Ghost AI

The ghosts has 3 behaviors : hunting, fleeing and scatter. When a ghost spawns it enters scatter mode.

• Scatter: It goes to a specific corner of the level. When the ghost has reached its destination it switches to hunting mode.
• Hunting: All the ghosts have different behaviors here.
  • Blinky: Samples pacmans position and heads towards it.
  • Pinky: Samples the intersection pacman is looking at and pathfinds to it, constructing a path around pacman. If Pinky is located at the intersection when sampling, she heads towards pacman.
  • Inky: Switches between the other ghosts behaviors at random.
  • Clyde: Walks around randomly.
• When pacman eats a pill the ghosts turn blue, and when the blue animation is over they switch to scatter mode.

When a ghost has sampled a target for pathfinding, it does not update it again until it has reached its target.
