Your example proj cleared things up completely! I just ran into one problem, the example didn’t work for 3D layers. It kind of shifted everything and I tried moving the anchor points but it only messed it up more. So I just pre-comp’d it and then made that comp a 3D layer. So that worked out great. Thanks so much for figuring this out for me! I’m really amazed by scripting. How did you learn to do expressions? I tried some tutorials but I’m just lost.
oh ok I get it. When I move the “Gear” null it does work. I guess the expression is linked to the position of the Gear Null? Right now, I have the “Gear Null” parented to the rotation of the Gear itself which is spinning on the z axis with “time*-60” Is there a way to make your expression work if the Gear Null is parented to something or do I have to animate the position by hand? Thanks.
David thanks for your rapid response. I tried this and as soon as I put your expression into the Z rot of my bar, it immediately rotated to the Hole null however as the gear turns with the bar attached, it no longer auto orients to the hole.
Hmm, my question was more in regard to each individual letters blinking on and off randomly till they are all lit. I was wondering if there was an AE text animation preset that does that? Thanks.
One thing I tried that kind of worked was making the Collision Shape “Moving Mesh” It previews slower but If anyone can think of something else please let me know. Thanks.
Thanks. Eventually I found a great tutorial by 3D Kiwi from C4D cafe. He had a tutorial called Tut88 Wheel. He went through all the Xpresso commands and explained the reasoning for each. I wish I could find the link. Thanks for your help
This is something I’m trying to do now. Being that this post was originally 2009, the Roll It plug in no longer works with R13. Can you give me the method for xpresso to use with the align to spline position so it rotates the wheels?
