Re: BMPs again:)

[stephen healy <steven.h@e-garfield.com>]

First off thanks again everyone!  To answer the question of am i loading it each frame - I believe so yes.  I'm using one of the tutorials from www.gamedev.net under the directdraw section.  And yes i was also loading and displaying them in the same function.  Although Im not quite comfortable with threads yet i think i see what you mean by pre loading it and then drawing it once per frame.  By pre loading do you mean during init - in other words not loading it once per frame, just drawing it once per frame.  Anyways thanks for the help so far and sorry to bother you guys with such simple questions.  I'm still pretty new at writing fast games.  Simple games aren't that hard.  Its making them run fast that is hard.  So thanks everyone.
