00:00:00,200 --> 00:00:01,610
Welcome back.

2
00:00:01,610 --> 00:00:02,960
I hope your quiz went well.

3
00:00:02,960 --> 00:00:09,380
And now we're going to practice a little bit using RBC's script signals or AKA events.

4
00:00:09,380 --> 00:00:14,870
For this practice activity, we're going to be using an instance called a proximity prompt.

5
00:00:14,870 --> 00:00:20,510
We'll dive more into this instance in a future lecture, but for now we want to utilize an event in

6
00:00:20,510 --> 00:00:22,880
the instance called trigger.

7
00:00:22,880 --> 00:00:27,860
And this will get fired when a player interacts and triggers the prompt.

8
00:00:27,860 --> 00:00:32,570
So it says the event is triggered when the prompt key slash button is pressed, or after a specified

9
00:00:32,570 --> 00:00:36,290
amount of time holding the button if the whole duration is used.

10
00:00:36,290 --> 00:00:41,870
So for this practice activity, I would like for you to have a script that listens to a proximity prompts

11
00:00:41,870 --> 00:00:45,740
triggered event and then do something in the game, whatever you'd like.

12
00:00:45,740 --> 00:00:51,320
I'm going to have my prompt change a parts color to something random, but feel free to do something

13
00:00:51,320 --> 00:00:52,430
else if you'd like.

14
00:00:52,430 --> 00:01:01,080
So back in studio, let's create a brand new part, and then let's go ahead and add a proximity prompt

15
00:01:01,080 --> 00:01:03,300
instance inside of the part.

16
00:01:03,600 --> 00:01:07,320
And now we're going to need a script to listen to this prompts event.

17
00:01:07,320 --> 00:01:12,990
So take a few minutes, do the practice activity and then I will show you my solution next.

18
00:01:13,050 --> 00:01:13,710
All right.

19
00:01:13,710 --> 00:01:20,130
To make this quick and easy, let's just go ahead and add a new script inside of our part and inside

20
00:01:20,130 --> 00:01:20,940
of our script.

21
00:01:20,940 --> 00:01:26,040
Let's go ahead and make a reference to the part so we can have a variable called part that's equal to

22
00:01:26,040 --> 00:01:27,240
script dot parent.

23
00:01:27,240 --> 00:01:30,330
And then we can also have a reference to our proximity prompt.

24
00:01:30,330 --> 00:01:32,160
So I'll just call this variable prompt.

25
00:01:32,160 --> 00:01:35,820
And that's going to be equal to our part dot proximity prompt.

26
00:01:36,090 --> 00:01:40,290
And then like I said there is an event inside of this prompt called triggered.

27
00:01:40,290 --> 00:01:47,370
And we want to go ahead and use the connect function to connect a function to listen to this event.

28
00:01:47,370 --> 00:01:52,800
And this function, if we take a look, is going to be passed the player who triggered the proximity

29
00:01:52,800 --> 00:01:53,310
prompt.

30
00:01:53,310 --> 00:01:56,250
If you want to mess around and see what you can do with the player, go ahead.

31
00:01:56,250 --> 00:02:02,280
But what I'm going to do here is I'm going to set the parts color to a random color every single time

32
00:02:02,280 --> 00:02:03,540
the prompt is triggered.

33
00:02:03,540 --> 00:02:07,920
So let me create a variable for storing a random number generator.

34
00:02:07,920 --> 00:02:09,840
We'll do random dot new.

35
00:02:10,710 --> 00:02:17,300
And then when the prompt is triggered, we can simply do part dot color is going to be equal to a new

36
00:02:17,300 --> 00:02:18,020
color three.

37
00:02:18,020 --> 00:02:20,540
So we'll do color three dot new.

38
00:02:20,540 --> 00:02:26,750
And then we can use our random number generator and call the next number function to generate a random

39
00:02:26,750 --> 00:02:28,580
number between 0 and 1.

40
00:02:28,820 --> 00:02:30,380
And we'll just do that three.

41
00:02:30,380 --> 00:02:34,040
Time for the red, green and blue color property.

42
00:02:34,040 --> 00:02:35,330
And we should be good to go.

43
00:02:35,330 --> 00:02:43,730
So if I go and play test my game and here's my character, if I interact with the prompts, look at

44
00:02:43,730 --> 00:02:44,540
that part.

45
00:02:44,540 --> 00:02:45,470
Color changes.

46
00:02:45,470 --> 00:02:48,080
So we got a red or we got kind of an orange.

47
00:02:48,080 --> 00:02:48,680
We got a purple.

48
00:02:48,680 --> 00:02:49,940
Now green.

49
00:02:49,940 --> 00:02:50,870
Pretty cool.

50
00:02:50,870 --> 00:02:55,520
And it is firing that event every single time I'm interacting with this prompt.

51
00:02:55,520 --> 00:02:58,820
Let's have a little bit more fun with this event.

52
00:02:58,820 --> 00:03:05,380
When we change the color, let's go ahead and clone our part and basically have it duplicate itself.

53
00:03:05,380 --> 00:03:10,030
So we have another color changing part, and every single time the prompt is activated, we'll just

54
00:03:10,030 --> 00:03:11,770
create more and more parts.

