      • Hello all, I'm starting to get to grips with the structure of things, but through all the code I've looked at, all the tutorials etc etc, I'm still not clear on a few things. I've searched these forums pretty exhaustively, but I'll issue the obligatory pre-emptive apology if I've missed something obvious. Now, to start with, I believe I'm correct in saying that camera position must be set vi

      • I'm using a custom ContentImporter to take a custom model format and convert it to NodeContent root that is then written out by the default writer. It works great - it takes my file, say Assets/Foo/Bar.xxx, and spits out Assets/Foo/Bar.xnb. My problem lies with the external references I create (in this case textures, but I'm sure it would apply to effects and such) - they do not get put where I

Since there are several .NET 2.0 compatible compilers out there shouldn't this contest allow these entries as well as they can use both the Windows and XBox 360 XNA assemblies. Just to clarify, I ha

      • Hi, I can create a device and a swap chain with D3D10CreateDeviceAndSwapChain(). To get a suitable device a render target format can be specified in the buffer description. This seems to be equal to a CreateTexture2D() call. To create the render target view later, we can get the buffer or the buffers we created with GetBuffer() from the SwapChain.
