Detailed Description

The object manager.

The object manager is an abstract representation of all of the objects in the game.

Constructor & Destructor Documentation

~CObjectManager()

CObjectManager::~CObjectManager

(

)

Destructor.

The destructor clears the object list, which destructs all of the objects in it.

Member Function Documentation

clear()

void CObjectManager::clear

(

)

Reset to initial conditions.

Delete all of the entities managed by object manager. This involves deleting all of the CObject instances pointed to by the object list, then clearing the object list itself. Ditto for the line list.

create()

CObject * CObjectManager::create	(	eSprite	t,
		b2Body *	b
	)

Create new object.

Create an object in the object manager.

Parameters

t	Sprite type.
b	Pointer to Physics World body.

Returns

Pointer to the object created.

CreateLine()

CLineObject * CObjectManager::CreateLine	(	b2Body *	b0,
		const b2Vec2 &	d0,
		bool	r0,
		b2Body *	b1,
		const b2Vec2 &	d1,
		bool	r1
	)

Create new line object.

Create a line object in object manager. Lines have their own list do that they can be drawn behind the other objects.

Parameters

b0	Pointer to first physics body. (The base.)
d0	Vector offset to anchor point on b0.
r0	Radius of b0.
b1	Pointer to second physics body. (The dangly bit.)
d1	Vector offset to anchor point on b1.
r1	Radius of b1.

Returns

Pointer to line object.

CreateWorldEdges()

void CObjectManager::CreateWorldEdges

(

)

Create world edges.

Create world edges in Physics World. Place Box2D edge shapes in the Physics World in places that correspond to the bottom, right, and left edges of the screen in Render World. The left and right edges continue upwards for a distance. There is no top to the world.

DeleteObject()

bool CObjectManager::DeleteObject

(

eSprite

t

)

Delete the first object of a given sprite type.

Delete the first object of a given sprite type.

Parameters

t	Sprite type.

Returns

true if one was actually deleted.

draw()

void CObjectManager::draw

(

)

Draw all objects.

Draw the game objects using Painter's Algorithm. The background is drawn first, then the game objects are asked to draw themselves in the order that they are in the object list. That is, they are drawn from back to front. The lines are drawn behind the objects.
