object-pooling

What problem does it solve?

Instantiating and destroying objects in Unity creates garbage and GC spikes. Object pooling reuses objects to reduce allocations and GC pressure.

Core Features & Use Cases

• Unity Built-In ObjectPool<T> (2021+) usage pattern with create/get/release hooks
• Warm-Up: pre-spawn objects during loading to avoid stutters
• Return-to-Pool Lifecycle: reset state when returned to pool
• When to Pool: projectile, particle, enemy, and UI element lifecycles
• Pool Sizing: start sizes, monitor runtime allocations, per-level tuning
• Generic Pool Manager: manage pools for multiple prefabs
• Cached WaitForSeconds: reuse WaitForSeconds to avoid allocations

Quick Start

Start by creating a pool for frequently instantiated objects (e.g., bullets) and reuse them to avoid runtime allocations.
