glTranslate future problems

Newbie & Debugging Questions
#1

I’m making a scroller learning from thebennybox tutorials. In his way of scrolling he does this each loop.

public void render()
    {
       // glPushMatrix();
        {
            // draw to center (exact in this case) of screen first instead 
            // of bottom left
            glTranslatef(
              Display.getWidth() / 2 - Player.SIZE / 2, 
              Display.getHeight() / 2 - Player.SIZE / 2, 
              0); 
            sprite.render();
            // negative to scroll in opposite direction
            glTranslatef(-x, -y, 0);
        }
      //  glPopMatrix();
    }

He also calls

glLoadeIdentity();

each frame. I plan on rotating sprites later on but pushing and poping this doesn’t let it move. How can I fix this?
