1
00:00:00,930 --> 00:00:03,060
in today's video tutorial we're going to

2
00:00:03,060 --> 00:00:04,530
be learning how to use the point

3
00:00:04,530 --> 00:00:07,470
toward an the point in direction blocks under the

4
00:00:07,470 --> 00:00:09,720
motion tab in the online version of

5
00:00:09,720 --> 00:00:10,410
scratch

6
00:00:11,550 --> 00:00:12,540
as you can see i have a

7
00:00:12,540 --> 00:00:14,610
new project open and i have it

8
00:00:14,970 --> 00:00:17,790
named and saved we're going to start

9
00:00:17,790 --> 00:00:19,500
off by selecting our sprites

10
00:00:20,940 --> 00:00:23,430
for today's tutorial i'm going to be

11
00:00:23,430 --> 00:00:25,650
using the shark sprite and i'm also

12
00:00:25,650 --> 00:00:28,560
going to use the fish sprite

13
00:00:32,460 --> 00:00:35,422
the purpose of using that point towards

14
00:00:35,430 --> 00:00:37,980
and the point in direction blocks is

15
00:00:37,980 --> 00:00:39,960
to have one sprite point in the

16
00:00:39,960 --> 00:00:42,600
direction of another sprite so for the

17
00:00:42,600 --> 00:00:44,880
purpose of today's tutorial what i want

18
00:00:44,970 --> 00:00:46,290
is for my shark to point in

19
00:00:46,290 --> 00:00:48,240
the direction of my fish and i

20
00:00:48,240 --> 00:00:49,830
want him to chase my fish

21
00:00:50,340 --> 00:00:51,990
so let's begin programming that

22
00:00:54,450 --> 00:00:57,270
i'm going to need under the events

23
00:00:57,300 --> 00:01:00,870
tab though when clicked block i'm going

24
00:01:00,870 --> 00:01:03,330
to need under the motion the move

25
00:01:04,170 --> 00:01:07,200
block the point into the direction and

26
00:01:07,200 --> 00:01:10,230
point towards block before we get started

27
00:01:10,230 --> 00:01:12,450
with a point towards block let's take

28
00:01:12,450 --> 00:01:13,200
a look at the

29
00:01:13,200 --> 00:01:14,670
point in direction block

30
00:01:17,160 --> 00:01:18,990
so as you can see when i

31
00:01:18,990 --> 00:01:20,880
click on this my shark is moving

32
00:01:20,880 --> 00:01:21,540
to the right

33
00:01:22,590 --> 00:01:24,180
so we're just saying what direction we

34
00:01:24,180 --> 00:01:25,890
want him to point in you can

35
00:01:25,890 --> 00:01:28,110
plug in any number between zero and

36
00:01:28,110 --> 00:01:30,720
three hundred and sixty if i plug

37
00:01:30,720 --> 00:01:33,000
in one eighty i'm saying that i

38
00:01:33,000 --> 00:01:34,920
want him to point in and in

39
00:01:34,920 --> 00:01:36,360
the direction downward

40
00:01:37,620 --> 00:01:40,110
if i put in a negative ninety

41
00:01:40,650 --> 00:01:42,690
going be pointing to the left

42
00:01:44,220 --> 00:01:45,960
and if i plug in zero is

43
00:01:45,960 --> 00:01:47,520
going to be pointing upward

44
00:01:49,650 --> 00:01:52,350
for today's tutorial i'm going to put

45
00:01:52,350 --> 00:01:53,970
him back at ninety degrees so he

46
00:01:53,970 --> 00:01:55,320
is facing the right

47
00:01:57,180 --> 00:01:59,370
now we can throw this point in direction

48
00:01:59,370 --> 00:02:01,860
block back and take a look at

49
00:02:01,860 --> 00:02:04,680
the point towards and addition of these

50
00:02:04,680 --> 00:02:06,450
blocks i need to go to control

51
00:02:06,660 --> 00:02:08,310
and i need to take out the

52
00:02:08,310 --> 00:02:10,979
wait block and also the forever block

53
00:02:12,240 --> 00:02:13,530
i'm going to be putting in my

54
00:02:13,560 --> 00:02:17,370
point towards block my move ten steps

55
00:02:17,370 --> 00:02:19,800
block and my wait one second block

56
00:02:19,830 --> 00:02:22,890
all within the forever block what i'm

57
00:02:22,890 --> 00:02:24,990
saying is that when clicked i want

58
00:02:24,990 --> 00:02:28,230
my shark to point toward my fish

59
00:02:28,770 --> 00:02:30,150
the other option would be your mouse

60
00:02:30,150 --> 00:02:31,950
pointer but for today i'm going to

61
00:02:31,950 --> 00:02:32,130
do

62
00:02:32,190 --> 00:02:34,410
fish and i want him to move

63
00:02:34,410 --> 00:02:38,040
toward the fish ten steps continuously with

64
00:02:38,040 --> 00:02:40,350
one minute or one second intervals

65
00:02:41,640 --> 00:02:43,170
now let's program our fish

66
00:02:44,760 --> 00:02:46,200
i'm going to need the wait

67
00:02:47,460 --> 00:02:51,210
the forever block under control and then

68
00:02:51,210 --> 00:02:54,000
i'm going to need that when clicked

69
00:02:54,000 --> 00:02:57,060
block and i'm also going to need

70
00:02:57,090 --> 00:03:00,570
the move block under motion

71
00:03:05,220 --> 00:03:07,200
i'm going to put my wait and

72
00:03:07,200 --> 00:03:09,330
my move blocks within the forever tab

73
00:03:10,110 --> 00:03:11,580
and as you can see with the

74
00:03:11,580 --> 00:03:13,740
fish i have my wait one second

75
00:03:13,770 --> 00:03:16,740
placed above my ten steps that's because

76
00:03:16,800 --> 00:03:18,450
when the shark is moving i want

77
00:03:18,450 --> 00:03:20,760
my fish to wait so that the

78
00:03:20,760 --> 00:03:21,810
timing between them

79
00:03:21,870 --> 00:03:25,140
is put together better let's see what

80
00:03:25,140 --> 00:03:26,730
happens with the shark when i click

81
00:03:26,730 --> 00:03:27,300
on this

82
00:03:29,880 --> 00:03:31,950
ok perfect that's exactly what i want

83
00:03:31,950 --> 00:03:32,490
him to do

84
00:03:34,290 --> 00:03:36,210
and when i click on my fish

85
00:03:38,220 --> 00:03:40,800
perfect and now let's see when we

86
00:03:40,800 --> 00:03:42,090
have them both going at the same

87
00:03:42,090 --> 00:03:44,430
time if we can achieve that chase

88
00:03:50,280 --> 00:03:50,790
perfect

89
00:03:52,080 --> 00:03:53,790
you also have the option of course

90
00:03:53,790 --> 00:03:56,400
to change the timing for my fish

91
00:03:56,580 --> 00:03:58,350
i want him to go faster than

92
00:03:58,350 --> 00:04:00,330
the shark i'm going to change the

93
00:04:00,330 --> 00:04:02,190
timing from one second to point two

94
00:04:02,190 --> 00:04:05,010
five and then i'm going to change

95
00:04:05,010 --> 00:04:07,410
the timing from a shark to point

96
00:04:07,410 --> 00:04:09,630
fifties there is a little slower than

97
00:04:09,630 --> 00:04:11,820
my fish let's take a look

98
00:04:17,279 --> 00:04:19,682
and that concludes our video tutorial for

99
00:04:19,682 --> 00:04:20,070
it today
