Public Constructors

public BreakoutScreen ()

Public Methods

public void initialize ()

Initializes the shapes for the game.

public void onCollisionBetween (Ball theBall, ViewEdges edges)

Called when the ball has collided with bottom edge of the view, to subtract a life from the player. If any of the other edges are hit, then that handling occurs in the Ball class itself.

Parameters

theBall	the ball that collided
edges	the view edges that were involved in the collision

public void onCollisionBetween (Ball theBall, Brick brick)

Called when the ball has collided with a brick to update the score. The changing of the ball's velocity actually occurs in the Ball class itself.

Parameters

theBall	the ball that collided
brick	the brick that collided

public void onTouchDown (MotionEvent e)

Moves the paddle when the user touches down on the screen.

Parameters

e	the motion event

public void onTouchMove (MotionEvent e)

Moves the paddle when the user moves his or her finger on the screen.

Parameters

e	the motion event
