I constantly get the error 'Instance member isPaused cannot be used on type GameScene'

Question

This is the code I have and I have a button that when I click it, I want to pause the game to show a menu... I have comments where the error is showing up, so you can hopefully see what I'm doing wrong.

Also I'm not sure if this code is supposed to be in my GameScene file, if not could you let me know which one it should be in.

Thanks for trying to help.

        enemy = self.childNode(withName: "enemy") as! SKSpriteNode
        enemy.position.y = (self.frame.height / 2) - 50

        main = self.childNode(withName: "main") as! SKSpriteNode
        main.position.y = (-self.frame.height / 2) + 50

        let border  = SKPhysicsBody(edgeLoopFrom: self.frame)

        border.friction = 0

isPaused is an instance method, not a class method. You need to called it on a specific instance of a SKNode such as your GameScene instance.

Change GameScene.isPaused = true to self.isPaused = true or simply isPaused = true

Besides that issue, you need to move your pauseButton method from inside your didMove(to:) method.

func pauseButton (sender: UIButton) {
    let pauseAction = SKAction.run {
        self.isPaused = true
        debugPrint("Paused")
    }
}

override func didMove(to view: SKView) {
    topLbl = self.childNode(withName: "topLabel") as! SKLabelNode
    btmLbl = self.childNode(withName: "btmLabel") as! SKLabelNode
    ball = self.childNode(withName: "ball") as! SKSpriteNode

    print(self.view?.bounds.height)

    enemy = self.childNode(withName: "enemy") as! SKSpriteNode
    enemy.position.y = (self.frame.height / 2) - 50

    main = self.childNode(withName: "main") as! SKSpriteNode
    main.position.y = (-self.frame.height / 2) + 50

    let border  = SKPhysicsBody(edgeLoopFrom: self.frame)

    border.friction = 0
    border.restitution = 1

    self.physicsBody = border

    startGame()
}

Ok, thanks a-lot it fixed that error, but do you know why after I've done that it shows the error... "Implicit use of 'self' in closure; use 'self'. ta make capture semantics explicit"? — husky, Nov 25 '17 at 10:36
If fixed the answer. Change `isPaused = true` to `self.isPaused = true`. — rmaddy, Nov 25 '17 at 16:19
