Climbing a moving object?

I’ve got a half decent climbing system working, currently.

Essentially, I set the movement mode to flying, orient the player parallel to the surface they’re trying to climb, and only allow movement in that plane.

But, ultimately, I want to have the player climb moving objects, and I suspect this method won’t work. How can I constrain the player to a specific point on an object, even if that object is moving?

This sounds like a great answer… but it’s way over my head. I appreciate the assist, though.

Have you tried ‘attach actor to actor’?
