    - Selling Games on Xbox Live Arcade Well first you need to make the game and talk to Microsoft about developing it for Xbox live arcade. You will also need to buy XNA pro next year so your game can be sold. I have made the common mastake of thinking about bring the game to XBL arcade etc etc and not actualy developing the game. Make working on your project your main priority. As you are useing XNA it wont cost you anything to develop it. Tag: XNA Game Studio Express Invert screen Game Technologies: DirectX, XNA, XACT, etc.

    - Embedded resources, Xbox 360, and the ContentPipeline. If I'm understanding correctly, you want to distribute an assembly, and nothing else I think that's how resx files work. As far as I know, a .resx file is compiled into the final assembly, which sounds like it will work perfectly for what you want. Put your default resources through the content pipeline in the normal way, and then create a .resx file in your project. Add the compiled .xnb files to the resx. Change the ContentManager to a ResourceContentManager, and you should be good to go. There's a bit of trickiness around how to create a ResourceManager for the ResourceContentManager, but I can't remember off the top of my head how that works. I think it wants an assembly or something I remember the call System.Assembly.GetExecutingAssembly being useful, but again I don't have the docs in front of me. Hopefully someone else will chime in with more details. Tag: XNA Game Studio Express Invert screen Game Technologies: DirectX, XNA, XACT, etc.

    - Problems with depth-Buffer Z values are not stored in the depth buffer with a linear function. I think it is a 1/Z like function. Anyway, it means that Z precision (the distance in meter between two Z values) is not the same near the camera or far from the camera. That is why you're experimenting that flickering. Also probably, if you move a bit more far, the rendering might flicker again. A way to correct this is to modify near and far values. Indeed, Z precision depends on Zfar / Znear ratio (see projection matrix for more details). I'm usualy try to keep this ratio around 1000, but it really depends on your assets.

    - Direct3D 9 -> Strange problem with vertical blank This is because Present returns as soon as the persent operation can be queued up, not when the vertical refresh actually occurs. The frames are queued up in the swap chain, and don't actually hit the screen until the vertical blanking period. DirectX will buffer up to three frames in advance, which helps to keep a stable frame rate despite variations of rendering time per frame, even allowing the occasional frame to take in excess of one refresh period without missing a frame. You numbers are indictive of this behavior. It took the first five frames 52-55 ms to render, during which time two vertical refreshes could have occured. After that your frame rate was locked by the refresh, as no more frames could be buffered. Tag: XNA Game Studio Express Invert screen Game Technologies: DirectX, XNA, XACT, etc.

    - Mesh Alpha chennal problem? Well, I think you’re talking about the transparency issues in the borders of the Chinese (sorry if it’s not chinese) characters. Aren’t you That’s a common problem with using alpha blending. As I see in your picture, you are using Alpha Testing to discard the parts of the texture you don’t want to render. That one is a binary operation, in which pixels are accepted or rejected, basing on a comparing function (>, <, etc). That’s fine and works flawlessly, but you are also using alpha blending to make the borders of the texture smoothly disappear with an alpha gradient. Arent you Whe you use alpha blending, you have to deal with the drawing order, because the blend operation performs a mix up of the color of the pixels that it’s going to render with the previously stored in the frame buffer. That’s why the rendering order matters. To workaround the problem, you can do two things: 1.- Don’t use alpha blending (obviously), only alpha testing, which will produce harder borders. You can improve the result using higher resolution textures. 2.- Ensure that render first every object without transparencies (alpha blending). Then render alpha blended objects, from back to front (first the ones that are farther from the camera). This implies using a sort function based on the distance to the camera. Hope this helps.

    - fx include not found - December SDK change I've noticed this as well, I'd be interested to hear from MS on whether it's a bug or feature, too. In the meantime, an alternative to calling SetCurrentDirectory is to change the #include to use the relative path, e.g. #include "subdirectory/include.fxh" Interestingly the D3D10 version of this function still seems to work in the old way. For the moment, I'm using the flag to use the legacy D3DX DLL on D3D9 to avoid having to change code or shaders in existing projects.

