Sorry, posted before I saw your reply. Thank you for the small corrections, but I already got most of that stuff handled. My problem is not the moving vector of the platform or detecting it, but correcting the player's position and pan if the platform pans. (in my case the 'platform' is actually a small spaceship)


Means: If the player is in the center of the platform, we would only have to adjust the player's pan (even that is a problem, because if I just add the angle the player starts to rotate uncontrollably, for some reason). But if he is further towards an edge, he has to be moved (rotated) around the platform's axis, so he will still stand at the same position. PLUS, his pan must be changed accordingly. And all that while he can still freely walk around the platform...
