java小游戏程序？java做小游戏
大家好，如果您还对java小游戏程序不太了解，没有关系，今天就由本站为大家分享java小游戏程序的知识，包括java做小游戏的问题都会给大家分析到，还望可以解决大家的问题，下面我们就开始吧！

*要点分析：
*1）数据结构：matrix[][]用来存储地图上面的信息，如果什么也没有设置为false，
*如果有食物或蛇，设置为true；nodeArray，一个LinkedList，用来保存蛇的每
*一节；food用来保存食物的位置；而Node类是保存每个位置的信息。
*2）重要函数：
* changeDirection(int newDirection)，用来改变蛇前进的方向，而且只是
*保存头部的前进方向，因为其他的前进方向已经用位置来指明了。其中newDirection
*必须和原来的direction不是相反方向，所以相反方向的值用了同样的奇偶性。在测试
*的时候使用了direction%2!=newDirection%2进行判断。
* moveOn(),用来更新蛇的位置，对于当前方向，把头部位置进行相应改变。如果越界，
*结束；否则，检测是否遇到食物（加头部）或身体（结束）；如果什么都没有，加上头部，
*去掉尾部。由于用了LinkedList数据结构，省去了相当多的麻烦。
