public interface E3DCollisionDetector

Author:

espresso3d The base interface from which to derive a custom collisiondetector. A collision detector is a class that actually determines if two bodies collide and, if they do, returns an E3DCollision object containing the collision information. Several collision detectors are already implemented and available from the engine's collisionDetect object.

Interface to check the collision between sourceObject and triangle.

Parameters:

sourceObject - The object that is moving that we are looking for collisions from

startPos - SourceObject's starting position

endPos - SourceObject's ending position

world - The world this collision is being checked for in

sector - The sector this collision is being checked for in

triangle - The actual triangle we are checking for collision into by sourceObject

possibleCollisionObject - The object that the triangle is from that we are checking if source object will run into

Returns:

An E3DCollision object containing collision information if a collision occurs, or null otherwise.

Interface to check the collision between sourceObject and a boundingObject

Parameters:

sourceObject - The object that is moving that we are looking for collisions from

startPos - SourceObject's starting position

endPos - SourceObject's ending position

world - The world this collision is being checked for in

sector - The sector this collision is being checked for in

boundingObject - The actual boundingObject that we are checking to see if sourceObject runs into

possibleCollisionObject - The object that the boundingObject is from that we are checking if source object will run into

Returns:

An E3DCollision object containing collision information if a collision occurs, or null otherwise.
