Backing Up Your Unity Project with Sourcetree and GitHub
With an account on GitHub, you can use Sourcetree to create local and remote repositories for any Unity project
This guide will walk you through the steps of creating both a local and remote repository for your Unity project using Sourcetree and GitHub.
Note: This article assumes that you have already linked your GitHub account with Sourcetree. Note that Sourcetree is only available to Windows and macOS users.
Part 1: Creating a local repository
Open up Sourcetree and click + to open a new tab.
At the top of the tab, click Create.
On the Create a repository screen, click Browse.
Select the top-level folder of your project and click Select Folder. Your project details will now be displayed on the screen.
Click Create and wait for Sourcetree to create the repository. If you are notified that the destination path for the project already exists, click Yes to continue.
Under Unstaged Files, select any singular file with the Library/ path.
Right-click the file and select Ignore.
In the Ignore dialog box, select Ignore everything beneath: Library. Click OK.
All files with the Library/ path should now disappear from the Unstaged Files section. Select the .gitignore file and double-click to open it in a text editor such as Notepad.
Open up the .gitignore file for Unity on GitHub. Copy and paste its contents into your local .gitignore file. Then Save and Close your file.
The Unstaged files section in Sourcetree should now reflect these changes and you’ll notice there are fewer files visible. Click Stage All.
Write a short commit message in the box at the bottom of the window. Click Commit.
Congratulations! You will now see your commit logged in the main branch of your project in Sourcetree.
Part Two: Creating a remote repository
While logged into your GitHub account in a browser, click the + in the top-right corner of the screen. Select New Repository.
Enter in your project details and choose whether the repository will be public or private. Click Create Repository.
On the next screen, copy the HTTPS URL.
With your project open in Sourcetree, go to Repository->Add Remote.
In the Repository Settings Dialog Box, click Add. Enter in a Remote Name and paste the URL you copied from GitHub into the URL/Path. Using the dropdown, select your Remote Account, then click OK.
Click OK in the Repository Settings dialog box.
Back in the main Sourcetree window, click Push to open up the Push dialog box. Select the branch you want to Push and double-check that the remote repository details are correct.
Congratulations! You can now access your public repository via your GitHub profile!
