle clear time

132
00:09:19.679 --> 00:09:23.180
This 3-minute standard

133
00:09:23.770 --> 00:09:29.158
will serve as the basis for MORPG combat balancing,

134
00:09:29.566 --> 00:09:32.157
with early stages lasting 1-2 minutes

135
00:09:32.158 --> 00:09:35.694
and late-game encounters stretching to 7-8 minutes

136
00:09:36.500 --> 00:09:40.703
The balance can later be adjusted as necessary,

137
00:09:40.970 --> 00:09:42.544
so let's continue with 3 minutes

138
00:09:43.120 --> 00:09:45.742
Later, we can adjust the stages

139
00:09:46.408 --> 00:09:49.805
to 1-2 or 7-8 minutes after this work

140
00:09:50.020 --> 00:09:52.080
So let's start with the 3-minute mark

141
00:09:55.967 --> 00:10:02.066
How long will it take to defeat mobs
with basic attacks?

142
00:10:03.516 --> 00:10:07.060
4 basic attack hits take ~2 seconds to defeat one mob,

143
00:10:08.240 --> 00:10:13.278
and 2 seconds are required to move to a mob
after entering a stage

144
00:10:13.799 --> 00:10:20.799
Considering these factors, let's calculate the total time
needed to defeat 30 mobs

145
00:10:21.636 --> 00:10:23.008
Time to move to a mob

146
00:10:23.008 --> 00:10:25.557
after entering the stage,

147
00:10:25.991 --> 00:10:28.343
it will be like 2 seconds

148
00:10:28.799 --> 00:10:31.613
That will have four attacks

149
00:10:32.260 --> 00:10:34.774
Designing it this way,

150
00:10:35.601 --> 00:10:40.528
this means that, in this stage,

151
00:10:40.665 --> 00:10:44.803
we can decide how long it will take to defeat 30 mobs

152
00:10:44.902 --> 00:10:49.984
only using basic attacks

153
00:10:50.799 --> 00:10:56.876
It is easier to consider the time for movement
with the animation time

154
00:10:58.140 --> 00:11:02.100
So that's a good variable to work on

155
00:11:02.282 --> 00:11:07.080
Since we are working with four attacks in a pack,

156
00:11:07.799 --> 00:11:12.152
like slash, slash, slash, and boom

157
00:11:12.799 --> 00:11:18.018
So, if the animation isn't too slow,

158
00:11:18.366 --> 00:11:23.581
these four motions will take about 2 seconds,

159
00:11:24.080 --> 00:11:27.799
even 1 second or a little over that

160
00:11:28.187 --> 00:11:32.280
But the players don't just continuously attack

161
00:11:32.280 --> 00:11:35.432
They would move, attack, and move, then attack

162
00:11:35.433 --> 00:11:37.997
They would roll, they would dodge

163
00:11:38.002 --> 00:11:39.430
All these movements are included

164
00:11:39.430 --> 00:11:43.862
as the players attack, dodge, and move

165
00:11:44.349 --> 00:11:49.491
It is too complex to consider all these factors

166
00:11:49.799 --> 00:11:56.334
Therefore, let's just simply consider the movement
and the attack to have 2 seconds,

167
00:11:56.338 --> 00:12:04.020
which includes four attacks and some movement to dodge

168
00:12:04.028 --> 00:12:07.232
This will be easier to balance it out

169
00:12:07.799 --> 00:12:11.960
Therefore, 30 mobs, only using basic attack,

170
00:12:12.326 --> 00:12:14.092
including movement and dodge,

171
00:12:14.400 --> 00:12:17.799
will take, how long?

172
00:12:18.209 --> 00:12:25.799
We can merge the information that each mob
takes 2 seconds

173
00:12:26.134 --> 00:12:29.346
So for 30 mobs, 60 seconds

174
00:12:29.799 --> 00:12:31.799
That's the calculation

175
00:12:32.277 --> 00:12:39.126
Additional time for initial movement into the stage
may slightly extend the total duration

176
00:12:44.253 --> 00:12:49.068
Let's now analyze

177
00:12:49.733 --> 00:12:53.952
combat when using only skills for one minute

178
00:12:54.799 --> 00:12:57.736
A skill has a cooldown of 20 seconds

179
00:12:57.928 --> 00:13:01.668
Each skill use defeats 3 mobs

180
00:13:02.968 --> 00:13:05.804
Then, within 1 minute, how many can one fight?

