00:00:00,510 --> 00:00:03,140
Hello and welcome to this lecture.

2
00:00:03,210 --> 00:00:09,270
In this lecture we will be creating some big game of our logic.

3
00:00:09,540 --> 00:00:18,900
The logic of the game will be that if we allow the ball to touch the bottom of the compass then the

4
00:00:18,900 --> 00:00:20,840
game is lost.

5
00:00:20,890 --> 00:00:26,670
That's the simple logic we are trying to implement in this lecture.

6
00:00:27,610 --> 00:00:34,370
At the moment the ball bounces off the fall was without nothin happening.

7
00:00:34,440 --> 00:00:41,940
What we going to do is make it bounce bounce off only the three walls bigger leaded bounce of the top

8
00:00:42,630 --> 00:00:44,530
left and the right.

9
00:00:44,850 --> 00:00:45,900
What we're going to do.

10
00:00:45,900 --> 00:00:54,810
We going to make him that if he touches the bottom of the Come that's then the game is lost so you've

11
00:00:54,810 --> 00:01:00,930
got to control the ball whether the paddle to make sure it does not touch the bottom of the compass

12
00:01:01,350 --> 00:01:03,240
anytime it touches the bottom.

13
00:01:03,480 --> 00:01:06,540
The game over are you get the popof Same.

14
00:01:06,540 --> 00:01:08,090
The game is over.

15
00:01:08,310 --> 00:01:11,730
That's what we're trying to implement here.

16
00:01:11,740 --> 00:01:17,110
All right this is the java script for the project.

17
00:01:17,490 --> 00:01:21,690
And inside the draw function here.

18
00:01:22,050 --> 00:01:26,250
This piece of code here the one highlighted here.

19
00:01:26,430 --> 00:01:36,900
This is what controls the Bunson of the ball off the four walls of the coverts we are going to amend

20
00:01:37,140 --> 00:01:42,810
this second statement here so that it does not.

21
00:01:42,840 --> 00:01:53,880
So if the ball touches the bottom of the covers we can implement alert that will show when the ball

22
00:01:53,880 --> 00:01:56,890
does the hand it will see Game over.

23
00:01:57,030 --> 00:02:06,800
So we will implement that here by amending this part of the if statement or right.

24
00:02:06,810 --> 00:02:13,030
I have already pre written the code here just to save a bit of time.

25
00:02:13,160 --> 00:02:16,690
So this is what I have done.

26
00:02:16,770 --> 00:02:21,970
This cause was from previous and I amended.

27
00:02:22,110 --> 00:02:29,840
Here we should a second block of code for Bunson the ball off the four walls of the canvas.

28
00:02:29,940 --> 00:02:42,360
So what I have done here on online 61 here have said if the variable y plus the variable D Y is less

29
00:02:42,360 --> 00:02:44,230
than the ball radius.

30
00:02:44,580 --> 00:02:52,650
I want the variable do you want to be equal to minus D y o k.

31
00:02:52,950 --> 00:03:02,370
If that's not the case then if the then I've got an ELSE IF statement which states that if the variable

32
00:03:02,370 --> 00:03:15,010
y blows a variable d y is greater than the height of the canvas minus the ball radius.

33
00:03:15,030 --> 00:03:21,660
If this condition is true thus And then I want I've also implemented.

34
00:03:21,860 --> 00:03:31,140
Be here is for when the ball touches the paddle at the moment there is no inter not in happens when

35
00:03:31,140 --> 00:03:32,340
they interact.

36
00:03:32,340 --> 00:03:40,340
So this here will create some kind of coalition detection between the ball and the paddle.

37
00:03:40,650 --> 00:03:49,370
So when the ball hits the paddle it will bounce off it and get back into the cumbersome plane area.

38
00:03:49,560 --> 00:03:53,890
That's what this bit of code here on line 65 is it.

39
00:03:53,910 --> 00:03:58,810
Ill look listen out for coalition detection between the ball and a paddle.

40
00:03:58,980 --> 00:04:02,760
So if the ball touches a puddle it will bounce back into the player era.

41
00:04:02,790 --> 00:04:08,170
That's what this bit is on online 64 sourcing.

42
00:04:08,420 --> 00:04:13,680
Yeah that's what this line 6 5 6 5 is.

43
00:04:13,680 --> 00:04:20,720
If so this is where the game logic will be implemented to determine to declare the game over.

44
00:04:21,300 --> 00:04:29,530
If the ball touches the bottom of the Come that's a tall alert.

45
00:04:29,760 --> 00:04:31,070
Game over.

46
00:04:31,240 --> 00:04:35,220
I need to reload the game to carry on again.

47
00:04:35,240 --> 00:04:43,070
All right so that's what the call is so the call the code this is a code that will be here 6 5 determines

48
00:04:43,070 --> 00:04:43,700
a coalition.

49
00:04:43,710 --> 00:04:48,470
When the ball hits the pad up to bounce off it.

50
00:04:48,510 --> 00:04:56,880
This court here from line 6 to 1 will all sorts the term in that if the ball touches the bottom of the

51
00:04:56,960 --> 00:04:59,750
comebacks this alert will.

52
00:05:00,220 --> 00:05:01,160
Displaced.

53
00:05:01,330 --> 00:05:04,460
So I'll say that and then we can see the court in that.

54
00:05:04,660 --> 00:05:05,220
Okay.

55
00:05:05,230 --> 00:05:08,510
That's the code in action at the moment.

56
00:05:08,560 --> 00:05:19,430
So if I try and control with my you can see bounces off the time it touches say bounces off the puddle

57
00:05:20,250 --> 00:05:24,160
that's me controlling it with my left or is hit the bottom.

58
00:05:24,160 --> 00:05:25,380
So game over.

59
00:05:25,570 --> 00:05:33,060
So I click okay here reloads the game and we play if will let me touch the bottom of the compass.

60
00:05:33,250 --> 00:05:38,660
It would be the game of US versus me control in the game or I missed that.

61
00:05:38,890 --> 00:05:46,000
So you can have a practice and control the game which your left some movement and the right curve some

62
00:05:46,000 --> 00:05:51,820
movement not allowing it to touch the bottom of the compass touches upon someone to come back.

63
00:05:52,060 --> 00:05:54,480
The game is over.
