Description copied from interface: E3DCollisionDetector

Interface to check the collision between sourceObject and triangle.

Specified by:

checkCollisionDetectableObjectTriangleCollision in interface E3DCollisionDetector

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.
