Simpleton v1.7.0 Released: Multiple Registrations in Deferred Reference & UniTask Integration!

I am excited to announce that Simpleton v1.7.0 is now officially available on the Unity Asset Store!

Simpleton is a lightweight, minimalistic Dependency Injection (DI) framework designed specifically for Unity game development. In this update, we are expanding the capabilities of `IDeferredReference<T>` by adding support for multiple instance registrations and broadcast notifications, as well as seamless asynchronous operations with UniTask integration.

🚀 What's New in v1.7.0

1. Multiple Registration & Broadcasting in IDeferredReference<T>

`IDeferredReference<T>` is designed to safely handle dependencies that are instantiated and destroyed at runtime (such as dynamic UI popups and spawned game views). In v1.7.0, multiple instances implementing the same interface can now be registered to a single deferred reference simultaneously.

By calling `ExecuteIfPresent(Action<T> action)`, Simpleton iterates and delivers the action to all currently registered instances in their registration order. If no instances are present, it safely skips execution without throwing exceptions or requiring explicit null/collection checks.

• Backward Compatible: The `.Value` property continues to return the most recently registered instance. When an instance is destroyed, `.Value` automatically reverts to the previous instance (or `null` if all are gone).

• Benefit: Perfect for broadcasting game state updates or notifications to multiple spawned views (e.g., world-space HUD indicators, minimap icons, status bars) without the sender needing to track how many views currently exist.

2. UniTask Integration (ExecuteIfPresentAsync)

For projects using UniTask, we have introduced the `DeferredReferenceUniTaskExtensions.ExecuteIfPresentAsync` extension method (available under the `FigCodeFactory.Simpleton.UniTask` assembly).

You can now trigger asynchronous tasks across all registered instances and await their collective completion via `UniTask.WhenAll` with a single line of code:

```csharp

await views.ExecuteIfPresentAsync(async view =>

{

    await view.PlaySpawnAnimationAsync();

});

```

If zero instances are registered, it returns an immediately completed `UniTask`. Simpleton automatically enables this extension when UniTask is installed via the Unity Package Manager (UPM).

• Benefit: Simplifies coordinating asynchronous UI transitions, cutscene triggers, and parallel visual effects across dynamically spawned GameObjects.

3. New Sample Scene & Updated AI Skills

• Sample 15 (15_DeferredReferenceMultipleRegistration): A new sample scene showcasing multiple time display views (SystemTimeDisplay and ElapsedTimeDisplay) dynamically toggled at runtime, receiving broadcast updates from a single presenter.

• Updated AI Skills: The built-in AI Skills (under `AI/Skills/`) have been updated to asset-version 1.7.0, complete with new scenario test coverage (S004) so AI coding assistants (like Claude and Gemini) can reliably adopt multi-registration patterns and UniTask workflows.

• User Guide: The User Guide PDF has been updated with detailed explanations, best practices, and code examples for multi-instance registration and UniTask usage.

📖 Full Changelog

• Added multiple instance registration support to IDeferredReference<T>.

• Added UniTask integration extension ExecuteIfPresentAsync for asynchronous broadcast operations.

• Added new sample scene: 15_DeferredReferenceMultipleRegistration.

• Added documentation for multiple registrations and UniTask integration to the User Guide PDF.

• Updated AI Skills to asset-version 1.7.0 with new benchmark scenario coverage.

Simpleton v1.6.0 Released: Buffered Pub/Sub Messaging & Code-Based Deferred Reference Registration!

 I am excited to announce that Simpleton v1.6.0 is now officially available on the Unity Asset Store!

Simpleton is a lightweight, minimalistic Dependency Injection (DI) framework designed specifically for Unity game development. In this update, we are introducing buffered messaging support for late-subscribing components, as well as code-based registration APIs to make deferred references and unit testing even more flexible.

🚀 What's New in v1.6.0

1. Buffered Pub/Sub Messaging (Replay to Late Subscribers)

We have added buffered Pub/Sub interfaces (IBufferedMessagePublisher<T> / IBufferedMessageSubscriber<T> for Scoped, and IGlobalBufferedMessagePublisher<T> / IGlobalBufferedMessageSubscriber<T> for Global).

Unlike standard Pub/Sub, buffered messaging holds onto the latest published message and immediately delivers it to any subscriber as soon as they subscribe. It also provides a TryGetLatest(out T message) method for synchronous, non-destructive inspection.

• Benefit: Perfect for UI views, HUD elements, or late-spawned game objects that need the current game state (e.g., player score, HP, current game mode) the moment they initialize, without waiting for the next event to be fired. Check out the new 14_BufferedPubSub sample scene included in the package!

2. Code-Based Deferred Reference Registration

You can now register instances into IDeferredReference<T> directly from C# code using ServiceProvider.RegisterToDeferredReference<T>(). The registration returns an IDisposable token, allowing clean and automatic deregistration when the provider or object is disposed.

• Benefit: Greatly simplifies unit testing by making it trivial to inject mock/stub implementations into deferred references programmatically, as well as registering runtime-created objects without relying exclusively on attributes or Inspector references.

3. Updated AI Skills & User Guide

The built-in AI Skills (under AI/Skills/) have been updated to asset-version 1.6.0, allowing AI coding assistants (like Claude) to automatically leverage buffered messaging and new deferred reference APIs following best practices. In addition, a dedicated section explaining buffered Pub/Sub has been added to the User Guide PDF.

📖 Full Changelog

[1.6.0] - 2026-09

• Added Buffered Pub/Sub interfaces and implementations (IBufferedMessagePublisher<T> / IBufferedMessageSubscriber<T> and global variants).

• Added TryGetLatest(out T message) to buffered message subscribers for immediate state inspection.

• Added ServiceProvider.RegisterToDeferredReference<T> for code-based deferred reference registration.

• Exposed SimpletonContainer.GetDefaultAutoRegisterGenericImplementationType as a static method.

• Added new sample scene: 14_BufferedPubSub.

• Added a dedicated Buffered Pub/Sub chapter to the User Guide PDF.

• Updated AI Skills to asset-version 1.6.0 with full scenario coverage.
