如何在 SceneView SwiftUI 中暂停/播放 animation

Question

I am trying to pause and resume the animation of a 3D scene in SwiftUI, using isPaused but not sure why it doesn't pause or resume the scene's animation. Here is the code:

var scene: SCNScene? {
        let scene = SCNScene(named: "model.dae")
        scene?.rootNode.scale = SCNVector3(0.6, 0.6, 0.6)
        return scene
    }

var body: some View {

     VStack {

          SceneView(
                scene: scene,
                pointOfView: cameraNode,
                options: [.allowsCameraControl, .autoenablesDefaultLighting]
                )


  Button("Pause") {
      scene?.isPaused = false 
    }

  }
}

I tried scene?.rootNode.isPaused but still nothing happened, any help would be great.

Answer 1

I do it like this:

to pause:

sceneView.scene?.rootNode.isPaused = true
sceneView.scene?.isPaused = true
sceneView.isPlaying = false

to un-pause:

sceneView.isPlaying = true
sceneView.scene?.isPaused = false
sceneView.scene?.rootNode.isPaused = false

Hopefully this will work for you.
