All Implemented Interfaces:

IUpdateStrategy

public class WanderStrategy
extends ANoOpStrategy

An ANoOpStrategy-based strategy that randomly modifies the velocity whenever the state of the context is updated.

Field Summary

private int	_delta The maximum absolute value of any of the velocity increment's coordinates.
private IRandomizer	_rand The Randomizer used to generate the random velocity increment vector's coordinates.

public WanderStrategy()

Method Detail

updateState

public void updateState(Ball context)

Adds a random vector value to the context's velocity. The coordinates of the random vector each have an absolute value less than or equal to a stored maximum.
