Horizontal Flipping Help needed…
Hi there, I’ve never really used much expressions before so apologies for my ignorance, but I’m after something that can create this:
I’d like an expression that can use the scale/position properties of an animated layer and do the exact opposite / a horizontal flip…
On the left side of the screen I have a layer starting out big and getting smaller and coming in to the center of the screen, this is being used as a parent and then other layers attached, and I need the exact same motion happening symmetrically on the right side to parent my new right hand layers
I’ve done this for the scale property so far:
thisComp.layer(“3”).transform.scale*-1
This has flipped the layer but vertically also, I only want the width effected, I’ve tried adding the (0) property after scale so that it only effects this but it didn’t work…
Any help would be much appreciated!!
Thanks,
Steve -

Hi Steve,
this is the correct syntax:
for scale (2D):
s=thisComp.layer("3").transform.scale;
[-s[0],s[1]];
for scale (3D):
s=thisComp.layer("3").transform.scale;
[-s[0],s[1],s[2]];
for position (2D):
p=thisComp.layer("3").transform.position;
[comp.width - p[0],p[1]]];
for position (3D):
p=thisComp.layer("3").transform.position;
[comp.width - p[0],p[1],p[2]];

Hey Filip, thanks for your response!
The scale has worked perfect thanks, but I get an AE warning when entering the 2d position property: Class ‘Function’ has no property or method named ‘width’
p=thisComp.layer(“3”).transform.position;
[comp.width – p[0],p[1]];Any suggestions?
I have actually got it all working now, but that’s been by doing math – copying all the keyframe information, finding the difference between them and applying that to the flipped layer once first frame is in exact position
Thanks again,

Oops,
that should have been:
p=thisComp.layer(“3”).transform.position;
[thisComp.width – p[0],p[1]]; -
Thanks Filip, that’s worked spot on!
Steve
