    • setAhead

      public void setAhead(double distance)
      Sets the robot to move ahead (forward) by distance measured in pixels when the next execution takes place.

      This call returns immediately, and will not execute until you call execute() or take an action that executes.

      Note that both positive and negative values can be given as input, where positive values means that the robot is set to move ahead, and negative values means that the robot is set to move back. If 0 is given as input, the robot will stop its movement, but will have to decelerate till it stands still, and will thus not be able to stop its movement immediately, but eventually.

      Example:

         // Set the robot to move 50 pixels ahead
         setAhead(50);
      
         // Set the robot to move 100 pixels back
         // (overrides the previous order)
         setAhead(-100);
      
         ...
         // Executes the last setAhead()
         execute();
       
      Parameters:
      distance - the distance to move measured in pixels. If distance > 0 the robot is set to move ahead. If distance < 0 the robot is set to move back. If distance = 0 the robot is set to stop its movement.
      See Also:
    • setBack

      public void setBack(double distance)
      Sets the robot to move back by distance measured in pixels when the next execution takes place.

      This call returns immediately, and will not execute until you call execute() or take an action that executes.

      Note that both positive and negative values can be given as input, where positive values means that the robot is set to move back, and negative values means that the robot is set to move ahead. If 0 is given as input, the robot will stop its movement, but will have to decelerate till it stands still, and will thus not be able to stop its movement immediately, but eventually.

      Example:

         // Set the robot to move 50 pixels back
         setBack(50);
      
         // Set the robot to move 100 pixels ahead
         // (overrides the previous order)
         setBack(-100);
      
         ...
         // Executes the last setBack()
         execute();
       
      Parameters:
      distance - the distance to move measured in pixels. If distance > 0 the robot is set to move back. If distance < 0 the robot is set to move ahead. If distance = 0 the robot is set to stop its movement.

    • setTurnLeft

      public void setTurnLeft(double degrees)
      Sets the robot's body to turn left by degrees when the next execution takes place.

      This call returns immediately, and will not execute until you call execute() or take an action that executes.

      Note that both positive and negative values can be given as input, where negative values means that the robot's body is set to turn right instead of left.

      Example:

         // Set the robot to turn 180 degrees to the left
         setTurnLeft(180);
      
         // Set the robot to turn 90 degrees to the right instead of left
         // (overrides the previous order)
         setTurnLeft(-90);
      
         ...
         // Executes the last setTurnLeft()
         execute();
       
      Parameters:
      degrees - the amount of degrees to turn the robot's body to the left. If degrees > 0 the robot is set to turn left. If degrees < 0 the robot is set to turn right. If degrees = 0 the robot is set to stop turning.

    • setFire

      public void setFire(double power)
      Sets the gun to fire a bullet when the next execution takes place. The bullet will travel in the direction the gun is pointing.

      This call returns immediately, and will not execute until you call execute() or take an action that executes.

      The specified bullet power is an amount of energy that will be taken from the robot's energy. Hence, the more power you want to spend on the bullet, the more energy is taken from your robot.

      The bullet will do (4 * power) damage if it hits another robot. If power is greater than 1, it will do an additional 2 * (power - 1) damage. You will get (3 * power) back if you hit the other robot. You can call Rules#getBulletDamage(double)} for getting the damage that a bullet with a specific bullet power will do.

      The specified bullet power should be between Rules.MIN_BULLET_POWER and Rules.MAX_BULLET_POWER.

      Note that the gun cannot fire if the gun is overheated, meaning that Robot.getGunHeat() returns a value > 0.

      An event is generated when the bullet hits a robot, wall, or another bullet.

      Example:

         // Fire a bullet with maximum power if the gun is ready
         if (getGunHeat() == 0) {
             setFire(Rules.MAX_BULLET_POWER);
         }
         ...
         execute();
       
      Parameters:
      power - the amount of energy given to the bullet, and subtracted from the robot's energy.
      See Also:
    • setFireBullet

      public Bullet setFireBullet(double power)
      Sets the gun to fire a bullet when the next execution takes place. The bullet will travel in the direction the gun is pointing.

      This call returns immediately, and will not execute until you call execute() or take an action that executes.

      The specified bullet power is an amount of energy that will be taken from the robot's energy. Hence, the more power you want to spend on the bullet, the more energy is taken from your robot.

      The bullet will do (4 * power) damage if it hits another robot. If power is greater than 1, it will do an additional 2 * (power - 1) damage. You will get (3 * power) back if you hit the other robot. You can call Rules.getBulletDamage(double) for getting the damage that a bullet with a specific bullet power will do.

      The specified bullet power should be between Rules.MIN_BULLET_POWER and Rules.MAX_BULLET_POWER.

      Note that the gun cannot fire if the gun is overheated, meaning that Robot.getGunHeat() returns a value > 0.

      A event is generated when the bullet hits a robot (BulletHitEvent), wall (BulletMissedEvent), or another bullet (BulletHitBulletEvent).

