# Warzone 2100 - AI scripting language manual

## Introduction

In order for Warzone scripts to function properly two files are required: a file with a .slo extension and a file with a .vlo extension.

A .slo file is the main part of the script and holds executable instructions while the .vlo file holds additional variable declarations necessary for the .slo file to function properly.

It is common for a script to deal with new or existing game components such as research topics, structures, unit bodies, propulsions, weapons etc. All these components are defined in appropriate text files like body.txt, structure.txt etc. If you want to use any of these components in your script - in your .slo file - like for example if you want to place certain structures on the map using scripts or enable certain research, you must first make these components available to your script by defining them in a .vlo file.

Roughly said a .slo file is equivalent to a ".c" file and .vlo to a header file in C/C++.

Specific skirmish/multiplayer notes:

Some of the file below does not apply to skirmish scripts! Make your changes to player0.slo and vlo -> player7.slo and vlo.

### Comments

There are two type of comment for the script language. A multi-line comment is started by the characters /* and finishes with */. A single line comment is started by //.

### Vlo files

When writing a script it is usually known what data (as defined in data .txt files, located in 'stats' folder) will be used in the script, so it is a good idea to start writing the script with a .vlo file.

Vlo files are structured as follows:

    script "myScript.slo"

    run

    {

     <variable_definitions>

    }

In the first line a .slo file is attached to this particular .vlo file. variable_definitions that resides inside the curly braces is the heart of every .vlo file, it contains definitions of the data that will be used in the main script part - the .slo file. Each variable definition starts on a new line and is structured as follows:

    <variable_name> <variable_type> <variable_value>

NOTE: Available data types are covered later.

For example if you want to have access to certain droid bodies, like "Python" in your script you have to define it in your .vlo file and assign it to a variable of type BODY with some descriptive name, like:

    myPythonBody BODY "Body11ABT"

"Body11ABT" is an internal name of the "Python" body used by warzone, it is defined in the body.txt file. Since it is a string it must be put inside quotation marks. All components, be it some research, structure, droid template or a weapon is referred by its internal name in the game and are defined in the appropriate txt data files.

Each variable definition in a .vlo file starts on the new line and ends at the end of the line.

It is also possible to define arrays of some data type. For example if you want to use the following 3 research topics in your script you might want to define them like this:

    myResearch[0] RESEARCHSTAt "R-Vehicle-Body11"

    myResearch[1] RESEARCHSTAt "R-Vehicle-Prop-Tracks"

    myResearch[2] RESEARCHSTAt "R-Vehicle-Prop-Hover"

This defines an array of size 3 of type RESEARCHSTAT.

### Slo files

As already mentioned .slo file is the heart of every script, it is the place for the executable code. Slo files can be devided into 3 main parts:

1. Variable declarations
2. Event and function declaration
3. Executable code

Variables used throughout the script are defined in the Variable declarations part, with exception of the local variables, which are explained later.

For the .slo file to be able to access variables declared in the .vlo file they must be declared as public variables in the corresponding .slo file.

Coming back to the two examples above you will have to add following lines to the .slo file:

    public BODy myPythonBody;

    public RESEARCHSTAT myResearch[3];

Keyword `public` signals that the variable is defined in the corresponding .vlo files. Note that unlike in .vlo files variable declarations in .slo files end with a semicolon and unlike in .vlo files it is possible to declare more than one variable of the same type at once.

More generally a variable declaration in a .slo file looks like this:

    <storage> <variable_type> <variable_name1> [, <variable_name2>, ...];

`storage` is one of `public` or `private`. `public` means that the variable is declared and defined in the corresponding .vlo file. `private` means the value is only used in the .slo file. Unlike local variables public and private variables are global variables that can be access from anywhere in the .slo file.

NOTE: All variables are initialized to their default values when created. STRUCTURE/DROID/FEATURE variables are initialized to NULLOBJECT, STRINGs to "", FLOATs to 0.0, INTs to 0, BOOLs to FALSE etc.

back to top

### Event/trigger concept

In Warzone 2100 scripts executable code consists of events. An event is a list of instructions activated by some trigger attached to it. Event defines what to do, a trigger defines when to run an event, i. e. when to execute the code inside an event.

