local variable "len" shadows a variable at a preceding level - Glossy42O - 03.02.2015

Hello,

I'm having a little weird problem, I don't really know what's wrong, I saw someone said change the stock name.

I did it, nothing happened.

Here is the code:

PHP код:
stock Float:GetPlayerPacketLossFromServer(playerid)
{
  new stats[401], stringstats[70];
  GetPlayerNetworkStats(playerid, stats, sizeof(stats));
  new len = strfind(stats, "PacketLoss: ");
  new Float:packetloss = 0.0;
  if(len != -1)
  {
      strmid(stringstats, stats, len, strlen(stats));
      new len = strfind(stats, "Packetloss: "); <<<<<<<Line
      if(len != -1)
      {
         strdel(stats, 0, strlen(stats));
         strmid(stringstats, stats, len, strlen(stats));
         packetloss = floatstr(stats);
      }
  }
  return packetloss;
}

It has nothing to do with the stock name.
pawn Код:
new len = strfind(stats, "PacketLoss: "); // Defined "len"
  new Float:packetloss = 0.0; 
  if(len != -1) 
  { 
      strmid(stringstats, stats, len, strlen(stats)); 
      new len = strfind(stats, "Packetloss: "); // You define it again, confusing the script
You define the same thing twice, remove one of them.
