珮珮學習日誌 Week12

電腦圖學

(1)主題:鍵盤

(2)主題:聲音、音樂WAV、MP3

程式碼如下:

#include <windows.h>///(3)因為一些基礎windows型別，要在mmsystem.h之前

#include <mmsystem.h>///(1)Multimedia System裡面有聲音的函式

//using namespace std;

int main()

{

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

}

加入printf下去的話

程式碼如下:

#include <windows.h>///(3)因為一些基礎windows型別，要在mmsystem.h之前

#include <mmsystem.h>///(1)Multimedia System裡面有聲音的函式

#include <stdio.h>

//using namespace std;

int main()

{

    printf("之前\n");///現在測一下printf()

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

    printf("中間\n");///現在測一下printf()

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

    int n;

    printf("最後要讀入一個數字，才會結束\n");///現在測一下printf()

    scanf("%d",n);

    ///播放聲音Play Sound ASCII英文的檔名...

}

TODO:在Google Chrome下載freeglut(window的mingw版) 

https://www.transmissionzero.co.uk/software/freeglut-devel/ 並把他解壓縮到桌面

之後再把解壓縮的freeglut資料夾打開來，並找到lib資料夾

再把lib裡面的libfreeglut.a複製成libglut32.a

137行加入#include <mmsystem.h>
140行加入聲音來源
順序:聲音播完再圖形出來

如下圖所示

接下來利用程式碼彈鋼琴

在94行打#include <mmsystem.h>
接下來再97行打
              if(key=='1') PlaySoundA("C:\\Users\\user\\Downloads\\do.wav",NULL,SND_ASYNC);
              if(key=='2') PlaySoundA("C:\\Users\\user\\Downloads\\re.wav",NULL,SND_ASYNC);
              if(key=='3') PlaySoundA("C:\\Users\\user\\Downloads\\mi.wav",NULL,SND_ASYNC);
              if(key=='4') PlaySoundA("C:\\Users\\user\\Downloads\\fa.wav",NULL,SND_ASYNC);
              if(key=='5') PlaySoundA("C:\\Users\\user\\Downloads\\so.wav",NULL,SND_ASYNC);

完整程式碼如下:

/*

 * GLUT Shapes Demo

 *

 * Written by Nigel Stewart November 2003

 *

 * This program is test harness for the sphere, cone

 * and torus shapes in GLUT.

 *

 * Spinning wireframe and smooth shaded shapes are

 * displayed until the ESC or q key is pressed.  The

 * number of geometry stacks and slices can be adjusted

 * using the + and - keys.
