      • Greetings, I followed the second XNA tutorial, and got to creating a scrolling background for the space ship program. My problem is that as soon as I added the code from the tutorial for the scrolling background, the space ship became somewhat transparent, meaning that I am not seeing it like a solid rather a sum total of spheres and other geometries. For example, I can now see the 4 spheres on th

  • Volume textures!

      • There is Texture3d, but the content pipeline doesn't support volume textures. That's great! Now the main thing I wanted to do with XNA can't be done because volume textures aren't supported. More and more it feels as if this product should've had one more round in a beta cycle. That or they have to get XNA 1.1 out the door soon! Wonderful API, but it needs some polish.

      • I'm having a big problem on moving vertices with the mouse. Using the Vector3.Unproject, automaticly sets the Z coordinate for a point (the distance from camera)(in my case to 7). When I set the Z coordinate of a vertex to 2, it's not on the same position on the screen as the mouse is. How do I unproject a Vector without modifying it's Z coordinate, but the Vector coordinate to look on the screen

However, I am having trouble figuring out how to detect the collision between two objects. Say for example, two bouncing balls in a 2D game. How can I detect the collision of this two objects I imagine it has something to do with sine and cosine T

I had everything working in the code, and then I decided to port it over to the ContentPipeline. (I'm liking the pipeline more and more now). Long story short, I've run into a few nasty bugs introduced while trying to improve my code. I've found debugging to be a

Right now it appears that the Alpha Shading does not take into account Z buffering, and instead Alpha Shading is done in the order that the object is drawn (yes, my shading is set for sourceAlpha and inverseSourceAlpha.) For example, if i have a backgroun
