I am currently working on a project that upon completion pops up a UI and removes xrweb to essentially turn the camera off and AR scene. I now need to add in reset functionality that will then turn the camera and scene back on, so I am adding xrweb back into the scene. It was working a few days ago but now is causing some bugs and headaches. Is there any other way to essentially turn on and off the camera and AR scene? I would normally just refresh the page to restart it but the client doesn’t want the loading screen to come back up. ---

Hey Declan! What issues are you running into with `xrweb`? You might try using `XR8.pause()` and `XR8.resume()` and covering up the paused camera feed with some 2D UI. > **[XR8.pause() | 8th Wall](https://www.8thwall.com/docs/api/xr8/pause/)** > > XR8.pause() > **[XR8.resume() | 8th Wall](https://www.8thwall.com/docs/api/xr8/resume/)** > > XR8.resume() ---

@Evan that seems like it will be a much better solution than what I am doing now. The project I am doing is a self hosted project being developed on VS Code with React and TypeScript. Do you know what I need to import to be able to use XR8 properly? ---

@Declan_Johnson `XR8` is automatically added when the 8th Wall library loads (from the [apps.8thwall.com](http://apps.8thwall.com)… script tag). Usually good to guard your code to make sure it’s on the window before you try to access. Example ```auto const onxrloaded = () => { // Do XR8 stuff here } // Wait until the XR javascript has loaded before making XR calls. window.XR8 ? onxrloaded() : window.addEventListener('xrloaded', onxrloaded) ``` If you already initialized the `xrweb` component in your AFrame scene then XR8 is already on the window - but never hurts to code defensively 🙂 ---

Regarding the type declaration, I would just use a generic type: ```auto declare let XR8: any ``` For reference: [A-Frame: React - Multiple Scenes | 8th Wall Playground | 8th Wall](https://www.8thwall.com/playground/multi-scene/code/lib/aframe-components.tsx#L6) ---

So currently i am getting back a message that says “[XR] Pause cannot be called at this time.” ---

Never mind, I got it working. This was a problem not attached to this code, thank you! ---

how did you fix the “[XR] Pause cannot be called at this time.” ? i keep getting it after the xrloaded event and even after i check the XR8.isInitialized() ---

For me this was occurring because the scene was re-rendering right before I called the XR8.pause() function. I am working in react and there was a small call that was breaking things. Not sure if that helps or not, but that is what was happening to me.
