Scriptable Singleton

The Scriptable Singleton class is a variant of the Singleton class that allows you to access a single instance of a ScriptableObject from anywhere in your code. This is useful for storing global data that you want to be able to access from anywhere in your game.

How to use it

To get started, create a new class that inherits the ScriptableSingleton class using the following syntax:

[CreateAssetMenu(menuName = "Singleton Objects/Prefab Manager")]
public class PrefabManager : ScriptableSingleton<PrefabManager>
{
}

For this system to work, you must create an instance of your singleton scriptable object in your project’s Resources/Singleton folder. If this folder does not exist, you will need to create it. The CreateAssetMenu attribute is used to add a menu item to the Unity Editor’s Assets/Create menu. This allows you to easily create an instance of your singleton asset.

It’s recommended to have exactly one instance of your singleton asset in your project. If you have more than one, the system will use the first one it finds, which may be unexpected.

Accessing your singleton

Just like the regular Singleton class, you can access the properties of your ScriptableSingleton using the Instance property. For example, if you have a PrefabManager singleton, you can access it like this:

PrefabManager _prefabManager = PrefabManager.Instance;

That’s all there is to it! You can now access your scriptable singleton and any reference it has from anywhere in your code.
