1
00:00:00,740 --> 00:00:01,700
Welcome back.

2
00:00:01,700 --> 00:00:02,780
In this lecture.

3
00:00:02,780 --> 00:00:08,900
We're going to now start working on the shop section of our GUI by adding game passes and implementing

4
00:00:08,900 --> 00:00:11,390
those game passes in our scripts.

5
00:00:11,390 --> 00:00:17,510
If you remember inside of our starting menu GUI, let me go ahead and enable UI visibility.

6
00:00:17,510 --> 00:00:24,050
We had a store frame and inside of here there are two game passes that I would like our players to buy.

7
00:00:24,050 --> 00:00:29,120
We're going to have one game pass, which will give players an upgraded golden knife that they will

8
00:00:29,120 --> 00:00:34,820
spawn with to deal more damage to zombies, and then the other game pass is going to be a faster reload

9
00:00:34,820 --> 00:00:37,070
speed for all of their guns.

10
00:00:37,070 --> 00:00:42,320
So we're going to have to script on the client when they press these buy buttons to let the server know,

11
00:00:42,320 --> 00:00:45,050
hey, we want to purchase this particular Game Pass.

12
00:00:45,050 --> 00:00:49,190
The server is going to prompt them to purchase it, and if they purchase the Game Pass, then we're

13
00:00:49,190 --> 00:00:52,760
going to give them the benefits associated with that game Pass.

14
00:00:52,760 --> 00:00:58,100
We're also going to check for when players join our game, see if they already own these game passes,

15
00:00:58,100 --> 00:01:01,070
and if they do, we'll give them those benefits.

16
00:01:01,070 --> 00:01:05,150
So let me go ahead and re hide this and disable UI visibility.

17
00:01:06,160 --> 00:01:11,530
And back in the creator dashboard, we can go ahead and create a game pass for our game.

18
00:01:11,530 --> 00:01:16,780
I'm back inside of my wave game, and we can head to the monetization tab, and there's a section for

19
00:01:16,780 --> 00:01:17,890
Game Passes.

20
00:01:17,890 --> 00:01:21,880
And inside of here I haven't created any, but we're going to create a new Game Pass.

21
00:01:22,870 --> 00:01:29,410
I'm going to name this game Pass My Golden Knife, and I'll just give it a brief description of like.

22
00:01:29,740 --> 00:01:39,310
This pass will give you access to an upgraded golden knife that deals more damage to zombies.

23
00:01:39,310 --> 00:01:44,380
We'll say something like that, and then we can also go ahead and add an image for your Game pass as

24
00:01:44,380 --> 00:01:44,920
well.

25
00:01:45,470 --> 00:01:47,210
So I just added a very basic image.

26
00:01:47,210 --> 00:01:48,020
It doesn't really matter.

27
00:01:48,020 --> 00:01:51,470
You can add whatever image you would like for your game pass, but then once you're done with that,

28
00:01:51,470 --> 00:01:53,930
we can go ahead and hit Create Pass.

29
00:01:55,830 --> 00:02:01,110
And then once we're done with that, we want to go ahead and actually select this game pass.

30
00:02:01,110 --> 00:02:03,300
And then we want to go to the sales section.

31
00:02:03,300 --> 00:02:05,430
And then we want to mark it as for sale.

32
00:02:05,430 --> 00:02:07,440
And then you can go ahead and set a price in here.

33
00:02:07,440 --> 00:02:09,210
Make sure it's a reasonable price.

34
00:02:09,210 --> 00:02:11,910
I'm just going to set mine to 99 Robux.

35
00:02:11,910 --> 00:02:13,500
We'll hit save changes.

36
00:02:14,210 --> 00:02:18,710
And now what we can go ahead and do is get the asset ID for this Game Pass.

37
00:02:18,710 --> 00:02:19,850
We'll copy that.

38
00:02:20,610 --> 00:02:25,050
And now back inside of studio, I'm going to go ahead and duplicate the badge enum.

39
00:02:25,050 --> 00:02:29,010
And instead I'm going to call this one my Game Pass enum.

40
00:02:29,010 --> 00:02:34,230
And inside of my Game Pass enum, I'm going to delete this, but instead replace it with all the game

41
00:02:34,230 --> 00:02:35,700
passes that can be purchased.

42
00:02:35,700 --> 00:02:38,430
For example, our Knife game pass.

43
00:02:38,430 --> 00:02:42,960
I'll set it equal to a table with the associated ID of that Game Pass.

44
00:02:42,960 --> 00:02:47,610
I'll paste that there, and then I'm also going to give a name for my game pass.

45
00:02:47,610 --> 00:02:50,400
I'll just call it the Knife Game Pass.

46
00:02:50,790 --> 00:02:54,810
And then we need to do the same thing for our reload game pass as well.

47
00:02:55,170 --> 00:02:58,620
Back in the Game Pass section we'll go ahead and create another new game Pass.

48
00:02:58,620 --> 00:03:01,740
I'm going to call this one faster reload.

49
00:03:02,550 --> 00:03:04,650
And I'm going to say something like.

50
00:03:05,670 --> 00:03:14,130
This pass gives you a reload buff on all the guns in your inventory.

51
00:03:14,160 --> 00:03:18,060
We'll just say something like that, and then we can go ahead and add an image to this game pass as

52
00:03:18,060 --> 00:03:18,660
well.

53
00:03:19,170 --> 00:03:22,380
Here I've just added a very simple and basic image for my game pass.

54
00:03:22,380 --> 00:03:25,020
And then we can go ahead and hit Create Pass.

55
00:03:26,140 --> 00:03:31,120
And then we'll go inside of here, go to the sales section, place it for sale and we'll add in our

56
00:03:31,120 --> 00:03:31,510
price.

57
00:03:31,510 --> 00:03:36,700
I'll just do 99 Robux, we'll hit save, and then we can go ahead and copy that asset ID.

