DayZ:Enforce Script Syntax

Enforce Script is the language that is used by the Enfusion engine first introduced in DayZ Standalone. It is a Object-Oriented Scripting Language (OOP) that works with objects and classes.

Classes and Objects

Classes can be seen as a blueprint of an object. An object is an instance of a class. A class can have more than one object.

Basic Class Example

class MyClass 
{
	private string _test;

	void MyClass() 
	{
		// Constructor that will be called when class gets instantiated
	}

	void myMethod()
	{
		// Some code here
	}
	
	string getTest() 
	{
		return _test;
	}

	string setTest(value) 
	{
		_test = value;
	}
}

Instantiate and Use

Use the new operator to instantiate a class. You can access methods or attributes by using dot notation.

Example

class MyClass {
     int attributeExample = 1;

    public MyClass() {
         // Constructor
    }

    public void myMethod() {
         return "This is a string return";
    }
}

MyClass myClassI = new MyClass();
myClassI.attributeExample // 1
myClassI.myMethod // "This is a string return"

Basic Script Example

MyClass myClass = new MyClass();
myClass.myMethod();
myClass.setTest("Hello, Enforce Script!");
string str = myClass.getTest(); // str is now "Hello, Enforce Script!"

Modded class

In order to get your custom code to work and function on top of another class already in the game, a modded class is where you want to turn to.

modded class PlayerBase 
{ 
	override void EEKilled(Object killer) 
	{
		// This will call the method in which you are overriding.
		// Do this if you want to keep the original functionality
		super.EEKilled(killer);

		// Custom code here (i.e. Print(killer.GetIdentity().GetName()))
	}
}
