• Dan Scott How do I set The PrefferedBackBufferWidth and Height?

  Im learning XNA but it says PrefferedBackBufferWidth isnt a variable, Im trying to set the size of my application to 800 x 600. Thanks That looks hard! In the constructor for your class derived from Game, you should create an instance of the GraphicsDeviceManager class. After creating this instance you can set the preferred back buffer dimensions: public class MyGame : Microsft.Xna.Framework.Game { GraphicsDeviceManager graphics; public MyGame() { this.graphics = new GraphicsDeviceManager(this); this.graphics.PreferredBackBufferWidth = ...whatever you want; ...and so on... this.graphics.ApplyChanges(); } } ...Show All

• eric shih Installation fails to register extensions

  No matter what system I try to install this on they all run vista and all attempts fail. It says it installs the Game Studio Express successfully, which it seems to do so. Then I open Game Studio Express and go to File->New Project, and the starter projects are not there. Any ideas/work arounds Thanks. I'm running Vista Ultimate on all computers attempted if that helps. Check out this link: http://nuclex.org/articles/xna-game-studio-express-1-0-on-vista By the way, Vista is not an officially supported platform for XNA. The only officially supported platform is Windows XP SP2. thanks that worked ...Show All

• eevee Is there a way to get the color of the pixel under the mouse pointer?

  Hello! Is there a way to get the color of the pixel under the mouse pointer I’m new with C#. This looks like it will be a nice platform to work with. I like to make 2D board games (Like RISK). I have worked in VB6. I need to be able to click on a land mass and identify it. And with the land masses I work with, they have very rough edges. Here is a whole tutorial on the subject from xnaresources.com: http://www.xnaresources.com/pages.asp pageid=25 And how do I change that Uint to a color .. I miss something.. The problem is I don't know the color yet I get, So its not an defined color. I need the color object. ...Show All

• Netmaster0000 Do any big game companies use C#, VB.Net or J#

  Hi, it's me again. ;) I've posted many posts in this thread, but try to stand me. Okay. This could be a silly question, but does any big game house use C#, VB.NET or J# to program DirectX Is it possible Timo What about games like Runescape by Jagex (jagex.com), for example Runescape is made in Java, I'm guessing to make it multi-platform. However, if you were to focus on the Windows platform, which language would you use Would VB or C# be enough Or would you need to make it in C++ Since this was a different question you should start a new thread. I split this one out. In my opinion, the use of C# or the like, is the way that many games will be produced going forward. The concept that you have to build a game for ...Show All

• PareshGheewala Rendering to a Texture?

  I tried to do a search but kept getting an error message. I was wondering if anyone had an example on how to render to a texture under XNA. Thx In order to write anything even remotely ambitious, you must have the ability to Debug what's going on with Direct3D underneath. You need: Visual Studio 2005 Professional. Turn on "Unmanaged Debugging" Use the Debug version of DirectX. If you have all this enabled, you should see very detailed information in the Output window whenever something goes wrong. If you don't have all this... get it. You will wonder how you ever survived without it. Thank you I need to know this too. Sorry, I should ha ...Show All

• NukeMan Ram Support

  I only have 512 ram and am going to upgrade to 1g, should i leave the 512 in and make it 1.5 or should i take it out and make it just 1g because i have been told that it dosent like it when you put in multiple sticks and it works well with one stick Although this is not the proper forum for that question, you should have no problems installing 1.5 Gb. Just make sure you buy the proper ram and voila. Ask your vendor anyway for an expert opinion. ...Show All

• MartinMalek Drawing a simple rectangle

  Hello - I'm trying to use XNA to draw a simple rectangle at the moment, using DrawIndexedPrimitives. I've tried tweaking and adding many different things but I can't even get anything to show, just the plain black screen (and yes, everything else like textures are rendering fine). Here's my code: Declarations: Protected vb As VertexBuffer, ib As IndexBuffer Protected vertexData As VertexPositionColor(), indexData As Integer() DeviceCreated event: vb = New VertexBuffer( _ graphics.GraphicsDevice, _ GetType(VertexPositionColor), _ 4, _ ResourceUsage.WriteOnly, _ ResourcePool.Managed) ib = New IndexBuffer( _ graphics.GraphicsDevice, _ GetType(Integer), _ 6, _ ResourceUsage.WriteOnly, _ ResourcePool.Managed ...Show All

