Moving an object towards x-axis

OpenGL
1

Hello,i am a very beginner and iam trying to make movement of a character in a scene,i tried making this by using gltranslatef(),but when use this function the charecter will disaapear.
I am posting my code below please correct my mistakes.and my character is a rectangle now.i am using keyboard function to move character.


int main( int argc,char **argv)
{
   glutInit(&argc,argv);
   glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);
   glutInitWindowSize(1000,1000);
   glutCreateWindow("Nakkur's Village");
   glutKeyboardFunc(myKey);
   glutDisplayFunc(display);

  //glutTimerFunc(1000,mytimer,0);

   glutMainLoop();
  return 0;
}

void display()
{
glClear(GL_COLOR_BUFFER_BIT);
glLoadIdentity();
gluOrtho2D(-1000,1000,-1000,1000);

        nyt();
        wall();
        mountain();
        house();
        //movenakkur(cx);

        tree();
        blinkstars();
        moon();

        glPushMatrix();
        glTranslatef(k,0,0);
        cloud();
        cloud1();
        cloud2();
        k+=100;
        glutPostRedisplay();
        glPopMatrix();


glFlush();
glutSwapBuffers();

This isn’t a debugging service. Please read the Forum Posting Guidelines.

What have you done to try and debug the problem yourself? Do you have any specific OpenGL-related questions you’d like to ask?