58
00:03:37,890 --> 00:03:41,760
And now back inside of studio, we'll create another new key inside of our enum.

59
00:03:41,760 --> 00:03:44,550
We'll call this one our Reload Game Pass.

60
00:03:44,550 --> 00:03:46,290
Set that equal to a table.

61
00:03:46,290 --> 00:03:53,580
The ID is going to be the one we just copied, and the name I will call it my Reload Game Pass.

62
00:03:55,880 --> 00:04:01,160
Okay, so now what I want to do is I want to create a new script inside of server script service.

63
00:04:01,160 --> 00:04:04,970
And this script is going to be my game pass handler.

64
00:04:04,970 --> 00:04:11,450
And we're going to be handling all of the events and prompting purchases for game passes inside of our

65
00:04:11,450 --> 00:04:14,690
game, using the same common template as before.

66
00:04:14,690 --> 00:04:18,290
We'll get rid of that section and we'll get rid of that section.

67
00:04:18,290 --> 00:04:24,620
And then we can go ahead and grab the service that's responsible for prompting Game Pass purchases to

68
00:04:24,620 --> 00:04:27,470
players, which is called the marketplace Service.

69
00:04:27,470 --> 00:04:33,470
We'll get the marketplace service that's equal to game get service marketplace service.

70
00:04:33,620 --> 00:04:36,680
And then we also want to grab the player service as well.

71
00:04:39,630 --> 00:04:43,740
And what we want to go ahead and do is we want to listen for when a player joins our game.

72
00:04:43,740 --> 00:04:49,290
So when a player is added, we'll connect a function and actually we'll create a dedicated function

73
00:04:49,290 --> 00:04:49,860
for this.

74
00:04:49,860 --> 00:04:51,750
We'll call it on player added.

75
00:04:51,750 --> 00:04:57,630
And the purpose of this function is to check to see if the player owns any of the game passes that are

76
00:04:57,630 --> 00:05:00,180
inside of our Game Pass enum.

77
00:05:00,180 --> 00:05:03,060
So let's go ahead and grab Replicated storage.

78
00:05:05,400 --> 00:05:09,660
And then we can go ahead and make a reference to our Game Pass enum.

79
00:05:09,660 --> 00:05:16,110
So we'll require replicated storage, dot modules, dot enums, dot game pass enum.

80
00:05:17,310 --> 00:05:24,120
And then we can connect our on player added function to this event, which will get passed a player.

81
00:05:24,120 --> 00:05:29,190
And then we want to check if this player owns any of the game passes in our Game Pass enum.

82
00:05:29,190 --> 00:05:33,780
So we're going to loop through every single game pass inside of our Game Pass enum.

83
00:05:34,320 --> 00:05:37,500
And we want to check if this player actually owns it.

84
00:05:37,500 --> 00:05:42,480
And the way we could do that is that inside of the marketplace service there is a function called user

85
00:05:42,480 --> 00:05:48,660
owns Game Pass async and it says returns true if the player with the given user ID owns the game pass

86
00:05:48,660 --> 00:05:50,280
with the given game pass ID.

87
00:05:50,370 --> 00:05:54,720
Now, since this is an asynchronous function, we're going to have to wrap it in a p call.

88
00:05:54,720 --> 00:05:56,070
So you know the deal.

89
00:05:56,070 --> 00:05:59,550
We'll get our success and result variable and that's equal to p call.

90
00:06:00,060 --> 00:06:01,470
We'll put a lambda function in there.

91
00:06:01,470 --> 00:06:03,390
And then we're going to copy this.

92
00:06:03,630 --> 00:06:07,410
And we're going to call the user owned Game Pass async function.

93
00:06:07,410 --> 00:06:09,930
The user ID is going to be our player's user ID.

94
00:06:09,930 --> 00:06:13,560
And then the game pass ID is going to be our game pass.id.

95
00:06:14,130 --> 00:06:17,310
And then we can go ahead and return that at the end of our function.

96
00:06:18,660 --> 00:06:22,530
And we can go ahead and check if we were successful with this pickle.

97
00:06:22,530 --> 00:06:27,360
If we were not successful and an error occurred that was outside of our control, then we'll just print

98
00:06:27,360 --> 00:06:34,860
something like error while attempting to check Game Pass status for player.

99
00:06:35,790 --> 00:06:38,640
And then we can just put the error on a new line.

100
00:06:38,640 --> 00:06:43,350
So we'll do backslash n and then concatenate that with the results from our p call.

101
00:06:43,560 --> 00:06:52,800
Otherwise if we were successful and this function returned true so else if result then we can go ahead

102
00:06:52,800 --> 00:06:59,130
and set an attribute on this player to let the entire game know hey, this player has this game pass.

103
00:07:00,520 --> 00:07:03,730
So we're going to do player set attribute.

104
00:07:03,880 --> 00:07:06,340
And we're going to be using the name of this game pass.

105
00:07:06,340 --> 00:07:11,320
So we'll refer to our Game Pass and get the name and set that attribute to true on our player.

106
00:07:11,320 --> 00:07:16,480
So now any script in our game can go ahead and check to see if this player has this attribute.

107
00:07:16,480 --> 00:07:19,570
And if they have this game pass and then act accordingly.

108
00:07:20,930 --> 00:07:24,710
Now one of those game passes was my golden knife.

109
00:07:24,710 --> 00:07:27,860
Let's go ahead and actually set up our golden knife.

110
00:07:27,860 --> 00:07:32,000
If we head to server storage and go into tools, we have our golden knife right here, but we haven't

111
00:07:32,000 --> 00:07:33,740
scripted anything inside of it.

112
00:07:33,740 --> 00:07:37,760
If I change the parent to the workspace and I go and find it, here's my golden knife.

113
00:07:37,760 --> 00:07:41,330
It's literally the exact same knife, except it's made out of gold.