181
00:13:06.799 --> 00:13:08.799
I mentioned the cooldown time

182
00:13:08.799 --> 00:13:12.921
Let's just say that there

183
00:13:12.921 --> 00:13:15.687
is no MP usage to consider

184
00:13:16.070 --> 00:13:20.433
Let's just consider the cooldown time for this skill

185
00:13:20.799 --> 00:13:23.511
So the player can use it every 20 seconds

186
00:13:24.014 --> 00:13:27.200
Within 1 minute, the skill can be used 3 times

187
00:13:27.970 --> 00:13:33.786
Total mobs defeated in 1 minute will be 3 mobs

188
00:13:34.123 --> 00:13:35.233
This is how it works

189
00:13:39.973 --> 00:13:45.600
Then it will defeat 9 mobs

190
00:13:48.161 --> 00:13:52.799
Thus, when using only skills, for a whole minute,

191
00:13:54.104 --> 00:13:58.228
the player uses 3 skills in a minute

192
00:13:59.279 --> 00:14:02.641
Since one skill can defeat 3 mobs,

193
00:14:02.641 --> 00:14:05.908
the player can defeat 9 mobs in total

194
00:14:09.624 --> 00:14:19.799
Let's now establish damage standards
for basic and skill attacks

195
00:14:21.129 --> 00:14:24.964
Let's set the mob HP at 100

196
00:14:26.219 --> 00:14:29.789
Slash, slash, slash, and boom, that's the basic attack

197
00:14:31.436 --> 00:14:36.101
that takes 2 seconds

198
00:14:36.611 --> 00:14:41.113
At the fourth attack, a mob dies

199
00:14:42.413 --> 00:14:49.438
So it dies after four basic attacks

200
00:14:49.936 --> 00:14:54.888
This is based on what we decided before

201
00:14:55.620 --> 00:15:01.508
What is the optimal attack count
to keep the player engaged?

202
00:15:01.508 --> 00:15:04.014
We decided with four

203
00:15:04.266 --> 00:15:05.718
That's the reason

204
00:15:06.292 --> 00:15:08.644
But to die after four attacks,

205
00:15:08.644 --> 00:15:11.402
considering the mob's HP as 100,

206
00:15:11.692 --> 00:15:17.026
it requires four hits of 25 damage

207
00:15:17.666 --> 00:15:20.799
So, if all four attacks are the same,

208
00:15:22.051 --> 00:15:26.799
each basic attack should deal approximately 25 HP damage

209
00:15:28.293 --> 00:15:35.530
So four attacks will kill the mob

210
00:15:36.348 --> 00:15:41.426
To calculate the DPS for basic attacks,

211
00:15:43.374 --> 00:15:46.098
 each basic attack deals 25 damage,

212
00:15:46.799 --> 00:15:51.075
and a full four-hit sequence totals 100 damage

213
00:15:53.225 --> 00:15:57.957
So for a second, it will yield 50 damage

214
00:15:58.799 --> 00:16:05.799
 Since the entire sequence occurs within 2 seconds,

215
00:16:05.799 --> 00:16:10.621
the basic attack's damage per second is 50

216
00:16:11.101 --> 00:16:14.799
As mentioned earlier,

217
00:16:16.135 --> 00:16:22.228
basic attacks are executed within 2 seconds,

218
00:16:23.907 --> 00:16:26.281
dealing damage within that timeframe

219
00:16:26.544 --> 00:16:29.544
Based on this standard, the calculation is as follows

220
00:16:32.620 --> 00:16:38.365
Since basic attacks occur over 2 seconds,

221
00:16:38.365 --> 00:16:39.451
the total damage must be divided

222
00:16:39.571 --> 00:16:43.221
The total damage dealt is 100,

223
00:16:43.799 --> 00:16:45.799
and this is executed within 2 seconds

224
00:16:45.799 --> 00:16:47.398
Slash, slash, slash, and  boom

225
00:16:48.008 --> 00:16:50.670
That's two seconds

226
00:16:50.670 --> 00:16:53.059
So we need to determine the damage dealt per second

