## Phaser. PathFollower

#### new PathFollower(path, follower, speed, angleOffset, callbackAtEnd, physicsAdjustTime)

  A PathFollower is a virtual entity that follows the Path.
  It is usually linked to a game object such as a Sprite and it will control either the
  position of that object, or its velocity if it is a physics object.

  Callbacks will be triggered when certain events happen as the follower moves. These
  may be used to aid in the creation of complex behaviours for the game objects.

  ##### Parameters:

  Name | Type | Argument | Default | Description
  --- | --- | --- | --- | ---
  `path` | Phaser.Path |  |  | The Path object which this follower is created on.
  `follower` | Phaser.Sprite | object |  |  | The game object which this follower controls. Requires public properties: `x`, `y` for position and `rotation` for angle control (if specified).
  `speed` | number | <optional> | 1 | The current speed of this follower in pixels per frame. This value is multiplied with the Path segment speed to give the final value used.
  `angleOffset` | number | <optional> | null | If `null` then the PathFollower won't rotate. Otherwise it will face in the paths direction plus this offset which is given in radians.
  `callbackAtEnd` | function | <optional> |  | A callback to be invoked when the follower reaches the end of a path.
  `physicsAdjustTime` | number | <optional> | 0 | If non-zero then the follower expects to control a physics object using "arcade.moveToObject" to control velocity.
