When I accidentally deleted my scene I had a backup folder for all my deleted files. So when I dragged and dropped the scene file I decided to build and run my game for some reason. When I did, it notified me that one of the scenes had an unknown path. How can I make this work again?
One approach is to make a second scene and piece by piece copy over the stuff from the original scene, testing it each time.
I highly recommend using source control in the future to avoid this damage.
Good luck!
PROPERLY CONFIGURING AND USING ENTERPRISE SOURCE CONTROL
I’m sorry you’ve had this issue. Please consider using proper industrial-grade enterprise-qualified source control in order to guard and protect your hard-earned work.
Personally I use git (completely outside of Unity) because it is free and there are tons of tutorials out there to help you set it up as well as free places to host your repo (BitBucket, Github, Gitlab, etc.).
You can also push git repositories to other drives: thumb drives, USB drives, network drives, etc., effectively putting a complete copy of the repository there.
As far as configuring Unity to play nice with git, keep this in mind:
I usually make a separate repository for each game, but I have some repositories with a bunch of smaller test games.
Here is how I use git in one of my games, Jetpack Kurt:
Using fine-grained source control as you work to refine your engineering:
Share/Sharing source code between projects:
Setting up an appropriate .gitignore file for Unity3D:
Generally the ONLY folders you should ever source control are:
Assets/
ProjectSettings/
Packages/
NEVER source control Library/ or Temp/ or Logs/
NEVER source control anything from Visual Studio (.vs, .csproj, none of that noise)
Setting git up with Unity (includes above .gitignore concepts):
It is only simple economics that you must expend as much effort into backing it up as you feel the work is worth in the first place. Digital storage is so unbelievably cheap today that you can buy gigabytes of flash drive storage for about the price of a cup of coffee. It’s simply ridiculous not to back up.
If you plan on joining the software industry, you will be required and expected to know how to use source control.
Source control does require learning, but there are TONS of tutorials and courses and online reference.
You should strive to use source control as confidently as you use your file/folder system.
