1
00:00:00,510 --> 00:00:05,370
Alrighty, now we get to move on to our local script for the SCP 294 GUI.

2
00:00:05,400 --> 00:00:10,200
This should be pretty straightforward, as you've likely interacted with GUI and GUI events in the past.

3
00:00:10,200 --> 00:00:14,160
And if you've been in my previous course, you'll be familiar with GUIs and their events.

4
00:00:14,310 --> 00:00:18,900
This guy in particular is going to be the one that contains the keyboard, as well as the display to

5
00:00:18,900 --> 00:00:21,090
show what the player is typing for their drink.

6
00:00:21,090 --> 00:00:25,470
So if I go ahead and enable visibility here, we're just going to have this on their screen.

7
00:00:25,470 --> 00:00:30,000
And whenever they type something in, we're going to show that text here on this little screen.

8
00:00:30,760 --> 00:00:35,110
So inside of our local script for the GUI, we're just going to need three services.

9
00:00:35,110 --> 00:00:37,480
One is going to be the player service.

10
00:00:39,430 --> 00:00:43,360
We're going to need the sound service so we could get access to the guy.

11
00:00:43,390 --> 00:00:44,320
Sounds.

12
00:00:45,640 --> 00:00:50,350
We're also going to need replicated storage as well, so we can get access to some of those assets in

13
00:00:50,350 --> 00:00:50,860
there.

14
00:00:53,480 --> 00:00:55,850
And then let's go ahead and fill out some variables.

15
00:00:55,880 --> 00:00:58,190
I first want to get access to our drink class.

16
00:00:58,190 --> 00:01:01,400
This is going to be our local drink class that exists on the client.

17
00:01:01,400 --> 00:01:03,770
So we're going to require within replicated storage.

18
00:01:03,770 --> 00:01:07,670
We're going to wait for the SCP 294 assets folder to replicate.

19
00:01:07,670 --> 00:01:11,210
And we're going to require our drink class for the client.

20
00:01:11,840 --> 00:01:15,650
And then we're also going to have a reference to our request drink event.

21
00:01:16,630 --> 00:01:22,510
And we'll have that in replicated storage, same folder, and we'll wait for the request remote function.

22
00:01:23,380 --> 00:01:27,040
We'll have a reference to the guy itself, which is just script dot parent.

23
00:01:27,610 --> 00:01:31,660
We'll have a reference to the local player which is just players dot local player.

24
00:01:31,900 --> 00:01:35,950
And then we'll also have a reference to the local character of this player.

25
00:01:35,950 --> 00:01:38,110
So we can just do player dot character.

26
00:01:38,110 --> 00:01:44,950
Or if the player's character hasn't been added yet, we can do or player dot character added and we'll

27
00:01:44,950 --> 00:01:49,480
wait for this event and this event will return to us the character and store it in our variable.

28
00:01:49,660 --> 00:01:54,520
I want to have a reference to that display text or the output box that is in our guy.

29
00:01:54,550 --> 00:01:59,110
So I'll call this output box and it's inside of our guy.

30
00:01:59,110 --> 00:02:02,470
We're going to wait for the frame to replicate just in case.

31
00:02:02,470 --> 00:02:04,810
We're going to wait for the image label in there.

32
00:02:04,810 --> 00:02:09,850
And inside this image label there is a frame called output or a text label called output.

33
00:02:09,850 --> 00:02:11,920
And that's where we're going to put our text.

34
00:02:12,340 --> 00:02:15,430
And I want to refer to all the buttons that are inside of our GUI.

35
00:02:15,430 --> 00:02:19,180
And we can just do that by doing GUI, dot frame, dot image label.

36
00:02:19,180 --> 00:02:22,450
And we'll get every single child that is in our image label.

37
00:02:22,450 --> 00:02:23,920
So inside of our GUI.

38
00:02:23,950 --> 00:02:27,070
Here we have a bunch of buttons.

