Class CurveStrategy

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

All Implemented Interfaces:

IUpdateStrategy

public class CurveStrategy
extends ANoOpStrategy

ANoOpStrategy-based strategy that continuously modifies the velocity to produce circular motion.

Field Summary

private double	angle The incremental amount to rotate the context's velocity by each time its updateState is called (in radians).
private double	cosA Precalculated value of cos(angle)
private IRandomizer	rand Randomizer used to randomly generate the increment angle.
private double	sinA Pre-calculated value of sin(angle)
