Having problems subclassing an CGpath as an SKShape

I am trying to create four walls, that would surround the screen.

From GameScene I call

Code Block let leftWall  = MyEdge(side: Walls.left)

The code below works. But then I cannot add it as a child to GameScene, also I would like to give it an SKPhysicsBody.

My problem is figuring out the super.init. I've tried

super.init(texture: nil, color: .clear, size: CGPath(w: 0, h: 0))
super.init()

But I always get

Type of expression is ambiguous without more context

Code Block class MyEdge {
    let yourline = SKShapeNode()
    let pathToDraw = CGMutablePath()
    var color : SKColor
    var startAt : CGPoint
    var endAt : CGPoint
    var colMask : UInt32
    var conMask : UInt32
    var catMask : UInt32
    var name : String
    init(side: Walls){
        let whichWall = side
        switch whichWall
        {
            case .left:
				myGlobalVars.backGround!.size.height+1)
                startAt = CGPoint(x: 5, y: 5)
                endAt = CGPoint(x: 5, y: myGlobalVars.safeSceneRect.size.height-5)
                color = .white
                colMask = bodyMasks.gemMask.rawValue
                conMask = bodyMasks.blankMask.rawValue
                catMask = bodyMasks.edgeMask.rawValue
                name = "left"
        }
        pathToDraw.move(to: startAt)
        pathToDraw.addLine(to: endAt)
        yourline.lineWidth = 2
        yourline.path = pathToDraw
        yourline.strokeColor = color
    }
}

Please ignore this question. It shows why I should never be allowed to program. My code is riddled with errors everywhere; not initializing variables, misunderstanding the error msgs I was receiving, etc. etc. etc.

Above that I have to do all that BEFORE calling

Code Block super.init(texture: nil, color: .clear, size: .zero)

Where did you find this initialiser for CGPath

Code Block CGPath(w: 0, h: 0)

Did you try:

Code Block CGPath(rect: .zero, transform: nil)

I've been throwing everything I can, hoping something will stick.

CGPath(rect: .zero, transform: nil)

Produces:

Incorrect argument label in call (have 'rect:transform:', expected 'rect:cornerRadius:')
Replace 'transform' with 'cornerRadius'

Which I do, finally resulting in:

Code Block  super.init(rect: .zero, cornerRadius: CGFloat(0.0))

And the error I get is:

Must call a designated initializer of the superclass 'SKShapeNode'

Could you show the full code of the where you call the initialiser ?

Good you found.

But a few advices to better use the forum and help others to help you:

read the answers and answer to such questions as : "Where did you find this initialiser for CGPath"
post code, otherwise, we get no context. How to find which super.init you call, you don't show this statement in your code.

=> That's absolute need. It is not enough to post code that is not directly relevant.

BTW, you didn't yet tell on what super init is called…
