Work in progress. Supports A-Frame 0.9.2.

Check out the successor to this component, the A-Frame Firebase Component.

A component to send and consume entity data over WebSockets for simple multiuser A-Frame.

The provided server simply relays all broadcasted data through WebSockets to the rest of the clients.

When the broadcast component is attached to an entity, it will emit all specified component data, the entity ID, and the parent's ID to the WebSocket server once every 10ms (will be adjustable later).

When another client receives that data, it uses it to create an element with the ID if it doesn't exist, and then sync the component data to the entity with setAttribute.

This is primarily used for simply seeing other users walk and look around in the same scene. It probably would not work well with game logic or physics. Needs more experimenting.


Property Description Default Value
send List of comma-delimited component names to broadcast position, rotation
url WebSocket server URL http://localhost:12000
interval Time in ms between sending updates 10



There is a simple Node server in server/. It's about 10 LOC.

Running the example

From /server directory:

npm install
node index.js

From the / directory:

npm install
npm run dev

The WebSocket server will default to PORT 12000.

If you are serving the client over HTTPS, you will need SSL on your webserver. I just serve the client over HTTP and avoid that need.

Browser Installation

Install and use by directly including the browser files:

  <title>My A-Frame Scene</title>
  <script src=""></script>
  <script src=""></script>

  <a-scene broadcast="url: http://localhost:12000">
    <a-entity broadcast="send: geometry, material, position, rotation"
              camera look-controls wasd-controls
              geometry="primitive: box"
              material="color: #222"
              position="0 1.8 5"></a-entity>

NPM Installation

Install via NPM:

npm install aframe-broadcast-component

Then register and use.

You can’t perform that action at this time.
