1
00:00:04,680 --> 00:00:12,330
‫If we have a look at the UI of fruit ninja, we can see that we have a well, a score, a best score,

2
00:00:12,330 --> 00:00:14,220
‫and then we have a timer that runs up.

3
00:00:14,220 --> 00:00:17,700
‫And that's what we need to add to our game as well, of course.

4
00:00:17,700 --> 00:00:23,760
‫So let's go ahead and create a new object first and call it game manager.

5
00:00:25,830 --> 00:00:27,930
‫And in here we add a script.

6
00:00:27,930 --> 00:00:35,190
‫So let's create a new script and call that, and we assign a new script to that game manager.

7
00:00:35,190 --> 00:00:41,010
‫So let's create a new script here in our scripts folder and call that game manager.

8
00:00:41,910 --> 00:00:45,780
‫Now let's drag the game manager into our game manager script.

9
00:00:47,010 --> 00:00:51,600
‫Now let's direct the game manager script to our game manager and edit that.

10
00:00:53,520 --> 00:00:57,960
‫Now what our game manager will do for now is count the score.

11
00:00:57,960 --> 00:01:02,580
‫So let's create a method and several variables for that.

12
00:01:02,610 --> 00:01:09,330
‫First of all, we will need an integer which will have the score value assigned to it, and then we

13
00:01:09,330 --> 00:01:11,400
‫will need a text object.

14
00:01:11,400 --> 00:01:19,380
‫And in order to work with text we need to add unity engine start UI.

15
00:01:19,980 --> 00:01:22,050
‫So the namespace, the unity engine, the UI.

16
00:01:22,080 --> 00:01:32,280
‫Now we can access the text, class, public text and we're going to call that score text and let's create

17
00:01:32,280 --> 00:01:35,280
‫a method which will simply increase our score.

18
00:01:35,280 --> 00:01:46,770
‫So public void, increase score, and now let's increase the score by, let's say two each time that

19
00:01:46,770 --> 00:01:51,090
‫somebody calls this method or any class calls this method.

20
00:01:52,440 --> 00:01:54,330
‫So increase by two.

21
00:01:55,500 --> 00:01:57,960
‫And then also we want to set the score text.

22
00:01:57,960 --> 00:02:03,060
‫So each time the score is increased, we want to update the text variable, of course, as well.

23
00:02:03,060 --> 00:02:05,520
‫So score to string.

24
00:02:09,120 --> 00:02:13,950
‫All right, now let's save that script and let's go back to Unity in here.

25
00:02:13,950 --> 00:02:18,930
‫We will create a new object and I'm going to call that UI.

26
00:02:19,830 --> 00:02:21,750
‫So let's change the name of the game object.

27
00:02:21,750 --> 00:02:22,890
‫Let's call it UI.

28
00:02:22,890 --> 00:02:31,200
‫And now let's add a UI text here that will create the canvas and I'm going to drag the canvas into the

29
00:02:31,200 --> 00:02:32,610
‫UI game object.

30
00:02:33,180 --> 00:02:40,200
‫And what I want to use here is that our canvas scalar doesn't have a constant pixel size, but that

31
00:02:40,200 --> 00:02:42,270
‫it scales with the screen size.

32
00:02:42,450 --> 00:02:51,030
‫And we can set the resolution to, for example, 800 times 800 or 19, 20 times 1080, whatever you

33
00:02:51,030 --> 00:02:51,960
‫want to have.

34
00:02:52,230 --> 00:02:55,320
‫So for now, we will just have the text in there.

35
00:02:55,320 --> 00:03:03,330
‫So let's a look what this looks like currently and we don't see the text even so let's manage that.

36
00:03:04,350 --> 00:03:05,430
‫Let's go to our canvas.

37
00:03:05,430 --> 00:03:06,030
‫There you are.

38
00:03:06,030 --> 00:03:10,110
‫And you see that our text is currently not even inside of our game.

39
00:03:10,110 --> 00:03:18,510
‫Let's see, our UI element should be reset and now we can change the position of our text.

40
00:03:18,750 --> 00:03:22,110
‫I want my score text to be at the top left side of my UI.

41
00:03:22,110 --> 00:03:27,690
‫So let's zoom in a little bit and let's change the rect transform to the top left.

42
00:03:27,690 --> 00:03:29,340
‫That will be the anchor preset.

