Hello, same as the thread. Who has a good idea to protect textdraw, when code is:

pawn Код:

CMD:news(playerid, params[])
{
/* new text[128]; 
if(sscanf.... */

TextDrawSetString(Text:TextDrawNews, text);
return 1;
}

And my problem is: when the player send in command /news a symbol like '~', this textdraw crashing all players who see this, how i can protect this, if the script find '~' the player see the message "There are a bad symbols here!" ? Ofc, i need to protect this for the '~n~', '~r~~' etc...

use strcmp ..

Yeah, but when i use a requirement like this:

pawn Код:

if(!strcmp(text, "~", true))

My command is not work when player use a "~b~" (changing color symbols), so that is a not good think, i want some special.

look at length (optional) part

I think they mean strfind

edit: just read your post properly.

You can use a loop to count the ~ in the string, and check it is finding an even number of them.
A better way to solve the problem would be to change the color input, ie the text the player enters to something like
[b] ( blue ) [r] ( red ) etc, and use strfind to make sure there are no ~ in the text.
Then you process the string to replace these sets of symbols with the correctly formatted textdraw symbols , and then send them to the server.

That will not work!
It wouldn't allow you to execute anything that contains '~', but you need it for colors though.

I edited my post above.

Something like this ( untested ) might work.

pawn Код:

stock FormatColors( string[] )
{
    new 
        pos,
        sub[164]
    ;
    format( sub , sizeof(sub) , "%s" , string );
    pos = strfind( sub , "[g]" , true );
    while( pos != -1 )
    {
        strdel( sub , pos , pos + 3 , sizeof(sub) );
        strins( sub , "~g~" , pos );
        pos = strfind( sub , "[g]" , true );
    }
    pos = strfind( sub , "[r]" , true );
    while( pos != -1 )
    {
        strdel( sub , pos , pos + 3 , sizeof(sub) );
        strins( sub , "~r~" , pos );
        pos = strfind( sub , "[r]" , true );
    }       
    return sub;
}

Obviously you would have to add all the symbols yo wanted to allow.

SOLVED.
