1
00:00:00,810 --> 00:00:01,500
Hey there.

2
00:00:01,500 --> 00:00:02,190
Welcome.

3
00:00:02,190 --> 00:00:07,560
In this lecture, we'll be scripting our final trap, which is a shotgun hidden in a tree.

4
00:00:07,560 --> 00:00:12,060
When our player steps on a pressure plate, it's going to trigger the shotgun and kill our player.

5
00:00:12,060 --> 00:00:15,630
So if I go walk over here and trigger a pressure plate, there you go.

6
00:00:15,630 --> 00:00:17,610
The shotgun shoots and kills me.

7
00:00:18,000 --> 00:00:20,160
So let's go ahead and get started.

8
00:00:21,310 --> 00:00:22,780
Same procedure as before.

9
00:00:22,780 --> 00:00:27,640
I'll create a new module script in the handler section for my starter player scripts, and I'm going

10
00:00:27,640 --> 00:00:30,400
to call this my shotgun trap handler.

11
00:00:31,320 --> 00:00:32,160
Inside of here.

12
00:00:32,160 --> 00:00:38,520
We'll paste in that same template as before, and I'll rename this to Shotgun Trap Handler.

13
00:00:38,550 --> 00:00:40,380
We'll get rid of the start function.

14
00:00:40,380 --> 00:00:42,480
We'll grab the collection service.

15
00:00:46,190 --> 00:00:50,840
And then we'll go ahead and define the tag for this module.

16
00:00:50,840 --> 00:00:55,340
And the tag for our shotgun trap is just shotgun trap.

17
00:00:56,950 --> 00:01:00,610
And then we can go ahead and create the other module script to act as our class.

18
00:01:00,610 --> 00:01:04,660
I'm going to call this the Shotgun trap class.

19
00:01:05,350 --> 00:01:07,300
We'll paste in that class template.

20
00:01:07,300 --> 00:01:11,740
We'll rename it to Shotgun Trap Class.

21
00:01:11,740 --> 00:01:15,160
And then we can go ahead and require that class within our handler.

22
00:01:15,160 --> 00:01:21,190
So shotgun trap class is equal to require script dot shotgun trap class.

23
00:01:22,030 --> 00:01:25,630
And then we'll listen to the collection service get instance added signal.

24
00:01:25,630 --> 00:01:33,490
Pass our tag, connect a function, get the instance, and then use our shotgun trap class dot new constructor.

25
00:01:33,490 --> 00:01:35,440
On this instance, boom!

26
00:01:35,440 --> 00:01:36,880
We already know what to do.

27
00:01:37,870 --> 00:01:42,160
Then in here I'll rename this to our Shotgun Trap objects.

28
00:01:43,800 --> 00:01:45,960
And then we can go ahead and grab some services.

29
00:01:45,960 --> 00:01:49,770
One is going to be the sound service to grab that shotgun sound.

30
00:01:49,770 --> 00:01:52,350
We'll need the player service.

31
00:01:53,810 --> 00:01:58,910
And they're also going to get the tween service to tween that pressure plate up and down when a player

32
00:01:58,910 --> 00:01:59,600
touches it.

33
00:02:01,760 --> 00:02:04,220
Then we can go ahead and make a couple references.

34
00:02:04,220 --> 00:02:06,380
One is going to be for the local player.

35
00:02:06,380 --> 00:02:13,610
So players local player will make a reference to the shotgun shoot sound and that's in sound service

36
00:02:13,850 --> 00:02:16,160
SFX shotgun shoot.

37
00:02:17,530 --> 00:02:20,110
And then we'll also get the pressure plate sound.

38
00:02:20,110 --> 00:02:25,690
So pressure plate sound that's in sound service SFX dot pressure plate.

39
00:02:26,760 --> 00:02:31,740
Then inside of our constructor, we could go ahead and make a reference to our model SCL two model.

40
00:02:31,740 --> 00:02:38,400
We'll get the pressure plate and inside of our model that part is just called pressure plate.

41
00:02:39,100 --> 00:02:43,270
We'll also go ahead and get the, um.

