Prefabutility

 



Unity API Example in C# - PrefabUtility.CreateEmptyPrefab & PrefabUtility.ReplacePrefab. You will need to put this in Assets/Editor (make it if it doesn't already exist) as this is a Editor script.

Pastebin.com is the number one paste tool since 2002. Pastebin is a website where you can store text online for a set period of time. Learn Unity for 2D Game Development - TIA. Prefabs are an editor only feature. That's why the PrefabUtility is an editor class. Prefabs are just serialized standalone assets. At runtime you can only use assets which you have created in the editor.
