LANServerBroadcast
Nodes for broadcasting and receiving LAN games in the Godot game engine.
These allow you to setup a dead simple LAN only server browser for multiplayer games.
Setup for the host
Add the ServerAdvertiser
node to your game Lobby scene (but only for the host if it's peer to peer), this will broadcast the fact that you are hosting on this IP.
You can customize the serverInfo
being broadcast from the lobby by setting entries in the serverInfo
dictionary on this node.
advertiser.serverInfo["name"] = "A great lobby"
advertiser.serverInfo["port"] = 3333 # This is important so the client knows what port to connect on
advertiser.serverInfo["max_players"] = 10
advertiser.serverInfo["cur_players"] = 3
You can change this info at will, and the new changes will be broadcast out at the next interval.
The broadcast interval can be changed on the ServerAdvertiser
node via the exposed property: broadcast_interval
(default is 1 second)
Setup for the client
For your server browser, Add the ServerListener
node to your Server Browser scene, and wire up the two signals: new_server
, remove_server
You should add the server to your server browser UI when you receive new_server
.
You can use the info that the server provided in it's serverInfo
to populate the UI in your server browser.
On the client this is represented as an object who's properties are the fields the server specified.
In adition to what ever you added via advertiser.serverInfo[]
the ServerListener
node also adds in the server's IP: serverInfo.ip
From the example above, access the fields as such:
func _on_ServerListener_new_server(serverInfo):
serverInfo.ip
serverInfo.name
serverInfo.port
serverInfo.max_players
serverInfo.cur_players
To connect to a game, you just grab the IP and Port (if it's not hard coded for your game) from the serverInfo, and then perform a normal connection how ever you like.
Lastly, when a server goes offline, you must remove it from the UI. You do this when you receive a remove_server
signal, this is emitted when a server has not been seen for a period of time, which the server browser can specify on the ServerListener
node via the exposed property: server_cleanup_threshold
Nodes for broadcasting and receiving LAN games.
These allow you to setup a dead simple LAN only server browser for multiplayer games.
Simply add the ServerAdvertiser node to your server's scene, and the ServerListener node to your server browser, and wire up a few signals, and you're good to go!