42
00:02:44,370 --> 00:02:45,060
Emitter.

43
00:02:45,060 --> 00:02:48,360
There's a particle emitter for emitting a flash.

44
00:02:48,360 --> 00:02:50,070
So that's going to be our muzzle flash.

45
00:02:50,070 --> 00:02:54,210
So I'll call this muzzle flash emitter.

46
00:02:54,210 --> 00:02:56,280
And that's located inside of our model.

47
00:02:56,280 --> 00:02:57,840
We'll get the shotgun.

48
00:02:57,840 --> 00:03:02,580
And inside of the shotgun there's an attachment named Attachment Muzzle.

49
00:03:02,580 --> 00:03:06,480
And inside of that muzzle we have a muzzle flash emitter.

50
00:03:07,460 --> 00:03:10,820
And then we also have a light instance in there to like flicker.

51
00:03:10,820 --> 00:03:14,120
So it looks like the shotgun shot and lit up the area around it.

52
00:03:14,120 --> 00:03:15,350
So we'll just call this light.

53
00:03:15,350 --> 00:03:17,810
And that's equal to model dot shotgun.

54
00:03:18,170 --> 00:03:23,510
And inside of the attachment muzzle we also have a point light instance.

55
00:03:24,200 --> 00:03:28,820
And last but not least we can have a Debounce called on cooldown and set that equal to false.

56
00:03:29,300 --> 00:03:32,780
Then inside of our model we have another part called Detect Zone.

57
00:03:32,780 --> 00:03:38,780
We'll listen for when that gets touched, connect a function and get the other part that touched it.

58
00:03:40,390 --> 00:03:43,360
And then again, we'll see if a player touched that part.

59
00:03:43,360 --> 00:03:47,860
So players get player from character, pass other part parent.

60
00:03:48,340 --> 00:03:51,280
And if we do not have a player then we'll just return.

61
00:03:53,170 --> 00:03:59,140
Otherwise, we can go ahead and define a function for when the shotgun is triggered or the pressure

62
00:03:59,140 --> 00:04:00,010
plate is triggered.

63
00:04:00,490 --> 00:04:03,850
I'll create a function and I'll just call this triggered.

64
00:04:05,290 --> 00:04:09,670
And we'll call this function from this lambda function.

65
00:04:10,530 --> 00:04:11,820
Inside of our triggered function.

66
00:04:11,820 --> 00:04:15,180
What we can go ahead and do is check if we're on cooldown.

67
00:04:15,330 --> 00:04:18,240
If we are, then we'll return.

68
00:04:18,270 --> 00:04:24,930
Otherwise, set on cooldown equal to true and then we can go ahead and clone our pressure plate sound.

69
00:04:24,930 --> 00:04:26,310
So I'll just call it pressure sound.

70
00:04:26,310 --> 00:04:29,400
And that's equal to pressure plate sound clone.

71
00:04:29,550 --> 00:04:33,480
And we'll set play on remove equal to true.

72
00:04:33,840 --> 00:04:39,600
The parent is going to be equal to self dot model dot pressure plate.

73
00:04:40,630 --> 00:04:43,900
And then we'll just destroy the sound to play the pressure plate sound.

74
00:04:44,530 --> 00:04:48,490
And then afterwards, we want to go ahead and tween the pressure plate to move downwards to look like

75
00:04:48,490 --> 00:04:49,150
we stepped on it.

76
00:04:49,150 --> 00:04:54,820
So tween service will create a new tween on self dot model dot pressure plate.

77
00:04:54,820 --> 00:04:56,770
We'll do a tween info dot new.

78
00:04:56,800 --> 00:04:58,240
We'll play for like 0.5 seconds.

79
00:04:58,240 --> 00:05:00,280
It doesn't really matter how long you want to do it.

80
00:05:00,550 --> 00:05:08,650
And we're going to update the position of the pressure plate equal to self dot model, dot pressure

81
00:05:08,650 --> 00:05:10,510
plate dot position.

82
00:05:10,510 --> 00:05:13,360
And then we're going to offset it with a new vector three.

