• DmitryMS Model Position Problem

  I have this code that creates a model at the position of the mouse click but the model never shows up at that position. Maybe someone out there knows why the models seem to be offset. If I click in the top left corner of the screen, the model shows up in the center of the window. Here is the code: #region Using Statements using System; using System.Collections.Generic; using Microsoft.Xna.Framework; using Microsoft.Xna.Framework.Audio; using Microsoft.Xna.Framework.Content; using Microsoft.Xna.Framework.Graphics; using Microsoft.Xna.Framework.Input; using Microsoft.Xna.Framework.Storage; using System.Collections; #endregion namespace Commander { /// <summary> /// This is the main type for your game /// </summary> ...Show All

• stuntpope Depth of GameComponents?

  Hey, I've been trying out some features of XNA and I noticed that one really necessary feature is missing... there is no way to set the order in which game components are drawn in the existing framework. I would really appreciate a Depth or ZOrder property of the GameComponent class and a Sort() method for GameComponentCollection. Maybe there is another way to do this, but I would find it a lot easier than using the Insert() method, since developers may want to change the order after adding the component. This is probably a pretty crude explanation as I haven't given that much thought to it, but it still seems that some sort of solution to this would be very useful. Please tell me what you think or plan to do - thanks. ...Show All

• Blackwood Vista allows What versions of DirectX?

  (split from http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=1221168  to make a new question) It is interesting that you say that because I am testing a VB6 app that was working fine on XP and below but now fails on Vista when it tries to create a DirectX8 object, specifically Set oDX = new DirectX8 throws Error 429, ActiveX failed to create component. Running in XP SP2 compatibility mode does not work either. I would be really grateful if anyone has any ideas on this.  I also tried running the latest DX9 redistributable because I heard that was providing backward compatibility, but to no avail. Thanks. I am awaiting a reply from the DirectX team - their response tim ...Show All

• Darren.Sim How do I apply a material made in 3DS Max to a model in my XNA game?

  I want to use 3DS Max to make a material and then use that material on a model in my game. The following is what I'm trying to do to accomplish this. Advice on any step would be appreciated as I'm lost in several areas. Step 1) Create a material in 3DS Max . Ok I can do that. Step 2) Export the material as a .fx file. I can do that too. But when I do, 3DS Max generates a .hlsl file in addition to the .fx file. What do I do with that file In the XNA docs, there is info on how to implement pipeline stuff to import HLSL source files. Should I do that If I do do that, how do I tie the resulting PixelShader to my model Also, my texture and bump maps in my material aren't saved along with the .fx file... how do I get those into my Effect i ...Show All

• Mystagogue 3D picking with the mouse combined with a moving camera...

  Hi all, I'll get right to the point. My camera is defined using the following code... cameraworld = Matrix .CreateTranslation(xplane, yplane, 0) * Matrix .CreateScale(zoom) * Matrix .CreateRotationZ(angle); view = cameraworld * Matrix .CreateLookAt( new Vector3 (0, 0, 100), Vector3 .Zero, Vector3 .Up); projection = Matrix .CreatePerspectiveFieldOfView( MathHelper .ToRadians(45), ( float )graphics.GraphicsDevice.Viewport.Width / ( float )graphics.GraphicsDevice.Viewport.Height,1.0f, 1000f); effect.View = view; effect.Projection = projection; I've also got code to allow me to place objects in the game world, after unprojecting the mouse points and finding the point of intersection with my XY plane.

• Jan Byvaly UK XNA Launch Event

  Just a quick shout-out to anyone heading to the XNA Launch Event at the University of Warwick tomorrow. Had a quick look again through the event programme and noticed Mitch Walker is presenting "XNA Game Studio Express end-to-end" in the morning. There was me wondering why he'd not got back to me on one of my questions then it clicked he's presumably been on a long flight to the UK today. :) Got Chris Satchel and Peter Molyneux presenting during the day as well, should be good event! Adam Miles Thanks for that info Adam. Makes me wish even more that I could have attend the event in Redmond. I could have used a new t-shirt at least. Well, I hope some other guys from the forum were there t ...Show All

• r3n XNA Quake bin release 2

  New release of my Quake port to XNA. This one as a lot of new features like player walk, weapons (axe and rl), teleports and items. I still don't have help on this so things move slow. http://perpixel.dyndns.org/~guillaume/xna_quake_release_0.02.zip Enjoy! You will learn tons more if you port it yourself. ;) Its crashing because you didn't copy the original Quake data file to your XNA Quake folder. Its not possible for me to ship this with this data included so if you don't have those file just grab the demo from id software FTP. Please read the README.TXT included with the release. I did release the bsp loading source code on my blog at http://perpixel.spaces.live.com/ and I plan to release ever ...Show All

