• Rajith New 2D Xmas Themed Game

  I have written my first ever XNA game, it is a Christmas themed 2D game. It is called Elves Revenge, and screenshots and gameplay demo are available at http://www.errolian.com Full details of the game and the downloads (game, plus source code) are at http://www.errolian.com/2006/11/22/3d-buzz-xmas-game-coding-contest-elves-revenge/ Remember that you should realy make posts like this comments if you are not asking a question. There was nothing wrong with the post except that it was marked as a question... If you make the post a question and it goes un answered it goes against the stats for the forums, also (From memory here) the answered questions are ranked higher in the search for the f ...Show All

• Muhammad Khalid Any Plans for Support for VS 2005?

  Does anyone know if there are plans to support VS 2005 at some point There are a number of missing features in VC# Express which I have come to rely on. Most notably, Macros. My productivity is hindered in Express. I would really like to be able to use VS 2005. At the moment, I am using a custom pipeline content generator and the XNA assemblies under VS 2005. Which is a complete hack, but it does work (on Windows). Basically, it means I have to eventually recreate the projects in XGS in order to make them work on the 360. So does anyone know if there will ever be real support for VS 2005 I agree 100% with the decision to support the Express editions, but it would be nice for me (a hobbyist game developer but pro web/win developer ...Show All

• Mosesm Converting to and from a view matrix.

  Hello everybody. I am trying to convert back and forth between a view matrix (created with matrix. CreateLookAt ) and a position, rotation and scale. I believe I have figured out how to convert into a view matrix from a position, rotation and scale like this: Matrix sc = Matrix.CreateScale(_scale); Matrix rot = Matrix.CreateRotationX(_rotation.X) * Matrix.CreateRotationY(_rotation.Y) * Matrix.CreateRotationZ(_rotation.Z); Matrix trans = Matrix.CreateTranslation(_position); Matrix transformation = sc * rot * trans; Vector3 orig = Vector3.Transform(Vector3.Zero, transformation); Vector3 target = Vector3.Transform(Vector3.Forward, transformation); Vector3 upPoint = Vector3.Transform(Vector3.Up, transformation); v ...Show All

• davidgsteadman Can I get the vertex data after rendered

  Can I get the vertex data after rendered, i.e. I want to transform a scene to diplay with a special way not the perspective projection, is that possible Ideally, you shouldn't need to read vertex data back from the GPU. Since your goal is for display purposes, then just do your custom calculations in the shaders. If you really think you need to read transformed vertices from D3D, then look at the ProcessVertices() method of Device/IDirect3DDevice9, but you won't get different calculations when using this method. It's only that it does the calculations on the CPU instead of the GPU, so your CPU code can read the values... Vertex processing is handled by the vertex shader (as the name implies).

• cheesetarmac Help on writing text on the screen?

  I'm well on my way to finishing my first mini game called planet defender. What I need now is a way to display the score the player has on the screen.

• Forch Space Wars no weapon 4

  When I play The Space Wars starter set, I can play it without problems, till i try to fire the $4,000 weapon. then it gives an error on the modelMesh.Draw(); line How would I get it to work How would I do that You'd need to fix the source model that is displayed for that weapon. An easy hack would be just to copy one of the other weapon graphics over the one that is causing the problem. It gives the error: Invalid function call This sounds like a bug we recently fixed in our internal builds: the model for that weapon was missing texture coordinates. It'll be sorted for the final release. ...Show All

• orent Primitives appear grey (black when lighting is enabled)

  I posted this in the Framework forum (seemed to make more sense there), but there seem to be more people active in this one, so maybe worth posting a link: http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=692742&SiteID=1 If I turn lighting on, my triangles are black. If I turn it on, they're grey. They're supposed to be read. Full source linked from that post :) Awesome, thanks :) The reason I wanted to avoid an external .fx file is because I completely don't understand them. But hey, I'll just use the documented one for now, and learn them another time! :D I think the problem has something to do with the BasicEffect, though I'm not sure where. I tri ...Show All

• Memom Designing C# & XNA games

  Hi I'm currently learning C# from a couple of books with the sole aim of being able to use XNA.  I have just a couple of questions: At the moment I focusing on console (DOS like),OOPs, and so on.  With XNA, is there any point in learning Windows Forms programming   Also, I found that understanding & following game code is one thing but being able to design a game (or any program) is another thing entirely.  It's hard to code without some higher level plan or visual aid.  Are there any techniques or affordable software available that game designers use in the design process.  I've heard of things which might be applicable, such as :- Psuedocode, UML process diagrams, he ...Show All

• uanmi What does creators club include right now?