227
00:16:53.832 --> 00:16:57.289
Dividing 100 by 2 results in 50

228
00:16:57.289 --> 00:17:02.140
This allows for a simpler approach
to thinking about the calculation

229
00:17:02.799 --> 00:17:06.800
Ultimately, this process determines DPS

230
00:17:07.611 --> 00:17:10.800
It is the amount of damage dealt per second

231
00:17:11.832 --> 00:17:16.800
To calculate one-second damage, we follow this method

232
00:17:20.800 --> 00:17:23.950
Now, let’s determine

233
00:17:24.524 --> 00:17:27.081
the DPS for skill attacks

234
00:17:28.294 --> 00:17:31.077
Previously, we calculated

235
00:17:31.696 --> 00:17:33.529
the DPS

236
00:17:33.800 --> 00:17:36.800
for basic attacks,

237
00:17:37.702 --> 00:17:41.500
which determines how much damage is applied per second,

238
00:17:42.073 --> 00:17:45.115
which works as a reference for various damage calculations

239
00:17:46.712 --> 00:17:50.800
Let’s examine a different skill

240
00:17:51.309 --> 00:17:53.622
For example, let’s assume a mage

241
00:17:54.366 --> 00:18:00.800
who casts homing Magic Missiles

242
00:18:01.800 --> 00:18:04.489
Before using the skill, there is an initial state

243
00:18:04.978 --> 00:18:10.800
When the skill is cast, three projectiles
are launched as Magic Missiles

244
00:18:11.349 --> 00:18:13.800
These homing missiles

245
00:18:14.423 --> 00:18:19.489
each hit one of three different mobs

246
00:18:19.800 --> 00:18:27.800
Now, let’s assume each Magic Missile deals 100 damage

247
00:18:28.158 --> 00:18:33.177
Since we previously set the mob health to 100,

248
00:18:33.671 --> 00:18:37.263
this means a mob will die after being hit
by a single Magic Missile

249
00:18:37.829 --> 00:18:41.187
Therefore, with three projectiles,
three mobs can be defeated

250
00:18:41.187 --> 00:18:44.121
Since all three projectiles are launched at once,

251
00:18:44.785 --> 00:18:46.800
three enemies are eliminated simultaneously

252
00:18:47.498 --> 00:18:51.457
As a result, the total damage inflicted is 300

253
00:18:52.377 --> 00:18:54.636
Each projectile deals 100 damage,

254
00:18:54.636 --> 00:19:00.775
and three projectiles are launched, bringing the total to 300

255
00:19:01.479 --> 00:19:06.296
The sequence follows: button press → casting → cooldown

256
00:19:07.019 --> 00:19:13.746
Similarly, this skill has a cooldown time of 20 seconds

257
00:19:14.464 --> 00:19:19.879
Now, let’s determine the DPS for skill attacks

258
00:19:20.598 --> 00:19:24.021
This skill can be used once every 20 seconds

259
00:19:24.351 --> 00:19:26.311
Each time it is used, it launches three Magic Missiles

260
00:19:26.800 --> 00:19:30.292
Since each Magic Missile deals 100 damage,
the total damage per use is 300

261
00:19:31.041 --> 00:19:32.524
Thus, the total damage output is 300,

262
00:19:32.525 --> 00:19:34.434
since there are three projectiles

263
00:19:34.800 --> 00:19:36.863
Given that the skill has a 20-second cooldown,

264
00:19:39.847 --> 00:19:45.176
we get the DPS of 15

265
00:19:46.793 --> 00:19:51.241
The total damage is 300,
and the skill has a 20-second cooldown

266
00:19:51.879 --> 00:19:56.322
Therefore, the damage per second is calculated as 15

267
00:19:56.616 --> 00:20:02.617
For instance, since the skill has a cooldown of 20 seconds,

268
00:20:03.334 --> 00:20:07.491
within one minute, it can be used three times

269
00:20:07.800 --> 00:20:11.422
Multiplying 300 by 3 gives a total of 900 damage per minute

270
00:20:12.328 --> 00:20:16.394
To determine the per-second damage, we divide 900 by 60

271
00:20:16.396 --> 00:20:19.398
This results in a DPS of 15

272
00:20:19.398 --> 00:20:21.800
That's how the calculation works

273
00:20:21.800 --> 00:20:26.757
This calculation method allows us

274
00:20:27.301 --> 00:20:30.800
to determine the damage output per second

275
00:20:30.800 --> 00:20:32.800
Using this, we can also determine
the damage output per minute

276
00:20:32.800 --> 00:20:37.800
Establishing damage benchmarks based on time
makes calculations more structured

277
00:20:41.484 --> 00:20:45.818
Now, let’s further discuss

278
00:20:46.389 --> 00:20:49.485
the damage per second for basic and skill attacks

279
00:20:50.853 --> 00:20:53.211
A character can execute two basic attacks per second

280
00:20:54.353 --> 00:20:57.135
Each second, a basic attack deals 50 damage

281
00:20:57.680 --> 00:20:59.869
Thus, the basic attack’s DPS is 50

282
00:21:00.626 --> 00:21:02.272
That's the calculation

283
00:21:03.644 --> 00:21:07.787
Every 20 seconds, a skill deals 300 damage per use

284
00:21:08.107 --> 00:21:10.714
This results in a skill DPS of 15

285
00:21:10.969 --> 00:21:12.852
That's what we have

286
00:21:13.710 --> 00:21:19.800
From this, the skill’s DPS is 15

287
00:21:20.144 --> 00:21:22.144
Now, let’s combine both values

288
00:21:22.972 --> 00:21:27.979
Since the player continuously executes basic attacks

289
00:21:27.979 --> 00:21:30.457
while moving, dodging, and using skills,

290
00:21:30.457 --> 00:21:33.492
we assume these occur simultaneously

291
00:21:34.093 --> 00:21:37.801
Given this, we can determine

292
00:21:38.024 --> 00:21:41.028
the total damage dealt per minute,

293
00:21:41.338 --> 00:21:43.994
per two minutes, per three minutes, and so on

294
00:21:44.155 --> 00:21:46.700
By computing it per second,

295
00:21:47.349 --> 00:21:49.715
we arrive at the total DPS for basic attack as 50

296
00:21:50.417 --> 00:21:53.186
and that for skill attacks as 15

297
00:21:53.784 --> 00:21:58.573
Adding these together results in a total DPS of 65

298
00:21:58.800 --> 00:22:00.904
This is the total DPS,

299
00:22:00.904 --> 00:22:02.941
or the total damage

300
00:22:03.297 --> 00:22:09.800
Thus, the total DPS for the player character is set at 65

301
00:22:11.285 --> 00:22:15.767
Now, let’s discuss the damage per second
for both basic and skill attacks

302
00:22:17.457 --> 00:22:21.194
The DPS for basic attacks is 50

303
00:22:21.936 --> 00:22:25.266
The DPS for skill attacks is 15

304
00:22:25.800 --> 00:22:31.310
Therefore, the total DPS is calculated as 50 + 15,

305
00:22:31.311 --> 00:22:32.311
which is 65

306
00:22:33.332 --> 00:22:38.495
Multiplying 65 by 180 seconds for three minutes,

307
00:22:39.103 --> 00:22:42.636
the total damage a player can deal over 3 minutes is 11,700

308
00:22:44.047 --> 00:22:47.681
Therefore, the total enemy health across 3 minutes
should be set at 11,700

309
00:22:47.886 --> 00:22:51.044
Let’s simplify this explanation further

310
00:22:51.691 --> 00:22:55.456
For example, based on our established standard:

311
00:22:55.987 --> 00:22:59.274
A mob dies after taking four hits

312
00:22:59.341 --> 00:23:04.341
The game is designed to be cleared within 3 minutes

313
00:23:04.364 --> 00:23:09.184
These assumptions serve as the foundation
for balancing gameplay

314
00:23:10.644 --> 00:23:13.895
Since the DPS is 65

315
00:23:14.290 --> 00:23:17.865
and the game is cleared in 3 minutes,
multiply by 180

