      • As seen in these two screenshots, Glitch 1 Glitch 2 In reality, I don't know what's even happening to my vertices. This doesn't happen from the beginning of the program execution, it happens randomly during the execution about a few minutes into running it. Once it happens, it will happen more frequently and sooner during the program execution when I re-compile and run.I just don't have a name

So I downloaded SP1, but when I try to apply that it gives me an error along the lines of having a bad version. I have version 8.0.5 of visual c# express 2005, running along-side visual studio 2005.

      • With all the great new offerings out or coming soon for the 360: XBox Live Video Marketplace, XNA game creation, and the recently announced IPTV, the poor little 20GB hard drive's days look numbered. Is MS planning to release a larger hard drive for the 360 I'm pretty sure that many people (including myself) would be very interested in one.

      • I was surprised to find out that XNA doesn't work in Internet Explorer as a WinForm Control. I know I must be smoking crack, but somewhere a long the line I got the impression that XNA would enable a 3D environment in Internet Explorer. If we can put Ink on the Web, http://www.code-magazine.com/Article.aspx quickid=0512062 , then I think we should be able to put a 3D environment on the web as well

Because they are structs they don't derive from a base class other than ValueType. If I use ValueType as the parameter I don't have access to the propertys of the vertex. Is this a case where refelection would be usefull C

I implemented a lot of mechanics for my game, but I need greater interaction to proceed development in a sane manner. So far I've just implemented the text drawing stuff from scratch.

Is there anyway to do this with minimal code, because without this it's hard to make any games . One thing I do know is that for axis-aligned walls, it's easier to use BoundingBoxe
