Colors not saving into database? - DarrenReeder - 07.10.2010

Hello...

I can trying to save my color into the database, then retrieve it again when i login...this is how i load the Color..

The problem is that the color is saving like "FF0000" in the Database, but then wen i use "SetPlayerColor(playerid, orgStats[orgID][color]" The FF0000 which should be RED in Hex...is green...

I think it might either be becuase of the strings or the field type :S anyone can help?

pawn Код:

mysql_fetch_field_row(orgStats[i][fColor], "Color");

This is how i save it:

pawn Код:

format(query, sizeof(query), "update organisation SET Color='%s' WHERE ID='%d'",orgStats[i][fColor], i);
        mysql_query(query);

This is how i set it:

pawn Код:

if(sscanf(params, "dh", org, color)) return SendClientMessage(playerid, COLOR_RED, "[USAGE] - /setcolor [orgID] [color in HEX]");
   
    orgStats[org][fColor] = color;

The Data type in my Mysql Database is a string...

Color is a number (integer), not a string.

Yes, but when you are using HEX, i KNOW its a numeric System, but wasnt sure if Hex would be allowed as an Int..

As stated above, colors are integers, that are usually represented in hex form.

Solving your problem depends on how you are setting the color variables, be it from a string retrieved from a command, or a #define, or whatever.

you can convert a hex string to integer using sscanf2
https://sampforum.blast.hk/showthread.php?tid=120356

pawn Код:

CMD:testcolor(playerid,params[])
{
     new color;
     if(!sscanf(params,"h",color))
     {
           ....
     }
}

I'm not sure if sscanf2 checks for the correct samp hex color format ( I presume it doesn't ) so if you are retrieving the colors from a command, I would check the format with something like this.

pawn Код:

if(strlen(params) == 10 && !strcmp(tmp,"0x",true,2)) //success

[edit] oops I just saw you already knew this, oh well good luck.

If i convert Hex (IE FF0000) to a Int. (16711680) would i be able to use 16711680 like:

Код:

SendClientMessage(playerid, 16711680, "I am f**king awesome ");

EDIT:
Nevermind, it doesnt

Bump

-I still cant get this to work

This will help you

pawn Код:

forward RGBAToHex(r, g, b, a); //By Betamaster
forward HexToRGBA(colour, &r, &g, &b, &a); //By Betamaster

public RGBAToHex(r, g, b, a) //By Betamaster
{
    return (r<<24 | g<<16 | b<<8 | a);
}

public HexToRGBA(colour, &r, &g, &b, &a) //By Betamaster
{
    r = (colour >> 24) & 0xFF;
    g = (colour >> 16) & 0xFF;
    b = (colour >> 8) & 0xFF;
    a = colour & 0xFF;
}

pawn Код:

stock hexstr(string[]) // By ******
{
    new
        ret,
        val,
        i;
    if (string[0] == '0' && (string[1] == 'x' || string[1] == 'X')) i = 2;
    while (string[i])
    {
        ret <<= 4;
        val = string[i++] - '0';
        if (val > 0x09) val -= 0x07;
        if (val > 0x0F) val -= 0x20;
        if (val < 0x01) continue;
        if (val < 0x10) ret += val;
    }
    return ret;
}

I do think you can actually save the color as an int and use that number the same you would with a hex value. Its worked for me on a few scripts.

    }
    return ret;
}

Yeah, didnt realise ****** had that..

How would i store it in my database? As a string, then use this before i use it??

Also, do i include "0x" or "#" at the start of the string? so like:

0xFF0000
or
#FF0000

for Red

This will work, but red in sa-mp is FF000000 (4278190080) not FF0000 (16711680)

If you use 4278190080, you will get a message with red color.

SendClientMessage(playerid, 4278190080, "I am f**king awesome ");