43
00:03:29,700 --> 00:03:35,160
‫So that means from this perspective on the values of X and Y are calculated.

44
00:03:35,160 --> 00:03:37,110
‫So let's just choose zero zero.

45
00:03:37,110 --> 00:03:41,640
‫And you can see that our text now is at this top left corner.

46
00:03:42,180 --> 00:03:47,730
‫Now, good values would be, for example, 100 and -75.

47
00:03:48,600 --> 00:03:53,100
‫And maybe let's change the size of our text as well.

48
00:03:53,100 --> 00:03:54,690
‫So this will be the score text.

49
00:03:54,690 --> 00:04:04,050
‫So let's maybe enter a value like zero in here and change the name of it.

50
00:04:04,050 --> 00:04:06,300
‫So I'm going to call it score text.

51
00:04:07,350 --> 00:04:11,340
‫Now, of course, the font size is a little bit too small, so let's change that.

52
00:04:11,400 --> 00:04:14,760
‫Let's go with, let's say 120.

53
00:04:15,180 --> 00:04:16,740
‫And as you can see now, it disappears.

54
00:04:16,740 --> 00:04:18,510
‫So we don't see the number anymore.

55
00:04:18,510 --> 00:04:21,180
‫And that has to do with the overflow.

56
00:04:21,180 --> 00:04:28,860
‫So if you add horizontal and vertical overflow, what that will do is it will show the number no matter

57
00:04:28,860 --> 00:04:29,340
‫what.

58
00:04:30,150 --> 00:04:35,550
‫Now, no matter what the size here, for example, for the width and height is for this object.

59
00:04:36,840 --> 00:04:39,210
‫So that's how it will currently look like.

60
00:04:39,210 --> 00:04:42,810
‫Maybe it's not the perfect position to play around with it.

61
00:04:42,810 --> 00:04:45,240
‫Maybe so let's drag it up there.

62
00:04:46,050 --> 00:04:50,820
‫So the wide position of zero, I think that should be around.

63
00:04:50,820 --> 00:04:51,510
‫Fine.

64
00:04:51,510 --> 00:04:53,970
‫Now let's change the color of the text.

65
00:04:54,300 --> 00:04:58,860
‫Let's make it an orange ish or orange ish color.

66
00:05:01,060 --> 00:05:01,930
‫Like that.

67
00:05:02,770 --> 00:05:03,570
‫Now let's see.

68
00:05:03,580 --> 00:05:04,750
‫There is zero.

69
00:05:04,780 --> 00:05:07,270
‫Of course, our background doesn't look as nice anymore.

70
00:05:07,300 --> 00:05:10,600
‫We need to change the background of our game.

71
00:05:12,460 --> 00:05:14,410
‫But at least we have our score text.

72
00:05:14,410 --> 00:05:20,680
‫So now let's duplicate that text and call this one high score text.

73
00:05:22,180 --> 00:05:24,750
‫And now let's change that high score text.

74
00:05:24,760 --> 00:05:30,500
‫Let's drag it to the bottom and let's enter best colon zero.

75
00:05:30,520 --> 00:05:33,040
‫And as you can see, this is, of course, way too big.

76
00:05:33,040 --> 00:05:38,230
‫So let's scale that down to maybe 36.

77
00:05:40,980 --> 00:05:42,270
‫That looks much better.

78
00:05:42,380 --> 00:05:44,860
‫So look in the game best zero.

79
00:05:45,020 --> 00:05:50,790
‫Okay, for now, let's maybe change the background of our main camera.

80
00:05:50,790 --> 00:05:51,690
‫So now it's.

81
00:05:52,920 --> 00:06:00,090
‫This color, this orange brownish color, and maybe this will look better now.

82
00:06:00,090 --> 00:06:00,630
‫It's fine.

83
00:06:00,630 --> 00:06:02,190
‫I think that's better for now.

84
00:06:02,820 --> 00:06:09,060
‫Now, in order to make our number look a little bit cooler, what we can do is add an outline so you

85
00:06:09,060 --> 00:06:11,070
‫can go here to UI.

86
00:06:11,400 --> 00:06:19,920
‫So add component, then UI effects and then you'll find outline here that will do is it will add an

87
00:06:19,920 --> 00:06:26,310
‫outline to your game so you could or to you to your text and you could do that like this.

88
00:06:26,310 --> 00:06:34,170
‫As you can see now you can create an edge, an outline edge to your score text, your high score text.

