# Scenes, game state and timing

## Stages and the state manager

A `Stage` is a screen. Register it against a state id, then change to it:

```js
import { Stage, state } from "melonjs";

class PlayScreen extends Stage {
    onResetEvent(app) { /* build the scene */ }
    onDestroyEvent(app) { /* tear it down */ }
}
