This is commonly done visually through textdraws. However, for the server-end you'll need to store information such as the player's current port, etc, and script things they can do according to the information stored. Example:

pawn Код:

enum pPortData
{
    pPort,
    bool: pInsidePort
}

new PortInformation[MAX_PLAYERS][pPortData];
stock GetPlayerPort(playerid) {
    if(PortInformation[playerid][pInsidePort] == true) {
         return PortInformation[playerid][pPort];
    }
    else return 0; // not inside of a port
}

stock ConnectToPort(playerid, port) {
  if(port >= 1 && port < 5)
  {
        PortInformation[playerid][pPort] = port;
        PortInformation[playerid][pInsidePort] = true;
        return 1;
  }
  else return 0; // bad port
}
