ok, to start off i did not have any part in making this and i dont know who made it! and it's not really a script but can still be used!!!
i saw on a few sites people saying you can't really make platform games and if you do the only ones online are laggy and not very good.
BUT, i found this on a site when i was bored. have you ever played METROID or SUPER METROID? well this file is exactly what you need if you want to create a game like them. i played it for a bit and it didnt seem to have any problems (except when you go on the moving platform you have to move with it, it doesnt move you)
hope this helps anyone planning on making a platform game!!!!
(if i cant do this, let me know and ill remove the file)
