1
00:00:01,150 --> 00:00:04,880
Okay, so we're got our say method,
but let's go ahead and

2
00:00:04,880 --> 00:00:07,910
have our monster be able
to do a few more things.

3
00:00:07,910 --> 00:00:12,300
And we're gonna store these things and
count them and

4
00:00:12,300 --> 00:00:15,820
put a scoreboard on our monster later.

5
00:00:15,820 --> 00:00:19,960
So, we're just gonna say that
our monster has some actions and

6
00:00:19,960 --> 00:00:21,460
when we initialize our monster,

7
00:00:21,460 --> 00:00:26,190
we're gonna keep track of these in
an instance variable called actions.

8
00:00:27,280 --> 00:00:32,760
And we'll say that our monster,
first off, can scream.

9
00:00:32,760 --> 00:00:34,050
Isn't that scary?

10
00:00:35,350 --> 00:00:41,080
And let's go ahead and make the actions
an attribute reader as well.

11
00:00:43,540 --> 00:00:49,660
So now let's go ahead and define a scream
method, and it's going to take a block.

12
00:00:52,230 --> 00:00:58,287
And we will yield to the block so
that the block gets called,

13
00:00:58,287 --> 00:01:03,011
and let's go ahead and
just print to the screen

14
00:01:03,011 --> 00:01:08,852
name, And screams.

15
00:01:10,665 --> 00:01:13,310
This method is almost done.

16
00:01:13,310 --> 00:01:17,460
First thing that we want to do,
is increment

17
00:01:18,960 --> 00:01:23,770
the number of screams that
our monster has done.

18
00:01:25,960 --> 00:01:28,040
So now let's go ahead and call this block,

19
00:01:32,691 --> 00:01:36,324
With our fresh new method, and

20
00:01:36,324 --> 00:01:42,170
we'll just go ahead and
print BOO to the screen.

21
00:01:42,170 --> 00:01:44,160
That is pretty scary.

22
00:01:45,250 --> 00:01:48,796
Now let's go ahead and
run this program, see what happens.

23
00:01:48,796 --> 00:01:52,290
Uh-oh, undefined method + for NilClass.

24
00:01:52,290 --> 00:01:54,250
Let's see what's going on here.

25
00:01:54,250 --> 00:01:57,714
That is on line 25.

26
00:01:59,840 --> 00:02:02,653
And, on line 17,

27
00:02:02,653 --> 00:02:07,620
undefined method + for NilClass.

28
00:02:08,890 --> 00:02:10,795
Let's see what's going on here.

29
00:02:10,795 --> 00:02:19,060
Oh, we had the wrong key
that we were referencing.

30
00:02:19,060 --> 00:02:21,780
So now that we fixed that,
let's run it again.

31
00:02:23,360 --> 00:02:26,150
Okay, Fluffy screams, BOO!

32
00:02:26,150 --> 00:02:29,690
Now let's go ahead and for
now, just put to the screen

33
00:02:31,660 --> 00:02:34,580
the action counts here and
see what happens.

34
00:02:36,870 --> 00:02:37,760
Okay, that makes sense.

35
00:02:37,760 --> 00:02:40,543
We have one scream, and
that's what we thought.

36
00:02:43,937 --> 00:02:45,989
And let's just print it
out beforehand too, so

37
00:02:45,989 --> 00:02:47,900
that we know that it's being incremented.

38
00:02:51,125 --> 00:02:56,437
But now when we call the scream method,
we know that the block is executed and

39
00:02:56,437 --> 00:03:00,590
the number of screams in our
internal hash is incremented.

40
00:03:02,590 --> 00:03:04,040
So, now that we know that that works,

41
00:03:04,040 --> 00:03:07,140
we can go ahead and
create another couple actions here.

42
00:03:08,950 --> 00:03:12,590
Let's go ahead and create one for
scares cuz that's what monsters do,

43
00:03:12,590 --> 00:03:14,040
they scare people.

44
00:03:16,030 --> 00:03:17,740
And, the scare method's
gonna be the same thing.

45
00:03:24,482 --> 00:03:29,199
We'll go ahead and
increment the number of scares.

46
00:03:29,199 --> 00:03:33,932
And then, We'll print

47
00:03:33,932 --> 00:03:37,970
that the monster has scared you and yield.

48
00:03:46,268 --> 00:03:48,340
So now we'll call it and
make sure that that works.

49
00:03:50,930 --> 00:03:54,660
And our monster will scare you by saying,
go away.

50
00:03:54,660 --> 00:03:57,455
That is pretty scary.

51
00:03:57,455 --> 00:04:00,080
So I'm going to clear my screen on
the console down here, and run this again.

52
00:04:01,120 --> 00:04:01,710
Okay.

53
00:04:01,710 --> 00:04:06,960
That works, and the screams went from
zero to one, and so did the scares.

54
00:04:08,140 --> 00:04:11,780
And everything is printed out
just like we expect it to.

55
00:04:15,599 --> 00:04:17,340
Let's make a couple more methods here.

56
00:04:18,670 --> 00:04:20,700
One for run and one for hide.

57
00:04:22,919 --> 00:04:27,733
And I'm just gonna paste these in
since they are pretty much exactly

58
00:04:27,733 --> 00:04:28,840
the same here.

59
00:04:30,000 --> 00:04:34,480
They are just like the scream and
scare method.

60
00:04:34,480 --> 00:04:38,245
We also have run and hide, because those
are two things that monsters can do.

61
00:04:43,066 --> 00:04:51,064
And now all we have to
do is say monster.run.

62
00:04:54,031 --> 00:04:59,000
Monster is gonna say a scary
thing when it runs and,

63
00:05:03,501 --> 00:05:07,230
Monster is also gonna say something very
scary when it's running away and hiding.

64
00:05:08,770 --> 00:05:12,130
Now let's run this real quickly and
see what happens.

65
00:05:12,130 --> 00:05:13,500
Uh-oh.

66
00:05:13,500 --> 00:05:18,890
It looks like undefined method + for
NilClass,

67
00:05:18,890 --> 00:05:24,020
because we forgot to add
these to the actions.

68
00:05:34,750 --> 00:05:37,977
Okay, let's go ahead and
run this one more time, and

69
00:05:37,977 --> 00:05:40,860
it looks like that works
just as we expect it to.
