npctimer = SetTimerEx("NPCFollow", 100, true, "d", playerid); // where you want to start the NPC to follow.

forward NPCFollow(playerid);
public NPCFollow(playerid)
{
   new Float:x, Float:y, Float:z, pName[50];
   if(!IsPlayerNPC(playerid))
   {
     GetPlayerPos(playerid, x, y, z);
   }
   for(new i=0; i<MAX_PLAYERS; i++)
   {
     if(IsPlayerConnected(i) && IsPlayerNPC(i))
     {
        if(GetDistanceBetweenPlayers(playerid, i)<15)
        {
          SetPlayerPos(i, x-2, y, z);
        }
