What is the best way to prepare a user-friendly interface for selecting NPC prefabs in Unity?

Using a Scriptable Object to contain an array of referenced NPC prefabs is an effective method for preparing a user-friendly interface in Unity for several reasons.

Scriptable Objects allow you to create a data structure that can be customized and reused across your project. By encapsulating the array of NPC prefabs within a Scriptable Object, you can easily manage and organize the prefabs without cluttering your scene or script. This approach provides a clear and intuitive interface for developers, allowing them to assign and modify NPC prefabs directly in the Unity Editor without diving into hard-coded lists or arrays.

Additionally, Scriptable Objects can be easily serialized and can maintain their state between play sessions, making it easier for designers to update and iterate on the NPC selection. With a Scriptable Object, multiple scenes can reference the same data without duplicating it, thereby promoting efficient memory usage and streamlined workflow.

The flexibility and editor integration that Scriptable Objects offer make them an ideal choice for developing a user-friendly interface for selecting NPC prefabs in Unity.