114
00:07:41,330 --> 00:07:46,700
And what we should do with this knife is we should basically just copy all of these scripts that were

115
00:07:46,700 --> 00:07:52,100
inside of our regular knife, including the event will copy that, paste it inside of our golden knife.

116
00:07:52,100 --> 00:07:57,500
But this time we'll update the properties for the Golden knife to be more buffed like a better knife

117
00:07:57,500 --> 00:08:00,500
to use, and it swings faster and deals more damage.

118
00:08:01,540 --> 00:08:03,820
So I'll keep the damage the same.

119
00:08:03,820 --> 00:08:08,980
But actually what I want to do is I want to increase the chance of a critical hit for my player.

120
00:08:08,980 --> 00:08:10,300
And I'm going to above this a lot.

121
00:08:10,300 --> 00:08:14,500
I'm going to make it a 55% chance of getting a critical hit.

122
00:08:14,500 --> 00:08:17,320
And I'm also going to be increasing the critical hit multiplier.

123
00:08:17,320 --> 00:08:19,810
So the minimum will bump to like 1.4.

124
00:08:19,810 --> 00:08:22,750
And then the max we can bump to like 2.2.

125
00:08:22,750 --> 00:08:25,870
And then I don't want to impose any swing cooldowns.

126
00:08:25,870 --> 00:08:28,000
So I'll set this value to zero.

127
00:08:28,000 --> 00:08:31,870
And then I also want to decrease the duration of the animation as well.

128
00:08:31,870 --> 00:08:33,970
So we'll set this to like 0.25 seconds.

129
00:08:33,970 --> 00:08:39,970
So now we have a faster swinging knife that has a better chance of dealing critical hits and dealing

130
00:08:39,970 --> 00:08:41,020
more damage.

131
00:08:41,380 --> 00:08:46,090
So I'll go ahead and move my golden knife back inside of server storage.

132
00:08:47,060 --> 00:08:51,830
And now what we can do inside of our game pass handler is we can go ahead and listen for when a player

133
00:08:51,830 --> 00:08:53,540
has a character added to them.

134
00:08:53,540 --> 00:08:59,060
And then we can go ahead and check to see if the player is on the live team, and if they are, we'll

135
00:08:59,060 --> 00:09:01,430
give them this golden knife.

136
00:09:02,230 --> 00:09:07,480
So I'll create a function I'm going to call it on character added.

137
00:09:07,840 --> 00:09:11,260
And we'll get past a character to this function.

138
00:09:11,260 --> 00:09:16,600
And then with this player inside of the on player added event, what we're going to do is we're going

139
00:09:16,600 --> 00:09:19,750
to connect to their character added event.

140
00:09:19,750 --> 00:09:21,160
So we'll connect.

141
00:09:23,050 --> 00:09:25,900
Our on character added function to this event.

142
00:09:27,330 --> 00:09:31,950
And then inside of here we're going to get the player from the players.

143
00:09:31,980 --> 00:09:33,930
Um, get player from character function.

144
00:09:33,930 --> 00:09:36,270
So player is going to be equal to players.

145
00:09:36,270 --> 00:09:37,710
Get player from character.

146
00:09:37,710 --> 00:09:39,330
Pass the character here.

147
00:09:39,780 --> 00:09:46,080
And then we can go ahead and check to see if this player has the game pass the knife game pass.

148
00:09:46,080 --> 00:09:52,500
So if player get attribute and then we're going to use Game Pass enum dot knife game Pass.

149
00:09:52,500 --> 00:09:56,970
And we're going to check to see if this player owns the knife game pass.

150
00:09:56,970 --> 00:10:01,710
And if they do then the next thing we need to check is if the player is on the alive team.

151
00:10:01,710 --> 00:10:07,980
So if player dot team is equal to the alive team, let's go ahead and grab the team service.

152
00:10:10,320 --> 00:10:16,530
So if their team is equal to teams alive, then let's go ahead and give them the golden knife.

153
00:10:16,530 --> 00:10:19,020
So we're also going to need server storage.

154
00:10:22,020 --> 00:10:23,280
Server storage.

155
00:10:24,270 --> 00:10:28,650
And we'll go ahead and make a clone of server storage tools.

156
00:10:28,650 --> 00:10:34,590
Get the Golden knife, clone that, and then we'll set the parent of that clone equal to the player's

157
00:10:34,590 --> 00:10:35,610
backpack.

158
00:10:36,870 --> 00:10:42,210
So now if I play the game, since I'm the owner of the game, I'm automatically going to have or own

159
00:10:42,210 --> 00:10:47,640
all of the game passes, which means I should spawn with a golden knife inside of my inventory.

160
00:10:47,640 --> 00:10:49,500
So let's go ahead and play the game.

161
00:10:50,840 --> 00:10:56,420
And what I'm going to do is I'm actually going to head over to the player service and look at my character.

162
00:10:56,420 --> 00:11:02,390
And unfortunately, we don't have any attributes set on me, which is kind of interesting.

163
00:11:02,660 --> 00:11:07,400
If I spawn it to the map, I did not get my golden knife, which is strange.

164
00:11:07,400 --> 00:11:09,590
So let's go ahead and figure out why that's the case.

165
00:11:11,150 --> 00:11:14,090
I think it could be because we're testing in studio.

166
00:11:14,120 --> 00:11:19,040
The player might be added before the server is able to listen to the player added event.

167
00:11:19,040 --> 00:11:24,500
So just as a little bit of extra security, what I'm going to do is I'm going to loop through every

168
00:11:24,500 --> 00:11:25,790
player that's already in the game.

169
00:11:25,790 --> 00:11:28,670
So we'll do players, get players.

170
00:11:29,160 --> 00:11:35,640
And that way, if there's any players in the game that weren't able to be listened to because the player

171
00:11:35,640 --> 00:11:40,290
added event did not have this function connected to it yet, then we can go ahead and call our on player

172
00:11:40,290 --> 00:11:44,490
added function and pass our player to it.

