    - .. I did it Part2 Loading FBX file Vb.net TRIDEX ..... I'm really curious why using XNA with VB.NET is such a high concern. I use VB.NET every day at my job. I love it and highly recommend it. But I've had no issues coming home at night and working with XNA in C#. The languages are so similar at this point that it's not even worth the effort to try and convert things. So while I applaud you championing VB.NET, and I personally think it's a great language and love how readable it is, I wince every time I see you post about using XNA with VB.NET. I just feel you're encouraging people down the wrong path when really the can make things so much easier on themselves if they just bite the bullet and stop being scared of C#. Knowing how to use both languages just increases your overall skill level and worth and really just makes things easier all around. Then you have the advantage of using XNA how it was designed, getting the full benefit from all available tutorials and sample code. So in my opinion, your greatest service to the community would be to stop pointing out how they could use XNA with VB and instead show people how easy C# is to pick up and use if you already can program with VB.NET. You'd be doing developers in the community a favor by removing their fear that using one or the other language is difficulty and newcomers in the community a favor by guaranteeing they have access to the most tutorials. I realize you might not agree with this and you seem incredibly passionate about VB, but I really hope you stop and think about this a little more. I apologize for going on such a long discourse here, but I guess I've just been wanting to say this for a while now. Hopefully you understand this is just an a opinion of someone who is concerned about what is best for the community and new game developers.

    - Packaging assets The short answer is yes, you will be able to use your own packaging system. The long answer is that it will take a bit of work and knowledge of MSBuild. To answer your other question, the Storage API is restricted on Xbox 360, but not in a way that will affect what you want to do. Basically, the restriction is that you are prevented from being able to see files that aren't part of your game (so you can't go off and modify your Gears of War data files, for example). You can, however, see all the files that are deployed as part of your title. The tricky part will be building your project for the 360. The Content Pipeline build task defaults to putting its output in the project output directory, and everything in the output directory is considered "part of the game" and will be deployed to the Xbox 360 before you debug/play it. You don't want all these files AND the package file to be deployed, so you'll have to do some work in the build system to avoid duplication. If you want to use the Content Pipeline, it's going to build your content and generate a bunch of files from them. Those are the files you want in your package, so you'll probably want to create another MSBuild task that takes that output and builds your package. To do that, change the output directory for the Content Pipeline task so that it goes into a new intermediate location (by editing either the project file directly). Then have your new task use that directory as input, and generate the package into the project's final output. The project will then automatically deploy your package file along with your game when you connect to your Xbox 360. In your code, you'll need to write a class that opens your package file and reads the contents into Stream objects. The content manager has an overload to load assets from streams, which is what you'll have to use instead of the overload that takes a file path. That way, you can load directly from your package. I hope this points you in the right direction. Unfortunately, explaining all of it would take more time than I have right now. --Stephen Tag: XNA Game Studio Express xna and xbox 360 Game Technologies: DirectX, XNA, XACT, etc.

    - What is MultiSampleQuality This parameter is deliberately left vague in the DX documentation, because it is mostly up to the driver to define what it means. It is needed because even within a fixed number of samples, there can be different ways of implementing the details. For instance with 2x AA, do you just double the width of the backbuffer, or do you rotate the sample kernel When downsizing, do you just average two samples for each output pixel, or perform some more sophisticated (and hence expensive) filter to get better results For instance in the GeForce3/4 NVidia implemented Quincunx filtering, which renders with a rotated 2x AA kernel but then samples five surrounding values to compute each output pixel. The API needs a way to control which option you want, but it doesn't really know what options the driver may have implemented, so MultiSampleQuality gives a way for the driver to report "ok, I support 3 different ways of doing 2x AA", and then the game can say "right, I want the second of those". Of course, it's not easy to make a sensible choice here because you don't really know what the different options represent (unless you happen to recognise the card) so most often this value should be left alone. Plus, even if you do try to specify it a lot of drivers do crazy stuff like overriding what the game requests based on control panel settings made by the user, at which point the whole thing becomes irrelevant in any case!

