1
00:00:00,480 --> 00:00:03,540
Today, I'm going to show you something called the Binder Bull event.

2
00:00:03,540 --> 00:00:09,600
And it's a way you can send information from one script to another if they're of the same type.

3
00:00:09,600 --> 00:00:16,320
So a server script to a server script, local script to a local script, and we'll go through the client

4
00:00:16,320 --> 00:00:20,640
server stuff when we do remote events, which is coming up soon.

5
00:00:22,300 --> 00:00:30,220
I'm going to demonstrate binding events by sending a message from my wave loop to my lava script, make

6
00:00:30,220 --> 00:00:31,780
an eruption go off.

7
00:00:31,780 --> 00:00:34,900
So it's going to be a server thing to a server thing, right?

8
00:00:34,900 --> 00:00:36,490
Both are server scripts.

9
00:00:36,490 --> 00:00:41,500
I'm going to go to server storage because this is going to be an event that's happening on the server

10
00:00:41,500 --> 00:00:42,220
side.

11
00:00:42,310 --> 00:00:48,610
I'm going to go to plus right here, hit a B for findable event and add it.

12
00:00:48,610 --> 00:00:50,380
It doesn't have to be in server storage.

13
00:00:50,380 --> 00:00:54,610
It could be in the workspace, but I'm going to put it here so I don't forget where it's at.

14
00:00:54,760 --> 00:01:01,630
I'm going to call this lava B for lava bind double event.

15
00:01:03,330 --> 00:01:09,600
Now I'm going to open up my wave loop, go to server script service, wave loop, and I'm going to get

16
00:01:09,600 --> 00:01:11,480
access to my BIND event.

17
00:01:11,490 --> 00:01:14,970
I put it in server storage, so I'm going to need a variable for that.

18
00:01:15,180 --> 00:01:22,290
I'll call that s for server storage game, get service server storage.

19
00:01:22,290 --> 00:01:30,330
And in there we have our bind able event and we call that larva B, I'll call the variable larva B but

20
00:01:30,330 --> 00:01:38,880
with a lowercase L, that's just my convention and we'll get our server server storage variable, wait

21
00:01:38,880 --> 00:01:45,000
for a child and then larva B make sure you see it in there.

22
00:01:45,600 --> 00:01:45,870
All right.

23
00:01:45,870 --> 00:01:49,740
Another variable I'm going to use is a wave loop counter.

24
00:01:49,740 --> 00:01:56,790
So I'm just going to do local wave loop equals zero.

25
00:01:58,460 --> 00:02:04,490
Let's go ahead and scroll down to the bottom of our while loop underneath the spawn zombies.

26
00:02:04,700 --> 00:02:07,520
I'll do a little wait right here, maybe a second.

27
00:02:07,520 --> 00:02:16,550
Just to slow down my loop and then I'm going to fire my bull event, my lava B, I'll do lava B colon

28
00:02:16,760 --> 00:02:17,630
fire.

29
00:02:17,660 --> 00:02:19,540
That's going to fire the event off.

30
00:02:19,550 --> 00:02:21,980
We'll be able to pick that up in our lava script.

31
00:02:22,010 --> 00:02:23,270
I'm going to show you in a minute.

32
00:02:23,270 --> 00:02:29,810
But just to make it interesting, I'm going to send two values with my bondable event so you can see

33
00:02:29,810 --> 00:02:31,280
how to transfer data.

34
00:02:31,400 --> 00:02:39,440
I'll send two messages, maybe lava event with an exclamation so you could see it strings going over.

35
00:02:39,590 --> 00:02:44,660
And then we're going to do our wave loop, right, just so you can see an integer going, too.

36
00:02:44,930 --> 00:02:47,960
Let's go ahead and get our wave loop.

37
00:02:48,380 --> 00:02:50,090
Do a plus equals one.

38
00:02:50,090 --> 00:02:54,080
So we're going to increment our wave loop every iteration of the loop.

39
00:02:54,110 --> 00:02:57,230
We're going to take the old wave loop and add one to it.

40
00:02:59,120 --> 00:03:02,800
Now let's go ahead and look for our lava in the workspace.

41
00:03:02,810 --> 00:03:04,260
Here's my workspace.

42
00:03:04,280 --> 00:03:05,520
Here's lava.

43
00:03:05,540 --> 00:03:09,950
I'm going to open it up and then open the eruption script.

44
00:03:10,100 --> 00:03:11,360
There we go.

45
00:03:11,510 --> 00:03:14,840
I need to get that findable event and listen to it.

46
00:03:14,840 --> 00:03:20,420
So I'm going to make a variable for server storage right here at the top.

47
00:03:20,630 --> 00:03:21,650
And I'll say.

48
00:03:22,280 --> 00:03:32,240
That's my variable convention for server storage gain colon, Get service, server storage.

49
00:03:32,420 --> 00:03:39,140
Then I'm going to get another variable for my binding event and I'm going to call Lava B because I don't

50
00:03:39,140 --> 00:03:40,490
want to get confused.

51
00:03:40,610 --> 00:03:42,770
I'm going to get that from server storage.

52
00:03:42,770 --> 00:03:46,450
I'll do a wait for child lava B.

53
00:03:47,540 --> 00:03:48,230
In this script.

54
00:03:48,230 --> 00:03:54,920
Notice that we already have our erupt function and our drain function, but down here we only call it

55
00:03:54,920 --> 00:03:55,730
one time.

