Game scheme file
From Worms Knowledge Base
- "WSC" (see worms terminology) redirects here. For the scheme contest, see Worms Scheme Contest.
The W:A scheme file format contains game settings, which define which weapons will be available, various game options such as turn time and weapon strength, as well as many other settings.
Contents
Versioning
The basic W:A scheme format currently has three versions:
- Version 1 is the original scheme format that came with the game. It is 221 bytes in size, and contains only the basic game options and settings for the standard weapons. Much of the information on this version was initially extracted from The Fiddler.
- Version 2 was introduced in the v3.5 Beta 1 Update. It is 297 bytes in size, and contains the above plus settings for super weapons.
- Version 3 was introduced in the v3.8 Update. It is of variable size, depending on how many extended options are set — in 3.8 it can reach up to 407 bytes, though this may be extended in the future without necessarily incrementing the scheme format version. It contains the new Extended Scheme Options introduced in this version of the game. Default values are specified for each of the Extended Scheme Options which are used by the game when the file is not long enough to contain the option in question.
File format
A scheme is organized into the following sections, which are explained in more detail below. Depending on the scheme version, specific sections may not be available.
Offset | Size | Version | Section | Description |
---|---|---|---|---|
00 | 5 | 1 | Header | Signature ("magic bytes") and version of scheme. |
05 | 35 | 1 | Options | Game options like number of rounds, mines, worm energy, etc. |
29 | 180 | 1 | Weapons | Normal weapon and utility table. |
DD | 76 | 2 | Super weapons | Super weapon and utility table. |
129 | 0-110 | 3 | Extended options | Detailed physics / emulation / RubberWorm settings. |
The following data types are used:
- Integers are little endian.
- Fixed-point values can be thought of as being split into two halves; the most significant two bytes are the whole part, and the least significant two bytes are the fractional part, measuring 65536ths. For instance, 0x00020001 (which due to little-endian would be written to the file in the order 01 00 02 00) would equal 2 + 1/65536. However, these two halves really act as one, so can perhaps better be considered as a 32-bit signed integer measuring 65536ths — most notably, both halves of the fixed point take part in twos complement (so 0xFFFFFFFF is -(1/65536) and not -(65535/65536)).
- Bools, unless otherwise specified, use 0 for false and 1 for true.
- Tri-state values have the following possible values: 0 for false, 1 for true, 128 (0x80) for the default behaviour as determined by game engine version or other external factors.

27 | 1 | bool | Team Weapons | If true, teams will start the match with their preselected team weapon. The team weapon setting will override the Ammo, Power, Delay, and Crate settings for the 8 team weapons in the scheme (see Team weapons). |
28 | 1 | bool | Super Weapons | If true, super weapons may appear in weapon crate drops (see Crate probability). |
Weapons
The following weapon settings follow for each individual weapon. Version 1 of the scheme format stores only the 45 regular weapons. Version 2 of the format and later have added support for super weapon settings, totalling to 64 weapon records.
Offset | Size | Type | Name | Description |
---|---|---|---|---|
00 | 1 | uint8 | Ammunition | A value of 10 or between 0x80 and 0xFF will give unlimited ammunition. |
01 | 1 | uint8 | Power | Effect varies depending on weapon. Jet Pack power will set the fuel. |
02 | 1 | uint8 | Delay | A value between 0x80 and 0xFF will give the weapon an unlimited delay, "blocking" it. This is useful if one doesn't want a specific super weapon that has 0 ammunition to appear in crates. |
03 | 1 | uint8 | Probability | Chance of the weapon appearing in a crate. |
The list of weapons, as they appear in the scheme files and in the game memory, is as follows. If the given weapon's power is exceeded, the game warns about "non-standard" power levels, which are only defined for normal weapons, neither utilities nor super weapons.

Extended options
The following options are found only in Version 3 schemes. This section of the scheme file may be extended further in future versions of the game without the scheme version being incremented. For the options which follow, the game will detect invalid values when a scheme is loaded, and reset them to the defaults.
Several of these settings were previously achievable by forcing a specific game logic version or by using RubberWorm commands, and can now be controlled separately.
Offset | Size | Type | Default | Name | Description |
---|---|---|---|---|---|
129 | 4 | 0 | Data Version | Currently 0x00000000. This may be changed by future versions of the game if interpretations of existing settings, for instance superweapon power/crate probability, change. | |
12D | 1 | bool | false | Constant Wind | True if the wind field that follows should be interpreted as the constant value of the wind. |
12E | 2 | sint16 | 100 | Wind | The strength and direction of the wind if Constant Wind is true (positive being rightwards wind, negative being leftwards wind), else the maximum strength of the random wind (negative values inverting the wind bias). |
130 | 1 | uint8 | 15 | Wind Bias | The higher the value, the more likely worms on the right side of the map will get leftwards wind, and vice versa. |
131 | 4 | fixed-point | 15728/65536 0x00003D70 |
Gravity | Acceleration due to gravity in pixels per frame per frame.
|
135 | 4 | fixed-point | 62914/65536 0x0000F5C2 |

