### Dynamically Install Scene Plugin in init()

Source: https://docs.phaser.io/phaser/concepts/scenes

This example illustrates how to dynamically install a default plugin (TweenManager) into a Phaser Scene after it has been created, using the `init` method. This approach is beneficial when the need for a plugin is determined during the scene's initialization phase.

```javascript
class BootScene extends Phaser.Scene {
    constructor() {
        super({
            key: 'boot',
            plugins: []
        });
    }

    init() {
        this.sys.install('TweenManager');
    }
}
```

### Two-Scene Game Structure (Boot and Play)

Source: https://docs.phaser.io/phaser/concepts/scenes

Provides a concrete example of a two-scene game structure, with a 'Boot' scene for loading assets and a 'Play' scene for game logic. The 'Boot' scene is configured to start automatically.

```javascript
class Boot extends Phaser.Scene {
  // Load assets
  preload() {}

  // Start Play scene
  create() {}
}

class Play extends Phaser.Scene {
  // Create game objects with loaded assets
  create() {}

  // Update the scene
  update() {}
}

new Phaser.Game({
  scene: [
    // Only 'boot' will start.
    new Boot("boot"),
    new Play("play"),
  ],
});
```

--------------------------------

### Transitioning between scenes using start()

Source: https://docs.phaser.io/phaser/concepts/scenes

Demonstrates how to transition from one scene to another using the start() method. This method stops the calling scene and starts the target scene.

```javascript
// In scene A: stop A, start B
this.scene.start("B");

// In scene B: stop B, start C
this.scene.start("C");

// In scene C: stop C, start A again
this.scene.start("A");
```

### Animation Creation Examples

Source: https://docs.phaser.io/phaser/concepts/animations

Provides practical examples of creating animations using different methods, including using all frames from a texture, selecting specific frames, and generating animations from multiple textures.

```APIDOC
## POST /anims/create Examples

### Description
Illustrates various ways to define animations using `this.anims.create()`.

### Method
POST

### Endpoint
/anims/create

### Examples
#### 1. Use every frame in a texture
Creates an animation named 'mummyWalk' using all frames from the 'mummy' texture.
```javascript
this.anims.create({
  key: "mummyWalk",
  frames: "mummy"
});
```

#### 2. Choosing specific texture frames by index
Creates an animation named 'mummyWalk' using frames 0, 1, and 2 from the 'mummy' texture.
```javascript
this.anims.create({
  key: "mummyWalk",
  frames: [
    { key: "mummy", frame: 0 },
    { key: "mummy", frame: 1 },
    { key: "mummy", frame: 2 }
  ]
});
```

#### 3. Creating animations from multiple textures with shared frame patterns
Generates animations like 'giant:idle', 'elf:walk', etc., by iterating through texture keys and predefined animation sequences.
```javascript
const textureKeys = ["giant", "elf", "goblin"];
const anims = {
  idle: [0],
  walk: [1, 2],
  attack: [3, 4]
};

for (const textureKey of textureKeys) {
  for (const animName in anims) {
    this.anims.create({
      key: `${textureKey}:${animName}`,
      frames: anims[animName].map(frameIndex => ({ key: textureKey, frame: frameIndex }))
    });
  }
}
```
