stopping an expression after period of time
Hi all,
I’m very new to expressions (and AE in general) and was wondering if there’s a way to stop an expression from acting after a certain amount of time.
I have a wiggle expression on the null object for a camera, and I want it to stop wiggling after thirty seconds or so, but am not sure how to do it. It seems the expression affects all keyframes after the one to which I think I assigned it. I figured it would be active from that keyframe to the next. All I want to do is make it stop. Please, make it stop!
Thanks a lot. Excellent site by the way, nice job everyone.

One way would be to tie the wiggle amplitude to a slider and keyframe the slider value from 5 to 0 where you want the wiggle to stop. That lets you ease out of the wiggle if you want to (otherwise you might get a glitch as the value jumps to its non-wiggled state). It would look like this:
slider = effect(“Slider Control”)(“Slider”);
wiggle(.1,slider)Dan

Thanks a lot for the swift reply. Much appreciated. If I could give you an e-muffin, I would, and an e-pat on the back too.
I noticed the glitch before after reading another thread that said to make an “if time>x then regain control” or something to that effect (not familiar with the syntax). The camera glitched like you said.
I’ll give this a whirl. Thanks again.
