How do I do this? Check the length at compile time? - RajatPawar - 08.03.2013

Hello ! I made a text draw system for myself, with custom stocks - CreateTextBoxForPlayer and I want to add "\n" to the given string when I want to bring the textdraw to the next line. But for that, I gotta check the strlen, which I am doing using this:

pawn Код:

stock ShowTextInfoBoxToPlayer(playerid, title[], titlecolor, string[])
{
    TextDrawSetString(Textdraw1, title);
    #define strl strlen(string)//Problem's here !
    #if (20 > strl) //Problem's here !
        strins(string, "\n", 20); //Problem's here !
        #endif //Problem's here !
    TextDrawColor(Textdraw1, titlecolor);
    TextDrawSetString(Textdraw3, string);
    TextDrawShowForPlayer(playerid, Textdraw0);
    TextDrawShowForPlayer(playerid, Textdraw1);
    TextDrawShowForPlayer(playerid, Textdraw2);
    TextDrawShowForPlayer(playerid, Textdraw3);
    return 1;
}

So whenever I remove the ""//Problem's here !"" lines, it works, but ofcourse, the string goes out of the td box I have made. Any help?

I think you might be looking at this the wrong way... if I'm correct, should the line be saying this:

pawn Код:

#if (strl > 20)

Rather than 20 < strl ??
Also, remove all //Problem's here ! from the code if you think it might be disrupting it's effect.

Not to mention, you should change the line from \n to ~n~.

pawn Код:

strins(string, "~n~", 20);

Benzo tell me what's the difference between strl > 20 and 20 < strl... also if can't get to a solution try putting ~n~ in game in order to make a new line or sth

It was a typo... it was meant to say 20 > strl.

Oh, yes, Benzo, I tried it all, and yes, my mistake, the ~n~ should be there. I just want to make it so that it returns an error when the string is longer than 33 without a ~n~ so that the given string doesn't go out of the textdraw box.
Here's my loop:

pawn Код:

for(new s; s<strlen(string); s++)
    {
        if ( string[s] != '~')
        {
            if(string[s+1] == 'n')
            {
                if(string[s+2] == '~')
                {
                  break;
                }
            }
        }
        count++;
    }
    #if(count > 33) #error You must use ~n~ at the 33rd character for the .. to not go outta the box
       #endif

Yeah, I figured that out due to the warning I was getting! But is there any other way of doing this? One way is to have a stock for creating and another for showing, so that you can check the string. But that's where my problem is, I do not know how to go on with assigning IDs to created ''Textdraw menus'' (the FS I am creating.)

Because that will compile perfectly and send the error ingame/on it's use. I want it not to compile at all, I wanted to have a precompiler check, but I guess that's not possible !
