Week 07

• 用基本的 printf 顯示出按下鍵盤確定有效果

• 加入標頭檔 使音效可以使用
• 在按下keyboard 觸發音效 及印出字串

#include <GL/glut.h>

#include <stdio.h>

#include <mmsystem.h>

void display()

{

    glutSolidTeapot(0.3);

    glFinish();

}

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

{

    if(key=='a')

    {

        PlaySound("rocket.wav",NULL,SND_ASYNC);

        printf("小心!!! 火箭來囉~~~\n");

    }

}

 int main(int argc,char** argv)

 {

     glutInit(&argc,argv);

     glutCreateWindow("hello");

     glutDisplayFunc(display);

     glutKeyboardFunc(keyboard);

     glutMainLoop();

 }

• 利用音效檔做出 piano 的模擬器

#include <GL/glut.h>

#include <stdio.h>

#include <mmsystem.h>

void display()

{

    glutSolidTeapot(0.3);

    glFinish();

}

{

    if(key=='a')

    {

        PlaySound("rocket.wav",NULL,SND_ASYNC);

        printf("小心!!! 火箭來囉~~~\n");

    }

    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);

}

 int main(int argc,char** argv)