89
00:06:34,170 --> 00:06:41,070
‫Here, the white one would make sense if the main camera, for example, would be a bright color, then

90
00:06:41,070 --> 00:06:42,900
‫a black one would look better.

91
00:06:43,410 --> 00:06:49,920
‫So if it's like this color, for example, then maybe the score should have an effect.

92
00:06:49,920 --> 00:06:51,510
‫Color of black.

93
00:06:52,300 --> 00:06:57,520
‫So I think that looks much better than the high score text should get one as well.

94
00:06:57,520 --> 00:07:02,980
‫So let's add in UI effects outline.

95
00:07:04,150 --> 00:07:06,760
‫And as you can see now, they look much better.

96
00:07:07,600 --> 00:07:12,340
‫All right, so now let's implement our score text in our code.

97
00:07:12,340 --> 00:07:19,300
‫So our game manager already expects a score text so we can drag that in there and our current score

98
00:07:19,300 --> 00:07:20,200
‫will be zero.

99
00:07:20,200 --> 00:07:23,680
‫So if we set that to five, for example, let's have a look what happens.

100
00:07:25,350 --> 00:07:27,690
‫Actually, let's set that to five endgame.

101
00:07:28,230 --> 00:07:30,000
‫As you can see, nothing happens yet.

102
00:07:30,000 --> 00:07:33,180
‫So we will need to add score.

103
00:07:33,180 --> 00:07:41,880
‫So which means we will need to call this method here, this increased score method in our fruit script.

104
00:07:41,880 --> 00:07:48,540
‫So whenever we create a sliced fruit, that means we had a we got an additional score.

105
00:07:48,960 --> 00:07:54,150
‫So in order to do that, let's add find object of type

106
00:07:57,060 --> 00:08:02,190
‫game manager and increase the score.

107
00:08:02,760 --> 00:08:07,860
‫So this will now increase the score every time that we slice a fruit.

108
00:08:09,090 --> 00:08:09,450
‫All right.

109
00:08:09,450 --> 00:08:10,620
‫So now let's test it.

110
00:08:10,710 --> 00:08:11,790
‫Let's start the game.

111
00:08:13,880 --> 00:08:17,030
‫And let's slice through our fruits.

112
00:08:17,030 --> 00:08:20,630
‫And as you can see, our score is increased by two every time.

113
00:08:21,290 --> 00:08:27,590
‫And maybe we want to have different values based on the fruit that we have sliced currently only slice

114
00:08:27,620 --> 00:08:31,130
‫oranges, but maybe we want to slice other objects as well.

115
00:08:31,160 --> 00:08:34,460
‫Then we would also want to have different values, for example.

116
00:08:34,460 --> 00:08:37,340
‫So currently let's just assign three here.

117
00:08:37,370 --> 00:08:43,070
‫Now of course, we will get an error because the game manager itself doesn't know what these three should

118
00:08:43,070 --> 00:08:43,450
‫do.

119
00:08:43,460 --> 00:08:53,840
‫So let's add an int points in here and now instead of saying score plus two plus equal to, we just

120
00:08:53,840 --> 00:08:57,260
‫increase it by whatever points is delivered.

121
00:08:57,350 --> 00:09:00,710
‫So in our case now it will be three.

122
00:09:00,710 --> 00:09:04,940
‫So every time we run or we slice a fruit, we will get three points now.

123
00:09:04,940 --> 00:09:07,810
‫So let's check that out real quick, if that's true.

124
00:09:07,820 --> 00:09:08,660
‫So.

125
00:09:09,720 --> 00:09:11,610
‫Let's slice a fruit.

126
00:09:11,610 --> 00:09:12,450
‫And there we are.

127
00:09:12,450 --> 00:09:14,280
‫We get three points.

128
00:09:15,360 --> 00:09:15,780
‫All right.

129
00:09:15,780 --> 00:09:22,440
‫Now, next, we need to add a functionality that stops the game because now we can play the game endlessly

130
00:09:22,440 --> 00:09:26,130
‫and will constantly get points and there is no punishment for any behavior.

131
00:09:26,130 --> 00:09:29,160
‫And of course, we want to change that in fruit ninja.

132
00:09:29,160 --> 00:09:31,530
‫That's usually done by the bomb or by the timer.

