飞翔的小鸟游戏设计

首先需要包含以下库：

#include<stdio.h>
#include<windows.h>
#include<stdlib.h>	//包含system
#include<conio.h>

设置窗口大小：

#define WIDTH 50
#define HEIGHT 16

设置鸟的结构：

struct bird
{
	bool live;
	int x,y;
	int speed;
	int score;
	int step;
}bird;

设置洞/墙的结构：

struct hole
{
	int size;
	int yBegin;
}hole;

定义全局变量：

char map[HEIGHT - 1][WIDTH];
int scoreMax = 0;

游戏初始化设置：

void GameInit()
{
	srand(GetTickCount());
	//窗口
	char cmd[128];
	sprintf(cmd, "mode con cols=%d lines=%d", WIDTH, HEIGHT);
	system(cmd);	//将cmd窗口设定为指定大小，其中cols指定为列数，lines指定为行数。
	system("title flappy bird");	//标题
	//地图清零
	for (int i = 0; i < HEIGHT - 1; i++)
	{
		for (int j = 0; j < WIDTH; j++)
		{
			map[i][j] = ' ';
		}
	}
	//鸟初始化
	bird.live = true;
	bird.score = 0;
	bird.step = 0;
	bird.x = 7, bird.y = 7;
	bird.speed = 1;
	map[bird.y][bird.x] = '*';
	//洞
	hole.size = 7;
	//开始画面
	for (int i = 0; i < HEIGHT - 1; i++)
	{
		for (int j = 0; j < WIDTH; j++)
		{
			putchar(map[i][j]);
		}
		putchar(10);//换行
	}
	printf("\t你的分数：%d\t最高分：%d  按N键起飞", bird.score, scoreMax);
	while (!GetAsyncKeyState('N'));
}

创建墙的机制：

void CreateWall()
{	
	if (bird.step % 20 == 0)//过一段距离创建墙
	{
		hole.yBegin = rand() % 8 + 3;
		for (int i = 0; i < HEIGHT - 1; i++)
		{
			if (i < hole.yBegin || i >= hole.yBegin + hole.size)map[i][49] = '#';
			else map[i][49] = ' ';
		}
	}
}

墙向左移动的机制：

void WallMove()
{
	for (int j = 0; j < WIDTH; j++)
	{
		if (map[0][j] == '#')//有墙
		{
			if (j == 0)//墙到头
				for (int k = 0; k < HEIGHT - 1; k++)
					map[k][j] = ' ';
			else//墙没到头
			{
				for (int k = 0; k < HEIGHT - 1; k++)
				{
					if (map[k][j] == '#')
					{
						map[k][j - 1] = '#';
						map[k][j] = ' ';
					}
				}
				//鸟穿过墙
				if (j == bird.x)bird.score++;
			}
		}
	}
	//更新最高分数
	scoreMax = bird.score > scoreMax ? bird.score : scoreMax;
	//增大难度
	if (bird.step % 100 == 0)
	{
		hole.size--;
		if (hole.size == 0)hole.size = 1;
	}
	bird.step++;//墙左移，鸟级数+1
}

鸟上下移动的机制：

void BirdMove()
{
	if (GetAsyncKeyState(VK_SPACE))//上升
	{
		bird.y -= bird.speed;
		if (map[bird.y][bird.x] == '#'){bird.live = false; return;}//撞墙判断
		map[bird.y][bird.x] = '*';
		map[bird.y+ bird.speed][bird.x] = ' ';
	}
	else//下降
	{
		bird.y += bird.speed;
		if (map[bird.y][bird.x] == '#'){bird.live = false; return;}//撞墙判断
		map[bird.y][bird.x] = '*';
		map[bird.y - bird.speed][bird.x] = ' ';
	}
	//越界判断
	if(bird.y>=HEIGHT|| bird.y <= 0)bird.live = false;
}

窗口需要实时更新，实现画面的连续性：

void DrawGame()
{
	system("cls");//画面是一块一块输出的
	//输出字符
	for (int i = 0; i < HEIGHT - 1; i++)
	{
		for (int j = 0; j < WIDTH; j++)
		{
			putchar(map[i][j]);
		}
		putchar(10);//换行
	}
	printf("\t你的分数：%d\t最高分：%d  芜湖~~~", bird.score, scoreMax);
}

执行主函数：

int main()
{
	while (1)
	{
		GameInit();
		while (bird.live)
		{
			DrawGame();
			BirdMove();
			CreateWall();
			WallMove();
			Sleep(100);
		}
		system("cls");
		printf("\n\n\t你鸟没了！\n\n\t你的分数：%d\t最高分：%d\n\n", bird.score, scoreMax);
		printf("\t\t按B键重新开始");
		while (!GetAsyncKeyState('B'));
	}
	system("pause");
	return 0;
}

结果：