39
00:02:27,070 --> 00:02:32,710
In each of these buttons are for all the numbers and all of the letters that we could input into our

40
00:02:32,710 --> 00:02:33,580
drink machine.

41
00:02:33,580 --> 00:02:37,810
So that means we're going to have to connect a function to every single one of these text buttons.

42
00:02:37,810 --> 00:02:41,560
And, you know, take their letter and put that in the output box.

43
00:02:42,070 --> 00:02:44,860
I also want to have a reference to the click sound.

44
00:02:45,670 --> 00:02:46,150
For.

45
00:02:46,150 --> 00:02:50,770
When we click a button on our guy, we can play that click sound so it's in sound service.

46
00:02:50,770 --> 00:02:57,730
We'll wait for the SCP 294 sounds to replicate, wait for the guy folder, and we're going to wait for

47
00:02:57,730 --> 00:02:59,230
the button sound.

48
00:03:00,000 --> 00:03:07,710
And then I'm going to create two variables, one called original walk speed and one called original

49
00:03:07,710 --> 00:03:09,090
jump height.

50
00:03:09,210 --> 00:03:15,060
And we're going to store these in these variables because when the player opens the GUI on their screen,

51
00:03:15,060 --> 00:03:18,870
I want to set the player's walk speed to zero and their jump height to zero.

52
00:03:18,900 --> 00:03:22,200
That way they can't move while they have the GUI open.

53
00:03:22,200 --> 00:03:27,180
And then once they close the GUI, we'll set their walk speed and their jump height back to their original

54
00:03:27,180 --> 00:03:30,030
so we can set this equal to the local character.

55
00:03:30,390 --> 00:03:32,520
I'm going to wait for the humanoid.

56
00:03:33,170 --> 00:03:35,960
And we're going to get the walk speed.

57
00:03:36,080 --> 00:03:39,320
And then we could do the same thing for the local character.

58
00:03:40,220 --> 00:03:42,890
Humanoid dot jump height.

59
00:03:43,340 --> 00:03:48,020
And it should be jump height unless you have a different setting set inside of starter player.

60
00:03:48,020 --> 00:03:52,610
So inside of starter player here there's a section called character jump settings.

61
00:03:52,610 --> 00:03:57,350
Typically before they had it where you had to use a property called jump power.

62
00:03:57,350 --> 00:04:00,770
But I believe now they have changed it to use a default called jump height.

63
00:04:00,770 --> 00:04:05,180
But if you still have this enabled, then instead the value is going to be jump power.

64
00:04:05,180 --> 00:04:10,070
So you'll have to change this to jump power instead of jump height.

65
00:04:10,250 --> 00:04:13,010
But I'm just going to use the default of jump height.

66
00:04:13,750 --> 00:04:16,420
And actually I want to have a reference to the other event as well.

67
00:04:16,450 --> 00:04:17,530
Our comms event.

68
00:04:17,530 --> 00:04:23,830
So replicated storage get our assets folder and we'll wait for the communication remote event to replicate.

69
00:04:24,600 --> 00:04:28,140
And then I'm going to use one variable as our debounce.

70
00:04:28,500 --> 00:04:33,030
And this debounce is going to be for when we request to dispense a drink, we're going to output the

71
00:04:33,030 --> 00:04:34,440
text like dispensing.

72
00:04:34,440 --> 00:04:38,610
And we don't want the player to be able to input any more text into the display.

73
00:04:38,610 --> 00:04:43,500
So we'll make sure to enable a Debounce and then disable it once the player gets their drink.

74
00:04:43,770 --> 00:04:46,980
Now for our GUI, I want to have a few functions.

75
00:04:46,980 --> 00:04:50,610
One function I'll have to close the GUI.

76
00:04:50,940 --> 00:04:56,490
I'm going to have a function for every single button or text button inside of our guy, so I'll just

77
00:04:56,490 --> 00:04:58,410
call it on button clicked.

78
00:04:59,950 --> 00:05:04,420
And then I want to have a function for dispensing the drink.