    - Vertex stride in stream 0 is less than in the declaration Thank you for the reply, but I'm still getting the same error. Let me re-iterate what I'm trying to do and the code: I am given a user-defined vertex buffer, a user-defined stride in the buffer and a user-defined vertex shader. Using these, I want to get the output vertex buffer. Here are the steps that I take: 1. CreateVertexBuffer for the input vertex buffer. This time I used an FVF of 0. According to me, giving an FVF of 0 should take care of this error. Earlier I was setting the FVF to DIFFUSE | XYZ, which was incorrect. Ideally, I want it NOT to use the FVF at all and use my own user-defined stride. 2. SetStreamSource with this newly created Vertex buffer in step 1 and I set the stride to the user-defined stride. 3. Create an output vertex buffer and call ProcessVertices(). Once again, I get the same error, i.e. Vertex stride in stream 0 is less than in the declaration. In the light of the above, I'd appreciate if someone could tell me: 1. What exactly is it comparing the stride in stream 0 to I know that the stride in stream 0 is user-defined and exactly what I want it to be. I guess I need to fix the other value it is comparing the stride to. I thought giving the FVF to 0 when creating the vertex buffer will negate that stride and only use the one I give in setstreamsource. 2. How to fix the error.

    - directx10 performance enhancements for directx9 games. i see, i thought directx10 would be backward compatibe for older api and hence employ those enhancements. i thought that dx10 would be able to run the dx9 game it's just that the dv9 game would be without feratures such as sm4.0. but now i understand. well looks like it's a new CPU for me then to, actully complement my x1900xtx. i shall just have to wait until crysis for a new card.

    - Camera track bend Thanks for your answer Cale. The camera is actually automatic; the user has no control over it. Currently, I am using a "percentage from distance" to determin the speed of the camera, which acts as a kind of gravity - this works really well. Imagine there is a room with 2 adjacent walls; and 2 points of interest are in the corner of the room on each wall... Simply moving from 1 to the other really looks quite boring as all you get to see is the corner of the room. What I want to do is have the camera pull away from the wall, and then zoom back in again.

    - Rotation help I think I understand what your after but not quite sure, I distilled my tranformations into one class for the sake of clarity, I havent had the time to optimise it yet and not even fully sure if its without problems, however I think it does what you need it to do, I am just going to paste the entire class so you can have a look at how I am dealing with Quaternion based rotations, I am by no means an expert and any advice on this is much appreciated.

    - Single letter prefix before a variable This is a touchy topic, I suggest you read the .NET Framework Class Design guidelines on MSDN, and then do whatever you feel like. This is one of those religious-debate style topics that has no perfect answer. Here's a link: http://g.msn.com/9SE/1 http://msdn2.microsoft.com/en-us/library/ms229042.aspx&&DI=6066&IG=6d6851dbf763472d88f868eeb9905420&POS=4&CM=WPU&CE=4&CS=AWP&SR=4 My answer, for what it's worth, is: However you name your variables, design your classes, and architect your solutions, be consistant with yourself.

    - Custom Content Manager - Generics Question If you're not using switch you can use the is keyword. if (asset is Texture2D) { //.... } You could also use a dictionary that is keyed by type to store your type "finders" and then look up a finder object. This helps because you don't have to change your source code every time you add a new asset type. // new types interface IAssetFinder {...}; interface IAssetFinder<T> : IAssetFinder {...}; // in setup Dictionary<Type, IAssetFinder> _assetFinders; _assetFinders[typeof(Texture2D)] = new Texture2DFinder(); // add other asset types... // in Get<T>() IAssetFinder<T> finder = _assetFinders[typeof(T)] as IAssetFinder<T>; asset = finder.Find(filePath); Also, assuming you don't mind using pre-built assets (.xnb), it's quite easy to derive a new content manager that loads files from other locations such as network shares, from web servers, inside zip files, etc. Just derive from ContentManager and override ContentManager.OpenStream().

