    - Animation sample? Thanks for the link but that component is LGPL licenced and given the way the linking for C#/GSE works (at least when supporting the 360 where we can't deploy libraries as DLLs) the LGPL is pretty much the same as if it were GPL, practically speaking. I'll keep waiting for the MS sample and/or roll my own if I run out of things to work on before they release it. I really wish the MS/GSE team would reconsider their whole sample release policy. While I understand the red tape that can be involved when releasing things from a large organization like MS, with a brand new just-at-1.0 project like XNA/GSE, having so few samples to look at is pretty dreadful. You guys could probably save me 4 hours of slogging through the documentation by releasing a partial, non-fully-working couple of dozen line code sample that shows the gist. I'd much rather have something partial even if it is non-optimal or slightly buggy than nothing at all. Tag: Direct3D 10 HLSL grammar missing in April SDK Game Technologies: DirectX, XNA, XACT, etc.

    - Weird backface glitch I think that looks correct, unless I'm missing something. The DirectX Viewer comes with the DirectX SDK, and although the DirectX SDK isn't required to develop XNA applications, it has some useful tools and samples for the XNA developer.

    - How to run my XNA game on another computer Hello Jim, I had similar problems and id installed all the latest versions of the 3 requirements. Still didnt work but some one had posted a zipfile containing the following files. 07/02/2007 16:09 <DIR> . 07/02/2007 16:09 <DIR> .. 28/09/2006 16:05 2,414,360 d3dx9_31.dll 18/11/2006 17:23 700,416 Microsoft.Xna.Framework.dll 18/11/2006 17:24 94,208 Microsoft.Xna.Framework.Game.dll 28/09/2006 16:03 15,128 x3daudio1_1.dll 28/09/2006 16:05 237,848 xactengine2_4.dll 28/09/2006 16:04 68,888 xinput1_3.dll 18/11/2006 18:06 2,022,208 XnaNative1.dll once they were in the same folder as the xna exe everything worked. I think the d3dx9_31.dll was the "magic bullet" and it would appear to be native code i could put all the others bar it into a sub -folder and tell the runtime to search that folder with the config path. so it had to remain beside the exe or go into the system32 folder. as i said Im fairly sure id used the latest "at the time" releases of .net2, directx 9.oc, xna framework. Just so people know. Tag: Direct3D 10 HLSL grammar missing in April SDK Game Technologies: DirectX, XNA, XACT, etc.

    - Problem with "How To: Animate a Sprite" Tutorial This brings up a good question for the XNA team, is there any way you could make the source code for the samples available either as a download or at least a file-by-file source listing in the doc There have been a few instances where someone has followed the tutorials and received unexpected results and it's hard to track down the problem since there's no easy way to tell what was mistyped.

    - Help Please, kinda alot of questions in here Im daily constantly reminded that nobody makes makes Quake III Arena on their first attempt. Not even John Carmack. Well maybe John C. but he'd be the only one that could :) Programming games is not easy and add to that 3D graphics which only makes it alot harder. Gamedev.net reminds me every so often to take it one step at a time. You gotta crowl before you can walk. Im affraid you are going to have to crowl through the mud and learn it the hard way before jumping the fence. Remember there are many experienceses that needs to be learned before you become one with the force... Actually just hours ago I saw the light. I implemented a GameState mechanisme with a stack and an IGameState interface that all the different ScreenState classes implements. And even refactored an abstract base class in there to hold all the basic information like a reference to the graphics device and the GameStateManager object. Need. It works. Cant wait to get this architecture wrapped around a game. So you see. You have got to go thru these stages to become a good game programmer. Start by doing some 2D first. Do a tetris clone. Then a Mario clone. The when you got the hang of it start looking into 3D. Might even upload my GameStatePrototype to some hosting site. I am actually a little proud of the outcome.

    - Managed DirectX much slower than OpenGL The history of how to handle your render loop in Managed DirectX is a long and slippery slope - see http://www.thezbuffer.com/articles/185.aspx No matter what you think those numbers mean they only apply in a totally empty project. As soon as you do any work at all inside the render loop it will take several orders of magnitude longer than the slight increase you see from the improved versions. You will see less GC activity but it won't account for your discrepancy on frame rate. When i did the hexic demo for MS I switched in the Paint/Invalidate render loop instead of the interop based one - there was no measurable difference other than a few more GCs if you watched perfmon.