173
00:11:45,130 --> 00:11:49,780
And then one last thing I want to make a minor change to is that since this is going to be yielding

174
00:11:49,780 --> 00:11:56,470
right here, I don't want to halt the main thread of execution and have it stuck yielding.

175
00:11:56,470 --> 00:12:01,660
So I'm actually going to spawn in a new thread.

176
00:12:02,600 --> 00:12:03,860
This code right here.

177
00:12:03,860 --> 00:12:05,180
So I'll do that.

178
00:12:05,180 --> 00:12:10,820
So that way for every single game pass we're checking, we are doing them all instantaneously at the

179
00:12:10,820 --> 00:12:12,170
same time for a player.

180
00:12:12,170 --> 00:12:18,500
Instead of having to sequentially go from one game pass to the next game pass, having to wait and yield

181
00:12:18,500 --> 00:12:21,830
for this function to return to us a result.

182
00:12:21,830 --> 00:12:23,690
So we're going to try it this way.

183
00:12:23,750 --> 00:12:26,060
And now if we go and play test the game.

184
00:12:27,690 --> 00:12:30,840
Hopefully if we go and take a look at our player.

185
00:12:31,660 --> 00:12:33,550
We still don't have the attributes.

186
00:12:33,550 --> 00:12:34,720
Very weird.

187
00:12:36,020 --> 00:12:40,910
Okay, so I found out what the issue was, which is a very strange issue.

188
00:12:40,910 --> 00:12:48,110
If I go to my knife game pass and I copy the asset ID directly from here, this is the ID that it gives

189
00:12:48,110 --> 00:12:48,530
me, right?

190
00:12:48,530 --> 00:12:50,990
We pasted it into our module script.

191
00:12:50,990 --> 00:12:58,430
However, if I go back and I copy the asset ID from here, take a look at this.

192
00:12:58,430 --> 00:13:01,010
The ID is completely different.

193
00:13:01,790 --> 00:13:04,040
And this is the ID that actually works.

194
00:13:04,040 --> 00:13:06,470
The other IDs were not working.

195
00:13:06,800 --> 00:13:08,270
Why this is the case?

196
00:13:08,270 --> 00:13:09,050
I have no idea.

197
00:13:09,050 --> 00:13:10,610
It must be a very weird bug.

198
00:13:10,610 --> 00:13:18,050
So what I advise for you to do is to go back to your game passes and copy the asset ID from here and

199
00:13:18,050 --> 00:13:19,700
not from here.

200
00:13:19,700 --> 00:13:23,060
I don't know why it's giving me two different asset ID numbers.

201
00:13:23,060 --> 00:13:29,120
That's very weird, but go ahead and copy your asset IDs from here and then it should be working.

202
00:13:29,970 --> 00:13:33,060
Okay, I just updated the two IDs for my game pass.

203
00:13:33,060 --> 00:13:35,220
They're completely different from the other ones I copied.

204
00:13:35,250 --> 00:13:43,680
I don't know why Roblox moment, but now if we go and play test our game and then we go back to my player,

205
00:13:43,680 --> 00:13:44,460
there we go.

206
00:13:44,460 --> 00:13:50,010
Now it says that I own both the knife game pass and the reload game pass, and if I go and play test

207
00:13:50,010 --> 00:13:52,080
my game, there we go.

208
00:13:52,080 --> 00:13:54,900
I get spawned with the Golden knife.

209
00:13:54,900 --> 00:13:55,800
Very cool.

210
00:13:57,420 --> 00:14:03,300
Okay, the next game pass that I want to script for is going to be the faster reload game pass.

211
00:14:03,300 --> 00:14:08,430
And this one's going to be a little bit trickier, because what we need to do is we need to update the

212
00:14:08,430 --> 00:14:13,530
properties module script for our gun on both the client and on the server.

213
00:14:13,530 --> 00:14:18,870
So that means if the server finds that a player has a gun in their inventory, the server needs to update

214
00:14:18,870 --> 00:14:25,050
the reload duration on the server side and then tell the client to update the reload duration on their

215
00:14:25,050 --> 00:14:29,940
side as well, because again, the module scripts ones on the server, ones on the client, they're

216
00:14:29,940 --> 00:14:33,630
going to be two different module scripts that both need to be updated.

217
00:14:34,510 --> 00:14:40,840
So in order to account for that, we can use the exact same gun event that the guns use and instead

218
00:14:40,840 --> 00:14:45,880
fire to a client to a specific gun that needs to be updated with its reload duration.

219
00:14:45,880 --> 00:14:49,270
And then we can listen from the local script that is inside of our gun.

220
00:14:49,270 --> 00:14:53,410
When the server tells us to update the reload duration, we'll do that on the client side, and then

221
00:14:53,410 --> 00:14:57,010
the server updates the reload duration on the server side as well.

222
00:14:57,690 --> 00:15:02,430
So that means what I want to do is I want to check if my player.

223
00:15:02,460 --> 00:15:03,600
Get attribute.

224
00:15:03,600 --> 00:15:06,660
They have the faster reload.

225
00:15:06,660 --> 00:15:08,250
So reload game pass.

226
00:15:08,250 --> 00:15:14,460
If they own that game pass then we want to listen for when a child is added to the player's character.

227
00:15:14,460 --> 00:15:20,550
And the reason for that is we need to check if that child is a gun, and if it is, we want to tell

228
00:15:20,550 --> 00:15:25,950
the client to update the reload duration property for that particular gun.

229
00:15:25,950 --> 00:15:27,060
So.

230
00:15:28,370 --> 00:15:31,010
When the character has a child added to them.

231
00:15:31,010 --> 00:15:35,570
We're going to connect a function to this which is going to be on, child added.

232
00:15:35,570 --> 00:15:40,010
So we'll create a new function, call it on, child added.

