Bit Description for SetCollision

const TOPHIT = 1; |
This bit descriptor is used by the GEL boundry hit routines. When the user's boundry-hit routine is called (via the argument set by a call to SetCollision) the first argument passed to the user's routine is the Pointer of the GEL involved in the boundry-hit, and the second argument has the appropriate bit(s) set to describe which boundry was surpassed.
