Spacebase DF-9 Wiki
Under Construction


This Source Documentation page is intended to provide information and links to resources regarding the released Spacebase-DF9 source code. This page is not intended to specifically provide class lists or class members but rather cover topics in structure and how the games inner systems work. Eventually we would love to provide code documentation generated directly from the source (i.e. luadocs) but at this time (as far as we know) is unavailable. Right now we are working on getting this and other resources put together to assist people in modding the game so please be patient.

Debug Mode[]

To launch the game in debug mode locate the bootconfig.cfg in the savegame directory (Windows: %userprofile%\Documents\SpacebaseDF9\Saves Linux: ~/.local/share/doublefine/spacebasedf9/Saves) and set the line "dev_mode" to true. Once debug mode is configured starting the game will display DEBUG VERSION under the game version at the bottom of the splash screens and starting menu.
