I'm currently building a small plat former for my A-Level project and have ran into an issue that I or my friends cant solve. The player seems to glide a lot to the right and not to the left (note: the small glide on the left is whats needed) and platforms seem to not move correctly either, some do as needed like the walls but then floors don't and everything clips to the right side of the screen. Any suggestions would be helpful.
