mqtt-node

Overview

A simple mqtt (v3) implementation in gdscript.

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!

Usage

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])
    )
