      • Hello. I started working on a video game as a hobby a couple months ago, and I was doing it in Java because that's what I was most experienced with. Since stumbling across XNA on the web, I've just started it over again in C#, because XNA makes so many things easier. So thanks for making such a good and free product. I figured you guys would be happy to hear that an experienced Java programmer is

Problem: Whenever I load a model into my game that has been exported using the latest .fbx exporter plugin from Maya the model is arranged such that some of the pieces of the model are lined up along its x axis.

      • Now I know XNA is supposed to be for game development, but its ease of use should also allow for very simple screen saver programming. In only a few hours I've got a completely working version of the Windows Starfield screen saver up and running, and I'm sure other people here could come up with stuff that's a ton more creative than that. What would be hard about turning these into completely work

      • Great work on XNA GSE 1.0! I downloaded it today and signed up for the 360 Creator's Club. Getting the basic engine code I've been working on under Windows for the past few weeks compiling and running on 360 was far easier than I was expecting (though it would be nice if the IDE had better support for projects that target both platforms). One aspect of the engine I've been avoiding for a while

      • I have a fairly simple problem. I'd like to see if the screen is wider than 1280 or not, before deciding on a 1280x720 backbuffer or a 1024x640 backbuffer. The latter will make the game (in windowed mode) work better on 1280x800 or 1280x1024 displays, which are pretty darn common these days. (Meanwhile, for Xbox, I'll just hard-code 1280x720) However, when I create the graphics device manager insi
