Detailed Description

template<class obj>
class Sage::CObjectManager< obj >

A list of game objects with some basic management functions and broad phase collision detection and response. This class is templated so that it can be used to manage game objects declared in individual games. Your game should instantiate it with your game object class, which must be derived from CSage::CObject.

Template Parameters

obj	Object class.

Constructor & Destructor Documentation

CObjectManager()

template<class obj >

Sage::CObjectManager< obj >::CObjectManager

(

)

Default constructor.

Template Parameters

obj	Object class.

~CObjectManager()

template<class obj >

Sage::CObjectManager< obj >::~CObjectManager

(

)

The destructor deletes all of the objects in the object list.

Template Parameters

obj	Object class.

Member Function Documentation

BroadPhase()

template<class obj >

void Sage::CObjectManager< obj >::BroadPhase ( )

protectedvirtual

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

Template Parameters

obj	Object class.

Clear()

template<class obj >

void Sage::CObjectManager< obj >::Clear ( )

virtual

Delete all of the object instances pointed to by the object list, then clear the object list of all pointers so that the object list is empty.

Template Parameters

obj	Object class.

DeleteMarkedObjects()

template<class obj >

void Sage::CObjectManager< obj >::DeleteMarkedObjects ( )

protectedvirtual

Iterate through the objects and check whether each one is ready to delete. If so, then delete it and remove its pointer from the object list.

Template Parameters

obj	Object class.

Draw()

template<class obj >

void Sage::CObjectManager< obj >::Draw ( )

virtual

Move all objects by iterating through all objects in the object list and calling their draw functions.

Template Parameters

obj	Object class.

Insert()

template<class obj >

void Sage::CObjectManager< obj >::Insert ( obj * pObj )

virtual

Insert object.

Insert object into object list.

Parameters

pObj	Pointer to object.

Move()

template<class obj >

void Sage::CObjectManager< obj >::Move ( )

virtual

Move all objects by iterating through all objects in the object list and calling their move functions. Perform broad phase collision detection and response, then delete any dead objects from the object list.

Template Parameters

obj	Object class.

NarrowPhase()

template<class obj >

void Sage::CObjectManager< obj >::NarrowPhase ( obj * p0, obj * p1 )

protectedvirtual

Perform collision detection and response for a pair of objects. This function is a stub.

Template Parameters

obj	Object class.

Parameters

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