00:00:00,780 --> 00:00:05,580
Today I'm going to introduce a wave loop so that things can happen periodically.

2
00:00:05,580 --> 00:00:10,800
And also I want to introduce module scripts, which are scripts that can be called from other scripts.

3
00:00:10,800 --> 00:00:15,080
So we're going to use them as a code library, which is really, really useful.

4
00:00:15,090 --> 00:00:19,650
So let's go over here to server script service, open it up, see what we got in there.

5
00:00:19,650 --> 00:00:22,260
Well, we do have this spanner in here.

6
00:00:22,260 --> 00:00:23,850
That's a regular script.

7
00:00:23,850 --> 00:00:29,610
I'm going to hit the plus sign and I'm going to add a module script, write, module script.

8
00:00:29,610 --> 00:00:33,540
Make sure you get that right, because a regular script is not going to work if you're trying it.

9
00:00:33,930 --> 00:00:37,860
All right, this module script, I'm going to call session utils.

10
00:00:39,570 --> 00:00:41,850
It's going to be a library of functions.

11
00:00:41,850 --> 00:00:42,290
Whoops.

12
00:00:42,900 --> 00:00:45,090
But I'm going to call from another script now.

13
00:00:45,090 --> 00:00:46,140
Session utils.

14
00:00:46,260 --> 00:00:48,120
Let me make this bigger so you can see it.

15
00:00:49,970 --> 00:00:57,860
Is going to have a table inside it when we require our session utils in another script or include it.

16
00:00:57,860 --> 00:01:02,630
If you're more familiar with that terminology, we're going to get a table returned.

17
00:01:02,630 --> 00:01:05,540
It's going to have our functions stored in the table.

18
00:01:05,540 --> 00:01:06,650
Pretty cool.

19
00:01:06,680 --> 00:01:14,150
I'm going to call this table utils and if you change the name here, you have to change the name down

20
00:01:14,150 --> 00:01:14,750
here.

21
00:01:14,750 --> 00:01:18,980
It does not have to match this one obviously because I have session utils.

22
00:01:18,980 --> 00:01:19,550
Right.

23
00:01:20,000 --> 00:01:26,810
And let's go and make a function that we're going to store in this utils table that we can use someplace

24
00:01:26,810 --> 00:01:27,380
else.

25
00:01:27,380 --> 00:01:38,090
So I'm going to say function not local because it's not local to my script, utils, colon, start wav

26
00:01:39,140 --> 00:01:48,470
and then just go put a little print statement in here, print wav starting if I could spell it right.

27
00:01:48,470 --> 00:01:49,880
There we go.

28
00:01:49,880 --> 00:01:51,650
It's pretty simple to start off.

29
00:01:51,650 --> 00:01:57,890
Now let's go to server script service on a close Z spanner so it gets out of the way, but in server

30
00:01:57,890 --> 00:01:59,570
script servers are going to hit the plus.

31
00:01:59,600 --> 00:02:04,730
Now I'm going to get a regular script right, or a server script, we call it.

32
00:02:04,730 --> 00:02:07,880
It just says script, but it runs on the server.

33
00:02:08,030 --> 00:02:09,980
I'm going to call this wave loop.

34
00:02:12,720 --> 00:02:13,050
All right.

35
00:02:13,050 --> 00:02:18,270
And in wave loop, I want to require my session utils.

36
00:02:18,270 --> 00:02:20,730
I want to import it or include it.

37
00:02:20,760 --> 00:02:23,100
Whatever programming language you come from.

38
00:02:23,100 --> 00:02:24,570
Or maybe not at all.

39
00:02:24,570 --> 00:02:25,020
Right.

40
00:02:25,020 --> 00:02:28,080
So they use require in node.js.

41
00:02:28,080 --> 00:02:30,870
So you like that if you want to do Node.js.

42
00:02:31,050 --> 00:02:31,410
All right.

43
00:02:31,410 --> 00:02:35,010
So I'm going to require and I need to find it.

44
00:02:35,010 --> 00:02:38,760
So we have this top level game object in there.

45
00:02:38,760 --> 00:02:43,080
We have server script service, that's this right here.

46
00:02:43,080 --> 00:02:48,780
And then I could do this dot session, Utils Walla, I got my utils.

47
00:02:48,780 --> 00:02:52,770
This is going to be the table that's going to have all my functions in there.

48
00:02:52,770 --> 00:03:02,430
So let me do a little loop here while true do and then I'll do a little weight statement.

49
00:03:02,430 --> 00:03:10,020
You don't want to crash your machine and we'll go utils colon start wav.

50
00:03:10,020 --> 00:03:11,460
Let's see what we got.

51
00:03:11,460 --> 00:03:19,140
We should see this print statement firing once a second, so we'll hit the play button.

52
00:03:19,140 --> 00:03:22,620
Let's go to The View so we can take a look at our output window.

53
00:03:23,720 --> 00:03:24,710
And there we go.

54
00:03:24,710 --> 00:03:29,120
Waves started so you could see that it's printing over and over and over again.

55
00:03:30,060 --> 00:03:30,710
Oh, look at that.

56
00:03:30,720 --> 00:03:31,860
We had our eruption.

57
00:03:31,860 --> 00:03:33,480
We should put that in the wave.

58
00:03:33,510 --> 00:03:34,590
That would be pretty cool.
