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

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.
