How to keep a value in a if/else condition

[Declan Smith]

Just put value there as below

if (transform.position[2] > -1) {
value
} else {
text.animator("Animator 1").selector("Range Selector 1").offset
};

Thanks, I ve try and it goes back to zero, and I want it to keep the last known values. so… if its true continue your path else keep your value at this time.

Thanks, Ove try this and when the condition is not meet, it return to zero. I want it to keep the last know value.

This is one of those things that seems like it should be simple, but really isn’t. It’s because an expression has no access to values it calculated in the past. What you need is a threshold detector–a piece of code that goes back in time, frame-by-frame, looking for the most recent frame where the layer’s z position went from being less than -1 to being greater than -1. Try this:


threshold = -1;
trig = false;
for (f = timeToFrames(time); f >= timeToFrames(inPoint); f--){
tCur = framesToTime(f);
v = transform.position.valueAtTime(tCur)[2];
if (trig && (v < threshold)) break;
if (v >= threshold) trig = true;
}
t = (trig) ? framesToTime(f+1) : time;
valueAtTime(t)

Thanks for the help, it doesnt work. It go back to zero. I want the offset value of my text layer to stodd still when the Z position is close to zero. Im sending my project file if you want to have a look at it.

Ah, OK. Change the last line to this:

text.animator(“Animator 1”).selector(“Range Selector 1”).offset.valueAtTime(t)
