  /**
   * Creates a new Curve Shape Game Object and adds it to the Scene.
   *
   * Note: This method will only be available if the Curve Game Object has been built into Phaser.
   * 
   * The Curve Shape is a Game Object that can be added to a Scene, Group or Container. You can
   * treat it like any other Game Object in your game, such as tweening it, scaling it, or enabling
   * it for input or physics. It provides a quick and easy way for you to render this shape in your
   * game without using a texture, while still taking advantage of being fully batched in WebGL.
   * 
   * This shape supports both fill and stroke colors.
   * 
   * To render a Curve Shape you must first create a `Phaser.Curves.Curve` object, then pass it to
   * the Curve Shape in the constructor.
   * 
   * The Curve shape also has a `smoothness` property and corresponding `setSmoothness` method.
   * This allows you to control how smooth the shape renders in WebGL, by controlling the number of iterations
   * that take place during construction. Increase and decrease the default value for smoother, or more
   * jagged, shapes.
   *
   * @method Phaser.GameObjects.GameObjectFactory#curve
   * @since 3.13.0
   *
   * @param {number} [x=0] - The horizontal position of this Game Object in the world.
   * @param {number} [y=0] - The vertical position of this Game Object in the world.
   * @param {Phaser.Curves.Curve} [curve] - The Curve object to use to create the Shape.
   * @param {number} [fillColor] - The color the curve will be filled with, i.e. 0xff0000 for red.
   * @param {number} [fillAlpha] - The alpha the curve will be filled with. You can also set the alpha of the overall Shape using its `alpha` property.
   *
   * @return {Phaser.GameObjects.Curve} The Game Object that was created.
