Link position value to frame number
Hello helpful folks!
I’m trying to make a chin on a character move to certain mouths on a time remapped layer.
How would I start this?
I want to have 3 different frames from a time remapped layer move the position of a chin layer slightly down then the other frames move it back up to the original position.Im guessing I would put the expression on the position of the chin layer, telling it to move when the remapped mouth layer hits certain frames. Ie. be in position x at frames 2, 4, 6 and be at position y at frames 1, 3, 5.
Any help is always much appreciated. Thanks!

Here’s what I’ve gotten so far….
I put this on the position of my chin layer:
A = framesToTime(thisComp.layer(“Mouths.mov”).timeRemap);
B = [377.5, 606.0]; // chin down
C = [377.5, 597.0]; // chin upif (A == 7){B;} else{C;}

The timeRemap value is going to be in seconds, so I think you’ll need to use timeToFrames() instead.

That worked but say I want more than just one frame to move the position, would I add an array? Or is there some way of bracketing that says if the value is one of these numbers then B?
A = timeToFrames(thisComp.layer(“Mouths.mov”).timeRemap);
B = [377.5, 606.0]; //chin down
C = [377.5, 597.0]; //chin up
D = [2,3,6,9}; //frames to move chin downif (A == D){B;}else{C;}
Thanks so much for your help.

This would be one way (not tested):
A = timeToFrames(thisComp.layer("Mouths.mov").timeRemap);
B = [377.5, 606.0]; //chin down
C = [377.5, 597.0]; //chin up
D = [2,3,6,9]; //frames to move chin downval = C;
for (i = 0; i < D.length; i++){
if (A == D[i]){
val = B;
break;
}
}
val

It works, you are the man!
Does that mean your turning the values in D to 0 and if it’s not 0 then use C?
I’m just trying to understand it. Thanks for your patience.

No, the last part assumes the result (val) will be C, but then it loops through array D, looking for a match. If it finds one, it uses B instead.
