Trait gg::scene::Scene [−] [src]

pub trait Scene: HasId {
    type State: Sized + Clone;
    fn enter(&mut self, _state: &mut Self::State) { ... }
    fn leave(&mut self, _state: &mut Self::State) { ... }
    fn keypress(&mut self, _state: &mut Self::State, _keys: &Keys) { ... }
    fn display(&mut self, _state: &mut Self::State, _display: &GlutinFacade) { ... }
    fn tick(&mut self, _state: &mut Self::State, _dt: f64) -> SceneTransition<Self::State> { ... }

One of the most important traits for a game, the scene is what tells the display what to draw as well as what should happen with the given input.

Associated Types

type State: Sized + Clone

What kind of state is carried around?

Provided Methods

fn enter(&mut self, _state: &mut Self::State)

Called everytime this scene becomes the top of the stack

fn leave(&mut self, _state: &mut Self::State)

Called everytime this scene stops being the top of the stack (also before a drop)

fn keypress(&mut self, _state: &mut Self::State, _keys: &Keys)

Convenience method where you can handle keyboard input specifically. This is called before tick.

fn display(&mut self, _state: &mut Self::State, _display: &GlutinFacade)

Called with a display to draw into something

fn tick(&mut self, _state: &mut Self::State, _dt: f64) -> SceneTransition<Self::State>

Called to update the state so as to reflect one advancement in time.
