Hy guys
Thanks for the reply.
I intend to restrict a player movement only, forcing that he can only move along a narrow path (like a rail or track) with multiple branches (like a maze). This way, he can go back and forth from any direction, including diagonally if necessary. A simple example attached
Thanks
