java游戏开发--简单的几行代码就完成了驱动小精灵的编程


		  今天编写了一个驱动小精灵，简短的几行代码就完成了；虽然简单但是用处很大，很多用java、android开发的游戏界面布局都或多或少的用的这些简单代码。
packagecom.csdn.code;
 
importjava.awt.Color;
importjava.awt.Frame;
importjava.awt.Graphics;
importjava.awt.event.WindowAdapter;
importjava.awt.event.WindowEvent;
public classDriveElf extends Frame{
      private int x = 40;   //精灵在画板上的初始位置—横坐标
      private int y = 40;   //精灵在画板上的初始位置—纵坐标
      private int arc = 320;   //精灵嘴张合的角度
      public DriveElf() {
           setBounds(200,200,600,500);
           setVisible(true);
           setBackground(Color.cyan);
           addWindowListener(new WindowAdapter(){
                 public voidwindowClosing(WindowEvent e) {
                      System.exit(0);
                 }             
           });
           new Thread(){
                 public void run(){
                     while(true){
                            // 两个for循环作用分别是使精灵在画板上移动
                            for(inti=0;i<40;i++){
                                  arc += 1;
                                  x += 10;
                                  y += 3;
                                  }
                                  try{
                                       Thread.sleep(50);
                                       }catch(Exceptione){
                                             e.printStackTrace();
                                       }
                                       repaint();
                            for(inti=0;i<40;i++){
                                  arc -= 1;
                                  x -= 8;
                                  y -= 1;
                                  try{
                                       Thread.sleep(100);
                                        }catch(Exceptione){
                                             e.printStackTrace();
                                       }
                                       repaint();
                            }                        
                     }
                 }
           }.start();
      }
//喷绘方法，实现在画板上的绘图
      public void paint(Graphics g){
