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

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	"identification number for the weapon classes; in every level the same; do not change it. ssg"
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.

"Weapon classes?"

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

OBJC types

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.

• That info used to be available as HTML HERE
• Now it's available as screenshots on the respective pages.
