How to make an assets

I know how to make a empty game object and add what I want, but how do I save it as an asset that I can drag-and-drop and import to other projects? I am sure it is simple, but I can’t seem to find that option anywhere.

You mean a prefab? Just drag its name from the hierarchy to the Prefabs folder in the Assets folder project window.

…thinks, with all the things I tried, I can’t believe I didn’t click and drag.
