expression for switching between compositions
hey guys
anyone know of or how to make an expression where you could use a slider control to bring up different compositions? for example having four precomposed compositions of a characters front, back, and two sides and using the slider control to cycle through them so the character would essentially turn around or having a check box control that would control blinking or a slider control that would cycle different mouths for lip syncing, if anyone has any ideas to get me in the right direction it’d be much appreciated

A simple way would be to put all the precomps in a master comp, add a slider control to a null (“Null 1”), and add this expression to the opacity of the precomps:
slider = Math.round(thisComp.layer(“Null 1”).effect(“Slider Control”)(“Slider”) );
if (slider == index) 100 else 0;Then each layer will be visible when its layer index matches the slider, invisible otherwise.

awesome it works, thanks alot for your help! got another one for you, is there a way to give the slider a range where it only goes to say 1-4 instead of the infinite number it goes to by default?

I too like that expression/solution.
To set the range of a slider, Right Click the blue number values of the slider and choose “Edit Value”, then you can set the min and Max to what you want.
The default is 0-100, then widest range possible is -1000000 to +1000000.
