主題: 聲音、音效、音樂

1. 實作: 播放 WAV檔

#include <windows.h>
#include <mmsystem.h>
int main()
{
    ///                    檔名                     /   空      /聲音同步
    PlaySoundA("thunder_clap.wav",NULL,SND_SYNC);

}

#include <windows.h>
#include <mmsystem.h>
void display()
{
    
}
void keyboard(unsigned char key,int x,int y)
{                                          
             ///ASYNC表示不等音檔播完直接播下一個
    if(key=='1')PlaySoundA("do.wav",NULL,SND_ASYNC);
    if(key=='2')PlaySoundA("me.wav",NULL,SND_ASYNC);
    if(key=='3')PlaySoundA("fa.wav",NULL,SND_ASYNC);
    if(key=='4')PlaySoundA("so.wav",NULL,SND_ASYNC);
}
int main(int argc, char** argv)
{
    glutInit(&argc,argv);
    glutInitDisplayMode(GLUT_DEPTH | GLUT_DOUBLE);
    glutCreateWindow("week12");
    glutDisplayFunc(display);
    glutKeyboardFunc(keyboard);
    glutMainLoop();
}
2. 實作: 播放 MP3檔

#include <windows.h>
#include <mmsystem.h>
#include <GL/glut.h>
#include "CMP3_MCI.h"///記得加入CMP3_MCI.h檔到同一個專
CMP3_MCI mp3;               案目錄

int main(int argc, char** argv)
{
    mp3.Load("四月.mp3");
    mp3.Play();
    glutInit(&argc,argv);
    glutInitDisplayMode(GLUT_DEPTH | GLUT_DOUBLE);
    glutCreateWindow("week12");
    glutDisplayFunc(display);
    glutMainLoop();

}

*合弦


#include <windows.h>
#include <mmsystem.h>
#include <GL/glut.h>
#include "CMP3_MCI.h"
CMP3_MCI mp3;
CMP3_MCI Do,Re,Mi,Fa;
void display()
{


}
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();
    ///讓按鍵同時按能夠和弦
}
int main(int argc, char** argv)
{
    Do.Load("do.wav");Re.Load("re.wav");
    Mi.Load("mi.wav");Fa.Load("fa.wav");
    mp3.Load("四月.mp3");
    glutInit(&argc,argv);
    glutInitDisplayMode(GLUT_DEPTH | GLUT_DOUBLE);
    glutCreateWindow("week12");
    glutDisplayFunc(display);
    glutKeyboardFunc(keyboard);
    glutMainLoop();

}
3.GLUT .cbp 專案檔 的設定 (執行目錄、include/lib目錄、link lib檔)



然後將freeglut檔內bin檔的freeglut.dll及音檔丟入專案檔內
*音樂添加圖形發出聲音

球碰撞到邊界會發出音樂
#include <windows.h>
#include <mmsystem.h>
#include <GL/glut.h>
#include "CMP3_MCI.h" /// TODO3: 雙引號,在專案同一個目錄裡
CMP3_MCI mp3;///ex. int a; TODO3: 宣告一個物件變數,叫 mp3
CMP3_MCI Do, Re, Mi, Fa, So; ///TODO4: 有5個物件變數

float ballX=0, ballY=0, dx=0.05, dy=0.03;///ballX會加上dx, ballY會加上dy
void display()
{///想法: 可不可以做個小遊戲....有個球,會動來來動
    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
    glPushMatrix();///TODO6: 備份
        glTranslatef(ballX, ballY, 0);///TODO6: 移到ballX,ballY
        glutSolidSphere(0.1, 30,30);///TODO6:圓球
    glPopMatrix();///TODO6:還原
    glutSwapBuffers();
}
void timer(int t)///TODO6: timer
{
    glutTimerFunc(50, timer, t+1);///TODO6: 用timer
    ballX+=dx; ballY+=dy;///TODO6: 球會動
    if(ballX>=1){
        Do.Play(); dx= -dx;
    }
    if(ballX<=-1){
        Re.Play(); dx= -dx;
    }
    if(ballY>=1){
        Mi.Play(); dy= -dy;
    }
    if(ballY<=-1){
        Fa.Play(); dy= -dy;
    }
    glutPostRedisplay();///TODO6: 重畫畫面
}
void mouse(int button, int state, int x, int y)///TODO6: mouse會有槍聲
{
    if(state==GLUT_DOWN) PlaySoundA("shot.wav", NULL, SND_ASYNC);
}
void keyboard(unsigned char key, int x, int y)
{                                 //不要同步,不等結束,繼續
    if(key=='1') Do.Play();///TODO4 PlaySoundA("do.wav",NULL,SND_ASYNC);
    if(key=='2') Re.Play();///TODO4//PlaySoundA("re.wav",NULL,SND_ASYNC);
    if(key=='3') Mi.Play();///TODO4//PlaySoundA("mi.wav",NULL,SND_ASYNC);
    if(key=='4') Fa.Play();///TODO4//PlaySoundA("fa.wav",NULL,SND_ASYNC);
    if(key=='5') So.Play();///TODO4//PlaySoundA("so.wav",NULL,SND_ASYNC);
}///TODO4: 上面的程式, 現在可以有合弦 (ex. Do+Mi+So => 只會有個音出來...)
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");///TODO4: 5個物件變數 設好檔案
    mp3.Load("music.mp3");///TODO3:
    ///mp3.Play();///TODO3:
    glutInit(&argc, argv);
    glutInitDisplayMode(GLUT_DOUBLE |GLUT_DEPTH);
    glutCreateWindow("week12 sound");
    glutDisplayFunc(display);
    glutKeyboardFunc(keyboard);///TODO2:鍵盤有函式
    glutTimerFunc(50, timer, 0);///TODO6
    glutMouseFunc(mouse);///TODO6
    glutMainLoop();
