I've using the standard Platform controller to make a platform game and want to be able to 'knock back' a player if he touches a spike on the floor. In other words when the player collides with the spike object he will fly up and backwards a short distance. I'm trying to use the 'set platform' vector commands and setting the vector Y works fine (the player flies straight up) but setting the vector X doesn't seem to do anything no matter how large a value I use. Does anyone know why this isn't working or suggest a better way? Thanks!
