just wasd to move the character
it's a new way to collide to the wall, insteed of just moving the opposite way of the wall you walk in too you will set your position to were you last where before you touched the wall. this will prevent clipping in to the wall and be able to get to the other side. the only disadvantage with this that i could see is that you can't slide against the wall so it feels like you stick to it. this is best for clones if you whant them to be able to collide with the wall and go towards the player at the same time.
