Detailed Description

The object manager is 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

AllCratesBelow()

const bool CObjectManager::AllCratesBelow

(

float

h

)

const

Parameters

h	Height in Render World units.

Returns

true if all crates have y-coordinate less than h.

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:

CreateBackground()

void CObjectManager::CreateBackground

(

eSprite

t

)

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.

Parameters

t	Sprite type.

Here is the caller graph for this function:

CreateCrate()

void CObjectManager::CreateCrate ( float x, float y, const b2FixtureDef & fd )

private

Create a crate in Physics World and Object World.

Parameters

x	Horizontal coordinate in Physics World units.
y	Vertical coordinate in Physics World units.
fd	Crate fixture definition.

Here is the caller graph for this function:

CreateObject()

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

Create an object in the object manager.

Parameters

t	Sprite type.
p	Pointer to Physics World body.

Here is the caller graph for this function:

CreateTower()

void CObjectManager::CreateTower

(

)

Create a tower of crates at a hard-coded location.

Here is the call graph for this function:

Here is the caller graph for this function:

EmitSmoke()

void CObjectManager::EmitSmoke	(	const Vector2 &	p,
		Vector2	v )

Create a smoke particle using the front particle engine so that it appears in front of the cannon. This particle will scale in and fade out over its lifespan, which is hard-coded. Friction is added to make it slow down horizontally, and upward acceleration is added to make it appear to rise due to the high temperature of an expolosion.

Parameters

p	Initial position.
v	Initial velocity.

Here is the caller graph for this function:

MakeCollisionSounds()

void CObjectManager::MakeCollisionSounds

(

)

Make collision sounds for all objects.
