讓GLUT可以播聲音

#include <stdio.h>

#include <windows.h>///為了定義DWORD

#include <mmsystem.h>///為了PlaySoundA()，必須在windows.h後面

int main()

{/// WAV only 放在freeglut\bin

    PlaySoundA("Birds.wav",NULL, SND_SYNC);///For Sound

    printf("Hello World\n");

}

---------------------------------------------------------------------------------------------------------

按下滑鼠發出聲音 

#include <stdio.h>

#include <windows.h>

#include <mmsystem.h>

#include <GL/glut.h>

void display(){

    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);

    glutSwapBuffers();

}

void mouse(int button,int state,int x,int y){///當按下滑鼠，發出聲音

   if(state==GLUT_DOWN) {

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

        printf("hi\n");

   }

}

int main(int argc,char**argv){

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);

    glutCreateWindow("haha");

    glutMouseFunc(mouse);

    glutDisplayFunc(display);

    glutMainLoop();

}

--------------------------------------------------------------------------------------------------- 

讓GLUT可以播mp3並把他當BGM

先把CMP3_MCI.h程式放在專案檔裡面

#include <stdio.h>

#include <windows.h>

#include <mmsystem.h>

#include <GL/glut.h>

#include "CMP3_MCI.h"///雙引號，表示要在同一個專案檔中

CMP3_MCI myMP3;///宣告一個物件變數

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("Birds.wav",NULL, SND_SYNC);

        printf("hi\n");

   }

}

int main(int argc,char**argv){

    myMP3.Load("bgmAC.mp3");///讀入檔案，放在freeglut\bin

    myMP3.Play();///播放

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);

    glutCreateWindow("haha");

    glutMouseFunc(mouse);

    glutDisplayFunc(display);

    glutMainLoop();

}

---------------------------------------------------------------------------------------------------------------

PlaySoundA("Birds.wav",NULL, SND_ASYNC);///不用等聲音播完，就可以播下一次

-----------------------------------------------------------------------------------------------------------

讓音樂檔可以存在專案檔的位置

把箭頭所指的地方的地址改成"."

並且在codeblock讓他Reload Project

-----------------------------------------------------------------------------------------------

讓他播出鋼琴聲

#include <stdio.h>

#include <windows.h>

#include <mmsystem.h>

#include <GL/glut.h>

#include "CMP3_MCI.h"

CMP3_MCI 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("Birds.wav",NULL, SND_ASYNC);

        printf("hi\n");

   }

}

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

    ///利用鍵盤1,2,3,4,5來播出C,D,E,F,G的聲音

    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("haha");

    glutKeyboardFunc(keyboard);

    glutMouseFunc(mouse);

    glutDisplayFunc(display);

    glutMainLoop();

}

-------------------------------------------------------------------------------------------------------

讓鋼琴聲可以同時播放

#include <stdio.h>

#include <windows.h>

#include <mmsystem.h>

#include <GL/glut.h>

#include "CMP3_MCI.h"

CMP3_MCI myMP3;

CMP3_MCI C,D,E,F,G;///加入變數

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("Birds.wav",NULL, SND_ASYNC);

        printf("hi\n");

   }

}

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

    if(key=='1') C.Play();

    if(key=='2') D.Play();

    if(key=='3') E.Play();

    if(key=='4') F.Play();

    if(key=='5') G.Play();

}

int main(int argc,char**argv){

    C.Load("do.wav");

    D.Load("re.wav");

    E.Load("mi.wav");

    F.Load("fa.wav");

    G.Load("so.wav");

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);

    glutCreateWindow("haha");

    glutKeyboardFunc(keyboard);

    glutMouseFunc(mouse);

    glutDisplayFunc(display);

    glutMainLoop();
