I have a game. The camera is located at a bird's eye view point, therefore, all characters are visible only from the top. I am having this problem, I do not know how to alter their baseline and blocking range in way that will allow them to move around regularly, but not stand on top of one another all the time as they do at present.
Are there multiple characters playable, or can you get away with not drawing walkable areas under where you are putting the NPC's?
No, there are about four playable characters. Sorry, any other solutions?
