Now that we have animated characters walking around, let’s take it one step further by learning how to interact with other players. The Multiplayer API provides several useful methods to keep track of everyone connected to the session.

Here are the main ones:

• Multiplayer.me – returns information about the current player.
• Multiplayer.players – provides a list of all currently joined players.
• Multiplayer.onPlayerJoined – allows you to react when a new player joins.
• Multiplayer.onPlayerLeft – allows you to react when a player leaves.

Let’s see how to use these APIs in action.

First, we’ll display each character’s name so others can recognize who’s who:

1character.name = Multiplayer.me.userName;
2character.nameVisible = true;

Next, let’s make it more fun by having new players greet everyone already in the session:

1let speechReg = Disposable.empty;
2
3if (!Multiplayer.players.empty) {
4    let greeting = "Hello ";
5    
6    for (let player of Multiplayer.players) {
7        greeting += ", " + player.userName;
8    }
9    
10    character.speech = greeting;
11    speechReg.dispose();
12    
13    speechReg = Time.schedule(5, () => {
14        character.speech = "";
15    });
16}

Finally, let’s make existing players greet newcomers when they join the game:

1Multiplayer.onPlayerJoined(player => {
2    character.speech = "Hello, " + player.userName;
3    speechReg.dispose();
4    
5    speechReg = Time.schedule(5, () => {
6        character.speech = "";
7    });
8});

With these simple additions, your multiplayer world becomes much more interactive, as players can now identify each other and exchange friendly greetings when joining or leaving the session. It’s a small touch that makes the experience feel alive!

Next, we’ll tidy things up by making sure characters are removed when players disconnect, preventing leftover avatars from cluttering the scene.