|
139 | 1 | uint8 | 255 | Rope Knocking | Rope knocking force in percentage of the ordinary rope knocking force, or 255 to use the value from the channel scheme (online) or registry (offline). Known as "Knock" in RubberWorm. |
13A | 1 | uint8 | 255 | Blood Level | Amount of blood emitted from worms, or 255 to use the value from the channel scheme (online) or the default (offline, 25). Does not affect the blood's colour. |
13B | 1 | bool | false | Unrestrict Rope | If true, the rope may be fired 54 degrees below the horizontal, and has reduced friction. Known as "IR" in RubberWorm. |
13C | 1 | bool | false | Auto-Place Worms by Ally | If true, the game will attempt to group worms by their allied colour when automatic worm placement is enabled (or is forced by the presence of CPU teams). |
13D | 1 | uint8 | 255 | No-Crate Probability | If set to a value other than 255, specifies the probability of no crate falling at the start of a given turn; the maximum allowed to be set ingame being 100 (0x64). If the value is set to 255, this field is ignored and the usual logic for determining the no-crate probability applies (see Crate probability). |
13E | 2 | uint16 | 5 | Maximum Crate Count on Map at Once | Specifies the maximum number of crates which can appear on the map at once before the game will stop spawning new ones. Known as "Cratelimit" in RubberWorm. Setting this too high can cause strange graphical effects. |

146 | 1 | bool | false | Anti-Lock Power | If true, power will start to decrease once it reaches the maximum, instead of the weapon being fired. Intended to make full-power shots more challenging. Known as "ALP" in RubberWorm. |
147 | 1 | bool | false | Worm Selection Doesn't End Hot Seat | If true, selecting worms at the start of a turn will not cause the Hot Seat timer to end and the turn timer to start. |
148 | 1 | bool | false | Worm Selection is Never Cancelled | If true, Worm Selection won't be cancelled by movement, etc.; that is, if Worm Select is enabled in the scheme, you can always press tab during a turn to change worms; or if not, use of the Select Worm weapon will cause Worm Selection to be enabled until the end of the turn. Know as "SWAT" in RubberWorm. |
149 | 1 | bool | false | Batty Rope | If true, worms will keep their ninja rope, bungee, or jetpack even when a turn ends. |
14A | 1 | enum | 0 | Rope-Roll Drops | Determines which, if any, weapons can be dropped while in a rope roll (after detaching the Ninja Rope or Bungee while control is still retained).

15A | 1 | uint8 | 30 | Petrol Touch Decay | To what extent flames from a Petrol Bomb decay when touched by a worm. Larger values will result in the petrol disappearing faster and thus imparting less total damage.
|
15B | 2 | uint16 | 200 | Maximum Flamelet Count | The maximum number of fire objects that can exist at once. Creation of new flamelets beyond this limit will erase older ones. Setting this too high can cause strange graphical effects. Known as "Flames" in RubberWorm.

170 | 1 | bool | true | Angle Cheat Glitch | If true, selecting and firing the baseball bat and longbow while moving makes it possible to bypass the angle restrictions on these weapons. |
171 | 1 | bool | true | Glide Glitch | If true, a certain type of leftward collision by a jumping, post-drilling, or post-retreat worm can cause the worm to continue moving with reduced speed rather than landing. |
172 | 1 | enum | 0 | Skipwalking |
|
173 | 1 | enum | 0 | Block Roofing |
|
174 | 1 | bool | true | Floating Weapon Glitch | If true, a weapon which would normally explode on impact can be dropped onto a surface and sit until its fuse expires, if done in precisely the right way. |

|
188 | 1 | uint8 | 0 | RubberWorm Crate Rate | Sets the number of crates that can potentially spawn simultaneously at the start of the turn. With crate drop probabilities set to 100% and when the maximum crate count would not be reached, this is equal to the number of crates which spawn. A crate counter will also be enabled if this is nonzero. Known as "Craterate" in RubberWorm. |
189 | 1 | bool | false | RubberWorm Crate Shower | If true, crates will drop continuously during turns. Known as "Crateshower" in RubberWorm. |

18F | 1 | bool | false | Fractional Round Timer | If true, the sudden death round timer counts down in fractions of seconds, instead of only in whole seconds. In schemes with one second turn time this allows sudden death to approach even if no players fail to finish their turn before the time runs out. |
190 | 1 | bool | false | Automatic End-of-Turn Retreat | If true, retreat time will be triggered when turn time expires. Useful in "weapon use doesn't end turn" mode. |
191 | 1 | enum | 1 | Health Crates Cure Poison | Determines which worms, if any, are cured of poison when a health crate is collected.
|
192 | 1 | enum | 0 | RubberWorm Kaos Mod | Changes the utility crate probabilities (Fast Walk, Laser Sight, Damage*2, Invisibility, Low Gravity, Crate Spy, Jet Pack, Double Time, Crate Shower) between 6 presets. Known in RubberWorm as "Kaosmod".

|
194 | 1 | bool | false | Conserve Instant Utilities | If true, instant utilities are consumed one at a time, and the remainder conserved, staying in the teams' inventories for later automatic use. Among other effects, this causes Damage*2 ammo to behave like Worms World Party's Double Damage ammo setting. |
195 | 1 | bool | false | Expedite Instant Utilities | If true, instant utilities are always consumed as soon as they are collected, even in circumstances (such as after the end of a team's turn) when they would normally be conserved for later use. |
196 | 1 | uint8 | 1 | Double Time Stack Limit | The number of times a Double Time instant utility can be activated in a single turn. 0 represents unlimited activations. Stacking occurs with multipliers 2*, 3/2*, 4/3*, 5/4*, etc. |
Differences in Worms World Party
Worms World Party schemes are based on Worms Armageddon version 1 schemes. After the weapon settings (which don't include super weapons), Worms World Party schemes contain three bytes of unknown purpose (appear to usually be null), followed by five bytes composed of a repeat of the signature followed by the version one more time. In addition, the Worms World Party schemes use version number 1, and they interpret Double Damage ammo as the number of turns for which double damage will take effect.
