Detailed Description

An abstract representation of all of the objects in the game.

Constructor & Destructor Documentation

~CObjectManager()

CObjectManager::~CObjectManager

(

)

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

Here is the call graph for this function:

Member Function Documentation

AllStopped()

bool CObjectManager::AllStopped

(

)

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.

Here is the caller graph for this function:

clear()

void CObjectManager::clear

(

)

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.

Here is the caller graph for this function:

CreateBall()

bool CObjectManager::CreateBall

(

)

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

Returns

true if the ball was successfully created.

Here is the call graph for this function:

Here is the caller graph for this function:

CreateCounter()

void CObjectManager::CreateCounter

(

UINT

n

)

Create the counter.

Parameters

n	Number of bits of precision.

Here is the call graph for this function:

Here is the caller graph for this function:

CreateObject()

void CObjectManager::CreateObject	(	eSprite	t,
		b2Body *	p )

Create an object in the Object Manager and link its Physics World body to it.

Parameters

t	Sprite type.
p	Pointer to Box2D body.

Here is the caller graph for this function:

CreateWorldEdges()

void CObjectManager::CreateWorldEdges

(

)

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.

Here is the call graph for this function:

Here is the caller graph for this function:

draw()

void CObjectManager::draw

(

)

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.

Here is the caller graph for this function:

HighLightBit()

int CObjectManager::HighLightBit

(

UINT

n

)

Highlight a bit.

Parameters

n	Index of bit.

Returns

0 if the bit is zero, 1 if the bit is one.

Here is the call graph for this function:

Here is the caller graph for this function:

Overflow()

const bool CObjectManager::Overflow

(

)

const

Check for overflow.

Returns

true if there has been an overflow.
