java 貪吃蛇代碼。移動(dòng)方面的問題。

你不是有個(gè)temp的標(biāo)識嗎？可以用這個(gè)判斷撒，記錄上一狀態(tài)。

創(chuàng)新互聯(lián)服務(wù)項(xiàng)目包括邯鄲網(wǎng)站建設(shè)、邯鄲網(wǎng)站制作、邯鄲網(wǎng)頁制作以及邯鄲網(wǎng)絡(luò)營銷策劃等。多年來，我們專注于互聯(lián)網(wǎng)行業(yè)，利用自身積累的技術(shù)優(yōu)勢、行業(yè)經(jīng)驗(yàn)、深度合作伙伴關(guān)系等，向廣大中小型企業(yè)、政府機(jī)構(gòu)等提供互聯(lián)網(wǎng)行業(yè)的解決方案，邯鄲網(wǎng)站推廣取得了明顯的社會效益與經(jīng)濟(jì)效益。目前，我們服務(wù)的客戶以成都為中心已經(jīng)輻射到邯鄲省份的部分城市，未來相信會繼續(xù)擴(kuò)大服務(wù)區(qū)域并繼續(xù)獲得客戶的支持與信任！

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;

}

}

}
