I am trying to experiment with making walls/boundaries. So far I can make an object/wall that prevents the motion of the player, but I am having trouble making it so the monsters cannot pass through.
I have tried making the walls and monsters solids as well as played with the physics behavior. Also tried to have the monsters choose a new angle based on collision or overlap of the wall, but none have stopped them so far.
(This is based within the framework of the ghost shooter game so far, ie top down shooter)
