Working a treat. I’ve also tried just adding the difference in the X dimension at start point to .position and that works.
Now I see I’ve created a problem. My pusher man stretches back before then moving forward and the wheel is tied to him so also flies backwards. Not a good look!
I can’t find any material on how to only introduce the linked expression after a point in time (or a keyframe)…I’m guessing unless there’s a keyframe option, it’s an if clause of some kind…aaarrgghh…the things you do to learn this stuff!
Tks!!!
