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;

}

}

}
