Trait gate::App

pub trait App<A: AppAssetId> {
    fn advance(&mut self, seconds: f64, audio: &mut Audio<A>) -> bool;
    fn input(
        &mut self, 
        event: KeyEvent, 
        key: KeyCode, 
        audio: &mut Audio<A>
    ) -> bool;
    fn render(&mut self, renderer: &mut Renderer<A>);

    fn start(&mut self, _audio: &mut Audio<A>) { ... }
}

Trait that a user can implement to specify application behavior, passed into gate::run(...).

Required Methods

fn advance(&mut self, seconds: f64, audio: &mut Audio<A>) -> bool

Advances the app state by a given amount of seconds (usually a fraction of a second).

fn input(&mut self, event: KeyEvent, key: KeyCode, audio: &mut Audio<A>) -> bool

Invoked when user input is received (currently only keyboard presses/releases).

fn render(&mut self, renderer: &mut Renderer<A>)

Render the app in its current state.

Provided Methods

fn start(&mut self, _audio: &mut Audio<A>)

Invoked when the application is first started, default behavior is a no-op.
