贪吃蛇之一维数组实现

贪吃蛇设计思想：

1）每一次移动

// 将最后一个快放在数组第一个，这个过程在我的word文档中有解释*****// 这个过程相当于蛇的对象数组前进了。for (int i = LEN – 2; i >= headL; i–) {ps[i].copyTo(ps[i + 1]);// 赋值拷贝，安全}ps[headL + 1].setShape(2);// 原先是头的形状改为身体形状ps[LEN – 1].setShape(3);// 原先是尾前的身体形状改为尾的形状ps[headL].set(1, headD, headX, headY);

2）吃食物

upgrade();// 判断是否升级ps[headL].setShape(2);ps[–headL] = new Partly(1, headD, headX, headY);layoutFood();