    - Building XACT project has failed error when building Spacewar Tutorial in documentation got some bug...maybe there's a problem: when loading settings, wave bank, and save bank...that's not really true that you should give same name as project and different extension. From my experience...(hour to solve this one). project will build into and create names it have in properties(default for audioEngine is sound, not your project's name) To make it clear - do everything as in tutorial, do not change anything in properties in Xact:...and change...this one: audioEngine = new AudioEngine("Content\\Audio\\MyGameAudio.xgs"); waveBank = new WaveBank(audioEngine, "Content\\Audio\\Wave Bank.xwb"); soundBank = new SoundBank(audioEngine, "Content\\Audio\\Sound Bank.xsb"); to this one: audioEngine = new AudioEngine("Content\\Audio\\sound.xgs"); waveBank = new WaveBank(audioEngine, "Content\\Audio\\Wave Bank.xwb"); soundBank = new SoundBank(audioEngine, "Content\\Audio\\Sound Bank.xsb"); EDIT: OH...my gosh...I wrote all this...but you were talking about Spacewar starter kit...sh.t.

    - Is it realistic to create one's own engine? I created a game engine that does alot of things with XNA Beta 1. It can do fonts, had a mesh class, a user interface (2D Buttons, was working on 3D Buttons), support for cursors, and tons of other stuff. But in all it still isn't half as good as the TorqueX engine. I also have that Do-It-Yourself impluse in me but I've noticed that it is much harder than I atticipated. First of I would recommend you to program lots of games in C# (I am different though in the sense that almost none of my games are ever finished but I still tackle big problems in each of them and succeed, therefore giving me the experiance). 3D, to me, is like the ultimate frontier. I can do 2D but for 3D I would need alot more math and creative thinking skills to be able to even attempt. So in conclusion to make an engine you need experiance, probably some sort of team, and alot of patience. I soon will probably just purcase an engine like TorqueX because it isn't worth trying to make an engine and spend 1 year or 2 when you can just buy one. But still my engine is very helpful because I still use it for alot of things (AnimatedSprite class, Tileset class, Mouse class, and Keyboard class, these are the most important). Plus I'm a 13 year old and I don't have time to make a highly sophisicated engine. (I can't even spell much less make a revolutionary engine) :). Just an opinion, wakawaka54 HALO 2 CHAMPION!! :) :) :) :) Dam i have a math test on friday... Tag: XNA Game Studio Express Invert screen Game Technologies: DirectX, XNA, XACT, etc.

    - C# Express SP1 - Need to install? I've installed it and I haven't had any issues so far when coding 360 projects. I'm not sure how (if at all) it affects Windows development, but I'm going to guess there's no change. By the description, it's just bug fixes and stability improvements (just to the IDE as far as I know, or else there'd be an update for .NET too), nothing should be breaking your XNA install.

    - release date of font stuff? I haven't heard anything. However, I picked up on this a few weeks ago. http://blogs.msdn.com/garykac/ Its a lovely utility to convert True Type fonts to a bitmap. XNA framework does not support True type font rendering. Instead, you can draw bitmaps (sprites). With a few tweaks (ContentManager loading rather than file system), it works a treat for font rendering (360 or Windows). Unfortunately, Gary has left Microsoft (blog echoes this). However, the example code and utility have worked a treat for me. Saved me a lot of time and effort (I had started work on saving various fonts as bitmaps).

    - Problem with new Animation sample Are you sure you selected the custom animating model processor when you added tiny.x to your project By default it will just pick the default ModelProcessor, so you'll have to change that to specify you want to use the animation system. I definately tested that code with Tiny, so I'm pretty confident she works with it (although she'll probably come out the wrong way up and a silly size, since she wasn't modelled in the same units as our new dude mesh).

    - Can't deploy to Xbox 360 from GSE I would try the following - disable firewall on PC, reboot - configure your PC and Xbox to static IP address - get a switch/hub and put your PC and Xbox to it - now try the deploy again If that works, try restore your IP configurations (if you were using dynamic ip before) If that works, try going through your router wired If that works, try going through your router wireless If that works, trying to restore other settings (firewall..etc) one by one until it fails. If you can't deploy without firewall, over a single hub/switch with static IP, then have to check for something more basic, like: - make sure your cables work - try to deploy without a hub/switch, using a cross-over cable (in theory it should work) - run "netstat -ab" from DOS to make sure nothing is hogging the needed ports - check task manager to make sure you don't have any other anti-spyware/anti-virus software running Other than entering the incorrect codes, or not having your xbox at the Waiting for Connection screen, I havn't seen the timeout error before.