316
00:23:18.193 --> 00:23:20.416
means that if we play at maximum efficiency,

317
00:23:20.416 --> 00:23:24.619
we can deal a total of 11,700 damage over 3 minutes

318
00:23:25.148 --> 00:23:32.020
During these 3 minutes, groups of mob

319
00:23:32.021 --> 00:23:34.087
and the boss mob will appear

320
00:23:34.498 --> 00:23:39.800
If their combined health is set to 11,700,
they will be able to withstand the attacks

321
00:23:39.956 --> 00:23:42.662
Since we can deal 11,700 damage,

322
00:23:43.161 --> 00:23:46.279
assuming no defense and only considering health,

323
00:23:46.735 --> 00:23:50.410
if the mobs collectively have 11,700 health,

324
00:23:50.694 --> 00:23:53.599
the game will end within the 3-minute timeframe

325
00:23:54.552 --> 00:23:59.109
This is where the concept of total player attack power
equaling total enemy health comes into play

326
00:23:59.794 --> 00:24:03.773
The total damage a player can deal in 3 minutes is 11,700,

327
00:24:04.223 --> 00:24:07.757
and the total enemy health over 3 minutes is also 11,700

328
00:24:08.864 --> 00:24:13.967
The enemies include dozens of mob
and one boss mob

329
00:24:17.812 --> 00:24:22.348
Now, let’s distribute the health

330
00:24:23.159 --> 00:24:28.318
Let’s assume that players spend
1 minute and 30 seconds fighting mobs

331
00:24:28.977 --> 00:24:34.120
and another 1 minute and 30 seconds
fighting the boss mob

332
00:24:34.580 --> 00:24:38.216
This means the game will be completed within 3 minutes

333
00:24:39.359 --> 00:24:44.329
So, we divide the total health,

334
00:24:44.472 --> 00:24:46.855
setting 5850 as the total health of the mob
and the boss mob,

335
00:24:47.218 --> 00:24:51.941
splitting the 11,700 evenly

336
00:24:56.406 --> 00:25:02.800
However, we previously set
a mob's health at 100

337
00:25:03.800 --> 00:25:06.649
because we assumed it dies after four hits,

338
00:25:06.653 --> 00:25:09.600
with each hit dealing 25 damage

339
00:25:10.957 --> 00:25:13.338
Thus, the health of a mob is 100

340
00:25:13.611 --> 00:25:17.329
To make the numbers more uniform,

341
00:25:18.090 --> 00:25:23.190
let's adjust the total HP
of the mob group to 5,800,

342
00:25:23.191 --> 00:25:25.453
setting the number of mobs to 58

343
00:25:26.143 --> 00:25:29.224
The boss mob's health is then adjusted to 5,900

344
00:25:29.434 --> 00:25:32.139
This adjustment results in a more rounded number

345
00:25:33.287 --> 00:25:36.728
Since the mob health is set at 100,

346
00:25:37.001 --> 00:25:39.725
dividing 5,850 doesn't align well with this unit

347
00:25:39.899 --> 00:25:41.564
So adjust it to 5,800

348
00:25:42.118 --> 00:25:45.065
and subtract 50 from the total HP of mobs

349
00:25:45.628 --> 00:25:49.013
while adding 50 to the boss mob's HP
to balance the values

350
00:25:50.470 --> 00:25:55.285
Now, within the 3-minute playtime,

351
00:25:56.151 --> 00:25:58.157
mobs appear with 100 health each,

352
00:25:58.468 --> 00:26:02.557
with 58 total mobs, resulting in 5,800 total health

353
00:26:02.557 --> 00:26:06.820
The boss mob has 5,900 health

354
00:26:08.784 --> 00:26:11.087
That's what we've been looking at

355
00:26:11.918 --> 00:26:16.179
Let’s summarize the first round
of combat balance adjustments

356
00:26:17.187 --> 00:26:19.610
A mob dies after four hits

357
00:26:20.016 --> 00:26:23.446
Basic attacks can be performed four times over 2 seconds,

358
00:26:24.019 --> 00:26:26.369
dealing 25 damage per hit

359
00:26:26.999 --> 00:26:30.169
Skill attacks can be used once every 20 seconds,

