##week15-1_PlaySound

0.安裝freeglut

1.File-New-Project,GLUT專案week15-1_PlaySound

```cpp

#include <windows.h>///第1行

‵‵‵

‵‵‵cpp

int main(....)

{///mykbeat.wav放在C:\裡,NULL,SND_ASYNC撥放音樂

PlaySound("C:/Do.wav",NULL,SND_SYNC);///沒有A同步等待

    PlaySound("C:/Re.wav",NULL,SND_SYNC);

    PlaySound("C:/Mi.wav",NULL,SND_SYNC);

    PlaySound("C:/Fa.wav",NULL,SND_SYNC);

    PlaySound("C:/Sol.wav",NULL,SND_SYNC);

    PlaySound("C:/mykbeat.wav",NULL,SND_ASYNC);///有A不同步/不等待

##week15-2_PlaySound_empty

1.File-New-Project,GLUT專案

week15-2_PlaySound_empty

2.把程式碼全刪

#include <windows.h>

int main()

{

        PlaySound("C:/Do.wav",NULL,SND_SYNC);

        PlaySound("C:/mykbeat.wav",NULL,SND_ASYNC);不等待

        printf("請輸入一個整數: ");

        int n;

        scanf("%d",&n);卡住

}

現在要把工作執行目錄Project-Properties的第2分頁

Execution working dir改成小數點

##week15-3_CMP3_MCI

1.File-New-Project,GLUT專案week15-3_CMP3_MCI

2.把CMP3_MCI.h和sone.mp3和freeglut.dll都放在專案裡

3.把工作執行目錄改成小數點

‵‵‵cpp

#include "CMP3_MCI.h"

CMP3_MCI myMP3;

‵‵‵

在main()裡

‵‵‵cpp

int main(...)

{

  myMP3.Load("song.mp3");

    myMP3.Play();

##week15-4_mouse_motion_translate_rotate

{

    teapotX+=(x-oldX)/150.0;

    teapotY-=(y-oldY)/150.0;

    printf("gluTranslatef(%.3f,%.3f,0);\n",teapotX,teapotY);

    oldX =x;

    oldY =y;

    glutPostRedisplay();

}

int main(int argc,char**argv)

{

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);

    glutCreateWindow("week15-4");

    glutDisplayFunc(display);

    glutMouseFunc(mouse);

    glutMotionFunc(motion);

    glutMainLoop();