All events are structured as follows:

    event <event_name>(<trigger>)

    {

     <code>

    }

Example:

    event myFirstEvent(every, 50)

    {

     console("Hello world!");

    }

This piece of code will output "Hello world!" to the game console every 5 seconds. Note that triggers are put inside the round braces after the event name while code that is to be executed resides inside the curly braces. The syntax of the executable code is very close to the C/C++ syntax.

The only difference between a WZ event and a function as used in programming languages like C/C++ is that an event is not called or activated by another function, but rather by a trigger attached to it.

It is always possible to interrupt execution of an event with the `exit` keyword, which is a counterpart of the `return` keyword used for functions; `exit` keyword does not deactivate an event.

Example:

    event myEvent(every, 10) //run every second

    {

     console ("this text will be printed every second");

     if((gameTime / 10) > 60) //did more than a minute pass?

            {

             exit; //anything that comes after 'exit' will not be executed

             console("this text will only get printed in the first");

            }

    }

Events must be defined before they can be referenced. If event definition comes after the place where this event is referenced it is necessary to declare this event beforehand in the event and function declaration section.

Events are declared like this:

    event <event_name>;

Such a declaration reserves identifier used as event name.

Example:

    event myEvent; //declaration of the event

    ...

    // another event that references myEvent

    event anotherEvent(wait, 10)

    {

     setEventTrigger(myEvent, inactive); //deactivate myEvent

    }

    ...

    // myEvent is defined after being referenced by anotherEvent,

    // but it works, since we declared myEvent beforehand

    event myEvent(wait, 20)

    {

     console("It all compiles, because I was declared beforehand!");

    }

If myEvent was not declared before being referenced by anotherEvent then this example would not compile.

back to top

### Triggers

In Warzone 2100 triggers are usually simple timers that repeatedly trigger execution of events, but triggers can also be callbacks (special events that occur in the game, like destruction of a building) that are listed and explained later.

Here are available trigger types:

Trigger type | Effect
`wait, <time>` | Run the event after delay `<time>`.
`every, <time>` | Run the event at every `<time>` interval.
`<callback>` | Run when `callback` occurs.
`<bool exp>, <time>` | Run the event if `<bool exp>` is true, checking every `<time>` interval.
`init` | Run the event when the script starts.
`inactive` | Do not run the event until a trigger is assigned to it.

NOTE: All time intervals are in 1/10 of a second.

For example `every, 10` will trigger every second while `wait, 50` will only activate once: 5 seconds after the game has started. If an event has `inactive` assigned as a trigger this event will never execute unless its trigger is reassigned by some other event with `setEventTrigger(<event>, <trigger>)` function.

NOTE: Complete function and callback listings are given below.

A few examples:

    // 1. output text to game console every second

    event everySecond(every, 10)

    {

     console("The game has started " + gameTime/10 + " seconds ago");

    }

    // 2. Code inside this event will never execute unless its event is reassigned later

    event inactiveEvent(inactive)

    {

     console("Someone has just reactivated me!");

    }

    // 3. CALL_NEWDROID callback with parameters

    event droidBuilt(CALL_NEWDROID, 5, ref newDroid, ref myFactory)

    {

     console("We got a new droid at coordinates " &

             newDroid.x & "-" & newDroid.y);

    }

In the last example `droidBuilt` event will be triggered everytime a factory belonging to player 5 produces a new droid. `newDroid` variable refers to the new droid that was just built and `myFactory` to the factory that build this droid. This example assumes that `newDroid` and `myFactory` were correctly defined in the variable declarations section. For more callbacks see Script function callbacks.

NOTE: `ref` keyword means that a pointer to the provided variable is passed to the interpreter, so that a callback can modify value of the variable.

It is possible to reuse a trigger for more than one event if a trigger is declared in the event and function declaration. Trigger declaration has following syntax:

    trigger <trigger_name> (<trigger>);

Example:

    trigger everySecond (every, 10); //trigger declaration

    ...

    event eventOne(everySecond) // uses the trigger we declared above

    {

     ...

    }

    event eventTwo(everySecond) // uses the trigger we declared above

    {

     ...

    }

In this example `everySecond` trigger is defined outside of an event. Such a trigger can be reused by its name. Note that trigger declaration ends with a semicolon.

## Expressions

### String expressions

Strings are put inside quotation marks: `"some text inside quotation marks is a legal string"`.