    - Humorous but somewhat serious question about XNA "People will make a clear decision as to whether they want that sort of product -- a kids toy -- or they want high-definition gaming and entertainment and all that it brings." Source: http://www.gamespot.com/pages/unions/read_article.php topic_id=25129507&union_id=5331 But yeah, I'm not really arguing here. I just don't see XNA's performance overtopping the Wii's graphics ability which is far below competative standards for today's games. Native DirectX has built Oblivion alone, which is more awe-inspiring. I still like XNA - it's a great tool for hobbyists, and they will probably never meet the day of XNA's limits so it's perfect for them, but it will still have to win me over for commercial development. And yes, far beyond XNA Racer. Good start though :) I'm willing to be swayed over to XNA though, but it may take a few more versions to get to that point.

    - Deplacement of sprite, round to int problem... I think that the problem may be that you want to track the cumulative time elapsed, rather than the cumulative function of those tiny changes in time. Based on your description, it sounds like you're expecting each call to Update to make some noticable change. Sometimes the difference in time between frames may be too small to notice in your object's movement. Try something like this: private double m_totalElapsed = 0; public void Update( double elapsed){ m_totalElapsed += elapsed; myPosition.Y = Math.Sin( m_totalElapsed ) * 5; } Where Update() is a member of your game object and elapsed is the number of seconds that have elapsed since the last time Update() was called.That way your animation will be smooth over time. Hope that helps. -- joe Tag: Direct3D 10 HLSL grammar missing in April SDK Game Technologies: DirectX, XNA, XACT, etc.

    - Character Jumping... Using physics principles. You need a Y location variable, a Y velocity, and a Y acceleration. Every frame/tick, your Y location is updated by adding the Y velocity, and your Y velocity is updated by adding the Y acceleration. float ypos,yvel, yacc; ypos = ypos + yvel ; yvel = yvel + yacc; then you set yacc to your gravitational constant (-9.8 ) and yvel to 0. When your user clicks the jump button, set yvel to some number (say 100) then on the next frame the character will move 100 units up, on the next it will move only 91.2 units up, and then so on until the variable reaches 0, at which point it goes into negative numbers and your character moves back down to the ground. You must set your yvel to 0 when ever there is ground under your character. Hope this helps. Tag: Direct3D 10 HLSL grammar missing in April SDK Game Technologies: DirectX, XNA, XACT, etc.

    - 360 Deployment Issues I hadn't tried that so gave it a go. No joy. Connection still just times out. Don't know what else to try. It's a Belkin router and the virtual server section only lets me add ports to 1 ip address. So say I add 1000 I can assign it to 192.168.2.8 (the xbox360) or 192.168.2.13 (my PC) but not both. I don't know if it's that or not but I'd have thought ping would work fine (and that still times out). Thanks!

    - Q on Terrains For the terrain texturing (brick path, worn grass/dirt, rock, etc), typically you'll use texture splatting. For the detail geometry, you'll either use generated detail geometry (grass, etc), or artist-placed detail geometry. For general approaches to terrain rendering, vterrain.org is a great place to start. Tag: Direct3D 10 HLSL grammar missing in April SDK Game Technologies: DirectX, XNA, XACT, etc.

    - Optimizing Multi-Rendering of the Same Model Yah, you pretty much just want to reduce the number of Draw calls you make to the GPU. It can process a lot of Vertices/Fragments in parallel, but every time you have to switch data (like a texture) you have to stop the process and go back and forth between the GPU/CPU/memory before the GPU can start churning numbers again. So yah, your method of splitting up the draw calls so you're drawing parts grouped by texture would work great.

    - How I get the index array from a model? I load a model from file into XNA and I want to store the data for modifying the vertex and adding some vertices and make some other transformations, like grouping all the small models in one single vertex buffer and index buffer and making a basic collision detector with walls. I have followed the issue and I found this topic http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=891302&SiteID=1 Ok, It wasn��t easy, but finally I can manage to get the vertex of the models. But when I try to get the data from the index buffer I get this error "You cannot call GetData on a resource that was created with ResourceUsage.WriteOnly." And the ResourceUsage property is readonly, (althought in the documentation says "gets or sets") and it seems that there is no way to change that. My code is something like this: Model mod = content.Load< Model >(resourceDirectory + assetName); ModelMesh mesh = mod.Meshes[0]; VertexPositionNormalTexture [] meshVerts; byte [] data = ( byte [])mesh.Tag; VertexPositionNormalTexture [] vertexBuffer = GetVertexBuffer( data ); int [] indices = new int [mesh.IndexBuffer.SizeInBytes/4]; mesh.IndexBuffer.GetData< int >(indices); <ERROR> Is there someone who has any idea how to get the index array from the model I would appreciate any help. please...

