Object Pooling

The MLAPI provides built-in support for Object Pooling, which allows you to override the default MLAPI destroy and spawn handlers with your own logic.

This allows you to store destroyed network objects in a pool to reuse later. This is useful for often used objects, such as bullets, and can be used to increase the application's overall performance.

See Introduction to Object Pooling to learn more about the importance of pooling objects.


You can register your own spawn handlers. MLAPI will use them in place of default spawn handlers to instantiate and destroy objects.

NetworkSpawnManager.RegisterCustomSpawnHandler(NetworkSpawnManager.GetPrefabHash("myPrefabName"), (position, rotation, disabled) =>
// Called when the MLAPI want's to spawn a Prefab with the name "myPrefabName"


NetworkSpawnManager.RegisterCustomDestroyHandler(NetworkSpawnManager.GetPrefabHash("myPrefabName"), (networkObject) =>
// Called when the MLAPI want's to destroy the given NetworkObject

Registering your own spawn handlers allows you to pool all networked objects on clients as they're destroyed and spawned on your clients.

To pool objects on the server side, don't use Destroy. Use NetworkObject.Despawn first, then manually pool the object.