Strings can be easily concatenated using the `&` operator.

For example: `"String1" & "String2"` will result in "String1String2".

Strings can be compared using `==` operator (case insensitive comparison) or `strcmp()` function.

Such data types as integers, booleans and floats are automatically converted to strings when it is required, so given the following variable declaration:

    private float pi;

    private int myInteger;

    private string myString;

    private bool myBool;

The following line is a valid string expression:

    console("value of pi is " & pi & ", value of myInteger is " & myInteger & ",

    value of myString is " & myString & ", value of myBool is " & myBool);

back to top

### Numeric expressions

Numeric expressions are made up of int variables, numeric constants and functions that return int values, e. g.:

    power * 32 - basePower

    numDroids(player) + 5

The possible operators are: `+` `-` `*` `/`

Increment and decrement operators can only be applied to the integer variables outside of the expression context:

    myInteger++;

    myInteger--;

There are also a number of operators that compare numeric expressions to give a boolean

Operator | Meaning
`<` | Less than
`>` | Greater than
`<=` | Less than or equal
`>=` | Greater than or equal
`==` | Equal
`!=` | Not equal

back to top

### Boolean expressions

Boolean expressions are made up of bool variables, the boolean constants TRUE and FALSE and game functions that return a boolean value e.g.:

    not droidSeen and attackDroid

The possible operators are:

Operator | Meaning
`bool1 and bool2` | True if `bool1` and `bool2` are true
`bool1 or bool2` | True if at least one of `bool1` and `bool2` is true
`not bool1` | True becomes false and false becomes true
`==` | Can also be used with user defined type variables
`!=` | Can also be used with user defined type variables

back to top

### Floating point expressions

Floating point expressions are very similar to integer expressions. There are some differences though: it is not possible to use increment/decrement operators with floating point variables. The integral and fractional parts of the float constant must be separated by a dot, even if fractional part is 0.

Examples:

    myFloat = 1.0 + pi / 2.0 + 3.6;

Floating point expressions cannot be mixed with integer or boolean expressions. To use integers or booleans in floating point expressions they must be cast to FLOATs first.

For more information about casts refer to casts.

## Assignment

The value of a variable or an expression can be assigned to another using the = character, e.g.:

    currentDroid = foundDroid;

    index = base + found * 4;

    myString = "some text";

    myFloat = 2.0 + pi / 2.0;

back to top

## If statements

If statements are used to control which bits of code are executed. The simplest form is:

    if (<bool exp>)

    {

     <code>

    }

In this form if `<bool exp>` evaluates to true then the script code `<code>` is executed, otherwise the code is ignored.

Examples:

    if (<bool exp>)

    {

     <code>

    }

    else

    {

     <other code>

    }

    if (<bool exp>)

    {

     <code>

    }

    else if (<other bool exp>)

    {

     <other code>

    }

    else

    {

     <yet another code>

    }

back to top

## While statements

While statements allow `<code>` to be executed while `<bool exp>` evaluates to TRUE:

    while (<bool exp>)

    {

     <code>

    }

back to top

## Casts

Casts convert one data type into a different one. In Warzone 2100 casts are mostly used to convert float to int, int to float and bool to float. To perform a cast write the required data type in pare nothesis.

Examples:

    myFloat = (float)myInteger + 2.3 + (float)500 + 500.0;

    myInteger = 100 + numPlayers + (int)myFloat;

NOTE: Both `(float)500` and `500.0` represent the same value. When converting FLOATs to INTs fractional part is discarded.

back to top

## Custom functions

It is possible to define custom script functions to reuse certain functionality throughout the script.

Functions have following syntax:

    function <return type> <function name> ([ <argument type> < argument name>, ... ])

    {

     <code>

     return ... ;

    }

Examples:

    function void displayVictoryMessage(int winner)

    {

     console ("Player " & getPlayerName(winner) & " has won the game");

    }

    function float calculateMinimum (float f1, float f2)

    {

     if (f1 < f2)

     {

      return f1;

     }

     return f2;

    }

Functions look almost identical to their C counterparts, except that the beginning of a function is marked with `function` keyword.

