Week12 - 07161045

聲音、音效、音樂(WAV檔)

• 先開啟GLUT專案
• 把程式碼都刪掉
• 上網下載任一WAV檔音樂，將音樂放到freeglut裡的bin
• 輸入以下程式碼:

#include <windows.h>

#include <mmsystem.h>

int main()

{

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

}

• 上述程式碼藍色部分為音檔名稱

     

• 利用上面程式做出小星星

     

• 利用數字鍵彈鋼琴
• 程式碼如下:

#include <windows.h>

#include <mmsystem.h>

#include <GL/glut.h>

void display()

{

}

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

{

    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);

    if(key=='6') PlaySoundA("la.wav", NULL, SND_ASYNC);

    if(key=='7') PlaySoundA("si.wav", NULL, SND_ASYNC);

}

int main(int argc, char**argv)

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("07161045");

    glutDisplayFunc(display);

    glutKeyboardFunc(keyboard);

    glutMainLoop();

}

     

聲音、音效、音樂(MP3檔)

• 先到Moodle下載老師給的"CMP3_MCI.h"，可讓電腦播MP3/WMA 音檔
• 將"CMP3_MCI.h"拉至桌面程式碼所在的資料夾裡
• 上網下在任一首mp3，拉至freeglut裡的bin
• 程式碼如下:

#include <windows.h>

#include <mmsystem.h>

#include <GL/glut.h>

#include "CMP3_MCI.h"

CMP3_MCI mp3;

void display()

{

}

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

{

    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);

    if(key=='6') PlaySoundA("la.wav", NULL, SND_ASYNC);

    if(key=='7') PlaySoundA("si.wav", NULL, SND_ASYNC);

}

int main(int argc, char**argv)

{

    mp3.Load("twice.mp3");

    mp3.Play();

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("07161045");

    glutDisplayFunc(display);

    glutKeyboardFunc(keyboard);

    glutMainLoop();

}

     

• 利用五個變數加上和弦
• 程式碼如下:

#include <windows.h>

#include <mmsystem.h>

#include <GL/glut.h>

#include "CMP3_MCI.h"

CMP3_MCI mp3;

CMP3_MCI Do, Re, Mi, Fa, So;

void display()

{

}

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

{

    if(key=='1') Do.Play();///PlaySoundA("do.wav", NULL, SND_ASYNC);

    if(key=='2') Re.Play();///PlaySoundA("re.wav", NULL, SND_ASYNC);

    if(key=='3') Mi.Play();///PlaySoundA("mi.wav", NULL, SND_ASYNC);

    if(key=='4') Fa.Play();///PlaySoundA("fa.wav", NULL, SND_ASYNC);

    if(key=='5') So.Play();///PlaySoundA("so.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");

    mp3.Load("twice.mp3");

    mp3.Play();

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("07161045");

    glutDisplayFunc(display);

    glutKeyboardFunc(keyboard);

    glutMainLoop();

}

     

• 將freeglut裡bin的資料拉至桌面程式碼所在的資料夾裡

     

• 再把"week12_07161045.cbp"用notepad++開啟，將兩個地方雙引號內改為"."

     

• 利用程式碼讓球碰到牆壁回彈，碰到牆壁發出Do、Re、Mi、Fa、So的聲音
• 再加上滑鼠程式碼(槍聲)
• 程式碼如下:

#include <windows.h>

#include <mmsystem.h>

#include <GL/glut.h>

#include "CMP3_MCI.h"

CMP3_MCI mp3;

CMP3_MCI Do, Re, Mi, Fa, So;

float ballX=0, ballY=0, dx=0.05, dy=0.03;

void display()

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glPushMatrix();

        glTranslatef(ballX, ballY, 0);

        glutSolidSphere(0.1, 30, 30);

    glPopMatrix();

    glutSwapBuffers();

}

void timer(int t)

{

    glutTimerFunc(50, timer, t+1);

    ballX+=dx; ballY+=dy;

    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();

}

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

{

    if(state==GLUT_DOWN) PlaySoundA("bar.wav", NULL, SND_ASYNC);

}

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

{

    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);

    if(key=='6') PlaySoundA("la.wav", NULL, SND_ASYNC);

    if(key=='7') PlaySoundA("si.wav", NULL, SND_ASYNC);

}

int main(int argc, char**argv)

{

    mp3.Load("twice.mp3");

    mp3.Play();

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("07161045");

    glutDisplayFunc(display);

    glutKeyboardFunc(keyboard);

    glutTimerFunc(50, timer, 0);

    glutMouseFunc(mouse);

    glutMainLoop();
