Member Function Documentation

◆ AnimateJointExplosion()

bool CObjectManager::AnimateJointExplosion ( CObject * p )

private

Animate a joint explosion.

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

Parameters

p	Pointer to an object.

◆ clear()

void CObjectManager::clear ( )

Reset to initial conditions.

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

◆ CreateObject()

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

private

V Create word.

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 random word.

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.

◆ CreateStroopEdges()

void CObjectManager::CreateStroopEdges ( )

Create edges of Stroop caricature.

Create the edges in the Stroop outline so that the words and characters will bounce off him in a satisfactory manner. I laboriously copied down points on Stroop's outline from a screenshot using an image editor when I was too tired to do any real work yet too jazzed up to relax.

◆ 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.

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 ( )

Expire all objects.

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

◆ Draw()

void CObjectManager::Draw ( )

Draw all objects.

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

draw objects in object list

◆ DrawGameText()

void CObjectManager::DrawGameText ( )

Draw game text.

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

◆ DrawScore()

void CObjectManager::DrawScore	(	LSpriteDesc2D &	d,
		int	n
	)

private

Draw score, which may be negatve.

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.

◆ DrawScores()

void CObjectManager::DrawScores ( )

Draw scores.

Draw scores to the window, hopefully over the top of the dashboard, which we assume has been drawn already.

◆ EmitParticle()

void CObjectManager::EmitParticle ( const LParticleDesc2D & d )

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

Parameters

d	Particle descriptor.

◆ EmitSmoke()

void CObjectManager::EmitSmoke	(	const Vector2 &	pos,
		const Vector2 &	vel
	)

private

Emit a puff of smoke.

Create a smoke particle using the front particle engine.

Parameters

pos	Position in Render World coordinates.
vel	Velocity in Render World units.

◆ EmitSpark()

void CObjectManager::EmitSpark	(	const Vector2 &	pos,
		const Vector2 &	vel
	)

private

Emit a spark.

Create a spark particle using the front particle engine.

Parameters

pos	Position in Render World coordinates.
vel	Velocity in Render World units.

◆ ExplodeOldLetters()

void CObjectManager::ExplodeOldLetters ( )

private

Explode old letters.

Explode any individuals letters left over from old words.

◆ ExplodeOldWords()

void CObjectManager::ExplodeOldWords ( )

private

Explode old words.

Find all objects in the object list that are not eWordColor::Gray and are older than WORD_EXPLODE_DELAY and trigger a joint explosion if they are in a joint.

◆ GetCurrentHt()

float CObjectManager::GetCurrentHt ( )

Get the height of the current word.

Get the height of the current word, which is defined to be the average height of the characters in it.

Returns: Average height of current word in Render World units.

◆ GetCurrentPos()

Vector2 CObjectManager::GetCurrentPos ( )

Get the position of the current word.

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

Returns: Position of the current word in Render WOrld coordinates.

◆ GetSize()

const size_t CObjectManager::GetSize ( ) const

Get number of objects.

Reader function for number of objects in the object list.

Returns: Number of objects in object list.

◆ LoadSnideComment()

void CObjectManager::LoadSnideComment ( )

private

Load snide comment into character buffers.

Load a snide comment based on score achieved into the character buffers.

◆ MakeAllExplode()

void CObjectManager::MakeAllExplode ( )

Make all words explode into characters.

Make all words explode by resetting their birth time close to the current time.

◆ MakeCurrentExplode()

void CObjectManager::MakeCurrentExplode ( )

Make the current word explode into characters.

Make the current word explode by resetting its birth time close to the current time.

◆ ProcessShutdown()

void CObjectManager::ProcessShutdown ( )

Initiate shutdown if the game is finished.

Shutdown process to be called when all of the words have been presented to the player.

◆ StroopWatchesCount()

void CObjectManager::StroopWatchesCount ( )

Make the Stroop caricature's eyes swivel towards the current word.

◆ Update()

void CObjectManager::Update ( )

Update all objects.

Update all of the objects in the object list, explode the old words, move the particles in the particle engine, and update the vector field and the Stroop animation.
