Simple & Lightweight solution for managing configuration assets in Unity projects

1. Install Editor Coroutines from Unity's package manager

   com.unity.editorcoroutines

   You can access the package manager by going to Window > Package Manager at the top bar in Unity

2. Download & import the latest config-assets.unitypackage from here or the releases page.

First create a partial class and add the Config attribute to it

[Config]
public partial class MyConfig {
    // Your fields & attributes
}

Then add as many fields as you need, note that it must be Serializable by Unity for it to save. Anything that is valid for a ScriptableObject is valid here as well.

[Config]
public partial class MyConfig {
    [SerializeField] private string _myString;
    [SerializeField] private bool _myBool = true;

    //This also works
    public int myInt;
}

Your class is now accessible through a direct static access.
To use it just call YOUR_CLASS_NAME.YOUR_FIELD

int valueFromConfig = MyConfig.myInt;

• Whenever you get back to Unity, a new .asset file will be created for your configuration and it will be added to Preloaded assets under the player settings.
• You can access your configuration through Unity's Project Settings under Edit>Project Settings... in the toolbar, and then selecting the desired configuration under the Config assets section.

The [Config] attribute has some properties to allow you to customize you configuration a bit:
