00:00:00,210 --> 00:00:03,810
Before we start, did you try solving the workbook yourself?

2
00:00:03,840 --> 00:00:09,600
If not, please click the link in the resources folder and follow the instructions for this workbook.

3
00:00:10,900 --> 00:00:13,600
Welcome to Workbook 5.11.

4
00:00:13,600 --> 00:00:18,340
Task one is to print a bunch of messages, so we'll start with that.

5
00:00:21,470 --> 00:00:22,430
System.

6
00:00:22,430 --> 00:00:23,630
Dot dot.

7
00:00:23,630 --> 00:00:25,790
Print line printing the following.

8
00:00:29,440 --> 00:00:31,870
And then there are four more things to print.

9
00:00:31,870 --> 00:00:36,100
So I'm just going to copy these inside of comments.

10
00:00:39,570 --> 00:00:42,310
Create for print line statements.

11
00:00:42,330 --> 00:00:44,340
Great to are the rules.

12
00:00:47,990 --> 00:00:50,660
If you rule a six, the game stops.

13
00:00:53,810 --> 00:00:56,930
And if they rule A for nothing happens.

14
00:01:00,880 --> 00:01:03,790
Otherwise you get one point.

15
00:01:07,930 --> 00:01:08,770
Splendid.

16
00:01:08,770 --> 00:01:13,690
And last thing to print, you must collect at least three points to win.

17
00:01:16,100 --> 00:01:20,510
And so this last part implies waiting for the user to submit something.

18
00:01:20,510 --> 00:01:25,070
So here we can just say scan next line, and that should suffice.

19
00:01:35,580 --> 00:01:36,040
All right.

20
00:01:36,060 --> 00:01:39,370
Task three is to make a wild loop that runs forever.

21
00:01:39,390 --> 00:01:44,010
Place your last scanned next line as the first line in the loop.

22
00:01:44,010 --> 00:01:45,840
And in the second line print.

23
00:01:45,840 --> 00:01:46,710
Hey, for now.

24
00:01:46,710 --> 00:01:47,910
Simple enough.

25
00:01:47,910 --> 00:01:52,470
So if you want to define an infinite wild loop, you just say, Well, true.

26
00:01:53,850 --> 00:01:57,240
A wild loop always runs so long as its condition is true.

27
00:01:57,240 --> 00:01:59,990
But if you put true, then it's going to run forever.

28
00:02:00,000 --> 00:02:04,970
So our instruction was to put this as the first line and then to print.

29
00:02:04,980 --> 00:02:05,700
Hey.

30
00:02:08,090 --> 00:02:11,420
Now we get errors here because this is now a dud code.

31
00:02:11,420 --> 00:02:17,840
It's unreachable code because the while loop runs forever without ever being stopped, which means this

32
00:02:17,840 --> 00:02:19,070
will never get reached.

33
00:02:19,070 --> 00:02:20,850
So let's comment it out for now.

34
00:02:20,870 --> 00:02:23,180
Place score of zero on top.

35
00:02:27,100 --> 00:02:27,480
Okay.

36
00:02:28,150 --> 00:02:30,610
In the interest of time, I'll press the run button.

37
00:02:32,020 --> 00:02:33,580
Keep pressing next.

38
00:02:34,120 --> 00:02:34,840
All right.

39
00:02:35,170 --> 00:02:37,500
Now it says remove the hate print.

40
00:02:37,510 --> 00:02:39,130
Will do just that.

41
00:02:39,730 --> 00:02:44,660
Define the roll dice function based on the following comment.

42
00:02:44,680 --> 00:02:49,120
We did something extremely similar to that in workbook 5.10.

43
00:02:50,360 --> 00:02:52,340
So you will say public static.

44
00:02:52,340 --> 00:02:54,170
It's going to return an integer.

45
00:02:56,480 --> 00:02:59,330
The function name will be called a roll dice.

46
00:03:00,430 --> 00:03:01,050
All right.

47
00:03:01,060 --> 00:03:08,890
First, your remember that math at random returns a decimal in the range of zero to less than one so

48
00:03:08,890 --> 00:03:14,180
it can return any decimal between 0 to 2.99999.

49
00:03:14,200 --> 00:03:18,250
And if you multiply it, whatever, decimal gets returned by six.

