Expression Help
Hi,
I’m using this expression:
thisComp.layer(“Main Hinge”).transform.position[2]
to rotate a gear based on x position of another layer.
It works, but I want to reverse the direction of the rotation
and gear it down. Would someone suggest code I could use to do
this?Thanks,
Eric

adding a minus to the beginning of the expression should do the trick:
-thisComp.layer(“Main Hinge”).transform.position[2]
or you could do:
value – thisComp.layer(“Main Hinge”).transform.position[2]
to give you a bit of control for the starting value of the rotation…

Thanks,Kevin
I just hit on this before I read your post:
((thisComp.layer(“Main Hinge”).transform.position[2])*-1)but a negative sign before the expression is nicer.
Thanks,
Eric
