05160461_廖柏宇 第一次上課筆記在blog Week03(滑鼠、鍵盤)

複習(自己重頭打一次):




同學問題解決精華:


主題:滑鼠、鍵盤
part01


button 滑鼠按鍵(左中右鍵)→0=左鍵、1=中、2=右
state(滑鼠點放)→0=按下、1=放開




程式碼
#include <GL/glut.h>
void display()
{
    glClearColor(1, 1, 0, 1);
    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
    glColor3f(0, 1, 0);
    glutSolidTeapot(0.3);

    glutSwapBuffers();a

}

#include <stdio.h>
void mouse(int button, int state, int x, int y)
{
    //printf("%d %d %d %d\n", button, state, x, y);
    if(state==GLUT_DOWN) printf("glVertex2f(%f, %f);\n", (x-150)/150.0, (y-150)/150.0);
///當滑鼠點擊時
}

int main(int argc, char**argv)
{

    glutInit(&argc, argv);
    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);
    glutCreateWindow("week03");

    glutDisplayFunc(display);
    glutMouseFunc(mouse);
    //glutMouseFunc(motion);

    glutMainLoop();
}

Part2加入滑鼠移動






程式碼
#include <GL/glut.h>

float teaportX=0, teaportY=0;

void display()
{
    //glClearColor(1, 1, 0, 1);
    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
    glPushMatrix();
        glTranslatef(teaportX, teaportY, 0);
        glutSolidTeapot(0.3);
    glPopMatrix();
    glutSwapBuffers();

}

#include <stdio.h>
void mouse(int button, int state, int x, int y)
{
    //printf("%d %d %d %d\n", button, state, x, y);
    if(state==GLUT_DOWN) printf("glVertex2f(%f, %f);\n", (x-150)/150.0, (y-150)/150.0);
}

void motion(int x, int y)
{
    teaportX=(x-150)/150.0;  teaportY=-(y-150)/150.0;
    printf("%d %d\n", x, y);
    glutPostRedisplay();
}

int main(int argc, char**argv)
{

    glutInit(&argc, argv);
    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);
    glutCreateWindow("week03");

    glutDisplayFunc(display);
    glutMouseFunc(mouse);
    glutMotionFunc(motion);

    glutMainLoop();
}
