播放音效

 

今天上課教如何撥放音效

下載下來的音樂要放到執行目錄

(freeglut\bin裡面)

程式碼:

#include <windows.h>

#include <GL/glut.h>

void display()

{

    glClear(GL_COLOR_BUFFER_BIT| GL_DEPTH_BUFFER_BIT);

    glutSolidTeapot(0.3);

    glutSwapBuffers();

}

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

{

    if(key=='1') PlaySound("do.wav", NULL, SND_ASYNC);

    if(key=='2') PlaySound("re.wav", NULL, SND_ASYNC);

    if(key=='3') PlaySound("mi.wav", NULL, SND_ASYNC);

}

int main(int argc, char**argv)

{

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("week10");

    glutDisplayFunc(display);

    glutKeyboardFunc(keyboard);

    glutMainLoop();

}

播放mp3檔要先下載MP3_MCI檔案

並放在專案目錄裡面，下載mp3檔

程式碼:

#include <windows.h>

#include <GL/glut.h>

#include "CMP3_MCI.h"

CMP3_MCI mp3;

void display()

{

    glClear(GL_COLOR_BUFFER_BIT| GL_DEPTH_BUFFER_BIT);

    glutSolidTeapot(0.3);

    glutSwapBuffers();

}

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

{

    if(key=='1') PlaySound("do.wav", NULL, SND_ASYNC);

    if(key=='2') PlaySound("re.wav", NULL, SND_ASYNC);

    if(key=='3') PlaySound("mi.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("week10");

    glutDisplayFunc(display);

    glutKeyboardFunc(keyboard);

    glutMainLoop();

}

再增加一個按滑鼠也有音效的程式碼:

#include <windows.h>

#include <GL/glut.h>

#include "CMP3_MCI.h"

CMP3_MCI mp3;

void display()

{

    glClear(GL_COLOR_BUFFER_BIT| GL_DEPTH_BUFFER_BIT);

    glutSolidTeapot(0.3);

    glutSwapBuffers();

}

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

{

    if(key=='1') PlaySound("do.wav", NULL, SND_ASYNC);

    if(key=='2') PlaySound("re.wav", NULL, SND_ASYNC);

    if(key=='3') PlaySound("mi.wav", NULL, SND_ASYNC);

}

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

{

    if(state==GLUT_DOWN) PlaySound("shot.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("week10");

    glutDisplayFunc(display);

    glutKeyboardFunc(keyboard);

    glutMouseFunc(mouse);

    glutMainLoop();

}

這個程式碼可以讓滑鼠左中右鍵分別有不同音效

#include <windows.h>

#include <GL/glut.h>

#include "CMP3_MCI.h"

CMP3_MCI mp3;

CMP3_MCI shot1,shot2,shot3;

void display()

{

    glClear(GL_COLOR_BUFFER_BIT| GL_DEPTH_BUFFER_BIT);

    glutSolidTeapot(0.3);

    glutSwapBuffers();

}

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

{

    if(key=='1') PlaySound("do.wav", NULL, SND_ASYNC);

    if(key=='2') PlaySound("re.wav", NULL, SND_ASYNC);

    if(key=='3') PlaySound("mi.wav", NULL, SND_ASYNC);

}

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

{

    if(state==GLUT_DOWN&&button==GLUT_LEFT_BUTTON) shot1.Play();

    if(state==GLUT_DOWN&&button==GLUT_MIDDLE_BUTTON) shot2.Play();

    if(state==GLUT_DOWN&&button==GLUT_RIGHT_BUTTON) shot3.Play();

}

int main(int argc, char**argv)

{

    shot1.Load("1.wav"); shot2.Load("2.mav"); shot3.Load("3.wav");

    mp3.Load("music.mp3");

    mp3.Play();

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("week10");

    glutDisplayFunc(display);

    glutKeyboardFunc(keyboard);

    glutMouseFunc(mouse);

    glutMainLoop();

}