    - Setting Global Matrices for Models As Fluxtah mentions you can use EffectPool to share EffectParameters between instances of an Effect. Also, depending on how you are organising your effects, you don't need to set parameters every frame if the previous value is still valid - for example if you have an effect instance for every mesh then each instance has its own params (apart from any shared ones as mentioned) so you don't need to re-set them with the same value. If instead you were sharing instances of effects between many meshes then you would set those params that are the same for all meshes once and then change the mesh specific params (such as the world matrix) for each mesh. By the way, this is not so much an OpenGL vs XNA issue as a fixed-function pipeline vs programmable pipeline issue. Cheers, Leaf.

    - Another Alpha Blend Question in Managed DirectX 9 I am trying to draw a textured transparent square. Here is the drawing code: CustomVertex.PositionColoredTextured[] verts = new CustomVertex.PositionColoredTextured[4]; verts[0] = new CustomVertex.PositionColoredTextured(-10.0f, 10.0f, 0, Color.FromArgb(128, 255, 255, 255).ToArgb(), 0, 0); verts[1] = new CustomVertex.PositionColoredTextured(-10.0f, -10.0f, 0, Color.FromArgb(128, 255, 255, 255).ToArgb(), 0, 1); verts[2] = new CustomVertex.PositionColoredTextured(10.0f, 10.0f, 0, Color.FromArgb(128, 255, 255, 255).ToArgb(), 1, 0); verts[3] = new CustomVertex.PositionColoredTextured(10.0f, -10.0f, 0, Color.FromArgb(128, 255, 255, 255).ToArgb(), 1, 1); device.SetTexture(0, grassTexture); device.VertexFormat = CustomVertex.PositionColoredTextured.Format; device.DrawUserPrimitives(PrimitiveType.TriangleStrip, 2, verts); And I have the following to enable alpha blending: device.RenderState.SourceBlend = Blend.SourceAlpha; device.RenderState.DestinationBlend = Blend.InvSourceAlpha; device.RenderState.AlphaBlendEnable = true; It seems like this should work from the tutorials I've seen and since I'm setting the alpha of the color for each vertex to 128, but unfortunately this draws the square opaque. I know that alpha blending is working because If I load a texture with an alpha channel it is transparent where it's supposed to be, and if I use CustomVertex.PositionColored it also works fine. I read on the MSDN that Renderstate.DiffuseMaterialSource might help, but I've tried all three settings and this did not help... so I must be doing something wrong... again...

    - C# - Managed DirectX - Secondary Monitor Hi, Thanks for your reply. The problem I have isn't so much with debugging, because it does run on the seperate monitors. But, if for example with code similar to that you have suggested, I do enter a breakpoint in Visual Studio...even though shown on the seperate adapter it still minimizes when running in fullscreen mode. I can have the DX device initialised to run in window mode (which appears fullscreen, with removed borders and controlbox)...but it performs too slow. When running fullscreen it performs fine, but the end-user cannot use Microsoft Access (or any other program) whilst the DX device is shown on the second device (in fullscreen mode). Somehow I need to get my program to run fullscreen, whilst allowing the user to interact with Windows on the primary monitor. The program I am creating is not directly interactive in anyway, and never actually requires keyboard or mouse focus. It acts as an output for and Access database, and automatically recognises when changes have been made. This part works fine. There is something in the DirectX SDK which is forcing itself to minimize when something happens outside. The same effect happens in commercial games, so if you were to have a game running on one monitor and outlook on another. Clicking on an email in outlook would cause the game to minimize. Usually this is understanbable, but in my program I need to allow the user to work on device 0 whilst my program does its own thing on device 1.

hello for all, i have a little question here, i'm making a game for windows with the xna framework 1.0 but in the future i will want to port it to xbox 360, with the xna framework i will can sell the game or i need another framework or sdk to make a xbox 360 comercial game

i 'm a new indie game programming and i need help with this topic, i want to know if there will be another version of the xna or another sdk to make comercial xbox 360 games and the cost of this software.

Thank you in advance..

Re: XNA Game Studio Express xna and xbox 360

Peter D.

To sell the game on the 360, you will need to have the professional version of XNA and be certified by Microsoft. It is not clear how you go about doing this as an indie at present.

XNA express will only allow you to sell windows based games. I am using it to learn the 360 so that I can produce some games that will work well on colsole and PC.
