00:00:00,030 --> 00:00:02,130
‫Welcome to the Project Outline and this video.

2
00:00:02,130 --> 00:00:08,630
‫I'm going to show you the end result of this chapter and I'm going to tell you how you can build this.

3
00:00:08,640 --> 00:00:10,110
‫I'm just going to do it real quick.

4
00:00:10,110 --> 00:00:16,500
‫I don't want to go into too much detail because you should be able to try to build that game yourself.

5
00:00:16,500 --> 00:00:21,270
‫By now, you have learned most of the things that you need here, and if there is something missing,

6
00:00:21,270 --> 00:00:23,280
‫then you can of course use the documentation.

7
00:00:23,280 --> 00:00:28,680
‫Or if you get stuck, you can watch the following videos in which I explain everything step by step.

8
00:00:28,680 --> 00:00:33,480
‫And if you don't feel like trying it yourself, of course you can go ahead and follow along to videos

9
00:00:33,480 --> 00:00:34,140
‫anyways.

10
00:00:34,590 --> 00:00:34,980
‫All right.

11
00:00:34,980 --> 00:00:37,200
‫So let's have a quick look at what we have here.

12
00:00:37,200 --> 00:00:40,290
‫So we have multiple different scenes.

13
00:00:40,500 --> 00:00:46,140
‫We have a game scene, a game over scene, and the main menu and the game scene is the one that we have

14
00:00:46,140 --> 00:00:54,450
‫open here, which consists of the field, which has all of those components like balls, the racquets,

15
00:00:54,450 --> 00:01:00,930
‫the two that you can see here, then the ball, and then you have the UI, which is the player, the

16
00:01:00,930 --> 00:01:03,690
‫number and the other player and his number.

17
00:01:03,690 --> 00:01:08,460
‫So these are their scores which you also have of course to program.

18
00:01:08,460 --> 00:01:15,810
‫So whenever the ball moves, the players try to hit the ball and bounce it off to the other direction.

19
00:01:15,810 --> 00:01:17,370
‫So the ball should bounce off.

20
00:01:17,370 --> 00:01:23,610
‫And then you try to bring the opponent to a situation where the ball will hit one of the sidewalls.

21
00:01:23,610 --> 00:01:29,430
‫So if it's the sidewall here on the right hand side, then player one gets a point and if it's the other

22
00:01:29,430 --> 00:01:35,010
‫side, then play two gets a point and the ball gets faster every time it hits a racket.

23
00:01:35,010 --> 00:01:40,650
‫So the difficulty goes up and up until it's not possible to hit the ball any more.

24
00:01:40,650 --> 00:01:42,840
‫So at one point the ball will be too fast.

25
00:01:42,840 --> 00:01:44,910
‫And I also have set up a maximum speed.

26
00:01:44,910 --> 00:01:50,280
‫So there will be a speed from which point the ball will not get any faster, but it's still going to

27
00:01:50,280 --> 00:01:53,640
‫be pretty much impossible to still always hit the ball.

28
00:01:53,640 --> 00:01:56,010
‫So if the player plays it well, he can beat you.

29
00:01:56,130 --> 00:02:00,690
‫So the brackets, they have a maximum speed or they have a general speed which is not increased.

30
00:02:00,690 --> 00:02:02,670
‫So the ball's increase.

31
00:02:02,730 --> 00:02:07,200
‫Increase speed is going to be a problem at one point and you just can't hit the ball anymore.

32
00:02:07,500 --> 00:02:12,510
‫Then if you hit the ball at the top side of the racket, the ball will bounce off towards the top.

33
00:02:12,510 --> 00:02:17,190
‫If you hit it at the bottom side of the racket, it will bounce off towards the bottom.

34
00:02:17,190 --> 00:02:22,110
‫So that's something where you can trick the enemy into going towards the wrong direction.

35
00:02:22,890 --> 00:02:23,280
‫All right.

36
00:02:23,280 --> 00:02:25,860
‫So that's about the basic functionality.

