開啟新的GLUT專案，命名week11-1 keyboard

輸入以下程式碼

用鍵盤來操作程式，if(key==27)這個鍵是Esc鍵，按下後可離開程式

Week11-2 音樂

  

開啟新的GLUT專案，命名week11-2 keyboard_PlaySound

老師傳送的音樂資料夾放在桌面上

輸入以下程式碼

#include <windows.h>

#include <GL/glut.h>

void display()

{

    glutSolidTeapot(0.3);

    glutSwapBuffers();

}

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

{

    if(key=='1') PlaySound("C:\\Users\\Administrator\\Desktop\\do-re-mi\\do.wav",NULL,SND_ASYNC);

    if(key=='2') PlaySound("C:\\Users\\Administrator\\Desktop\\do-re-mi\\re.wav",NULL,SND_ASYNC);

    if(key=='3') PlaySound("C:\\Users\\Administrator\\Desktop\\do-re-mi\\mi.wav",NULL,SND_ASYNC);

}

int main(int argc,char**argv)

{

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);

    glutCreateWindow("week11");

    glutDisplayFunc(display);

    glutKeyboardFunc(keyboard);

    glutMainLoop();

}

輸入1 2 3發出DO RE MI的聲音

Week11-3 音樂撥放

  

開啟New File並取名為week11-3 PlaySound.cpp

設定咒語 Settings→Compiler→Linker Settings  winmm

輸入程式碼

#include <windows.h>

#include <GL/glut.h>

int main(int argc,char**argv)

{

    PlaySound("C:\\Users\\Administrator\\Desktop\\do-re-mi\\do.wav",NULL,SND_ASYNC);

    PlaySound("C:\\Users\\Administrator\\Desktop\\do-re-mi\\re.wav",NULL,SND_ASYNC);

    PlaySound("C:\\Users\\Administrator\\Desktop\\do-re-mi\\mi.wav",NULL,SND_ASYNC);

    printf("Hello World\n");

}

一樣可以撥放DO RE MI

絕對路徑與相對路徑

Week11-4 自動撥放音樂

開啟新的GLUT專案，命名week11-4 CMP3_MCI_Load_Play

從第137行開始更改程式碼如以下

#include "CMP3_MCI.h" 

CMP3_MCI myMP3; 

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

{

    char filename[]="C:/Users/Administrator/Desktop/do-re-mi/suzume.mp3";

    myMP3.Load(filename);

    myMP3.Play();

要將CMP3_MCI.h也放在同個專案資料夾裡

Ctrl C+V 放入week11-4 CMP3_MCI_Load_Play資料夾

執行會有音樂

將freeglut裡bin中的freeglut.dll放入同個專案資料夾裡(week11-4)

專案上按右鍵出現選單點最下面的Properties...

接著點第二欄的Build targets

再來找到Execution working dir 工作執行目錄 將路徑改成" . "

音樂就會自動撥放了
