public class GameCanvas
This class encapsulates a very simple window in which an interactive game can be shown. This window provides the view of the game world, which is encapsulated by the game world model. This view depends upon the model. The model encapsulates the information about what is present in the game world (e.g., which sprites). At present, this class also encapsulates being an ActionListener and a KeyListener. This window is capable of listening for events that indicate it should be redrawn (in the case of multiple frames). This window is capable of listening to events that are generated by the user pressing keys on the keyboard. For these capabilities to actually be enacted, additional services must used by the event dispatcher (to connect their ability to dispatch events to this component's ability to listen)

void |
changed()
Method that is invoked when this listener wishes to respond or to react to a change that originated in whichever object this listener is listening to. |
void |
drawFrame(java.awt.Graphics2D g)
This method implements the functionality so that the scene is drawn on the back buffer, and then the entire back buffer is shown at once. |
void |
drawOnScreenElements(java.awt.Graphics2D g)
This method draws all of the required on-screen elements on the passed graphics context. |
void |
paint(java.awt.Graphics g)
This method accomplishes the painting of this canvas. |
