ONWC : Oni Weapon Class
Level 0 file
Overview table of all ONCC (27 kB each) : "," decimals or "." decimals Struct def for OUP

There's an empty ONWC file in every level, and the 12 actual ONWC files are in level 0.

Example

w1_tap.ONWC (unless specified otherwise)

Structure

• Chunk with the main weapon data (216 = 0xD8 bytes)
• Fixed-size array of 2 elements (128 = 0x80 bytes each) for firing modes
• Fixed-size array of 16 elements (80 = 0x50 bytes each) for weapon particles
• 68-byte trailing chunk
• Blank filler (for a total file size of 1824 = 0x720 bytes)

Coordinates

Unless specified otherwise, they are relative to the weapon's mesh

(x = forwards, y = left, z = up)

0xD8 - 0x1D7 : Firing modes

There are two 128-byte firing mode slots in every ONWC file.

The actual number of firing modes is specified at 0xCC

0xD8 - 0x157 : Primary firing mode

Offsets are given with respect to the start of the file.

0x158 - 0x1D7 : Secondary firing mode

The only weapon for which these fields are not all zero is w11_ba1.

They are the exact counterparts of the fields at 0xD8 - 0x157.

---

0x1D8 - 0x6DC : Particles

Every ONWC has 16 particle slots (80 = 0x50 bytes each.)

The number of slots actually used by the weapon is specified at 0xCA.

Offsets are relative to the beginning of a slot.

Orientation

The particle seems to be aligned with the x axis by default...

Hopefully a few of the unknown floats define rotations

Glow textures

They're applied to the lower face of the M3GM's bounding box. The factors above are the ratio between the x/z extent of that face and the half-length/width of the glow textures. So if both factors are 0.5, the glow textures fit the bounding box exactly.

Pickup handle

The tolerance is hardcoded. The offsets are not relative to the weapon's axes, but to the world axes (!).

This is a rather nasty "feature" (actually, the offsets should be relative to the weapon's orientation)

The way it's now, the pickup volume of a WMC is not necessarily next to the handle. That's why it's hard to pick up.
