    - Anyone else rolling their own numerics? Just wondering how many other people out there are finding that XNA numerical classes/structures fall a little short of their needs and therefore are writing their own For us, we needed to give our scene graph objects a coordinate frame where the rotation, scale, and translation transformation components are kept separate from one another; this is something similar to what is described in the book 3D Game Engine Architecture ( http://www.amazon.com/Game-Engine-Architecture-Engineering-Applications/dp/012229064X ). XNA didn't quite fulfill this niche, which is understandable as I imagine one constraint during its design was to make it easier to use. So, in the end, I'm thinking about writing my own 3x3 matrix struct, and my own Transform struct (which represents the above mentioned coordinate frame construct). Has anyone run into any problems integrating their owns numerics with XNA's Tag: XNA Game Studio Express Private Network Functionality with XNA Game Technologies: DirectX, XNA, XACT, etc.

    - Calculating normals for large mesh with no vertex to triangle info I have tried dropping the scaling and it looks the same. I have done a test, which I assume is correct, but it is a little odd. In the pixelshader I draw the surface with the color of the normal. color is nx,ny,nz,1. This image is then saved as a 24 bit bitmap and i go in an pick a pixel which I think is too dak and see perhaps a color of 90,2,7. That corrosponds to a normal of arround 0.36 0 0.02, which has a length of 0.36 and not one. This surprises me since I explicitly in the pixelshader normalize the normal. Perhaps someone can tell me why this happens. I know that there will be rounding errors here and there and that the GPU is more relaxed than the CPU, but this is a very large error. The tool you used to show the normals, it is something I can get my hands on Did it show the little normal vectors I guess I should just get to work and render them myself, but the way I render does make it a little messy. The reson there is no red might be that this is part of the planet (did I mention this is a huge round planet ) which doesnt have terrain with normals with large x components. In other places, the red will be the dominant color, so all three are output. I just recently discovered Pix, so I dont really know if it can show the normals. It can however let me debug a specific pixel, so i should probably give that a try as well.

    - How can I directly stop drawing a pixel? Ah, TexKill. Out of interest, does that also stop rendering the pixel to the depth buffer I'd imagine it would, but you never know with these things.........

    - Starting work on my GUI system I checked the website you linked to. It's structured somewhat similar to my last GUI system. Probably the most contraversial thing about my GUI system is that it will only use the GameComponent framework in a minimal way. The GUIManager (to which only one GuiScreen can be set at a time) will be an actual GameComponent, but the actual GuiComponents and GuiScreens won't touch the GameComponent interfaces or classes. I have my own way of doing these things at that level. So if you can dig that, you may still want to help me out with my GUI stuff :) As I said, I'll give you an e-mail :) Tag: XNA Game Studio Express Private Network Functionality with XNA Game Technologies: DirectX, XNA, XACT, etc.

I'm migrating from mdx to xna but I can't seem to find the xna equivalent of the mdx vertex type 'PositionColoredNormal' how do i get this vertex type in XNA I just want a texture-less colored cube with lighting, it seems strange that there is a more complex VertexPositionNormalTexture type, but no VertexPositionNormalColor type...

    - Rotation help Hi: Your question sounds like a problem I had to solve that simulates orbiting the Earth along an equitorial orbit inclined 28.5 degrees (and a polar orbit too), while simulating the Earth rotating throughout its day. I used a combination of Matrix.CreateRotationY to simulating the satellite's orbit around the planet, and Quaternion.CreateFromRotationMatrix (passing in the rotation matrix from Matrix.CreateRotationY) to simulate Earth rotating about its own axis. If you're interested, check out my Earth Orbit Demo at http://www.spellflight.com/GameModels/EarthOrbitDemo.zip and look at Planet.cs' Render function to see how I did it. Hope this helps.

    - XACT with XNA Hi I recently attempted to use XACT for a 2d game using C++, and i got an error when loading the global settings file, which i never managed to debug and so used a different audio API instead. Now i am coding audio for a 3D game using XNA and C#, the same thing happens when i attempt to load the xgs file. However it throws a much more helpful sounding Exception: "XACT could not load the data provided. Make sure you are using the correct version of the XACT tool." I have checked that i have the most up to date, december 2006 version of XACT. I heard that only the august 2006 version of the actual creation tool works with XNA, is this true it seems a bit silly if it is, does it mean i have to use the august 06 version of DirectX if i want to use XNA properly Is there anyway of just downloading august 2006 version of XACT without reinstalling the whole SDK Also does anyone know if is there any plans in giving XACT anywhere near half the useful features that DirectSound has Thanks :) Tag: XNA Game Studio Express Private Network Functionality with XNA Game Technologies: DirectX, XNA, XACT, etc.

