Control Scale with a Null

[Simon Terrey]

Hi there! I used to use this expression to control an objects scale with a Null but it no longer works in CC2023:

AE says: Line 7 (dis = length…) is at fault. Has the expression language changed?

mouse_layer = thisComp.layer(“Scale_Control”);//Mouse layer

beginScale = [100,100]; //

endScale = [50,50]; //

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, endScale, beginScale);

Try changing this line:

dis = length(this.position, mouse_layer.position);

to this:

dis = length(position, mouse_layer.position);

Amazing! When I turned ‘Legacy ExtendScript’ on in Expressions in Project Settings the old script worked but yours works fine in JavaScript.

Thank you so much Dan!
