class geCollider : public csCollider

geCollider takes care of game specfic collision detection

Inheritance:

Public Methods
virtual int CollisionDetect(gePhysicalObject*& pOther): Collide cd with all objects in the sector.
virtual void Explode(): removes the bullet and replaces it by an explosion
virtual int FindFirstCollision(csVector3 MoveVector, float MaxMoveDistance, csVector3& Moved, gePhysicalObject*& pOther): Try to move the collider for a certain distance
geCollider(geWorld* pWorld, csPolygonSet *p): The transformation which decsribes the objects current position and orienatation
virtual void OnCollision(gePhysicalObject* pOther): Is called, if a contained object is having a collision with another object

Public
: Initialize CD data for all sectors in the world.
: Free any memory held by CD system.
: Create a player bounding box.
: The sector in which the being currently resides.

Private Methods
virtual int CollisionDetect(csTransform* pTransform, csSector* pSector, gePhysicalObject*& pOther): used internally be geCollider, to do the real work.
int FindSectors( csVector3 v, csVector3 d, csSector *s, csSector **sa ): Find all sector which are near enough to intersect with this being.

Documentation

geCollider takes care of game specfic collision detection. It will only handle a single Frame of a Sprite. If you need multiple Frames, you will need multiple Instances of geCollider

virtual void OnCollision(gePhysicalObject* pOther)

Is called, if a contained object is having a collision with another object

virtual void Explode()

removes the bullet and replaces it by an explosion

The sector in which the being currently resides.

geCollider(geWorld* pWorld, csPolygonSet *p)

The transformation which decsribes the objects current position and orienatation

Create a player bounding box.

Initialize CD data for all sectors in the world.

Free any memory held by CD system.

virtual int FindFirstCollision(csVector3 MoveVector, float MaxMoveDistance, csVector3& Moved, gePhysicalObject*& pOther)

Try to move the collider for a certain distance. Will move the collider only in steps less or equal to MaxMoveDistance. When the collision is found, the Collider will be moved with a binary search to the last Position, that has no collision (The binary search will use 10 interation, which means, that the accuracy of position afterwards will be better than 0.001*MaxMoveDistance) Par: MoveVector: gives the amount of distance to move the collider. MaxMoveDistance: Maximum Distance to move in one step should be significantly smaller than the size of the object, to avoid missing some collision. Moved: The Distance that was really moved. pOther: returns a pointer to the involved collision partner, if it has some game object attached to it. returns: 0 if ther was no collision, nonzero, if there was one.