79
00:05:04,420 --> 00:05:06,160
So we'll call it dispense drink.

80
00:05:08,550 --> 00:05:14,730
And then one last function we'll need is I'm going to call it on child added to backpack.

81
00:05:14,820 --> 00:05:19,560
And this is going to listen for when a child or a tool gets added to the player's backpack.

82
00:05:19,560 --> 00:05:24,780
And if it's a drink cup then we're going to create or get a new drink object for our drink class.

83
00:05:25,550 --> 00:05:29,930
Now some handlers will need of course is going to be for the comms event.

84
00:05:30,760 --> 00:05:35,290
And on client event, we're going to connect a Lambda function to this event.

85
00:05:35,290 --> 00:05:37,780
And again we're going to have an action.

86
00:05:37,960 --> 00:05:42,310
And in fact, the only thing I want to do here on the GUI is I want to listen for when an action is

87
00:05:42,310 --> 00:05:47,350
given called we could do something like if action is equal to enable GUI.

88
00:05:47,350 --> 00:05:52,870
So if I go up to a drink machine and enable the proximity prompt, then the server is going to, you

89
00:05:52,870 --> 00:05:58,630
know, verify some stuff and then tell me to enable the GUI on my end, because the server is the one

90
00:05:58,630 --> 00:06:03,400
that's collecting all of the different drink machines and listening to the proximity prompts inside

91
00:06:03,400 --> 00:06:03,970
of them.

92
00:06:04,330 --> 00:06:08,320
So when the specific action gets requested, we can actually have another function.

93
00:06:09,190 --> 00:06:11,170
We can call it open GUI.

94
00:06:11,560 --> 00:06:14,470
And this will be responsible for opening our GUI.

95
00:06:14,470 --> 00:06:18,130
And what we could do here is we could do GUI dot enabled.

96
00:06:18,130 --> 00:06:19,330
Make sure that's set to true.

97
00:06:19,330 --> 00:06:23,620
It should be set to true by default right here.

98
00:06:23,620 --> 00:06:26,230
But just in case it isn't we're going to set it to true.

99
00:06:26,440 --> 00:06:30,430
We're going to do GUI dot frame, set its visibility equal to true.

100
00:06:30,430 --> 00:06:34,300
Because by default the visibility of our frame is set to false.

101
00:06:35,910 --> 00:06:40,770
And then from this point, we could set the original walk speed equal to the local character.

102
00:06:41,450 --> 00:06:45,740
That humanoid dot walk speed.

103
00:06:46,070 --> 00:06:48,740
Same thing with the jump height.

104
00:06:53,580 --> 00:06:57,900
And since the guy is opening on our screen, we want to freeze the player in place.

105
00:06:57,900 --> 00:07:04,260
And the easy way to do that would be to just to access the local player and set the humanoid dot walk

106
00:07:04,260 --> 00:07:08,640
speed property equal to zero, along with the jump height.

107
00:07:13,540 --> 00:07:16,420
And this will stop the player from being able to move around.

108
00:07:17,030 --> 00:07:19,010
So we can call this function right here.

109
00:07:19,010 --> 00:07:22,100
When the server tells us to open a GUI on our screen.

110
00:07:22,100 --> 00:07:26,420
Otherwise, the next thing I'm going to do in this section is I'm going to loop through every single

111
00:07:26,420 --> 00:07:31,580
button that is inside of that buttons table we created.

112
00:07:31,760 --> 00:07:37,550
So for every single thing that exists in that table, which will include all of the children of our

113
00:07:37,550 --> 00:07:38,210
image label.

114
00:07:38,210 --> 00:07:42,620
So all of these things, we want to first verify a few things.

115
00:07:42,620 --> 00:07:46,460
First if the string dot length.

116
00:07:47,350 --> 00:07:49,990
Of this button dot name.

117
00:07:50,380 --> 00:07:53,740
If it's greater than one.

118
00:07:54,430 --> 00:07:59,860
Then we're just going to continue looping, because we only want to care about the specific buttons

119
00:07:59,860 --> 00:08:02,350
that have a name that's only one character long.

