For a game, if you're using the PMO for the character movement and using flags and +1/-1 Moving platforms, how do you keep the player on? And also the same for up and down platforms.
I got around this by using a detector and an extension-free physics-y engine for the platforms. Say they move 1px in any direction - the players X and Y positions are set to 10x that (since the PMO can deal with some very small numbers).
