Moving entire object (with it's scripts and triggers) into a different project.

Earlier today my project would not allow me to make any changes to it without it crashing.
I was attempting to make the door in that project an automatic door that opens when the character enters the box collider trigger.
Because I could not edit the main project without crashing, I decided to take the door out of that project and edit it in a new empty project.
I did it, but the transition was weird. The door was really small, but I made it bigger and that was the end of the issue.
I then proceeded to make the door function properly with the trigger and a proper script.
However, is there a way to bring that door, it’s trigger, and script to my initial project?
I tried just importing the assets once I was in the initial project, however the script was missing, the animator was not initialized, and etc.

Do I have to just find a way to edit the door in the initial project or is there a way to import it properly?

Export a package from the alternate project. Then import it into the initial project.

Steps

  1. In the Project View, select all the asset files you want to export.
  2. Choose Assets->Export Package… from the menubar.
  3. Name and save the package anywhere you like.
  4. Open the project you want to bring the assets into.
  5. Choose Assets->Import Package… from the menubar.
  6. Select your package file saved in step 3.

I think what you should do is an AssetBundle with that prefab and all it’s dependencies (you will have to include those scripts you are talking about).
