'''RubberWorm''' (aka wkRubberWorm) is a module for [[WormKit]] that can alter parts of the Worms Armageddon physics, and adapts some features of [[wkMagic]] to the last update of the game (3.6.28.0).
+
'''RubberWorm''' (also known as '''wkRubberWorm''' or simply '''RW''' in [[Terminology|worms terminology]]) was a module for [[WormKit]] that could modify parts of the ''[[Worms Armageddon]]'' physics to create [[Wormpot]]-like effects, and adapted some features of [[wkMagic Map Wizard|wkMagic]] to the 3.6.29.0, 3.6.30.0, 3.6.31.0, 3.7.0.0 and 3.7.2.1 versions. It was originally released by [[Pisto]] on 6 April 2008, and then ported by [[People/Kawoosh|Kawoosh]] to the latest W:A update with several [[RubberWorm/Download|new features]].
  
−
= General Info =
+
Starting with the [[Worms_Armageddon_ReadMe_(English)/v3.8_Update|version 3.8]] of W:A, all of RubberWorm's features have been integrated into the base game as [[Game_scheme_file#Extended_options|extended scheme options]], which makes the module obsolete.
  
−
== Installation ==
+
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.
  
−
As any Wormkit module, it has to be placed with the Wormkit files in the W:A main folder, and Wormkit.exe has to be run instead of WA.exe. Changes are applied only when using special schemes with some altered bytes.
+
For a complete and safe online play, all players should have the same version of the RubberWorm dll file.
  
−
== Network play ==
+
== General Info ==
  
−
Each modification is activated by some bytes in the scheme file (for letting net-play between clients with the module and without). Those bytes (crate probability of some super-weapons) are unused by W:A.
+
=== Installation and use ===
−
All the players in a network game with any of the feature of RubberWorm active must have the same version of the dll or they are likely to desynchronize quickly, because there's no backward compatibility system.
+
  
−
== Antivirus issue ==
+
Like any WormKit module, it has to be placed in the W:A main folder (or you can use the installer), and you need to enable Loading of WormKit modules in the W:A's Advanced Settings. Changes to the game are applied only when any feature of RubberWorm is enabled.
  
−
Some antiviruses program may threat 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.
+
=== Source code ===
  
−
== Scheme settings ==
+
Original wkRubberWorm is written in C, and a part of the source code, lacking addresses and structs (like [[wkMagic]]), is public for demonstrative purposes.
 +
RubberWorm3x by [[People/Kawoosh|Kawoosh]] was done by reverse-engineering the original RubberWorm, rewritten in C++.
  
−
A detailed explanation about how to set up a scheme to trigger the features is in the readme that comes with the wkRubberWorm archive: it's impossible to edit those hidden value with the built-in editor of W:A, you need an external editor like [[SchemeEddy]].
+
=== Kawoosh's version of RubberWorm ===
−
In the same package there are some schemes ready to play.
+
  
−
= Features =
+
Since 3.6.30.0, [[People/Kawoosh|Kawoosh]] had been updating RubberWorm with new features and support for newest W:A updates. It had all basic features of old RubberWorm, KaosMod, TrastulloPerAtrox and some of LaserFix and will not make desynchronizations when playing with an older WA+RubberWorm user'''<nowiki>*</nowiki>'''. The same concerns replays—you can safely view older RubberWorm replays (made before 3.6.30.0) using this version. Read more [http://forum.team17.com/showthread.php?p=734952#post734952 here]{{dead link}}.
  
−
== Worm that bounce ==
+
'''<nowiki>*</nowiki>'''If none of the new features, listed [[RubberWorm/Download|here]], are enabled. Some of them were also part of the old LaserFix module, and thus they are compatible. 3.6.29.0 version users cannot play against 3.7.0.0 online, but replays files are compatible with minor issues.
  
−
The first 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 get fall damage or lose the turn.
+
Features added by Kawoosh can be seen on the [[RubberWorm/Download|download page]].
−
The feature is always off if the worm is flying for a jump.
+
−
"How much" do the worm bounce can be set.
+
  
−
== Gravity modifications ==
+
== Features ==
  
−
=== Normal gravity ===
+
=== Bouncing worms ===
 +
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.
  
−
Gravity can be made stronger or weaker, eliminated or even reversed (objects fall to the roof). In the last case, a worm can stand on its head and shoot, but walking is obviously buggy; if an object encounters no obstacle and flies into the sky, when it reaches a certain heigth it's sent to water, because otherwise it would block the game indefinitely.
+
The worms' "boing" sound can switched on/off typing in the in-game chat /boing (not in RubberWorm3x).
 +
: ''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).''
  
−
=== Central gravity ===
+
=== Gravity modifications ===
 +
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 −63 to +63 in one's complement format (the seventh bit is the sign bit); a value of 0 or 12 results in default gravity. The value is one's complement in order to make it possible to set zero gravity; to do this, you make the gravity "negative zero" (which is −1 in two's complement), ie 0x7F''
 +
 
 +
=== 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.
  
−
Aka black hole mode. Gravity points to the center of the map, or outside from it (centrifugal gravity). Both these modes can be proportional or costant gravity: the first means that the gravity force is stronger near the middle of the map, the second means the distance from the center doesn't matter, gravity is the same for all objects.
 
 
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.
 
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.
−
In centrifugal mode instead, to avoid infinite flying there's something like what happens with reversed gravity.
 