It is possible to declare functions like with events it is done in the event and function declaration section:

    function void displayVictoryMessage(int winner);

    function float calculateMinimum (float f1, float f2);

Declared this way it is possible to use a function before it is defined later in the script. To call a function simply provide its name with parameters in pare nothesis:

    displayVictoryMessage(0);

    ...

    console("Minimum of 2 and 2.1 is " & calculateMinimum(2.0, 2.1));

Like in C `return <return expression>;` or for void functions just `return;` returns execution to the caller.

back to top

## Local variables

Local variables belong either to a function or event where they were declared and are not accessible outside of it. Local variables must be declared at the beginning of the function or event. Like public/private variables local variables of the same type can be declared on the same line separated by a comma.

Declaration of a local variable looks as follows:

    local <variable type> <variable name> [, <variablename>, ...] ;

Example:

    event myEvent(myTrigger)

    {

     local int count;

     <code>

    }

    function void myFunction()

    {

     local DROID myDroid1, myDroid2;

     local string myString;

     <code>

    }

back to top

## Macros

The Warzone 2100 Scripting language supports nested macros (current max. depth is 10). Parametrized macros are not supported. Macros are defined as follows:

    #define <macro name> <macro body>

Example:

    #define pi 3.14

Example of a nested macro:

    #define CURRENT_PLAYER 0

    #define CURRENT_PLAYER_NAMe getPlayerName(CURRENT_PLAYER)

During the compilation process macro names are replaced with the actual code.

If any other text but "define" follows after # character then anything between # and end of the line is ignored by compiler making it possible to use #region and other tags in your favorite IDE.

NOTE: "#include" is reserved but not fully supported yet.

## Data types

Apart from standard data types like string (string), integer (int), boolean (bool) and floating point (float) there are some Warzone 2100-specific data types available:

Data type | Meaning
`INTMESSAGE` | Simple. Name of a message as defined in Messages.txt, used mostly for campaign. In most cases it is easier to use a string instead.
`BASEOBJ` | Complex. Any of a DROID, FEATURE or STRUCTURE. It is a pointer to some droid/feature/structure on the map, can be NULLOBJECT if it was not assigned to a particular droid/feature/structure. You have access to the following variables: `baseobj.x` `baseobj.y` `baseobj.z` `baseobj.id` - unique ID number `baseobj.player` - player ID `baseobj.type` - one of OBJ_DROID, OBJ_STRUCTURE, OBJ_FEATURE `baseobj.health` - %age number of body points left `baseobj.clusterID` - the cluster the object is a member of `baseobj.target` - target of the object (in case of a multi-turret object returns target of the default weapon)
`DROID` | Complex. Defined by the ID got from the world editor. It is a pointer to a particular droid on the map, can be NULLOBJECT when no droid is assigned to the DROID variable. You have access to following variables: `droid.x` `droid.y` `droid.z` `droid.id` - unique ID number `droid.player` - player ID `droid.type` - one of OBJ_DROID, OBJ_STRUCTURE, OBJ_FEATURE `droid.health` - %age number of body points left `droid.clusterID` - the cluster the object is a member of `droid.target` - target of the object (in case of a multi-turret object returns target of the default weapon) `droid.order` - current order of the droid `droid.orderx` - target location of the droid order `droid.ordery` - target location of the droid order `droid.action` - current action of the droid `droid.body` - the BODY of the droid `droid.propulsion` - the PROPULSION of the droid `droid.weapon` - the WEAPON of the droid DROIDID - (simple) literally just an Id of a droid `droid.selected` - holds TRUE if droid is currently selected `droid.group` - the GROUP droid belongs to
`FEATURE` | Complex. Defined by the ID got from the world editor. It is a pointer to a map decoration, like a tree, wrecked building, oil resource etc, can be NULLOBJECT. You have access to following variables: `feature.x` `feature.y` `feature.z` `feature.id` - unique ID number `feature.player` - player ID `feature.type` - one of OBJ_DROID, OBJ_STRUCTURE, OBJ_FEATURE `feature.health` - %age number of body points left `feature.clusterID` - the cluster the object is a member of `feature.target` - target of the object (in case of a multi-turret object returns target of the default weapon)
`FEATURESTAT` | Simple. Type of a feature as defined in features.txt.
`TEMPLATE` | Simple. Name of a template as defined in templates.txt.
`STRUCTURE` | Complex. Defined by the ID got from the world editor. It is a pointer to a particular structure on the map, can be NULLOBJECT when no structure is assigned to the STRUCTURE variable. You have access to the foillowing variables: `structure.x` `structure.y` `structure.z` `structure.id` - unique ID number `structure.player` - player ID `structure.type` - one of OBJ_DROID, OBJ_STRUCTURE, OBJ_FEATURE `structure.health` - %age number of body points left `structure.clusterID` - the cluster the object is a member of `structure.target` - target of the object (in case of a multi-turret object returns target of the default weapon) `structure.stat` - the STRUCTURESTAT of the structure, defined in structures.txt `structure.stattype` - structure type (likeREF_HQ etc.; refers to Script function constants)
`STRUCTUREID` | Simple. Literally just an ID of a struct.
`STRUCTURESTAT` | Simple. Type of a structure as defined in structures.txt.
`BODY` | Simple. Name of a body as defined in body.txt.
`PROPULSION` | Simple. Name of a propulsion as defined in propulsion.txt.
`ECM` | Simple. Name of an ECM as defined in ecm.txt.
`SENSOR` | Simple. Name of a sensor as defined in sensor.txt.
`CONSTRUCT` | Simple. Name of a construct as defined in construct.txt.
`WEAPON` | Simple. Name of a weapon as defined in weapons.txt.
`REPAIR` | Simple. Name of a repair type as defined in Repair.txt.
`BRAIN` | Simple. Name of a brain type as defined in Brain.txt.
`SOUND` | Simple. ID of sound used in playSound().
`LEVEL` | Simple. ID of a level as defined in GameDesc.lev.
`RESEARCHSTAT` | Simple. Name of a research topic as defined in research.txt.
`GROUP` | Complex. A group of droids. Do not confuse GROUP with in-game units' groups that can be accessed with CTRL-<number>, they have nothing in common. GROUP is an internal structure used to simplify unit management. You have access to following variables: `group.x` - average x coord `group.y` - average y coord `group.members` - number of units in the group `group.health` - average %age health of the units `group.type` - type of the group, one of: `GT_NORMAL`, `GT_COMMAND` or `GT_TRANSPORTER` (refer to Script function constants) `group.commander` - commander of the group, if type == `GT_COMMAND` or `NULLOBJECT`

