上下滑动以将 ARKit 覆盖移入和移出

如何解决上下滑动以将 ARKit 覆盖移入和移出

我希望能够让用户上下滑动以相应地将对象移近和移近用户的脸部。

我在这里类似地完成放大和缩小：

@objc func handlePitch(withGestureRecognizer recognizer: UIPinchGestureRecognizer) {
    let tapRecognizer = recognizer.location(in: arView)
    let hitTestResults = arView.hitTest(tapRecognizer)
    guard let node = hitTestResults.first?.node else {
        return
    }

    if (recognizer.state == .changed) {
        let pinchScaleX = Float(recognizer.scale) * faceOverlayContent.scale.x
        let pinchScaleY =  Float(recognizer.scale) * faceOverlayContent.scale.y
        let pinchScaleZ =  Float(recognizer.scale) * faceOverlayContent.scale.z

        faceOverlayContent.scale = SCNVector3(x: Float(pinchScaleX),y: Float(pinchScaleY),z: Float(pinchScaleZ))
        recognizer.scale=1
    }
}

我的尝试并将其移入移出：

  @objc func handlePan(_ gestureRecognizer: UIPanGestureRecognizer){
    gestureRecognizer.minimumNumberOftouches = 1

    let results = self.arView.hitTest(gestureRecognizer.location(in: gestureRecognizer.view),types: ARHitTestResult.ResultType.featurePoint)
    guard let result: ARHitTestResult = results.first else {
        return
    }
    
    if (gestureRecognizer.state == .changed) {
        let position = SCNVector3Make(result.worldTransform.columns.3.x,result.worldTransform.columns.3.y,result.worldTransform.columns.3.z)
        faceOverlayContent.position = position
    }
}

当我平移时它根本不会移动对象。