120
00:08:02,350 --> 00:08:03,640
We don't want to worry about this.

121
00:08:03,640 --> 00:08:07,660
We don't want to worry about this or any of these other ones.

122
00:08:07,660 --> 00:08:12,610
So if the length of the name of this button is greater than one, then we're just going to continue

123
00:08:12,610 --> 00:08:13,180
looping.

124
00:08:13,750 --> 00:08:18,490
Otherwise, another thing we got to make sure is if this item is a text button.

125
00:08:18,490 --> 00:08:24,070
So if it is not a text button is a text button.

126
00:08:26,080 --> 00:08:27,910
Then we're going to continue looping.

127
00:08:28,600 --> 00:08:33,700
Otherwise, if it's a button and it's one of these ones that have a one character name, then what we

128
00:08:33,700 --> 00:08:35,770
could do is we could do button.

129
00:08:35,770 --> 00:08:40,210
Listen to the event mouse button one up.

130
00:08:41,170 --> 00:08:44,320
And we can connect a lambda function.

131
00:08:44,560 --> 00:08:48,460
And this function is just going to call the on button clicked function.

132
00:08:48,460 --> 00:08:52,450
And in fact we'll pass the button itself to this function.

133
00:08:52,450 --> 00:08:56,140
So in here we can have a parameter for a button.

134
00:08:58,030 --> 00:08:58,630
All right.

135
00:08:58,630 --> 00:09:04,240
The next thing I want to do is I want to listen for each of the buttons that weren't set up by this

136
00:09:04,240 --> 00:09:09,160
for loop, which includes this button, this button, this button and this button.

137
00:09:09,160 --> 00:09:12,130
So we could do GUI dot frame.

138
00:09:12,910 --> 00:09:15,610
Dot image label will wait for.

139
00:09:15,610 --> 00:09:18,760
Let's do the exit button first, just in case it hasn't replicated.

140
00:09:18,760 --> 00:09:23,020
And again we'll listen to mouse button one up.

141
00:09:24,850 --> 00:09:28,090
And we're going to connect a lambda function to this.

142
00:09:29,270 --> 00:09:32,900
First we're going to check if the Debounce is currently active.

143
00:09:32,900 --> 00:09:37,220
So if the Debounce is active then we're just going to return end.

144
00:09:37,370 --> 00:09:42,710
Otherwise, when the player hits the exit button we just want to close our guy.

145
00:09:43,070 --> 00:09:45,710
So that's another thing we could fill out real quick here.

146
00:09:45,710 --> 00:09:47,810
What do we want to do to close the guy?

147
00:09:47,840 --> 00:09:52,610
Well we can set the guy dot frame dot visibility equal to false.

148
00:09:52,610 --> 00:09:56,870
We can set the output box dot text equal to nothing.

149
00:09:56,870 --> 00:10:00,830
That way we can clear any previous message that was in the output box.

150
00:10:01,310 --> 00:10:09,020
And then we could set the local characters dot humanoid, dot walk speed back to the original walk speed

151
00:10:09,020 --> 00:10:12,860
and do the same thing for the jump height.

152
00:10:17,800 --> 00:10:21,640
And we can set Debounce back to false just in case we need to.

153
00:10:21,880 --> 00:10:25,120
We can also go ahead and fill out the on button clicked function as well.

154
00:10:25,120 --> 00:10:28,870
So what do we want to do when one of the buttons on our keyboard gets clicked?

155
00:10:28,870 --> 00:10:35,410
Well, what we could do is of course first check if there is a debounce because we don't want to input

156
00:10:35,410 --> 00:10:40,660
or add anything to our output text label if the Debounce is activated.

157
00:10:40,660 --> 00:10:44,470
However, if it isn't, then we can play that click sound.

