Hello, in this video tutorial we are going to include a countdown so you have a limited time to cross the maze.

2
00:00:11,000 --> 00:00:27,000
We are going to use a countdown, we have to use a variable so we can store the time that is going by.

3
00:00:27,000 --> 00:00:40,000
So we will create a variable, by making a variable I am going to call it timeLeft

4
00:00:41,000 --> 00:00:59,000
and I will set an initial value at the beginning so I am going to give myself a timeLeft of let's say 1 minute

5
00:01:00,000 --> 00:01:05,000
so I am going to use 60 because I am going to count in seconds, right?

6
00:01:05,000 --> 00:01:07,000
Ok?

7
00:01:08,000 --> 00:01:16,000
Now, how do I count in seconds? The simplest way would be to use a wait.

8
00:01:17,000 --> 00:01:24,000
Under something there is also a timer here, see if you put a timer it starts counting from the beginning

9
00:01:25,000 --> 00:01:32,000
but it is simpler if you just use the control block wait one second.

10
00:01:32,000 --> 00:01:44,000
So, what I can do is any time a second goes by I will decrease the value of timeLeft by 1

11
00:01:45,000 --> 00:01:59,000
so I go into variables and change my variable timeLeft by minus 1

12
00:01:59,000 --> 00:02:13,000
and that has to go on forever since the beginning

13
00:02:14,000 --> 00:02:25,000
Well, I am going to remove the timer from there by going to sensing and remove the tick here

14
00:02:34,000 --> 00:02:38,000
I have to stop it for this to work

15
00:02:39,000 --> 00:02:47,000
Now, there it goes. My mouse is not working so well.

16
00:02:48,000 --> 00:02:55,000
Now, I want to have the timeLeft on the screen so under variables I do have the timeLeft tick

17
00:02:56,000 --> 00:03:03,000
See? I tick it so I can watch the timeLeft. I can place this somewhere else too

18
00:03:04,000 --> 00:03:10,000
Right there or here. Now.

19
00:03:11,000 --> 00:03:22,000
Well, let's say now when I start the time starts at 60 and becomes counting down

20
00:03:23,000 --> 00:03:29,000
So, what I want to know is if I have run out of time or not

21
00:03:30,000 --> 00:03:34,000
So, I have to ask with an if

22
00:03:35,000 --> 00:03:39,000
So, I say if

23
00:03:40,000 --> 00:03:52,000
and now I ask if it has gone all the way to 0 with an equal here

24
00:03:53,000 --> 00:03:59,000
and what goes to 0 is the timeLeft

25
00:04:00,000 --> 00:04:06,000
and I place here what I want to happen when I run out of time

26
00:04:07,000 --> 00:04:18,000
You can make a block here like dine or you can include a new variable for lives and subtract one life

27
00:04:19,000 --> 00:04:27,000
or you can just make it go back to the initial position like this

28
00:04:28,000 --> 00:04:30,000
wherever you want

29
00:04:31,000 --> 00:04:38,000
So, that's the way you include a countdown

30
00:04:39,000 --> 00:04:43,000
so you have unlimited time to cross the maze

31
00:04:44,000 --> 00:04:45,000
Thank you