• jararaca 2d Platforms

  I understand it'd be pretty difficult to help me with a problem with me just describing it, without seeing code so... http://skynes.tripod.com/TheWizard.zip There's a link to a zip file containing my XNA project and all images. The Project so far is a mix of a couple of tutorials I found online (2d wizard and a tile engine) along with sprites I found online. I haven't made any of my own sprites yet cause I don't see the point until I have everything working, but I will be using all my own original sprites when it works. Anyway. So far it's a wizard who can jump and shoot fireballs. An enemy (movement currently commented out) walks across the screen, firballs dont do anything yet, but touching the enemy costs you a life.

• DannoCoy Invisible Skybox

  Hi i have used some of the code from the SkyBoxDemo tutorial to make a skybox in my game. I adapted the code to run with my game but when i debug the game i cannot see the skybox and my model following camera flips round to face the front of the model insted of the back and The Ship model turns weird colors!   but wouldnt moving the skysphere make everything go wrong, If the skyphere is always located where the modelPosition is then to alter the skyspheres location you would have to do a sum on the model position vecter which would change were the model is and most likeley dissapear the skybox. Is there an easier way than this :D -Thanks- ...Show All

• a_takavci Ogg support in XNA?

  Hi I just wondered if and when there will be support for Ogg Vorbis (or wma, or something) in XNA (Xact ). Anyone know Having to use wave files for music is really not that great. Since XACT loads and converts everything to its own format internally this will not save any space. (I'm not totally sure what an mp3 encoded wav file is anyway, but rest assured there is no mp3 decoder on the 360) To answer the original question - there is no Ogg support in XNA, nor is there the facility to add it yourself. Requests for future features should be added in http://connect.microsoft.com I think ryan was talking about real time decoding mp3 >> streams >> Pcm - Wav >> Xact. And as I was long time looking fo ...Show All

  Here is another breakout game. Screenshot Download Source Here http://conkerjoe.no-ip.org/breakout.zip Its now ready to build some funky levels into it.   :) You sure can. i have signed up to 360homebrew but am unsure of how to add stuff Sorry about that. I will make the Add Photo link bigger. It is on the right sidebar after you are logged in. I see that you found it. Quite fun, indeed, I liked the speed of the ball, reminds me of my project. Anyway, I tried using the 360 controller until I realised that it was keyboard-only (360 controller support is very easy, btw) all-in-all very fun.

• Vincent-Philippe DIrectX 9 - Virtual Trackball to rotate object

  Following this tutorial http://viewport3d.com/trackball.htm I'm trying to implement a "Virtual Trackball" to rotate a 3D object, in 3DS Max style, with DirectX 9 using the mouse. I've anderstood how to calculate the spherical coordinate on the virtual trackball from the planar ( X,Y) coordinates of the mouse in my picture box, and than how to calculate the rotation express in terms of an Axis and a theta angle... But form here, I can't anderstand how to use this information to rotate my object because the tutorial uses the "quaternion" function to move the camera around the object. I'm not be able to make the same, so I'm thinking aboute the possibility to use a normal rotation around the canonic X,Y and Z axis, u ...Show All

• WildRich How Do I Determine The Currently Visible Area?

    I'm building a 3D game and currently have everything working, but I'm in the process of optimizing my framerate.  The world in the game is many times larger than the screen/window.  How would I go about determining the world coordinates that are visible on the screen   Even though the objects outside of the viewport are clipped, the draw code still has to translate (and rotate) the meshes in the objects (many of which will be clipped).  It would be much more efficient if I could just not process meshes that will be outside of the screen.  Thanks!   Thanks, if it is the answer please mark it as such to help others!

• tamri Microsoft C# Not C# express

  Say if you used the real C# not the C# express would there be more features than C# express. Additionally, you could try and use Subversion ( http://subversion.tigris.org/ ) or TortoiseSVN ( http://tortoisesvn.tigris.org/ ). TortoiseSVN is an offshoot of Subversion with more capabilities/features and a much easier to use interface. I am currently using Tortoise for my XNA project, and you don't need to use VS at all to check in/out files. Just another way to get around not being able to directly use Codeplex (I am not sure if they support SVN at all, probably not). well... if you want to use source control, and who doesn't express lacks that capability. We were using codeplex to house our p ...Show All
