    - Problem with content .x files on build. I have a small xna application working. I can load an .X file, render multiple of them -great. Now adding another .X file (created identically, added the same way -[existing file, content] It throws up errors on the build. Is there some kind of caching taking place, or a pre-build action I should be doing Searching for the .x model name it shows up in both the ContentPipeline.xml file WITH TWO ENTRIES.

    - Ignoring mouse events outside of window / while app is not focused I see that the mouse / keyboard state reflects the state of the mouse / keyboard even when the application is not focused. In a way, this makes perfect sense. What I'd like to know is what is a good way to make sure my application does not process these events when the app isn't focused or a click happens outside of the app window. Thanks!

Now, the sceen shows a rotated mesh. But i want the screen to show as if the mesh hasnt rotated at all. Meaning i want the camera to rotate with the mesh. Im using MDX and C#.

    - XNA sprite behavior -- weird side effect Hello, I'm new to XNA as well as DirectX and am experiencing some weird side effects when drawing a sprite that I can't account for. I have a 3D ship that I can fly around using the Xbox360 controller (completed the XNA tutorials 1-3) and decided to see if I could implement pausing. Well, i got everything working how I want it and even made a 2d sprite that loads a texture asset and draws it to the screen when the player pauses (just a blue rectangle with the word "Paused..." written on it). That works great too, except by drawing the sprite to the screen my 3d model suddenly becomes semi-transparent! Even when the sprite is no longer being drawn the model remains semi-transparent until I restart the game. I am developing in XNA Game Studio Express and deploying onto my Xbox360. I am confused by this side-effect of drawing the sprite. The 3d model references a .tga for it's texture but it is completely separate from my .bmp texture (which has been added through the content pipeline). Here's the code that causes the effect (by commenting it out I no longer see the Pause sprite but also no longer get semi-transparency on the model): spriteBatch.Begin( SpriteBlendMode .None); spriteBatch.Draw(pauseTexture, new Rectangle (graphics.GraphicsDevice.Viewport.Width/2 - pauseTexture.Width/2, graphics.GraphicsDevice.Viewport.Height/2 - pauseTexture.Height/2, pauseTexture.Width, pauseTexture.Height), Color .White); spriteBatch.End(); At first I didn't use a SpriteBlendMode but thought maybe by explicitly using SpriteBlendMode.None I would avoid any possible transparency confusion, but it has no effect.

    - XNA Demos Released Hi All, I've just started a new series of XNA demos on my website. So far I have 3 demos: XNA Per-Pixel Lighting Demo, XNA Normal Mapping Demo, and XNA Parallax Normal Mapping Demo. I haven't included any pre built executables with the demos, so you'll have to build them yourself from the source provided with each demo. The demos target the Windows platform, but should run with little or no modifications for the Xbox 360. I chose to only target Windows to reduce the complexity of the source code. The per-pixel lighting demo implements per-pixel Blinn-Phong lighting (including specular lighting). The normal mapping demo implements tangent-space normal mapping. The demo also shows you how to calculate the tangent space basis vectors (tangent, bitangent (aka binormal), and normal vectors). Finally the parallax normal mapping demo extends the normal mapping demo by adding parallax mapping with offset limiting. All demos include an effect (.fx) file with techniques for directional, point, and spotlight lighting. Hopefully the code is clean and clear enough for it to be of some use.

    - I want to use a simple fx shader on a simple loaded model What I want to do seems very simple to me. I want to do this - Load a 3D model using ContentManager.Load<Model>(...) Load a shader Effect from a .fx file using ContentManager.Load<Effect>(...) Render the 3D model using the shader from .fx file. Can anyone give an example of this that is as straigh forward as humanly possible It does not seem like this should be a difficult thing to do, but I have no idea since I've never used shaders. Also, if anyone has a simple .fx file I can use to test my code, that would be great! I'd love to give my Buttermilk game / GUI engine the power of shaders! Thank you for reading!

    - Build for Xbox 360 and Windows in one project I have created a Visual Studio project template that can be built for either Xbox 360 or Windows, by selecting the correct platform in the VS IDE. There's nothing particularly clever about this, it just uses some of the conditional abilities of MSBuild projects to merge the properties of an Xbox 360 XNA project with a Windows XNA project. There's a slight problem though - the VS Express C# IDE has, by default, disabled the build configuration and platform settings to present a simpler interface to beginners. In order to use this project template you need to re-enable these features and should probably have a reasonable understanding of what they do. This could be the reason that the XNA devs have mentioned that building for both platforms in one project is not currently supported. But, if you do understand the build configurations in VS and think this might be useful then you can find out a little more and download the project template here . Cheers, Leaf.