• Please help with my query. Collision detection - Howto

  Hi all, I'm trying to make two objects collide in GSE, actually in a Pong game - between the bat and the ball. I have motion for both, but no collision, the ball just leaves the stage so to speak. Any help would be appreciated. I have looked in the Help, but to no avail. Thank you so much I like totally didn't think to put the x y locations in for vector locations. Thank you again. so the question remains if you have a sprite on the screen how do you assign the Bounding Box do it Do you need to do a vector that moves with the sprite LIke masked over it in a sense What was the code you used to assign it to a bounding box I feel like a moron because I have been messing with this and am completely missing ...Show All

• Jesper25539 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 I'm not sure which language they are using, but Vanguard: Saga of Heroes is being developed on the XNA platform: http://www.gamespot.com/news/2004/05/10/news_6097001.html part=rss&tag=gs_news Well Vista includes WPF for development (though don't forget WPF is also availalbe to download for WIndows XP) so WPF might make more managed developers (not just c#). Remember though that WPF isn't really about games, well not high performance ones, so that probably won't increase managed co ...Show All

• NETLAND Audio Question

  Sorry if this has already been answered but I don't really have time to look for that answer here it is... It has come to my attention that the October 2006 DirectX SDK has come out and has a version of XACT different from the August 2006 so... Does the current version of XNA Game Studio Express support the XACT version on the October 2006 DirectX I would have to spend another 3 - 4 HOURS downloading the other version so please anwser soon... Dude, I don't believe you will accept ( or else.. not like it) if you have an download limit, or some else of network limitation. half a gig is not nothing.

• Jeanet RTS Camera

  Hi, I've went through any XNA game component, tutorial or forum thread out there and still can't find an example for what I need. Maybe someone could enlighten me or point me in the right direction! Trying to create a basic RTS style camera. The thing is when doing composite rotations no matter which axis I feed to the Rotate() method, eventually "yaw" and "pitch" rotations composite into a "roll". I want to keep my camera's roll level with the XZ plane. I tried using both "world" and "camera" up and left vectors for this. Didn't work. What do I need to do I recommend you forget about the yaw/pitch/roll thing and model this using Matrix.CreateLookAt(..) ...Show All

• Levas MDX/C# GDI+'s ColorMatrix equavilent to Pixel Shader 2.0's... ?

  Hi. Would it be possible to transform colors with Pixel Shader 2.0 similar to GDI+ with C# This is to say that if I have 2 images -- day and night image, which I blend from one image to another, which I can do that with GDI+'s ColorMatrix class. But as resolution gets bigger, so will the GDI+ that will have to redraw at a slower rate, such as a resolution of 1920x1080. Direct3D (and the depricated DirectDraw) are faster than GDI+, so I wanted to take into account with the use of Pixel Shader 2.0 (or maybe 1.1) for smooth rendering. Just to let you know in case you'd might ask, I'm building a multi-media application--probably with DirectShow.net but I'd probably make use of new Vista's video technology for digital TV tuner but I bet i ...Show All

• Philippe Cand Game Distribution

  I am trying to get a very simple 2D XNA game to run on other peoples machines; but when I send them the relevant files, they all complain of getting some form of error report. They all claim to have the requirements (XNA Framework, latest DirectX and .NET Framework 2.0) installed, but it seems something, somewhere isn't doing its job. One of the people in question only has a Radeon 7000, so it is understandable why it isn't working. But the other two have a GeForce 6800 and a 7300GS which should be more than enough! I have tried both ClickOnce installers and binaries from both Debug and Release directories. They all worked fine in folders on my machine, but on other computers the installers installed fine, but just throw up a windows error ...Show All

• Dan_Brownlow Controlling Game By MIDI

  I'd like to be able to control directx games via MIDI - eg use a guitar footboard that has a pedal and switches etc to generate game controller events. All the vaguely related references I've found on the web are for using directx controllers to generate MIDI events! I want to use MIDI events to generate the equivalent of key presses, mouse buttons or (say) a throttle control. Are there any drivers that do this already If not, how difficult would it be to roll my own, and what would it involve I'm quite competent at C/C++ etc but most of my experience is in an embedded environment, not Direct X.

• malkie XBox 360 hard drive question for MS staff - semi off topic

  With all the great new offerings out or coming soon for the 360: XBox Live Video Marketplace, XNA game creation, and the recently announced IPTV, the poor little 20GB hard drive's days look numbered. Is MS planning to release a larger hard drive for the 360 I'm pretty sure that many people (including myself) would be very interested in one. drawle wrote: I don't want to replace my box either. I wish we could write to external USB hard drives and flash drives rather than using them read only. The more we can comfortably store, the more we might buy... I may be wrong, but MS could probably cannibalize the majority of parts from the current 360. It would be cool if they roll out the Zephyr ...Show All
