Scriptable Singletons

Easy to use singleton implementation for ScriptableObjects in Unity.

Usage

To make your ScriptableObject a singleton, place your asset instance in a Resoures directory.

Then, make your ScrptableObject class inherit from ScriptableSingleton and add the AssetPathAttribute with the path to your asset relative to the Resources folder.

Example

Let's say that you need to access a scriptableObject called MyGameSettings as a singleton.

public class MyGameSettings : ScriptableObject
{
    // ...
}

Make sure only one asset for that object exists and place it in a valid Resources folder (e.g. Assets/Resources/myGameSettingsAsset.asset).

Then, make a few changes to the class definition, as follows:

[AssetPath("myGameSettingsAsset")]
public class MyGameSettings : ScriptableSingleton<MyGameSettings>
{
    // ...
}

Note: if your asset is located in a subfolder within the Resources folder, the path specified in the AssetPath attribute should match with it. For example: an asset in Assets/Resources/Foo/bar.asset should have an attribute [AssetPath("Foo/bar")].

All set! You can access your asset instance with the Instance property.

MyGameSettings.Instance.DoSomething();
