更多敬请期待



前言

贪吃蛇游戏:用键盘上下左右控制蛇的方向,寻找吃的东西,每吃一口就能得到一定的积分,而且蛇的身子会越吃越长,身子越长玩的难度就越大,不能碰墙,不能咬到自己的身体,更不能咬自己的尾巴,等到了一定的分数,就能过关,然后继续玩下一关。

这个游戏大家从小玩到大,非常受广大玩家的喜爱,那么自己怎么才能进行制作呢?


提示:以下是本篇文章正文内容,为大家带来【贪吃蛇阉割版】,下面C语言案例可供参考

一、贪吃蛇是什么?

1. 名词释义

贪吃蛇游戏是一款休闲益智类游戏,有PC和手机等多平台版本。既简单又耐玩。该游戏通过控制蛇头方向吃蛋,从而使得蛇变得越来越长。

贪吃蛇游戏最初为单机模式,后续又陆续推出团战模式、赏金模式、挑战模式等多种玩法。

2. 贪吃蛇阉割版

由于市面上的贪吃蛇更新迭代太快,很多新功能、新玩法博主无法实现,只因尚未学习到那里。

所以这里的贪吃蛇游戏功能较少,于是称为阉割版。

3. 游戏规则

  1. 不能穿墙,不能咬到自己
  2. 用↑.↓.←.→分别控制蛇的移动
  3. F1 为加速,F2 为减速
  4. 按空格键暂停游戏,再按空格键继续
  5. ESC :退出游戏.space:暂停游戏

二、源程序

提示:函数拆讲中的代码会附有注释,但是完整程序中不会有注释

1. 预定义

#define U	1
#define D	2
#define L	3
#define R	4 

蛇的状态,U:上 ;D:下;L:左 R:右

2. 全局变量

typedef struct snake                    /* 蛇身的一个节点 */
{
   
	int		x;
	int		y;
	struct snake	*next;
}snake;
int	score = 0, add = 10;            /* 总得分与每次吃食物得分 */
int	status, sleeptime = 200;        /* 蛇前进状态,每次运行的时间间隔 */
snake	*head, *food;                   /* 蛇头指针,食物指针 */
snake	*q;                             /* 遍历蛇的时候用到的指针 */
int	endgamestatus = 0;              /* 游戏结束的情况,1:撞到墙;2:咬到自己;3:主动退出游戏。 */
HANDLE	hOut;                           /* 控制台句柄 */

3. 函数拆讲(含注释)

		keyboardControl();      /*按键控制 */
		break;
	case 2:
		explation();            /* 游戏说明函数 */
		break;
	case 3:
		exit( 0 );              /* 退出游戏 */
		break;
	default:
		color( 12 );
		gotoxy( 40, 28 );
		printf( "请输入1—3之间的数!" );
		_getch();               /* 输入任意键 */
