SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill addresses subtle but critical bugs in Unity's asynchronous programming models (coroutines and Awaitables) that often lead to crashes, memory leaks, and unpredictable behavior in production.

Core Features & Use Cases

  • Correctness Patterns: Identifies and provides solutions for common pitfalls like double-awaiting, missing cancellation tokens, thread context violations, and coroutine error swallowing.
  • Resource Management: Guides on proper handling of Addressables assets to prevent leaks.
  • Use Case: Prevent your game from crashing due to unhandled exceptions in async methods or memory leaks from improperly released Addressables assets by applying these proven patterns.

Quick Start

Show me the correct pattern for using Awaitable.WaitForSecondsAsync with a destroyCancellationToken.

FAQPage Schema
How do I prevent memory leaks when loading Addressables in Unity async methods?

Prevent Addressables memory leaks by applying correct async patterns that ensure proper resource release. This Skill guides proper handling of Addressables assets to avoid leaks from improperly released references in Awaitable and coroutine workflows.

Why does my Unity coroutine swallow exceptions and crash the game?

Unity coroutines swallow exceptions due to missing error handling patterns. This Skill identifies coroutine error swallowing pitfalls and provides solutions to prevent unhandled exceptions from crashing your production game.

What is the correct pattern for using Awaitable.WaitForSecondsAsync with a destroyCancellationToken?

The correct pattern for Awaitable.WaitForSecondsAsync involves properly passing the destroyCancellationToken to enable automatic cancellation. This Skill demonstrates how to implement this correctly to prevent async operations from causing runtime errors.

Can I use C# Task Parallel Library concepts with Unity's Awaitable API?

Yes, you can use C# Task Parallel Library concepts with Unity's Awaitable API by adapting them for the Unity environment. This Skill provides patterns that correctly manage thread context after background operations using adapted TPL concepts.

What causes thread context violations after Unity background operations?

Thread context violations occur when Unity async methods fail to properly return to the main thread after background operations. This Skill addresses thread context management to prevent unpredictable behavior and crashes in your asynchronous programming.
