贪吃蛇 -【C语言小游戏】

非基于打印数组的C语言版贪吃蛇

 

部分代码

坐标结构体

struct coordinate
{
	int x;
	int y;
};

贪吃蛇结构体

struct snake
{
	coordinate poshe;
	coordinate posta;
	coordinate posbody[maxlen];
	int direction;
	int length;
} eatsnake;

移动一步

void moveOneSept()
{
	oper_count++;
	if(Is_eatfood()==0)
	{
		display(eatsnake.posbody[eatsnake.length-1],snackpump);
	}
	for(int i=eatsnake.length-1; i>0; i--)
	{
		eatsnake.posbody[i].x=eatsnake.posbody[i-1].x;
		eatsnake.posbody[i].y=eatsnake.posbody[i-1].y;
	}
	if(eatsnake.direction==Up)
	{
		eatsnake.posbody[0].y--;
	}
	else if(eatsnake.direction==Down)
	{
		eatsnake.posbody[0].y++;
	}
	else if(eatsnake.direction==Left)
	{
		eatsnake.posbody[0].x-=2;
	}
	else if(eatsnake.direction==Right)
	{
		eatsnake.posbody[0].x+=2;
	}
	display(eatsnake.posbody[0],snackbody);
}

吃到食物

int Is_eatfood()

	{
		return 1;
	}

}

		crenewfood();
	}
}

判断游戏结束

int GameOver()
{
	int flag=0;
	for(int i=1; i<eatsnake.length; i++)
	{
		if(eatsnake.posbody[i].x==eatsnake.posbody[0].x
  		 &&eatsnake.posbody[i].y==eatsnake.posbody[0].y)
		{
			flag=1;
			SetPos(5,5);
			return 1;
		}
	}
	if(		  eatsnake.posbody[0].x<0
	          ||eatsnake.posbody[0].y<0
	          ||eatsnake.posbody[0].x>len

	  )
	{
		SetPos(5,5);
		return 2;
	}
	return 0;
}
