Change a layer’s position based on Slider
Hi all,
I hope you can help me, I only have a passing knowledge of expression and I’m struggling to make this work:
I have a character ready for animation, the torso is a time remap of instances so we get a full turnaround, said instances are controlled by a slider:
sliderPos = thisComp.layer(“B_CHEST”).effect(“BODY POSES”)(“Slider”);
framesToTime((Math.round(sliderPos)))So as to equate the time remap values to the slider (it’s an expression that I found that Dan Ebbert made)
Now, my struggle is in trying to re-position the top of the arm to match the change in the torso. I’d like to use specific x,y coordinates on the arm for each instance of the time remap.
Any help is greatly appreciated,
Best Regards -

I haven’t tested this, but it will probably be something like this:
sliderPos = thisComp.layer(“B_CHEST”).effect(“BODY POSES”)(“Slider”);
posArray = [[200,220],[210,220],[230,221],[235,220]];
idx = Math.min(Math.round(sliderPos),posArray.length-1);
posArray[idx]where posArray is your list of positions corresponding to each frame.

Whoops, Dan beat me to the punch. Anyway, this method works also, but probably isn’t as elegant of a solution.
sliderPos = Math.round(thisComp.layer("B_CHEST").effect("BODY POSES")("Slider"));
switch(sliderPos){
case 1:
[x,y];
break;
case 2:
[x,y];
break;
case 3:
[x,y];
break;
default:
value;
