This commit is a huge refactor of the websocket module. The module is really old, and some design choices had to be re-evaluated. The WebSocketClient and WebSocketServer classes are now gone, and WebSocketPeer can act as either client or server. The WebSocketMultiplayerPeer class is no longer abstract, and implements the Multiplayer API on top of the lower level WebSocketPeer. WebSocketPeer is now a "raw" peer, like StreamPeerTCP and StreamPeerTLS, so it emits no signal, and just needs polling to update its internal state. To use it as a client, simply call WebSocketPeer.coonect_to_url, then frequently poll the peer until STATE_OPEN is reached and then you can write or read from it, or STATE_CLOSED and then you can check the disconnect code and reason). To implement a server instead, a TCPServer must be created, and the accepted connections needs to be provided to WebSocketPeer.accept_stream (which will perform the HTTP handshake). A full example of a WebSocketServer using TLS will be provided in the demo repository.

Closes this [MultiplayerPeer], resetting the state to [constant MultiplayerPeer.CONNECTION_CONNECTED].
|
|
[b]Note:[/b] To make sure remote peers receive a clean close prefer disconnecting clients via [method disconnect_peer].

Starts a new multiplayer client connecting to the given [param url]. If [param verify_tls] is [code]false[/code] certificate validation will be disabled. If specified, the [param tls_certificate] will be used to verify the TLS host.
|
|
[b]Note[/b]: It is recommended to specify the scheme part of the URL, i.e. the [param url] should start with either [code]ws://[/code] or [code]wss://[/code].
