🚦 SignalBus

SignalBus is a Godot editor plugin that enables the creation of global signals! Global signals may be emitted from and/or connected to any script in your project.

✨ Features

SignalBus (Autoload)

A core singleton script that manages the addition, modification, removal, and emitting of global signals. After registering a global signal, it can be emitted or connected to from any script in the project.

🛠 When to Use

✅ Use SignalBus when

• Several unrelated classes must define and emit the same signal.
• You are dealing with complex Node or SceneTree hierarchies.
• You need global events that can be accessed by any object.

💻 Quick Start Example

1. After enabling the plugin, select the SignalBus tab in Project Settings.
2. Input the string game_over in the Add New Global Signal field.
3. Press Enter or select the + Add button.
4. Connect and emit the signal from anywhere :)

# Emitting a signal
SignalBus.emit_signal("game_over")

# Listening to a signal
SignalBus.connect("game_over", Callable(self, "_on_game_over"))

func _on_game_over():
    print("Game over!")

🛑 Disclaimers

SignalBus does not replace Godot’s built-in signal system. Most implementations do not require global signals.

Although the plugin make's use of Gut for testing purposes, it is not a mandatory dependency and will not impact SignalBus' functionatliy if it is not included.
