In my app, I have a SKVideoNode created from an AVPlayer(:URL) inside 3D Space using SCNNode objects and SCNGeometry objects. I use ARKit .ImageTracking to determine when a specific image is found, and play a video from there. All is good and dandy, except that the player determines to play on its own time, every time the AVPlayer comes into sight; however, it could be whenever the ARImageAnchor the SCNNode is attached to comes into sight. Either way, the AVPlayer is playing every time the node comes into sight of the camera lens. I use

override func observeValue(forKeyPath keyPath: String?, of object: Any?, change: [NSKeyValueChangeKey : Any]?, context: UnsafeMutableRawPointer?) {

    if(keyPath == "rate") {

        print((object as! AVPlayer).rate)

    }

}

to print out the rate, and it is 1, however, it was 0.

I printed out some sort of print function print("Play") for all of my functions utilizing player.pause() or player.play() and none of them are called whenever the rate is changed above. How can I find the source of what is changing the rate of my player?

I checked the original rootnode, self.sceneview.scene.rootNode.childNodes to make sure I am not creating extra VideoNodes/SCNNodes/AVPlayers, etc, and it seems that there is only 1.

Any ideas on why the SKVideoNode/AVPlayer is playing as the SCNNode comes into sight of the camera using ARKit? Thanks in advance!

Edit1:

Made a workaround, to determine ONLY when a user clicked on this node

let tap = UITapGestureRecognizer(target: self, action: #selector(self!.tapGesture))

tap.delegate = self!

tap.name = "MyTap"

self!.sceneView.addGestureRecognizer(tap)

and then inside of this next function, I put

@objc func tapGesture(_ gesture:UITapGestureRecognizer) {

    let tappedNodes = self.sceneView.hitTest(gesture.location(in: gesture.view), options: [SCNHitTestOption.searchMode: 1])



    if !tappedNodes.isEmpty {

        for nodes in tappedNodes {

            if nodes.node == videoPlayer3D {

                videoPlayer3D.tappedVideoPlayer = true

                videoPlayer3D.playOrPause()

                break

            }

        }

    }

}



override func observeValue(forKeyPath keyPath: String?, of object: Any?, change: [NSKeyValueChangeKey : Any]?, context: UnsafeMutableRawPointer?) {

    if(keyPath == "rate") {

        print((object as! AVPlayer).rate)

        if(!self.tappedVideoPlayer) {

            self.player.pause() //HERE

        }

    }

}

where videoPlayer3D is the SCNNode that contains the SKVideoNode.

However, I get the error com.apple.scenekit.scnview-renderer (17): EXC_BAD_ACCESS (code=2, address=0x16d8f7ad0) on the section labeled "HERE" above. It seems that the renderer of the sceneview is attempting to alter my video node in the render function, although, I don't even use the renderer(updateAtTime:) function, I only use

func renderer(_ renderer: SCNSceneRenderer, didAdd node: SCNNode, for anchor: ARAnchor) {



    guard let imageAnchor = anchor as? ARImageAnchor else { return }



    createVideoNode(imageAnchor)



}

to determine when I see an image, i.e., imageTracking and I create the node. Any tips?

Thought 1

The error is presented stating that some method is being called from an SCNView object for the method renderer (that's what I'm understanding from the error), but I don't have the node specifically called. I think maybe a default action, as the node is coming to view, is being called, however, I'm not 100% sure on how to access it or determine which method. The objects I'm using are not SCNView objects, and I don't believe they inherit from SCNView objects (look at the 1st paragraph to see the variables used). Just looking to remove the "action" of the node playing every time it is in view.
