hello, i've been having some problems with RPG movement. i've been copying the RPG example's character physics from the help page and modifying it to make my own RPG. my only problem is that movement is very flawed. i've changed the character and game's physics to make it identical to the example, but all of the alterations had the same effect. when i try to move in various directions at the same time, sometimes the character gets stuck and can only move in a "line" (no left and right or up and down) until you let go of the keys. i haven't seen this anywhere else, and in every RPG flowlab game i've played the movement is perfectly fine. what could it be? and if this helps in some way, i'm trying to make an EarthBound styled RPG. thank you!
