Detailed Description

The Object Manager.

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

AllStopped()

bool CObjectManager::AllStopped

(

)

Have the balls stopped moving?

Checks whether all of the balls that are still in play (balls that have fallen to the bottom are not in play) have stopped.

Returns

true if all balls in play have stopped.

clear()

void CObjectManager::clear

(

)

Reset to initial conditions.

Delete all of the entities managed by the Object Manager. This involves deleting all of the CObject instances pointed to by the object list, then clearing the object list itself.

CreateBall()

bool CObjectManager::CreateBall

(

)

Create a new ball.

Place a ball in Physics World and the Object Manager. The initial position and velocity is hard-coded.

CreateCounter()

void CObjectManager::CreateCounter

(

int

n

)

Create counter.

Create the counter.

Parameters

n	Number of bits of precision.

CreateWorldEdges()

void CObjectManager::CreateWorldEdges

(

)

Create the edges of the world.

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.

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.
