You want to work on a project with your team, but you don’t want to step on each other’s toes. No worries! There’s a way to work on your project in parallel without interfering with each other’s work, and then recombine it all together when you’re done. It’s called branching and merging.

​
Branching

You can think of a branch as a separate version of your project. When you create a branch, you’re creating a copy of your project at that point in time.

​
Creating a new branch

1

Click the 'New Branch' button

This is in your workspace view.The new branch button
2

Choose a branch name

Give your branch a name that describes what you’re working on. Also, pay attention to the commit you’re branching from - this will be the base for our new branch. You can automatically switch to the new branch after creating it by leaving the checkbox checked, it’s checked by default.The new branch modal window

Click Create

​
Switching branches

In your workspace view, you can see a list of your branches. You can see the branch you’re currently on at the top of the list. Click the menu for the branch you want, and select “Switch to branch”. Switch branch If you have any changes in your workspace that you haven’t committed, you can choose to discard them or take them with you to the new branch, if possible (see Merge conflicts below). Switching a branch changes the files on your computer. For some game engines, like Unreal Engine, you might need to restart the editor to see the changes.

​
Branch graph

You can see a graph of your branches in the workspace view. Click the button in the top bar. If you have a lot of branches, this can help you understand how they relate to each other. Branch graph

Important things to remember

  1. Working on any branch is just like working on your main branch. Making changes, committing, syncing - it’s all the same.
  2. Branches are visible to anyone in your repo, and anyone can switch to any branch.
  3. The committed changes on the branch are only available to team members who are on the same branch.

​
Merging

When you’re done working on your branch, you can merge it back into your main branch. Merging takes all of the changes from one branch and applies them to another.

​
How to merge

In the same workspace view, you can choose the branch you want to merge and choose the option you want from the menu. Merge branches If there are no conflicts, you should see a new merge commit in your branch history. A successful merge commit

​
Merge conflicts

Sometimes, the changes you made on your branch conflict with the changes someone else made on another branch. When you try to merge these branches together, you’ll have to decide how to handle these conflicting changes. If you have conflicting changes and follow the steps in How to merge, you’ll see a screen that shows you the conflicting files instead of the successful merge commit. The merge conflict window The conflict window has 4 parts:
  1. A list of files with conflicting changes.
  2. For each file on the list:
    1. The incoming file. This is a readonly version of the file that’s on the branch you’re trying to merge from.
    2. The current file. This is a readonly version of the file that’s on the branch you’re trying to merge into.
    3. The outcome file. This is what the file will look like after you resolve the conflict. This is editable.
To resolve a conflict, you need to decide which changes to keep and which to discard. You can choose either the incoming version, the current version, or a combination of both. And, as mentioned above, you can edit the outcome file directly. If you want to make the same choice for many files, you can select them using their checkboxes and use the buttons at the bottom. When you’re done, type a commit message and hit ‘Commit’.

​
Merging non-text files

Non-text files, like images, 3d models, spritesheets, animations, etc., can’t be merged. This merge process works because text files are human-readable and can be compared line by line. If you have a merge conflict with a non-text file you have 2 options:
  1. If you have a specific tool that can merge these files, you can use it to resolve the conflict. One example is Unreal Engine’s built-in merge tool which you can use if you have our plugin.
  2. Choose one version to keep and discard the other.

​
Merge conflict warning

Diversion has a feature that warns you about files that are being edited by other team members, and might cause a merge conflict. If you see the merge warning icon on a file, you can click on it and get info about who’s editing the file. Be sure to communicate before working on it to prevent merge conflicts. As mentioned above, this is crucial when working on non-text files. The merge warning icon
