剪貼程式碼到codeblocks，可以跑出茶壺

寫入函式，滑鼠點會跑出(x.y)軸座標
程式碼:
#include <GL/glut.h>
#include <stdio.h>
void display()
{
    glutSolidTeapot( 0.3 );
    glutSwapBuffers();


}
void mouse(int button, int state, int x, int y)
{
    /// mouse函式: 左中右鍵, DOWN/UP, X座標, Y座標
    printf("%d %d %d %d\n",button, state,x,y);
}
int main(int argc, char**argv)
{
    glutInit(&argc,argv);
    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);
    glutCreateWindow("Week03");

    glutDisplayFunc(display);
    glutMouseFunc(mouse);
    glutMainLoop();

}

唉呦厲害啦!跑出了一個很牛B的茶壺我怎麼點他就怎麼跑,明顯是個狠角色

程式碼:

#include <GL/glut.h>

#include <stdio.h>

float teapotX=0, teapotY=0;

void display()

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glPushMatrix();

        glTranslatef(teapotX, teapotY, 0);

        glutSolidTeapot( 0.3 );

    glutSolidTeapot( 0.3 );

    glPopMatrix();

    glutSwapBuffers();

}

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

{

    /// mouse函式: 左中右鍵, DOWN/UP, X座標, Y座標

    printf("%f %f\n",(x-150)/150.0, (y-150)/150.0);

    teapotX= (x-150)/150.0;

    teapotY= -(y-150)/150.0;

}

int main(int argc, char**argv)

{

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("Week03");

    glutDisplayFunc(display);

    glutMouseFunc(mouse);

    glutMainLoop();

}
