自动操作模式1：扫荡
思路：不断地上下扫荡，右侧一列无蛋可跳过，有蛋或者有蛇身则上下触边时转弯。
效果：100%玩到满分，速度较慢
void Pautoplay()
{
if((snake[0].Y==1&&dir==0)||(snake[0].Y==30&&dir==2)){dir=3;return;}
if(dir==3)
{
int px=snake[0].X;
px=INC(INC(px));
for(int i=1;i<slong;i++)
if(px==snake[i].X){dir=(snake[0].Y==1?2:0);return;}
px=snake[0].X;
for(int i=1;i<=eggnum;i++)
if(px==egg[i].X){dir=(snake[0].Y==1?2:0);return;}
}
}
扫荡模式效果图：
自动操作模式2：搜索
思路：扫描前左右三个方向，按一下规则选择方向：有蛋方向优先无蛋方向，蛋距离越近的方向越优先，无蛋时距离蛇身越远的方向越优先。优化点：识别出死胡同，即使有蛋也不进入死胡同方向。
效果：速度很快，但无法取得太高的分数
