• nbot Problems opening new project

  Hi all, just downloaded XNA beta. I keep getting an error when trying to create a new project. It doesn't matter if I choose empty project, windows game or spacewar, I keep getting this error (translated from the dutch error message): the syntaxis of the filename, foldername or volumename is incorrect. (Exception from HResult: 0x8007007B) Any ideas I checked my folder settings, but they seem to be in order (existing folders...). Kind of a bummer, since I can't do anything until I get this fixed. thnx in advance You're running C# Express under Win XP right Hi, just found the answer to my own question: this is a known problem using C#. Has to do with directorynames containing an am ...Show All

• worldhello Core 2D game engine, book recommendations?

  Hi all, I am looking for a decent book or two on game development for someone with fair OOP programming experience. The book should give guidance on the the following subjects:  * What to do in the core game loop  * Handling animations (in the core game loop).  * Handling events, or triggered events.  * Something about artificial intelligence --> Path finding.  * Ideally, some tips about multiplayer integration.  * Going about with various exceptions (which makes the game).  * Working with tilemaps.  * Enemies moving on a tilemap + pathfinding.  * All of the above in a OOP approach.  * preferred is the main focus design of above, with code examples. Basically a book which can ...Show All

• Ziad Adada Creating a simple Box with D3DXCreateBox

  Hi, i have a problem with D3DXCreateBox. I simply want to render a box of size 100, 100 and 1 in a windowed application. So i have the following: void render( ){ //Mesh LPD3DXMESH mesh; pD3DDevice->Clear( 0, 0, flags, D3DCOLOR_XRGB( 255, 255, 255 ), 1.0f, 0 ); pD3DDevice->BeginScene(); D3DXCreateBox(pD3DDevice, 100, 100, 1.0, &mesh, NULL); mesh->DrawSubset(0); pD3DDevice->EndScene(); pD3DDevice->Present( NULL, NULL, NULL, NULL ); //this is ugly but works mesh->Release(); buffer->Release(); } When i call render in the main loop it only clears the scene but does not render the box. while ( 1 ) { // Only render when there are no messages if ( P ...Show All

• Marius Onofrei Xbox360 to PC Comparison

  Does anyone have an idea what performance I can expect from the Xbox360, I am writing my game purely for the console because I dont want to have to write a load of code for dealing with different spec machines (throttling the number of creatures, etc) and different types of input. The game I am porting is this (original is in vb.net and MDX) - http://www.entombed.co.uk I have managed to port the models, parrallax occulsion mapping shader and per pixel lighting. But I dont know how the Xbox360 is going to perform. My PC is this spec ( cr@p ish) - Intel P4 2.4 (400 FSB) ATI X800 XT PE 768 MB AGP x4 I am receiving an excellent frame rate from my PC and wondered what I should expect from the console, will it be twice as quick or mo ...Show All

• TonyVFP other operating systems?

  will XNA ever be available for linux, mac, or other c'mon at least mac! Well, we really don't know very much at the moment. I can redirect you to the site of the Tao Framework that is starting this development. If you are interested you are welcomed to work in it, just sign in . But as a starting new baby technology (actually a baby technology even in Microsoft) we will see. I definitely believe that XGL will be the way to go but... Time will say. www.taoframework.com/Mono.Xna Cheers That would be great, probably we can think of XGL exposed like WPF is Microsoft hasn't said anything about it by now but historically, DirectX has never been deployed for any other OS than Windows.

  Anyone know what i did wrong You missed a semicolon and Load should be capitalized.

• Karen G. Solution for people that can't upgrade directx from 9.0b(or 8.1) to 9.0c {windows xp users}

  This thread is for people in two scenarios: 1) Those that can't upgrade their directx version from 8.1(standard windows xp starting version) 2) and Those that can't upgrade their version from 9.0b to 9.0c. Today is your lucky day! These two solutions largely will work for people who keep trying to upgrade their version of directx and continually get a dialog box appearing, which says, “The components installed are now ready for use.” That being said, these poor unfortunate souls(myself included up until an hour ago), know better, as they check the diagnostic tool and see for themselves the version has not changed and they are stuck in version 8.1 or 9.0b. I spent an accumulative of 6 hours on the phone with Microsoft technical support a ...Show All

• Elurahu Should shaders be getting disposed on device reset?

  Under MDX 1.1, once a vertex/pixel shader was compiled, the resulting compiled shader was good for the life of the application, and was still valid even after a device reset. However, under XNA, compiled shaders seem to go into an invalid state when the device is reset - attempting to set GraphicsDevice.VertexShader to a shader compiled before the device reset results in an AccessViolationException. Has the requirement on needing to compile shaders after a device reset changed between MDX 1.1 and XNA, or am I looking at a potential XNA bug OK, I will create a minimal example that reproduces the issue and post it as a bug. Thank you for the fast response. phoenix11 w ...Show All

• piekop N00b Maths question - calculating radian angle for rotation of a sprite based on two points in 2d

  Apologies for my poor mathematics here, but I need to ask the greybeards for some advice: I have two points on a 2d plane, offset so there is one "top-left" and another "bottom-right". I need to join these two points with a straight line by scaling a single dot sprite from one point to the other. If I know the x,y co-ordinates of both spots, I can get the overall length of the scaled sprite, but how do I calculate how far I need to rotate the scaled sprint around one end point to "join" the points together Thanks in advance for any help you can give. P " There are other ways to solve that problem without rotating a dot sprite, but I will assume you have a good reason for ...Show All

• Anurag Srivastava Woeful XNA GSE Install

  I've uninstalled my XNA GSE Beta 1 and everything but I get that stupid error message whenever the installer gets around to installing the DX Runtime. I never had this error when I installed GSE Beta 1, so why now It finally worked, but I only launched the .msi file through Run. Does that mean you can't just run a Windows Installer file through Explorer, you have to use Run If your still having trouble please follow this guide: Please try running the installer like this: Msiexec /i xnagse_setup.msi /lv installlog.txt In addition to that if you want to grab your %windir%\DirectX.log (%windir% is the root windows directory) And file a ...Show All

• Ralph1988 TitleLocation writeable on the 360?

  Let's say I run some code like this on the 360: string fullpath = Path.Combine( StorageContainer.TitleLocation, "new_file.dat" ); FileStream fs = File.Open( fullpath, FileMode.Create, FileAccess.Write ); Will this work on the 360 Or is "TItleLocation" read-only Assuming this will work are there any FileMode operations that are off limits in TitleLocation or it's subdirectories If this can be done, then is there any limit to the amount of space that can be written to TitleLocation or it's subdirectories other than the available free space on the 360 HD Thanks - Ryan If you don't get an answer on this in a couple hours, I'm going to try to run some StorageContainer/ ...Show All

• fel lobo Vibrate the controller for 1 second?
