新增一個專案week11-1_keyboard

在程式碼裡找keyboard

找glutKeyBoard(keyboard)

#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==27)exit(1234);

 }

 int main(int argc,char**argv)

 {

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);

    glutCreateWindow("week11");

    glutDisplayFunc(display);

    glutKeyboardFunc(keyboard);

    glutMainLoop();

 }

1-2

再結合播放音樂,新增專案week11-2_keyboard_PlaySound

#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("C:\\Users\\Administrator\\Desktop\\do-re-mi\\do.wav",NULL,SND_ASYNC);

    if(key=='2') PlaySound("C:\\Users\\Administrator\\Desktop\\do-re-mi\\re.wav",NULL,SND_ASYNC);

    if(key=='3') PlaySound("C:\\Users\\Administrator\\Desktop\\do-re-mi\\mi.wav",NULL,SND_ASYNC);

 }

 int main(int argc,char**argv)

 {

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);

    glutCreateWindow("week11");

    glutDisplayFunc(display);

    glutKeyboardFunc(keyboard);

    glutMainLoop();

 }

按下數字1會出現do的聲音,2是re,3是mi

2-1

縮短路徑

PlaySound("C:\\Users\\Administrator\\Desktop\\do-re-mi\\do.wav",NULL,SND_ASYNC);

改成

PlaySound("do-re-mi/do.wav",NULL,SND_SYNC);

2-2

新增專案week11-4_CMP3_MCI_LOAD_PLAY

不改變原本的程式碼,新增圖2框起來的程式碼

3-1

註解char filename[]="C:/Users/Administrator/Desktop/do-re-mi/suzume.mp3";

新增myMP3.Load("suzume.mp3");

把下載的音樂跟freeglut-bin-freeglut.dll放到專案4

去project-properties-build target把excution working dir位置縮減成小數點   .

3-2

第4個專案裡, .dll檔因為gitignore會把它忽略,所以去2023graphicsb裡的gitignore用notepad++修改,把.dll註解調(打#)
