Class ExplodeStrategy

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

All Implemented Interfaces:

IUpdateStrategy

public class ExplodeStrategy
extends ANoOpStrategy

An ANoOpStrategy-based strategy that, upon colliding with another ball, may replace its context with a number of smaller balls with the same strategy, unless the context's radius is below a minumum length, upon which the context is simply killed. The size and masses of the new balls are calculated to conservere total area and mass before and after the collision..

Field Summary

private static int	_MinRadius The minimum radius that will explode.
private static int	_NBalls The number of balls to explode into.
private static double	_Prob The probability of explosion.
private static int	_RadiusDivider The divisor of the radius when the ball explodes.

Method Summary

void	updateCollision(Ball context, Ball target) With a given probability, explodes the context ball into a number of smaller balls, unless the context's radius is below a minimum length, upon which the context is killed and no more balls are made.

Field Detail

_Prob

private static double _Prob

The probability of explosion.

_MinRadius

private static int _MinRadius

The minimum radius that will explode. smaller radius will simply kill its context ball.

_NBalls

private static int _NBalls

The number of balls to explode into.

_RadiusDivider

private static int _RadiusDivider

The divisor of the radius when the ball explodes. Equals the square root of the number of balls in order to conserve area and hence, mass.

public void updateCollision(Ball context,
                            Ball target)

With a given probability, explodes the context ball into a number of smaller balls, unless the context's radius is below a minimum length, upon which the context is killed and no more balls are made.