233
00:15:40,010 --> 00:15:44,870
We'll get past the child and we need to check to see if this child is a tool.

234
00:15:44,870 --> 00:15:50,300
So if this child is not a tool, is a tool then we're going to return.

235
00:15:51,190 --> 00:15:55,480
If this child is a tool, but it's not a gun, then we're also going to return.

236
00:15:55,480 --> 00:16:03,010
So if not child get attribute gun type then we also need to return.

237
00:16:03,010 --> 00:16:09,340
And then another thing we need to keep track of is if we've already buffed the reload duration for this

238
00:16:09,340 --> 00:16:10,330
particular gun.

239
00:16:10,330 --> 00:16:13,600
So what we can go ahead and do is set an attribute on this child.

240
00:16:13,600 --> 00:16:18,670
Once the server has a buffed the reload duration and set to say something like it's already been reload

241
00:16:18,670 --> 00:16:19,030
buffed.

242
00:16:19,030 --> 00:16:24,610
So that way when the player equips the tool and then re equips it, we don't accidentally buff the reload

243
00:16:24,610 --> 00:16:26,350
duration again on the gun.

244
00:16:26,680 --> 00:16:30,970
So what we can go ahead and do is set an attribute on this gun.

245
00:16:30,970 --> 00:16:33,820
And we're going to call it something like reload buffed.

246
00:16:35,670 --> 00:16:36,810
And we'll set that to true.

247
00:16:36,810 --> 00:16:42,900
And that way we can go ahead and check if this child already has the attribute of reload buffed.

248
00:16:42,900 --> 00:16:45,540
And if it does, then we're going to return.

249
00:16:45,870 --> 00:16:50,340
Otherwise we can go ahead and get the player that has this gun equipped.

250
00:16:50,340 --> 00:16:54,570
So we're going to do players get player from character.

251
00:16:54,570 --> 00:16:56,970
And that's going to be the parent of this child.

252
00:16:58,410 --> 00:17:01,440
And then we're going to grab the properties for this gun.

253
00:17:01,440 --> 00:17:03,060
So we'll require.

254
00:17:03,760 --> 00:17:06,340
Child that properties since it's a gun.

255
00:17:08,000 --> 00:17:11,960
And then we can go ahead and update the properties reload duration.

256
00:17:11,960 --> 00:17:18,620
And since we want to make the reload duration 35% faster, let's go ahead and define a constant up here.

257
00:17:20,250 --> 00:17:23,010
And I'll call this constant reload percent.

258
00:17:23,010 --> 00:17:25,350
And we're going to set it to 0.65.

259
00:17:25,350 --> 00:17:30,210
And then we can go ahead and multiply our reload duration by this value to make the reload duration

260
00:17:30,210 --> 00:17:31,710
35% faster.

261
00:17:31,710 --> 00:17:35,430
So we'll do times equal reload percent.

262
00:17:35,640 --> 00:17:42,450
And then here we could use the gun event that's inside of replicated storage to tell this player, hey,

263
00:17:42,450 --> 00:17:47,040
you need to update the property for this particular gun on your side as well.

264
00:17:47,160 --> 00:17:50,940
So let's go ahead and make a reference to that gun event.

265
00:17:50,940 --> 00:17:53,910
So replicated storage dot remotes dot gun event.

266
00:17:55,270 --> 00:18:01,090
And I want to hop into my gun comms enum, and then I want to create a section for actions to be given

267
00:18:01,090 --> 00:18:02,350
to the client.

268
00:18:02,500 --> 00:18:05,710
And this action I'm going to call it Update property.

269
00:18:05,710 --> 00:18:10,900
So that way the client knows to update a property on their gun and then back inside of our game pass

270
00:18:10,900 --> 00:18:17,710
handler we can go ahead and grab the gun comms enum, so we'll require replicated storage, dot modules,

271
00:18:17,710 --> 00:18:19,750
dot enums, dot gun comms enum.

272
00:18:20,020 --> 00:18:23,680
And then we'll use the gun event fire to this particular player.

273
00:18:23,680 --> 00:18:25,180
So we'll pass the player here.

274
00:18:25,180 --> 00:18:32,110
We'll give them the action which is going to be gun comms enum dot two client dot update property.

275
00:18:32,410 --> 00:18:37,150
And we also want to let them know which particular gun they need to update.

276
00:18:37,150 --> 00:18:41,710
And that's because if the player has multiple different guns, then all of those guns are going to be

277
00:18:41,710 --> 00:18:43,270
listening to this event.

278
00:18:43,270 --> 00:18:48,070
So we only want to fire this to a particular gun in their inventory.

279
00:18:48,070 --> 00:18:53,290
And the easiest way for us to do that is simply just to pass the tool itself to the player.

280
00:18:53,290 --> 00:18:56,740
So the player knows exactly which gun to update.

281
00:18:58,060 --> 00:19:01,000
And then we could pass the property.

282
00:19:01,000 --> 00:19:06,220
They need to update on that gun, which would be the reload duration, and then we can tell them what

283
00:19:06,220 --> 00:19:09,370
value we would like them to set that reload duration to.

284
00:19:09,370 --> 00:19:13,330
And that's just going to be equal to the reload duration that is on the server.

285
00:19:15,200 --> 00:19:19,250
But now what we need to do is we need to hop into one of the local scripts for our gun.

286
00:19:19,250 --> 00:19:26,750
I'll just do it for the AR, and then we'll go down to the handler section, and we want to listen for

287
00:19:26,750 --> 00:19:29,510
when our gun event is fired on the client.

288
00:19:29,510 --> 00:19:33,890
So on client event we'll connect a function to this.

289
00:19:34,310 --> 00:19:37,280
And the server is going to be passing to us the action.

290
00:19:37,280 --> 00:19:40,820
And then they're going to pass us the particular gun they want us to update.

