• rdeal3 Intersection test problems

  Hello, I am trying to get our hierarchical BV culling working properly and I'm experiencing some odd behavior with the BoundingFrustum intersection test. The problem is that when I test my BV's against the frustum the test is not accurate. I am testing spheres and AABB's against the frustum but let's just talk about spheres as I have the same problem with every primitive. What I have found is that the accuracy depends heavily on the setting I use for the FarPlane when we call Matrix.CreatePerspectiveFieldOfView. When I set the FarPlane to a big number (like 4700 for example) the camera has to be almost looking in the opposite direction to the sphere in order to get the sphere to fail the test. If I set it to a very small numb ...Show All

• Oscar Marin Request: Add New Item --> DrawableGameComponent

  Currently only 'GameComponent' is selectable when adding a new component. It would be nice if 'DrawableComponent' was also available in the list. I agree that it would be nice to have a template for this. Be sure to submit suggestions and bugs via Connect - thanks! https://connect.microsoft.com/site/sitehome.aspx SiteID=226 Amy ...Show All

• JoneLee low resolutions not working (<800x600)

  Hey there all! I wonder if someone of you has experienced the same problem like me:  I'd like to set up my game to have a resolution of 640x480 fullscreen (or even lower). When I make a new game project (or open an existing one - doesn't matter) and change the resolution to anything lower than 800x600 fullscreen a messagebox appears (while the game starts fine, but stays a black screen doing nothing) saying that I will have to use a resolution minimum of 800x600 to use this application. I was searching for the text in the messagebox on the net, but to no avail. I'd post a picture here, but since my WindowsXP is a german version, I guess that it wouldn't help a lot. Maybe this even has nothing to do with XNA or C#. My gra ...Show All

• charlestek D3D Mesh Object does not exist...and Spacewar is using new "swm" format?

  Looking at the SpaceWar sample...I am wondering if there is somewhere a converter from .X or .XBF to the SWM format. Looking at the loader in the Simplemesh.cs class, it looks like the SWM is using a propriatary header and than the binary .X format.. Can anybody help with this format I would love to use 3D Max and export to .X than read it into my game...but without a code converter to SWM...hard:-) I created a .X to .SWM converter. x2swm - http://astaroth.beatbuggy.net:8080/Downloads/x2swm.zip It's not properly tested, so let me know if it works ok. It was mentioned in another thread that the guys that did the Spacewar game had a utility that converted from .x to .swm, and they were going to see if we ...Show All

• Seethar Voiding xBox 360 warrenty

  Someone told me that if I deploy my project to my xbox 360 along with the xna framework it would void my warrenty. Is this true I doubt it. Unless by "deploy" you mean "take hard drive out and copy your project onto it directly". No need to worry. Btw, you deploy your project onto the Xbox using Game Studio Express via the network. The launcher has everything necessary to run your compiled project. No need to send the "XNA framework" to your box. Ok, I just wanted to make sure. No I'm not taking out the hard drive, I'm wanting to use the XNA Game Launcher that will be installed onto the 360, and I wasn't sure if the xna framework was ...Show All

• pmxinos Scorched Tanks for Windows (and 360)

  Hey, Continuing my habit of starting more games/projects than I can ever hope to finish, I decided on Thursday I'd write my own version of Scorched Tanks in XNA. What I've got so far is by no means close to being a game, yet, you could probably "play" around with it for 5 minutes or so, so call it what you will. It's working on 360 and Windows (without code changes of course) which is good news. What I've zipped is really just a work in progress for people to play around with and ask any questions (should there be any). The code is, as with all works in progress, fairly atrocious, so I'll keep it to myself for a bit but if by a miracle I've done something and you want to know how I'll happily tidy up the relevant bits and post it. ...Show All

  ok guys and girls a lot of people think you cannot use vb.net with XA, well either I am crazy or I am a wizard, it can be done the same way you do with c#, I have code for all the vb.net users who wold like to try it on my website, http://www.tridexconsultants.co.uk/pages/DirectxClasses.htm I am just waiting for the conetent pipe line stuff to get some animation into the models!!!!

However - someone posted something similair in that they started a vb.net project and just referenced the XNA, which worked. BUT som ...Show All

• kewpcg Any suggestions for defining direction of partical effects on a 3D model?

