C/C++游戏编程实例-飞翔的小鸟

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：
