（轉載）Java 貪喫蛇

剛學完多線程，嘗試着理解貪喫蛇的代碼，從別人那裏偷來的，留着備用。

package mvcTest;

 

    //July、06.11（完成測試）。
    //根據以下代碼，編譯，遊戲運行界面如下：

   




public class GreedSnake {
   public static void main(String[] args) {
       SnakeModel model = new SnakeModel(20,30);
       SnakeControl control = new SnakeControl(model);
       SnakeView view = new SnakeView(model,control);
       //添加一個觀察者，讓view成爲model的觀察者
       model.addObserver(view);
      
       (new Thread(model)).start();
   }
}

2、


package mvcTest;

//SnakeControl.java
import java.awt.event.KeyEvent;
import java.awt.event.KeyListener;


public class SnakeControl  implements KeyListener{
    SnakeModel model;

    public SnakeControl(SnakeModel model){
        this.model = model;
    }

    public void keyPressed(KeyEvent e) {
        int keyCode = e.getKeyCode();
        if (model.running){                // 運行狀態下，處理的按鍵
            switch (keyCode) {
                case KeyEvent.VK_UP:
                    model.changeDirection(SnakeModel.UP);
                    break;
                case KeyEvent.VK_DOWN:
                    model.changeDirection(SnakeModel.DOWN);
                    break;
                case KeyEvent.VK_LEFT:
                    model.changeDirection(SnakeModel.LEFT);