  I'm a little puzzled about what the creators club actually includes, I've checked the FAQs and can't really find an answer. I have however managed to find the following: "The XNA Creators Club is available on Xbox LiveR Marketplace for $49 (U.S.) for a four-month subscription, or $99 (U.S.) for an annual subscription. Both subscriptions provide aspiring game developers with access to thousands of game assets from Microsoft and key partners such as Turbo Squid Inc., as well as white papers, specialized starter kits, samples and technical product support to help turn Your World, Your Game into a reality." I signed up for a year because it sounds like quite a good package, however there seems to be no information provided on ...Show All

• amendez How to detect version of D3DX installed?

  With the newer versions of DirectX there are several different D3DX dlls that exist. Just checking for DirectX version 9.0c is not sufficent as that version contains several revisions of the D3DX dlls. If a game ships with the April release the earlier versions of DirectX 9.0c will not work. How can the exact installed version be determined If you go to the Microsoft WWW page where you can find the current SDK to download, you'll find a link for the " DirectX End-User Runtime Web Installer ". This is the link is where you want to direct users to. Ok, so the core runtime hasn't changed, so its version doesn't change. Sure, that makes sense. But Direct3D, wh ...Show All

• KeithGWilliams Sound Pack

  Max Damage Studios is now making its release of its Missile Command XNA remake public. You can go directly to our downloads page to grab it. This project was mostly a proof of concept written in a very short, around 10 hours, amount of development time. We made use of a few of the DirectX SDK Tools such as XAct to get the final result. All audio work was done in our studio. There are only 11 levels in version 1.0 currently, but perhaps someday we shall extend that and produce another version. But we are moving on to our next project for now. Never mind. I didn't notice I'd run out of missles. :) Pretty nice. The fire button stopped working on the 3rd level and 4th however, right as I got a Max Damage. I can't edit the ab ...Show All

• SharePointing Animation Transform Question

  Hey, in XNA I am doing animation by  finding a bone's final transform for a given animation frame. I do this by first finding the transform of the bone for that frame through interpolation or direct keyframe data, then finding the absolute transform of the bone for that frame, and finally multliplying it with the matrix that transforms a vertex to the local space of the bone. Since the bind pose in XNA is stored in the bones, unlike in directx, I get it by multiplying the absolute mesh transform by the inverse absolute bone transform. This seems to work fine for all .X files, but for .FBX files, it seems to not work sometimes. Is this algorithm not compatible with .FBX files, or is this probably a bug in my code/invalid fbx file ...Show All

• VickyP Preserve alphas in rendertargets?

  Let's say I first clear the screen with the color black, then draw an interlaced PNG and store this in a RenderTarget. After that I apply a PixelShader to the RenderTarget and store that in another RenderTarget. Clear the screen with the color white or draw a background image. If I now try to draw the last RenderTarget with the effect applied, the background doesn't show because the RenderTarget hasn't the alpha channel the interlaced PNG has. Is my English understandable How do pass in the alpha channel from the PNG to the RenderTarget If this is possible how do you do it with multiple PNG's Alfons Bit of a newbie myself but this may be what your looking for All the defined colors ie black skyblue et ...Show All

• Bill_C Bypassing Categories

  Is there a way of bypassing the Categories volume when playing back sounds through the auditioning server I'm trying to set individual sound levels and I'd like to be able to bypass the category's level setting when doing this. Alex The auditioning server takes into account all the volume controls, so no, there isn't a way to bypass the category's volume levell when auditioning the sounds. Best I could suggest would be to temporarily set the category volume to 0dB, then set it back when you're done w/ your changes. -Brian ...Show All
