HKH Object Pooling

Boost Performance. Slash Spawns. Game On.

Say goodbye to the overhead of constant Actor spawning and destruction! The Object Pool Plugin is a high-performance, production-ready solution for Unreal Engine developers who need fast, efficient, and scalable Actor reuse in gameplay.

🧠 What It Does:

The Object Pool Plugin introduces a drop-in system that recycles Actors, Pawns, Characters, and Projectiles instead of spawning new ones every time. This drastically improves runtime performance — reducing memory churn, frame spikes, and garbage collection stalls.

💡 Key Features:

• Blueprint & C++ Ready — Easy to use in Blueprints with fully exposed functions, or plug into C++ with granular control.

• Multi-Type Pools — Includes separate components for Actors, Pawns, Characters, and a powerful Shared Pool for mixed types.

• Custom Events — Supports OnPoolBeginPlay and OnPoolEndPlay for seamless behavior resetting.

• Auto Initialization & Deferred Spawning — Spawn on demand, auto-load on game start, or use advanced manual control.

• Projectile Optimization — Includes custom projectile movement & spline support, bypassing Unreal’s default limitations.

• Niagara Compatible — Built-in support for CPU-based pooling with Niagara FX via Force Solo mode.

🎮 Ideal Use Cases:

• Bullet hell shooters

• RPGs with frequent NPC spawning

• Tower defense games

• Action games with repeated VFX or destructibles

• VR & mobile games needing tight performance budgets

⚠️ Pro Tips:

• Never add a Pool Component to a class it spawns. That causes infinite loops!

• Combine with Niagara’s “Force Solo” for FX pooling.

🧩 Fully Modular. Production-Ready.

Designed with real-world performance in mind, this plugin is already battle-tested in commercial projects. It’s plug-and-play, version-compatible, and easy to drop into any Unreal Engine project using 5.x.

🎯 Why Choose This Over DIY Solutions?

• Saves hundreds of hours of manual pooling setup.

• Provides fully maintained C++ backend with exposed Blueprint logic.

• Includes full support for multiple actor types, custom events, and advanced memory handling.

🛒 Ready to scale your gameplay without sacrificing performance?

Grab the Object Pool Plugin now and supercharge your spawning pipeline — one pooled Actor at a time.
