SoccerCommand Player::deMeer5 (    )

This method is the first complete simple team and defines the actions taken by all the players on the field (excluding the goalie). It is based on the high-level actions taken by the simple team FC Portugal that it released in 2000. The players do the following: if ball is kickable kick ball to goal (random corner of goal) else if i am fastest player to ball intercept the ball else move to strategic position based on your home position and pos ball Definition at line 60 of file PlayerTeams.cpp. References BasicPlayer::ACT, BasicPlayer::alignNeckWithBody(), CMD_DASH, CMD_ILLEGAL, CMD_TURNNECK, SoccerCommand::commandType, SoccerCommand::dPower, formations, FT_433_OFFENSIVE, FT_INITIAL, WorldModel::getAgentGlobalPosition(), WorldModel::getAgentObjectType(), WorldModel::getAgentStamina(), PlayerSettings::getBallConfThr(), WorldModel::getBallPos(), ServerSettings::getBallSpeedMax(), WorldModel::getConfidence(), WorldModel::getCurrentCycle(), VecPosition::getDistanceTo(), WorldModel::getFastestInSetTo(), Formations::getFormation(), ServerSettings::getGoalWidth(), WorldModel::getPlayerNumber(), PlayerSettings::getPlayerWhenToTurnAngle(), ServerSettings::getRecoverDecThr(), Stamina::getRecovery(), WorldModel::getRelativeAngle(), Stamina::getStamina(), ServerSettings::getStaminaMax(), WorldModel::getStrategicPosition(), VecPosition::getX(), BasicPlayer::intercept(), WorldModel::isBallKickable(), WorldModel::isBeforeKickOff(), WorldModel::isDeadBallThem(), WorldModel::isKickOffUs(), BasicPlayer::kickTo(), BasicPlayer::moveToPos(), OBJECT_BALL, OBJECT_SET_TEAMMATES, PITCH_LENGTH, BasicPlayer::PS, ActHandler::putCommandInQueue(), BasicPlayer::searchBall(), Formations::setFormation(), BasicPlayer::SS, BasicPlayer::teleportToPos(), BasicPlayer::turnBodyToObject(), BasicPlayer::turnBodyToPoint(), BasicPlayer::turnNeckToObject(), and BasicPlayer::WM.

SoccerCommand Player::deMeer5_goalie (    )

This method is a simple goalie based on the goalie of the simple Team of FC Portugal. It defines a rectangle in its penalty area and moves to the position on this rectangle where the ball intersects if you make a line between the ball position and the center of the goal. If the ball can be intercepted in the own penalty area the ball is intercepted and catched.

VecPosition Player::getDeadBallPosition (    )  [private]

This method returns the position to move in case of a dead ball situation. A dead ball situation occurs when the team can have a free kick, kick in, etc. The agent will move to the position behind the ball and when he is there will move to the ball again.

SoccerCommand Player::goalieMainLoop (    )  [private]

This is the main decision loop for the goalkeeper. Definition at line 221 of file Player.cpp. References deMeer5_goalie(). Referenced by mainLoop().

void Player::handleStdin (    )

This method listens for input from the keyboard and when it receives this input it converts this input to the associated action. See showStringCommands for the possible options. This method is used together with the SenseHandler class that sends an alarm to indicate that a new command can be sent. This conflicts with the method in this method that listens for the user input (fgets) on Linux systems (on Solaris this isn't a problem). The only known method is to use the flag SA_RESTART with this alarm function, but that does not seem to work under Linux. If each time the alarm is sent, this gets function unblocks, it will cause major performance problems. This function should not be called when a whole match is played! Definition at line 293 of file Player.cpp. References executeStringCommand(), and MAX_MSG. Referenced by stdin_callback().

void Player::mainLoop (    )

This is the main loop of the agent. This method calls the update methods of the world model after it is indicated that new information has arrived. After this, the correct main loop of the player type is called, which puts the best soccer command in the queue of the ActHandler.
