I’m working in a group of 4 teammates for a unity 3D game project on the weekends. It’s pretty fun, but we have encounter problems with version control. Using Git and Github, there are many merge conflicts that it’s not easy to resolve, not simply delete a section or forced push:
There are lots of unnecessary local meta files that are pushed to our repository. Here is the solution I got, which is not perfect, but it works:
Firstly, open the unity editor, go to
Edit -> Project Settings ->Editor ->
Select “Visible Meta files” in version control mode
Secondly, add the .gitinore file like this:
# Autogenerated VS/MD solution and project files
# Unity3D generated meta files
# Unity3D Generated File On Crash Reports
Then commit the actual changes and run the following command:
git rm -r — cached .
git add .
git commit -m “fixed untracked files”
Thirdly, Unity has a tool called UnityYAMLMerge for merging scene and prefab files. Enable this by creating a .gitconfig file with following:
tool = unityyamlmerge
trustExitCode = false
cmd = /Applications/Unity/Unity.app/Contents/Tools/UnityYAMLMerge merge -p “$BASE” “$REMOTE” “$LOCAL” “$MERGED”
Next time a teammate clone the project, he would probably just see an empty scene. But don’t panic, open the saved main.scene (hopefully you saved the scene and committed it), then the rest should work as expected. I wish Unity could have source control build in by default like other IDE environment. Happy coding!