291
00:19:40,820 --> 00:19:43,610
So we'll call this passed gun the property.

292
00:19:43,610 --> 00:19:46,580
And then the value we want to update to that property.

293
00:19:47,290 --> 00:19:54,040
So first thing we want to check is if this passed gun the server is giving to us is equal to the same

294
00:19:54,040 --> 00:19:56,050
gun that this local script is in.

295
00:19:56,050 --> 00:20:02,500
So if the passed gun is not equal to the gun that's referred to in this local script, then we're just

296
00:20:02,500 --> 00:20:05,380
going to return and ignore it for this particular gun.

297
00:20:05,380 --> 00:20:08,440
Otherwise we can check if the action is equal to the gun.

298
00:20:08,440 --> 00:20:10,930
Comms enum of two client.

299
00:20:11,570 --> 00:20:17,390
Dot update property, and if it is, then we can just simply refer to the properties inside of our gun

300
00:20:17,390 --> 00:20:22,400
and update this particular property the server wants us to update with this new value.

301
00:20:22,950 --> 00:20:29,430
And just like that, we should now have implemented a reload buff to all of the guns in our game.

302
00:20:29,670 --> 00:20:35,880
So what I'm going to do is I'm going to copy this new local script and put it inside of all of my guns,

303
00:20:35,880 --> 00:20:39,900
and I'll go ahead and get rid of the old local script for my guns.

304
00:20:39,900 --> 00:20:43,860
So we'll just delete that old one, get rid of that one, that one.

305
00:20:43,860 --> 00:20:45,660
Delete, delete and delete.

306
00:20:46,830 --> 00:20:52,200
And then just to quickly test this out, I'm going to copy the R and put it inside of the starter pack.

307
00:20:52,530 --> 00:20:58,080
And then to try to make this reload duration as prominent as possible.

308
00:20:58,080 --> 00:21:00,810
So we can tell to see if the reload buff got applied to us.

309
00:21:00,810 --> 00:21:03,630
I'm going to set the reload percent to like one.

310
00:21:03,630 --> 00:21:06,540
So our reload duration should be like 90% faster.

311
00:21:06,540 --> 00:21:08,130
So let's go ahead and see if that worked.

312
00:21:08,130 --> 00:21:09,420
If we play the game.

313
00:21:11,160 --> 00:21:13,680
And then we go and hop into the game.

314
00:21:14,640 --> 00:21:17,850
I got my assault rifle, and if I shoot and then reload.

315
00:21:18,630 --> 00:21:21,840
Yeah, you can see our reload duration was much faster.

316
00:21:21,870 --> 00:21:22,890
Let's try that again.

317
00:21:23,460 --> 00:21:26,670
And as you can see, look how fast reload is.

318
00:21:28,020 --> 00:21:30,390
Obviously that's a reload duration.

319
00:21:30,390 --> 00:21:32,310
That's too fast for my taste.

320
00:21:32,520 --> 00:21:41,100
I much prefer the 35% buff, but at least we know that the reload buff is actually working for any players

321
00:21:41,100 --> 00:21:45,150
in our game that have the Reload Buff game pass.

322
00:21:46,210 --> 00:21:52,930
So the next thing that we need to go ahead and do is we need to script the functionality for the player

323
00:21:52,930 --> 00:21:58,960
to interact with the GUI, to buy game passes, and then we need to listen on the server when the player

324
00:21:58,960 --> 00:22:00,790
actually purchases those game pass.

325
00:22:00,790 --> 00:22:06,220
And if they do purchase it, we need to set those attributes on our player to true in real time, because

326
00:22:06,220 --> 00:22:10,720
we don't want to force our player to have to rejoin the game in order to get their benefits.

327
00:22:11,360 --> 00:22:15,170
So let's go ahead and go back into the local script for our starting menu.

328
00:22:15,200 --> 00:22:16,190
We'll open that up.

329
00:22:16,950 --> 00:22:23,280
And then we want to go ahead and listen to all the stuff that's going to be inside of our shop.

330
00:22:23,280 --> 00:22:28,050
Specifically, when the player presses the shot button, we want to display the shop onto their screen,

331
00:22:28,050 --> 00:22:30,870
and when they press the close button, we want to close the shop.

332
00:22:30,870 --> 00:22:36,480
And if they press one of the buy buttons for one of the game passes, then we'll fire to the server.

333
00:22:36,480 --> 00:22:42,240
Hey, we want to purchase this particular game Pass, so let's actually go ahead and grab the Game Pass

334
00:22:42,240 --> 00:22:47,790
enum here in this local script will require and get and replicated storage modules dot enums dot game

335
00:22:47,790 --> 00:22:48,780
pass enum.

336
00:22:49,900 --> 00:22:55,870
And then we'll go down to our handlers section, and we'll make a little section here for listening

337
00:22:55,900 --> 00:22:57,850
to events for our shop.

338
00:22:58,000 --> 00:23:03,280
And I want to kind of segregate it and be able to collapse it and hide it, just to make my script more

339
00:23:03,280 --> 00:23:03,910
organized.

340
00:23:03,910 --> 00:23:06,700
And the easiest way to do that would be to create a new scope.

341
00:23:07,210 --> 00:23:11,980
And the easiest way to create a new scope would just be to type du and then hit enter.

342
00:23:12,280 --> 00:23:16,840
And what I've done right here is just made a little new scope that I'm able to collapse.

343
00:23:16,840 --> 00:23:19,930
And any variables I make inside of this scope.

344
00:23:19,930 --> 00:23:25,810
For example, this is a variable right here since it's local to this particular scope right here, I

345
00:23:25,810 --> 00:23:29,380
can't access the example variable outside of that scope.

346
00:23:30,090 --> 00:23:34,950
So inside of my little scope, I want to listen for when my shot button is activated.

347
00:23:35,640 --> 00:23:41,370
And when that happens, we want to go ahead and make the shot frame visible on the player screen.

348
00:23:42,100 --> 00:23:45,460
And then inside of our shop frame we have a close button.

349
00:23:45,700 --> 00:23:49,720
We want to listen for when that is activated and when the player presses that.

350
00:23:49,720 --> 00:23:53,470
We'll go ahead and refer to our shop frame and set visible back to false.

351
00:23:54,490 --> 00:23:59,440
And then inside of the shop frame, we have our container frame that contains all of the different frames

352
00:23:59,440 --> 00:24:00,640
for the game passes.

353
00:24:00,640 --> 00:24:05,710
For example, one of them is going to be our faster reload frame, and inside of there we have a buy

354
00:24:05,710 --> 00:24:06,460
button.

355
00:24:06,550 --> 00:24:10,660
And we'll go ahead and listen for when that is activated and when it is.

356
00:24:10,690 --> 00:24:15,490
This is where we could fire an event to the server to prompt a purchase to us.

357
00:24:15,760 --> 00:24:22,750
So inside of replicated storage, I have another remote event inside of the GUI folder called Buy Game

358
00:24:22,750 --> 00:24:23,440
Pass.

359
00:24:23,530 --> 00:24:25,750
Let's go ahead and make a reference to that real quick.

360
00:24:26,780 --> 00:24:28,340
I'll create a new variable.

361
00:24:28,340 --> 00:24:34,280
I'll call it Game Pass Event and that's replicated storage, dot remotes, dot guy dot game pass or

362
00:24:34,280 --> 00:24:35,390
by Game Pass.

363
00:24:36,480 --> 00:24:42,810
And then we can go ahead and use this Game Pass event and fire to the server.

364
00:24:43,080 --> 00:24:49,110
And then we can tell them which game pass we would like to purchase by passing the ID of the Game Pass.

365
00:24:49,110 --> 00:24:50,940
So we'll use our Game Pass enum.

366
00:24:51,760 --> 00:24:54,310
And we'll use for this case.

367
00:24:54,310 --> 00:24:58,030
It's going to be the reload game pass and we'll just pass the ID to the server.

368
00:24:58,740 --> 00:25:00,960
And I'm going to copy this, paste this here.

369
00:25:00,960 --> 00:25:05,730
And we want to do the same thing for the Golden Knife Game Pass.

370
00:25:05,730 --> 00:25:09,870
And this time we're going to tell the server that we would like to purchase the Knife Game Pass.

371
00:25:09,870 --> 00:25:14,610
So now what we need to do on the server is listen for when this Game Pass event is fired.

372
00:25:14,610 --> 00:25:19,140
And when the player tells us they want to purchase a game pass, we're going to prompt a purchase to

373
00:25:19,140 --> 00:25:19,560
them.

374
00:25:20,460 --> 00:25:22,740
The backhand side of our game pass handler.

375
00:25:22,740 --> 00:25:27,930
Well, we can go ahead and do is we can listen for when our Game Pass event is fired.

376
00:25:27,930 --> 00:25:30,660
And that means we're actually going to need to make a variable for it.

377
00:25:30,660 --> 00:25:37,830
So we'll get our Game Pass event that's replicated storage dot events or remotes GUI dot.

378
00:25:38,800 --> 00:25:39,970
Game pass or buy.

379
00:25:40,000 --> 00:25:40,600
Game pass.

380
00:25:40,600 --> 00:25:41,290
There we go.

381
00:25:42,420 --> 00:25:49,530
And then Game Pass event will listen for on server event, connect a function, get the player and then

382
00:25:49,530 --> 00:25:52,770
the ID of the game pass they want to purchase.

383
00:25:53,570 --> 00:25:58,580
And then what we want to go ahead and do is we want to loop through all of the game passes in our enum

384
00:25:58,580 --> 00:26:05,180
and check to see if the ID the player passed to us actually belongs to one of the game passes in our

385
00:26:05,180 --> 00:26:06,290
Game Pass enum.

386
00:26:06,290 --> 00:26:13,970
So for every single game pass inside of our Game Pass enum, what we want to do is we want to check

387
00:26:13,970 --> 00:26:21,230
if this game pass ID, so if game pass ID if it's not equal to this game passes.

388
00:26:22,270 --> 00:26:25,960
Uh, ID then we'll just continue to the next game pass.

389
00:26:26,320 --> 00:26:32,290
Otherwise, if we found a matching game pass, then we can go ahead and use the marketplace service.

390
00:26:32,290 --> 00:26:36,310
And there's a function in there called Prompt Game Pass purchase.

391
00:26:36,310 --> 00:26:40,990
And we need to pass the player and then the ID for the game pass.

392
00:26:40,990 --> 00:26:43,180
So we'll pass our player here.

393
00:26:43,630 --> 00:26:46,720
And then we can go ahead and pass the game pass.id.

394
00:26:47,830 --> 00:26:51,310
And once we do that, we can go ahead and just break out of this loop because there's no reason for

395
00:26:51,310 --> 00:26:55,630
us to continue looping through the other game passes because we found the one that the player wanted

396
00:26:55,630 --> 00:26:56,560
to purchase.

397
00:26:56,890 --> 00:27:01,810
So when we call this function on the client side, a little pop up window is going to appear to tell

398
00:27:01,810 --> 00:27:03,610
them to purchase the Game Pass.

399
00:27:03,610 --> 00:27:08,560
And if they purchase it, then it's going to notify us on the server and there's an event for that.

400
00:27:09,070 --> 00:27:15,310
There is an event inside of the marketplace service called Prompt Game Pass Purchase finished.

401
00:27:15,310 --> 00:27:18,580
So we're going to connect a function to this.

402
00:27:19,130 --> 00:27:25,520
And this function is going to be passed to the player what the game pass ID was and whether or not they

403
00:27:25,520 --> 00:27:27,080
purchased the game pass.

