🔴播放wav檔
#include <windows.h>
#include <mmsystem.h>
int main()
{///播聲音 正常的ASCII檔名,空,聲音要同步
    PlaySoundA("chaha.wav",NULL,SND_SYNC);
}///檔案要在(freeglut\bin資料夾裡)


🔴試著播出多個wav檔，按鍵盤發出聲音
#include <windows.h>
#include <mmsystem.h>
#include <GL/glut.h>
void display()
{
}
void keyboard(unsigned char key,int x,int y)
{                                                              ///不要同步，不等結束
    if(key=='1')PlaySoundA("do.wav",NULL,SND_ASYNC);
    if(key=='2')PlaySoundA("re.wav",NULL,SND_ASYNC);
    if(key=='3')PlaySoundA("mi.wav",NULL,SND_ASYNC);
    if(key=='4') PlaySoundA("fa.wav",NULL,SND_ASYNC);
    if(key=='5')PlaySoundA("so.wav",NULL,SND_ASYNC);
}
int main(int argc,char**argv)
{
    glutInit(&argc,argv);
    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);
    glutCreateWindow("week12 sound");

    glutDisplayFunc(display);
    glutKeyboardFunc(keyboard); ///鍵盤有函式

    glutMainLoop();
}


🔴播出mp3檔，播放時還是可以按鍵盤發出聲音
-->但這個按鍵不能發出和弦
#include <windows.h>
#include <mmsystem.h>
#include <GL/glut.h>
#include "CMP3_MCI.h"
CMP3_MCI mp3;
void display()
{

}
void keyboard(unsigned char key,int x,int y)
{
    if(key=='1')PlaySoundA("do.wav",NULL,SND_ASYNC);
    if(key=='2')PlaySoundA("re.wav",NULL,SND_ASYNC);
    if(key=='3')PlaySoundA("mi.wav",NULL,SND_ASYNC);
    if(key=='4') PlaySoundA("fa.wav",NULL,SND_ASYNC);
    if(key=='5')PlaySoundA("so.wav",NULL,SND_ASYNC);
}
int main(int argc,char**argv)
{
    mp3.Load("music.mp3");
    mp3.Play();
    glutInit(&argc,argv);
    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);
    glutCreateWindow("week12 sound");

    glutDisplayFunc(display);
    glutKeyboardFunc(keyboard);

    glutMainLoop();

🔴更改工作目錄  將原本執行的目錄改成小數點"."


🔴將原本目錄中要執行的聲音檔及freeglut.dll檔移動到專案的目錄裡


🔴這樣即使換一台電腦使用，也不會因目錄名稱不同而不能執行


🔴做出類似射擊遊戲的感覺，球撞到牆壁有音效，滑鼠點擊有槍聲
