org.gcs.robot.RCView

All Implemented Interfaces:

ActionListener, MouseListener, MouseMotionListener, ImageObserver, MenuContainer, Serializable, EventListener, Observer, Accessible

public class RCView
extends JPanel
implements ActionListener, MouseListener, MouseMotionListener, Observer

The RCView class is the main view of the game board. It observes the game model and determines what to draw on each square, delegating the actual drawing to RCTile. The view also implements MouseListener and MouseMotionListener, as an alternative to keyboard input. If animation is enabled, a timer moves the player as far as possible at a rate determined by DELAY.
