Detailed Description

This defines Collision caching as well as the ability to sort into buckets.

This class is tasked with the following:

Handling and Caching collisoins
- Splitting objects into buckets
- Storing Collision lists

Todo:: change this to where you can specify collision from object poll perspective or by partitioning and listing collisions for all objects in a map.

bool Collision::collided	(	WorldObject *	a,
		WorldObject *	b
	)

inline

Lets us know if a collision had precviously occurred (order independent).

Parameters

b	second object

Returns: whether there was a previous collision

Here is the caller graph for this function:

bool Collision::collided ( pair< WorldObject *, WorldObject * > key )

inline

Lets us know if a collision had precviously occurred (order independent).

Parameters

key	the combined pair of two worldobject*s

Returns: whether there was a previous collision

Here is the caller graph for this function:

vector< tuple< WorldObject, CollisionObject, WorldObject, CollisionObject > >* Collision::getCollisions	(	WorldObject *	a,
		WorldObject *	b
	)

inline

returns list of collisions

Parameters

a	first object
b	second object

Returns: list of all collisions

Definition at line 83 of file Collision.h.

Here is the caller graph for this function:

void Collision::markCollision	(	WorldObject *	a,
		CollisionObject *	ac,
		WorldObject *	b,
		CollisionObject *	bc
	)

inline

Mark Collision as occurred.

Member Data Documentation

vector< map< Point2D, vector< WorldObject* > > > Collision::Buckets

Buckets into which items fall for collision (determined each loop)

Definition at line 34 of file Collision.h.

unsigned int Collision::CellHeight

The height of partition cells.

Definition at line 37 of file Collision.h.

unsigned int Collision::CellWidth

The width of partition cells.

Definition at line 36 of file Collision.h.

vector< vector< WorldObject* > > Collision::CollisionLists

Sets of collision lists to check detection.

Todo:: make sure that things get removed from this and add at the appropriate time (think streaming maybe instead of hard level boundaries because otherwise we're going to have overlap issues)

Definition at line 33 of file Collision.h.

map< pair< WorldObject*, WorldObject* >, vector< tuple< WorldObject*, CollisionObject*, WorldObject*, CollisionObject* > >* > Collision::Collisions

Map that provides a cache of all collidied objects for a given object (clears each loop) Note:initial key is pair of two objects checking collision, values are world object and associated collision object.

Definition at line 35 of file Collision.h.

Collision * Collision::m_instance = NULL

static

instance of Collision helper
