Week 11 陳映心

課堂作業 1: 利用codeblock播放音檔

1. 開啟一個貝殼專案

2. 把下載好的音檔放入專案資料夾中

3. 程式碼

執行失敗 : 因為沒有寫link

#include <iostream>

#include <windows.h>

#include <mmsystem.h>

using namespace std;

int main()

{

    cout << "Hello world!" << endl;

    PlaySoundA("Do.wav", NULL, SND_SYNC);///SND_SYNC : 同步

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

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

    return 0;

}

 4. Build options 

5. Linker settings -> add "winmm"

6. 執行成功

課堂作業2 : 用freeglut的keyboard彈出聲音

1. Build options -> Linker settings -> add"freeglut、opencv32、glu32、gid32、winmm"

 2. 設定include目錄

(1)freeglut.include位置

(2)c:\opencv2.1\include

3.設定link目錄

(1)freeglut.lib位置

(2)c:\opencv2.1\lib

4. 程式碼

#include <GL/glut.h>

#include <windows.h>

#include <mmsystem.h>

void display()

{

    ///空白(不做事)

}

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);

}

int main(int argc, char**argv)

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("3D and Sound");

    glutDisplayFunc(display);

    glutKeyboardFunc(keyboard);

    glutMainLoop();

    return 0;

}

 5. 執行 : 失敗 因為沒有放入freeglut.dll檔

6. 把freeglut.dll檔放進專案資料夾

7. 執行 : 成功

課堂作業3 : 播放mp3音檔+利用滑鼠按鍵觸發音檔+圖片移動

1.  將CMP3_MCI.h檔放入專案資料夾

2. 程式碼

#include <GL/glut.h>

#include <windows.h>

#include <mmsystem.h>

#include "CMP3_MCI.h"

CMP3_MCI player;

float potx=-1, poty=0;

void display()

{

    glClearColor(0.5, 0.5, 1, 1);

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glPushMatrix();

        glTranslatef(potx, poty, 0);

        glutSolidTeapot(0.1);

    glPopMatrix();

    glutSwapBuffers();

}

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

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

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

}

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

{

    if (state==GLUT_DOWN)

    {

        PlaySoundA("Si.wav", NULL, SND_ALIAS);

    }

}

void timer(int t)

{

    glutTimerFunc(30, timer, t+1);

    potx+=0.03;

    if (potx>1)potx=-1;

    glutPostRedisplay();

}

int main(int argc, char**argv)

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("3D and Sound");

    glutDisplayFunc(display);

    glutKeyboardFunc(keyboard);

    glutTimerFunc(30, timer, 0);

    glutMouseFunc(mouse);

    player.Load("youkai.mp3");

    player.Play();

    glutMainLoop();

    return 0;

}

3. 將音樂檔放入專案資料夾 

4. 執行程式 : 成功
