Couple more expressions questions, I sure could use help solving this one.


I'm trying to animate "direction" from an lighting effect and add this
"direction" animation to another layers position but the expression keeps
breaking.

Imagine a lighting bolt from your hand, shooting out and locking to a
moving target.  I've got the target track position, but I can't seem to
write the expression correctly to add the target position AND add my hand
key animation together.

I've just tried to use a simple "+" but that's not working.

effect("Advanced Lightning")("Direction") + thisComp.layer("TRACK
6").transform.position


Lastly,  how would one write the expression so I could access a world
position from a layer?

for example, I have a layer with a still using puppet tool I want the
connect too.  but this still is also parented to another layer for a track.

effect("Advanced Lightning")("Origin") +
thisComp.layer("ELEMENT.png").effect("Puppet").arap.mesh("Mesh
1").deform("Puppet Pin 2").position

Thanks,
John
