贪吃蛇 3.0 之 捕蛇者
大概是看错题目，只看见了加入自己的小想法，就很开心地想写一只捕蛇者。写到一半发现是要用unity，但觉得已经开始了 还是做完吧，在过程中还是遇到了很多问题，推翻了原本一半代码，写了这群有点智障的捕蛇者。
设定是：捕蛇者能抓蛇，但是需从蛇尾开始，一节节吃掉，蛇同样能吃掉捕蛇者，吃掉效果同普通食物，场景中可同时存在多个捕蛇者。
遇到的问题
- 关于捕蛇者 的设定是不只 一只，当蛇长到一定长度时就会生成捕蛇者，考虑了数组，动态数组，后觉得用HashSet 来储存捕蛇者应该会比较合适。
private HashSet<snakehunter> h = new HashSet<snakehunter>(); Add(); Remove();
2.本来用foreach遍历Set 里的捕蛇者，来确定哪个捕蛇者被吃掉，需要被移除，后来发现foreach 是只读的，不可在foreach里删除和添加。所以改成了用for循环。
for(i=0;i<h.Count;i++) { if (h.ElementAt(i).getx() == x && h.ElementAt(i).gety() == y) { h.Remove(h.ElementAt(i)); break; } }3.觉得操作不是很顺手，就把原本的跟移动方向相反移动也会死的设定 改成了 如果输入跟当前移动方向相反 则忽略此次输入。
4.最麻烦的大概是捕蛇者的移动了。 最初的设定是 四个方向随机选择一个方向移动，后来发现这样子 捕蛇者就变成了一个移动的食物，吃到蛇尾的概率太小了。 后来改成了根据蛇尾的坐标来确定移动方向，追着蛇尾跑。但是这样子又出现了一个很尴尬的事情，捕蛇者很快就追到蛇尾，但是追到蛇尾后就会一直黏在蛇尾后，因为捕蛇者和蛇速度相同，蛇长不长，捕蛇者也吃不掉蛇。有考虑过改变捕蛇者的速度，但捕蛇者如果比蛇快，那蛇一旦被追上，很快就会死掉。 最后加入一个随机函数，捕蛇者有一定几率改变方向，不会一直粘着蛇尾。
