Hi everyone!
I’m trying to implement a share screen experience cross-browser through WebSocket and Threejs.
I want when the administrator changes the 3d scene in the admin portal, the 3d scene at the user will also change.
I added an event listener for 3d scene in the admin portal and send data event to the user’s browser through Websocket.
```
// code listen event change in admin site
controls = new OrbitControls(camera, renderer.domElement);
controls.addEventListener('change', function (event) {
render();
// send data to user's browser
emitEvent(event);
});
```
this is data I give when has event change: [https://jsoneditoronline.org/…](https://jsoneditoronline.org/?fbclid=IwAR3v-085vznrzsyiSXhywudqQH3YfseV4O2-B4gDgiKLB8M7Mu9-TgYKeao#left=cloud.33d8c04eb89c40ae920e8dadee70bae3&right=local.taxoqi)
But I can’t apply data events to change the user’s scene follow the scene in the admin portal.
```
// here is code listen event change in user's site
// apply event changed scene
socket.on('changed_scene', (event) => {
console.log(JSON.stringify(event));
let matrix = event.target.object.object.matrix;
// not working
camera.matrixAutoUpdate = false
camera.matrix.set(...matrix);
render();
});
```
I really need help. please help me if you know.
Thank you very much!

Change it to `event.target.object.matrix`
> camera.matrix.set(…matrix)
matrix is a `THREE.Matrix4` instance, and is not iterable. You are supposed to use `matrix.elements `instead. I recommend `camera.matrix.fromArray(matrix.elements)` or `camera.matrix.copy(matrix)` here, so you don’t have to care about the transpose thing.