158
00:10:46,050 --> 00:10:56,160
And then what we could do is I want to verify that we haven't put too many different, um, characters

159
00:10:56,160 --> 00:11:03,270
into the output text label, so we can actually set a limit to however many text or characters we can

160
00:11:03,270 --> 00:11:06,750
put inside of the output box, because we don't want to put way too many.

161
00:11:06,780 --> 00:11:12,120
We got to we might want to set a limit so we can actually create a constant one.

162
00:11:12,120 --> 00:11:17,700
I'm going to call it Max cars for max characters, and we can set a max character length of something

163
00:11:17,700 --> 00:11:18,930
like 25.

164
00:11:19,200 --> 00:11:25,050
And then I'm also going to actually create a constant for the message when the machine is out of something

165
00:11:25,050 --> 00:11:29,220
or the drink doesn't exist, we can just call it out of range.

166
00:11:29,700 --> 00:11:34,950
Anyways, what we could do inside of our on button click function is we can check.

167
00:11:35,690 --> 00:11:43,190
If stringlength of the output box dot text.

168
00:11:43,580 --> 00:11:52,130
If this is less than max characters, then we can set the output box dot text equal to itself.

169
00:11:54,070 --> 00:12:01,900
And concatenate the string dot upper or get the upper variant of button dot name.

170
00:12:02,260 --> 00:12:07,540
And this is just in case we didn't name one of these particular strings here in upper case.

171
00:12:07,540 --> 00:12:13,480
So if they put n then it'll make sure the output box text isn't greater than 25 characters.

172
00:12:13,480 --> 00:12:16,810
And then it'll concatenate that letter into the output box.

173
00:12:16,810 --> 00:12:17,590
Text.

174
00:12:17,920 --> 00:12:23,800
The next button we could listen to inside of our image label is the space button.

175
00:12:24,830 --> 00:12:31,520
So what we want to happen when we click on our space button.

176
00:12:32,110 --> 00:12:37,360
Well, what we could do is first make sure the debounce is not active.

177
00:12:38,210 --> 00:12:44,180
And now we can basically do the same thing that we did inside of our on button clicked function.

178
00:12:44,570 --> 00:12:50,480
We can make sure that the length of the current output box is text is under 25.

179
00:12:50,480 --> 00:12:56,390
Make sure to play the click sound, and instead of concatenating the name of this button, what we're

180
00:12:56,390 --> 00:13:00,500
going to do is we're just going to concatenate an empty space.

181
00:13:00,500 --> 00:13:03,890
So we'll just have a string with nothing inside of it.

182
00:13:04,560 --> 00:13:08,550
The next one we could do is inside of our frames image label.

183
00:13:08,640 --> 00:13:11,130
We'll wait for the backspace button.

184
00:13:11,790 --> 00:13:15,060
And what do we want to do when this is pressed?

185
00:13:15,990 --> 00:13:21,420
Well what we could do for this one is basically do the exact same things here.

186
00:13:21,420 --> 00:13:27,600
Make sure the debounce isn't active, play the sound, and instead, since we're backspacing or removing

187
00:13:27,600 --> 00:13:34,710
a character from our output box text, we can use the string dot sub function to get a substring of

188
00:13:34,710 --> 00:13:37,170
output box dot text.

189
00:13:38,240 --> 00:13:44,660
And the length is going to be from the first index of our string to the string dot length.

190
00:13:44,990 --> 00:13:50,210
Output box dot text minus one.

191
00:13:50,210 --> 00:13:56,630
So basically we're getting all of the characters from the first index all the way to the second to last

192
00:13:56,630 --> 00:13:57,440
index.

193
00:13:57,920 --> 00:14:03,740
So if we typed in something like hello and we hit backspace, then we'll just get hell.

194
00:14:03,740 --> 00:14:07,790
If we hit backspace again then we'll just get hell and so on.

195
00:14:08,270 --> 00:14:11,990
The next button we need to listen to of course is our enter button.

196
00:14:11,990 --> 00:14:15,890
So frame dot image label wait for enter.

197
00:14:16,810 --> 00:14:18,610
Mouse button one up.