  Hi all: I'm still playing around with XNA and figuring out what I can do with the current state of the technology. What I want to do is have a 3D model of a spaceship that has RCS thrusters and a main engine. The RCS thrusters and main engine will all have a particle stream to simulate rocket exhaust. Somehow, I need to define the size and type of rocket exhaust, and what direction it should take, and do so within the context of the XNA framework. I presume I'd need a custom processor for the model to identify where rocket exhaust nodes are (think named invisible cubes in the 3D model, like "MainEngine" and "YawRight"), but I'm stumped on how to define the direction of the particle stream in relation to the model ...Show All

• Imanol XNA with C# Professional version

  I can find any of this in the FAQ so I'll ask: Is there a way to get/install and use the XNA framework with the professional version of C# My Visual Studio Professional already as C# installed. I'd like to be able to play with XNA without playing to many installation games Thanks, Gary Only the installer itself depends on C# Express being present. So, install it to make the installer happy, uninstall C# Express, and reference the XNA framework from any version of Visual Studio that you like. Working with it with Vb.Net in VS2005 Standard Edition atm. (I do understand that it won't work on the 360 doing that as the vb libraries aren't on there yet, but I don't have a 360 making it a null point for m ...Show All

• Northern Rob Managed C++ DirectX Devices

  I recently upgraded my Windows::Forms application to use DirectX with Managed C++ (instead of unmanaged C++). Ever since I did it I get exceptions with the following line (even if before I succesfully built and ran my application, containing the line, several times, ) : DeviceList * deviceList = Manager::GetDevices(DeviceClass::GameControl, EnumDevicesFlags::AttachedOnly); (by the way is this an appropriate way for enumerating devices in Managed C++ I only found C# samples) Reinstalling DirectX solvds the problem once but now it is happening again. Should I avoid using the managed c++ version for this application Creating a Direct3D Device is also problematic: PresentParameters * presentParams= new PresentPara ...Show All

• chire Why I can't see any game component in VC# express 2005 toolbox?

  After I saw the demo of game component video from XNA team blog, I want to try.But I can not find any game component in toolbox. What is the problem Perfect Thanks! Thanks mrMercury - I got that part - but I'm looking for the code (or just the components) for the ones that were shown in the demo (grid, camera, etc.) I just watched the game component demo - those are great components to add to a library and to learn from. Will someone make these available in the near future Thanks! follow the link its a really cool idea by the XNA guys to have components for games design in ...Show All

• spree Content Pipeline Output Path

  Using the content pipeline, how do I get the output path Because I'm working with assemblies I can't use the xnb files (I have to load a file off disk by passing the filename to LoadAssembly) Previously I required the pipeline DLL was placed in the output directory, and used its location where to stick my files but this isn't working for some complex assembly reason mentioned in another post. What I really want is a way of finding the path of the xnb file that is normally produced and creating my file in the same place In a ideal world I could also inhibit the output of the xnb file and tell the dependency checker to use my file... I haven't seen anything about changing the output file in the content pipeline but this could just be I have ...Show All

• aamer4u C# Express and VS Pro

  Hi, I have VS.NET 2005 Professional running on my pc. Now when i try to install XNA Studio it says i need C#.NET Express installed on my pc. Will the express version and vs pro run without any conflicts on the same pc Why does xna only support express version You can install C#.NET Express on a computer that already has VS 2005 Professional. They work side-by-side. "Why does xna only support express version " Well... XNA itself it's an "Express" version, isn't it Yes both pro and express can co-exist. Actually I'm running it this way and it works fine for me. It is little annoying that the xna integrates only with express and exp ...Show All

• Victor Nakoryakov BoundingBox.Contains doesn't work after a transform?

  Hi All, I have some test code that uses BoundingBox.Contains to see if a vector lies inside the bounding box. It works fine until I transform the point vector and bounding box min/max vectors by a matrix. The coordinates look right, but the function retuns disjoint. I know I must be missing something here, but I can't figure it out. The values after translation are: BoundingBox.Min: 0, 0, 0 BoundingBox.Max: 1, 0.99999999, -1 Point: 0.5, 0.5, -0.5 My test code just replaces the standard game Update() method. You also need to set the game Draw() methods graphics device clear call to graphics.GraphicsDevice.Clear(color); Here's the Update method and color declaration: Color color = new Color ( Color .Yellow.To ...Show All
