Field Details

ACCELERATION

public static final double ACCELERATION
The acceleration of a robot, i.e. the increase of velocity when the robot moves forward, which is 1 pixel/turn.
Field Value:
1.0

DECELERATION

public static final double DECELERATION
The deceleration of a robot, i.e. the decrease of velocity when the robot moves backwards (or brakes), which is 2 pixels/turn.
Field Value:
2.0

GUN_TURN_RATE

public static final double GUN_TURN_RATE
The turning rate of the gun measured in degrees, which is 20 degrees/turn. Note, that if setAdjustGunForRobotTurn(true) has been called, the gun turn is independent of the robot turn. In this case the gun moves relatively to the screen. If setAdjustGunForRobotTurn(false) has been called or setAdjustGunForRobotTurn() has not been called at all (this is the default), then the gun turn is dependent on the robot turn, and in this case the gun moves relatively to the robot body.
Field Value:
20.0

GUN_TURN_RATE_RADIANS

public static final double GUN_TURN_RATE_RADIANS
The turning rate of the gun measured in radians instead of degrees.

MAX_BULLET_POWER

public static final double MAX_BULLET_POWER
The maximum bullet power, i.e. the maximum amount of energy that can be transferred to a bullet when it is fired, which is 3 energy points.
Field Value:
3.0

MAX_TURN_RATE

public static final double MAX_TURN_RATE
The maximum turning rate of the robot, in degrees, which is 10 degress/turn. Note, that the turn rate of the robot depends on it's velocity.
Field Value:
10.0

MAX_TURN_RATE_RADIANS

public static final double MAX_TURN_RATE_RADIANS
The maximum turning rate of the robot measured in radians instead of degrees.

MAX_VELOCITY

public static final double MAX_VELOCITY
The maximum velocity of a robot, which is 8 pixels/turn.
Field Value:
8.0

MIN_BULLET_POWER

public static final double MIN_BULLET_POWER
The minimum bullet power, i.e the amount of energy required for firing a bullet, which is 0.1 energy points.
Field Value:
0.0

RADAR_SCAN_RADIUS

public static final double RADAR_SCAN_RADIUS
The radar scan radius, which is 1200 pixels. Robots which is more than 1200 pixels away cannot be seen on the radar.
Field Value:
1200.0

RADAR_TURN_RATE

public static final double RADAR_TURN_RATE
The turning rate of the radar measured in degrees, which is 45 degrees/turn. Note, that if setAdjustRadarForRobotTurn(true) and/or setAdjustRadarForGunTurn(true) has been called, the radar turn is independent of the robot and/or gun turn. If both methods has been set to true, the radar moves relatively to the screen. If setAdjustRadarForRobotTurn(false) and/or setAdjustRadarForGunTurn(false) has been called or not called at all (this is the default), then the radar turn is dependent on the robot and/or gun turn, and in this case the radar moves relatively to the gun and/or robot body.
Field Value:
45.0

RADAR_TURN_RATE_RADIANS

public static final double RADAR_TURN_RATE_RADIANS
The turning rate of the radar measured in radians instead of degrees.

ROBOT_HIT_BONUS

public static final double ROBOT_HIT_BONUS
The amount of bonus given when a robot moving forward hits an opponent robot (ramming), which is 1.2 energy points.
Field Value:
1.0

ROBOT_HIT_DAMAGE

public static final double ROBOT_HIT_DAMAGE
The amount of damage taken when a robot hits or is hit by another robot, which is 0.6 energy points.
Field Value:
0.0
