week15-1_PlaySound

1.建立專案

```cpp

int main(....)

{

    PlaySound("檔名.wav",NULL,SND_ASYNC)

    ///PlaySound("C:/Do.wav",NULL,SND_SYNC);///沒有A 同步等待

}

```

補充

```cpp

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

{

    switch (key)

    {

        case '1':

            PlaySound("Do.wav",NULL,SND_ASYNC);///沒有A 同步等待

            break;

        case '2':

            PlaySound("Re.wav",NULL,SND_ASYNC);///沒有A 同步等待

            break;

        case '3':

            PlaySound("Mi.wav",NULL,SND_ASYNC);///沒有A 同步等待

            break;

```

week15-2_PlaySound_empty

1.建立專案
2.程式碼全刪除

```cpp

#include <windows.h>

#include <stdio.h>

int main()

{

    PlaySound("C:/Do.wav",NULL,SND_SYNC);

    printf("請輸入一個整數: ");

    int n;

    scanf("%d", &n);

}

```

week15-3_CMP3_MCI

1.建立專案

2.音樂檔和dll放到專案目錄，目錄改成'.'

week15-4_mouse_motion_translate_rotate

1.建立專案，貼上11行

2.目標: 能移動旋轉陣列

```cpp

#include <GL/glut.h>//¶}GLUT¥~±¾

float angleX[10]={},angleY[10]={};///陣列

float teapotX=0,teapotY=0;

void display()

{

    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);

    glPushMatrix();

        glTranslatef(teapotX,teapotY,0);

        glutSolidTeapot(0.3);

    glPopMatrix();

    glutSwapBuffers();

}

int oldX = 0,oldY = 0;

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

    oldX = x;

    oldY = y;

}

void motion(int x,int y) {

    teapotX+=(x-oldX)/150.0;

    teapotY+=(y-oldY)/150.0;

    oldX=x;

    oldY=y;

    glutPostRedisplay();

}

int main(int argc, char *argv[])

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("2024week15");

    glutDisplayFunc(display);

    glutMouseFunc(mouse);

    glutMotionFunc(motion);

    glutMainLoop();

}

```

可以旋轉

```cpp

#include <GL/glut.h>//¶}GLUT¥~±¾

#include <stdio.h>

float angleX[10]={},angleY[10]={};///陣列

float teapotX=0,teapotY=0;

void display()

{

    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);

    glutSolidSphere(0.02,30,30);

    glPushMatrix();

        glRotatef(angleX[0],0,0,1);

        glTranslatef(-0.520,-0.133,0);

        glutSolidTeapot(0.3);

    glPopMatrix();

    glutSwapBuffers();

}

int oldX = 0,oldY = 0;

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

    oldX = x;

    oldY = y;

}

void motion(int x,int y) {

    ///teapotX+=(x-oldX)/150.0;

    ///teapotY+=(y-oldY)/150.0;

    ///printf("glTranslatef(%.3f,%.3f,0);\n",teapotX,teapotY);

    angleX[0] += (x - oldX);

    oldX=x;

    oldY=y;

    glutPostRedisplay();

}

int main(int argc, char *argv[])

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("2024week15");

    glutDisplayFunc(display);

    glutMouseFunc(mouse);

    glutMotionFunc(motion);

    glutMainLoop();

}

```
