      • Hello all I'm just starting developing games and am wondering which language / envirronment to write them in. At the moment for experimenting using Direct3D I'm using C#, with Visual Studio 2005 (.NET), and mucking around with DirectX 9, and XNA (the XNA game studio express). I've always figured that the professional game devs use unmanaged C++, but is that changing now with the a

      • Hi All, I've just started a new series of XNA demos on my website. So far I have 3 demos: XNA Per-Pixel Lighting Demo, XNA Normal Mapping Demo, and XNA Parallax Normal Mapping Demo. I haven't included any pre built executables with the demos, so you'll have to build them yourself from the source provided with each demo. The demos target the Windows platform, but should run with little or no

Here's my code. [code] //this is what m_pVB and m_pIB are set to in the class //LPDIRECT3DVERTEXBUFFER9 *m_pVB; //LPDIRECT3DINDEXBUFFER9 *m_pIB; //VBNum = The number of buildings / the defined number of building

      • I want to use a single instance of Texture2D and a single bitmap image for a skybox. The image contains six smaller images that represent the skybox panels. If I use values between 0 and 1 for the texture coordinates, they seem to get rounded. Is there anyway I could use a texture sheet and use values between 0 and 1 as the texture coordinates, or do I have to create an instance of Texture2D every

      • Hello everyone, I've been playing around with XNA for a while now, and I can't seem to get the lightning right on a mesh i'm dynamically creating. I've created a simple GameComponent that initializes a VertexBuffer and an IndexBuffer in the LoadGraphicsContent method. The Draw method uses a BasicEffect (with default lightning enabled) to draw the vertices using the TriangleList primitive. I

Everyone knows how the game works so it's pretty much a great place to start, but unfortunately for me, I don't like using other peoples code. I always prefer to read it, re-code it and start from scratch. The problem I faced was I ran out of coffee, and couldn'

I can't see how any companies would be willing to switch to managed code for prime time games as long as MSIL can be easily reverse engineered. I love XNA and Managed code and pray that eventually commercial industry will as well (so I can put my C# skills towards gaming instead of business apps). Our company is alrea

I need to have, for lack of a better term, a popup window to give the player feedback, and accept his/her decisions. If I was writing the game using GDI I'd just use a dialog box, but XNA can't do that. I really don't want to go the Space

      • 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.
