Uses of IUpdateStrategy in ballworld.model.strategy

Classes in ballworld.model.strategy that implement IUpdateStrategy

Modifier and Type	Class and Description
class	BreathingStrategy Strategy to change the context ball's radius in a random sinusoidal manner
class	Change1Strategy A composite strategy that switches the context's strategy to a Change2Strategy after a certain number of updates.
class	Change2Strategy This strategy does nothing (i.e.
class	ColorStrategy Strategy to randomly change the context ball's color.
class	CurveStrategy Strategy to make the ball curve in a circle
class	DrunkenStrategy A strategy that, at every update, randomly selects from a set of 4 strategies to be run.
class	MultiStrategy A composite strategy of two strategies.
class	StraightStrategy Simple no-op strategy, which, alone, will make the ball go in a straight line.
class	SwitcherStrategy Decorator design pattern strategy that provides an indirection layer and encapsulation over another strategy, enabling it to be switched without disturbing the context ball.
class	WanderStrategy Strategy that randomly changes the velocity of the context ball by adding random values to it.
