Enforce Script Syntax – Arma Reforger

Enforce Script is the language that is used by the Enfusion engine first introduced in DayZ Standalone. It is an Object-Oriented scripting language that works with objects and classes and is similar to the C# programming language.

For DayZ, see DayZ:Enforce Script Syntax.

Data Types

ⓘ

See Scripting: Values - Types.

There are many types of data, the most common being:

Type	Description	Example	Wikipedia
Native types
bool	a bool, a.k.a true or false (and nothing else!)	bool value = true;	see Bool
int	an integer, a.k.a a whole number e.g 1, 42, -10, etc.	int value = 42;	see Integer
float	a floating point value, a.k.a a partial number e.g 1.0, 4.2, -0.1, etc	float value = 0.333;	see Float
string	a text value, a.k.a a sequence of characters, e.g "Hello there"	string owk = "Hello" + " " + "there";	see String
vector	an array of three float values e.g { 1.0, 42.2, 66.6 }	vector position = { 5, 1.5, 10 };	see Vector
Objects
class	an object able to hold properties and methods.	see Object Oriented Programming Basics	see Class
enum	a structure having static values "listed" as its properties. ⓘ An enum is not an object per se.	SCR_EBloodType myBloodType = SCR_EBloodType.O_POSITIVE;	see Enum
static array	a static array of elements (of a type) - it cannot contain a mix of types. ⚠ Arrays (dynamic or static) are the only list type that can be initialised in line.	string helloThereWords[] = { "Hello", "there" };	see Array
array<x>	a dynamic array of elements (of a type) - it cannot contain a mix of types. ⚠ Arrays (dynamic or static) are the only list type that can be initialised in line.	array<string> helloThereWords = { "Hello", "there" };	see Array
set<x>	a set of unique elements, it can only contain one type of elements. ⚠ Values are not stored in insertion order.	set<string> helloThereWords = new set<string>(); helloThereWords.Insert("Hello"); helloThereWords.Insert("there"); helloThereWords.Insert("Hello"); // ignored Print(helloThereWords.Count()); // prints '2'	see Set
map<x, y>	a map constituted of key-value pairs, where the key aspect is used to obtain the value. ⚠ Values are not stored in insertion order.	map<string, int> wordsAndLength = new map<string, int>(); wordsAndLength.Insert("General", 7); wordsAndLength.Insert("Kenobi", 6); Print(replyWordsAndLength.Get("Kenobi")); // prints '6'	see Map

Object-Oriented Programming

See Object Oriented Programming Basics and Object Oriented Programming Advanced Usage.

Operations

Assignation

Assignation operations convert the value to the expected type; see below:

// adding int and int int result = 1 + 2; // result == 3 // adding float and float float result = 1.25 + 2.75; // result == 4 // adding int and float int result = 1 + 0.9; // result == 1 - int truncates a float result int result = 0.9 + 0.9 + 0.9; // result == 2 - 2.7 truncated to 2 float result = 0.9 + 0.9 + 0.9; // result == 2.7 float result = 1 + 1.9; // result == 2.9 float result = 1.9 + 1; // result == 2.9 bool invalid = new SCR_Ray(); // error: Types 'SCR_Ray' and 'bool' are unrelated SCR_Ray instance = new SCR_Ray(); bool valid = instance; // valid == true bool result = 42; // result == true

Logic

SCR_Ray instance = new SCR_Ray(); if (instance) // identical to "instance != null" Print("Instance exists"); else Print("Instance does not exists"); string text; if (text) // identical to "!text.IsEmpty()" Print("Text is not empty"); else Print("Text is empty"); int val = 42; // same with float if (val) // identical to "val != 0" Print("Val is not zero"); else Print("Val is zero");

⚠

if (intValue) and if (stringValue) are not recommended by Scripting: Best Practices.
