Instantiate() and Destroy() can be expensive calls; it is often more performant to recycle GameObjects using an object pool pattern.
Our pools focus on components and the scene hierarchy. With a scene hierarchy like this:
Pool (has ParticlePool named "Explosion")
Pooled object (has ParticleSystem)
Pooled object (has ParticleSystem)
It's easy to find and recycle those particles:
PoolManager.Get<ParticlePool>("Explosion").GetNextAt(Vector3.zero);
- The pool will move a particle system to the requested location.
- By default, the particles will play immediately.
- By default, new particle systems will be spawned when the pool is empty.
- Finished particles will be reclaimed automatically.
Pool structure is managed at runtime, using the scene hierarchy.
- PoolManager
- Static class to easily find and use pools.
- ParticlePool
- Pool to manage ParticleSystem components.
- TransformPool
- Every GameObject has a transform, making this pool extremely versatile.
It's easy to manage other components, including your own custom components, by creating a new class inheriting from ComponentPool<T>.
