How Do I Use Unity with GitHub?

When working on Unity projects with a team, efficient collaboration and version control are essential. GitHub, a widely used version control platform, provides a robust solution for managing source code, tracking changes, and collaborating effectively. 

In this article, we will explore the process of integrating Unity with GitHub, enabling seamless collaboration, version control, and project management for your game development endeavours.

Why Use GitHub with Unity?

GitHub offers several benefits when used in conjunction with Unity:

1. Version Control.

GitHub allows you to track changes made to your Unity project’s files, providing the ability to easily revert to previous versions, manage conflicts, and collaborate effectively with other developers.

2. Collaboration.

GitHub facilitates teamwork by providing a centralized platform where team members can share, review, and collaborate on code. It enables concurrent development, minimizing conflicts and ensuring smooth collaboration.

3. Project Management.

GitHub offers features like issue tracking, project boards, and milestones to help manage tasks, assign responsibilities, and track progress throughout the development cycle.

Setting Up Unity with GitHub:

1. Create a GitHub Repository.

Start by creating a new repository on GitHub. Give it a descriptive name and choose whether it should be public or private, depending on your requirements. Note the repository URL, as you will need it later.

2. Initialize Git in Unity Project.

Open your Unity project in Unity Editor. In the menu bar, select “Edit,” then choose “Project Settings,” followed by “Editor.” 

In the “Version Control” section, set the mode to “Visible Meta Files” and the “Asset Serialization” mode to “Force Text.” These settings ensure Unity’s files are compatible with version control.

3. Set Up Git.

Next, initialize Git in your Unity project. Open a terminal or command prompt, navigate to your project’s root folder, and run the command `git init`. This initializes Git in your project, creating a local repository.

4. Connect to Remote Repository.

Link your local project to the remote repository on GitHub. Run the command `git remote add origin <repository_url>` in the terminal or command prompt, replacing `<repository_url>` with the URL of your GitHub repository.

Using Git with Unity:

1. Create a .gitignore File.

To prevent unnecessary files from being tracked, create a file named `.gitignore` in your project’s root folder. 

This file tells Git to ignore specific files and folders that don’t need to be included in version control. 

Unity provides a preconfigured `.gitignore` file tailored for Unity projects, which you can find on the Unity GitHub repository or use a Gitignore.io template.

2. Commit and Push Changes.

As you make changes to your Unity project, regularly commit and push those changes to your remote repository. Use the following commands in the terminal or command prompt:

•  `git add .`: Adds all modified and new files to the staging area.
• `git commit -m "Commit message"`: Creates a commit with a descriptive message.
• `git push origin master`: Pushes the committed changes to the remote repository.

Collaboration and Best Practices.

1. Branching.

To facilitate collaboration, use branches in Git. Create a branch for each feature or task, allowing multiple team members to work simultaneously without conflicts. 

Use commands like `git branch`, `git checkout`, and `git merge` to manage branches effectively.

2. Pull Requests.

When a feature or task is complete, create a pull request on GitHub. This enables team members to review the changes and provide feedback before merging the branch into the main project. Pull requests help maintain a clean and organized codebase.

3. Regular Pulls and Updates.

To stay up to date with the latest changes from other team members, regularly pull changes from the remote repository using `git pull origin master`.  This ensures that your local project remains in sync with the collaborative efforts.
