Question

我的光不跟着我的相机。

在将摄像机添加到场景之前，我已经将灯光添加为摄像机的childNode，但这仍然不能解决问题。

    override func viewDidLoad()
    {
        super.viewDidLoad()

        let scene = SCNScene()

        let shipScene = SCNScene(named: "merchant.scn")

        guard let shipNode = shipScene?.rootNode.childNode(withName: "merchant", recursively: true)
        else
        {
            fatalError("ShipModel is not found!")
        }

        shipNode.position = SCNVector3(x:0, y:0, z:0)

        scene.rootNode.addChildNode(shipNode)


        let lightNode = SCNNode()
        lightNode.light = SCNLight()
        lightNode.light?.type = .omni
        lightNode.position = SCNVector3(x:0, y:2, z:10)

        let cameraNode = SCNNode()
        cameraNode.camera = SCNCamera()
        cameraNode.position = SCNVector3(x:0, y:1, z:8)

        cameraNode.addChildNode(lightNode)

        scene.rootNode.addChildNode(cameraNode)


        let sceneView = self.view as! SCNView
        sceneView.scene = scene

        sceneView.showsStatistics = true
        sceneView.backgroundColor = UIColor.gray
        sceneView.allowsCameraControl = true

    }

无论照相机的位置如何，灯光仍然仅照亮模型的最前面。

完美。唯一缺少的行如下。

    double millisstart = datestart.getTime();
    double millisend = dateend.getTime();
    double millistoday = datetoday.getTime();
    double percent = (((millistoday - millisstart) / (millisend - millisstart)) * 100);
    percentAsString = Double.toString(percent);

    txt5.setText(percentAsString);

相机无法移动灯光-SceneKit
