Jint + XNA (C #)

Question

Is it possible to use jint to control the 3D environment created using XNA (C #) and to add functionality to this environment (again using jint)?

Answer 1

As a Jint member, I would recommend Jint to you . Jint makes it simpler than what Lua does. Moreover, I do not know if this is possible with Lua, but you can give it .NET objects and play javascript with them (Jint means Javascript INTpreter). You can also protect your application with a set of permissions. Here is the same code that was introduced earlier using Jint:

    class Program
{
    static void Main(string[] args)
    {
        Program p = new Program();
        p.Run();
    }

    private void Run()
    {
        JintEngine engine = new JintEngine();
        engine.SetFunction("GTest", new Jint.Delegates.Func<object, double>(LUA_GTest));
        engine.Run("GTest([['3,3']])");
    }

    private double LUA_GTest(object d)
    {
        Console.WriteLine("Got {0} - {1}", d.GetType().ToString(), d.ToString());
        while (d is ArrayList)
        {
            d = ((ArrayList)d)[0];
            Console.WriteLine("Got {0} - {1}", d.GetType().ToString(), d.ToString());
        }
        if (d is string)
        {
            d = double.Parse((string)d);
            Console.WriteLine("Got {0} - {1}", d.GetType().ToString(), d.ToString());
        }
        if (d is double)
            return (double)d * 2;
        return 0;
    }
}

Jint - , LUA - check LuaForge

LUA - , (). ( ), .

- , . script, GTest, # LUA_GTest. , script , , , . # .

class Program
{
    static void Main(string[] args)
    {
        Program p = new Program();
        p.Run();
    }

    private void Run()
    {
        Lua lua = new Lua();
        var methodInfo = typeof(Program).GetMethod("LUA_GTest", System.Reflection.BindingFlags.Instance | System.Reflection.BindingFlags.NonPublic);
        lua.RegisterFunction("GTest", this, methodInfo);
        lua.DoString("GTest({{\"3.3\"}})");
    }

    private double LUA_GTest(object d)
    {
        Console.WriteLine("Got {0} - {1}", d.GetType().ToString(), d.ToString());
        while (d is LuaTable)
        {
            d = ((LuaTable)d)[1];
            Console.WriteLine("Got {0} - {1}", d.GetType().ToString(), d.ToString());
        }
        if (d is string)
        {
            d = double.Parse((string)d);
            Console.WriteLine("Got {0} - {1}", d.GetType().ToString(), d.ToString());
        }
        if (d is double)
            return (double)d * 2;
        return 0;
    }
}

SO, , .Net.

In general, you can create a scripting engine in your XNA application. Using the scripting engine and providing attachments to your application is not much different than calling external assemblies via public interfaces.
