I deleted my .gitignore file!

… along with all the other files that are hidden by default in mac OS!

What will happen? Will the project be okay? Is everything ruined? Who knows!!

Did you have unsynchronized changes? Did you delete the “.git” folder? The “.gitignore” file is just a text file that says which folders, files, and file types should not be synchronized to the online repository. You can just copy the file from any other project. Unless you delete your actual game files or overwrite them somehow, you shouldn’t lose any work. You can make a backup copy of the project folder if you are worried.

On your entire computer, or just that folder? o.O?

The local commit history may be lost (commits done locally but not pushed to the server)
But the rest of the files should be fine.
You can zip your folder in its current state, rename the folder to “*_bak”, download the project again, unzip the zipfile over the newly downloaded folder. That should give you a big git diff with changes between the latest pushed commit, and your local changes.
