dim |

The length of one side of a hash cell. Default is 100 count |

count |
in number |
The number of cells in the hash table. Default is 1000 |

The spatial hash
of active Shapes can be tuned to
improve collision detection. dim establishes
the size of a hash cell
(default 100), and count sets the number of hash cells (default 1000).
dim should approximate the side length of a typical Shape. A good rule of
thumb is to set count to about ten times the number of Shapesin the space.
