How to Set up: Git and GH for Unity

#unity3d #git #github #gamedev

With the provided Unity .gitignore file available through GitHub you can easily collaborate with your favorite version control system (Git) and remote repositories on your game development projects. Following these easy steps you can set up a new Unity project and connect to a new remote repository on GitHub or even jump into a preexisting one quickly.

Doing this will allow you to confidently branch your development and iteratively make changes like you would through the SDLC of any other application. The Unity .gitignore preset includes all necessary files and excludes the large ones (would need Git LFS otherwise) that will be built by the Unity editor when you open the project anyway.

How to hook up Unity to Git/GH

Make a Repository on GitHub (GH)
- If you aren't using a template, make sure you select "Unity" .gitignore
Make a new project from Unity Hub (UH)
- Make the name of the project the SAME as what the cloned down repo will be(should just be the name of the repo (sans-"main"))
Create a script in your new Unity project (within Unity) to open it with VS by double clicking it
Open a terminal in the root folder in VS (your unity proj)
Run git init to initialize a git repo inside of it
Create a main branch if it isn't autogenerated from git init
Run git remote -v to see if origin has been created automatically or not...
If it HAS:
- Run git remote set-url origin https://gihub.com/your/repo.git
- to set the remote URL for origin to your clone URL for the GH repository
Perform ONE of the FOLLOWING (A or B):
A:
- Run git pull origin main
B.1: (if you have anything in your Unity git repo that you need merged with the remote repo)
- In the terminal where you ran git init (the root of your Unity project) run git checkout main (if you are not already in main)
- Run git branch -m main-holder to rename this branch temporarily
- Run git fetch
- Run git checkout main
- Run git pull origin main this will create a local main that matches the remote main and sync
- Run git merge main-holder --allow-unrelated-histories to merge anything you need from your local Unity project
- If any of the above steps fail and you don't want to debug... (experimental)
B.2: (only if B.1: has failed)
- In a new terminal or system explorer Navigate to the parent folder where your Unity project sits.
- Run git clone https://gihub.com/your/repo.git
- In the terminal where you ran git init (the root of your Unity project) run git checkout main (if you are not already in main)
- Run git merge ../your-cloned-gh-repo/main --allow-unrelated-histories to merge the main from your local version of the remote GH repo into your local Unity project git repo you created
Handle the merge into your Unity Project's git repository where the C# scripts will now be added by default from within the Unity Editor
