    for (new playerid = 0; playerid < MAX_PLAYERS; playerid++)
    {
        if (!IsPlayerConnected(playerid))
            continue;

        if (PlayerNPC[playerid] == npcid)
        {
            new Float:x, Float:y, Float:z;
            NPC_GetPos(npcid, x, y, z);
            SendClientMessage(playerid, 0x00FF00FF, "Your tracked NPC %d spawned at (%.2f, %.2f, %.2f)", npcid, x, y, z);
        }
    }
    return 1;
}
