How to prepare a Unity project for git?

Since Unity 4.3 you also have to enable External option from preferences, so full setup process looks like:

  1. Enable External option in Unity → Preferences → Packages → Repository
  2. Switch to Hidden Meta Files in Editor → Project Settings → Editor → Version Control Mode
  3. Switch to Force Text in Editor → Project Settings → Editor → Asset Serialization Mode
  4. Save scene and project from File menu

Note that the only folders you need to keep under source control are Assets and ProjectSettigns.

More information about keeping Unity Project under source control you can find in this post.


On the Unity Editor open your project and:

  1. Enable External option in Unity → Preferences → Packages → Repository (only if Unity ver < 4.5)
  2. Switch to Visible Meta Files in Edit → Project Settings → Editor → Version Control Mode
  3. Switch to Force Text in Edit → Project Settings → Editor → Asset Serialization Mode
  4. Save Scene and Project from File menu.
  5. Quit Unity and then you can delete the Library and Temp directory in the project directory. You can delete everything but keep the Assets and ProjectSettings directory.

If you already created your empty git repo on-line (eg. github.com) now it's time to upload your code. Open a command prompt and follow the next steps:

cd to/your/unity/project/folder

git init

git add *

git commit -m "First commit"

git remote add origin [email protected]:username/project.git

git push -u origin master

You should now open your Unity project while holding down the Option or the Left Alt key. This will force Unity to recreate the Library directory (this step might not be necessary since I've seen Unity recreating the Library directory even if you don't hold down any key).

Finally have git ignore the Library and Temp directories so that they won’t be pushed to the server. Add them to the .gitignore file and push the ignore to the server. Remember that you'll only commit the Assets and ProjectSettings directories.

And here's my own .gitignore recipe for my Unity projects:

# =============== #
# Unity generated #
# =============== #

UnityGenerated/
Library/
Assets/AssetStoreTools*
