For cross-platform compatibility its just working with websocket. There are no plans to support tcp/udp!

Installation

1. Copy addons/mqtt-node to your godot project
2. Done! You can use the MqttNode component now!

Example (Using just code)

extends Node2D

@onready var mqtt := MqttNode.new()

func _ready() -> void:
	mqtt.broker = 'wss://broker.hivemq.com:8884/mqtt'
	mqtt.auto_connect = true

	mqtt.connecting.connect(func():
		print("Connecting...")
	)
	mqtt.connecting_failed.connect(func():
		print("Connecting failed!")
	)
	mqtt.connected.connect(func():
		print("Connected!")
		mqtt.subscribe("test/#")
	)
	mqtt.disconnected.connect(func():
		print("Disonnected!")

	mqtt.message.connect(func(topic, msg):
		print("Message (%s): %s" % [topic, msg])
