Say, how do you make your character in some sort in jrpg that it would not move when the player collides the wall as if for example, if they walk up to the wall, they wouldn’t go through.
Try that out and look is that what you need! 
I change player collision mask to be in center somewhere on the waist.

Do you mean you want to make your character be able to run up walls and across ceilings?
