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.

Simpleton v1.5.0 & Selectable Scroll v1.6.0 Released: Now with AI Skills Support!

I'm happy to announce that both Simpleton v1.5.0 and Selectable Scroll v1.6.0 are now live on the Asset Store!

🚀 What's New

Both releases add AI Skills — structured documentation that lets AI coding assistants (like Claude) understand and use these assets correctly right out of the box. Just ask your AI assistant to set up dependency injection with Simpleton, or scroll navigation with Selectable Scroll, and it can follow each asset's own best practices automatically.

Selectable Scroll v1.5.0 Released

Selectable Scroll v1.5.0 has been released on the Unity Asset Store.

Asset Store Page:

https://assetstore.unity.com/packages/tools/gui/selectable-scroll-316544

Release Notes (v1.5.0)

• Added elastic bounce-back to the SelectableScrollerTouchController's touch flick scrolling.

• When MovementType is set to Elastic and a flick scrolls past the first or last element, the content now eases back to the clamped position over a configurable elasticDuration instead of staying stretched.

• Added an overscrollDecelerationRate field so the bounce-back kicks in promptly even when decelerationRate is set very low, preventing the content from lingering stretched past the edge for an extended time before settling.

Simpleton v1.4.0 Released: Self-Contained Prefabs, Fast Enter Play Mode Support & More!

I am excited to announce that Simpleton v1.4.0 is now officially available on the Unity Asset Store!

Simpleton is a lightweight, minimalistic Dependency Injection (DI) framework designed for Unity game development. In this update, I’ve focused on improving usability, reducing boilerplate code, and ensuring full compatibility with the latest Unity features.

🚀 What’s New in v1.4.0

1. Self-Contained Prefabs (Zero-Setup Installer)

Creating reusable prefabs with DI is now easier than ever. When the Target Game Objects array on SimpletonInstaller is left empty, it will automatically target and inject into its own GameObject and attached components.

- Benefit: You can simply attach a SimpletonInstaller component to a prefab without any Inspector configuration required. It just works!

2. Safety & Convenience: ExecuteIfPresent Helper

I’ve introduced the ExecuteIfPresent(Action<T> action) method to streamline handling deferred references and optional dependencies.

- Benefit: Safely execute logic only when a service or reference is initialized, eliminating repetitive null check boilerplate code.

3. Full Fast Enter Play Mode Support (Unity 6.6+)

Starting with Unity 6.6, Fast Enter Play Mode (Domain Reloading disabled) is the default setting for new projects. To support instant Play mode transitions without state leaks, Simpleton v1.4.0 automatically resets static fields and reflection caches on SubsystemRegistration.

- Benefit: Seamless performance during Play mode testing with zero state persistence across sessions.

📖 Full Changelog

[1.4.0] - 2026-08

• SimpletonInstaller now injects into its own GameObject when Target Game Objects is left empty. This makes it possible to create self-contained prefabs by simply attaching a SimpletonInstaller, with no inspector setup required.

• Added ExecuteIfPresent(Action<T> action) method to allow safe execution of logic only when a value is present, reducing null-check boilerplate.

• Added support for Fast Enter Play Mode (Domain Reloading disabled) by automatically resetting static fields and reflection caches on SubsystemRegistration.

SelectableScroll v.1.4.0 Released

SelectableScroll v.1.4.0 is now available.
This update focuses on improving control over looping behavior when navigating grid-based UI, enabling more natural cursor movement at the edges of the grid.

Release Notes (1.4.0 – December 2025)

• 1.4.0 - December 2025

  • Added a new function in the SelectableScroll grid to control looping at the first and last elements.

    • When GridWrapAround is enabled, it allows temporarily disconnecting and reconnecting the wrap-around connections.

    • This enables implementing behavior where the cursor can pause temporarily at the start or end of the grid.

  • Updated the Sample07_WrapAround demo scene to include an example demonstrating this new feature.

Overview

In some UI layouts, continuous looping can feel too fast or make it easy to overshoot selections.
With this update, you can give users a sense of reaching the “edge” of the grid while still preserving loop functionality, resulting in more intuitive and controlled navigation.

Closing Notes

If your UI relies on looping navigation, try out the new wrap-around control option.
SelectableScroll will continue to evolve to support smoother and more flexible UI development.

SelectableScroll v1.3.0 Released

 I’ve just released SelectableScroll v1.3.0!

This update addresses an issue where the scroll movement stopped working when Time.timeScale was set to zero.

Previously, the scroll animation during cursor movement relied on Time.deltaTime.
However, since deltaTime becomes zero when the game is paused (Time.timeScale = 0), the menu scrolling would freeze as well.

To fix this, I added a new GetDeltaTime() function that provides a customizable delta time value.
By default, it now uses Time.unscaledDeltaTime, allowing menu scrolling to remain smooth even when the game is paused or slowed down.

What's New

• Added protected virtual float GetDeltaTime()

• Default implementation returns Time.deltaTime

• Can be overridden for custom timing behavior

Compatibility

This update introduces no breaking changes — existing projects using previous versions will continue to work as expected.
