1
00:00:00,560 --> 00:00:07,220
All right, So I'm in my zombie game and we have our boulder traps set up just the parts, no scripts.

2
00:00:07,220 --> 00:00:10,160
We've got to ramp our stop or our boulder and a trigger.

3
00:00:10,160 --> 00:00:12,280
So we need to make this work.

4
00:00:12,290 --> 00:00:18,740
Let's go over to our boulder trap and start doing some scripting on the boulder trap level.

5
00:00:18,740 --> 00:00:20,300
I'm going to add a script here.

6
00:00:20,300 --> 00:00:22,940
I'll hit the plus sign script.

7
00:00:22,940 --> 00:00:27,890
And the reason I have it on this level is this script is going to interact with more than one part.

8
00:00:27,890 --> 00:00:31,280
If it was only going to interact with one part, I'd put it on that part.

9
00:00:31,280 --> 00:00:37,310
But we are going to have to interact with both the stopper and the trigger and actually we're going

10
00:00:37,310 --> 00:00:40,940
to do the boulder in the next video because we want to put sound on it.

11
00:00:40,940 --> 00:00:44,180
So I'm going to call this script trigger it.

12
00:00:44,180 --> 00:00:44,600
Right.

13
00:00:44,600 --> 00:00:46,280
Hopefully that's not too close to a name.

14
00:00:46,280 --> 00:00:47,290
Is Trigger, right?

15
00:00:47,330 --> 00:00:48,740
Trigger It is the script.

16
00:00:48,740 --> 00:00:51,440
And you got a little icon that makes it look like a script, too.

17
00:00:51,680 --> 00:00:54,650
So let's get a variable for our boulder trap.

18
00:00:55,060 --> 00:00:58,940
Let's say a boulder trap, and that's script dot parent.

19
00:00:59,210 --> 00:01:02,060
And then in the boulder trap, we have a trigger.

20
00:01:02,060 --> 00:01:08,990
We're going to need a variable for that trigger boulder trap trigger, right?

21
00:01:08,990 --> 00:01:14,950
So Boulder trap is on the model level, and the trigger is one child underneath, right?

22
00:01:14,960 --> 00:01:17,420
The first child of the boulder trap.

23
00:01:18,140 --> 00:01:18,740
Cool.

24
00:01:18,740 --> 00:01:20,420
And then we'll get the stopper.

25
00:01:20,420 --> 00:01:21,810
Stopper is the same thing, right?

26
00:01:21,830 --> 00:01:24,680
We have Boulder trap dot and you can even see it there.

27
00:01:24,680 --> 00:01:25,550
Stopper.

28
00:01:25,820 --> 00:01:26,210
Cool.

29
00:01:26,210 --> 00:01:28,010
If you don't see it, then you're going to have to look around.

30
00:01:28,010 --> 00:01:28,670
Something happen.

31
00:01:28,670 --> 00:01:29,600
Something went wrong.

32
00:01:30,020 --> 00:01:35,390
All right, Now we need a function to handle our touch event for the trigger.

33
00:01:35,390 --> 00:01:40,940
So when I say local function, we're only going to have one touch event in this in this script.

34
00:01:40,940 --> 00:01:42,890
So I'm going to call this on touch.

35
00:01:43,790 --> 00:01:45,230
What's that other part?

36
00:01:45,230 --> 00:01:45,620
Right.

37
00:01:45,620 --> 00:01:47,780
Whenever we do a touch event, we're going to get another part.

38
00:01:47,780 --> 00:01:49,460
That's the part that touched our part.

39
00:01:49,790 --> 00:01:52,520
And the part that we're touching is the trigger.

40
00:01:52,790 --> 00:01:57,920
So we have the trigger touched, connect on touch.

41
00:01:57,920 --> 00:02:01,220
So this will be like a foot or something like that?

42
00:02:01,220 --> 00:02:02,150
Probably a foot.

43
00:02:02,150 --> 00:02:03,170
We're going to step on it.

44
00:02:03,470 --> 00:02:05,210
So if it is a foot.

45
00:02:05,840 --> 00:02:12,650
The parent will be the character, and then we'll be able to find a humanoid proving that it is a character

46
00:02:12,650 --> 00:02:14,250
or a non playing character.

47
00:02:14,270 --> 00:02:17,090
If a ball rolls over it, we're not going to trigger the trap.

48
00:02:17,300 --> 00:02:20,510
So I'm going to look for the humanoid local cube.

49
00:02:20,540 --> 00:02:21,380
That's my variable.

50
00:02:21,600 --> 00:02:32,690
Some other part, maybe a foot parent find first child that is a humanoid.

51
00:02:33,080 --> 00:02:39,380
So if this is the character, there will be a humanoid, if it's the character and then let's do it

52
00:02:39,380 --> 00:02:44,930
if statement just to make sure, make sure it wasn't something weird that happened like a ball or I

53
00:02:44,930 --> 00:02:46,520
don't know, something else, a tree.

54
00:02:47,210 --> 00:02:48,380
Let's go ahead.

55
00:02:48,380 --> 00:02:53,780
And now that we know that it's the humanoid, we are going to remove the stopper.

56
00:02:54,650 --> 00:02:55,970
How do we remove the stopper?

57
00:02:55,970 --> 00:03:00,680
I'm always going to put hinges on it, but I'm just going to make it easy because this is our first

58
00:03:01,160 --> 00:03:02,880
kind of our first game asset, right?

59
00:03:02,930 --> 00:03:09,770
We did some simple ones with the coin and the health but let's do stopper will make can collide equal

60
00:03:09,770 --> 00:03:15,950
to false so it's essentially not holding back the ball, the the ball or the boulder and then we'll

61
00:03:15,950 --> 00:03:20,870
get the stopper transparency and make it invisible.

62
00:03:20,870 --> 00:03:23,360
One essentially, boom, it's gone.

63
00:03:23,720 --> 00:03:25,730
Let's go ahead and try it out, see what we got.

64
00:03:29,410 --> 00:03:31,120
You should put a print statement in there, too.

65
00:03:31,150 --> 00:03:34,000
That's a good way to check to see what's happening.

66
00:03:34,270 --> 00:03:36,350
We can go here to view output window.

67
00:03:36,370 --> 00:03:38,140
We don't have any print statements in there.

68
00:03:38,170 --> 00:03:39,090
I know this will work.

69
00:03:39,100 --> 00:03:39,880
It's pretty simple.

70
00:03:39,880 --> 00:03:40,930
But if it doesn't.

71
00:03:42,910 --> 00:03:44,920
So there's no damaged script, so it doesn't hurt you.

72
00:03:44,920 --> 00:03:47,560
But we're going to do that, too, if you.

73
00:03:47,560 --> 00:03:48,640
If it doesn't work for you.

74
00:03:48,640 --> 00:03:55,570
If the boulder doesn't go, what you should do is put print statements above the if statement and below

75
00:03:55,570 --> 00:04:00,160
the statement down in here to see what's being printed out.

76
00:04:00,190 --> 00:04:08,440
Typically this is spelt wrong or you forgot that or you'll see something red down here, red and scary,

77
00:04:08,440 --> 00:04:09,910
and then you'll know that something went wrong.

78
00:04:09,910 --> 00:04:11,860
So that's how you do some troubleshooting.

79
00:04:12,100 --> 00:04:12,550
All right.

80
00:04:12,550 --> 00:04:17,110
So the next video we're going to add to this, we're going to have to make the ball go back.

81
00:04:17,120 --> 00:04:18,520
We're going to have to put damage on there.

82
00:04:18,520 --> 00:04:20,350
We're going to put a sound on there.
