+     * Generate an array of {@link Phaser.Types.Animations.AnimationFrame} objects from a texture key and configuration object.
+     *
+     * Generates objects with string based frame names, as configured by the given {@link Phaser.Types.Animations.GenerateFrameNames}.
+     *
+     * It's a helper method, designed to make it easier for you to extract all of the frame names from texture atlases.
+     * If you're working with a sprite sheet, see the `generateFrameNumbers` method instead.
+     *
+     * Example:
+     *
+     * If you have a texture atlases loaded called `gems` and it contains 6 frames called `ruby_0001`, `ruby_0002`, and so on,
+     * then you can call this method using: `this.anims.generateFrameNames('gems', { prefix: 'ruby_', end: 6, zeroPad: 4 })`.
+     *
+     * The `end` value tells it to look for 6 frames, incrementally numbered, all starting with the prefix `ruby_`. The `zeroPad`
+     * value tells it how many zeroes pad out the numbers. To create an animation using this method, you can do:
+     *
+     * ```javascript
+     * this.anims.create({
+     *   key: 'ruby',
+     *   repeat: -1,
+     *   frames: this.anims.generateFrameNames('gems', {
+     *     prefix: 'ruby_',
+     *     end: 6,
+     *     zeroPad: 4
+     *   })
+     * });
+     * ```
+     *
+     * Please see the animation examples for further details.

+     *
+     * The `end` value tells it to stop after 12 frames. To create an animation using this method, you can do:

+     *   })
+     * });
+     * ```
+     *
+     * Note that `start` is optional and you don't need to include it if the animation starts from frame 0.
+     *
+     * To specify an animation in reverse, swap the `start` and `end` values.
+     *
+     * If the frames are not sequential, you may pass an array of frame numbers instead, for example:
+     *
+     * `this.anims.generateFrameNumbers('explosion', { frames: [ 0, 1, 2, 1, 2, 3, 4, 0, 1, 2 ] })`
