主題 : 鍵盤

主題 : 聲音、音樂WAV、MP3

複習 : 階層T-R-T骨架

(1) 開啟一個codeblocks ( file > new > project )

(2) 選擇 console application

(3) 會得到

(4) 搜尋wav檔，選取一個喜歡得音效存起來

(5) 儲存到資料夾中並複製連結

(6) 將程式碼修改

(7) 複製貼上的連結要修改一下

( 以下為程式碼 )

///#include <iostream>

#include <windows.h> ///(0)為了mmsystem.h裡面有些宣告，需要在之前有windows.h

#include <mmsystem.h> ///(1)MultiMedia System 可播聲音

using namespace std;

int main()

{

    PlaySoundA("C:\\Users\\user\\Downloads\\thunder_clap.wav",NULL,SND_SYNC);

///播放聲音Ascii版                WAV檔                   空  聲音等待同步

    ///cout << "Hello world!" << endl;

    return 0;

}

(8) build options

(9)  Linker settings 打入winmm

(10) 即可以發出聲音

在圖片上加入聲音

(1) 先搜尋freeglut 並下載

(2) 開啟資料夾複製libfreeglut.a並改名為libglut32.a

(3) 把資料夾的連結複製

(4) 開啟一個新的 project

(5) 選擇GLUT project

(6) 貼上連結

(7) 即可以得到程式碼

(8) 打上兩行程式碼

#include <mmsystem.h> ///(1)MultiMedia System外掛，有PlaySoundA(...)可用

int main(int argc, char *argv[])

{

    PlaySoundA("C:\\Users\\user\\Downloads\\thunder_clap.wav",NULL,SND_ASYNC);///(2)

 * SND_ASYNC 聲音不等待同步

(9) 加上鋼琴的聲音，找到 glutKeyboardFunc(key); 

(10) 打上程式碼

#include <mmsystem.h>

static void key(unsigned char key, int x, int y)

{

    if(key=='1') PlaySoundA("C:\\Users\\user\\Desktop\\music\\do.wav",NULL,SND_ASYNC);

    if(key=='2') PlaySoundA("C:\\Users\\user\\Desktop\\music\\re.wav",NULL,SND_ASYNC);

    if(key=='3') PlaySoundA("C:\\Users\\user\\Desktop\\music\\mi.wav",NULL,SND_ASYNC);

    if(key=='4') PlaySoundA("C:\\Users\\user\\Desktop\\music\\fa.wav",NULL,SND_ASYNC);

    if(key=='5') PlaySoundA("C:\\Users\\user\\Desktop\\music\\so.wav",NULL,SND_ASYNC);

    ///SND_ASYNC 是sound聲音 ASYNC 不等待同步

(11) 記得要複製資料夾連結

(12) 因為剛剛只能用wva檔，如果想加mp3檔怎麼辦? 先下載 CMP3_MCI.h 檔

(13) 加入到剛剛的資料夾中

(14) 在第一行打入以下程式碼

#include "CMP3_MCI.h"

CMP3_MCI myMP3;

int     a;

float   b;

char    c;

double  d;

(15) 在將下面剛剛的程式碼改為此程式碼

///#include <mmsystem.h> ///(1)MultiMedia System外掛，有PlaySoundA(...)可用

int main(int argc, char *argv[])

{

    myMP3.Load("C:\\Users\\user\\Downloads\\music.mp3");

    myMP3.Play();

* 記得 \ 要改為 \\ 才可以跑 !!

(16) 整個程式碼為以下

#include "CMP3_MCI.h"

CMP3_MCI myMP3;

int     a;

float   b;

char    c;

double  d;

 *

 * This program is test harness for the sphere, cone

 * Spinning wireframe and smooth shaded shapes are

 * using the + and - keys.
