Script Editor – Arma Reforger
Welcome to the Enfusion Script Editor!
The Script Editor is a text editor module with integrated debugger, available from within the Enfusion Workbench that allows the user to edit, manage and debug scripts. It also provides many tools and utilities for improved efficiency like syntax highlighting, script auto-completion, fast script validation and numerous different methods of searching files, scripts and symbols within the project.
For a Script Editor newcomer's quickstart see the Getting Started section.
To learn more about the features of the Script Editor, see Script Editor Features.
Script Editor Features
The Script Editor provides many features that make writing and managing code easier.
There are numerous ways of searching through the code, namely Find File, Text Search or Find Symbol in addition to the Outline, Find In Entire Solution and Goto Declaration functionalities.
To learn more about navigating the Script Editor and the codebase, see Navigate and find code. To learn more about script syntax error checking and validation, see Compilation and Errors.
Run-time Debugging features include - but are not limited to - the Debugger, Breakpoints, Callstack and Watch. For more information regarding debugging, see Debugging.
Editor Features

Editor Personalization
The layout of the Script Editor is composed from many different windows and panels. They can be resizes, undocked from their position or docked to a preference. To learn more refer to Script Editor Windows. In addition, the Script Editor can also be customized to a certain degree by changing the font and font size it uses by default - find more information in Preferences.
Editor Shortcuts
Opposed to finding particular options from within the Editor windows manually, there is also the option to use some of (or all of) the available keyboard shortcuts - learning to use them might drastically improve the speed and efficiency of the workflow. For more information about keyboard shortcuts, see Keyboard Shortcuts.
Getting Started
In this quick introduction to the Script Editor we'll take a tour of some of the windows, tools and other features. For a more in-depth look at features of the Script Editor see Script Editor Features.
Opening Workbench
The Script Editor can be opened from the main Enfusion Workbench window at any time. There can only be one instance of the Script Editor running, but it can be opened and closed at free will.
The Script Editor can be opened from the Workbench menu bar (1) by selecting the Script Editor (2) option in the Editors drop-down menu, or by clicking the Script Editor button (3) in the Resource Manager's welcome page.
Default Layout
The default (initial) layout of the Script Editor is composed of the following windows and panels, listed in counter clockwise order as seen on the image below.
In order to learn more about individual windows, please refer to individual pages. For information about working with the windows in general, see Script Editor Windows.
- Menu Bar
- Debug
- Outline and Projects
- Watch, Errors and Find Results
- Callstack, Breakpoints and Output
- Console and Find in Files
- Find Entity, Find Symbol, Find File and Bookmarks
- Text Editor
Compilation and Errors
For error management, see Debugging.
Let's start by creating and validating our first script.
Navigate to the Projects (1) window and open (or create and open) the selected file (2).
Write the wanted code via the Text Editor (1). In our case we have a class Welcomer that provides us with a void method SayHello.
Pay close attention to the syntax error on line 11 (2). We are missing a closing bracket and a semicolon at the end of the line.
Use the Menu Bar to access the Validate Scripts (2) option in the Build tab.
Errors
The script validation has resulted in multiple errors that can be seen in the Errors (1) window of the Script Editor.
Double Click 
on any error to navigate to its location in the Text Editor.
After fixing errors and validating the scripts once again, no problems are found. The Output (1) window then shows that the compilation finished successfully.
Preferences
The Script Editor can see some settings adjusted like the font family type and the font size in the Script Editor tab of the Workbench Options.
The Workbench menu bar (1) in the main Resource Manager window allows access to the options by selecting the Workbench → Options (2) entry in the Workbench drop down menu.
The settings can then be personalized in the Options (1) window by editing the properties available in the Script Editor (2) tab.
General
Menu Bar
The menu bar allows access to some of the most sought after features of the Script Editor. The main tabs are:
- File → Provides options of working with files like Save All

Debugging
Breakpoints
To place or remove a breakpointinto/from code, Click right next to the Line Number (1) panel in the Text Editor or press F9.
The placed breakpoint will then be visible in the Breakpoints (2) window. Breakpoints can be added, removed or toggled at any time, even during run-time.
The checkboxes (/) can be used from within the Breakpoints (2) window to enable or disable given breakpoint.
Disabled breakpoints will not be hit and will simply be ignored.
Breakpoints shown as are invalid and will not be hit by the debugger.
Breakpoints are invalidated if placed in code that does not match the current code run by the connected game.
After placing a breakpoint in our code, let's run the game. With an assumption that the code will be executed, we should see theicon pop up over the first encountered breakpoint.
The icon shows the current execution step, as seen on the current line (1). The Debug (2) window can then be used to go through the code execution step by step.
Debug
The Debug window then provides us with the following options: Continue, Step Over, Step Into, Step Out and Stop.
- Continue: Continue standard code execution until next breakpoint is hit.
- Step Over: Advance the debugger without stepping into functions or methods.
- Step Into: Advance the debugger one statement at a time.
- Step Out: Advance the debugger until the current function returns.
- Stop: Stop the playmode and current debugging session.
Hovering the mouse cursor over a variable displays its current value, in the addition to Watch usage, explained below.
Connecting the debugger
Opening the Script Editor while the game is running automatically attaches the debugger via the default port, displaying the following pop up message (1).
In addition, a debugger can be connected to a different port via the Debug options from the Menu Bar.
One particularly interesting option is the Debug → Debug Custom, which allows us to connect to a user provided port.
Selecting the Debug → Debug Custom will make the following window (1) appear in which the debugger's port can be set.
To launch the Enfusion Workbench or the game itself on a specific port, use the -debuggerPort command line argument.
In the following image, the Properties (1) of a Workbench shortcut is set to port 1234 via the argument -debuggerPort 1234 as seen in the Target (2) field.
Watch
The Watch feature can be used to learn about how code changes in run-time. This allows the user to see the current values of variables while navigating through the code via the debugger.
Callstack
To learn about the code flow in run-time the Callstack feature can be used. This feature shows us the methods' call order.
It must be read from the bottom up. In this case, the depicted call originated in: MyComponent:EOnInit → MyComponent::DoWelcome → Welcomer::SayHello.
Console
In addition to the Callstack and Breakpoints, the Console is of great debugging assistance. The Console can be used in run-time to execute user scripts within the current stack.
Being in playmode is mandatory to use the console. Code which will be global to the current file can then be run. The console can also be used when a breakpoint is hit while debugging and the run code will be local to the current instance. For more information regarding breakpoints see Breakpoints.
Write code into the console and press the Run (1) button. Local variables can be used; for more information see Watch.
Results will be visible in the Output (2) window.
Virtual Machine Exceptions
From time to time, unhandled code may be encountered - like in this example below, where we are trying to call a method via a null reference. In such cases a Virtual Machine Exception will be raised.
Press Stop to halt the code execution immediately, ignore single or all cases via Ignore and Ignore All, or navigate straight to the problem using the Debug button.
