no designated init for SKShapeNode(circleOfRadius: radius)

Question

I'm trying to create a subclass of SKShapeNode in swift as SKShapeNode(circleOfRadius: radius) but there is no designated init for it.

Anyone have any workarounds or info about why? I'm not sure if this is a bug or intentional. I found this video demonstrating a workaround for SKSpriteNode but its not working for me. https://skillsmatter.com/skillscasts/5695-how-to-subclass-a-skspritenode

Overall i am trying to make a subclass for an SKShapeNode that i can then subclass from again to have different versions of to easier manage my code. TIA

Thanks Martin i found that example earlier. It works but how would i make that into a circle instead of a rectangle?

import Foundation
import SpriteKit


    class Player : SKShapeNode {

        override init() {
            super.init()
            self.name = "Player"
            self.fillColor = UIColor.blackColor()

        }

        init(rectOfSize: CGSize) {
            super.init()

            var rect = CGRect(origin: CGPointZero, size: rectOfSize)
            self.path = CGPathCreateWithRect(rect, nil)
        }

        required init?(coder aDecoder: NSCoder) {
            fatalError("init(coder:) has not been implemented")
        }
    }

In Main Code

let playerOne = Player(rectOfSize: CGSize(width: 100, height: 100))

Answer 1

how's this?

class Player: SKShapeNode {

    init(circleOfRadius: CGFloat){
        super.init()

        let diameter = circleOfRadius * 2
        self.path = CGPathCreateWithEllipseInRect(CGRect(origin: CGPointZero, size: CGSize(width: diameter, height: diameter)), nil)
    }

    required init?(coder aDecoder: NSCoder) {
        fatalError("init(coder:) has not been implemented")
    }

}
