Weapons file

(Up to File formats)

A weapons file stores Worms 2 weapon options. Unlike other games, this file does not also contain game options; those are stored in a separate file.

As in traditional Worms 2 fashion, most of the values which could be stored within one byte are stored within four. All types are little-endian. How many of these are actually read has not been tested.

Reverse engineered by Muzer, so there might be mistakes ;)

Header

Offset	Size	Type	Description
00	0x10	Unknown	16 bytes of unknown purpose. Appears to change every time you save it even if nothing in the file is changed and I can see no pattern myself.
10	8	char[8]	Magic number used to identify the weapons file. The string "WEPFILE", but null-terminated (unlike the one in the options file). Which is good because it means the whole file is now nicely aligned (compared to the options file at least).

Weapons

Each weapon appears to be 140 bytes long, and they appear to be directly concatenated together. Fields which do not apply to that weapon appear to be populated with 0xe0e0e0e0. The offsets are now relative to the start of that weapon (0x18 for the bazooka, etc.).

Offset	Size	Type	Description
00	4	sint32	Initial stock of weapon. 0x0a (10) is infinite.
04	4	sint32	Delay of weapon.
08	4	sint32	Retreat time after using weapon. 0 for scheme default.
0C	4	sint32	Nonzero if the weapon is remembered (automatically equipped the next time that worm takes a turn).
10	4	sint32	Not used in any weapon.
14	4	sint32	Total ammo found in a crate.
18	4	sint32	Bullet count (in a single shot).
1C	4	sint32	Appears in crates (crate probability), measured in percent.
20	4	sint32	Weapon damage, measured in health points. Also determines blast radius.
24	4	sint32	Blast power, measured in percent. Pushing power of the weapon.
28	4	sint32	Explosion Bias, measured in percent.
2C	4	sint32	Homing delay, measured in milliseconds.
30	4	sint32	Homing time, measured in milliseconds.
34	4	sint32	Wind response, measured in percent.
38	4	sint32	Not used in any weapon.
3C	4	sint32	Number of clusters.
40	4	sint32	Cluster throw power, measured in percent.
44	4	sint32	Cluster throw angle, measured in degrees.
48	4	sint32	Cluster damage, measured in health points. Also determines blast radius.
4C	4	sint32	Override fuse, measured in seconds, 0 for default.
50	4	sint32	Amount of fire, measured in percent.
54	4	sint32	Fire spread speed, measured in percent.
58	4	sint32	Fire period, measured in percent (the time it burns for).
5C	4	sint32	Melee impact force, measured in percent.
60	4	sint32	Melee impact angle, measured in degrees.
64	4	sint32	Melee impact damage, measured in health points.
68	4	sint32	Fire Punch jump height, measured in percent.
6C	4	sint32	Dragon Ball damage, measured in health points.
70	4	sint32	Dragon Ball impact power, measured in percent.
74	4	sint32	Dragon Ball impact angle, measured in degrees.
78	4	sint32	Dragon Ball impact time, measured in milliseconds.
7C	4	sint32	Kamikaze and digging tools dig time, measured in milliseconds.
80	4	sint32	Number of strike bomblets.
84	4	sint32	Strike bomblet damage, measured in health points. Also determines blast radius.
88	4	sint32	Bullet spread, measured in degrees.

Here is the order in which the weapons appear. Note that superweapons do not appear in the file and so cannot be edited, even externally.
