class. with a create method that returns a new instance of type T. That’s it, now we can create a Factory that implements this IFactory interface. This should cover most use cases and if not it should not be hard to write a factory that fits your needs. Even if you're well into your project, an object pooling implementation will be very easy to implement (no annoying compiler errors or dependencies), and will … /// Simple pooling for Unity. We gave object pooling as an example of the intersection between good gameplay and good code design in the introduction to optimized scripting methods. This avoids the excessive instantiations, and prevents unnecessary memory allocations. For example, if you initialize a pool of 100 bullets but only ever have 10 on the screen at a time, you have 90 allocated GameObjects that are sitting idle. If you've read the previous parts of this series, you know how important it is to avoid heap deallocations in your C# code in Unity. Now let’s make T of Pool implement IResettable like so. Object pooling Unity C# Example. Object Pooling in unity3d Implementation – step by step guide Download the unity package of the below example here – ObjectPoolingDemo. Thanks for the implementation, learned quite a bit through reading your code. In the Inspector, click the Add Component button, and select New C# Script. Object Pool is one of the common technique of optimizing game performance, and today I’ll show you my object pool implementation. 110 The Class we are using to serialize 110 Creating a Server 110 The Client 112 Chapter 23: Object Pooling 114 Examples 114 Object Pool 114 Simple object pool 116 All the code we have written can be found on GitHub as a Unity3D package for the package manager at LiamEderzeel/Pool. I have an Asteroids clone I'm working on and I want to see if my object pooling is written correctly. The instance is immediately made inactive so that pooled GameObjects aren’t being updated or displayed in the scene, and is then added to the pool. As you can see, we’ve created a GameObejct called Pool which contains a set of objects to recycle. It is a good practice and design pattern to keep in mind to help relieve the processing power of the CPU to handle … Object Pooling gave us 3x more FPS than before (from 40 to 120). Object pooling aims to alleviate the performance hit of instantiating/destroying many objects by activating/deactivating the objects instead, reusing objects when needed. An object pool is a design pattern where a set of initialized objects is kept ready for use. A generic object pool could provide various systems in this game (audio, particles, character + projectile spawns) with consistent object pooling functionality. Finally, AllocateInstance is where the actual instance of the prefab is instantiated. Okay we’re almost there we still need an interface for the pool members to enforce them to have a reset method that restores a pool member to its initial state when we release a member back to the pool. using UnityEngine; using System.Collections.Generic; public class ObjectPool { private GameObject prefab; private List pool; public ObjectPool(GameObject prefab, int initialSize) { this.prefab = prefab; this.pool = new List(); for (int i = 0; i < initialSize; i++) { AllocateInstance(); } } public GameObject GetInstance() { if (pool.Count == 0) { AllocateInstance(); } int … When discussing performance optimization of Unity games, be it 2D or 3D, object pooling is a commonly referred to technique to gain significant improvements.
