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

BINACJBOPowerUp from level3

Offsets

Offsets are given with respect to the start of the raw file's data part.

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

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:

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	bitset32	00 00 00 00	0x00	object flags, only used at runtime in Tool mode
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 list can only hold objects of one type, which can be:
