brunopalermo Yes, but it doesn't do rotation, and I notice the white square continues to move when the platform changes direction. While that seems to imitate real life inertia, it isn't actually scripted to do that (as far as I can tell) and is therefore an undesirable side effect (due to lag, maybe?).
To make matters worse: In my game the ship has walls which have solid behavior, and the ship is controlled through custom movement behavior. The player is currently controlled through 8 direction behavior (while I experiment). I got the player to move around on the ship and stay with the ship by applying the same angle and acceleration to the player as I do to the ship. This works pretty good, but all the walls solid behavior lags behind the graphics of the walls while the ship is moving. So even though you see a wall where it's supposed to be, it won't stop you from moving until you are further aft of it (the exact difference depends on how fast the ship is moving).
