public class Playfield
extends Canvas
implements Runnable, CollisionArena
A surface upon which Sprites are animated. Playfields are responsible for animating the sprites.

Each Playfield comes complete with two collision detectors: an edge collision detector and a sprite collision detector. Playfield is an abstract class: extensions must implement the following methods:

void paintBackground(Graphics)
void void spriteCollision(Sprite sprite, Sprite other)
void void edgeCollision (Sprite sprite, Sprite other)

CollisionArena, Sprite, SpriteCollisionDetector, EdgeCollisionDetector, SimpleAnimationTest, BumpAnimationTest, TwoDrinkersAnimationTest
