Stop expressions expression?

[David Conklin]

As far as I am aware, you cannot access the time of another comp – only the time in the comp in which the expression is written. However, if you make a new null inside your master, call it ‘timecount’, place a slider on it, name the slider ‘timecount’ and add this expression onto that slider

time;

You now have a marker of the current time in your master comp.

Now, you just need to wrap all of your expressions inside your precomp in an if-else statement. There are lots of nice tools to do this, pt_ExpressEdit is one of my favorites. You can do it manually, of course, if you don’t have too many.


var theTime = comp("masterComp").layer("timecount").effect("timecount")("Slider");
var timeToStopExp = 10; //seconds
if(time < timeToStopExp){
//place your expression here.
] else {
//the disabled value here:
value;
}


Change the timeToStopExp variable to whatever second you want your expressions to be turned off.

Good luck!
