	in case the user wants to free memory explicitly will give that functionality and prevent double deletion plus avoid direct calls to destructor. The game was never intricate enough to need this and we dropped this functionality on later classes. But we might want to extend it in the future.

Detailed Description

Middle-level object that is used for a lot of the map rendering. Occasionally we use it in the game directly when we want to play with transparency levels.

Member Function Documentation

render()

bool TextureWrapper::render	(	SDL_Renderer *	renderer,
		int	x,
		int	y,
		const SDL_Rect *	clip = nullptr,
		double	angle = 0.0f,
		SDL_Point *	center = nullptr,
		SDL_RendererFlip	flip = SDL_FLIP_NONE
	)

Highly customizable rendering function.

Parameters

renderer
x
y
clip	allows to just pick a portion of the texture
angle	allows to rotate the angle
center	allows to rotate upon a central focal point
flip	allows for up-down-left-right flips

Returns

setAlpha()
