Trait ggez::graphics::Drawable

pub trait Drawable {
    fn draw(&self, ctx: &mut Context, param: DrawParam) -> GameResult;
    fn dimensions(&self, ctx: &mut Context) -> Option<Rect>;
    fn set_blend_mode(&mut self, mode: Option<BlendMode>);
    fn blend_mode(&self) -> Option<BlendMode>;
}

All types that can be drawn on the screen implement the Drawable trait.

Required methods

fn draw(&self, ctx: &mut Context, param: DrawParam) -> GameResult

Draws the drawable onto the rendering target.

fn dimensions(&self, ctx: &mut Context) -> Option<Rect>

Returns a bounding box in the form of a Rect.

It returns Option because some Drawables may have no bounding box (an empty SpriteBatch for example).

fn set_blend_mode(&mut self, mode: Option<BlendMode>)

Sets the blend mode to be used when drawing this drawable. This overrides the general graphics::set_blend_mode(). If None is set, defers to the blend mode set by graphics::set_blend_mode().

fn blend_mode(&self) -> Option<BlendMode>

Gets the blend mode to be used when drawing this drawable.
