JObjectPool - Thread-Safe Object Pooling

Thread-safe, lock-free generic object pooling for Unity using CAS operations. Works with job system and async operations.

When to Use

• Frequently instantiated objects (bullets, enemies, effects)
• Reducing GC during gameplay
• Multi-threaded object reuse (safe from any thread)
• High-frequency object lifecycle operations

Core API

Constructor

new JObjectPool<T>(
    int maxSize = 64,           // Maximum pooled objects (excess discarded)
    Action<T> onRent = null,    // Called when renting (for initialization)
    Action<T> onReturn = null   // Called when returning (for cleanup)
)

Note: T must be a reference type with a parameterless constructor (where T : class, new()).

Methods

• .Rent() - Get object from pool or create new
• .Return(T obj) - Return object to pool (null values ignored)
• .Clear() - Remove all pooled objects
• .Prewarm(int count) - Pre-allocate objects (won't exceed maxSize)
• .Count - Current available count (approximate, thread-safe)
