public class LevelCanvas

extends javax.microedition.lcdui.game.GameCanvas

implements java.lang.Runnable

LevelCanvas manages the multiple layers of Sprites and TiledLayers, by controlling the LayerManager, while running the animation beat methods for them. it accepts the keyStates from the handset and also handels many aspects of game play/events

boolean	overlapsPlayer(javax.microedition.lcdui.game.Sprite sprite) returns true if the sprite passed collides with with the player sprite
void	playBang() Calls the midlet to play an explosion
void	quit() quits the game and returns the user to the menu using the midlet
int	random(int size) calls the midlet to return a random int limited by the int passed
void	removeLayer(javax.microedition.lcdui.game.Sprite s) removes a layer from the manager of the sprite passed
void	run() creats a current thread and handels produces a beat to handle the constant drawing and flushing
void	start() builds upon the animationThread, starts it and records the start time
void	stop() records the gameduration and stops the animationThread
void	vibrate(int millis) calls the midlet to vibrate for a passed int in milleseconds