50
00:03:18,370 --> 00:03:23,560
If, let's say you got the minimum value, zero times six is still zero.

51
00:03:23,560 --> 00:03:31,060
But if math random were to return the maximum possible value of 0.99999, then that max value would

52
00:03:31,060 --> 00:03:34,920
become less than 65.999.

53
00:03:34,930 --> 00:03:43,840
So double random number can be any decimal within this range and whatever number we get, we're going

54
00:03:43,840 --> 00:03:45,670
to have to add one to it.

55
00:03:45,670 --> 00:03:50,170
Which means if this happened to be the minimum number now, it would be one.

56
00:03:50,200 --> 00:03:54,400
If it happened to be the maximum number that this piece of code can return.

57
00:03:54,430 --> 00:03:58,320
Now it's less than 76.999.

58
00:03:58,540 --> 00:04:04,300
And now if you were to typecast whatever random number ended up being at line number 28.

59
00:04:08,040 --> 00:04:10,200
One would still be one.

60
00:04:11,510 --> 00:04:18,680
But if this happened to be the maximum possible value of 6.999, it would just become six.

61
00:04:18,680 --> 00:04:24,980
Which means at this point we're returning a random number between one and six, which is pretty much

62
00:04:24,980 --> 00:04:25,860
a dice roll.

63
00:04:25,880 --> 00:04:26,540
All right.

64
00:04:26,540 --> 00:04:29,510
That would have been your hardest task, in my opinion.

65
00:04:29,510 --> 00:04:31,940
But we've done this countless times before.

66
00:04:32,360 --> 00:04:38,960
So task number five is during each run, call a roll dice and store the value in dice or roll.

67
00:04:39,380 --> 00:04:42,350
So here we've got a variable dice roll.

68
00:04:45,830 --> 00:04:48,140
We'll set that equal to roll dice.

69
00:04:48,260 --> 00:04:49,190
Simple enough.

70
00:04:49,190 --> 00:04:50,720
Did we have to print it?

71
00:04:52,200 --> 00:04:53,540
Uh, we sure did.

72
00:04:53,550 --> 00:04:54,470
We have to print.

73
00:04:54,480 --> 00:04:56,310
You rolled a dice roll.

74
00:05:05,290 --> 00:05:09,610
All right, In the interest of time, I'll just use the run button.

75
00:05:16,090 --> 00:05:17,710
And the loop runs forever.

76
00:05:17,710 --> 00:05:20,440
Every single time it runs, it prompts me to press.

77
00:05:20,440 --> 00:05:21,040
Enter.

78
00:05:21,040 --> 00:05:24,850
When I press enter, we're rolling a dice and then we're printing it.

79
00:05:24,880 --> 00:05:27,010
Nothing too crazy.

80
00:05:27,910 --> 00:05:29,740
Moving on to task number six.

81
00:05:29,740 --> 00:05:33,650
During each run, if they roll a six print end of game and stop it.

82
00:05:33,670 --> 00:05:36,470
So we would have to break the loop, quote unquote.

83
00:05:36,490 --> 00:05:40,060
If they were live four, then they would just continue with the loop.

84
00:05:40,090 --> 00:05:46,120
Otherwise, if they're all anything else, update the points variable by one and get them to keep rolling.

85
00:05:46,240 --> 00:05:47,620
So if.

86
00:05:48,280 --> 00:05:51,640
The dice roll is equal to six.

87
00:05:51,820 --> 00:05:53,620
We have to print.

88
00:05:54,350 --> 00:05:56,660
And of a game.

89
00:05:57,200 --> 00:05:58,700
And break the loop.

90
00:06:01,100 --> 00:06:04,910
Otherwise if the dice roll is equal to four.

91
00:06:06,000 --> 00:06:07,860
Then nothing happens.

92
00:06:10,470 --> 00:06:11,480
Zero points.

93
00:06:11,490 --> 00:06:12,690
Keep rolling.

94
00:06:16,320 --> 00:06:17,010
Else.

95
00:06:17,010 --> 00:06:23,580
If they roll anything that isn't six or four, then we can update the points variable by one.

96
00:06:24,790 --> 00:06:27,970
There is no points variable, but there is a score variable.

97
00:06:27,970 --> 00:06:29,200
So we'll say score.

98
00:06:30,690 --> 00:06:31,830
Plus plus.