133
00:09:31,530 --> 00:09:33,750
‫So if the timer runs up, the game will be stopped.

134
00:09:33,750 --> 00:09:36,630
‫Or if we hit a bomb, then the timer stops as well.

135
00:09:36,630 --> 00:09:39,330
‫So let's add the bomb to our game.

136
00:09:39,330 --> 00:09:40,950
‫So let's go to the scene view.

137
00:09:40,980 --> 00:09:44,280
‫Let's open our models folder.

138
00:09:44,280 --> 00:09:45,540
‫And here we had the bomb.

139
00:09:45,540 --> 00:09:49,620
‫All right, so now let's go into a scene view and let's drag the bomb into our game.

140
00:09:49,620 --> 00:09:52,320
‫Well, actually, it's too big, so let's get rid of it again.

141
00:09:52,320 --> 00:09:56,100
‫So let's delete the bomb and go to our bomb model.

142
00:09:56,100 --> 00:10:00,330
‫Now let's change the scale factor to 0.3 and apply that.

143
00:10:00,540 --> 00:10:02,250
‫And now we can drag the bomb in.

144
00:10:02,250 --> 00:10:04,260
‫And I think that size is much better.

145
00:10:04,260 --> 00:10:06,480
‫So now let's add some components to it.

146
00:10:06,480 --> 00:10:15,210
‫For example, a physics 2D, rigid body and a physics to DX box or actually circle collider.

147
00:10:15,210 --> 00:10:17,280
‫Here, this should be fine.

148
00:10:17,280 --> 00:10:19,950
‫All right, the circle collider fits well, I think.

149
00:10:21,990 --> 00:10:24,780
‫All right, so what do we want to happen if we hit a bump?

150
00:10:24,780 --> 00:10:30,210
‫Well, we want to pause the game and show the game over screen or something like that.

151
00:10:30,210 --> 00:10:33,540
‫So let's add a script to our bomb.

152
00:10:34,410 --> 00:10:40,770
‫So I'm going to add a new script and I'm going to call that one bomb script or actually just bomb.

153
00:10:41,040 --> 00:10:44,490
‫And now let's open that bomb script up in here.

154
00:10:44,490 --> 00:10:51,180
‫We will add an on trigger enter to DX method.

155
00:10:51,180 --> 00:10:56,970
‫So whenever we hit the bomb, we want to see if the blade hit us.

156
00:10:56,970 --> 00:10:59,670
‫So blade b equals collision

157
00:11:01,890 --> 00:11:02,700
‫dot.

158
00:11:02,790 --> 00:11:12,510
‫Actually, it's not this collision, it's that collision here collision dot get component and blade.

159
00:11:12,510 --> 00:11:18,750
‫So what that means, well, we've seen that code already, but what that means if the object that was

160
00:11:18,750 --> 00:11:23,400
‫triggered or hit triggered us, if that's the blade, then do something.

161
00:11:23,400 --> 00:11:26,040
‫And if it's not the blade, then return.

162
00:11:26,040 --> 00:11:36,690
‫So if not B return, but if it is B, then we want to find object of type game manager.

163
00:11:36,690 --> 00:11:40,470
‫So then we want to access our game manager and call a method from him.

164
00:11:40,470 --> 00:11:43,080
‫So let's say on bomb hit.

165
00:11:43,080 --> 00:11:48,960
‫So whenever we hit the bump now it complains that there is no method called on bomb hit and we'll find

166
00:11:48,960 --> 00:11:54,330
‫that method in our game manager or we need to create that method and the game manager.

167
00:11:54,330 --> 00:12:03,720
‫So let's create that method void on bomb hit and that should be public so that we can access it from

168
00:12:03,720 --> 00:12:04,170
‫outside.

169
00:12:04,170 --> 00:12:08,520
‫Of course, for now, let's just say bump was hit.

170
00:12:08,520 --> 00:12:13,740
‫So debug log bomb hit.

171
00:12:18,200 --> 00:12:19,550
‫So let's save that script.

172
00:12:19,550 --> 00:12:21,380
‫Let's save the bomb script as well.

173
00:12:21,380 --> 00:12:24,680
‫Now we see the error is not there anymore.

174
00:12:26,440 --> 00:12:27,410
‫Now let's test that.

175
00:12:27,410 --> 00:12:28,580
‫So let's go back.

