I want to put this into action script code: after exit frame
stop actionscript. I am creating a game and i put this flash file
before the game
http://ffiles.com/flash/actionscript/color_blend_rain_1366.html
but after i press the play button i still see the action script
taking effect and the blur bubbles take place through out the whole
game. Can someone please help me Thank You.
It would help so much if you can use an example.

Answer 1

And the first example he gave doesn't need to be stopped
because it will only do what it was called to do once.
The second one will repeat every 100 ms and can be stopped
whenever you want it to stop by doing:
clearInterval(f1Interval);
