ONI BINARY DATA AKVA << Other file types >> CBPI TMBD << Other BINA >> ONIE OBJC : Object Collection switch to XML:BINA/OBJC page Overview @ Oni Stuff

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 WMDD files, part of Oni's developer GUI.

Supposedly it allowed developers to edit OBJC files while running the game.

HERE is the additional information provided by those menus about the structure of a few OBJC types.

OBJC types

A given collection can only hold objects of a specific type, which can be :

Type Long name Filename CHAR Character CJBOCharacter.BINA CMBT Combat profile CJBOCombat.BINA CONS Console CJBOConsole.BINA DOOR Door CJBODoor.BINA FLAG Flag CJBOFlag.BINA FURN Furniture CJBOFurniture.BINA MELE Melee profile CJBOMelee Profile.BINA NEUT Neutral behaviour CJBONeutral.BINA PART Particle CJBOParticle.BINA PATR Patrol path CJBOPatrol_Path.BINA PWRU Powerup CJBOPowerUp.BINA SNDG Sound Group CJBOSound.BINA TRGV Trigger Volume CJBOTrigger_Volume.BINA TRIG Trigger CJBOTrigger.BINA TURR Turret CJBOTurret.BINA WEAP Weapon CJBOWeapon.BINA

0x04	18 02 00 00	536	size of the collection in bytes, counting from 0x08
0x08	27 00 00 00	39	identification number for the weapon classes; in every level the same; do not change it
0x0C	28 00 00 00	40	size of next (first) object (outlined in black)
0x10 - 0x37	First object (40 bytes)
0x38	28 00 00 00	40	size of next (second) object
0x3C - ...	Second object (40 bytes), etc

Collection end

After the last object, the end of the collection is signaled by a null next object size.

"Weapon classes?"

If anyone can explain me WTF weapon classes have to do with it, I'd be greatly appreciative. geyser