55
00:03:11,770 --> 00:03:17,410
So the easiest way we could do that is we could just simply refer to our part and make a clone of it.

56
00:03:17,410 --> 00:03:19,060
So we'll make a variable called clone.

57
00:03:19,060 --> 00:03:21,790
And that's going to be equal to part clone.

58
00:03:21,790 --> 00:03:27,700
And then let's go ahead and change this clones position to be equal to the part's position.

59
00:03:27,700 --> 00:03:30,730
But we're going to offset it on the y axis.

60
00:03:30,760 --> 00:03:34,780
Let's just do an offset on the y axis of like uh, I don't know.

61
00:03:34,780 --> 00:03:36,130
Let's do four studs.

62
00:03:36,670 --> 00:03:42,400
And then once we set the position, we need to set this new clone's parent into the workspace.

63
00:03:42,400 --> 00:03:46,510
Because when we clone the part right now, its parent is going to be set to nil.

64
00:03:46,510 --> 00:03:48,070
You won't be able to see it anywhere.

65
00:03:48,070 --> 00:03:52,030
And then once we set its parent to the workspace, we'll be able to see it in the game.

66
00:03:52,030 --> 00:03:56,440
So now if I go and interact with my part, as you can see, we've just created another new part.

67
00:03:56,440 --> 00:03:59,080
And then if I interact with that one, it's going to create another new part.

68
00:03:59,080 --> 00:04:02,440
And if I interact with the one on top, it'll create another new part.

69
00:04:02,440 --> 00:04:03,310
Pretty cool.

70
00:04:03,310 --> 00:04:08,110
Let's actually go ahead and make these parts unanchored.

71
00:04:08,110 --> 00:04:12,820
So I'll just select each of these and disable the anchored property on the server side.

72
00:04:12,820 --> 00:04:16,450
And then let's go back to the client and let's just start spamming these buttons.

73
00:04:16,450 --> 00:04:21,760
So now if I do that I am creating a whole bunch of different parts.

74
00:04:23,830 --> 00:04:25,780
And they just keep duplicating themselves.

75
00:04:25,780 --> 00:04:30,340
And I'm able to keep continually cloning more and more parts.

76
00:04:30,340 --> 00:04:34,150
And then of course, if you have more players in the game, all your other players could be interacting

77
00:04:34,150 --> 00:04:36,070
with these parts as well and just creating more of them.

78
00:04:36,070 --> 00:04:37,330
So this looks kind of funny.

79
00:04:37,960 --> 00:04:40,690
And like I said, you could really do whatever you want.

80
00:04:40,690 --> 00:04:45,910
So instead of maybe cloning the part, maybe we want to play like a fart sound because we're goofy like

81
00:04:45,910 --> 00:04:46,270
that.

82
00:04:46,270 --> 00:04:52,570
So let's go to the toolbox and let's search through the audio and let's just search for a fart.

83
00:04:52,570 --> 00:04:53,410
And let's see.

84
00:04:53,410 --> 00:04:53,800
Here we go.

85
00:04:53,800 --> 00:04:55,150
Let's see what this one sounds like.

86
00:04:56,410 --> 00:04:57,370
Perfect.

87
00:04:57,370 --> 00:05:01,150
So let's go ahead and insert this sound into our part.

88
00:05:01,150 --> 00:05:05,260
And then just to make sure it doesn't play for like everyone, I'm just going to set the rolloff max

89
00:05:05,260 --> 00:05:07,540
distance to like 50 studs.

90
00:05:08,470 --> 00:05:13,210
And then what we can go ahead and do is we can refer to this sound in our script.

91
00:05:13,210 --> 00:05:15,580
We'll make a variable called sound.

92
00:05:15,910 --> 00:05:18,610
And that's going to be equal to part dot.

93
00:05:18,610 --> 00:05:20,530
And the name is fart meme.

94
00:05:20,530 --> 00:05:21,370
There we go.

95
00:05:21,370 --> 00:05:26,560
And then when the prompt is triggered we can refer to our sound and simply call the play function on

96
00:05:26,560 --> 00:05:28,120
it to play it in the game.

97
00:05:28,120 --> 00:05:30,370
So now every time I interact with my part.

98
00:05:33,250 --> 00:05:33,820
There you go.

99
00:05:33,820 --> 00:05:35,260
We play a fart sound now.

100
00:05:35,950 --> 00:05:39,340
So I encourage you to continue messing around with this event.

101
00:05:39,340 --> 00:05:40,420
See what else you can make.

102
00:05:40,420 --> 00:05:40,840
Mess around.

103
00:05:40,840 --> 00:05:43,720
Maybe with the player, the player's character spawn parts.

104
00:05:43,720 --> 00:05:44,680
Do whatever you'd like.

105
00:05:44,710 --> 00:05:47,980
The most important thing is that you're practicing and you're experimenting.

106
00:05:47,980 --> 00:05:53,440
And if you ever encounter any mistakes or you encounter an error, that is a great opportunity to practice

107
00:05:53,440 --> 00:05:55,060
debugging as well.

108
00:05:55,090 --> 00:05:58,120
Hope you enjoyed this lecture and I will see you in the next one.