NOTE: The functions objToDroid, objToStructure and objToFeature exist to convert a BASEOBJ to a droid, structure or feature if the base obj is of the right type.

NOTE: Transporters and commanders cannot be added to a GROUP.

With a complex object it is possible to access information specific to the instance of this object. Acomplex object is usually a pointer to a C structure in the code. For example a DROID is a complex object - its x, y, z can be queried whereas a DROIDID (a simple object - an integer) is just a placeholder for the numeric value of the ID.

Gets the status of some of the game TRUE/FALSE variables. Can be used to find if the reticule is up or the battle map is open, that sort of thing. Examples:

* `getGameStatus(STATUS_ReticuleIsOpen);` will return TRUE if the reticule is open (on screen) or FALSE if the reticule is not (disabled)

* `getGameStatus(STATUS_BattleMapViewEnabled);` will return TRUE if we are in the battle map mode

* `getGameStatus(STATUS_DeliveryResposInProgress);` will return TRUE if we are repositioning the delivery point

These are currently the only two options implemented ... for other game modes (like design screen or intelligence map modes) use the externed variable intMode.

`resetPlayerVisibility(int player)`

Returns the threat value of all units of a specified player within a certain area for a specified player. The user can 'calibrate' this threat value by specifying the relative weights attached to the threats of small, medium and heavy units respectively as the last three parameters to this function. The final boolean parameter allows the user to say whether they care about whether or not the units in question are presently visible. TRUE means they only add to the threat if `PlayerLooking` can see this unit (owned by `playerTarget`), FALSE means they add to the threat if even they cannot see that unit.

`bool isHumanPlayer (int pl)`

Returns true is pl is human.

`bool skVtolEnableCheck(int pl)`

True when player `pl` is actively using vtols.

`bool threatInRange(int player, int rangeX, int rangeY, int range, bool includeVTOLs)`

Returns TRUE if there is a danger for `player` at location x/y within radius `range`. If `includeVTOLs` is set to FALSE then VTOLs are ignored. All coordinates are in world units. If `range` == -1 then entire map will be searched.
