WebSocket.connect

Opens a WebSocket connection to a server and gives back a socket you can send and receive on.

WebSocket.connect(url: string): WebSocket

This is a WebSocket client only - you can’t host a server with it.

Most commonly used to do things the Seliware sandbox can’t do on its own. Your script can’t open a browser window or touch the rest of the computer, but a small program running on the same machine can. The script talks to that program over a WebSocket and lets it do the work - for example, connect to a local server and send it a message every time the player picks up an item, so the local program opens a browser window.

​

Parameters

Parameter	Type	Description
url	string	The server URL. Starts with ws:// or wss://.

Returns

A WebSocket socket object with this surface:

Member	Kind	Description
Send(message: string, is_binary: boolean?)	method	Sends data to the server. is_binary is optional and defaults to false.
Close()	method	Closes the connection.
OnMessage	event	Fires when the server sends a message. The handler gets the message string.
OnClose	event	Fires when the connection closes.

Example

Example 1
