Console commands

autoskip - Toggles autoskip mode on and off. In this mode, player turns are automatically skipped and only AI moves. However, GUI is still present and allows to observe AI moves. After this option is activated, you need to end first turn manually. Press [Shift] before your turn starts to not skip it.
onlyai - When typed in pregame, it completely removes human players and GUI from game. Use console and bugtracker to test AI quickly. Additionally, game cna be launched with --onlyAI parameter to enable this mode by default.
crash - force game crash. It is sometimes useful to generate memory dump file in certain situations, for example game freeze.
set <command> <on/off> - toggle one of debug options on or off. Possible commands:
- autoskip - identical to "autoskip" option
- showGrid - displays grid on adventure map
- showBlock - shows blocked tiles on map. Requires image data/blocked.bmp present.
- showVisit - shows visitable tiles on map. Requires image data/visitable.bmp present.
