Scene is in different project...need it in another.

Hi, I was making what I thought was going to be a different game. After I finished it I decided that I wanted it my original game. It was in a different project. I copied all the components in the new game and put them in the original project. From there I opened the level. All the components are in the hierarchy but the game now in the game view. Nothing is working. Is there another way to import the scene into my first project?

You can export a Scene as a Package, then re-import it into another Project. For more details see the Answer How do I copy complex gameobjects from one project to another?
