java 贪吃蛇代码。移动方面的问题。
你不是有个temp的标识吗？可以用这个判断撒，记录上一状态。

修改如下：
public void keyPressed(KeyEvent e) {
if (start){
switch (e.getKeyCode()){
case KeyEvent.VK_UP:
if(temp==2) break;
move(0,-1);
temp =1;
break;
case KeyEvent.VK_DOWN:
if(temp==1) break;
move(0,1);
temp =2;
break;
case KeyEvent.VK_LEFT:
if(temp==4) break;
move(-1,0);
temp =3;
break;
case KeyEvent.VK_RIGHT:
if(temp==3) break;
move(1,0);
temp =4;
break;
default:
break;
}
}
}
