See Also:

_Robot.setInterruptible(boolean)

setInterruptible

public void setInterruptible(boolean interruptible)

Call this during an event handler to allow new events of the same priority, generated following this call, to restart the event handler.

Example

   onScannedRobot(ScannedRobotEvent e) {
       fire(1);
       setInterruptible(true);
       ahead(100); // If you see a robot while moving ahead,
                   // this handler will start from the top
                   // Without setInterruptible, we wouldn't
                   // receive scan events at all!
       // We'll only get here if we don't see a robot during the move.
       out.println("Ok, I can't see anyone");
   }
 

Overrides:

setInterruptible in class _Robot

Parameters:

interruptible - Whether this event handler should be interrupted on new events of same priority.

setMaxTurnRate

public void setMaxTurnRate(double newMaxTurnRate)

If you would like to turn slower than 10 degrees / tick, call this method to set it.

setMaxVelocity

public void setMaxVelocity(double newMaxVelocity)

If you would like to limit your robot's speed to less than 8, call this method.

setResume

public void setResume()

Sets the robot to resume the movement you stopped in stop() or setStop(), if any. This call returns immediately, and will not execute until you call execute() or take an action that executes.

See Also:

setStop(), Robot.stop()

setStop

public void setStop()

This call is identical to stop(), but returns immediately, and will not execute until you call execute() or take an action that executes. If there is already movement saved from a previous stop, this will have no effect. This call is equivalent to calling setStop(false);

See Also:

setStop(boolean), setResume(), Robot.stop(), Robot.resume()

setStop

public void setStop(boolean overwrite)

This call is identical to stop(boolean), but returns immediately, and will not execute until you call execute() or take an action that executes. If there is already movement saved from a previous stop, you can overwrite it by calling setStop(true).

See Also:

setStop(), setResume(), Robot.stop(), Robot.resume()

setTurnGunLeft

public void setTurnGunLeft(double degrees)

Sets the gun to turn left by degrees This call returns immediately, and will not execute until you call execute() or take an action that executes.

setTurnGunRight

public void setTurnGunRight(double degrees)

Sets the gun to turn right by degrees. This call returns immediately, and will not execute until you call execute() or take an action that executes.

setTurnRadarLeft

public void setTurnRadarLeft(double degrees)

Sets the radar to turn left by degrees. This call returns immediately, and will not execute until you call execute() or take an action that executes.

setTurnRadarRight

public void setTurnRadarRight(double degrees)

Sets the radar to turn right by degrees. This call returns immediately, and will not execute until you call execute() or take an action that executes.

waitFor

public void waitFor(Condition condition)

Does not return until condition.test() returns true. This call executes immediately. See the example robots for usage.

isAdjustRadarForRobotTurn

public boolean isAdjustRadarForRobotTurn()

Checks if the radar is set to adjust for the robot turning.

Returns:

if the radar is set to adjust for the robot turning.

See Also:

Robot.setAdjustRadarForRobotTurn(boolean)

onDeath

public void onDeath(DeathEvent event)

This method will be called if your robot dies You should override it in your robot if you want to be informed of this event. Actions will have no effect if called from this section. The intent is to allow you to perform calculations or print something out when you lose.

Overrides:

onDeath in class Robot

Parameters:

event - The event set by the game

See Also:

DeathEvent, Event

onSkippedTurn

public void onSkippedTurn(SkippedTurnEvent event)

This method will be called if you are taking an extremely long time between actions. If you receive 30 of these, your robot will be removed from 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.

Parameters:

event - The event set by the game

See Also:

SkippedTurnEvent, Event
