public class PhysicsEngine

extends java.lang.Object

The Physics Engine. This takes care of calculating movement due to gravity or velocity in addition to taking care of World Collision Detection. Revision History: v1.7 (2004-04-13) - Added code for climbers, gliders, and floaters v1.6a (2004-04-13) - VLAD: I updated the ray-tracing code for the J direction, so that when the lemming or whatever hits the ground, the first component is not -1, but rather just the negative of the real value. The real value cannot be negative, so that's fine. That fixes the bug, where the lemming dies but doesn't really reach ground visually. v1.5a(2004-04-12) - Negative Gravity now works v1.5 (2004-04-12) - Rewrote most of Physics Engine, PMD should shut the hell up now. Added Particle calculations, fixed rayTracing when falling up, calculations now work for crazy Gravity settings up to around 11, above that and strange things happen. Velocities will work at any value, so long as gravity is not too wild a number. Currently, a negative gravity causes problems. v1.1 (2004-04-01) - Updated stuff so the lemmings' animation is handled correctly upon reversing direction.
