    【c语言】100行代码搞定电子琴

    1.头文件

    #define _CRT_SECURE_NO_WARNINGS
#include<conio.h>//_getch()
#include<stdio.h>
#include<graphics.h>
#include <windows.h>
#include<mmsystem.h>//包含多媒体设备接口头文件
#pragma comment(lib,"winmm.lib")//加载静态库

    2.变量定义

    IMAGE bmp[7];//对应7个键的图片
IMAGE bk;//按键后变灰的图片
int music_idx = 0;
int max;//记录曲子简谱的音的个数
#define WIDTH 100//一个键的宽度
#define HEIGHT 300//界面高度
#define NUM 7//键的数目
HWND hWnd;//用于模拟按键获取消息的句柄
int music[] = { 2,1,2,1,2,3,5,3,2,1,2,1,2,3,2,1,5,0,2,1,2,1,2,3,5,3,2,3,2,1,2,2,0,2,1,2,1,2,3,5,3,2,3,2,1,6,6,0,3,2,1,2,1,0,3,2,1,2,1,0,3,2,1,2,1,0,1,2,3,1
,6,5,6,6,0,1,7,6,7,7,0,7,6,7,7,3,3,1,2,1,7,6,5,6,5,6,6,5,6,5,6,5,2,2,5,3,0,1,2,3,1,6,5,6,6,0,1,7,6,7,7,0,7,6,7,7,3,3,1,2,1,7,6,5,6,3,3,3,5,6,3,3,3,5,6,6,0,1,2,3,6,5,5,6,5,5,6,5,6,5,5,2,3,3,6,5,5,6,5,5,5,6,5,5,3,2,1,6,6,1,1,2,1,6,6,1,3,3,4,3,2,3,2,0,1,2,3,6
,5,5,6,5,5,6,5,5,2,3,6,5,5,6,5,5,6,5,5,6,5,5,3,2,1,6,6,3,2,1,6,6,6,1,1,6,3 };//定义一个简谱的数组，可以在网上搜，这个是起风了，虽然有点不太对

    3.初始化函数

    void initgame()
{hWnd=initgraph(NUM * WIDTH, HEIGHT,SHOWCONSOLE);//获取的模拟按键信息放在这个界面char buff[256];for (int i = 0; i < NUM; i++)//循环加载7个图片{memset(buff, 0, 256);sprintf(buff, "images\\%d.bmp", i + 1);loadimage(&bmp[i], buff);}//这个循环可以通用加载图片loadimage(&bk, "images\\down.bmp");//加载按下后键变灰的图片}


    4.贴图片函数

    void show()
{for (int i = 0; i < NUM; i++){putimage(i * 100, 0, &bmp[i]);//前两个坐标为图片左上角贴在界面的坐标
}}

    5.播放音乐

    void playmusic(int n)//将对应的调传过来
{char buff[50] = {0};sprintf(buff, "open ./%d.MP3 alias m",n);//这里类似于加载图片那里
mciSendString(buff, 0, 0, 0);//打开音乐
mciSendString("play m", 0, 0, 0);//播放音乐
putimage((n - 1) * 100, 0, &bk);//哪个按下就贴对应灰图片
Sleep(250);//睡眠250ms
putimage((n - 1) * 100, 0, &bmp[n-1]);//将贴的灰图片又用原来的代替
mciSendString("close m", NULL, NULL, NULL);//关闭音乐
}

    6.控制函数

    void ctrogame()
{int input;input = _getch();//input为读取按键的ASCLL值CreateThread(NULL, NULL, (LPTHREAD_START_ROUTINE)playmusic, (LPVOID)(input - 48), NULL, NULL);//创建线程，处理线程，为了处理按键不能同时按下，使用多线程}

    7.定时器函数

    void timer()
{max = sizeof(music) / sizeof(int);//个数SendMessage(hWnd,WM_KEYDOWN,(WPARAM)(music[music_idx]+48),NULL);//句柄//按键按下//对应音的音节+48对应的ascll值music_idx++;处理下一个音节if (music_idx >= max){music_idx = 0;//回到头重新播放}}

    8.主函数

    int main()
{initgame();SetTimer(hWnd, 9527, 200, (TIMERPROC)timer);//200ms进入定时函数里面//定时器id 9527（随便写）hWnd为句柄while (1){show();ctrogame();}return 0;}
