Question

如何在C++编的小游戏中添加背景音乐？？？

Answer 1

1：功能差劲的Playsound函数
事例代码如下
#include<windows.h>
#include<stdio.h>
#pragma comment(lib,"WinMM.Lib")
void main()
{
PlaySound("c:\\dui12.wav",NULL,SND_FILENAME|SND_ASYNC);
}
2:功能和Playsound函数一样差劲的函数undplaysound
#include<windows.h>
#include<stdio.h>
#pragma comment(lib,"WinMM.Lib")
void main()
{
undPlaySound("c:\\dui12.wav",NULL,SND_FILENAME|SND_ASYNC);
}
3：功能强大的函数，支持混音的MCI类
事例代码如下
#include<windows.h>
#include "mmsystem.h"//导入声音头文件
#pragma comment(lib,"winmm.lib")//导入声音头文件库
#include<stdio.h>
void PlayMp3() ;
void main()
{
PlayMp3() ;
PlaySound("C:\\Normal2.wav", NULL, SND_FILENAME | SND_ASYNC | SND_LOOP);

system("pause");

}
void PlayMp3()
{
char buf[128];
char str[128] = {0 };
int i = 0;

//use mciSendCommand
MCI_OPEN_PARMS mciOpen;
MCIERROR mciError;
//SetWindowText(NULL,"12345");
mciOpen.lpstrDeviceType = "mpegvideo";
mciOpen.lpstrElementName = "c:\\WELCOME.WAV";
mciError = mciSendCommand(0,MCI_OPEN,MCI_OPEN_TYPE | MCI_OPEN_ELEMENT,(DWORD)&mciOpen);
if(mciError)
{
mciGetErrorString(mciError,buf,128);
printf("send MCI_OPEN command failed:%s\n",buf);
return;
}
UINT DeviceID = mciOpen.wDeviceID ;
MCI_PLAY_PARMS mciPlay;

mciError = mciSendCommand(DeviceID,MCI_PLAY,0 ,(DWORD)&mciPlay);
if(mciError)
{
printf("send MCI_PLAY command failed\n");
return;
}
}
4：功能垃圾的方法，是启动电脑的一个播放软件播放音乐
#include <iostream>
#include<fstream>
using namespace std;
int main()
{
system("D:\\我的音乐\\01.mp3");
cin.get();
return 0;
}
5：功能更加强大DX
这个不做介绍，太多了，我就不敲代码，累的慌！网上有讲解的

Answer 3

最简单的，playsound
稍微复杂点、可以加入一些控制元素：MCI
再复杂点：waveoutXXX，midioutXXX
上面可参考：msdn(win2 and com\Graphics and multimedia\windows multimedia\...)
如果用DX，则有DirectSound，DirectMusic等等，
这些就要看Direct SDK了(direct7,8,9等版本)
上述方法都能找到现成的代码。哈

有个函数叫 PlaySound 去查查这个用法把
