RubberWorm (or wkRubberWorm) is a module for WormKit that can modify parts of the Worms Armageddon physics to create WormPot-like effects, and adapts some features of wkMagic to the 22.214.171.124, 126.96.36.199 and 188.8.131.52 versions. It was originally released by Pisto on 6 April 2008.
RubberWorm's effects are applied to the game when certain scheme settings are set to certain values. These settings are normally unused, such as crate probabilities for superweapons. As such, only an external scheme editor can create schemes that will enable RubberWorm effects, though RubberWorm does also provide a chat command interface allowing a host to enable RubberWorm effects in the lobby of a WormNET game. The scheme can then be extracted from the replay afterwards.
For a complete and trusted online play, all players must run WA through WormKit, and should have the same version of the RubberWorm dll file.

Installation and use
As any WormKit module, it has to be placed with the WormKit files in the W:A main folder, and the game must be run through WormKit.exe instead of WA.exe (the same applies for watching replays of games played with RubberWorm). Changes are applied only when using special schemes with some altered bytes.
Some antivirus programs may treat RubberWorm (as well as Wormkit) as a virus. It is a false alarm: it happens because RubberWorm uses some technique and Dlls abused by malware too.
wkRubberWorm is written in C, and a part of the source code, lacking of addresses and structs (as wkMagic), is public for demonstrative purpose.
There is a 184.108.40.206-compatible RubberWorm version, modified by Kawoosh to work on 220.127.116.11. It has all basic features of old RubberWorm, KaosMod and LaserFix and will not make desyncs when playing with an old WA+RubberWorm user. Read more here.
The original purpose of RubberWorm. Every time a worm hits an object or the terrain (in any direction), it bounces off of it. If it's during a rope roll, it can continue roping, and it never takes fall damage or loses the turn. The feature is always off if the worm is flying for a jump.
The worms' "boing" sound can switched on/off typing in the in-game chat /boing.
- Worm bounciness (or technically, the coefficient of restitution) is determined by the quotient of the value for the Armageddon crate probability divided by 255. For example, if the value is set to 0, the coefficient of restitution is 0, resulting in no bounce. If 255, the coefficient is 1, resulting in a perfectly elastic collision (the worm bounces with the same speed with which it hit the object or terrain).
Gravity can be made stronger or weaker, eliminated or even reversed. When reversed, a worm can stand on its head and shoot, but walking is obviously buggy. Also, should an object encounter no obstacle and fall into the sky, it will be sent to water when it reaches a certain height, otherwise it would block the game indefinitely.
- Activated by the crate probability of the Mail Strike, if the high bit (eighth bit) is clear. The other bits control the strength of gravity, from -64 to +63 in two's complement format (the seventh bit is the sign bit); a value of 0 or 12 results in default gravity.
Central gravity (black hole mode)
Gravity points towards the center of the map, or away from it (anti-gravity). These modes can either be proportional, where gravity is stronger near the center of the map, or constant, where gravity is the same strength for all locations.
In black hole mode, the object may either start a steady orbit or fall in the middle of the map and never stop flying: to avoid the first case objects that don't explode after some seconds (like worms, mines, crates and barrels) have a very small air viscosity value (see below); for the second case, objects nearer than 15 pixel to the center are sent to water.
Anti-gravity has a similar safeguard to reversed gravity (see above).
The strength of the gravity can be adjusted.
- Activated by the crate probability of the Mail Strike. The high bit (eighth bit) enables black hole mode; the seventh bit enables proportional mode; the other bits control the strength of the black hole's gravity, from -32 to +31 in two's complement format (the sixth bit is the sign bit).
Objects flying through the air lose speed up to a steady velocity, determined by gravity and wind (imagine throwing a rock in the water). Some objects, such as crates, graves, barrels, parachuting worms, and Mail Strike letters, will not experience this effect. It is adjustable: a value of 63 makes the air pasty as water.
- Activated by the crate probability of the Concrete Donkey. A higher value produces a stronger effect. If the value is odd, the effect will apply to worms as well as objects.
Like air viscosity, it can be applied to only objects or worms too, but never to those objects (like bazooka) that are already influenced by wind or crates, graves, barrels. How much the wind moves the objects is adjustable.
- Activated by the crate probability of the Suicide Bomber. A higher value produces a stronger effect, with the highest value (255) corresponding to the wind susceptibility of the Bazooka. If the value is odd, the effect will apply to worms as well as objects.
Anti worm sink
If activated, a worm that hits the water is prevented from drowning and instead teleported to the last location where it has been motionless. The turn does not end. If the teleport results in the worm falling and hitting water again (for example, if the terrain has since been destroyed by a weapon), it drowns normally.
- This feature is activated by a non-zero value for the crate probability of the French Sheep Strike.
