Rotation driving limited pingpong rotation
What I’m having trouble doing is this…
front wheel of bike “layer A’ rotates continuously
for every 360 degrees I need rider’s body “layer B” to rotate from -15 deg to -5 deg and then back to -15 deg. I know how to link the two properties but not how to limit and “pingpong” the “layer b”. Any and all help is greatly appreciated. -

Perhaps use a sine or cosine ? That will make a 0-360 value fluctuate between -1 and +1
It’s smooth by nature, but it might be just the ticket:
r=thisComp.layer("layer A").transform.rotation
pingpong=Math.cos(degreesToRadians(r));
linear(pingpong, -1, 1, -15, -5);

knew a sine or cosine would do it just didn’t have the language down. This works perfectly thanks a ton.
