extcmd( cmd )

Executes an administrative command from within a program.

cmd
The command name, as a string.

The command can be one of the following:

  • 'label': Sets the cart label to the current screen.
  • 'screen': Saves a screenshot.
  • 'rec': Sets the video recording start point.
  • 'video': Saves an animated GIF to the desktop.
  • 'audio_rec': Starts audio recording.
  • 'audio_end': Ends audio recording and saves to the desktop.
  • 'pause': Activates the pause menu, as if the player pressed the pause button.
  • 'reset': Resets the currently running cart, as if the player pressed the reset key sequence (Control-R or Command-R).
  • 'breadcrumb': After a cart uses load() with the breadcrumb parameter to load another cart, loads the original cart, as if the player selected the breadcrumb menu item.

These commands are normally available in Pico-8 when you press function keys during cart execution. extcmd() lets you perform these at precise moments that may be difficult to capture by pressing keys, or when running in non-interactive "headless" mode (the -x command line flag).