    - xna level/map editor It is possible to continue to use the Content Pipeline and load addition resources dynamically. You can read this thread for more details. It basically involves using MSBuild to package the resources up for your project. Mike36 gives the most details on how to accomplish this. I've done some preliminary tests with using MSBuild.exe (mine is located on C:\Windows\Microsoft.NET\Framework\v2.0.50727) and I'm able to do dynamic model loading at runtime. Here are some steps to try: 1. Do the steps outlined in Tutorial 1: Displaying a 3D Model On The Screen. 2. In LoadGraphicsContent, change myModel = content.Load< Model >( "Content\\Models\\p1_wedge" ); into myModel = content.Load< Model >( "Content\\Models\\MyModel" ); Note that you can replace "Content\\Models\\MyModel" with a string variable to simulate a name you got from somewhere. 3. Make a copy of the Content folder you created in the project in Step 1. Place this copy in a new project directory, Test, that you create. 4. Use the following sample project file and place it into the Test project directory: <Project DefaultTargets="Build" xmlns=" http://schemas.microsoft.com/developer/msbuild/2003 "> <PropertyGroup> <XnaFrameworkVersion>v1.0</XnaFrameworkVersion> <XnaPlatform>Windows</XnaPlatform> <XNAGlobalContentPipelineAssemblies>Microsoft.Xna.Framework.Content.Pipeline.EffectImporter.dll;Microsoft.Xna.Framework.Content.Pipel ine.FBXImporter.dll;Microsoft.Xna.Framework.Content.Pipeline.TextureImporter.dll;Microsoft.Xna.Framework.Content.Pipeline.XImporter.d ll</XNAGlobalContentPipelineAssemblies> <XNAProjectContentPipelineAssemblies> </XNAProjectContentPipelineAssemblies> </PropertyGroup> <ItemGroup> <Content Include="Content\Models\p1_wedge.fbx"> <XNAUseContentPipeline>true</XNAUseContentPipeline> <Importer>FbxImporter</Importer> <Processor>ModelProcessor</Processor> <Name>MyModel</Name> </Content> </ItemGroup> <ItemGroup> <Content Include="Content\Textures\wedge_p1_diff_v1.tga"> <XNAUseContentPipeline>true</XNAUseContentPipeline> <Importer>TextureImporter</Importer> <Processor>SpriteTextureProcessor</Processor> <Name>MyTexture</Name> </Content> </ItemGroup> <Import Project="$(MSBuildBinPath)\Microsoft.CSharp.targets" /> <Import Project="$(MSBuildExtensionsPath)\Microsoft\XNA\Game Studio Express\v1.0\Microsoft.Xna.ContentPipeline.targets" /> <Import Project="$(MSBuildExtensionsPath)\Microsoft\XNA\Game Studio Express\v1.0\Microsoft.Xna.Common.targets" /> </Project> 5. Open a Command window and navigate to your directory with MSBuild.exe (mine is located on C:\Windows\Microsoft.NET\Framework\v2.0.50727). 6. Type "MSBuild <project directory>Test.csproj" without the quotes, where <project directory> is the place you put your files. Example: MSBuild C:\Projects\Test\Test.csproj. You'll get a build error, but your content will be compiled. 7. Copy the files from your Test directory's Bin\Debug\Content\Models and Bin\Debug\Content\Textures directories to the corresponding project directories you created in Step 1. 8. Run your project in Step 1 to see the model! Since MSBuild.exe is built-into the .NET Framework, an editor can generate a project file similar to the one in step 4 above, compile the models specified by the user, and then copy the results to a game's content directory. A game written to dynamically load content files would then have models and textures in the proper format. Not a bad way to go! And you can read this thread for getting XNA to work with Forms. It's a fairly straightforward process with no API calls. Hope that helps answers your questions. Good luck with your level editor!

Sorry about posting a new thread here, but I'm hoping I can sneak in a quick one while no one is looking.

Any word on whether the grammar will be included in the next SDK I see a reference to it in the HLSL appendix, but the grammar itself seems to have fallen off the bottom of the page.

On a side note, any chance of having a peek at the specification I see that it's available to IHVs, but what about the rest of us I think that it might provide a very useful reference for us mortals, too.
