An interface that poolable classes can implement to get notified when they’re spawned or despawned.

Need multiple MonoBehaviours to get notified when their prefab instance is spawned or despawned then look at PoolableGroup.


Just implement the interface in the pooled class.

public class MyPooledClass : IPoolable
    public void OnSpawned()
        Debug.Log("I'm alive!");

    public void OnDespawned()
        Debug.Log("Back into the pool I go :(");

// somewhere else
var myInstance = PoolHelper<MyPooledClass>.Spawn();
Debug.Log("I just spawned myInstance");

Debug.Log("I just despawned myInstance");

Will output:

I'm alive!
I just spawned myInstance
Back into the pool I go :(
I just despawned myInstance
