EventBus

Package: com.amanotes.eventbus v1.0.2
Unity: 2022.3+
Namespace: Amanotes.Orchestra
Dependencies: com.amanotes.extensions 1.0.2

Lightweight type-safe event bus for Unity. Supports global and source-scoped dispatchers, pooled event args, and UI component bindings.

Quick Start

// Type-based (recommended)
KEventBus.AddListener<PlayerDiedEvent>(OnPlayerDied);
KEventBus.Dispatch(new PlayerDiedEvent { lives = 0 });
KEventBus.RemoveListener<PlayerDiedEvent>(OnPlayerDied);

void OnPlayerDied(KEventArgs args)
{
    var data = args.GetData<PlayerDiedEvent>();
}

// Source-scoped
var dispatcher = KEventBus.Get(mySource, autoNew: true);
dispatcher.AddListener<ScoreChangedEvent>(OnScoreChanged);
dispatcher.Dispatch(new ScoreChangedEvent { score = 100 });

Key Types

• KEventBus — static global dispatcher with type-based and string-based APIs
• KEventArgs — event payload wrapper with GetData<T>()
• IDispatcher — type-safe listener interface
• IEventDispatcher — string-based listener interface (legacy)
• KEventBindingBase — MonoBehaviour base for UI event bindings
• KEventButton, KEventSlider, KEventToggle, KEventDropdown, KEventInputField, KEventScrollRect — ready-made UI bindings

Installing in your project

Add to your Packages/manifest.json:

{
  "dependencies": {
    "com.amanotes.eventbus": "1.0.2",
    "com.amanotes.extensions": "1.0.2"
  },
  "scopedRegistries": [
    {
      "name": "npmjs",
      "url": "https://registry.npmjs.org/",
      "scopes": [
        "com.amanotes"
      ]
    }
  ]
}

Then open Unity — the Package Manager will resolve and download all packages automatically.
