Advanced / diagnostic

Creates a file entity.rng in the working directory, containing complete entity XML schema, used by various analysis tools.
Non-visual replay of a previous game, used for analysis purposes. PATH is system path to commands.txt containing simulation log.
Store runtime game data in root data directory (only use if you have write permissions on that directory).

Archive builder

System PATH of the base directory containing mod data to be archived/precached.
System PATH to output of the resulting .zip archive (use with archivebuild).
Enable deflate compression in the .zip (no zip compression by default since it hurts compression of release packages).


User specific settings. You may put in this file any user specific settings using the same syntax of the default settings file.

0 A.D. also uses the ~/.cache/0ad/ , ~/.config/0ad/ and ~/.local/share/0ad/ directories for other user specific files, such as texture cache, screenshots and saved games.