360
00:26:30.661 --> 00:26:35.946
dealing 100 damage to three enemies per use

361
00:26:36.509 --> 00:26:40.469
58 mobs appear, each with 100 health

362
00:26:41.137 --> 00:26:43.339
The boss mob has 5,900 health

363
00:26:43.723 --> 00:26:46.470
A player can deal 65 DPS

364
00:26:46.977 --> 00:26:50.316
The total damage dealt over 3 minutes is 11,700

365
00:26:50.800 --> 00:26:54.631
Combat is designed to last for an average of 3 minutes

366
00:26:55.220 --> 00:26:59.178
This is what we have so far

367
00:27:00.008 --> 00:27:05.800
All these are derived from the initial balancing criteria

368
00:27:06.296 --> 00:27:09.412
Since we set mobs to die after four hits,

369
00:27:09.774 --> 00:27:12.040
we established their health at 100,

370
00:27:12.413 --> 00:27:16.978
ensuring that four basic attacks, as in 25 x 4

371
00:27:17.970 --> 00:27:21.424
Similarly, skill attacks can be used once every 20 seconds,

372
00:27:21.866 --> 00:27:26.249
dealing 100 damage to three enemies at a time

373
00:27:26.255 --> 00:27:30.112
With these calculations, we derived DPS values

374
00:27:30.307 --> 00:27:33.029
for basic and skill attacks

375
00:27:33.305 --> 00:27:36.140
Basic attack DPS is 50,
skill attack DPS is 15

376
00:27:36.235 --> 00:27:42.343
So the total DPS combining the two will be 65

377
00:27:43.064 --> 00:27:46.660
And the mobs have 100 health each,
with a total of 58 appearing

378
00:27:46.660 --> 00:27:49.386
The boss monster has 5,900 health

379
00:27:49.869 --> 00:27:56.608
It comes from the total damage they can inflict
over three minutes as 11,700

380
00:27:57.171 --> 00:28:00.720
with the total average numbers for the enemies

381
00:28:03.917 --> 00:28:07.593
Combat Balance Criteria Setup

382
00:28:09.800 --> 00:28:13.205
We have now gone through the process
of setting up combat balance criteria

383
00:28:14.372 --> 00:28:18.678
If the game being developed follows
turn-based combat rules,

384
00:28:18.980 --> 00:28:21.252
there are no variables related to movement or action,

385
00:28:21.860 --> 00:28:26.039
meaning that the initial criteria we set will likely align well

386
00:28:26.491 --> 00:28:28.256
There will be an attack order,

387
00:28:28.525 --> 00:28:31.928
the calculations will remain consistent
for the turn-based combat

388
00:28:31.928 --> 00:28:36.800
Even if the balance is designed using spreadsheets,
there aren't dynamic variables

389
00:28:36.800 --> 00:28:38.800
so the numbers will largely hold up

390
00:28:42.474 --> 00:28:47.234
However, since we are discussing an action RPG,

391
00:28:47.753 --> 00:28:51.677
balancing is significantly more complex
than in turn-based combat

392
00:28:52.774 --> 00:28:54.497
Various factors influence the calculations,

393
00:28:54.896 --> 00:28:57.646
such as the amount of damage a player can deal per minute

394
00:28:58.020 --> 00:29:01.418
and the conditions under which
multiple mobs are hit simultaneously

395
00:29:02.514 --> 00:29:07.467
For instance, a player may evade attacks
by stepping back while attacking

396
00:29:08.800 --> 00:29:12.656
If mobs are clustered closely together,

397
00:29:13.425 --> 00:29:15.335
a single attack may hit multiple enemies instead of just one,

398
00:29:15.704 --> 00:29:20.022
allowing for faster enemy elimination

399
00:29:21.920 --> 00:29:27.392
Action RPGs involve variables
like character movement and dodging,

400
00:29:28.572 --> 00:29:34.390
and the number of mobs affected by basic attacks
depends on how they are positioned

401
00:29:39.264 --> 00:29:44.382
Without any established criteria,
balance adjustments become impossible,

402
00:29:44.590 --> 00:29:47.694
ultimately reducing the game’s quality and fun factor

