00:00:00,660 --> 00:00:06,260
Come back again this lesson is going to be very important and yet very simple and this listen we're

2
00:00:06,270 --> 00:00:12,300
going to find the interactions that the user does with the time is now the beginning of this interaction

3
00:00:12,300 --> 00:00:16,260
which is what we'll be doing in this lesson is actually very very simple.

4
00:00:16,370 --> 00:00:22,860
But as the time passes and we add more functionalities to this game I will be changing stuff in dysfunction

5
00:00:22,860 --> 00:00:23,470
as well.

6
00:00:23,610 --> 00:00:28,680
So if the school had to and an index card I'm actually going to go ahead and make your file.

7
00:00:28,920 --> 00:00:35,130
I'm going to call it View Controller plus touches.

8
00:00:35,190 --> 00:00:41,390
And so you control the plus touches and that is the file that is going to take care of or touches and

9
00:00:41,390 --> 00:00:45,390
that function and subsequently the interactions with the tiles.

10
00:00:45,390 --> 00:00:47,180
I'm going to go ahead into that fine.

11
00:00:47,190 --> 00:00:50,670
Say I need to import the UI kit.

12
00:00:50,670 --> 00:00:57,670
This is an extension to your controller and within it I have only one function called touches.

13
00:00:57,690 --> 00:01:05,160
And now if you're not familiar with that and that this is a part of the UI kit that tackles any interaction

14
00:01:05,160 --> 00:01:11,100
that the user causes with the interface you could very well do that with a top gesture recognizer.

15
00:01:11,100 --> 00:01:16,530
I choose to use the touch isn't that because I think it gives me more control over what I want to do.

16
00:01:16,770 --> 00:01:18,370
So here are the things that I wanted.

17
00:01:18,420 --> 00:01:20,350
First of all I want to get my touch.

18
00:01:20,610 --> 00:01:26,730
I'm going to say Let my touch be touch as Dot first and that's going to be a touch.

19
00:01:26,880 --> 00:01:30,210
And my assumption is that there is only one touch landing.

20
00:01:30,210 --> 00:01:32,890
That's why I'm getting the very first one.

21
00:01:33,000 --> 00:01:35,220
If you want you can actually check for that.

22
00:01:35,220 --> 00:01:41,380
You can see if touches count was larger than one in return or do something like that.

23
00:01:41,460 --> 00:01:45,220
But for now I'm going to go ahead and say the next thing I want to do is this.

24
00:01:45,390 --> 00:01:46,670
And that's the part that they said.

25
00:01:46,680 --> 00:01:48,100
It's very simple in here.

26
00:01:48,240 --> 00:01:53,390
All I want to do is I want to print the internal number of any of my labels.

27
00:01:53,520 --> 00:01:54,470
So let's do it.

28
00:01:54,480 --> 00:01:59,510
I'm going to set you flat Let's call this one tap tight.

29
00:01:59,850 --> 00:02:08,190
If there is going to be my touch down to view and I'm going to get it as my label if I have tapped on

30
00:02:08,190 --> 00:02:13,430
something that is off the top of my label let me repeat that because that's very important.

31
00:02:13,620 --> 00:02:19,710
I have touched some and the interface is touch could be anywhere could be on the timer label it could

32
00:02:19,710 --> 00:02:27,150
be on the you won't label but I'm saying if it was of the type my label it means do this.

33
00:02:27,210 --> 00:02:34,200
Only if I have tab on one of these many times which is a very good way for checking the type of objects

34
00:02:34,200 --> 00:02:36,520
that you want to be able to interact with.

35
00:02:36,660 --> 00:02:40,710
So I'm saying if it was of the type label here is what they wanted to do.

36
00:02:40,710 --> 00:02:52,050
Just print and say let's say this title is number and then I'm going to say give me tap.

37
00:02:52,110 --> 00:03:00,130
Tyler Dodd internal numbers internal number and that's all I have to do to get that.

38
00:03:00,240 --> 00:03:04,720
You now excludes giving me a warning saying internal number is an optional value.

39
00:03:04,740 --> 00:03:07,750
So I'm actually going to say force on rapide.

40
00:03:07,790 --> 00:03:14,250
I know the value actually exists because I have defined the values for them when I was creating my tiles.

41
00:03:14,520 --> 00:03:20,280
Now before I run the test of the app I have to show you something else I have to make sure that my tiles

42
00:03:20,280 --> 00:03:22,870
are actually user intractable.

43
00:03:23,050 --> 00:03:29,520
And we do that by going to all make tiles and in here I'm going to go ahead to that I make the tiles

44
00:03:29,880 --> 00:03:37,230
and I'm going to go ahead and say anywhere around here I'm going to say tile does use that interaction

45
00:03:37,430 --> 00:03:38,290
enabled.

46
00:03:38,310 --> 00:03:39,540
Is that true.

47
00:03:39,780 --> 00:03:45,360
So this you do it somebody in your make tiles to make sure that you're using interaction is enabled

48
00:03:45,630 --> 00:03:47,760
for each of these many times.

49
00:03:47,880 --> 00:03:50,430
Let's go ahead and run the app and if it all goes well.

50
00:03:50,550 --> 00:03:57,250
Now when we tap on any of the toys I should be able to see that internal number but anywhere else I

51
00:03:57,250 --> 00:03:58,710
shouldn't get anything.

52
00:03:58,890 --> 00:04:00,720
So let me clear my console.

53
00:04:00,780 --> 00:04:04,160
Now I said in town number is 3 1 6.

54
00:04:04,210 --> 00:04:05,550
When I type anywhere else.

55
00:04:05,550 --> 00:04:07,440
It doesn't actually do anything for me.

56
00:04:07,440 --> 00:04:14,190
It only does it when I tap on the tiles and that's all I had to do in this lesson and I had to make

57
00:04:14,190 --> 00:04:20,760
sure that my touches and that is successfully working only on the labels and our internal numbers are

58
00:04:20,760 --> 00:04:21,550
correct.

59
00:04:21,690 --> 00:04:24,090
With that in mind I'm going to move on to our next lesson.
