Trait Scene 

pub trait Scene: Lifecycle {
    // Required methods
    fn on_enter(&mut self);
    fn on_exit(&mut self);
    fn on_render(&self, draw_list: &mut DrawList);
    fn name(&self) -> &str;
}

The base trait for all game scenes.

A scene encapsulates a self-contained portion of the game world, managing its own game objects, resources, and update logic.

Required Methods

fn on_enter(&mut self)

Called once when this scene becomes the active scene.

fn on_exit(&mut self)

Called once when this scene is being replaced or removed.

fn on_render(&self, draw_list: &mut DrawList)

Called every render frame to record the scene’s draw commands.

Instead of drawing immediately, the scene pushes DrawCommands into the provided DrawList; the engine replays the whole list once per frame in a single batched pass.

Arguments

• &mut DrawList - The draw list to record commands into.

fn name(&self) -> &str

Returns the name of this scene for identification.

Returns

• &str - The scene name.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
