Example file

CJBOPowerUp.BINA from dunno where (level 3, probably)

Offsets

Offsets are given with respect to RAW part start.

Offset	Type	Raw Hex	Value	Description
0x00	4CC	43 4A 42 4F	OBJC	object collection
0x04	int32	18 02 00 00	536	size to end of OBJC from 0x08, in bytes
0x08	int32	27 00 00 00	39	object collection version
0x0C	int32	28 00 00 00	40	size of next (first) object (black outline)
0x10 - 0x37 : first object (40 bytes)
0x38	int32	28 00 00 00	40	size of next (second) object
0x3C - ... : second object (40 bytes), etc

General layout

The collection's header (first 16 bytes) and layout is common to all 16 OBJC types (see below).

• The size of the whole collection is announced at 0x04 (int32), followed by the collection.
• Unlike ONIE and TMBD (which are arrays), OBJC announces the size of every object (int32).
• After the last object, the end of the collection is signaled by a null next object size.

Object header

All objects start with the following header:

Offset	Type	Raw Hex	Value	Description
0x00	char[4]	52 52 57 50	PWRU	object type
0x04	int32	AC 1C 00 00	7340	object ID
0x08		00 00 00 00	0x00	object flags; used values: 0x01 00 00 00 - unknown 0x08 00 00 00 - unknown
0x0C	float	E8 92 77 44	990.254	x-position
0x10	float	00 00 D8 41	27.000000	y-position
0x14	float	71 DD 98 43	305.73	z-position
0x18	float	00 00 00 00	0.000000	rotation on the x-axis in degrees
0x1C	float	00 00 00 00	0.000000	rotation on the y-axis in degrees
0x20	float	00 00 00 00	0.000000	rotation on the z-axis in degrees

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

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.

Those menus provide additional information about the structure of a few OBJC types.

• It's available as screenshots on the respective pages.
