Member Function Documentation

AtWorldEdge()

bool CObjectManager::AtWorldEdge ( CObject *  p, Vector2 &  norm, float &  d  ) const

private

Test whether an object's left, right, top or bottom edge has crossed the left, right, top, bottom edge of the world, respectively. If so, then the object's position is corrected. This function assumes that the bottom left corner of the world is at the origin.

Parameters

p	Pointer to an object.
norm	[out] Collision normal.
d	[out] Overlap distance.

Returns

true if the object overlaps the edge of the world.

BroadPhase()

void CObjectManager::BroadPhase ( )

private

Perform collision detection and response for each object with the world edges and for all objects with another object, making sure that each pair of objects is processed only once.

create()

CObject * CObjectManager::create	(	eSprite	t,
		const Vector2 &	pos
	)

Create an object and put a pointer to it at the back of the object list m_stdObjectList, which it inherits from LBaseObjectManager.

Parameters

t	Sprite type.
pos	Initial position.

Returns

Pointer to the object created.

FindClosest()

void CObjectManager::FindClosest	(	const Vector2 &	pos,
		CObject *&	pObj,
		float &	dsq
	)

Find target closest to a position.

Parameters

pos	[in] Position.
pObj	[out] Pointer to closest target, NULL if not found.
dsq	Distance to closest object squared.

FireGun()

void CObjectManager::FireGun	(	CObject *	pObj,
		eSprite	bullet
	)

Create a bullet object and a flash particle effect. It is assumed that the object is round and that the bullet appears at the edge of the object in the direction that it is facing and continues moving in that direction.

Parameters

pObj	Pointer to an object.
bullet	Sprite type of bullet.

NarrowPhase()

void CObjectManager::NarrowPhase ( CObject *  p0, CObject *  p1  )

private

Perform collision detection and response for a pair of objects. Makes use of the helper function Identify() because this function may be called with the objects in an arbitrary order.

Parameters

p0	Pointer to the first object.
p1	Pointer to the second object.
