00:00:00,270 --> 00:00:01,859
in this tutorial we are going to

2
00:00:01,859 --> 00:00:05,130
be using logic operations first of all go to

3
00:00:05,130 --> 00:00:08,010
numbers and select these scripts here you

4
00:00:08,010 --> 00:00:10,830
can see these are logic operations these

5
00:00:10,830 --> 00:00:13,680
have two or more operands or either

6
00:00:13,680 --> 00:00:14,580
true or false

7
00:00:15,960 --> 00:00:17,430
i will be showing you examples of

8
00:00:17,430 --> 00:00:19,920
possible combinations they are going to be

9
00:00:19,920 --> 00:00:22,470
controlling an action and then this example

10
00:00:22,470 --> 00:00:24,630
will be a sound so in sound we

11
00:00:24,630 --> 00:00:27,540
can select play sound next we need

12
00:00:27,540 --> 00:00:30,270
a control and that will be forever

13
00:00:30,450 --> 00:00:32,100
and if then

14
00:00:35,970 --> 00:00:38,730
make sure you don't forget to click

15
00:00:38,820 --> 00:00:42,990
the when green flag clicked next go

16
00:00:43,050 --> 00:00:43,920
to sensing

17
00:00:45,150 --> 00:00:47,340
and we need to select touching mouse

18
00:00:47,340 --> 00:00:47,850
pointer

19
00:00:49,350 --> 00:00:52,080
so the first example we can use

20
00:00:52,080 --> 00:00:54,300
the not we want to play a

21
00:00:54,300 --> 00:00:56,760
sound when something is not happening and

22
00:00:56,760 --> 00:00:59,100
that could be touching the other sprite

23
00:01:01,650 --> 00:01:03,660
so when it's not touching the sprite

24
00:01:03,690 --> 00:01:05,850
it will make the noise so let's

25
00:01:05,850 --> 00:01:08,070
make it touch the second sprite we

26
00:01:08,070 --> 00:01:09,630
can hear that is not making

27
00:01:12,180 --> 00:01:13,260
so it isn't touching

28
00:01:14,550 --> 00:01:16,170
the sound

29
00:01:19,980 --> 00:01:22,740
next we can use the or operation

30
00:01:23,520 --> 00:01:25,230
to this we are going to be

31
00:01:25,230 --> 00:01:30,180
comparing two values so we duplicate this so

32
00:01:30,600 --> 00:01:35,430
when touching sprite two or when touching

33
00:01:35,640 --> 00:01:37,440
the edge so

34
00:01:37,470 --> 00:01:39,750
here the condition is that script one

35
00:01:39,750 --> 00:01:41,580
will make a sound if is touching

36
00:01:41,580 --> 00:01:42,510
sprite two

37
00:01:44,670 --> 00:01:46,560
not touching one or the other then

38
00:01:53,550 --> 00:01:56,910
finally we can use the and operation

39
00:01:57,510 --> 00:01:59,550
we can use the same touching sprite

40
00:01:59,550 --> 00:02:00,000
two

41
00:02:01,380 --> 00:02:04,140
and touching edge so for the sound

42
00:02:04,140 --> 00:02:06,270
to play it has to be touching

43
00:02:06,270 --> 00:02:08,880
the sprite and the edge

44
00:02:10,199 --> 00:02:12,300
here we can hear that it only

45
00:02:13,530 --> 00:02:15,360
touching script two then it will not make

46
00:02:15,360 --> 00:02:17,520
a sound and if only touches the

47
00:02:17,520 --> 00:02:19,320
edge it will not make a sound

48
00:02:20,400 --> 00:02:22,470
after that true to make a sound
