I''m drawing 2D sprites using an orthographic projection matrix in dx8, but I can''t get the z-buffering to work. I''ve enabled z-buffering, but whatever z values I give sprites, the more recently created sprites appear on top of ones created before them. Is there something I''ve missed or doesn''t the z value work with an orthographic projection? thanks

Ortho as far as I know (I use Opengl) does not have a Z buffer when you use ortho its 2d so therefore whatever you draw last will appear on the top and whatever you draw first will appear underneath
