*** How To Write a Pacman Game in JavaScript ***

“The game described here differs from the original “Pac-Man”™ by Namco™ <http://www.namco.com/> in some ways:

The original game uses only one layout populated by four ghosts, each ghost guided by a distinguished strategy and moving at its own speed. The various levels differ by the ghosts’ strategy and the speed of the game. Opposed to this, the game as described here will be populated by ghosts employing a shared set of movement strategies. (The speed will probably be the same as the speed of the pacman character or a fraction of it.) In order to entertain some difference to the game play each level will have its unique layout. This conforms with the typical appearance of a Pac-Man clone.

The original “Pac-Man” by Namco and its clones share the following features – as does the game described here: The player guides a little yellow ball (the pacman) through a maze-like labyrinth in order to clear all the food (embodied by tiny white dots) laid out in the passages of the labyrinth. His opponents are 4 ghosts of different color roaming the labyrinth in search for the pacman. If any of the ghosts comes in touch with the pacman, the pacman looses a life and is reset to its original position. Some of the food dots (usually four of them) are bit bigger and provide a reversed game play, when eaten by the pacman: For a limited amount of time the pacman now may haunt and eat the ghosts. (This phase is indicated by the ghosts’ color – usually a deep blue.) If the pacman manages to get grip of a ghost in this special phase, the ghost is not killed, but set to the central cage, from which it emerged at the beginning of the level.
