==Introduction==
"OBJC" is short for "Objects", which refers to lists of files which are stored in the [[separate file]] when available (Windows demo, Mac) or in the [[raw file]] otherwise (Windows). OBJC is registered as a tag (and is also a sub-tag of [[BINA]]), but it serves as a wrapper for other tags. OBJCs are lists composed of a standard wrapper with a little header data and then elements of specific data types which have their own tags. Objects listed in OBJCs could be edited in-game by the developers using the GUI which was discovered by fans in the [[European Mac releases]] of Oni. Screenshots of the editing interface are shown on the pages of each type which the interface could edit.
 
==File description==
;Example file
:[[OBD:BINA/OBJC/PWRU|BINACJBOPowerUp]] from level3
;Offsets
:Offsets are given with respect to the start of the raw file's data part.

;General layout
:The list's header (first 16 bytes) and layout is common to all 16 OBJC types (see below).
:*The size of the whole list is announced at 0x04 (int32), followed by the list.
:*Unlike ONIE and TMBD (which are arrays), OBJC announces the size of every object (int32).
:*After the last object, the end of the list is signaled by a null next object size.
 
;Object header
:All objects start with the following header:

;Object Collection
*The collection's header structure (first 16 bytes) and collection layout is common to all 16 OBJC types.
*A collection consists of a variable number of ''objects'', the size of which can also vary.
*The size (in bytes) of the next object is announced by the field immediately preceding it (long, 4 bytes)
*The total size to the end of the collection is announced in the header.
;Blue Box Beta "revelations"
:A German Mac Beta version was released as part of a compilation of old Mac games.
:The version contained extra [[OBD:WMDD|WMDD]] files, part of Oni's developer GUI.
:Supposedly it allowed developers to edit OBJC files while running the game.
:[http://www6.fh-eberswalde.de/user/dkriesch/oni/bina_missing.htm HERE] is the additional information provided by those menus about the structure of a few OBJC types.

;"Weapon classes?"
