Detailed Description

Creates a Texture for use with a renderer Creates a Texture from an image file, this can then be used with a renderer. DISCLAIMER - This code is from my PGG SDL Assignment.

Constructor & Destructor Documentation

Texture::Texture	(	SDL_Renderer *	renderer,
		int	r,
		int	g,
		int	b
	)

Constructs a Texture Creates a Texture using an rbg value. This will create a 1x1 rectangle of that colour that can be scaled.

Parameters

std::string	The location of the image file.
int	r
int	g
int	b

Texture::Texture	(	std::string	fileName,
		SDL_Renderer *	renderer
	)

Constructs a Texture Creates a Texture using an image location and a renderer. This is for use with SDL image.

Parameters

std::string	The location of the image file.
SDL_Renderer*	The renderer.

Texture::Texture	(	std::string	fileName,
		SDL_Renderer *	renderer,
		bool	magentaAlpha
	)

Constructs a Texture Creates a Texture using an image location and a renderer. The magenta pixels of this image can represent alpha if needed.

Parameters

std::string	The location of the image file.
SDL_Renderer*	The renderer.
bool	If true any magenta pixels in the image will be converted to alpha

Texture::~Texture

(

)

Destructs a Texture Destructs the Texture deleting the Texture from memory.

Getter # Returns textureWidth Returns the value of textureWidth.

void Texture::pushSpriteToScreen	(	SDL_Renderer *	renderer,
		int	x,
		int	y,
		int	srcX,
		int	srcY,
		int	srcWidth,
		int	srcHeight
	)

Pushes the image to the Renderer, to the XY Coordinates. Only displays the source rectangle inputed.

Parameters

SDL_Renderer*	The renderer.
int	x coordinate of the image.
int	y coordinate of the image.
int	x coordinate of the source image.
int	y coordinate of the source image.
int	width of the source image.
int	height of the source image.

Here is the caller graph for this function:

void Texture::pushSpriteToScreen	(	SDL_Renderer *	renderer,
		int	x,
		int	y,
		int	srcX,
		int	srcY,
		int	srcWidth,
		int	srcHeight,
		int	width,
		int	height
	)

Pushes the image to the Renderer, to the XY Coordinates. Only displays the source rectangle inputed. This is scaled to the width and height inputed.

Parameters

SDL_Renderer*	The renderer.
int	x coordinate of the image.
int	y coordinate of the image.
int	x coordinate of the source image.
int	y coordinate of the source image.
int	width of the source image.
int	height of the source image.
int	width of the scaled image.
int	height of the scaled image.

void Texture::pushToScreen	(	SDL_Renderer *	renderer,
		int	x,
		int	y
	)

Pushes the image to the Renderer, to the XY Coordinates.

Parameters

SDL_Renderer*	The renderer.
int	x coordinate of the image.
int	y coordinate of the image.

Here is the caller graph for this function:

void Texture::pushToScreen	(	SDL_Renderer *	renderer,
