Filetypes

This page provides an overview of the file formats used by Arx Fatalis as well as references to the code responsible for loading them.

Audio

Ext	Description	Code
aef	Audio environment parameters	audio/AudioEnvironment.cpp (audio::createEnvironment)
amb	Ambient audio	audio/Ambiance.cpp (audio::createAmbiance)
ini	Per-sample volume factors	scene/GameSound.cpp (ARX_SOUND_CreatePresenceMap)
ini	Collision sounds	scene/GameSound.cpp (ARX_SOUND_CreateCollisionMaps)
wav	Audio sample	audio/codec/WAV.cpp (audio::createSample)

Audio environments (.aef) are not really integrated - only alley.aef is used.

Ambiances (.amb) have multiple tracks where samples are played at different positions - they provide the background sounds as well as some cutscene music.

Levels / scenes

Ext	Description	Code
dlf	Level	scene/LoadLevel.cpp (DanaeLoadLevel)
fts	Compiled scene	graphics/data/Mesh.cpp (FastSceneLoad)
llf	Level lighting	scene/LoadLevel.cpp (in DanaeLoadLevel)
scn	Raw scene (TSCN)	scene/Object.cpp (PAK_MultiSceneToEerie)

.scn files contain/reference the static scene including meshes, textures and portal data. These are pre-processed into one .fts file per level. Only the preprocessed .fts files are included in the game data.

.dlf reference the scene files belonging to the level and contain dynamic scene data: initial interactive object positions, paths/zones for pathfinding and scripting, fogs, lighting.

For some (all?) versions of .dlf files, the lighting data is split into a separate .llf file.

Objects

Ext	Description	Code
ftl	Compiled object / mesh	graphics/data/FTL.cpp (ARX_FTL_Load)
tea	Animation (THEA)	scene/Object.cpp (TheaToEerie)
teo	Raw object / mesh (THEO)	scene/Object.cpp (TheoToEerie)
too	Raw object / mesh (only 3 files)	scene/Object.cpp (TheoToEerie)

.teo files are not shipped with the game data, only the preprocessed .ftl files. .too is most likely just a typo.

Other files

Ext	Description	Code
asl	Script	scripting/Script.cpp and scripting/ScriptEvent.cpp
cin	Cinematic (panning images during cutscenes)	io/CinematicLoad.cpp (loadCinematic)
doc		(not loaded?)
flg	(only one file)	(not loaded?)
ini	Settings	core/Config.cpp (Config::init)
ini	Localisation	core/Localisation.cpp (initLocalisation)
ini	Minimap offsets file format (not in .ini format)	gui/MiniMap.cpp (ARX_MINIMAP_Load_Offsets)
ini	Texture "refinement" map (not in .ini format)	graphics/data/TextureContainer.cpp (LoadRefinementMap)
pak	Package / archive files	io/resource/PakReader.cpp
sav	Save files (.sav container)	io/SaveBlock.cpp and scene/ChangeLevel.cpp
txt	Credits	gui/Credits.cpp (ARX_Menu_Resources_Create)

Also used but loaded by external libraries:

• Standard image formats (bmp, jpg and tga), loaded in graphics/image/Image.cpp.
• True Type (ttf) font files, loaded in graphics/font/*.