83
00:05:13,360 --> 00:05:18,520
And we're going to move it um minus one in the y direction.

84
00:05:19,810 --> 00:05:22,090
And then we can just play this tween.

85
00:05:22,090 --> 00:05:28,090
And then afterwards we can wait for the duration of this tween which is 0.5 seconds.

86
00:05:28,090 --> 00:05:34,000
Or we can also just store the tween in a variable and listen to when the event completes instead.

87
00:05:34,390 --> 00:05:35,410
Either way works.

88
00:05:35,410 --> 00:05:37,390
So we'll do it this way.

89
00:05:37,390 --> 00:05:41,560
So when tween dot completed fires, we're going to wait for that event.

90
00:05:43,090 --> 00:05:46,570
And then once that event fires, we're going to clone the shoot sound.

91
00:05:46,570 --> 00:05:48,610
So we'll call this shoot sound.

92
00:05:48,610 --> 00:05:52,120
And that's equal to shotgun shoot sound.

93
00:05:52,120 --> 00:05:54,580
Clone that shoot sound.

94
00:05:54,580 --> 00:05:57,700
We're going to set play on remove also equal to true.

95
00:05:58,390 --> 00:06:03,490
The parent is going to be equal to uh self dot model dot shotgun.

96
00:06:03,490 --> 00:06:05,890
And then we can just set it uh to the attachment.

97
00:06:05,890 --> 00:06:10,990
So attachment muzzle and then we'll destroy the sound instance.

98
00:06:11,710 --> 00:06:16,900
And then once we do that, we can go ahead and emit that muzzle flash from the particle emitter.

99
00:06:16,900 --> 00:06:22,060
So self dot muzzle flash emitter, we're going to emit one particle.

100
00:06:22,450 --> 00:06:26,020
And then we're also going to enable the light in our shotgun.

101
00:06:26,950 --> 00:06:32,170
And since we want this light to flicker on and then back off we can delay a function.

102
00:06:32,960 --> 00:06:38,570
For a very short duration, and that duration is going to be how long our muzzle flash exists for,

103
00:06:38,570 --> 00:06:41,720
so we can refer to our muzzle flash emitter.

104
00:06:42,900 --> 00:06:47,910
And then we can refer to the lifetime property, which is a number sequence, and then get the max value

105
00:06:47,910 --> 00:06:48,510
in there.

106
00:06:49,220 --> 00:06:55,550
And then once that time is up, we can go ahead and set self dot light dot enabled back equal to false.

107
00:06:56,420 --> 00:06:59,870
And then we also want to go ahead and kill the player.

108
00:06:59,870 --> 00:07:02,450
So local player.

109
00:07:03,280 --> 00:07:05,440
Dot character dot humanoid.

110
00:07:05,440 --> 00:07:11,380
We want to change the state equal to the enum dot humanoid state type dot dead.

111
00:07:12,610 --> 00:07:21,880
After all of that, then we can go ahead and, um, we can wait for, I guess, the shotgun shoot sound

112
00:07:21,880 --> 00:07:22,360
to end.

113
00:07:22,360 --> 00:07:26,110
So shotgun, uh, shoot sound.

114
00:07:26,110 --> 00:07:29,770
We'll get the time length, because it's going to be the exact same as our shoot sound.

115
00:07:29,770 --> 00:07:31,630
We're going to wait for that duration.

116
00:07:32,160 --> 00:07:33,900
And I want that duration is up.

117
00:07:33,900 --> 00:07:38,580
We'll create a tween back on our pressure plate to move it back to its original position.

118
00:07:39,150 --> 00:07:48,450
So we'll refer to self dot model dot pressure plates between info dot new 0.5 seconds.

119
00:07:48,630 --> 00:07:54,390
And then we're going to set the position of the pressure plate equal to self dot model dot pressure

120
00:07:54,390 --> 00:07:57,060
plate dot position.

121
00:07:57,270 --> 00:07:59,610
And then we can offset it again with a new vector three.

