Doc Effect
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.

Like this maybe:
mouse_layer = thisComp.layer(“mouse layer”);
beginZ = 0;
endZ = -500;
beginDistance = 200;
endDistance = 0;
dis = length(this.position, mouse_layer.position);
z = ease(dis, beginDistance, endDistance, endZ,beginZ );
value + [0,0,z]Dan

Thank for the reply, but it doesn’t work, maybe I missed some information, I attached the AE file so you guys can have a look at it.
Basically I want the layers (1,2,3,4) to move close & far toward the camera in z-axis once the (mouse layer) move close to them.The file:

You make have to tweak the parameters a little, like this:
mouse_layer = thisComp.layer(“mouse layer”);
beginZ = 0;
endZ = -1200;
beginDistance = 100;
endDistance = 0;
dis = length(this.position, mouse_layer.position);
z = ease(dis, beginDistance, endDistance, endZ,beginZ );
value + [0,0,z]But in any case, when the layer moves in z space, it’s not going to necessarily match up with the x position of your mouse any longer, because of the camera angle.

Perfect..
Its working very well.
Thanks you very much. -
Actually you are right about the camera angel, I was thinking of adding an x-position offset to the layer to move toward the center of the camera, is that possible? like
beginX = 0; endX = mouse_layer.position + something;
but how do you think it can happen?
mouse_layer = thisComp.layer("mouse layer");
beginZ = 0;
endZ = -1200;
beginDistance = 100;
endDistance = 0;
dis = length(this.position, mouse_layer.position);
z = ease(dis, beginDistance, endDistance, endZ,beginZ );
value + [0,0,z]
Thanks
