How to show a message when someone join?

[vincentfretin]

You can send your own message when you connect and do anything you want with it.
For example if you start with the nametag example where you have the player-info component. You could do something like this:

const sendJoinMessage = (playerInfo) => {
  const name = playerInfo.nametag;
  const data = { type: "joined", name: name };
  NAF.connection.broadcastDataGuaranteed("chatbox", data);
};

const receiveData = (_, dataType, data) => {
  if (data.type === "joined") {
    console.log(`${data.name} joined`);
  }
};

function onConnect() {
  NAF.connection.subscribeToDataChannel("chatbox", receiveData);
  sendJoinMessage(document.getElementById('rig').components['player-info'].data);
};
