Project X/Weapon file block

A weapon block describes of what kind a weapon is, how it reacts, its physical parameters, how much initial ammunition is available and much more. Because of the many different weapon types, different sub-blocks have to be read depending on the type. However, the "header" is always the same, being explained at first, and following the other sub-blocks. If not further explained, data at offsets not listed is empty (0-bytes).

Header

Each weapon block has a small header and a checksum (which isn't actually checked, so it can be anything).

Offset	Size	Type	Description	Default value	Remarks
0	4	int	Identification	0x5ABBDD06	Magic bytes identifying the weapon block, thus they are always the same.
4	8	long	Checksum		Generation unknown, can be anything, not checked by Project X.

General Settings

Following the header are some general settings (mostly configured in the first window of the Project X Weapon Editor). Additional settings follow at the byte at offset 500, and before this are weapon type specific sub-blocks found (so there's space between the first group of settings and the second group, used differently for each weapon type).

Offset	Size	Type	Description	Default value	Remarks
12	1	byte	Table Row		Row of the weapon table in which the weapon will appear. 0 = Utility row, max. is 12.
13	4	bool	Remembered		If true, the weapon will be automatically selected for the next shot after the first one.
17	4	bool	Usable in cavern		Useful to disable airstrikes on cavern maps.
21	4	int	Shoots		The number of shoots which can be done before the turn ends.
25	4	bool	Shoot ends turn		If true, retreat time is started after the weapon has been fired.
29	4	int	Retreat time		The retreat time in millseconds after the weapon has been fired (and shoot ends turn is true).
33	4	int	"Unknown"
37	4	int	Crate Chance		The chance that this weapon will appear in crates. This is shared between all weapons, so using a percentage value from 0-100 is a good idea rather than using any value up to 2^16.
41	4	int	Count in Crate		The additonal ammunition a team will get when collecting a crate with this weapon in it, normally 1.
45	4	bool	Unknown Setting		This boolean is randomly set by Project X, but the meaning has not yet been discovered.
49	4	int	Activation by		Sets the activation type this weapon has. The following values are valid: 0x00: None 0x01: Crosshair 0x02: Throw 0x03: Airstrike 0x04: Spacebar
53	4	int	Activation flag		If the activation type is "Throw", this tells how many weapons are released as herding. If the activation type is "Airstrike", this specifies the subtype (whatever that is). If the activation type is "Space", this specifies the action caused (more information about the parameters of these actions is found below): 0x00: None 0x01: Fire punch 0x02: Baseball bat 0x03: Dragon ball 0x04: Kamikaze 0x05: Suicide bomber 0x06: Ninja rope 0x07: Bungee 0x08: Pneumatic drill 0x09: Prod 0x0A: Teleport 0x0B: Blowtorch 0x0C: Parachute 0x0D: Surrender 0x0E: Skip go 0x0F: Select worm 0x10: Nuclear test 0x11: Girder 0x12: Battle axe 0x13: Utility 0x14: Freeze 0x15: Earthquake 0x16: Scales of justice 0x17: Jet pack 0x18: Armageddon Otherwise, it has no meaning.
57	4	int	Weapon Style		If the activation type is "None", this int has no meaning. If the activation type is "Crosshair", the following styles are available: 0x00: None 0x01: Flamethrower 0x02: Gun 0x03: Launcher 0x04: Bow If the activation type is "Throw", the following styles are available: 0x00: None 0x01: Mine 0x02: Launcher 0x03: Canister If the activation type is "Airstrike" or "Space", this int does not exist and the offset is already used for other information (s. below).
468	4	bool	Custom count		If true, the start ammunition overrides the ones defined in the used WSC scheme. This is only required for the first table as the weapons in the second table always use the following count.
472	4	int	Count		The start ammunition of this weapon.
476	4	int	Unknown setting		Probably has to do with the appearance.
480	4	int	Weapon sprite
484	diff.	string	Long weapon name	None
diff.	diff.	string	Short weapon name	None
diff.	diff.	string	Grid IMG	hi/bazooka.img	The image of the weapon to be displayed in its table cell. hi/... references images in the sprite directory of Worms. Otherwise, a filename in the scheme or any attached library can be used, like "omgwtfbbq.png".
diff.	24	byte[]	Unused bytes
diff.	4	bool	Custom delay		True to override the WSC delay of weapons in the first weapon table. Not required for any additional table.
diff.	4	int	Delay		The number of turns which have to be completed by each team before this weapon becomes available.
diff.	1	bool	Use from library		True to use the weapon block as specified in the library with the following name. Renders other settings of this weapon block useless. The following two strings "Library name" and "Library weapon name" do not exist if this bool is false.
diff.	diff.	string	Library name		The name of the library from which the weapon block with the following name should be used. This string does not exist if "Use from library" is false.
diff.	diff.	string	Library weapon name		The name of the weapon in the library with the name specified above. This string does not exist if "Use from library" is false.
diff.	diff.	string	Aim sprite name even
diff.	diff.	string	Aim sprite name uphill
diff.	diff.	string	Aim sprite name downhill
diff.	diff.	string	Pick sprite name even
diff.	diff.	string	Pick sprite name uphill
diff.	diff.	string	Pick sprite name downhill
diff.	diff.	string	Fire sprite name even
diff.	diff.	string	Fire sprite name uphill
diff.	diff.	string	Fire sprite name downhill
diff.	1	bool	Custom aim sprite		True to use the custom aim sprite names.
diff.	1	bool	Custom pick sprite		True to use the custom pick sprite names.
diff.	1	bool	Custom fire sprite		True to use the custom fire sprite names.
diff.	1	bool	Utility		True if this weapon appears at the bottom right above the wind indicator if activated.
