Time referencing
I’m wondering if anyone knows if it is possible to cite variable values from the past. Specifically, if the position of one layer is pick-whipped to the position of another layer (which is always changing), how could I say: position[0] + (position[0]’s value from one frame back’). Assuming position[0] is changing every frame. Thanks for your advice!

Hi David,
for properties of layers you can simply use valueAtTime(time),
so in your example:
position[0] + position.valueAtTime(time-thisComp.frameDuration)[0];

Hey thanks for that! Exactly what I needed.
One more thing, if I have linear movement from point 0,240 at second 0 and I want a motion path to travel to 720,y at second 10 where y is a random point between 0 and 480, how could I set that up?
