Creating a countdown timer

I've got the following for a countdown/timer...

-----

Global number Timer = 5

System > On start of layout > TimerText > Set text to "time: " & Timer

System > Every 1.0 seconds > System > Subtract 1 from Timer

|--> System > Timer = 0 > System > Reset global variables to default

-----

...but the countdown doesn't start - it just sits there at 5. Any ideas?

The structure could be wrong such that reset global variables is happening constantly. You could have other events affecting it, if there are any. Post a screenshot of the events.

Here's the top of the event sheet...

Oh right. The variable will be changing but your text isn't updating. You only update it once on start of layout when it is 5. You have to use set text whenever you expect the variable to change, although the manual advises trying not to use every tick on a bunch of text objects if you can avoid it.

Sorted it

Actually, not quite sorted.

Is it possible to show a countdown to 2 decimal places?

ie rather than 3 seconds to go, it displays 3.00 and the incrementals between?

System>every tick> set text

And every 0.01 sec > subtract 0.01