    - How to get a lit sphere colored sphere/cube in XNA After a lot of reading it seems with the exception of writing my own Model class (which will take me far to long) my only hope is to find someone who has written an equivalent MDX Mesh class in XNA, but i haven't found any yet, so I if noone knows of a user made Mesh class for XNA I guess i have no choice but to go back to using MDX. Is there anyway to suggest this feature in future versions of XNA As much as I like XNA, the lack of a mesh class means for my personal use, i'm far better off using MDX.

    - Geometry instancing support on 360? I think the reason is that for the GPU band games (most of the big XBOX 360 games are of), the instancing gives no performance benefit at all. Also if you have a modern PC with Core2Duo you'll generally hurt your performance with this technique. And R2VB does not supported by XNA yet.

    - Fullscreen and multimon Well I would like to know if there is a better/proper way to do this, but this is how I resolved the issue. I added a new method to my framework which detects if more than a single monitor is installed on the system. If so, rather than use DirectX to create a fullscreen device I instead change the display settings of that monitor and create a window to fill the screen. Removing the borders and setting the window to topmost gives the illusion of fullscreen. Which leads me to another question. What are the benefits of using direct3D's method as opposed to my workaround To be honest, I see none: 1. using Direct3D the front and back buffer must have the same format. Using an expanded window it's not so important, but if they are not the same it requires color conversion. 2. Using the window api's can be a pain, if the game crashes the resolutions will not be reset. Direct3D will , 99% of the time, return all modes to their origional state. 3. An annoyance with Direct3D on vista, the sidebar has a habit of flickering through the scene. I advise all developers to programatically hide the sidebar when entering fullscreen mode.

    - C# and XNA XNA is the technology, but C# is the programming language. MS offers a learning edition of C# (which is really a full-blown C# compiler, and quite nice!) which is required for XNA. XNA itself is really just an add-on to the C# development environment. This is the official home of XNA: http://creators.xna.com/ this is a site with some tutorials: http://learnxna.com/files/folders/videotutorials/default.aspx more video tutorials: http://www.xnatutorial.com/ page_id=46 XNA resources: http://www.xnaresources.com/blog.asp Official MS site for C# beginners (tutorials): http://blogs.msdn.com/coding4fun/ hope that helps. //edit: something else you might want to be aware of: XNA provides the codebase for building games, but other essential elements, such as game engines, map builders (for 3D) as well as 2D game engines are not a part of the XNA framework; you'll need to track those down yourself. Luckily, MS is offering a license for TorqueX with a year subscription to the XNA developers network. For about $100, you can't beat that!

Is there a reasonably easy way to invert (make a negative of) the whole screen

TIA,

David.

Re: XNA Game Studio Express Invert screen

manders

I haven't tried this but...it's worth a shot.

Draw a fullscreen quad or sprite (contents do not matter), with RenderState.SourceBlend = Blend.InvDestColor, and RenderState.DestinationBlend = Blend.Zero.

See http://blogs.msdn.com/shawnhar/archive/2007/01/02/spritebatch-and-custom-blend-modes.aspx for more info on setting blend modes.

Re: XNA Game Studio Express Invert screen

Shawn Hargreaves - MSFT

That will work, but you'll have to make the source sprite white to get correct results.

The standard blending equation is SourceColor * SourceBlend + DestinationColor * DestinationBlend.

With SourceBlend = InverseDestinationColor and DestinationBlend = Zero, that becomes to SourceColor * InverseDestinationColor + 0. If SourceColor is white (aka 1), the end result is just InverseDestinationColor, but other SourceColor values will give different results.

If you set the blend to SourceBlend = InverseDestinationColor and DestinationBlend = InverseSourceColor, you could even crossfade between normal and inverted rendering by fading the source color from white to black!

Re: XNA Game Studio Express Invert screen

Thanks both for your speedy replies -- it did the trick.

My project isn't too graphically heavy so I haven't really looked intot the blending modes.
