public class Target
extends MobileItem

Stores state of a target as well as static data, such as target min/max speed, and min/max scaling. (note a target is something like a boat, do not confuse it with a reticle)

Constructor Summary

Target()
Initializes a target to some offscreen location, the initial state is stopped, set it to moving to have the target start moving on screen.

Constructor Detail

Target

public Target()

Initializes a target to some offscreen location, the initial state is stopped, set it to moving to have the target start moving on screen.

Method Detail

advanceInTime

public void advanceInTime(long delta)

Advances the target in time, effectively it updates the position of the boat, when the screen is redrawn it will move.

Specified by:

advanceInTime in class MobileItem

Parameters:

delta - the amount of time to elapse

sink

public void sink()

Sets the state of the target to 'sinking.'

explode

public void explode()

Sets the state of the target to 'exploding.'

isSunk

public boolean isSunk()

Returns:

True if the target is in the 'sining' state, false otherwise.

isExploding

public boolean isExploding()

Returns:

True if the target is in the 'exploding' state, false otherwise.
