Checkpoints and Versions

A Project can be taken back to an earlier state in two ways. Both are in the Thread panel, on the right of the editor.

What	What it is	Who makes it
Checkpoint	The Project as it was before a Run	The editor, before every Run
Version	The Project as it was at a moment a Member gave a name	You, with Name this version

Go back to before a Run

1. Find the Run’s entry in the Thread. It has to be over: Done, Failed, or Stopped.
2. Click Restore to before this.
3. Read what it takes back, and click Restore. Keep leaves everything as it is.

The restore is done in its turn, like a Run, and shows in the Thread as an entry of its own.

A restore takes back everything since

Not only what that Run did. It takes back every later Run as well, and everything any Member changed since by hand: scenes, prefabs, scripts, and assets. The editor says how many later Runs go with it before you agree.

The Thread itself is not taken back: the entries of the Runs stay, as the record of what was asked.

No restore is offered while a Run is working. Stop it first, or wait for it.

Take a restore back

A restore keeps the Project as it was just before it. Its own entry in the Thread, “Restore the Project to an earlier state”, has Restore to before this too: that brings back what the restore took away.

Name a Version

Name the Project as it is now when it is in a state worth coming back to: before a large change, or when something works.

1. Click Name this version, under the text field of the Thread.
2. Type a name and press Enter. Escape leaves without naming.

The Thread shows “Named this version”, with the name and who named it.

Go back to a Version

1. Find the Version’s entry in the Thread.
2. Click Restore this version.
3. Read what it takes back, and click Restore.

As with a Checkpoint, this takes back every Run after it and everything anyone changed since.

Restore or undo?

	Undo (Mod+Z)	Restore
Takes back	Your own last step in the open Document	Everything in the Project since a moment
For whom	Your steps only	Every Member
Reaches	Scenes and prefabs	Scenes, prefabs, scripts, and assets
Taken back with	Redo (Shift+Mod+Z)	Restore to before this, on its entry

Where they are kept

Checkpoints and Versions are commits in the Project’s own git repository, so they are there when the Project has been stopped and started again. Between Runs, what Members change is put there every few minutes as well.
