      • I've done the Going Beyond tutorial shown in the videos posted on the XNA team blog, and I noticed I was getting weird artifacts on the spaceship model. I went ahead and did another tutorial, this time using a 2D sprite, and there were also artifacts on the sprite. The artifact looks like one or more jagged transparent spikes, jutting out from the sides of the model or sprite. They're kinda hard t

      • I am drawing my sprites using a single texture and cutting them with the sourcerect feature, however, this causes my screen to flicker if I move the sprites using a float number with decimals, because they have to be converted to (int). My question is: Is it possible to draw(even if having to code a new batch class) using a different struct other than Rectangle that uses floats instead of ints

      • Hi guys. This is kinda a newbie question that I hope someone can nail for me. What exactly is the purpose of the DepthStencilBuffer. I'm using it to render a shadowmap into a rendertarget, but I need to know exactly why it's needed. The code doesn't seam to use it. Another thing I would love to know is why I'm not able to save the content of a rendertarget2D with Single format to a file.

      • According to the docs found in the December SDK for the page "D3DXSHADER Flags" in order to enable compiling via D3DX of HLSL ps_1_x profiles, we must include d3dx_31.dll in our distribution. To the best of my knowledge, the EULA forbid redistributing D3DX DLL files. This is based on the discussion on the DXDev mailing list a while back. What is the solution for this -Pat

Draw I know there are benefits to multithreading an application but am unsure how to apply that to game design. I'm stuck on the idea that you need to complete all your updates for game state, running scripts, and so on, before you move on to drawing. The only benefit to multithreading during the U
