C standard says:

If the value of argc is greater than zero, the string pointed to by argv[0] represents the program name; argv[0][0] shall be the null character if the program name is not available from the host environment.

Write a sort of game for ludum dare and get stucked by AI but learned alot. ~.~

You should be using wmain (in console apps), wstring and wchar_t on Windows. If you need to convert a wstring to utf8 or utf8 to wstring you can use the STL converter in <codecvt>. MAX_PATH also doesn't refer to a maximum path length in a Unicode configuration, 4096 is a number I usually use if I require a path buffer.

Dunno, I just felt like I could post some code for public use. I hope google spider picks this data up so it really becomes public.

The code is used in Unity, so it might have Unity dependicies!

This is code that extracts number from string which also contains text!
I use it for numberating NPCs in the game (Unity3D), and the npcs are named like "1NPC", "NPC2", whatever, it just needs number somewhere. If no number found, it returns 0.

 public static int GetNumber(this string text) {

        var regex = @"(\d+)";

        var exp = new Regex(regex); // find a sequence of digits could be \d+
        var matches = exp.Matches(text);

        if (matches.Count == 1) // if there's one number return that 
        {
            int number = int.Parse(matches[0].Value);
            return number;
        }
        else if (matches.Count > 1) {
            Debug.LogError("ERROR");
            return 0;
        }
        else
            return 0;
    }

String interpolation! Interpolate between strings with interval [0..1].

public static string strlerp(string from, string to, float value){
        
        //extremely fast PCs breed inefficient algorithms
        List<char> newStr = new List<char>();

        int len = (from.Length > to.Length) ? from.Length : to.Length;

        for (int i = 0; i < len; i++){

            //both is default space
            char str1chr = ' ';
            char str2chr = ' ';

            //from char
            if(i < to.Length) 
                str2chr = to[i];

            //to char
            if (i < from.Length)
                str1chr = from[i];
         
            char resultchr = (char)(int)Mathf.Lerp((float)str1chr, (float)str2chr, value);
            newStr.Add(resultchr);
        }

        //clears spaces at end :)
        return new string(newStr.ToArray()).TrimEnd(new char[]{' '});
    }

Apply lambda / anonymous function recursively on game objects. This means you can
Oh, this one extends GameObject.. :)

  public delegate void gameObjectDelegate(GameObject go);

    static public void ApplyRecursively(this GameObject gObject, gameObjectDelegate GameObjectAction) {

        GameObjectAction(gObject);

        for (var i = 0; i < gObject.transform.childCount; i++) {

            var child = gObject.transform.GetChild(i);

            child.gameObject.ApplyRecursively(GameObjectAction);
        }
    }

Pick random object between the two, you input two options and it returns one of two.

    public static T PickRandom<T>(T _1, T _2) {

        var random = Random.value;

        if (random > 0.5f) 
            return _1;
        
        return _2;
    }

Hope, it is useful for anyone :)

[QUOTE=esalaka;46631462]I guess it's technically not programming, but I can't see any other suitable place to complain about TeX.

It produces lovely output but goddamn is it awful to write.

[QUOTE=ECrownofFire;46640812]Same argument applies.[/QUOTE]

No it doesn't. Consider libraries under the LGPL, if the whole thing has to be recompiled users can't patch the library themselves if there's an update.

Sooner or later. You'll see.

Gave up on the winforms gui thingie (input is a bitch), interesting concept though.

Anybody know any good modern OpenGL compatible GUI libraries that aren't GWEN?

I saw Duktape on HN and decided it'd be neat to try and do something a bit like I did for TCC ([url]https://github.com/benpye/TCCSharp/[/url]). ~180 P/Invoke signatures later and I have their example running, though it's hardly usable.

That doesn't look right though. The characters should be run together in a smooth line, not separated like that.

[sidneys1]

So I'm sure you guys remember that crazy messy code diagram I posted here a while back? Well, I just [URL="https://github.com/Sidneys1/StackingEntities/releases"]marked the first release on GitHub[/URL]. Not sure if any of you play Minecraft, but I would definitely appreciate feedback and bug reports :D

Might keep working on it, kinda fun.[/QUOTE]

Added formation control after realizing the solution isn't that complex. Find the midpoint of all units currently selected, find the offset of each unit's position from the midpoint, alter the unit's destination by that offset.
