使用 swift - IOS 接触多个节点

Question

编辑为了解决我的问题，我最初忘记将此代码包含到我的代码中，我将它放在这里以供以后遇到相同问题的任何人使用。

override func didMoveToView(view: SKView) {
    self.view?.multipleTouchEnabled = true // --------- set multiple touch
}

我正在制作一个具有 3 个按钮（节点）的游戏，一个向左、向右移动的按钮和一个满足我所有射击需求的开火按钮。无论如何，我想让我的游戏同时识别射击和移动触摸。这是我所有的触摸代码：

override func touchesBegan(touches: Set<UITouch>, withEvent event:   UIEvent?) {
    for touch in touches {
        let location = touch.locationInNode(self)
        let touches = self.nodeAtPoint(location)

        if (touches.name == "rightBtn") {
            rightDown = true
        }

        if (touches.name == "leftBtn") {
            leftDown = true
        }

        if (touches.name == "fireBtn") {
            shooting = true
        }
        if (touches.name == "fireBtn" && touches.name == "rightBtn") {
            rightDown = true
            shooting = true
        }
        if (touches.name == "fireBtn" && touches.name == "leftBtn") {
            leftDown = true
            shooting = true
        }

    }

}
override func touchesMoved(touches: Set<UITouch>, withEvent event: UIEvent?) {
    for touch in touches {
        let location = touch.locationInNode(self)
        let touches = self.nodeAtPoint(location)
        let prevLocation = touch.previousLocationInNode(self)
        let prevLocationTouches = self.nodeAtPoint(prevLocation)

        if (touches.name == "rightBtn" && prevLocationTouches.name == "rightBtn") {
            rightDown = true
            leftDown = false
        } else if (touches.name == "leftBtn" && prevLocationTouches.name == "leftBtn") {
            rightDown = false
            leftDown = true
        } else {
            rightDown = false
            leftDown = false
        }

        if (touches.name == "fireBtn" && prevLocationTouches.name == "fireBtn") {
            shooting = true
        }
        if (touches.name == "fireBtn" && prevLocationTouches.name == "rightBtn") {
            shooting = true
            rightDown = true
        }
        if (touches.name == "fireBtn" && prevLocationTouches.name == "leftBtn") {
            leftDown = true
            shooting = true
        }
    }
}

override func touchesEnded(touches: Set<UITouch>, withEvent event: UIEvent?) {
    for touch in touches {
        let location = touch.locationInNode(self)
        let touches = self.nodeAtPoint(location)

        if (touches.name == "rightBtn") {
            rightDown = false
        } else if (touches.name == "leftBtn") {
            leftDown = false
        } else {
            shooting = false
        }

    }
}

此代码不允许同时进行两次触摸。有什么我想念的吗？

您可能忘记了在视图中启用多点触控？

https://developer.apple.com/library/ios/documentation/UIKit/Reference/UIView_Class/#//apple_ref/occ/instp/UIView/multipleTouchEnabled

When set to YES, the receiver receives all touches associated with a multi-touch sequence. When set to NO, the receiver receives only the first touch event in a multi-touch sequence. The default value of this property is NO.