−
The strength of the gravity can be set.
 
  
−
== Air viscosity ==
+
Anti-gravity has a similar safeguard to reversed gravity (see above).
  
−
Objects moving in air lose speed up to a steady velocity, determined by gravity and wind (imagine throwing a rock in the water). This sort of friction is applied to only objects or worms too, but never to objects that already have this viscosity value (such as parachuting worms or a letters of the mail strike) or crates, graves and barrels. It is adjustable: a value of 63 makes the air pasty as water.
+
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).''
  
−
== Wind influence ==
+
=== Air viscosity ===
 +
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.''
  
 +
=== Wind influence ===
 
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.
 
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'''.''
 +
 +
=== Crate finder ===
 +
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.''
 +
 +
=== Friction modifications ===
 +
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 without it 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).''
 +
 +
==== Improved rope ====
 +
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).''
 +
 +
 +
=== Version override ===
 +
: There are many engine version that come with the last update, and some of them may be interesting for their different behaviour. You shouldn't emulate the earliest versions of the 3.x, as they may lead to crashes (like, for not supporting the new scheme format, colored/big maps).
 +
:: ''Version is set by the crate probability of '''Select Worm'''.''
 +
 +
For version numbers, see [[WA versions list]].
 +
 +
=== 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'''.''
 +
 +
== Chat command interface ==
 +
 +
These commands can be used in the host/join lobby. Omitting the parameter either activates the feature with a default value, or sets it off.

 +
On 26th August 2009 a test build of RubberWorm 1.0 was [http://forum.team17.com/showthread.php?t=39403 released]. The reason for sharing it is to show some of the new features, mainly anti-aliased bouncing. It allows to emulate the real behaviour of an object colliding with a slope, a missing feature of the ''Worms Armageddon'' default engine.
  
−
If activated, worms that are going to sink are teleported, without losing the turn, to the last position where it has stood at least for a moment. If, after being teleported, the worm can't stand again somewhere and falls again into water (for example, if the terrain has been destructed by a weapon), it drowns normally.

RubberWorm (also known as wkRubberWorm or simply RW in worms terminology) was a module for WormKit that could modify parts of the Worms Armageddon physics to create Wormpot-like effects, and adapted some features of wkMagic to the 3.6.29.0, 3.6.30.0, 3.6.31.0, 3.7.0.0 and 3.7.2.1 versions. It was originally released by Pisto on 6 April 2008, and then ported by Kawoosh to the latest W:A update with several new features.

Starting with the version 3.8 of W:A, all of RubberWorm's features have been integrated into the base game as extended scheme options, which makes the module obsolete.

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 safe online play, all players should have the same version of the RubberWorm dll file.

General Info

Installation and use

Like any WormKit module, it has to be placed in the W:A main folder (or you can use the installer), and you need to enable Loading of WormKit modules in the W:A's Advanced Settings. Changes to the game are applied only when any feature of RubberWorm is enabled.

Source code

Original wkRubberWorm is written in C, and a part of the source code, lacking addresses and structs (like wkMagic), is public for demonstrative purposes. RubberWorm3x by Kawoosh was done by reverse-engineering the original RubberWorm, rewritten in C++.

Kawoosh's version of RubberWorm

Since 3.6.30.0, Kawoosh had been updating RubberWorm with new features and support for newest W:A updates. It had all basic features of old RubberWorm, KaosMod, TrastulloPerAtrox and some of LaserFix and will not make desynchronizations when playing with an older WA+RubberWorm user*. The same concerns replays—you can safely view older RubberWorm replays (made before 3.6.30.0) using this version. Read more here[dead link].

*If none of the new features, listed here, are enabled. Some of them were also part of the old LaserFix module, and thus they are compatible. 3.6.29.0 version users cannot play against 3.7.0.0 online, but replays files are compatible with minor issues.

Features added by Kawoosh can be seen on the download page.

Features

Bouncing worms

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 (not in RubberWorm3x).

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 modifications

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 −63 to +63 in one's complement format (the seventh bit is the sign bit); a value of 0 or 12 results in default gravity. The value is one's complement in order to make it possible to set zero gravity; to do this, you make the gravity "negative zero" (which is −1 in two's complement), ie 0x7F

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).

Air viscosity

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.

Wind influence

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.

Crate finder

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.

Friction modifications

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 without it 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).

Improved rope

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).


Version override

There are many engine version that come with the last update, and some of them may be interesting for their different behaviour. You shouldn't emulate the earliest versions of the 3.x, as they may lead to crashes (like, for not supporting the new scheme format, colored/big maps).
Version is set by the crate probability of Select Worm.

For version numbers, see WA versions list.

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.

Anti-aliased bounces

On 26th August 2009 a test build of RubberWorm 1.0 was released. The reason for sharing it is to show some of the new features, mainly anti-aliased bouncing. It allows to emulate the real behaviour of an object colliding with a slope, a missing feature of the Worms Armageddon default engine.

Future plans

Pisto gave up coding RubberWorm, though version 1.0 had been developed inconstantly for over a year. He lost interest in Worms, but also in programming in general.

The source code of Kawoosh's RubberWorm31 0.0.1.17, RubberWorm 0.7 (a version compatible with the old 3.6.28.0 update), and of the never going to be 1.0 were given to Deadcode.

RubberWorm is now part of the base game as of W:A version 3.8.
