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.setMove(double)
,setFire(double)
,setTurnBody(double)
etc. Otherwise, these calls will never get executed. In this example the robot will move while turning:setTurnBody(90); setMove(100); execute(); while (getDistanceRemaining() > 0 && getTurnRemaining() > 0) { execute(); }
public Bullet fire(double power)
Immediately fires a bullet. The bullet will travel in the direction the gun is pointing. 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 callRules.getBulletDamage(double)
for getting the damage that a bullet with a specific bullet power will do. The specified bullet power should be betweenRules.MIN_BULLET_POWER
andRules.MAX_BULLET_POWER
. Note that the gun cannot fire if the gun is overheated, meaning thatgetGunHeat()
returns a value > 0. A event is generated when the bullet hits a robot (BulletHitEvent
), wall (BulletMissedEvent
), or another bullet (BulletHitBulletEvent
). Example:// Fire a bullet with maximum power if the gun is ready if (getGunHeat() == 0) { Bullet bullet = fire(Rules.MAX_BULLET_POWER); // 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.
public double getBattleFieldHeight()
Returns the height of the current battlefield measured in pixels.
- Returns:
- the height of the current battlefield measured in pixels.
public double getBattleFieldWidth()
Returns the width of the current battlefield measured in pixels.
- Returns:
- the width of the current battlefield measured in pixels.
public double getBodyHeading()
Returns the direction that the robot's body is facing, in radians. The value returned will be between 0 and 2 * PI (is excluded). Note that the heading in Robocode is like a compass, where 0 means North, PI / 2 means East, PI means South, and 3 * PI / 4 means West.
- Returns:
- the direction that the robot's body is facing, in radians.
- See Also:
getGunHeading()
,getRadarHeading()
public double getBodyTurnRemaining()
Returns the angle remaining in the robot's turn, in radians. This call returns both positive and negative values. Positive values means that the robot is currently turning to the right. Negative values means that the robot is currently turning to the left.
- Returns:
- the angle remaining in the robot's turn, in radians
public void getCall()
This call must be made from a robot call to inform the game that the robot made aget*
call like e.g.getX()
orgetVelocity()
. This method is used by the game to determine if the robot is inactive or not. Note: You should only make this call once in aget*
method!
- See Also:
setCall()
public double getDistanceRemaining()
Returns the distance remaining in the robot's current move measured in pixels. This call returns both positive and negative values. Positive values means that the robot is currently moving forwards. Negative values means that the robot is currently moving backwards. If the returned value is 0, the robot currently stands still.
- Returns:
- the distance remaining in the robot's current move measured in pixels.
public double getEnergy()
Returns the robot's current energy.
- Returns:
- the robot's current energy.
public Graphics2D getGraphics()
Returns a graphics context used for painting graphical items for the robot. This method is very useful for debugging your robot. Note that the robot will only be painted if the "Paint" is enabled on the robot's console window; otherwise the robot will never get painted (the reason being that all robots might have graphical items that must be painted, and then you might not be able to tell what graphical items that have been painted for your robot). Also note that the coordinate system for the graphical context where you paint items fits for the Robocode coordinate system where (0, 0) is at the bottom left corner of the battlefield, where X is towards right and Y is upwards.
- Returns:
- a graphics context used for painting graphical items for the robot.
- Since:
- 1.6.1
- See Also:
IPaintEvents.onPaint(Graphics2D)
public double getGunCoolingRate()
Returns the rate at which the gun will cool down, i.e. the amount of heat the gun heat will drop per turn. The gun cooling rate is default 0.1 / turn, but can be changed by the battle setup. So don't count on the cooling rate being 0.1!
- Returns:
- the gun cooling rate
- See Also:
getGunHeat()
,setFire(double)
public double getGunHeading()

- Returns:
- the direction that the robot's gun is facing, in radians.
- See Also:
getBodyHeading()
,getRadarHeading()
public double getGunHeat()
Returns the current heat of the gun. The gun cannot fire unless this is 0. (Calls to fire will succeed, but will not actually fire unless getGunHeat() == 0). The amount of gun heat generated when the gun is fired is 1 + (firePower / 5). Each turn the gun heat drops by the amount returned bygetGunCoolingRate()
, which is a battle setup. Note that all guns are "hot" at the start of each round, where the gun heat is 3.
- Returns:
- the current gun heat
- See Also:
getGunCoolingRate()
,setFire(double)

public void move(double distance)
Immediately moves your robot forward or backward by distance measured in pixels. This call executes immediately, and does not return until it is complete, i.e. when the remaining distance to move is 0. If the robot collides with a wall, the move is complete, meaning that the robot will not move any further. If the robot collides with another robot, the move is complete if you are heading toward the other robot. Note that both positive and negative values can be given as input, where positive values means that the robot is set to move forward, and negative values means that the robot is set to move backward. Example:// Move the robot 100 pixels forward ahead(100); // Afterwards, move the robot 50 pixels backward ahead(-50);
- Parameters:
distance
- the distance to move measured in pixels. Ifdistance
> 0 the robot is set to move forward. Ifdistance
<320 the robot is set to move backward. Ifdistance
= 0 the robot will not move anywhere, but just finish its turn.

public Bullet 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 callRules.getBulletDamage(double)
for getting the damage that a bullet with a specific bullet power will do. The specified bullet power should be betweenRules.MIN_BULLET_POWER
andRules.MAX_BULLET_POWER

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(); }