    - RenderTarget2D rendered with garbage all over it Hi I've got a 2D project where the world is rendered to a 1024x1024 RenderTarget2D texture, then that texture is drawn to the backbuffer. It works fine on my laptop. On my desktop, however, the RenderTarget2D texture is drawn with an overlay of garbage consisting partly of a frame of a DVD I was watching on the other display. I'm clearing the RenderTarget2D texture properly, and everything is drawn properly, but when this texture is drawn to the backbuffer it receives a nicely alpha blended amount of garbage that covers the entire texture. So I can see everything rendered perfectly on the RenderTarget2D texture, it's just covered with translucent garbage. Sorry, I can't get any shots now. When I get home from work I'll get right on that, assuming I haven't got a solution yet. Is this a dual display thing or a graphics card thing or a bad programming practice thing The desktop has two displays and a GeForce 6600GT; the laptop has one display and an ATI Mobility 9600. Thanks, I appreciate it. Tag: XNA Game Studio Express silly question Game Technologies: DirectX, XNA, XACT, etc.

    - SpaceWar with a PC controller? Hello, I was experimenting the SpaceWar application, but it seems to expect a xbox360 controller instead of a broad PC controller since... well, I'm running it on a PC. Do you know anything about that I should be able to use it. I have a team that wants to use XNA for the PC platform - we could hardly care about the xbox360 at the moment. Forcing our players to have a xbox360 controller when they already have a fully capable controller does not make any sense. Did XNA leave out DirectInput or something I'd hate to drop back into MDX just because of this necessity. If MS has no answer for this, may I suggest that DirectInput should be included in XNA when the program detects its running on a PC Average Joe may not want to play the game if he can't use his chosen controller. Would I just have to include MDX's DirectInput.dll, and how can I assume there will be future support if it's not being updated I need something to work with for a broad set of controllers. Thanks for the thoughts in advanced. I like XNA, but I hope we can work with it. Tag: XNA Game Studio Express silly question Game Technologies: DirectX, XNA, XACT, etc.

    - loading large image using DirectX Hi all. First of all, I'm new to DirectX. I'm trying to load an image into a PictureBox component (C#) using DirectX. The problem is that I'm working with large pictures (for ex. 4021x3123) and can't use the Windows GDI, because the picture takes a lot of memory and it flickers when I move the scrollbars. That's why I was thinking of using DirectX. I've linked the DirectX Device with the PictureBox: Device device = new Device(0, DeviceType.Hardware, pictureBox1, CreateFlags.SoftwareVertexProcessing, presentParams); The problem is that I don't know how to load the image as a backgroud image using DirectX (i need to do some drawing on it after it loads). Is there a way to load it and prevent the flickering when i move the PictureBox's scrollbars Thanks. Tag: XNA Game Studio Express silly question Game Technologies: DirectX, XNA, XACT, etc.

    - Material vs Shader Welcome to another one of my newb questions! Can somebody explain the difference between a material and a shader My own ideas would probably be: - A Material defines the texture and lighting properties of a surface, and maybe even the sound properties of a surface. Visual qualities of a material can be described with shader(s) ! Anyway, if someone could give me some ideas here as I find the two terms quite conflicting, but its probably because of my limited understanding! cheers :) The reason I ask is I was thinking about making a Material class that maybe describes texture, lighting properties and sound of certain geometry. edit: by the way I have checked out the definition of a material in the directx documentation but it only describes a material as something that has lighting properties, surely a material can go beyond this definition Maybe material is something that was preshader :) confused...

    - Nvidia Vista Drivers Hello, I'm seeing a problem with the latest NVidia drivers on Vista (version 97.46 realeased on 5th Jan 2007), and I was wondering if anyone else is experiencing similar problems. The display card is an NVidia GeForce 6800 LE, but I don't think its specific to that display card. The problem I'm seeing is that DrawIndexedPrimitive() doesn't seem to draw anything if the BaseVertexIndex argument in DIP is larger the MaxVertexIndex caps value. The return value from DIP is OK, but it doesn't draw anything. I'm drawing representations of oil reservoirs made up of a large number of quads. The whole reservoir goes in a single vertex buffer which can often exceed 100MB in size. I am using an index buffer containing around 3000 indices. The contents of the index buffer are kept the same and the vertex buffer is drawn by increasing the the value of BaseVertexIndex at each DIP call. If further clarification is needed I can provide a code snippet. I've also written a very short test program to investigate this and I'm seeing the same effect. This approach of offsetting BaseVertexIndex to draw large vertex buffers has been working for us with no problems for several years now on XP on a range of cards, and we've had no problems drawing vertex buffers up to 200MB in size. I know this problem should best be addressed to NVidia but it seems to a little difficult to get technical answers of this kind answered directly by NVidia. On a related note, we'd like to use the newer cards with 512MB of memory to draw vertex buffers up to 512MB in size, but the maximum vertex buffer you can allocate seems to be around 256MB. Does anyone have any experience of this Thanks for any help, Robert Tag: XNA Game Studio Express silly question Game Technologies: DirectX, XNA, XACT, etc.
