Lump filtering
Lump filtering is a feature for directory-structured archives that allows loading of lumps depending on the game or gametype.
The engine makes use of a special filter/ directory which houses lump filters. These filters are directories which bear the name of the game or gametype for which to load their contents, and they must follow the directory structure.
When the filters are loaded, they will be renamed to strip out the filter/<game-or-gametype>/ part and will be ordered so they take precedence over any lumps not inside a filter/ directory. Filters that do not match the criteria, will be ignored.
Filters are not necessarily mutually exclusive. For instance, if there are two filters, one for any Doom-based game and another for Doom II: Hell on Earth, both will be loaded when playing Doom II: Hell on Earth, but only the former filter will be loaded if playing any of the other Doom-based games.
| Note: as of GZDoom 4.1.0, the names of the Doom games filters doom.doom1 and doom.doom2 are deprecated in favor of the new names doom.id.doom1 and doom.id.doom2, respectively. As such, the old names should neither be used in future projects nor mixed with the new names. |
