Import class

import { SingleRoom } from 'phaser3-rex-plugins/plugins/firebase-components.js';

Add single-room object
```
var room = new SingleRoom(config);
```

Create instance¶

var room = scene.plugins.get('rexFirebase').add.singleRoom({
    root: '',
    // maxUsers: 0,
    // userID: '',
    // userName: '',
    // broadcast: true,
    // tables: undefined,

});

root : Path of this room.
maxUsers: Maximum users in this list. Set to 0 to have infinity users.
userID : ID of user.
userName : Name of user.
broadcast : Broadcast chat messages.
- true : Enable broadcasting, without storing received (history) messages. Default behavior.
- false : Disable broadcasting.
- A JSON object :
```
{
    history: 0
}
```
  - history : Stored received (history) messages in client side.
    - 0, or false : No history message stored.
    - -1, or true : Infinity history message stored. i.e. store all messages from starting updating.
    - A number larger then 0 : Length of stored history message.
tables : Configuration of tables.
- undefined : No table.
- Array of table-config JSON object for each table.
```
[
    {
        key: tableKey,
        type: '1d'
    },
    {
        ...
    }
]
```
  - key : Unique name of this table.
  - type : Table type.
    - 1, or '1d' : 1d table, indexing by (key0)
    - 2, or '2d' : 2d table, indexing by (key0, key1)
    - 3, or '3d' : 3d table, indexing by (key0, key1, key2)

Join room¶

Set userID and user name.
```
room.setUser(userID, userName);
```
- userID : User ID.
- userName : Display name.
Join room.
```
room.joinRoom();
```

Leave room¶

room.leaveRoom();

Kick user¶

room.kickUser(userID);

User list¶

Get users in room(user list)
```
var users = room.getUsers();
```
- users : Array of user {userID, userName}

Is first user in room(user list)?

var isFirstUser = room.isFirstUser(userID);
// var isFirstUser = room.isFirstUser();  // Current user is first user

Room(user list) is full
```
var isFull = room.isFull();
```
Maximun users setting value
```
var maxUsers = room.maxUsers;
```
Current user is in room(user list)
```
var isInRoom = room.isInRoom();
```

Send message¶

room.broadcast.send(message);

message : A string message, or a JSON data.

Register receive event

room.on('broadcast.receive', function(data){
    // var senderID = data.senderID;
    // var senderName = data.senderName;
    // var message = data.message;
})

Only receive messages after joined room. Previous messages won't be got anymore.

Received messages¶

Received messages will be saved in client side.

var messages = room.broadcast.getHistory();

Clear history messages.
```
room.broadcast.clearHistory();
