Class ThrustCommand

java.lang.Object

ihs.apcs.spacebattle.commands.ShipCommand

ihs.apcs.spacebattle.commands.ThrustCommand

public class ThrustCommand
extends ShipCommand

A command to fire a ship's thrusters, gradually increasing its speed. Each ship has four thrusters (back, front, left, right) that, when fired, propel the ship in the opposite direction (e.g. firing the back thruster moves a ship forward). Ships have a finite amount of thruster power that cannot be exceeded by the combined power of the four thrusters.

Since:

0.1

Constructor Detail

ThrustCommand

public ThrustCommand(char dir,
             double duration,
             double power)

Creates a blocking command to fire a ship's thrusters.

Parameters:

dir - which thruster to fire (one of 'B', 'F', 'L', 'R')

duration - the number of seconds to thrust

power - the percentage of thruster power to be used for this thrust

ThrustCommand

public ThrustCommand(char dir,
             double duration,
             double power,
             boolean block)

Creates a command to fire a ship's thrusters. If the ship does not have enough thruster power remaining to execute a thrust, it is ignored.

Parameters:

dir - which thruster to fire (one of 'B', 'F', 'L', 'R')

duration - the number of seconds to thrust

power - the percentage of thruster power to be used for this thrust

block - indicates if the command should block or not

Method Detail

getName

public java.lang.String getName()

Specified by:

getName in class ShipCommand

getOngoingEnergyCost

public static int getOngoingEnergyCost()

Gets the energy cost per second of this command.

Returns:

the amount of energy consumed per second while this command is executing (3)

isBlocking

public static boolean isBlocking()

Thrust commands will prevent you from executing other commands by default, pass a 'false' block argument to change this behavior.

Returns:

true, thrusting blocks by default in version 1.2.

Since:

1.1