176
00:12:29,750 --> 00:12:33,950
‫Actually, let's drag the bomb script into our script folder while we're added.

177
00:12:33,950 --> 00:12:38,900
‫And now let's run the game and let's see if I hit a bomb.

178
00:12:39,140 --> 00:12:46,130
‫Actually, the bomb was moving too fast, so I'm going to push it to the top so I can actually what

179
00:12:46,130 --> 00:12:49,370
‫I can do is for now, deactivate the.

180
00:12:50,960 --> 00:12:51,920
‫Gravity.

181
00:12:52,670 --> 00:12:55,160
‫So let's say gravity scale zero.

182
00:12:57,800 --> 00:12:59,330
‫And let's see what happens.

183
00:13:01,270 --> 00:13:05,530
‫And I can drag or hit the bomb.

184
00:13:05,560 --> 00:13:11,110
‫Actually, nothing will happen, of course, as our trigger as there is no trigger in the circle collider.

185
00:13:11,140 --> 00:13:14,200
‫Now let's see once again what happens now.

186
00:13:15,730 --> 00:13:20,380
‫And as you can see, Bob hit is called Every Time that I Go Through the bomb.

187
00:13:20,410 --> 00:13:20,830
‫All right.

188
00:13:20,830 --> 00:13:24,040
‫So now we can change the gravity scale to one again.

189
00:13:24,340 --> 00:13:26,230
‫That was just for testing purposes.

190
00:13:27,400 --> 00:13:29,590
‫And now our bomb should work.

191
00:13:29,620 --> 00:13:32,290
‫Now, what we want to do is we want to.

192
00:13:33,690 --> 00:13:36,120
‫Stop the game whenever that happens.

193
00:13:36,450 --> 00:13:43,230
‫So we can just say time dot time scale is equal to zero.

194
00:13:43,470 --> 00:13:45,270
‫That will just stop the game.

195
00:13:47,230 --> 00:13:54,670
‫So this time, the time scale is in general a functionality that allows you to reduce the speed of your

196
00:13:54,670 --> 00:13:55,180
‫game.

197
00:13:55,180 --> 00:14:00,010
‫So zero means there is no speed at all, which means there is no movement and you stop the game.

198
00:14:00,010 --> 00:14:02,340
‫And one would be you have the normal speed.

199
00:14:02,350 --> 00:14:08,110
‫So timescale one is the default value and timescale zero is, for example, to stop the game.

200
00:14:08,110 --> 00:14:15,070
‫So let's save that script and check that out again and let's see if I can hit the bomb quickly enough.

201
00:14:16,100 --> 00:14:17,660
‫In order to stop the game.

202
00:14:18,170 --> 00:14:24,230
‫And as you can see, I dashed through it and my bombs were actually my fruits stopped and the bomb stopped

203
00:14:24,230 --> 00:14:24,800
‫as well.

204
00:14:26,970 --> 00:14:29,280
‫All right, now we only have one bump.

205
00:14:29,280 --> 00:14:34,350
‫So this one bump is fine, but we want to randomly spawn bombs as well.

206
00:14:34,410 --> 00:14:38,820
‫And in order to do that, we need to go back to our sponsor game object.

207
00:14:38,820 --> 00:14:40,400
‫So our script better set.

208
00:14:40,410 --> 00:14:42,420
‫So let's go to the sponsor script.

209
00:14:43,970 --> 00:14:51,260
‫And currently we only have one fruit to spawn, so we can only spawn one type of fruit.

210
00:14:51,270 --> 00:14:58,250
‫In this case, it's an orange, but what we want to have is to be able to spawn oranges, spawn bananas,

211
00:14:58,250 --> 00:15:02,210
‫spawn whatever we think of, and also spawn bombs.

212
00:15:02,210 --> 00:15:10,460
‫And in order to do that, we need to change this fruit to spawn to an array, which is an array of game

213
00:15:10,460 --> 00:15:10,940
‫objects.

214
00:15:10,940 --> 00:15:19,190
‫So let's add the square brackets and let's change that to objects to spawn, because it's not just fruits,

215
00:15:19,190 --> 00:15:20,810
‫it's objects in general.

216
00:15:20,840 --> 00:15:27,110
‫Now, of course, here we get an error because we try to spawn one simple fruit and this method is not

217
00:15:27,110 --> 00:15:28,130
‫available anymore.

