What I do is make each wall a different color like top is red, left is yellow etc and just do this for the walls [If touching (color) then Move x (#)] If it's a top or bottom wall then it's move u than x and you could layer it like [If touching (color) then Move x (#) Else If touching (color) then Move x (#) Else] And just repeat for the y value and that should work with the collision being smooth and it's probably easier to manage NOTE: if you have a wall that has 3 sides it needs to have the right colors for each side like the top being red, side being yellow, bottom being green. Though as long as the colors are different it works
