Function Documentation

CreateCircleOutlineTexture()

SDL_Texture * CreateCircleOutlineTexture	(	int	radius,
		SDL_Color	color,
		int	thickness
	)

Creates a texture containing an unfilled circle.

Parameters

radius	Radius of the circle
color	Color of the circle outline
thickness	Line thickness (1 for thin outline)

Returns

SDL_Texture* containing the circle outline

CreateCircleTexture()

SDL_Texture * CreateCircleTexture	(	int	radius,
		SDL_Color	color
	)

CreateHalfCircleOutlineTexture()

SDL_Texture * CreateHalfCircleOutlineTexture	(	int	radius,
		Vec2	direction,
		SDL_Color	color,