198
00:14:18,610 --> 00:14:20,500
You could use mouse button click as well.

199
00:14:20,500 --> 00:14:22,240
It doesn't really matter that much.

200
00:14:22,240 --> 00:14:25,930
And inside of this one again we want to verify the exact same thing.

201
00:14:25,930 --> 00:14:28,630
Make sure the debounce is not active.

202
00:14:28,630 --> 00:14:34,150
Otherwise, if the Debounce isn't active, this is where we're going to set it to true, because when

203
00:14:34,150 --> 00:14:39,880
the player hits enter, we want to check if this drink they inputted exists, and if it does, we want

204
00:14:39,880 --> 00:14:45,250
to dispense that drink out, and then we'll enable the debounce so we won't be able to manipulate the

205
00:14:45,250 --> 00:14:47,320
output box's text anymore.

206
00:14:47,320 --> 00:14:51,910
So this is where we can create some variables for our, uh, remote function.

207
00:14:51,910 --> 00:14:54,520
So we can have one called success.

208
00:14:54,520 --> 00:14:59,020
And then the remote function we're going to use the check for drink action.

209
00:14:59,020 --> 00:15:06,610
So if we actually go back to our drink class on the server we're going to get returned three different

210
00:15:06,610 --> 00:15:06,910
things.

211
00:15:06,910 --> 00:15:12,730
We're going to get returned, uh, whether or not it was successful, the name or key for the drink,

212
00:15:12,730 --> 00:15:15,250
and then all of the information for the drink.

213
00:15:15,250 --> 00:15:17,290
So we can have one called success.

214
00:15:17,290 --> 00:15:19,270
We can have one called drink name.

215
00:15:19,270 --> 00:15:21,880
And then the properties for this particular drink.

216
00:15:21,880 --> 00:15:27,310
And we're going to use the request drink function and invoke to the server.

217
00:15:27,310 --> 00:15:29,290
We want to check for a drink.

218
00:15:29,290 --> 00:15:31,330
And what drink do we want to check for.

219
00:15:31,330 --> 00:15:35,860
Well we want to check for the one that was inputted inside of our output box.

220
00:15:36,340 --> 00:15:44,260
And the way to do that would be to use string dot lower, because the output box's text is going to

221
00:15:44,260 --> 00:15:45,340
be all in uppercase.

222
00:15:45,340 --> 00:15:47,290
So we want to make sure it's lowercase.

223
00:15:47,710 --> 00:15:51,220
And then we could do output box dot text.

224
00:15:51,220 --> 00:15:56,860
So if we typed in something like uh juice then it'll make it all lowercase.

225
00:15:56,860 --> 00:15:59,470
And then it's going to request for the server to check.

226
00:15:59,470 --> 00:16:03,910
And it's going to look to see if a particular drink has this string.

227
00:16:03,910 --> 00:16:08,050
So for every possible name it's going to check if it has something like that.

228
00:16:08,050 --> 00:16:10,780
Then it's going to return that particular drink to us.

229
00:16:11,490 --> 00:16:15,120
And then we can just easily check if success.

230
00:16:15,120 --> 00:16:19,620
Then we can call the dispense drink function and dispense the drink out.

231
00:16:20,390 --> 00:16:26,930
Otherwise, what we could do is we could set the output box dot text equal to the output message or

232
00:16:26,930 --> 00:16:32,030
out of range, and then we could make the out of range message blink a couple of times if we like.

233
00:16:32,030 --> 00:16:34,910
So we could have a for loop that just loops three times.

234
00:16:38,270 --> 00:16:43,070
Then we could wait for some arbitrary amount of time, like 0.5 seconds.

235
00:16:43,830 --> 00:16:49,050
And then we can do output box dot text transparency.

236
00:16:50,040 --> 00:16:52,590
We can set it to one to make it invisible.

237
00:16:52,590 --> 00:16:58,170
And then we can wait again for another 0.5 seconds and then set it to be visible again.