56
00:03:55,730 --> 00:03:59,540
We wait 8 seconds after the game starts up, erupt.

57
00:03:59,540 --> 00:04:01,550
Wait a second drain.

58
00:04:01,550 --> 00:04:08,570
Let's wrap this in a function so that we can call it periodically with our bondable event.

59
00:04:08,570 --> 00:04:09,770
So I got rid of that.

60
00:04:09,770 --> 00:04:10,850
Wait 8 seconds.

61
00:04:10,850 --> 00:04:11,840
I don't need it.

62
00:04:11,840 --> 00:04:17,570
I'm going to do a local function activate eruption.

63
00:04:18,140 --> 00:04:21,350
I'm going to go down underneath the drain and do my end.

64
00:04:21,350 --> 00:04:24,950
I'm wrapping this in a function called Activate eruption.

65
00:04:24,950 --> 00:04:30,500
Let's go to format selection, format, document, give us some nice indents.

66
00:04:30,500 --> 00:04:32,720
And remember, we are our able event.

67
00:04:32,720 --> 00:04:34,460
We pass two parameters.

68
00:04:34,460 --> 00:04:36,530
We can capture those here.

69
00:04:36,530 --> 00:04:38,930
Let's get some variables for those parameters.

70
00:04:39,170 --> 00:04:45,770
We'll say MSG because one said something like lava vent and then a val for our integer.

71
00:04:45,770 --> 00:04:49,580
We had a wave loop coming over to and you can send more stuff than that.

72
00:04:49,580 --> 00:04:51,320
I'm just showing you how to do it.

73
00:04:51,770 --> 00:04:52,070
All right.

74
00:04:52,070 --> 00:04:56,150
So we had our lava be that was the binding event.

75
00:04:56,150 --> 00:05:01,300
We are going to listen for that event and connect to activate eruption.

76
00:05:01,310 --> 00:05:03,380
Get rid of these extra two parentheses.

77
00:05:03,380 --> 00:05:06,800
We don't need them through the magic of roadblocks.

78
00:05:06,800 --> 00:05:12,230
It's going to know to pass those variables, but let's print those variables out since we're not really

79
00:05:12,230 --> 00:05:15,710
using them, you really need to know if they're there or not.

80
00:05:15,710 --> 00:05:16,040
Right.

81
00:05:16,040 --> 00:05:23,420
So let's do a message equals MSG and then a val equals val.

82
00:05:23,420 --> 00:05:27,890
Now that we print them out, you can see that they're there and you could use that data if you wanted

83
00:05:27,890 --> 00:05:28,220
to.

84
00:05:28,250 --> 00:05:30,440
We don't need it in this example, though.

85
00:05:32,030 --> 00:05:36,980
All right, So before we test this, I'm going to go back to my wave loop and take a look at where we

86
00:05:36,980 --> 00:05:38,810
fire that findable event.

87
00:05:39,020 --> 00:05:40,310
Fire it down here.

88
00:05:40,320 --> 00:05:43,190
But we do it every loop, iteration.

89
00:05:43,190 --> 00:05:49,250
And those loops don't take very long, what, maybe 5 seconds plus a little more for some spawning.

90
00:05:49,400 --> 00:05:53,780
I want to fire this every fifth loop iteration.

91
00:05:53,780 --> 00:06:00,860
Well, I can do that because now I have a wave loop counter and I can put an F statement in here.

92
00:06:00,860 --> 00:06:12,590
I'm going to say if wave loop modulo five equals equals zero, then I'm going to fire my event.

93
00:06:13,130 --> 00:06:13,700
Right?

94
00:06:14,090 --> 00:06:25,550
So what we're doing is we are seeing if we divide wave loop by five and there's a zero remainder, then

95
00:06:25,550 --> 00:06:28,760
we're going to consider that if statement true and fire the loop.

96
00:06:28,760 --> 00:06:34,550
So it's only going to fire on zero and five and ten like that.

97
00:06:35,030 --> 00:06:36,470
Let's try it out.

98
00:06:39,080 --> 00:06:39,620
All right.

99
00:06:39,620 --> 00:06:44,390
So now let's go to the View output and we're going to check for errors.

100
00:06:45,900 --> 00:06:47,120
I will run on over.

101
00:06:47,120 --> 00:06:52,760
I'm going to get rid of that surface terrain print out that's kind of messing up my output window.

102
00:06:53,600 --> 00:06:57,320
Let's listen for our eruption and check for our message.

103
00:06:57,710 --> 00:06:58,450
Here we go.

104
00:06:58,460 --> 00:06:59,750
There's our message.

105
00:07:00,590 --> 00:07:03,980
Message Lava event value zero.

106
00:07:03,980 --> 00:07:08,240
So that was the first, the zero wavelength.

107
00:07:08,930 --> 00:07:12,020
And then it won't go again until we hit number five.

108
00:07:13,690 --> 00:07:14,680
I should pause that.

109
00:07:14,680 --> 00:07:19,150
Maybe I'll zap some zombies while we're waiting here.

110
00:07:20,590 --> 00:07:21,490
Here we go.

111
00:07:23,370 --> 00:07:24,870
And there we are.

112
00:07:24,900 --> 00:07:29,340
Message Larva Event Value five o The Zombies Getting.

113
00:07:30,310 --> 00:07:38,410
So it looks like we got a nice a nice binder bull event firing off or a lava eruption periodically.
