FishNetAddressable

The package itself is mainly for providing FishNet Networking a prefab collection that could be spawn on the network.

Very easy to setup and remove your headache from having to figure out Missing prefab id XXXX error

Type safe and return correct component you want which eliminate the need of GetComponent

Zero use of ambiguous and error prone of using string as a key Use GUID directly from Unity instead

Installing

The package can be easily installed via Unity package manager

https://github.com/SackMaggie/FishNetAddressable.git

1. Open Unity Package Manager Window -> Package Manager
2. Add new package using plus icon on the top left
3. Select Add package from Git URL...
4. Enter the git path above

Sample

You could clone the sample project on this repo

https://github.com/SackMaggie/FishNetAddressableSample

Setup

A quick setup is located at Tools/Fish-Networking/Addressable/Setup
To setup correctly open your scene and select your fishnet NetworkManager gameobject, then click the Setup from the menu
A new prefab handler will be create and assign to your SpawnablePrefabs, Scene handler for addressable will also be added too

Usecase

So you want to instantiate a networked adressable prefab object with a simple class in it ?

//Your typical NetworkBehaviour class
public class AmazingCube : NetworkBehaviour
{
    public override void OnStartNetwork()
    {
        base.OnStartNetwork();
        Debug.Log($"I'm on networked IsClient={IsClientStarted} IsServer={IsServerStarted}");
    }
}

Now your got your class and make a prefab ready to use on the network

// Simple but error prone use-case of addressable
AsyncOperationHandle<GameObject> asyncOperationHandle = Addressables.InstantiateAsync("Prefabs/AmazingCube.prefab"); // what if path/key/name get changed? -> ERROR
GameObject yourGameObject = await asyncOperationHandle.Task;
ServerManager.Spawn(yourGameObject);
AmazingCube amazingCube = yourGameObject.GetComponent<AmazingCube>();
// You will have to use GetComponent here and that's a prone to error since there's no promise that object will contain your AmazingCube class
// Do stuff

My prefered way

public AmazingCubeAssetRef amazingCubeAssetRef; // declared somewhere in your project just like a reference

// A more safer loader
AsyncOperationHandle<AmazingCube> asyncOperationHandle = amazingCubeAssetRef.SpawnAddressableAsync(); // path/key/name change doesn't affect this at all
AmazingCube amazingCube = asyncOperationHandle.Task; // You get your class right away ready to use and have editor validation for correct type internally
// Do stuff

Notice AmazingCubeAssetRef class?? that is another class that will have to be declared somewhere, Normally I'd just put it in the same file. This class will provide us with a GUID based reference just like what you did when reference other stuff through out the project

[Serializable]
public class AmazingCubeAssetRef : NetworkedComponentReference<AmazingCube>
{
    public AmazingCubeAssetRef(string guid) : base(guid)
    {
    }
}
