ios - 如何将实体移回其初始位置

Question

在对球施加线性脉冲和扭矩后，我试图将球移回其初始位置。

从 Reality Composer 加载场景时，我将球的初始变换存储在此处

Experience.loadTestSphereAsync { (result) in
            switch result {
            case .success(let anchor):
                anchor.generateCollisionShapes(recursive: true)
                self.testSphereAnchor = anchor
                self.ball?.physicsBody?.mode = .static
                self.arView.scene.anchors.append(self.testSphereAnchor)
                self.ballStartTransform = self.testSphereAnchor.ball?.transform
                self.targetStartTransform = self.testSphereAnchor.target?.transform
                self.addTapGestures()
            case .failure(let error):
                fatalError(error.localizedDescription)
            }
        }

要将球移回其原始位置，我正在这样做

func didPressRestartButton() {
        ball?.clearForcesAndTorques()
        ball?.physicsBody?.mode = .static
        ball?.move(to: ballStartTransform!, relativeTo: nil, duration: 0.3)
    }

球并没有回到原来的位置，而是冻结在它所在的位置。

将physicsBody模式改为.kinematic
