我九歲_Week12

2019/5/10 week10

今天內容: 鍵盤 聲音音樂WAV MP3

/1/
開啟codeblocks新增一個project
並打出程式碼

/2/
去下載WAV音檔，將音檔的位置放進程式碼中
(/部分要打兩個 因為/在程式碼中搭配某些英文字會有特殊用意)

在左邊檔名的地方按右鍵 選build option
將winmm加入。

執行就可以成功播放音檔了。

/3/
去 https://www.transmissionzero.co.uk/software/freeglut-devel/ 下載 Download freeglut 3.0.0 for MinGW
如同前幾周的方式打開codeblocks的glut這個project

在int main下面新增一行的程式碼，且加上標頭檔 #include <mmsystem.h>

再加上一些程式碼
就可以出現第一個風聲跟按鍵式的do re mi fa so了!

[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.

再來是學怎麼把mp3音檔放入
首先要先將

放進去程式的資料夾內
否則會無法執行。

再來補上程式碼加到第一行
#include "CMP3_MCI.h"
CMP3_MCI myMP3;

並將
    myMP3.Load("C:\\Users\\user\\Downloads\\music.mp3"); //填入音樂位置(同上)
    myMP3.Play();
加入int main()裡面。

仔細檢查一下就可以播放了讚讚。

好棒。
