If (true) set value for next 4 frames
Is it possible to make an expression that, when triggered, changes the value for a set amount of frames? For example:
if (statement == true) {
// set opacity to 100 for next 4 frames, then 0
} else {
0
}

Hi Jeremy. Expressions can’t modify values in other places than the property on which they are applied, for the current frame. But for your case there is a workaround. You can evaluate the statement for the previous 3 frames, and if it’s true, make opacity 100. I imagine your statement checks the value of a property in the project, so you can use .valueAtTime() .
Something like:
durationCheck = 4;
st = false;
for(i = 0; i<durationCheck; i++){
if( statement.valueAtTime(time-framesToTime(durationCheck)) == true ) st = true;
}
st == true ? 100 : 0;
