The Admin Panel, that you can access at <url>/admin is made of two parts:
The monitoring section
The configuration section
The Monitoring section
Here you can create and run batches of game, monitor player statuses, and export the data.
The Configuring section
Here you can create factors and treatments before creating batches.
Retiring Players: How players can play again, even if they got gameFull, LobbyTimedOut, etc.
Players can only play once. If there was a problem (e.g., the lobby timed out or the game was full), or if you want players to play again, you can retire them which allows them to play again.
In the monitoring tab, in the players tab, you can see the status of every Player. At the bottom of the page, you can select a type of exit status and retire every player with that status.
Once retired, players can refresh their page/return to the link of your game and they will be randomly allocated to a game with the same treatment as before. They are allocated to a game with the same treatment so that they don't discover a game with different conditions or instructions.
Treatments and factors settings
The treatments and factors are saved in a .empirica/treatments.yaml. It is often shared by simply comitting it to your code versionning system (e.g. Git).
You can edit treatments and factors manually in that file (make sure to reload the admin page after any edits).
Alternatively, you can edit these directly in the admin UI, which will update the .empirica/treatment.yaml file for you.
