You don't need to use y_ini or any file systems for saving the maximum ping of the server. A simple define is enough or a variable.

pawn Код:

#define MAX_PING 54321  //Add your value.

public OnFilterScriptInit()
{
 SetTimer("DetectPing", 2000, true); //A timer would be better in handling ping detection.
 return 1;
}
forward DetectPing();

public DetectPing()
{
 for(new i; i< GetMaxPlayers(); i++)
 {
  if(!IsPlayerConnected(i)); continue;
  if(GetPlayerPing(playerid) >= MAX_PING) return Kick(playerid);
 }
 return 1;
}

Btw, you can't set anyone's ping atm.
