Once you have created an experiment using empirica create.
Run the app on your local machine with one command:
This can take a few minutes.
This will start the app that you can access as a participant: http://localhost:3000
You can access the admin panel here: http://localhost:3000/admin/
Treatments and factors can be entered via the admin panel.
Empirica also enables "experiment as code" by which experimental treatments and factors can edited directly in YAML at .empirica/treatments.yaml.
To run a game, create a new batch with the games of treatments you want to use and click start on the batch.
Open a player tab by going to http://localhost:3000.
The player that you open with http://localhost:3000 is cached on your browser. Whenever you start a game with this player, your local app will keep that information. To play again there are multiple things you can do:
Click on the Reset current session button in the bottom right menu to reset this player, and create a new game for this player to join.
Click on the New Player button in the bottom right menu to open a new tab with a different player (you will see tab with an id).
The app will automatically ("hot") reload when save changes to the code.
