Pac-Man Ghost Behavior-Analysis
Schönes neues Blog namens GameInternals, das erste Posting ist eine lange, ausführliche Analyse der Bewegungen von Blinky, Pinky, Inky und Clyde.
The ghosts are always in one of three possible modes: Chase, Scatter, or Frightened. The “normal” mode with the ghosts pursuing Pac-Man is Chase, and this is the one that they spend most of their time in. While in Chase mode, all of the ghosts use Pac-Man’s position as a factor in selecting their target tile, though it is more significant to some ghosts than others. In Scatter mode, each ghost has a fixed target tile, each of which is located just outside a different corner of the maze. This causes the four ghosts to disperse to the corners whenever they are in this mode. Frightened mode is unique because the ghosts do not have a specific target tile while in this mode. Instead, they pseudorandomly decide which turns to make at every intersection. A ghost in Frightened mode also turns dark blue, moves much more slowly and can be eaten by Pac-Man. However, the duration of Frightened mode is shortened as the player progresses through the levels, and is completely eliminated from level 19 onwards.
