游戏结束后如何删除此功能？

Question

我有这个功能，我想在游戏结束后删除它。我尝试使用removeActionWithKey，但似乎没有用。一旦游戏结束，还有其他方法可以删除吗？

 func doAction() {
    let generateCircles = SKAction.sequence([
        SKAction.runBlock(self.circleRandom),
        SKAction.waitForDuration(1.5)])
    let endlessAction = SKAction.repeatActionForever(generateCircles)
    runAction(endlessAction)
}


 if firstBody.categoryBitMask == HeroCategory && secondBody.categoryBitMask == RedCategory {

    //Tried to remove the func here but that doesn't work.     
    removeActionForKey("stop")
}


    override func touchesEnded(touches: Set<UITouch>, withEvent event: UIEvent?) {
    touchingScreen = false

    if let touch = touches.first {
        let location = touch.locationInNode(self)
        let node = self.nodeAtPoint(location)

        if node.name == "start" {

            startGame.removeFromParent()

            //Calling the doAction func here once start button is pressed.

            let action = SKAction.runBlock(doAction)

            runAction(action, withKey: "stop")


        }

    }
}

Answer 1

将runAction(endlessAction)替换为runAction(endlessAction, withKey: "endlessAction1")

然后致电

removeActionForKey("stop")
removeActionForKey("endlessAction1")

你希望它停止的地方。