      Example:

         Bullet bullet = null;
       

      // Fire a bullet with maximum power if the gun is ready if (getGunHeat() == 0) { bullet = setFireBullet(Rules.MAX_BULLET_POWER); } ... execute(); ... // Get the velocity of the bullet if (bullet != null) { double bulletVelocity = bullet.getVelocity(); }

      Parameters:
      power - the amount of energy given to the bullet, and subtracted from the robot's energy.
      Returns:
      a Bullet that contains information about the bullet if it was actually fired, which can be used for tracking the bullet after it has been fired. If the bullet was not fired, null is returned.

         Condition triggerHitCondition = new Condition("triggerhit") {
             public boolean test() {
                 return (getEnergy() <= trigger);
             }
         }
      
         // Add our custom event based on our condition
         addCustomEvent(triggerHitCondition);
       
      Parameters:
      condition - the condition that must be met.
      Throws:
      NullPointerException - if the condition parameter has been set to null.
      See Also:
    • removeCustomEvent

      public void removeCustomEvent(Condition condition)
      Removes a custom event that was previously added by calling addCustomEvent(Condition).

      Example:

         // Create the condition for our custom event
         Condition triggerHitCondition = new Condition("triggerhit") {
             public boolean test() {
                 return (getEnergy() <= trigger);
             }
         }
      
         // Add our custom event based on our condition
         addCustomEvent(triggerHitCondition);
         ...
         do something with your robot
         ...
         // Remove the custom event based on our condition
         removeCustomEvent(triggerHitCondition);
       
      Parameters:
      condition - the condition that was previous added and that must be removed now.

    • execute

      public void execute()
      Executes any pending actions, or continues executing actions that are in process. This call returns after the actions have been started.

      Note that advanced robots must call this function in order to execute pending set* calls like e.g. setAhead(double), setFire(double), setTurnLeft(double) etc. Otherwise, these calls will never get executed.

      In this example the robot will move while turning:

         setTurnRight(90);
         setAhead(100);
         execute();
      
         while (getDistanceRemaining() > 0 && getTurnRemaining() > 0) {

    • setEventPriority

      public void setEventPriority(String eventClass, int priority)
      Sets the priority of a class of events.

      Events are sent to the onXXX handlers in order of priority. Higher priority events can interrupt lower priority events. For events with the same priority, newer events are always sent first. Valid priorities are 0 - 99, where 100 is reserved and 80 is the default priority.

      Example:

         setEventPriority("RobotDeathEvent", 15);

      Note that you cannot change the priority for events with the special priority value -1 or 100 (reserved) as these event are system events. Also note that you cannot change the priority of CustomEvent. Instead you must change the priority of the condition(s) for your custom event(s).

      Parameters:
      eventClass - the name of the event class (string) to set the priority for
      priority - the new priority for that event class
      Since:
      1.5, the priority of DeathEvent was changed from 100 to -1 in order to let robots process pending events on its event queue before it dies. When the robot dies, it will not be able to process events.

      Specified by:
      onDeath in interface IBasicEvents

      onDeath in class Robot
      Parameters:
      event - the death event set by the game

    • onSkippedTurn

      public void onSkippedTurn(SkippedTurnEvent event)
      This method is called if the robot is using too much time between actions. When this event occur, the robot's turn is skipped, meaning that it cannot take action anymore in this turn.

      If you receive 30 skipped turn event, your robot will be removed from the round and loose the round.

      You will only receive this event after taking an action. So a robot in an infinite loop will not receive any events, and will simply be stopped.

      No correctly working, reasonable robot should ever receive this event unless it is using too many CPU cycles.

      Specified by:
      onSkippedTurn in interface IAdvancedEvents
      Parameters:
      event - the skipped turn event set by the game

      radians - the amount of radians to turn the robot's gun to the right. If radians > 0 the robot's gun will turn right. If radians < 0 the robot's gun will turn left. If radians = 0 the robot's gun will not turn, but execute.

    • turnRadarLeftRadians

      public void turnRadarLeftRadians(double radians)
      Immediately turns the robot's radar to the left by radians.

      This call executes immediately, and does not return until it is complete, i.e. when the angle remaining in the radar's turn is 0.

      Note that both positive and negative values can be given as input, where negative values means that the robot's radar is set to turn right instead of left.

      Example:

         // Turn the robot's radar 180 degrees to the left
         turnRadarLeftRadians(Math.PI);
      
         // Afterwards, turn the robot's radar 90 degrees to the right
         turnRadarLeftRadians(-Math.PI / 2);
       
      Overrides:
      turnRadarLeftRadians in class _AdvancedRadiansRobot
      Parameters:
      radians - the amount of radians to turn the robot's radar to the left. If radians > 0 the robot's radar will turn left. If radians < 0 the robot's radar will turn right. If radians = 0 the robot's radar will not turn, but execute.

      public final IAdvancedEvents getAdvancedEventListener()
      Do not call this method!

      This method is called by the game to notify this robot about advanced robot event. Hence, this method must be implemented so it returns your IAdvancedEvents listener.

      Specified by:
      getAdvancedEventListener in interface IAdvancedRobot
      Returns:
      listener to advanced events or null if this robot should not receive the notifications.
