Hi guys,

I’m working on a game, and I’m a bit stuck on something that I think I’m really close to solving.

I have an actor, which I can move around on a platform (Top-down view)

The platform rotates, and I want the actor to receive the x- and y acceleration, so that it appears to be on top of the platform, and thus rotate together with it. I don’t want the actor to rotate ‘inside’ the platform, because of some other constraints 🙂

I hope this is a bit clear…
