Virtual alternative analog joystick

============================

Initialization

UIImage bgImage = UIImage(named: "bgImage")
UIImage thumbImage = UIImage(named: "thumbImage")

1. With background and thumb image:
   

   let analogstick = AnalogStick(thumbImage: thumbImage, bgImage: bgImage)

2. With thumb image:
   

   let analogstick = AnalogStick(thumbImage: thumbImage)

3. With background image:
   

   let analogstick = AnalogStick(bgImage: bgImage)

analogstick.position = CGPointMake(CGRectGetMidX(self.frame), CGRectGetMidY(self.frame)) // center position
self.addChild(analogstick)

============================

AnalogStickProtocol

@objc protocol AnalogStickProtocol { func moveAnalogStick(analogStick: AnalogStick, velocity: CGPoint, angularVelocity: Float) }
func moveAnalogStick(analogStick: AnalogStick, velocity: CGPoint, angularVelocity: Float) - change position of the cursor

• var thumbNodeDiametr: CGFloat // get/set thumb node diametr
• let thumbNode: SKSpriteNode, bgNode: SKSpriteNode // thumb & background nodes (readonly)

============================

Methods

• func setBgImage(image: UIImage?, sizeToFit: Bool) // set background node image; sizeToFit - resize or not resize to image size
• func setThumbImage(image: UIImage?, sizeToFit: Bool) // set thumb node image; sizeToFit - resize or not resize to image size