Arrows point to crates, as they do in certain missions. This feature can give a player an advantage if other players do not have RubberWorm, so a chat message is used to alert other players to its use.
- Type /arrows in the in-game chat to activate this.
Currently, the velocity of a worm is slowed by 4% each frame that a worm slides along the terrain. This is given by multiplying velocity by F*0.01, where the default F value is 96. A lower value results in a higher degree of friction, with F=0 reducing velocity to zero immediately (infinite friction). Values between 96 and 100 give slippier terrains, while a value of 100 results in no friction. Values above 100 will result in the worm's velocity actually increasing as it slides.
- The friction value is stored in the crate probability of the Salvation Army.
Shot doesn't end turn, Loss of control doesn't end turn, Fire doesn't pause timer, Improved rope, Continuous crate shower
To edit these options, start with a value of zero and add the corresponding number for each option you want to enable (listed below). Then set the crate probability of the Mole Squadron to the resulting sum.
Shot doesn't end turn
Firing a weapon doesn't end the player's turn. There's no retreat time and you can't control any weapon (such as Sheep or Supersheep) when turn time runs out.
- Controlled by the first bit of the crate probability of Mole Squadron (add 1 to enable).
Loss of control doesn't end turn
When activated, control of the active worm will not be lost in any circumstances (fall from a great height, weapon explosion, etc) except death.
- Controlled by the second bit of the crate probability of Mole Squadron (add 2 to enable).
Fire doesn't pause timer
The timer doesn't pause while firing any weapon. Useful with Shot doesn't turn, because one could extend his turn time for a very long time using drill or blow torch, for example.
- Controlled by the third bit of the crate probability of Mole Squadron (add 4 to enable).
Changes the rope physics to simulate Worms 2 (higher accelleration, 162 degrees of shooting)
- Controlled by the fourth bit of the crate probability of Mole Squadron (add 8 to enable).
Continuous crate shower
Normally, the game checks between turns the crate probability settings, and determines if and which crate must be spawned. With this feature, you can force the game to do this job every 5 seconds, also during turns. If you want a crate shower like Worms World Party, use SchemeEddy to check that the probability of no crate falling per turn is 0%. Keep in mind that the WWP crate shower spawns a completely random crate, that is it doesn't check the probability of each single weapon (that's why you can grab even Surrender).
- Controlled by the fifth bit of the crate probability of Mole Squadron (add 16 to enable).
- There are many engine version that come with the last update, and some of them may be interesting for their different behaviour. Some users report that this feature doesn't work (sometimes or at all) in network games: if the host sets a particular version, this change is not propagated to the other players, and so the game will end immediatly due to desynch. A 1-player game should work always, anyway.
- Version is set by the crate probability of Select Worm.
No objects speed limit (/version65 or /ts3)
- Teststuff3 (18.104.22.168[teststuff3]) is an old version of teststuff (already available with 22.214.171.124). It is almost the same of the public teststuff5, but it doesn't just double the speed limit, it is removed.
- Activated by a value of 0x41 (65 in decimal notation) of the crate probability of Select Worm.
All objects pushed by explosions (/version78)
- This version (126.96.36.199-19) contains a bug that enables a more realistic behaviour of objects (though it's not always good from the gameplay side): all objects (including grenades, cows, banana, fragments of cluster grenade...) are pushed by an explosion, with a force decreasing with distance from the center of the explosion of course.
Workaround for the lasersight bug (/version79)
- This version (188.8.131.52-21) is the most recent one that doesn't have the lasersight bug, which affects some versions before 184.108.40.206 and can cause desynchronization in online games and replays. WARNING: this engine version does not include the undefined crate contents feature (crate contents choosen when you actually grab them), which is a very strong weapon against cheats. If you are sensible to this problem, consider LaserFix.
Crate rate variability
Controls the number of crates that appear per turn. When a value of Crate Rate exists, the Crate Count automatically will be turned on.
- Set by the crate probability of the Indian Nuclear Test. The value 1 only will turn on the Crate Count
Crate limit variability
Controls the number of crates that can exist on the map at any one time (five at default)
- Set by the crate probability of the Magic Bullet.

Pisto gave up coding RubberWorm, though version 1.0 has been developed inconstantly for over a year. He lost interest in Worms, but also in programming in general. The source code of RubberWorm 0.7 (a version compatible with the old 220.127.116.11 update, much similar to the current version) and of the never going to be 1.0 has been given to Deadcode: his aim is to add the emulation of RubberWorm in the official updates. This is going to happen in the next update after 18.104.22.168.
Pre-release with aliased-bounces
On 26th August 2009 a test build of RubberWorm 1.0 has been released. The reason for sharing it is to show some of the new features, mainly aliased-bounce. It allows to emulate the real behaviour of an object colliding with an object with a slope, a great lack of the Worms Armageddon default engine.
