Colyseus SDK for GODOT.

Try the online mode of this demo: https://gsioteam.github.io/ActionGame/

Usage

var client = colyseus.Client.new("ws://localhost:2567")
var promise = client.join_or_create(RoomState, "state_handler")
yield(promise, "completed")
if promise.get_state() == promise.State.Failed:
    print("Failed")
    return
var room: colyseus.Room = promise.get_result()
var state: RoomState = room.get_state()
state.listen('players:add').on(funcref(self, "_on_players_add"))
room.on_state_change.on(funcref(self, "_on_state"))
room.on_message("hello").on(funcref(self, "_on_message"))

Documentation

Totaly the API is same as colyseus.js. There are only two points to note.

Schema

Define a schema class only needs to inherit colyseus.Schema and implement the define_fields method.

class RoomState extends colyseus.Schema:
  static func define_fields():
    return [
      colyseus.Field.new("players", colyseus.MAP, Player),
    ]

Get players by state.players. And the collection classes are defined in godot_colyseus/lib/collections.gd.

Event Listener

Use listen method to observe the change of attrbites. The structure of first argument path is like this path/to/attribue:action. The path part can be empty like :replace, that means listening this node.

Actions:

Action	Description	Arguments
add	A attrbite or element of this schema object is created or added.	_on_add(current: Schema, new_value: any, key: String\int)
remove	A attrbite or element of this schema object is removed.	_on_remove(current: Schema, old_value: any, key: String\int)
replace	A attrbite or element of this schema object is replaced.	_on_replace(current: Schema, new_value: any, key: String\int)
delete	The schema object which at the path is deleted.	_on_deleted(current: Schema)
create	The schema object which at the path is created.	_on_created(current: Schema)
change	The schema object which at the path is changed.	_on_changed(current: Schema)
