Constructor & Destructor Documentation

SlTextureManager::SlTextureManager

(

SlManager *

manager

)

Initializes SDL, creates window with name and width, height

SlTextureManager::SlTextureManager ( const SlTextureManager &  )

delete

Delete copy constructor. The manager owns the window, don't want copies of that.

SlTextureManager::SlTextureManager ( void  )

protected

Default constructor.

Member Function Documentation

void SlTextureManager::addTexture ( SlTexture *  toAdd )

protected

Adds toAdd to textures_ and creates SlSprite of same name.

void SlTextureManager::clear ( )

protected

Deletes all textures and sprites, empties render queue.

SlTexture * SlTextureManager::createTextureFromFile	(	const std::string &	name,
		const std::string &	filename
	)

Load texture from image filename

SlTexture * SlTextureManager::createTextureFromRectangle	(	const std::string &	name,
		int	width,
		int	height,
		uint8_t	red,
		uint8_t	green,
		uint8_t	blue,
		uint8_t	alpha = 0xFF
	)

Creates SlTexture using a rectangle of dimension width x height filled with the specified colour.
Creates SlSprite of same name that holds the whole texture.

SlTexture * SlTextureManager::createTextureFromSpriteOnTexture	(	const std::string &	name,
		const std::string &	backgroundTexture,
		const std::string &	foregroundSprite
	)

Create a new texture by rendering a sprite on this texture.
Creates SlSprite of same name that holds the whole texture.

SlTexture * SlTextureManager::createTextureFromText	(	const std::string &	name,
		const std::string &	fontname,
		const std::string &	message,
		int	width
	)

Create a new texture from the message using the specified font. The text will be wrapped to fit the width.

SlTexture * SlTextureManager::createTextureFromTile	(	const std::string &	name,
		const std::string &	sprite,
		int	width,
		int	height
	)

Creates a new texture with dimensions w x h and fills it with tiles of SlSprite tile.
Creates SlSprite of same name that holds the whole texture.

The SlRenderSettings::destinationRect at position 0 in the SlSprite::destinations_ is used to determine the width of the tile. If the SlSprite::destinations_ is empty, addDefaultDestination() is called which sets the destinationRect to equal the sourceRect.

void SlTextureManager::deleteTexture

(

const std::string &

name

)

Delete the specified texture and remove from textures_ .
Also deletes the SlSprite of same name that was created automatically with the texture.

std::shared_ptr< SlFont > SlTextureManager::findFont

(

const std::string &

name

)

Returns pointer to the named font.

Return values

nullptr

if not found

SlTexture * SlTextureManager::findTexture

(

const std::string &

name

)

Returns pointer to the named texture.

Return values

nullptr

if not found

SlTextureManager& SlTextureManager::operator= ( const SlTextureManager &  )

delete

Deleted, same reason as copy constructor.

std::shared_ptr< SlFont > SlTextureManager::parseFont

(

std::ifstream &

input

)

Read font file, size, colour from file

SlTexture * SlTextureManager::parseTexture

(

std::ifstream &

input

)

Read texture configurations from file

<- message[0] is space between token and beginning of text.

Member Data Documentation

std::vector<std::shared_ptr<SlFont> > SlTextureManager::fonts_

private

Font used for rendering. This is kept open until program exits to reduce overhead from opening and closing font file.

SlManager* SlTextureManager::mngr_ = nullptr

private

Pointer to the running SlManager that created this TextureManager.

std::vector<SlTexture*> SlTextureManager::textures_

private

Holds all SlTextures that were created using SlTextureManager methods. Texture will be deleted when the SlTextureManager instance is deleted.

SlValueParser* SlTextureManager::valParser = nullptr

Helper object to translate file input into values.
