Is JAction a replacement for Unity Coroutines?

Yes, JAction offers a more readable, fluent syntax and better performance through pooling, while providing more robust features like timeouts and per-execution cancellation.

What is task snapshot isolation?

When an execution starts, the current task list is snapshotted. This means you can modify the JAction object for future executions without affecting those already running in parallel.

How does JAction achieve zero-allocation async?

JAction uses an internal object pooling system (JObjectPool) and provides overloads that accept state objects, allowing you to use static lambdas and avoid closure-based allocations.

Why is 'using var' critical when using JAction?

Using the 'using' statement ensures that the JActionExecution object is disposed of correctly, which returns the JAction instance to the pool and prevents memory leaks.

Game Development

Provides a fluent, chainable task system for Unity with zero-allocation async execution and automatic object pooling.

About

JAction is a high-performance task execution framework for Unity developers that simplifies the creation of complex action sequences like timers, loops, and polling conditions. Designed for performance-critical game logic, it utilizes automatic object pooling to eliminate garbage collection overhead and features unique task snapshot isolation. This allows developers to orchestrate intricate gameplay workflows—such as cooldowns, wave spawners, and UI sequences—with a clean, readable API that serves as a powerful alternative to standard coroutines.

Key Features

Zero-allocation async operations using automatic object pooling
Comprehensive timing and loop controls with timeout support
Built-in polling mechanisms like WaitUntil and WaitWhile
Snapshot isolation for safe and independent parallel execution
Fluent, chainable API for composing complex action sequences
2,166 GitHub stars

Use Cases

Managing gameplay systems like cooldown timers and damage-over-time effects
Orchestrating multi-step sequences such as enemy wave spawners and AI routines
Implementing efficient UI transition flows and asynchronous asset loading
