*
* To enable this Game Object for physics you need to call `game.physics.enable(object, system)` where `object` is this object
* and `system` is the Physics system you are using. If none is given it defaults to `Phaser.Physics.Arcade`.
*
* You can alternatively call `game.physics.arcade.enable(object)`, or add this Game Object to a physics enabled Group.
*
* Important: Enabling a Game Object for P2 or Ninja physics will automatically set its `anchor` property to 0.5,
* so the physics body is centered on the Game Object.
*
* If you need a different result then adjust or re-create the Body shape offsets manually or reset the anchor after enabling physics.
