Grab x,y,z and hold

[Dan Ebberts]

This should do it:

thisComp.layer(“other layer”).transform.position.valueAtTime(0)

OK, this seems to work, add the expression to the Slave’s position:

thisComp.layer(“Master Layer”).position.valueAtTime(thisComp.layer(“Master Layer”).inPoint)

It will take on the “Master Layer”‘s initial position, it’s inpoint position really, no matter how the two layers fall in the timeline. Obviously you can rename the “Master Layer” to whatever your layer name is.

This expression can probably be shortened up, I’m just a hacker, kind like Dr Frankenstein taking bit’s and pieces from other’s expressions.

Ooops, didn’t see you Dan, it took me awhile to work that one out.

Dan, can my inPoint version be shortened?

Thanks Dan, but i’ve noticed an oversight on my part. I’m trying to grab the x,y,z (which is under the position field) from a point light and apply it to my particular emitter. The problem is that in particular the x,y are on one field and z is on another (“position XY” and “position Z” respectively). So i tried pick-whipping from “position Z” to the just the z value of my light and added in “valueAtTime(0)” to look like this…

thisComp.layer(“particle follow”).transform.position.valueAtTime(0)

But i get an error “expression result must be of dimension 1, not 3”.

Any thoughts?

The only thing I can think of would be to do it this way:

L = thisComp.layer(“Master Layer”);
L.position.valueAtTime(L.inPoint)

Try it this way:

thisComp.layer(“particle follow”).transform.position.valueAtTime(0)[2]

Works like a charm. Thanks Dan!