122
00:07:59,610 --> 00:08:04,320
But this time we're going to move it back to its original position which is one stud upwards in the

123
00:08:04,320 --> 00:08:05,340
y direction.

124
00:08:06,460 --> 00:08:12,490
And then we play that tween and then we can set self on cooldown back to false.

125
00:08:12,520 --> 00:08:13,840
Okay cool.

126
00:08:13,960 --> 00:08:19,540
So now any time our player goes and touches a pressure plate associated with a shotgun trap, we should

127
00:08:19,540 --> 00:08:20,980
move the pressure plate downwards.

128
00:08:20,980 --> 00:08:22,450
It'll play the shoot sound.

129
00:08:22,450 --> 00:08:25,480
It'll emit a flash of light and it'll emit a particle.

130
00:08:25,480 --> 00:08:26,440
It'll kill our player.

131
00:08:26,440 --> 00:08:28,060
And then it should reset itself.

132
00:08:28,060 --> 00:08:31,510
So it's time to test to see if it works.

133
00:08:31,510 --> 00:08:37,060
So we'll play test our game here, and I'll get back to you when I find a shotgun trap.

134
00:08:38,480 --> 00:08:41,450
Alrighty, here is one of our shotgun traps right there.

135
00:08:41,450 --> 00:08:44,960
And I believe the pressure plate is this stone right here.

136
00:08:44,960 --> 00:08:50,450
So if I go and walk and touch this plate here, it should move down and the shotgun should kill me.

137
00:08:50,450 --> 00:08:51,380
So if I step on it.

138
00:08:53,720 --> 00:08:57,770
It played the sound but unfortunately looked like nothing happened.

139
00:08:58,130 --> 00:09:01,610
So let's go ahead and see exactly what we did wrong.

140
00:09:01,610 --> 00:09:04,610
I don't think we played the tween, which is our issue.

141
00:09:04,640 --> 00:09:05,060
Yeah.

142
00:09:05,060 --> 00:09:08,300
So we forgot to play the tween right here.

143
00:09:08,300 --> 00:09:13,040
Make sure you actually play the tween before you wait to listen for the tween to complete.

144
00:09:13,040 --> 00:09:14,390
Very important to do.

145
00:09:14,510 --> 00:09:15,020
Okay.

146
00:09:15,020 --> 00:09:16,250
Let's go ahead and try that again.

147
00:09:16,250 --> 00:09:21,890
But this time to make our odds easier of finding one of these shotgun traps.

148
00:09:21,890 --> 00:09:25,820
We're just going to go ahead and increase the chance of, for example, this model.

149
00:09:25,820 --> 00:09:27,440
I'll just set it to like 100.

150
00:09:27,440 --> 00:09:31,040
So that way we're guaranteed of finding a shotgun trap on the first try.

151
00:09:31,040 --> 00:09:31,640
So there we go.

152
00:09:31,640 --> 00:09:32,810
There's a shotgun trap.

153
00:09:33,330 --> 00:09:36,090
And the pressure plate should be one of these stones over here.

154
00:09:36,090 --> 00:09:37,830
So I'll just walk around over here.

155
00:09:38,610 --> 00:09:39,720
There we go.

156
00:09:39,750 --> 00:09:43,800
The pressure plate went down and then we got shotgunned in our face.

157
00:09:43,800 --> 00:09:44,790
Very cool.

158
00:09:46,090 --> 00:09:47,620
So if we go.

159
00:09:48,460 --> 00:09:49,420
And try it again.

160
00:09:49,420 --> 00:09:52,090
Hopefully it should be reset and it should kill us again.

161
00:09:52,930 --> 00:09:53,620
There we go.

162
00:09:53,620 --> 00:09:58,030
Just like that, we've got our nice little hidden shotgun trap.

163
00:09:58,480 --> 00:09:59,110
All right.

164
00:09:59,110 --> 00:10:01,360
We're done with all of the traps for our project.

165
00:10:01,360 --> 00:10:04,420
We just have a couple more things to add and we'll be finished.

166
00:10:04,420 --> 00:10:06,700
So I'll see you in the next lecture.
