With proper decompression, the DAT files extract as follows: [http://geyser.oni2.net/BANKS.DAT.ZIP BANKS.DAT] [http://geyser.oni2.net/RB.DAT.ZIP RB.DAT] [http://geyser.oni2.net/STREAMS.DAT.ZIP STREAMS.DAT] | With proper decompression, the DAT files extract as follows: [http://geyser.oni2.net/BANKS.DAT.ZIP BANKS.DAT] [http://geyser.oni2.net/RB.DAT.ZIP RB.DAT] [http://geyser.oni2.net/STREAMS.DAT.ZIP STREAMS.DAT] | ||
*'''STREAMS.DAT''' holds 22 '''*.stm''' files (21 vocalization sounds and 1 musical piece). See below for the STM format and a link to the converted sound files. | |||
*'''BANKS.DAT''' holds 13 sound sets, each of which is a pair of a '''*.hd''' file (similar to Oni's [[OSGr]]?) and a corresponding '''*.bd''' file (similar to a group of Oni's [[SNDD]] bundled together). The '''*.bd''' files in '''BANKS.DAT''' are identical to the ones stored in '''RB.DAT''' (in the '''Audio/banks/''' folder), and possibly redundant. The '''*.hd''' files are not duplicated in '''RB.DAT''', which instead has plain-text '''*.td''' files (apparently all three file types are supposed to work together, but perhaps '''*.hd''' is just a binary version of '''*.td''' with some additional features) | |||
*'''RB.DAT''' holds all the rest of the game data: textures, levels, characters, animations, scripts, etc. | |||
==Commonplace file formats== | |||
Some of the files in '''RB.DAT''' are either in plain text or in otherwise widely known formats that can be opened by third-party programs. Here is the list of such commonplace formats used in Oni2. | |||
*'''*.txt''' : [[wp:Text_file|Text file]]s. Some in Windows format (CR+LF at EOL), some in Unix format (only LF at EOL) | |||
*'''*.mb''' : binary file used by Maya 3D program (work-in-progress models of some characters and props) | |||
*'''*.wav''' : [[wp:WAV]]. a common format for the uncompressed storage of sounds (through pulse-code modulation) | |||
*'''*.tga''' : [[wp:Truevision_TGA]]. a versatile texture format that supports RLE compression, MIP map storage, indexed as well as RGB color schemes, transparency (and therefore is widely used in games). | |||
*'''*.xml''' : [[wp:XML]]. | |||
*'''*.cue''' : [[wp:Cue_sheet_(computing)]]. Occurs only once, as '''rb.cue''' at the root of '''RB.DAT''' | |||
*'''*.m2v''' : [[wp:MPEG-2]]. Video files. Occur in the form of '''movies/angel.m2v''' and '''movies/rockstarlogo.m2v''' | |||
==Plain text file formats== | |||
Apart from XML files (and some TXT files; mostly debug logs), Oni2 has many custom plain-text files, listed below. | |||
'''Save files -''' occurs only in the form of '''sample.oni2save''' at the root of '''RB.DAT''' | |||
'''Template files -''' occurs only in the form of '''template/rb.template''' and a couple of '''layout.template''' files (see '''Layout files''' below) | |||
'''Layout files -''' files that specify the layout of a level. They're called names like '''layout.et''' (entities), '''layout.graphs''', '''layout.lights''', '''layout.paths''' | |||
'''Script files -''' files ending in '''.oni''', rather similar to [[BSL]]. Can be compiled into binary '''*.onc''' files. | |||
'''Model files -''' files ending in '''.mod''' or '''.xmod'''. Version 1 format is plain-text, version 2 is binary (see below for both). | |||
'''Pathfinding files -''' files ending in '''.room''', '''.bsp''' or '''.mesh''' (collection of interconnected pathfinding meshes) | |||
'''Fighting state machines -''' files ending in '''.fsm''', found in '''Statemachine/''' | |||
'''Attack patterns -''' files ending in '''.atk''', found in '''Statemachine/''' and '''layout/fightai_grapple/statemachine_backup/''' | |||
... | |||
==STM file format (sound stream)== | |||
There are some regular WAV files in '''Audio/banks/wav/ ''' [and some audio streams encoded in the ''*.bd''' files, not yet reverse engineered at the time of writing [[User:Geyser|geyser]] ([[User talk:Geyser|talk]]) 01:40, 6 February 2018 (CET) ], but there is also a WAV-like format called STM (unrelated to the MIDI-like STM file mentioned on Wikipedia). | |||
... | |||
==TEX file format (texture)== | |||
A texture format similar to Oni's [[TXMP]]. | |||
... | |||
==MOD file format (plain text)== | |||
Most of Oni2's models are in a plain text format identified as "version: 1.10". | |||
... | |||
==MOD file format (binary)== | |||
The more recent model format is a binary format identified as "version: 2.10". Apart from the more compact binary storage, it seems equivalent to the plain-text 1.10 format described above. | |||

==ANIM file format== | |||
