I found this expression posted by Colin Braley, and I need some help to modify it.
Its about making an effect similar to Apple doc that magnify the icons when the mouse cursor come close.

//Begin expression
mouse_layer = thisComp.layer("mouse layer");//Mouse layer
beginScale = 100;//Scale begins at this
endScale = 250;//Scale ends at this
beginDistance = 200;//Distance to begin magnifying in pixels
endDistance = 0;//Distance to end magnifying in pixels
//--Don't modify below here
dis = length(this.position, mouse_layer.position);
ease(dis, beginDistance, endDistance, beginScale, endScale)

//end expression

What I want to ask, is it possible that instead of scaling the layers, they move forward and backward toward the camera in z-axis when the mouse layer get close to them?

Thanks in advance.

Post this in the After Effects Expressions forum. Dan Ebberts checks in there a lot and he REALLY knows this stuff.

I can't even get the expression to work as is..
But in theory my theory at least, this should work:

//--Do modify below here
dis = length(this.position, mouse_layer.position);
z=ease(dis, beginDistance, endDistance, beginScale, endScale);


But as I can't get the expression to work, I cant confirm it. Dan Ebberts is the man I want to be, hence why i tried to have a look at it.. to no avail.
