Object Pool Plugin

A lightweight, high-performance, fully replicated object pooling system for Unreal Engine 5.

Reuse actors instead of spawning and destroying them constantly. Ideal for projectiles, effects, pickups, and enemies.

Features

• UObjectPoolComponent for easy pool management
• APooledObject base class with activation/deactivation events
• Configurable pool size and auto-despawn lifespan
• Server-authoritative spawning (RPC supported)
• Full multiplayer replication
• Blueprint Native Events for simple setup
• Improves performance by reducing spawn/destroy overhead
• No dependencies

Installation

1. Create folder Plugins/ObjectPoolPlugin in your project
2. Copy the plugin files from this repo into it
3. Enable the plugin in the Editor
4. Restart Editor

Quick Start

1. Add Object Pool Component to a manager actor (GameMode, Level Blueprint, or dedicated spawner recommended)
2. In the component details, set:
   • Pooled Object Class (any class inheriting from APooledObject)
   • Pool Size
3. Call SpawnPooledObject(FTransform SpawnTransform) to get an actor from the pool
4. When finished with the actor, call Deactivate() on it (or set a lifespan)

Actor Setup

Create your actors by inheriting from PooledObject instead of Actor, then override:

• PoolObjectActivate → Show meshes, enable collision, start effects
• PoolObjectDeactivate → Hide meshes, disable collision, stop effects
