Week12_玄的筆記

Week12上課筆記

(1) 主題:鍵盤

(2) 主題:聲音，音樂

(3) 複習:階層 T-R-T骨架

(4) 作業:能操控的機器人

------------------------------------

如何播出音樂

下載Wav檔案 到資料夾

輸入下列程式碼

紅色框框處需要自行新增

----

//#include <iostream>

#include<windows.h>

#include<mmsystem.h>

//using namespace std;

int main()

{

    PlaySound("C:\\Users\\user\\Downloads\\ambul.wav",NULL,SND_SYNC);

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

   /// return 0;

}

----

創建GLUT專案

一樣要在FreeGLUT創建流程
網址複製.....創建專案...

在第137行 加入兩行程式碼

制行後
先撥放音樂  --> 再開啟視窗
----------------
製作鋼琴

加入下列五行程式碼

還有鋼琴的音階檔案( do,re,mi,fa,so) . wav檔案
就可以彈鋼琴了
------------------------

播放自己的音樂 

在專案的資料夾 加入 CMP3_MCI.h 檔案

加入程式碼

將mp3檔案放到 指定路徑上面

("C:\\Users\\user\\Downloads\\MUSIC.mp3");

按下執行 就開始播放

------------------

下列為全部程式碼

 * 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.