    - Multiuser games? @jackline Yes, lots of people have created C# multiuser environments. Just look up client/server projects over at The Code Project, example (http://www.codeproject.com/cs/media/mdxsnake.asp). Easy, and good for a small number of players. That said... I've seen some MMOG C# projects, but honestly they don't get far off the ground. Mostly because it's hard to get the kind of support you need to make an efficient MMOG system. But also because an MMOG server should never be written in anything other than C/C++ simply because of the amount of data you need to move and info you need to process. One should never say never...but you do lose 15-20% performance moving to C/C++ to C#, possibly more depending on your code, and memory consumption is going to be a lot comparatively speaking. There are few situations where performance must be maxed out, but an MMOG server is most definitely one of them. At least for now, until server hardware becomes so wicked sick that it just doesn't matter. (but don't hold your breath) But don't let me stop you, go for it. Because at the very least you will have learned a great deal about MMOG server design. For reading, I highly recommend these two books. http://www.amazon.com/dp/1584502436 tag=hardcodedgame-20&camp=14573&creative=327641&linkCode=as1&creativeASIN=1584502436&adid=09H2VPH0YSVXGARZ43NY& http://www.amazon.com/dp/1584503904 tag=hardcodedgame-20&camp=14573&creative=327641&linkCode=as1&creativeASIN=1584503904&adid=15R6GYP3DEK9TCTXGXDH& Tag: XNA Game Studio Express Private Network Functionality with XNA Game Technologies: DirectX, XNA, XACT, etc.

    - Could C# be the future of gaming? Hi Jeff, As some one who is a partner in a company (and lead developer) that produces enterprise high performance security applications, many of them in C#, I think you will be very surprised what you can do with C#. I develop in C++, C++/CLI (.net C++) and C#. C# is my favorite by far. While it certainly takes a lot of care and research to get the "barn burning" speed you can truly get out of C#. Once you know what to avoid and how to write performance critical apps in C#, you will only go back when you have to... Enjoy learning C#, and be sure to grab the "CLR in C#" books by MS press. It will "show you the light" as far as the inner workings of the CLR and how to make your managed code nearly as fast (and in some cases faster) then it's unmanaged counter parts. It certainly helped my apps go from pretty fast to very fast... You already mentioned the "time to market" benefits of the .Net platform so I will simply agree with you and leave it at that.

    - ID3D10Effect::Get**() - what happens when handle isn't found?? Morning all, Just made a dumb mistake with my code that cause a bit of frustration. I now know the cause, but it doesn't make sense and I don't see how to fix it I had some simple code along the lines of: ID3D10EffectTechnique *t = g_pEffect->GetTechniqueByName( "name" ); if( NULL == t ) { // Technique called "name" doesn't exist - error! } But D3D10 plodded on straight through this trap and eventually crashed when creating a state block during rendering (note: this is a bad error - it just hangs the app, no failed return code). A bit of investigating showed that GetTechniqueByName () returns garbage instead of NULL like previous FX9 did. There is no mention in the specs I have nor the documentation about how to check if a technique (or variable..) exists and no mention of special return codes to check for... So, anyone come across this I'm hoping I'm just doing something stupid here - I can't understand why there wouldn't be a way of checking this sort of thing short of complete enumeration of the effect. Any help is appreciated! Cheers, Jack Tag: XNA Game Studio Express Private Network Functionality with XNA Game Technologies: DirectX, XNA, XACT, etc.

So far, in my world, i have a very small sky box, and two even smaller meshes inside of it. Everything is fine except the camera class. Currently the camera is positioned at {0,0,-50} and has a target of {0,0,0}. In the beginning of the app im outside of the skybox looking straight at it, when i press left or right, the box will move to the left of the screen, then to the right, and back. What i want to see is the skybox leaving the screen, then eventually coming back on the other side.

    - ContentManager questions about device resets Thanks, that's exactly what I needed to know. I really appreciate that you guys take the time to help out on the forums - it's very good to know that there's help not too far away! I'm very curious to know why the device recreate is not handled when the device lost is. It seems like it wouldn't be that hard to implement both if you already have one implemented. I'd be curious to know why the decision was made to support one and not the other. Is it because the recreate is expensive It seems like you'd be forced to pay for it no matter what, at least in the vast majority of situations. Thanks again!

Hey guys,

Does anyone know if there will be any networking API included with future released of XNA Im not looking for developing for Live! but for a custom client/server structure.

Any insight would greatly be appreciated.

Re: XNA Game Studio Express Private Network Functionality with XNA

Glenn Wilson

There is a current system built, you need to use the system.net classes from the .net framework.

Maybe I should have been more specific, I meant for the Xbox 360. My understanding is the system.net will not work on the 360.

You're correct. The XNA team knows this is a big deal.

Yeah the FAQ says the "next release" may possibly contain networking code. Just kinda sucks because my idea for DreamBuildPlay was basically all Network oriented.
