Constructor & Destructor Documentation

SlManager::SlManager ( )

Default constructor. Parses "SlApplication.ini" for window name and dimensions, and configuration file names.

SlManager::SlManager	(	const std::string &	name,
		int	width,
		int	height
	)

Initializes SDL, creates window with name and width, height

SlManager::SlManager ( const SlManager & )

delete

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

Member Function Documentation

bool SlManager::appendToRenderQueue	(	const std::string &	name,

false if sprite not found or destination out of bounds.

void SlManager::clear ( )

protected

Deletes all textures and sprites, empties render queue.

SlRenderItem * SlManager::createRenderItem	(	const std::string &	name,
		unsigned int	destination
	)

Creates new SlRenderItem for the specified sprite.

Return values

nullptr if sprite not found or destination out of bounds.

void SlManager::deleteRenderItem ( const std::string & name )

Delete all render items with the specified name from the renderQueue_ . Should be called before deleteSprite(const std::string& name).

void SlManager::deleteSprite ( const std::string & name )

Tells smngr_ to delete the specified sprite. Also deletes all associated entries in renderQueue_ .

void SlManager::deleteTexture ( const std::string & name )

Tells tmngr_ to delete the specified texture and remove from SlTextureManager::textures_ . Also deletes all associates SlSprites.

std::shared_ptr< SlSprite > SlManager::findSprite ( const std::string & name )

Returns pointer to the sprite, nullptr if not found.

SlTexture * SlManager::findTexture ( const std::string & name )

Returns pointer to the texture, nullptr if not found. Calls SlTextureManager tmngr_ .

void SlManager::handleEvent ( const SDL_Event & event )

inline

Pass event on to SlEventHandler eventHandler_ . Deprecated, just call run().

void SlManager::initialize ( )

protected

Initializes SDL

< Needs to be shared with SlRenderQueueManipulation items.

void SlManager::initializeWindow	(	const std::string &	name,
		int	width,
		int	height
	)

protected

Initializes window

void SlManager::insertInRenderQueueAfter	(	const std::string &	toAdd,
		const std::string &	afterThis,
		unsigned int	destToAdd = `0`,
		unsigned int	destAfterThis = `0`
	)

Inserts the sprite into the renderQueue_ after the specified sprite.

void SlManager::insertInRenderQueueBefore	(	const std::string &	toAdd,
		const std::string &	beforeThis,
		unsigned int	destToAdd = `0`,
		unsigned int	destBeforeThis = `0`
	)

Inserts the sprite into the renderQueue_ before the specified sprite.

void SlManager::manipulateRenderQueue	(	const std::string &	name,
		unsigned int	destination,
		const std::string &	whatToDo,
		const std::vector< std::string > &	parameters
	)

Move the render item based on configuration file.\ Currently implemented whatToDo:
append

bool SlManager::moveInRenderQueue	(	const std::string &	toMoveName,
		const std::string &	targetName,
		unsigned int	destToMove = `0`,
		unsigned int	targetDest = `0`,
		int	beforeOrAfter = `0`
	)

protected

Moves a SlRenderItem's position in the renderQueue_ to before of after the target item.
beforeOrAfter is 0 for before, 1 for after. Larger (smaller) values will result in the target item begin inserted further upstream (downstream) of the target. (Handle with care, currently no test for valid iterators beyond +1...)

bool SlManager::moveInRenderQueueAfter	(	const std::string &	toAdd,
		const std::string &	afterThis,
		unsigned int	destToAdd = `0`,
		unsigned int	destAfterThis = `0`
	)

Moves the render item into the renderQueue_ after the specified sprite.

bool SlManager::moveInRenderQueueBefore	(	const std::string &	toAdd,
		const std::string &	beforeThis,
		unsigned int	destToAdd = `0`,
		unsigned int	destBeforeThis = `0`
	)

Moves the render item into the renderQueue_ before the specified sprite.

SlManager& SlManager::operator= ( const SlManager & )

delete

Deleted, same reason as copy constructor.

bool SlManager::parseConfigurationFile ( const std::string & filename = "SlTextureConfig.ini" )

Read texture and sprite definitions from configuration file.
Default file name: "SlTextures.ini".

void SlManager::parseIniFile ( const std::string & filename = "SlApplication.ini" )

Reads application name, screen dimensions and config file names from from ini file "SlApplication.ini".

void SlManager::parseRenderQueueManipulation ( std::ifstream & input )

Add sprites to render queue, change to order of the queue. (Currently only implemented: append.)

void SlManager::render ( )

Render all items in the renderQueue_ .

Return values

0	if all renders well.

SDL_Renderer* SlManager::renderer ( )

inline

Temporary solution until all rendering related stuff happens in SlManager methods.

void SlManager::run ( )

Run the event - render loop.

int SlManager::screenHeight ( )

inline

int SlManager::screenWidth ( )

inline

Returns the screen_width_ of the window.

void SlManager::setSpriteColor	(	const std::string &	name,

		uint8_t	blue,
		uint8_t	alpha = `0xFF`,
		unsigned int	destination = `0`

false if sprite not found or destination out of bounds.

void SlManager::swapInRenderQueueAtPosition	(	const std::string &	toAdd,
		unsigned int	destToAdd,
		unsigned int	position
	)

Replaces the SlRenderItem at 'position' in the renderQueue_ with sprite 'toAdd'.
Note that the first item is in position 0.

void SlManager::swapInRenderQueueLastPosition	(	const std::string &	toAdd,
		unsigned int	destToAdd = `0`
	)

Replaces the last item in the renderQueue_ with sprite toAdd.

void SlManager::toggleRender	(	const std::string &	toToggle,
		unsigned int	destination = `0`,
		int	onOrOff = `-1`
	)

Toggles rendering of an item in the renderQueue_ on and off. onOrOff is -1 to toggle, 0 to turn off, 1 to turn on.

void SlManager::toggleRenderOff	(	const std::string &	toToggle,
		unsigned int	destination = `0`
	)

inline

Turns off rendering for the specified SlRenderItem in the renderQueue_ .

void SlManager::toggleRenderOn	(	const std::string &	toToggle,

std::unique_ptr<SlEventHandler> SlManager::eventHandler_ = nullptr

private

Event handler, parses events in configuration file, triggers SlManipulation on key input.

SDL_Renderer* SlManager::renderer_ = nullptr

protected

The renderer tied to the main window.

std::map<std::string, SlManipulation*> SlManager::renderManip_

private

private

Holds the items to be rendered. The front of the queue is rendered first (background) the last element is rendered last (foreground).

int SlManager::screen_height_

private

Window height

int SlManager::screen_width_

private

Window width.

std::shared_ptr<SlSpriteManager> SlManager::smngr_ = nullptr

private

Sprite manager, creates, stores, manipulates, and deletes SlSprite objects.

std::unique_ptr<SlTextureManager> SlManager::tmngr_ = nullptr

private

Texture manager, creates, stores, deletes SlTexture objects.

SlValueParser SlManager::valParser_

private

Helper object to translate file input into values.

SDL_Window* SlManager::window_ = nullptr

protected

The main (and only) window.
