I believe what you are talking about is physics/dynamics and in theory can be coded, but really AE is not an easy product to achieve this.

Dan’s web site has collision script that would help:

Are you sure you need an expression for this?
It sounds like all you want to do is have a ramped rotation on a 3d object.
What you are getting is basic math yeh?
The decreasing ramp number of the equation overtaking the small increase in frame number. Essentially the ramp is going down to zero and at some point is going to return you to your start point of zero rotation.

seedRandom(index,true);
pos = random([-800,-500,-500],[800,500,500]);

x = pos[0]*thisComp.layer(“slider”).effect(“x depth”)(“Slider”);
y = pos[1]*thisComp.layer(“slider”).effect(“y depth”)(“Slider”);
z = pos[2]*thisComp.layer(“slider”).effect(“z depth”)(“Slider”);

[x,y,z]

Dan answered this this one a while back.
Control everything from sliders.

Thankyou Dan, this is great.
I now understand the thought process a bit better.
Cheers very much.
