AnimateJointExplosion()

bool CObjectManager::AnimateJointExplosion ( CObject * p )

private

Animate the explosion of a joint using the particle engine and vector field.

Parameters

p	Pointer to an object.

Returns

true if the object has a joint, false otherwise.

Clear()

void CObjectManager::Clear

(

)

Reset back to initial conditions. This involves deleting all of the CObject instances pointed to by the object list, then clearing the object list.

Here is the caller graph for this function:

CreateObject()

CObject * CObjectManager::CreateObject ( const CObjDesc & d )

private

Create new object.

Create an object of a specified type, enter it into the object list, and return a pointer to it.

Parameters

d	Object descriptor.

Returns

Pointer to the object created.

CreateRandomWord()

void CObjectManager::CreateRandomWord

(

)

Create a word that reads "red", "green", or "blue" pseudorandomly, to be rendered in red, green, or blue chosen pseudorandomly. The initial position of the word is pseudorandmly offset a small amount from the window center line, just above the window so that it is initially out of sight.

CreateWord()

void CObjectManager::CreateWord ( const b2Vec2 & pos, char * txt, float s, eWordColor clr )

private

Parameters

pos	Position in Physics World.
txt	Word in text format, zero terminated.
s	Scale.
clr	Color that text is to be rendered in.

CreateWorldEdges()

void CObjectManager::CreateWorldEdges

(

)

Create world edges in Physics World. Place Box2D edge shapes in the Physics World in places that correspond to the top, 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.

DeactivateCurrent()

void CObjectManager::DeactivateCurrent

(

)

Make the current word's color eWordColor::Black.

Draw()

void CObjectManager::Draw

(

)

Draw the game objects using Painter's Algorithm:eSprite::Background, then the objects in the object list, then the particles in the particle engine.

DrawGameText()

void CObjectManager::DrawGameText

(

)

Draw game text appropriate to the game state, including the countdown timer.

DrawScore()

void CObjectManager::DrawScore ( Sage::CSpriteDesc2D & d, int n )

private

Draw a single score. It is assumed that the score is greater than -100 and less than or equal to 100. Bad things happen otherwise.

Parameters

d	[in, out] Sprite descriptor.
n	Score.

EmitParticle()

void CObjectManager::EmitParticle

(

const Sage::CParticleDesc2D &

d

)

Create a particle using the front particle engine. This is a public member function because the contact listener needs to call it.

Parameters

Here is the caller graph for this function:

ExplodeOldWords()

void CObjectManager::ExplodeOldWords ( )

GetCurrentPos()

Vector2 CObjectManager::GetCurrentPos

(

)

Get the position of the current word in Render World units. This is obtained by averaging the positions of the letters in it.
