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;}
	}
}

自动操作模式2:搜索

思路:扫描前左右三个方向,按如下规则选择方向: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
