      • Hello, I just wrote a little puzzle game (Windos Game Project) and now I want to build the 360 version of it, but I have a little problem (probably PEBKAC *g*) I wrote a content-processor for instanced rendering (overriding ModelProcessor) and implemented a new ContentItem called 'Font'. It reads the *.fnt files from AngelCode Bitmapfont Converter. Because I want to reuse this, I put i

      • Hi, I have just downloaded the Feb 2007 DirectX SDK, prior to this I was using the April 2007 SDK. I choose full download and selected the Redistributable option as well. The download was succesful. I have now come to compile a Windows / DirectX application which was previously compiling error free. I noticed the Include Directories section had been wiped clean so I added the new Dir

      • I have a problem with loading a model with bone animation. I created two simple boxes with 3ds max and a simple bone animation. Then I exported this object as fbx and with the panda exporter as x file as well. When I try to load any of these models in my xna project, I get the following error: Error 1 Building content threw ArgumentOutOfRangeException: Specified argument was out of the ran

      • Hey, I am trying to understand how animations works in XNA. I have modified the content processor to get the vertex buffer of a mesh from a model in a raw data, and I believe that it is in the vertex buffer where the skin weights indices of each vertex for each bone is stored. Does anyone has some clue how to get the skin weights or how they are stored in the vertex buffer Or even bet

I tried a PING to the IP Address of my XBox 360 and it fails. So i checked the Subnet, the IP Address, everything looks fine. And than i figured out something really strange: I started "PING -t 192.168.0.2"

      • A question for the framework/VM guys... I have ported one of my simpler benchmarks to the 360, and find that the numeric performance is running 5x slower than my 2.8GHz P4 desktop. Now I was expecting a drop in performance on the 360, allowing for the difference in CPU implementation (in order execution / branch prediction etc), but nothing like this magnitude! The benchmark simply transform

      • Hi All, I have some test code that uses BoundingBox.Contains to see if a vector lies inside the bounding box. It works fine until I transform the point vector and bounding box min/max vectors by a matrix. The coordinates look right, but the function retuns disjoint. I know I must be missing something here, but I can't figure it out. The values after translation are: BoundingBox.Min: 0, 0,

      • Hi, Is there a way to share source files between projects in GSE 1.0 We have now 2 projects for our game, 1 for pc, 1 for the 360, but when I add an existing pc-source file in the 360 project it makes a copy of it and doesn't use the original one. This makes it somewhat more troublesome to keep both projects up to date. Cheers, Maurice

      • Currently volume textures aren't supported in the Content Pipeline. So if I have a mesh that references a volume texture it will fail compiling. So, is it just a matter of writing a custom importer for volume dds files or is it all the way through the pipeline Will ContentManager.Load<Texture3d>(...) work if I just write the importer Say it is so...it is Christmas after all :-)

      • Hey all - I've been working on segmenting a polygon to some arbitrary complexity. When I first encountered this problem, I took in an array of Vector2[]'s, computed the centroid, and walked the outside, generating a list of polygons to draw triangle lines from the centroid to. ( I walked the outside with Bresenham's Line Algorithm ) However, this isn't really going to solve the problem for me - i

  • Implications of Keyboard.GetState() returning a KeyboardState structure.

      • The KeyboardState object is a C# structure - meaning that it's a value type not a reference type. Calling Keyboard.GetState() returns a copy of the KeyboardState structure. This KeyboardState structure appears to be about 32 bytes in size - determined via a call to System.Runtime.InteropServices.Mashal.SizeOf(). Is there a particular reason why KeyboardState is a structure rather than a class type

The problem is that in full screen mode the fps counter shows me 75; it seems that update() is being forced to 75hz somehow, while my tft drops back to the 60hz it can handle....this results in all sprite movement becoming ver

So I decided not to migrate from MDX to XNA though I want to do that very much. I feel like MDX 2 more; amen to MDX 2. The hardest issue for me is the content pipeline, which is very necessary, but the workflow is fixed and it assumes the c
