Yah, so I'm having trouble geting my ghosts to move in an orderly fashion. They are so chaotic and sometimes get stuck.That is the first code I will post. The other code is for my Pacman movement. I want him to only be able to change directions whenever he is sguare in an empty or dot tile. In other words when row%30 == 0 and column%30 == 0. I can't figure out where I can place this code so it will work.
Ok here is the Ghost code
