Mypanel的 run方法里要调用repaint方法 否则你的repaint方法只会在keyPressed发生的时候才调用
修改一下两个地方
（1）
// 键盘获取事件的函数
public void keyPressed(KeyEvent arg0) {
// TODO Auto-generated method stub
if (arg0.getKeyCode() == KeyEvent.VK_J) {
if (hero.shot.size() 5) {
hero.shott();
}
}
if (arg0.getKeyCode() == KeyEvent.VK_W) {
hero.setSDC(hero.getSpeed(), 0, hero.getColor());
hero.moveUp();
} else if (arg0.getKeyCode() == KeyEvent.VK_S) {
hero.setSDC(hero.getSpeed(), 1, hero.getColor());
hero.moveDown();
} else if (arg0.getKeyCode() == KeyEvent.VK_A) {
hero.setSDC(hero.getSpeed(), 2, hero.getColor());
hero.moveLeft();
} else if (arg0.getKeyCode() == KeyEvent.VK_D) {
hero.setSDC(hero.getSpeed(), 3, hero.getColor());
hero.moveRight();
}
/**
* 这个repaint注释掉
*/
//this.repaint();
}
（2）
// 线程
/**
* 一秒钟60帧
*/
public void run() {
// TODO Auto-generated method stub
while(true){
this.repaint();
try {
Thread.sleep(1000 / 60);
} catch (InterruptedException e) {
// TODO 自动生成的 catch 块
e.printStackTrace();
}
}
}
