asw::display Namespace Reference

Functions
void	_init (int width, int height, int scale)
	Initialize the display module. Called by asw::core::init().
void	_init_opengl (int width, int height, int scale)
	Initialize the display module with OpenGL support. Called by asw::core::init().
void	_shutdown ()
	Shut down the display module. Called by asw::core::shutdown(). Nulls the renderer and window pointers before destroying them, so any outstanding shared_ptr asset deleters see a null renderer and become no-ops.

	Get the SDL window.
void	set_title (const std::string &title)
	Set the title of the window.

	Get the logical size of the window. This may differ from the actual size if scaling is enabled.
asw::Vec2< float >	get_scale ()
	Get the scale of the window. This is equivalent to the logical size divided by the actual size.
