Class BreathingStrategy

java.lang.Object
  ballwar.model.strategy.ANoOpStrategy
      ballwar.model.strategy.BreathingStrategy

All Implemented Interfaces:

IUpdateStrategy

public class BreathingStrategy
extends ANoOpStrategy

An ANoOpStrategy-based strategy that only only overrides the updateState behavior to make the ball's radius grower larger and smaller in a random sinusoidal manner.

Field Summary

private static double	_DeltaLowerLimit The minumum possible value for the angle increment of the sinusoid between updateState calls, in radians.
private static double	_DeltaUpperLimit The maximum possible value for the angle increment of the sinusoid between updateState calls, in radians.
private static int	_MaxRadiusLowerLimit The minimum possible value for the maximum radius of a ball.
private static int	_MaxRadiusUpperLimit The maximum possible value for the maximum radius of a ball.
private static int	_MinRadiusLowerLimit The minimum possible value for the minumum radius of a ball.
private static int	_MinRadiusUpperLimit The maximum possible value for a ball's minimum radius.
private IRandomizer	rand The Randomizer used to create the random values.
private SineMaker	sm A SineMaker object that creates a sinusoidally varying value.
