Send and receive data

Send

WSNET provides several functions to send data to the other players.

All send functions accept these 3 arguments:

msg_id - The message ID. You will use this to identify the kind of message received from a player.

player_id - The ID of the player which to send the message (use 255 to send to all lobby players).

data - Data to send (string/number/array/buffer/etc).

For example, if you want to send a chat message to a player.

net_send_string(0, 12, "Hello world!");

// 0 is defined by you to understand the kind of data, in this case a 'chat message'.

The full list of the available functions:

• net_send() - Buffer
• net_send_string() - String
• net_send_string_array() - Array of strings
• net_send_number() - Number
• net_send_number_array() - Array of numbers
• net_send_byte() - Byte
• net_send_byte_array() - Array of bytes
• net_send_array() - Array of numbers/strings/booleans/int64
• net_send_list() - List of numbers/strings/booleans/int64
• net_send_map() - Map of numbers/strings/booleans/int64

Receive

Listen for incoming messages:

net_on(msg_id, callback);

This will register a callback function for the specific message ID, that will be executed every time the player receives a message.

Example:

function on_message(player_id, message) {

show_debug_message(string(player_id) + " sent a message: " + message);

};

net_on(0, on_message);

// This will register the callback for all the messages with ID 0
