Week11 聲音 /*CMP3_MCI

用openGL叫出聲音
基本:

#include <stdio.h>

#include <windows.h>

#include <mmsystem.h>

int main()

{

    PlaySoundA("Shoutgun198.wav",NULL,SND_SYNC);

    PlaySoundA("ak47.wav",NULL,SND_SYNC);

    printf("ak47\n");

    PlaySoundA("launch_dnmenu1.wav",NULL,SND_SYNC);

}

加入滑鼠點擊:

#ifdef __APPLE__

#include <GLUT/glut.h>

#else

#include <GL/glut.h>

#endif

#include <stdlib.h>

#include <stdio.h>

#include <windows.h>

#include <mmsystem.h>

void display()

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glutSwapBuffers();

}

void mouse(int button,int state,int x,int y)

{

    if(state==GLUT_DOWN){

        PlaySoundA("Shoutgun198.wav",NULL,SND_SYNC);

        PlaySoundA("ak47.wav",NULL,SND_SYNC);

        printf("ak47\n");

        PlaySoundA("launch_dnmenu1.wav",NULL,SND_SYNC);}

}

int main(int argc, char**argv)

{///只能用WAV檔，放 freeglut/bin 裡

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("Week11 sound");

    glutMouseFunc(mouse);

    glutDisplayFunc(display);

    glutMainLoop();

}

播放MP3檔:

下載CMP3_MCI.h ，放入GLUT專案內

#ifdef __APPLE__

#include <GLUT/glut.h>

#else

#include <GL/glut.h>

#endif

#include <stdlib.h>

#include <stdio.h>

#include <windows.h>

#include <mmsystem.h>

#include "CMP3_MCI.h"///雙引號，表示要在同一目錄找

CMP3_MCI myMP3;///宣告一變數 myMP3

void display()

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glutSwapBuffers();

}

void mouse(int button,int state,int x,int y)

{

    if(state==GLUT_DOWN){

        PlaySoundA("Shoutgun198.wav",NULL,SND_SYNC);

        PlaySoundA("ak47.wav",NULL,SND_SYNC);

        printf("ak47\n");

        PlaySoundA("launch_dnmenu1.wav",NULL,SND_SYNC);}

}

int main(int argc, char**argv)

{///只能用WAV檔，放 freeglut/bin 裡

    myMP3.Load("bgm1.mp3");///讀入檔案

    myMP3.Play();///播放

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("Week11 sound");

    glutMouseFunc(mouse);

    glutDisplayFunc(display);

    glutMainLoop();

}

補充:PlaySoundA("ak47.wav",NULL,SND_SYNC); 

將 SND_SYNC 改成 SND_ASYNC

           PlaySoundA("ak47.wav",NULL,SND_ASYNC); 

              聲音就會不等結束，直接再播一次(不同步)

用notepad++開啟 專案.cbp

就可以將音效檔放入專案內，而不是 freeglut/bin 內了!!

用keyboard按出聲音:

#ifdef __APPLE__

#include <GLUT/glut.h>

#else

#include <GL/glut.h>

#endif

#include <stdlib.h>

#include <stdio.h>

#include <windows.h>

#include <mmsystem.h>

#include "CMP3_MCI.h"

CMP3_MCI myMP3;

CMP3_MCI Do,Re,Mi,Fa,So;

void display()

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glutSwapBuffers();

}

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

{

    if(key=='1') Do.Play();

    if(key=='2') Re.Play();

    if(key=='3') Mi.Play();

    if(key=='4') Fa.Play();

    if(key=='5') So.Play();

}

void mouse(int button,int state,int x,int y)

{

    if(state==GLUT_DOWN){

        PlaySoundA("ak47.wav",NULL,SND_SYNC);

        printf("ak47\n");

        PlaySoundA("launch_dnmenu1.wav",NULL,SND_ASYNC);}

}

int main(int argc, char**argv)

{

    Do.Load("do.wav");

    Re.Load("re.wav");

    Mi.Load("mi.wav");

    Fa.Load("fa.wav");

    So.Load("so.wav");

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("Week11 sound");

    glutKeyboardFunc(keyboard);

    glutDisplayFunc(display);

    glutMainLoop();

}
