pub trait Delegate {
    // Required methods
    fn tick(
        &mut self,
        context: &mut ApplicationContext,
        key_manager: &KeyManager,
        mouse_state: &MouseState,
        delegate_spawner: &mut DelegateSpawner,
    );
    fn render(&self, graphics: &mut Graphics);

    fn on_spawn(&mut self, _delegate_spawner: &mut DelegateSpawner) { ... }
    fn render_order(&self) -> i32 { ... }
}

Trait for defining an interface for objects receiving updates from the application.

The order of objects receiving updates is opaque and subject to change.

Required Methods

fn tick( &mut self, context: &mut ApplicationContext, key_manager: &KeyManager, mouse_state: &MouseState, delegate_spawner: &mut DelegateSpawner, )

The order in which tick is called is opaque, do not depend on it.

fn render(&self, graphics: &mut Graphics)

Render the object, the order in which render is called depends on the render_order.

Provided Methods

fn on_spawn(&mut self, _delegate_spawner: &mut DelegateSpawner)

Optional method to do things on spawn

fn render_order(&self) -> i32

Objects that have a higher render_order will be rendered on top of objects with a lower order. Changing the render_order after spawn is not yet supported.