37
00:02:25,890 --> 00:02:28,200
‫Let's have a quick look how I solve that.

38
00:02:28,200 --> 00:02:30,450
‫So just so you know how you can do that.

39
00:02:30,450 --> 00:02:35,670
‫So I created a canvas where I have a label player one and a score player one and the same thing for

40
00:02:35,670 --> 00:02:36,690
‫the second player.

41
00:02:36,690 --> 00:02:43,260
‫And I've created scripts, of course, which update the score based on how many points the players have.

42
00:02:43,680 --> 00:02:48,540
‫Then we have the field which consists of all the elements that are part of the game.

43
00:02:48,540 --> 00:02:55,110
‫So in terms of the play mechanics, so we have all the walls and we have the rackets and of course the

44
00:02:55,110 --> 00:02:56,880
‫ball and those middle walls.

45
00:02:56,880 --> 00:03:01,770
‫I have put them in here because it looks a bit better because that just shows where the center point

46
00:03:01,770 --> 00:03:09,840
‫is and all of those walls have a 2D box collider so whenever the ball hits one of those, it will bounce

47
00:03:09,840 --> 00:03:14,640
‫off and the ball itself has a box collider as well.

48
00:03:14,640 --> 00:03:16,980
‫So it bounces off those walls.

49
00:03:16,980 --> 00:03:20,910
‫So you know that you have to use a physics material for them.

50
00:03:21,360 --> 00:03:28,080
‫You have seen those in action and one of the videos then let's have a look at the field a little more.

51
00:03:28,080 --> 00:03:30,150
‫So you have the four walls, you have the middle walls.

52
00:03:30,150 --> 00:03:32,760
‫Which are those five walls here?

53
00:03:33,510 --> 00:03:37,410
‫Then you have the rackets and the records.

54
00:03:37,410 --> 00:03:39,150
‫As you can see here, we use box colors.

55
00:03:39,150 --> 00:03:40,140
‫I created the script.

56
00:03:40,140 --> 00:03:41,430
‫We have the movement speed.

57
00:03:41,460 --> 00:03:45,690
‫They have a rigid body where I froze rotations and so forth.

58
00:03:45,690 --> 00:03:47,790
‫So that's something you will have to look into.

59
00:03:47,880 --> 00:03:55,140
‫And I have the ball here, which has two different sounds, so it plays a specific sound when it hits

60
00:03:55,140 --> 00:03:58,170
‫the wall and it plays a different sound when it hits a racket.

61
00:03:58,800 --> 00:04:03,000
‫And of course, it also needs a rigid body and a box collider.

62
00:04:03,000 --> 00:04:07,440
‫And as you can see here, I have a ball material which bounces off great.

63
00:04:07,440 --> 00:04:10,560
‫So that's about the game.

64
00:04:10,590 --> 00:04:14,100
‫And let's have a quick look at how this plays out.

65
00:04:15,190 --> 00:04:18,140
‫So this the sound played on awake.

66
00:04:18,160 --> 00:04:21,010
‫I set that up just to see if sounds are working.

67
00:04:21,580 --> 00:04:26,740
‫And then as you can see, if it bounce it, if it bounces on the left hand side, it bounces off correctly.

68
00:04:26,920 --> 00:04:28,630
‫So it bounces towards the top.

69
00:04:28,630 --> 00:04:30,010
‫And there you are.

70
00:04:30,130 --> 00:04:33,610
‫I made a point or I got one point.

71
00:04:33,610 --> 00:04:35,210
‫So now I'm just going to lose.

72
00:04:35,210 --> 00:04:42,340
‫I'm just going to move out of the way and lose the game because at five points I will move over to the

73
00:04:42,340 --> 00:04:45,040
‫game over scene and in the game over scene.

74
00:04:45,040 --> 00:04:50,110
‫I have a very simple text which says Game over and a replay button.

75
00:04:50,260 --> 00:04:52,320
‫So that we are game over and replay.

