02160074_張凱晴 week07

本周重點：Keyboard、Mouse

1.Keyboard

2.增加音效：先下載一個音檔，放到 freeglut ->bin 資料夾裡

3.增加程式，當按下 a 的時候，發出聲音

4.找音階的單音檔，就可以做出

音階

5.Mouse 

glutSpecialFunc(special);//glut的SpecialFunc 可以用F1~F12 & 上下左右 &Ctrl.....等等

程式碼如下：

#include <GL/glut.h>

#include <stdio.h>

#include <mmsystem.h>

float teaY=0,rotX=0,rotY=0,oldX=0,oldY=0;

void display()

{

    glClear(GL_COLOR_BUFFER_BIT);

    glPushMatrix();

    glTranslatef(0,teaY,0);

    glRotatef(rotX,1,0,0);

    glRotatef(rotX,0,1,0);

    glColor3f(0,0.5,0.8);

    glutSolidTeapot(0.3);

    glPopMatrix();

    glFlush();

}

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

{

    if(key=='1') PlaySound("Do.wav",NULL,SND_ASYNC);

    if(key=='2') PlaySound("Re.wav",NULL,SND_ASYNC);

    if(key=='3') PlaySound("Mi.wav",NULL,SND_ASYNC);

    if(key=='4') PlaySound("Fa.wav",NULL,SND_ASYNC);

    if(key=='5') PlaySound("Sol.wav",NULL,SND_ASYNC);

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

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

}

void special(int key,int x,int y)

{

    if(key==GLUT_KEY_DOWN){ 

        teaY-=0.1; printf("down\n"); 

    }

    else if(key==GLUT_KEY_UP){

        teaY+=0.1; printf("up\n");

    }

    glutPostRedisplay();

}

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

{

    oldX=x; oldY=y;

    if(GLUT_LEFT_BUTTON==button && GLUT_DOWN==state) printf("left down\n");

    if(GLUT_RIGHT_BUTTON==button && GLUT_DOWN==state) printf("right down\n");

}

void motion(int x,int y)

{

    rotX+=y-oldY;

    rotX+=x-oldX;

    oldX=x; oldY=y;

    glutPostRedisplay();

}

int main(int argc,char**argv)

{

    glutInit(&argc,argv);

    glutCreateWindow("02160074");

    glutDisplayFunc(display);

    glutKeyboardFunc(keyboard);

    glutSpecialFunc(special);

    glutMouseFunc(mouse);

    glutMotionFunc(motion);

    glutMainLoop();

}
