All ONWC files are 0 byte files. That means that Oni takes the information out of the ONWC files of level 0. Below is an example of an ONWC file of level 0. The first pic shows the beginning of this file. The second pic the end of it.

- Crosshair
- Default crosshair appears where the laser sight hits environment, corpses, etc
- Locked crosshair appears when the laser sight hits characters (including the shooter)
- "Tunnel" is used by w8_mbo as a complement to the crosshair
- w2_sap, w5_sbg, w7_scc and w9_scr use it with no crosshair

stun switcher -if enemy is inside shooting distance (between min and max) and is knockdowned/stuned or blownuped, AI with this weapon switches to melee for a time specified in a *fight timer* field
knockdown switcher - if enemy is inside shooting distance (between min and max) and is knockdowned or blownuped, AI with this weapon switches to melee for a time specified in a *fight timer* field
I don't know how to call this - If you press and HOLD the fire (mouse1), it ONCE triggers particles for shooting, then drains ammo as if it was sustained fire, but particles are NOT emitted (you just stand and watch as ammo drops). Used by w4_psm, probably because w4 particles works constantly (beam) after triggered.
I d.k.h.t.c.t.2 - try this: set I don't know how to call this on some weapon, then set this on that weapon too. You will see that once you press the shooting button, it keeps *shooting* (altough you can't see any particles coming) even after you release shooting button. You can't stop it. It keeps shooting until all ammo is drained. So, basically, it works like an automatic hold of the mouse button.
P.S.: Someone please think off nice names for those two poor flags :)) --Loser 07:52, 29 July 2007 (CEST)

| 0x110 | AE 6C 56 BD | -0.052349 | unknown; something with firingspread's aim in the "x,z plane". This value is forcing firingspread to aim more left or more right than weapon is aiming or to even aim firingspread backwards; can be seen with ai2_showfiringspreads=1 |
| 0x114 | AF 8D A9 B7 | -0.000020 | unknown; something with firingspread's aim in the "y plane". This value is forcing firingspread to aim more up or more down than weapon is aiming or to even aim firingspread backwards; can be seen with ai2_showfiringspreads=1 |

| 0x124 | 00 00 61 44 | 900.000000 | unknown; it is some angle. If this angle is for example 90°, then AI, which is shooting this weapon, will try to copy target's movements eg. when target strafes left, armed AI stops shooting and runs left too. If you set it 270°, armed AI is performing opposite actions eg. when you run left, armed AI runs right. While running, AI stops shooting. |
| 0x128 | 00 00 20 41 | 10.000000 | Max inaccurancy angle; sets max angle between weapon's aiming vector and target's position. When AI exceeds this angle(by recoil or target running away), AI stops shooting and aims weapon again straight to the target, then resume shooting. |

| 0x130 | 00 00 96 43 | 300.000000 | Weapon sound sphere radius. When somebody shoots, weapon creates this range. AIs which are inside this range notice there was a shot + they know WHO is the shooter and WHERE he stands (threat strong), can be seen with ai2_showsounds=1 (but you have to be in a large open area, since those ranges are quite big) |
| 0x134 | 00 00 40 41 | 12.000000 | Minimal shooting distance; When AI is closer then min.shot.dist., it will stop shooting and attempt to go away from the target until it again reaches higher distance then min.shot.dist. is. You can see its effect when AI is operating SBG and you get too close. |
| 0x138 | 00 00 61 44 | 900.000000 | Maximal shooting distance; When AI is further then max.shot.dist., it isn't shooting but running towards target until it reaches max.shot.dist. limit. Then AI opens fire. You can see its effect when AI is far away and has w2_sap. |
| 0x13C | 05 00 | 5 | unknown; always the same |

| 0x14C | 00 00 34 43 | 180.000000 | Length of firingspread which aims from weapon. When AI collides with this firingspread, it tries to dodge/hide of it. Can be seen by ai2_showfiringspreads=1 (180 for w1_tap, 150 for w2_sap, 120 for w4_psm) |
| 0x150 | 00 00 40 40 | 3.000000 | Lenght of the firingspread's base side. Can be seen by ai2_showfiringspreads=1 |
| 0x154 | 50 77 D6 3D | 0.104719 | angle between firingspread's base and its altitude(length). Can be seen by ai2_showfiringspreads=1 (0.1 for w1_tap, 0.21 for w2_sap) |
- Transform matrix
- Probably defines the orientation, scaling and position of the firing spread. Didn't check.
0x158 - 0x1D7
- SECONDARY FIRING MODE
The only original weapon for which these fields are not all zero is w11_ba1.
They are the exact counterparts of the fields at 0xD8 - 0x157.

- 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.