404
00:27:27,080 --> 00:27:33,710
So we'll get the player the ID of the game pass, and then it'll tell us whether or not it was purchased.

405
00:27:35,020 --> 00:27:40,030
So now what we can go ahead and do is we can again loop through all of the game passes in our Game Pass

406
00:27:40,030 --> 00:27:40,660
enum.

407
00:27:41,560 --> 00:27:47,470
And if this ID is not equal to this game pass ID, then we'll just continue looping to the next game

408
00:27:47,470 --> 00:27:51,370
pass until we eventually find which game pass they purchased.

409
00:27:51,370 --> 00:27:56,140
And if we've confirmed that they've purchased the Game Pass, then we can go ahead and set an attribute

410
00:27:56,140 --> 00:27:58,900
on this player for this particular game Pass.

411
00:27:58,900 --> 00:28:04,600
And we'll just use the Game Pass dot name and set that equal to true.

412
00:28:04,600 --> 00:28:08,530
And of course we only want to do this if they actually purchased the Game Pass.

413
00:28:08,530 --> 00:28:14,020
So if they did not purchase the Game Pass then we're just going to return and ignore this player.

414
00:28:14,020 --> 00:28:18,550
Otherwise if they did purchase the game pass, then we're going to set that attribute on our player

415
00:28:18,550 --> 00:28:19,210
to true.

416
00:28:19,210 --> 00:28:24,670
And then because we're setting that attribute on them, any time they spawn into the game, we're going

417
00:28:24,670 --> 00:28:29,020
to be giving them their golden knife or any time they have a gun added to their inventory.

418
00:28:29,020 --> 00:28:33,400
If it's the reload game pass, we're going to be buffing the reload for them.

419
00:28:33,930 --> 00:28:37,680
So let's go ahead and test to see if all of this is working.

420
00:28:38,220 --> 00:28:39,750
We'll go and play test our game.

421
00:28:41,110 --> 00:28:44,380
And we should be able to open up our store if we hit this button.

422
00:28:44,410 --> 00:28:45,070
There we go.

423
00:28:45,070 --> 00:28:46,120
Our store is open.

424
00:28:46,120 --> 00:28:48,400
We have our golden knife and our fast reload.

425
00:28:48,400 --> 00:28:51,700
I didn't upload any images for these two frames.

426
00:28:51,700 --> 00:28:56,590
If you want to go ahead and insert your own images inside of the GUI, you're more than welcome to do

427
00:28:56,590 --> 00:28:57,040
that.

428
00:28:57,040 --> 00:29:01,150
But we want to test if the server is going to prompt us to purchase the Game Pass.

429
00:29:01,150 --> 00:29:02,650
So if I hit this buy button.

430
00:29:03,630 --> 00:29:04,200
There we go.

431
00:29:04,200 --> 00:29:05,520
It says you already own this item.

432
00:29:05,520 --> 00:29:06,840
Your account has not been charged.

433
00:29:06,840 --> 00:29:10,500
Which is, of course, what I would expect because I already own the Game pass.

434
00:29:10,500 --> 00:29:14,610
But as you can see, it is working when we press these buy buttons.

435
00:29:16,350 --> 00:29:17,490
You already own this item.

436
00:29:17,490 --> 00:29:21,420
Your account has not been charged, so we're not able to purchase them because it's like, what are

437
00:29:21,420 --> 00:29:21,690
you doing?

438
00:29:21,690 --> 00:29:23,760
You already you already own the game pass, right?

439
00:29:25,390 --> 00:29:31,870
And if we go and playtest our game, I've got my golden knife ready to slay some zombies.

440
00:29:31,870 --> 00:29:34,300
So let's go ahead and actually test out our golden knife.

441
00:29:35,110 --> 00:29:37,570
This thing should be a lot better than the regular knife.

442
00:29:37,570 --> 00:29:42,730
So if I stab this guy, hopefully I get a critical hit here.

443
00:29:45,490 --> 00:29:48,340
It also swings a lot faster than the regular knife.

444
00:29:48,340 --> 00:29:52,090
So if I swing the regular knife, that's how fast I can swing it.

445
00:29:52,090 --> 00:29:58,540
And then with the golden knife, as you can see, I can swing it a lot faster and it does deal a lot

446
00:29:58,540 --> 00:29:59,680
more damage.

447
00:29:59,680 --> 00:30:00,220
Yeah.

448
00:30:03,280 --> 00:30:07,180
Of course, you can further buff the damage and the critical hit rate of this golden knife.

449
00:30:07,180 --> 00:30:10,180
Do whatever you want, change your game however you want.

450
00:30:10,180 --> 00:30:13,060
It's totally up to your creative preference.

451
00:30:15,510 --> 00:30:17,790
Let's go ahead and clear out all these zombies.

452
00:30:21,300 --> 00:30:23,850
I got a one hit shot on that zombie right there.

453
00:30:29,430 --> 00:30:32,250
Oh, it looks like I forgot to reset the value back to one.

454
00:30:32,250 --> 00:30:33,270
So it says game over.

455
00:30:33,270 --> 00:30:34,230
You win.

456
00:30:35,330 --> 00:30:37,910
So I need to actually go back.

457
00:30:37,910 --> 00:30:38,630
And it killed me.

458
00:30:38,630 --> 00:30:45,800
I need to go back to my game handler and make sure I actually reset the total waves back to 11.

459
00:30:45,800 --> 00:30:51,890
And then I'm going to reset the intermission back to its regular value of 60, and then the start intermission

460
00:30:51,890 --> 00:30:53,360
back to its value of 30.

461
00:30:55,310 --> 00:30:55,940
Otherwise.

462
00:30:55,940 --> 00:31:00,560
That is how we can implement game passes into our game.

463
00:31:00,560 --> 00:31:04,610
I hope you're enjoying the project so far and I'll see you in the next lecture.
