Umm...I'm not sure what you're doing but aren't these equivalent:

name.move -r x y z;

vs.

name.translateX += x;
name.translateY += y;
name.translateZ += z;

Sorry if I'm just confusing you. I still haven't woken up completely

I'm not even sure if you can write "+=" but practically this is the same:

name.translateX = name.translateX + x;
name.translateY = name.translateY + y;
name.translateZ = name.translateZ + z;
