GetConsoleVarAsString float Server Crash - Freaksken - 29.07.2016

So, I created this thread in the Scripting Help forums. I'll post the contents of my first post again:

Since there is no GetConsoleVarAsFloat function, I've tried the approach found in this thread: click.

Code:

stock Float:GetConsoleVarAsFloat(var[]) {
     new string[30];
     GetConsoleVarAsString(var, string, sizeof(string)); //Crash happens here
     return floatstr(string);
}

But whenever I execute GetConsoleVarAsFloat("stream_distance"); the server crashes immediately.
GetConsoleVarAsInt and GetConsoleVarAsBool don't return the correct value obviously.
I have this line in my server.cfg file:

Code:

stream_distance 300.0

Does anyone know a solution?

So, here I am reporting the problem.

EDIT:
See also this post in the Useful Functions thread.

EDIT 2:
The server also crashes if a nonexistent console variable is used.
I've updated the wiki page to show that this is a known bug.

You can use this as non stable way to check stream_distance vaule at the moment until this bug gets fixed.

how it works?
Sending rcon command varlist by the script then by a help from FileManager plugin move server log to scriptfiles folder then read last lines and get stream_distance vaule.

FileManager Plugin:
http://www.jatochnietdan.com/project/sa-mp/filemanager

Script:

PHP Code:



#include a_samp

#include filemanager


#pragma dynamic 18000


Float:GetServerVarAsFloat(var[])

{

   new Handle[5500];

   if(!strcmp(var,"stream_distance", true))

   {

      strcat(Handle, GetServerLog());

      new where = strfind(Handle, "stream_distance", true, 0);

      strdel(Handle, 0, where);

      strdel(Handle, 0, strfind(Handle,"=", true, 0)+2);

      where = strfind(Handle,"(float)", true, 0);

      if(where != -1)

      {

         strdel(Handle, where, strlen(Handle));

      }

      fremove("server_log.txt");

   }       

   else

   {

      Handle = "0.0";

   }

   return floatstr(Handle);

}


GetServerLog()

{

   SendRconCommand("varlist");

   file_copy("server_log.txt", "scriptfiles/server_log.txt");

   new File:handle = fopen("server_log.txt", io_read);

   new Handle[5500];

   if(handle)

   {

       fseek(handle, -5000, seek_end);

       new buf[350];

       while(fread(handle, buf))

       {

          strcat(Handle, buf);

       }


       new where = strfind(Handle,"Console Variables:", true, where)+1;

       while(strlen(Handle) && strfind(Handle,"Console Variables:", true, where))

       {

          where = strfind(Handle,"Console Variables:", true, where)+1;

          strdel(Handle, 0, where-1);

       }

       fclose(handle);

   }

   else

   {


      Handle = "stream_distance       = 301.000000";

   }

   return Handle;

}

Usage example:

PHP Code:



public OnFilterScriptInit()

{

   new str[128];

   format(str, sizeof str,"stream_distance Vaule is: %f", GetServerVarAsFloat("stream_distance"));

   SendClientMessageToAll(-1, str);

}

You should use other alternatives

There is no alternative, and this is a bug as described.

There is a work-around, but it's not a fix, it only just works.
