设置追踪镜头

  let configuration = AROrientationTrackingConfiguration()//追踪镜头的位置，只有三个自由度 速度比较快

在viewcontroller中设置点击为炸弹

  func view(_ view: ARSKView, nodeFor anchor: ARAnchor) -> SKNode? {
        // Create and configure a node for the anchor added to the view's session.
        let labelNode = SKLabelNode(text: "")
        labelNode.horizontalAlignmentMode = .center
        labelNode.verticalAlignmentMode = .center
        
        labelNode.fontSize = 50
        labelNode.name = "Bomb"
        return labelNode;
    }
