All Implemented Interfaces:

Command

public class PingCommand
extends AbstractCommand

Display the ping to the server. To compute the ping of tetrinet and tetrifast clients we send the playernum message that triggers a team message as response. We assume the ping is half the time between the request and the response. Since a command cannot wait for a client response this command must work with the PingFilter that is processing all team messages. This command sets the client properties command.ping=true and command.ping.time and send the playernum message. The filter will then listen for team messages and check if the property command.ping is true. If so it will display the ping of the player.
