Start / Stop / Restart

Now let's use triggers!

Whenever something happens (via a trigger with is pressing a button, killing a monster, whatever!), current time is saved and runs for a certain time until the next trigger activates to stop time counting.

In the Layout window, insert a button with

- the name "SSR"

- the Text property "Start/Stop/Restart" instead of "OK"

- instance variable called "checkit"

Then insert a new text with the name SSR_Timer_txt

In the Event sheet, add a global variable called "Timer_SSR".

What do we want to do:

1. When the button is clicked, the current time is saved in Timer_SSR

2. The checkit is set to 1, to tell Construct 2 that is has been pressed once

3. The text box will show a new time clock starting from 00:00 (by subtracting the reference time in Timer_SSR from the current time), only if checkit=1

4. When the button is clicked again, it'll set checkit to 0. The text box time won't continue counting.

5. If you press the button again, it'll start all over from 0 (because current time is saved in Timer_SSR!)

Later we'll see how to stop the time and continue counting the time without resetting.

So, let's add accordingly some events:

Condition: Button SSR -> On clicked

1st sub-event: Button SSR -> Compare instance variable -> checkit = 0

Actions: System -> Set Value -> Timer_SSR -> time

Button SSR -> Set value of checkit to 1

Add an else to the first sub-event and the additional condition

Button SSR -> Compare instance variable -> checkit = 1

Action: Button SSR -> Set value of checkit to 0

Good, now let's add in the Every tick-condition following sub-event:

Button SSR -> Compare instance variable -> checkit = 1

Action: SSR_Timer_txt -> Set text to zeropad(floor((time-Timer_SSR)/60% 60), 2) & ":" & zeropad(floor((time-Timer_SSR)%60), 2)

Run and test!

Click first: Timer starts counting from 0

Click again: Timer stops counting

Click a third time: Timer starts counting from 0 again
