Phaser Class: 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.
