StringToHex - zgintasz - 13.06.2012

Hi guys,

I searched it, but I didn't find. I need function, that converts string to hex. I know, it's possible with sscanf, but I need to do that WITHOUT sscanf.

pawn Код:

new
    string[ 50 ],
    hex
;
format( string, sizeof( string ), "%x%x", 0x000000 , 255 );
sscanf( string, "x", hex );
printf( "%d %x", hex, hex );

I really need this...

Thanks

Not sure why you'd possibly ever need it. People have some odd views on colors, thinking they are strings and shit.

Thanks for reply, but it doesn't work correctly. I don't know why, here is my test results:

pawn Код:

new
    string[ 50 ],
    hex
;
format( string, sizeof( string ), "%x%x", 0xFF0000, 17 );
sscanf( string, "x", hex );
printf( "sscanf: %d %x", hex, hex );
hex = HexToInt( string );
printf( "HexToInt: %d %x", hex, hex );

// above
stock HexToInt(string[])
{
    if (string[0] == 0)
    {
        return 0;
    }
    new i;
    new cur = 1;
    new res = 0;
    for (i = strlen(string); i > 0; i--)
    {
        if (string[i-1] < 58)
        {
            res = res + cur * (string[i - 1] - 48);
        }
        else
        {
            res = res + cur * (string[i-1] - 65 + 10);
            cur = cur * 16;
        }
    }
    return res;
}

Код:

[13:13:41] sscanf: -16777199 -FFFFEF
[13:13:41] HexToInt: 257 101

In this case, sscanf works properly. Don't ask, why I need it

For in-game input?
