Hi all, I already opened a thread on this topic some months agò but I am not able to reply there anymore (don't know why) http://www.gamedev.net/community/forums/topic.asp?topic_id=336676&whichpage=1& Basically I am trying to make a white flash (or even a gamma or brightness increase would be good) during the games. This things should work with games like Mad dog mcree ( a laser game) that plays a movie in overlay. In the thread above someone suggested me that the best way to do this is hooking the game and manipulate the directx calls. I was finally able to hook it and cascade a call to a function (I tried with DirectDrawCreateEx). What Know ? Can I use it to accomplish my job ? Maybe I should better hook something else or something more ? I am a real noob on those kind of things but I would like to focus my time on the main project (The gun driver) so If you can avoid me a deep study of the directX call (since this is not my primary objective) I would be very happy. Thanks in advance