238
00:17:00,090 --> 00:17:05,940
And once that for loop is finished, we can just set output box dot text back to be nothing again and

239
00:17:05,940 --> 00:17:08,580
we'll set Debounce back to false.

240
00:17:09,200 --> 00:17:14,570
So some events we want to listen to for the player is when a child gets added to the backpack.

241
00:17:14,570 --> 00:17:21,560
So child added we want to connect our on child added to backpack function and make a reference to it.

242
00:17:21,920 --> 00:17:26,600
We also want to listen for when a child gets added to the player itself.

243
00:17:29,340 --> 00:17:34,980
And the thing we want to listen to that gets added to our player is actually the backpack folder.

244
00:17:35,220 --> 00:17:42,690
And this is because since our GUI has the reset on spawn property disabled, this guy is going to be

245
00:17:42,690 --> 00:17:43,650
here forever.

246
00:17:43,650 --> 00:17:47,730
So that means let's say the player dies and their character respawns.

247
00:17:47,730 --> 00:17:53,130
Well, when that happens, their backpack folder actually gets deleted and a new one gets set in its

248
00:17:53,130 --> 00:17:53,790
place.

249
00:17:53,790 --> 00:18:00,690
So that means when that happens, we got to reattach the on child added to backpack event to this new

250
00:18:00,690 --> 00:18:01,800
backpack item.

251
00:18:01,800 --> 00:18:06,090
So that's why we got to listen for when a new child gets added to our player object, which would be

252
00:18:06,090 --> 00:18:07,470
the backpack folder.

253
00:18:07,470 --> 00:18:12,360
So we could make sure that whatever child is being added to our player is the backpack folder.

254
00:18:12,360 --> 00:18:18,870
So if child dot name is not equal to backpack, then we're just going to return because we don't care

255
00:18:18,870 --> 00:18:19,290
about it.

256
00:18:19,290 --> 00:18:25,860
However, if it is the backpack, then we can do the exact same thing here and we'll just replace this

257
00:18:25,860 --> 00:18:27,240
with child.

258
00:18:27,900 --> 00:18:32,250
And then one last thing I want to make sure to do is I want to listen for when a character gets added

259
00:18:32,250 --> 00:18:33,300
to my player.

260
00:18:34,670 --> 00:18:37,190
Get that character in our lambda function.

261
00:18:38,080 --> 00:18:43,000
And then I want to make sure to update our local character property equal to this new character, because

262
00:18:43,000 --> 00:18:48,400
again, the script is going to exist forever because our gene does not get reset when a player dies.

263
00:18:48,400 --> 00:18:52,690
And we want to constantly update the character variable just in case the player dies.

264
00:18:52,720 --> 00:18:55,420
Now we can go ahead and fill out these two functions.

265
00:18:55,420 --> 00:19:00,370
So the first one we could do is on child added to backpack, which should be relatively straightforward.

266
00:19:00,370 --> 00:19:06,730
What we're going to do is we want to make sure that whatever child is being added to the backpack is

267
00:19:06,730 --> 00:19:07,540
a tool.

268
00:19:07,540 --> 00:19:14,800
So if not child is a tool, then we're just going to return.

269
00:19:15,720 --> 00:19:22,230
Uh, another thing we want to check is if this tool has the git attribute, the drink id.

270
00:19:22,230 --> 00:19:28,440
So if this tool does not have this ID so if not ID then we're going to return as well because we don't

271
00:19:28,440 --> 00:19:29,580
care about this tool.

272
00:19:29,580 --> 00:19:33,090
Otherwise if it does have the ID then it is a drink object.

273
00:19:33,090 --> 00:19:38,010
And we want to create a new drink object on the client in case we haven't already.

274
00:19:38,010 --> 00:19:40,590
So that's where the drink class comes into play.

275
00:19:40,590 --> 00:19:44,340
We can call the constructor, we can pass the guy.

276
00:19:44,790 --> 00:19:50,820
And if you remember, the second one we have to pass would be the particular key for this drink.

