I can't get my window to center using dbSetWindowPosition(), it always offsets the window from the center of the screen. I'm using a simple code as such:


I can find the exact values to use for centering, but I want options in my game to adjust screen size and resolution, and I don't want to store the exact values for each resolution, plus the user's screen size might be different - causing more problems.

So, why won't the window center perfectly? Is there something I'm not doing correctly? Also, where is the window registation point (for positioning)? Is it the top-left corner? Center of the window?

Thanks for any help on the subject,
-Mike

Wait... What were we talking about?

The problem is that dbScreenWidth/height() will return the size of the DBP window--the value you used with dbSetDisplayMode(). Use dbDesktopWidth() and dbDesktopHeight() instead of dbScreenWidth() and dbScreenHeight().

I was also wondering if DarkGDK had some functions for this thanks AndrewT. I had to design my own since I could not find those functions in the list. Here is what i did...

Oh, sorry about that. They were added to DBP fairly recently, however as you found out GetSystemMetrics() with a value of 0 or 1 (SM_CXSCREEN and SM_CYSCREEN accordingly) does the same thing.