76
00:04:52,330 --> 00:04:58,120
‫And if I hit the replay button, I go back to the game and I have zero zero again and I start a completely

77
00:04:58,120 --> 00:04:58,870
‫new round.

78
00:04:59,090 --> 00:05:03,430
‫As you can see, I have an AI here, so the right racket is moving.

79
00:05:04,300 --> 00:05:06,430
‫Even if I don't do anything.

80
00:05:07,240 --> 00:05:13,740
‫So the left one is run by user input, which in my case is W and S or the arrow keys.

81
00:05:13,750 --> 00:05:19,680
‫And that one here is simply an AI which tries to follow along the position of the ball.

82
00:05:19,690 --> 00:05:22,480
‫So that's what you should try to implement.

83
00:05:23,050 --> 00:05:25,510
‫And then we have our main menu.

84
00:05:25,510 --> 00:05:29,560
‫And from that main menu you can go into the game scene as well.

85
00:05:29,560 --> 00:05:35,200
‫So you have Pong as the title and whenever you hit play you go back into the game.

86
00:05:36,950 --> 00:05:39,110
‫And that's the game scene, of course.

87
00:05:39,110 --> 00:05:42,790
‫So in the game scene, there's one thing that I haven't explained yet.

88
00:05:42,800 --> 00:05:49,970
‫The ball, it bounces off the rackets, but in my case I have implemented the functionality which makes

89
00:05:49,970 --> 00:05:51,800
‫the ball move without physics.

90
00:05:51,800 --> 00:05:52,880
‫So it bounces off.

91
00:05:52,880 --> 00:05:59,900
‫And then regarding the ball, I have used velocity here so I don't add a force to the ball, but I simply

92
00:05:59,900 --> 00:06:02,960
‫use the velocity functionality of the rigid body.

93
00:06:02,960 --> 00:06:08,450
‫So I change the velocity based on bounces for example, and it has a specific velocity at the beginning

94
00:06:08,450 --> 00:06:12,080
‫and then if it bounces off, the velocity goes towards the other direction.

95
00:06:12,080 --> 00:06:17,030
‫So when it bounces off the left racquet, the ball will go towards the right, and if it bounces off

96
00:06:17,030 --> 00:06:19,160
‫the right racquet, it will go towards the left.

97
00:06:19,220 --> 00:06:19,880
‫All right.

98
00:06:19,880 --> 00:06:22,280
‫So that should be pretty much it.

99
00:06:22,280 --> 00:06:27,710
‫As I said, I highly recommend you to try this on your own because you will learn a lot more trying

100
00:06:27,710 --> 00:06:33,500
‫to build this game yourself than just following along the videos or even just watching the videos without

101
00:06:33,500 --> 00:06:36,260
‫trying it in parallel.

102
00:06:36,470 --> 00:06:41,150
‫So go ahead and please let me know if that challenge was too difficult.

103
00:06:41,150 --> 00:06:46,520
‫If you think that there was some functionality missing that you couldn't find in the documentation or

104
00:06:46,520 --> 00:06:51,800
‫that you couldn't find online where you say, okay, this video is really necessary for me to understand

105
00:06:51,800 --> 00:06:53,480
‫what's going on and so forth.

106
00:06:53,480 --> 00:06:58,340
‫Then I can add something, of course, but otherwise you should be able to do that.

107
00:06:58,340 --> 00:07:03,980
‫And if even if something is missing, then it's even better if you find it out on your own because that

108
00:07:03,980 --> 00:07:10,280
‫will teach you to find functionality and find answers to your questions on your own.

109
00:07:10,280 --> 00:07:14,870
‫And that's something that you will definitely need whenever you want to go ahead and build your own

110
00:07:14,870 --> 00:07:16,160
‫projects in the future.

111
00:07:16,910 --> 00:07:17,360
‫All right.

112
00:07:17,360 --> 00:07:24,920
‫So please go ahead and build that or follow along the videos and see you in the next videos or the next

113
00:07:24,920 --> 00:07:25,490
‫chapter.