403
00:29:48.018 --> 00:29:52.055
Because action RPGs contain these unpredictable elements,

404
00:29:52.286 --> 00:29:56.073
Excel balance calculations
may not always be perfectly accurate

405
00:29:56.787 --> 00:30:00.480
That said, if no criteria are set from the start,

406
00:30:00.481 --> 00:30:04.200
there is no way to achieve balance at all

407
00:30:04.200 --> 00:30:06.349
This would negatively impact the game
and the player experience

408
00:30:07.076 --> 00:30:09.794
Instead, by establishing foundational balance criteria,

409
00:30:09.958 --> 00:30:11.384
such as mobs dying after four hits

410
00:30:11.384 --> 00:30:14.281
or the number of basic attacks landing within two seconds,

411
00:30:14.596 --> 00:30:17.537
we can first set an initial balance

412
00:30:18.075 --> 00:30:21.930
and, by fine-tuning the rules,

413
00:30:21.936 --> 00:30:25.003
we can further refine the balance to make it more precise

414
00:30:29.867 --> 00:30:35.472
Action MORPGs produce different outcomes
depending on the player’s skill level

415
00:30:36.086 --> 00:30:38.631
We can assume three types of players,

416
00:30:38.632 --> 00:30:41.349
highly skilled, unskilled, and average players,

417
00:30:42.014 --> 00:30:45.709
to design a combat AI to test different combat scenarios

418
00:30:46.341 --> 00:30:48.845
Once the auto-combat AI is developed,

419
00:30:49.359 --> 00:30:53.953
we can apply the first-round balance calculations
to both player characters and mobs

420
00:30:54.473 --> 00:30:58.682
to see how much these calculations
deviate from the expected values

421
00:30:59.425 --> 00:31:02.793
However, since developers are generally
more skilled at playing their own games,

422
00:31:03.239 --> 00:31:06.160
the balance should be based on less skilled players

423
00:31:06.505 --> 00:31:09.834
For example, if we design AI-driven combat,

424
00:31:10.181 --> 00:31:12.545
we can establish simple rules like using skills in sequence

425
00:31:13.233 --> 00:31:18.181
or having the character move and attack when an enemy
enters its range

426
00:31:18.182 --> 00:31:21.035
This is how we plan the AI rules

427
00:31:21.665 --> 00:31:26.206
By creating AI rules and implementing auto-combat,

428
00:31:26.682 --> 00:31:27.972
we can test

429
00:31:28.832 --> 00:31:34.491
whether the Excel balance calculations
match actual gameplay

430
00:31:35.332 --> 00:31:40.473
If not, we can apply correction factors
like multiplying by 0.3 or 0.2

431
00:31:41.109 --> 00:31:44.625
to adjust the values closer to real gameplay conditions

432
00:31:45.068 --> 00:31:50.387
Since it’s impractical to manually playtest every scenario,

433
00:31:50.957 --> 00:31:53.803
if the game has 500 stages,

434
00:31:54.066 --> 00:31:56.096
such as Stage 1,

435
00:31:56.447 --> 00:31:59.752
Stage 50, Stage 100, and Stage 150,

436
00:32:00.022 --> 00:32:03.214
we can test select stages

437
00:32:03.553 --> 00:32:06.096
and make broader balance adjustments

438
00:32:06.709 --> 00:32:09.988
This method is called sampling balance tuning

439
00:32:10.432 --> 00:32:14.348
If balance is refined at key stages,

440
00:32:14.721 --> 00:32:17.826
we assume the values between them
will also be reasonably balanced

441
00:32:17.826 --> 00:32:21.292
This way, we don’t need to test every single stage,

442
00:32:21.316 --> 00:32:25.201
and we can still fine-tune the balance efficiently

443
00:32:25.202 --> 00:32:28.879
By making adjustments based on those results,

444
00:32:29.064 --> 00:32:32.345
we can gradually refine the balance

445
00:32:43.871 --> 00:32:46.035
This concludes today's lecture

446
00:32:46.470 --> 00:32:48.129
Great job, everyone

447
00:32:48.533 --> 00:32:49.533
Thank you
