      • I have a question about the dbp challenge. My xbox360 has just fallen prey to the dreaded " three flashing red lights on the ring of light " issue and, I suspect, will have to be sent in for service. I'm working with support and awaiting their response, but that's not really the issue. I really really wanted my game to be cross platform such that the same code-base built for both windows

      • My game uses a collision detection method from the collision detection turitorial from Ziggyware.com. Basically it compares the pixel data of two spirtes to detect collision. This collision detection method has worked great with the exception of when I flip the image horizontally. And that's where my problem is. The method gets all the pixel data from a texture and copies it into an array w

It seems CreateDIBSection only works on 256 colors lpbi->bmiHeader.biBitCount = 8; lpbi->bmiHeader.biCompression = BI_RGB , which means I have to convert the 16bit pixel to 8 bits.

When I call graphics.GraphicsDevice.Present() (assuming "graphics" is my GraphicsDeviceManager object), it causes flickering in fullscreen mode. If I don't call Present(), no flickering occurs, and everything seems to be displayed properly, but when I call Present(), there is white

I know how to set the textures of the front and back of the card independently now, but I don't know how I can use a single texture sheet (comprising of 52 fronts of cards and a few back face images) in this process. The BasicEffect takes a Texture2D format for the texture, and of course setting it to a single texture image is fine. But how to set th

So I decided not to migrate from MDX to XNA though I want to do that very much. I feel like MDX 2 more; amen to MDX 2. The hardest issue for me is the content pipeline, which is very necessary, but the workflow is fixed and it assumes the c
