Arma2NET is a wrapper used for communicating between managed code and SQF code used in the game Arma 2, adding significant functionality to SQF scripting.
Arma2NET gives you the ability to use the .NET Framework from Arma 2. It is designed to be an alternative for those who don't want to use C or C++ with callExtension or Java and the JVM.
There is a wide range of language implementations that target the Common Language Runtime, so you can use C#, Python, VB.NET, F#, Ruby code and more, directly from Arma 2.
A list of languages that you can use can be found here.
- Call managed functions and manipulate the return value from SQF.
- Check the status of long-running managed functions from SQF using callbacks.
- Convert SQF literals (lists, strings, numbers etc) to .NET objects and back.
- Extend the functionality of Arma2NET by writing plugins written in any language that compiles to .NET bytecode, such as C#, F# or VB.NET.
- CommandLine (get command line used to start Arma 2)
- DateTime (get system time/UTC time)
- IronPython code executor/evaluator. Run .py script files and more from your system.
public class MyPlugin : MethodAddIn
public string Hello()
return "Hello world!";
_result = call compile ("Arma2Net.Unmanaged" callExtension "MyPlugin [Hello]");

Interesting! So could this be used to do something like have a dedicated map interface, or integrate with working gauges in the vehicles (like Flight Sim)?
Yeah, you could create an Arma2NET plugin with a GUI and a map of the terrain on a second monitor using WPF. Arma 2 would simply call the plugin's function with the map data and the data would be plotted on the second monitor.
If the MFDs have an interface an Arma2NET plugin could connect to, it could marshal data back and forth between Arma 2 and the MFDs. Arma2NET/callExtension are very powerful but are hindered by the fact you can only send/receive text data at the moment. That said, I haven't tried anything of this nature yet so the only real way to know is to try it...