277
00:19:50,820 --> 00:19:55,500
But since we're going to be using the ID for this drink, I don't really care about this drink name

278
00:19:55,500 --> 00:19:55,980
property.

279
00:19:55,980 --> 00:19:58,350
So I can just pass an empty string.

280
00:19:58,350 --> 00:20:04,950
Or in this case I'll just do child dot uh, name because I really want to pass the ID that is stored

281
00:20:04,950 --> 00:20:09,540
for this object, because when we call this constructor, it's going to check whether or not it has

282
00:20:09,540 --> 00:20:15,780
an ID, and if it does, then it's going to get an object from the server that has this particular ID.

283
00:20:16,500 --> 00:20:18,630
And then inside of the dispense drink function.

284
00:20:18,630 --> 00:20:23,940
What I actually want to do is I want to have the key or the drink name for this particular drink passed

285
00:20:23,940 --> 00:20:27,000
to the function, as well as the properties for the function.

286
00:20:27,000 --> 00:20:33,240
So when we actually call this function down here, I want to be able to pass the drink name and the

287
00:20:33,240 --> 00:20:34,800
properties for the drink.

288
00:20:34,800 --> 00:20:40,080
And then from this point, using those properties, what I'm going to do is I'm going to set the output

289
00:20:40,080 --> 00:20:44,370
box dot text equal to the properties.

290
00:20:44,370 --> 00:20:47,160
And we're going to get the dispense message.

291
00:20:47,160 --> 00:20:50,310
So dot dispense message.

292
00:20:51,200 --> 00:20:55,160
So that's going to be whatever the dispensed message is for that particular drink.

293
00:20:55,160 --> 00:21:00,440
So if I go into pre-made drinks, if I got a cup of air, the dispense message would just be the default

294
00:21:00,440 --> 00:21:01,640
of dispensing.

295
00:21:02,120 --> 00:21:08,780
And then from this point I could do properties dot get the dispense sound and play that.

296
00:21:09,020 --> 00:21:12,200
And then I'm going to wait for that dispense sound to end.

297
00:21:12,200 --> 00:21:15,140
So dispense sound dot ended.

298
00:21:15,140 --> 00:21:17,000
We'll wait for that event to fire.

299
00:21:17,000 --> 00:21:24,710
And when it does then we can use the comms event and we can fire to the server to create a drink object.

300
00:21:25,200 --> 00:21:29,880
And the drink object we want to create is going to be this particular key.

301
00:21:30,060 --> 00:21:34,800
So the server will go create that drink object and add it to our backpack.

302
00:21:34,800 --> 00:21:40,290
And when it gets added to our backpack then that's when this event down here gets fired and calls the

303
00:21:40,290 --> 00:21:42,300
on child added to backpack.

304
00:21:42,750 --> 00:21:47,490
And then from that point, once we've dispensed our drink, then we can close out the GUI.

305
00:21:47,490 --> 00:21:52,860
So we dispense our drink and then once it gets dispensed and placed in our inventory, we can close

306
00:21:52,860 --> 00:21:54,420
the GUI on our end.

307
00:21:55,300 --> 00:21:55,720
All right.

308
00:21:55,720 --> 00:21:57,250
Seems pretty good so far.

309
00:21:57,250 --> 00:22:02,380
And in fact, since we're using this constant out of range here inside of our local script, I don't

310
00:22:02,380 --> 00:22:05,290
think we actually need it to exist within.

311
00:22:05,290 --> 00:22:05,890
Where was it?

312
00:22:05,890 --> 00:22:08,500
Yeah, inside of our pre-made drinks module script.

313
00:22:08,500 --> 00:22:12,250
We don't need it in here, so I'll just delete that.

314
00:22:12,550 --> 00:22:14,200
And otherwise we're almost finished.

315
00:22:14,200 --> 00:22:18,760
The last thing we need to do is set up our server script and make some drinks.

316
00:22:18,760 --> 00:22:20,740
So I'll see you in the next lecture.