218
00:15:28,130 --> 00:15:35,660
‫So what we need to do is we need to randomly create a game object, which is either a bump or which

219
00:15:35,660 --> 00:15:36,950
‫is another fruit.

220
00:15:36,950 --> 00:15:39,920
‫And then we simply say, okay, spawn that.

221
00:15:40,970 --> 00:15:42,410
‫So let's go ahead and do that.

222
00:15:42,410 --> 00:15:52,010
‫Let's create a game object, let's call the G0 and set that to NULL and then we have a random value.

223
00:15:52,010 --> 00:15:54,950
‫So let's create the random value range.

224
00:15:55,190 --> 00:15:59,480
‫We want to randomly create different kind of fruits or different kind of game objects.

225
00:15:59,480 --> 00:16:04,340
‫For example, the bomb should spawn less often than something else.

226
00:16:05,630 --> 00:16:14,300
‫So what I'm going to say here, if P is lower than ten, because the value can be between zero and 100.

227
00:16:14,300 --> 00:16:16,670
‫So if it's lower than ten, then I want to spawn a bump.

228
00:16:16,670 --> 00:16:22,010
‫So the chance of the bump is roughly 10% or the chance of a bond bump to spawn.

229
00:16:22,010 --> 00:16:27,500
‫So I'm just going to say G oh is objects to spawn at the position of zero.

230
00:16:27,770 --> 00:16:30,750
‫So now of course I'll have to take care of this.

231
00:16:30,750 --> 00:16:43,610
‫So I need to assign the bump at the position of zero and otherwise so else I want to set go with objects

232
00:16:43,610 --> 00:16:57,290
‫to spawn with a random range between one and objects to spawn length.

233
00:16:57,620 --> 00:17:01,130
‫So that will do is with the chance of 10%.

234
00:17:01,370 --> 00:17:03,230
‫I'm going to create a bump.

235
00:17:05,040 --> 00:17:08,730
‫And with a chance of 90%, I'm going to create a different kind of fruit.

236
00:17:08,730 --> 00:17:15,300
‫And here, of course, I need to use curly brackets because this is an index that we are trying to assign

237
00:17:15,300 --> 00:17:16,110
‫this to.

238
00:17:18,060 --> 00:17:24,720
‫So, once again, 10% chance, it's a bump and 90% chance, it's something random out of all of the

239
00:17:24,720 --> 00:17:28,320
‫other objects to spawn that we have assigned.

240
00:17:28,620 --> 00:17:32,190
‫And now, of course, we don't instantiate a fruit to spawn anymore.

241
00:17:32,190 --> 00:17:34,860
‫We instantiate that game object.

242
00:17:35,250 --> 00:17:40,320
‫Now, of course, you could you could create an object to spawn what you call fruits to spawn.

243
00:17:40,320 --> 00:17:47,520
‫And then you could, of course, say public game object bump, and then you could just assign the bump

244
00:17:47,520 --> 00:17:52,710
‫in here and you could now change gold to be Bob here.

245
00:17:54,930 --> 00:17:56,120
‫That would be an option.

246
00:17:56,130 --> 00:17:59,550
‫Of course, your range would be from zero to somewhere.

247
00:17:59,670 --> 00:18:00,870
‫That would be another option.

248
00:18:00,870 --> 00:18:08,220
‫Maybe that's even a slightly more intuitive option because the bump is a very specific kind of fruit

249
00:18:08,220 --> 00:18:11,340
‫and whatever else we add, we can add as we like.

250
00:18:11,340 --> 00:18:16,680
‫Because the other way that I was just showing you, we would always have to be careful that we assign

251
00:18:16,680 --> 00:18:18,300
‫the bump to the very first spot.

252
00:18:18,300 --> 00:18:21,210
‫And we know that because we have created the code.

253
00:18:21,210 --> 00:18:27,360
‫But if somebody else starts to run the code or starts to edit the code, he might be confused about

254
00:18:27,360 --> 00:18:27,720
‫that.

255
00:18:28,440 --> 00:18:28,800
‫All right.

256
00:18:28,800 --> 00:18:32,370
‫So now we make sure, okay, it's going to be the bob here.

257
00:18:32,520 --> 00:18:33,840
‫Now, let's save that

258
00:18:36,510 --> 00:18:38,760
‫and let's go back to Unity.

259
00:18:38,790 --> 00:18:41,130
‫There you will see what's happening.

