Field Details

BOUNDING_CIRCLE_RADIUS

public static final int BOUNDING_CIRCLE_RADIUS

The radius of the bounding circle of the bot, which is a constant of 18 units.

The bounding circle of a bot is a circle going from the center of the bot with a radius so that the circle covers most of the bot. The bounding circle is used for determining when a bot is hit by a bullet.

A bot gets hit by a bullet when the bullet gets inside the bounding circle, i.e. the distance between the bullet and the center of the bounding circle is less than the radius of the bounding circle.

SCAN_RADIUS

public static final int SCAN_RADIUS

The radius of the radar's scan beam, which is a constant of 1200 units.

The radar is used for scanning the battlefield for opponent bots. The shape of the scan beam of the radar is a circle arc ("pizza slice") starting from the center of the bot. Opponent bots that get inside the scan arc will be detected by the radar.

The radius of the arc is a constant of 1200 units. This means that that the radar will not be able to detect bots that are more than 1200 units away from the bot.

The radar needs to be turned (left or right) to scan opponent bots. So make sure the radar is always turned. The more the radar is turned, the larger the area of the scan arc becomes, and the bigger the chance is that the radar detects an opponent. If the radar is not turning, the scan arc becomes a thin line, unable to scan and detect anything.

MAX_TURN_RATE

public static final int MAX_TURN_RATE

The maximum possible driving turn rate, which is max. 10 degrees per turn.

This is the max. possible turn rate of the bot. Note that the speed of the bot has a direct impact on the turn rate. The faster the speed the less turn rate.

The formula for the max. possible turn rate at a given speed is: MaxTurnRate - 0.75 x abs(speed). Hence, the turn rate is at max. 10 degrees/turn when the speed is zero, and down to only 4 degrees per turn when the bot is at max speed (which is 8 units per turn).

MAX_GUN_TURN_RATE

public static final int MAX_GUN_TURN_RATE

The maximum gun turn rate, which is a constant of 20 degrees per turn.

• Constant Field Values

MAX_RADAR_TURN_RATE

public static final int MAX_RADAR_TURN_RATE

The maximum radar turn rate, which is a constant of 45 degrees per turn.

• Constant Field Values

MAX_SPEED

public static final int MAX_SPEED

The maximum absolute speed, which is 8 units per turn.

See Also:

• Constant Field Values

MIN_FIREPOWER

public static final double MIN_FIREPOWER

The minimum firepower, which is 0.1. The gun will not fire with a power that is less than the minimum firepower, which is 0.1.

See Also:

• Constant Field Values

MAX_FIREPOWER

public static final double MAX_FIREPOWER

The maximum firepower, which is 3. The gun will fire up to this power, even if the firepower is set to a higher value.

• Constant Field Values

MIN_BULLET_SPEED

public static final double MIN_BULLET_SPEED

The minimum bullet speed is 11 units per turn.

The minimum bullet speed is the slowest possible speed that a bullet can travel and is defined by the maximum firepower: 20 - 3 x max. firepower, i.e. 20 - 3 x 3 = 11. The more power, the slower the bullet speed will be.

See Also:

• Constant Field Values

MAX_BULLET_SPEED

public static final double MAX_BULLET_SPEED

The maximum bullet speed is 19.7 units per turn.

The maximum bullet speed is the fastest possible speed that a bullet can travel and is defined by the minimum firepower. Max. bullet speed = 20 - 3 x min. firepower, i.e. 20 - 3 x 0.1 = 19.7. The lesser power, the faster the bullet speed will be.

• Constant Field Values

ACCELERATION

public static final int ACCELERATION

Acceleration is the increase in speed per turn, which adds 1 unit to the speed per turn when the bot is increasing its speed moving forward.

See Also:

• Constant Field Values

DECELERATION

public static final int DECELERATION

Deceleration is the decrease in speed per turn, which subtracts 2 units to the speed per turn when the bot is decreasing its speed moving backward. This means that a bot is faster at braking than accelerating forward.
