 week13-1_keyboard_angleID_mouse_motion_angle

複製12-3的程式碼改檔名

新增了

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

    if(key=='0') angleID = 0;

    if(key=='1') angleID = 1;

    if(key=='2') angleID = 2;

    if(key=='3') angleID = 3;

}

void motion (int x,int y){

    angle[angleID] = y;

    glutPostRedisplay(); 

}

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){

    angle[angleID] +=y-oldY;

    oldX= x;

    oldY=y;

    glutPostRedisplay(); ///貼上便利貼，提醒glut要重畫畫面

}
