This version offers 4 intervals: 40, 30, 20 and 10 seconds. Each interval is triggered here by a key press: 4 for 40 seconds, etc. You could use lots of ways to start the timer in a project. You could also use various ways of hiding the presence of the timer on the screen. ____ The Timer sprite moves 10 steps per second, but you could also change that to extend the amount of time the timer can track. ____ So this is a "module" not a full project. But it's interesting to watch the timer's track, and hear the ticking as the clock runs out... --Larry828
