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.

Here is the caller graph for this function:

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. Also collide objects with the edges of the worlod.

Here is the call graph for this function:

Create()

CObject * CObjectManager::Create	(	eObject	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 Sage::CBaseObjectManager.

Parameters

t	Object type.
pos	Initial position.

Returns

Pointer to the object created.

Here is the caller graph for this function:

FireGun()

void CObjectManager::FireGun

(

CArmedObject *

pObj

)

Create a bullet object and a flash particle effect. The bullet and the muzzle flash appear a little beywod the gun muzzle and the bullet proceeds along the view bector with a random deflection to add some variability.

Parameters

pObj	Pointer to an armed object.

Here is the call graph for this function:

Here is the caller graph for this function:

GetNumGuards()

const UINT CObjectManager::GetNumGuards

(

)

const

Get the number of guards.

Returns

The number of guards.

Here is the caller graph for this function:

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.
