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; } } }

用JAVA设计游戏：贪吃蛇游戏

用MVC方式实现的贪吃蛇游戏，共有4个类。运行GreedSnake运行即可。主要是观察者模式的使用，我已经添加了很多注释了。1、/* * 程序名称：贪食蛇 * 原作者：BigF * 修改者：algo * 说明：我以前也用C写过这个程序，现在看到BigF用Java写的这个，发现虽然作者自称是Java的初学者， * 但是明显编写程序的素养不错，程序结构写得很清晰，有些细微得地方也写得很简洁，一时兴起之 * 下，我认真解读了这个程序，发现数据和表现分开得很好，而我近日正在学习MVC设计模式， * 因此尝试把程序得结构改了一下，用MVC模式来实现，对源程序得改动不多。 * 我同时也为程序增加了一些自己理解得注释，希望对大家阅读有帮助。 */package mvcTest;/** * @author WangYu * @version 1.0 * Description: * 《/pre》 * Create on :Date :2005-6-13 Time:15:57:16 * LastModified: * History: */public class GreedSnake { public static void main(String args) { SnakeModel model = new SnakeModel(20,30);
