(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.