260
00:18:41,130 --> 00:18:45,140
‫So our sponsor should get fruit to spawn.

261
00:18:45,150 --> 00:18:46,740
‫Currently, it's just the orange.

262
00:18:47,700 --> 00:18:54,120
‫And after a couple of seconds, it should change from fruit spawn to objects to spawn and bump.

263
00:18:54,150 --> 00:18:54,510
‫All right.

264
00:18:54,510 --> 00:18:57,000
‫So there's the bump and the objects to spawn.

265
00:18:57,000 --> 00:19:01,080
‫And I'm just going to say, currently, it's going to be one object that I want to spawn.

266
00:19:01,350 --> 00:19:06,210
‫And now let's go to our prefabs and let's drag the orange in there.

267
00:19:08,070 --> 00:19:12,720
‫So spawn direct the orange in here.

268
00:19:18,350 --> 00:19:19,670
‫And now about the bomb.

269
00:19:20,750 --> 00:19:22,820
‫Actually, we don't have a bomb prefab yet.

270
00:19:22,820 --> 00:19:24,340
‫So let's create a bomb prefab.

271
00:19:24,350 --> 00:19:26,840
‫Let's drag the bomb into our prefabs folder.

272
00:19:26,840 --> 00:19:31,940
‫And now let's drag that bomb into our spotter.

273
00:19:35,530 --> 00:19:42,010
‫In order to test that, maybe we should set the value to 50 here so that there is a 5050 chance that

274
00:19:42,010 --> 00:19:43,750
‫there is a bump that comes up.

275
00:19:44,050 --> 00:19:47,650
‫So just to see whether there are bumps or the bumps come in general.

276
00:19:48,940 --> 00:19:49,330
‫All right.

277
00:19:49,330 --> 00:19:52,330
‫So there's a bump, oranges, bombs, oranges, bombs.

278
00:19:52,330 --> 00:19:58,520
‫And if I hit an or a bump, well, I hit it outside, but I hit the bump and now, boom, the game stops.

279
00:19:58,540 --> 00:20:03,160
‫So now let's see if we well, let's set that back to ten.

280
00:20:03,190 --> 00:20:04,030
‫That's better.

281
00:20:04,690 --> 00:20:08,500
‫And now the chance that a bomb comes up will only be 10%.

282
00:20:08,530 --> 00:20:09,220
‫Of course.

283
00:20:14,100 --> 00:20:17,490
‫And as you see, oranges, oranges, oranges.

284
00:20:18,090 --> 00:20:20,670
‫And then we get points all the time.

285
00:20:21,520 --> 00:20:24,180
‫At one point, a bomb might come up.

286
00:20:24,450 --> 00:20:27,330
‫So far, none was there.

287
00:20:29,400 --> 00:20:30,180
‫Actually.

288
00:20:30,180 --> 00:20:30,690
‫Come on.

289
00:20:30,690 --> 00:20:31,500
‫Where's the bomb?

290
00:20:33,270 --> 00:20:35,370
‫As you can see, that's the thing with chances, right?

291
00:20:35,910 --> 00:20:37,590
‫Chances are just chance.

292
00:20:37,590 --> 00:20:43,230
‫So it could happen that I get a gazillion oranges here before I get a bump.

293
00:20:43,770 --> 00:20:46,350
‫Well, the probability is very low and there is a bomb.

294
00:20:46,380 --> 00:20:46,980
‫Perfect.

295
00:20:47,340 --> 00:20:48,970
‫All right, so it took quite a bit.

296
00:20:48,990 --> 00:20:55,620
‫As you can see, I already killed 40 oranges before I got one bomb, which means there's 10%.

297
00:20:55,620 --> 00:20:56,970
‫Well, it's 10%.

298
00:20:56,970 --> 00:20:58,470
‫It could happen any time.

299
00:20:58,470 --> 00:21:06,600
‫And it only happened after almost 40 or maybe even even 50, I think even 50 oranges, because I didn't

300
00:21:06,600 --> 00:21:08,100
‫hit every single one of them.

301
00:21:08,610 --> 00:21:09,120
‫All right.

302
00:21:09,120 --> 00:21:16,470
‫So I'd say let's go to the next video where we will see how to get the game over and to restart into

303
00:21:16,470 --> 00:21:16,980
‫our game.

304
00:21:16,980 --> 00:21:17,910
‫So see you there.