99
00:06:33,720 --> 00:06:35,370
And then we're going to print.

100
00:06:36,400 --> 00:06:37,420
One point.

101
00:06:37,420 --> 00:06:38,470
Keep rolling.

102
00:06:47,480 --> 00:06:47,900
All right.

103
00:06:47,900 --> 00:06:54,410
And then after the game ends, So after it reaches this if statement and the while loop breaks, we

104
00:06:54,410 --> 00:06:59,900
need to check if their score ended up being greater than or equal to three, in which case they win.

105
00:06:59,900 --> 00:07:01,880
Otherwise they lose.

106
00:07:02,480 --> 00:07:04,160
So here we say if.

107
00:07:05,360 --> 00:07:09,590
Their score ended up being greater than or equal to three.

108
00:07:10,190 --> 00:07:12,800
Then we'll just say you win.

109
00:07:14,680 --> 00:07:17,110
Otherwise you lose.

110
00:07:22,210 --> 00:07:23,140
And that's all.

111
00:07:23,140 --> 00:07:26,270
We created a dice rolling game using wild loops.

112
00:07:26,290 --> 00:07:28,930
Before I forget, let me close scanner.

113
00:07:30,770 --> 00:07:31,340
And.

114
00:07:31,340 --> 00:07:37,580
All right, I'm not going to put a breakpoint here because for some reason, if you put next line right

115
00:07:37,580 --> 00:07:41,600
after your while loop, it makes it really hard to visualize the runtime.

116
00:07:41,600 --> 00:07:49,850
So I'm just going to put a breakpoint over here and one at the beginning of the if elseif else chain

117
00:07:49,850 --> 00:07:50,960
and we should be good.

118
00:07:57,500 --> 00:08:01,940
So now we're probably at line 17, which means we have to enter something.

119
00:08:02,450 --> 00:08:06,410
Dice roll is going to equal whatever roll dice returns.

120
00:08:07,550 --> 00:08:12,410
In this case, we've got a dice roll of one that does not equal six.

121
00:08:12,410 --> 00:08:14,210
That does not equal four.

122
00:08:15,680 --> 00:08:20,570
So our score increases by one because we rolled a good dice.

123
00:08:21,930 --> 00:08:23,250
And we start again.

124
00:08:28,470 --> 00:08:29,900
This time I roll a four.

125
00:08:29,910 --> 00:08:33,740
So fortunately for me, four means the game doesn't end.

126
00:08:33,750 --> 00:08:37,169
I'm still good, but I don't get a point on this turn.

127
00:08:38,820 --> 00:08:39,720
All right.

128
00:08:42,400 --> 00:08:48,830
This time I wrote a three that is just perfect, which means I get a point and I get to keep rolling.

129
00:08:48,850 --> 00:08:50,040
I think I'm going to win.

130
00:08:50,050 --> 00:08:51,400
Let's find out.

131
00:08:54,390 --> 00:08:55,260
I roll it, too.

132
00:08:55,290 --> 00:08:56,940
That is amazing.

133
00:08:58,580 --> 00:09:02,780
And get another point, which means I will eventually win.

134
00:09:03,770 --> 00:09:05,770
Next line, press submit.

135
00:09:05,780 --> 00:09:06,950
Roll the dice.

136
00:09:07,040 --> 00:09:07,860
Five.

137
00:09:07,880 --> 00:09:09,410
It is my lucky day.

138
00:09:09,410 --> 00:09:11,150
I have got four points.

139
00:09:13,220 --> 00:09:14,420
Press submit.

140
00:09:14,630 --> 00:09:16,990
This time I roll of four no points.

141
00:09:17,000 --> 00:09:22,100
I'm going to fast forward the video until I eventually roll a six because you're probably getting really

142
00:09:22,100 --> 00:09:23,360
bored of me right now.

143
00:09:24,080 --> 00:09:24,710
Never mind.

144
00:09:24,710 --> 00:09:31,130
I guess I won't have to fast forward because I did just roll with six, which means end of Game Break

145
00:09:31,130 --> 00:09:33,710
is going to break the entire while loop.

146
00:09:35,550 --> 00:09:41,490
And now that the loop has been broken, I ended up with a score of four, which is greater than or equal

147
00:09:41,490 --> 00:09:44,010
to three, which means I win.
