AnkleBreaker FishNet Core — Unity Multiplayer Networking Layer

Core FishNet networking abstractions and utilities for multiplayer Unity games. AnkleBreakerNetworkBehaviour with automatic event lifecycle, ownership tracking, SyncVar reset, and a searchable prefab selector. Built on Fish-Networking. UPM-ready. Free and open source by AnkleBreaker Studio.

Features

• AnkleBreakerNetworkBehaviour: Abstract base class extending NetworkBehaviour with automatic event handler registration/unregistration on network start/stop, SyncVar-based behaviour reset mechanism, ownership change tracking with server and client callbacks for player connect/disconnect, IsLocallyReady state tracking, and S_OnClientOwnerIsReady server callback when the owning client is ready.

• AKSinglePrefabs: Custom SinglePrefabObjects wrapper with null entry cleanup and custom editor.

• NetPrefabsSelectorWindow: Searchable EditorWindow for selecting network prefabs with multi-select support.

• Extension Methods: NetworkConnection.GetPlayerObjectId() / GetPlayerObject() for quick access to a connection's player object, int.TryGetNetworkObjectFromObjectId() to resolve ObjectId to NetworkObject (client or server), int.L_IsLocalPlayerNobId() to check if an ObjectId belongs to the local player, and SinglePrefabObjects.LookupSpawnablePrefab(name) to find a prefab by name in a prefab collection.
