• Moody2006 Reading texture from a stream

  Hi, im trying to find out if there is a way to read a texture from a stream, im reading from a large file which holds loads of texture files (DXT1 and DXT3 mainly), all the information about the texture is given and then you are given the texture data. So far i have been reading the data using a binary reader and unpacking the colors into A8R8G8B8 format to use when rendering. My question is since i know all the texture info is it possible to read the texture and use it in it's original format without the overhead of converting Thanks for any help. With your own “custom” texture format things are a little bit more complex. You first need to create the texture with the necessary si ...Show All

• Chris W Multi-core programming

  Will the XNA Framework allow assigning threads to specific cores on the 360 Or more generally, how will XNA Framework interact with the 360's cores and hardware threads Shawn Hargreaves wrote: Xbox threading is somewhat different to on Windows. It is a much more explicit model: you tell the OS which core each thread should run on, and then the OS keeps out the way and leaves you to it. Wheras on Windows the OS is far more sophisticated (and heavyweight) doing all sorts of automatic allocation behind the scenes even if you don't specify an explicit affinity. We figured that since the underlying OS concepts are quite different, and anyone writing multithreaded code probably cares enough about perfo ...Show All

• espirit XNA Download

  How big will the file be I'm rumming on Dial-up and don't want ot be waiting for hours trying to download it. I hope your servers are ready! Well, I won't get any work done on non-XNA stuff at least. I'm trying to finish up a beta version of a game I'm working on by tonight so I'll be ready for tomorrow. The beta is 93MB, including 1 starter kit. This does not include Visual C# Express. I don't think I will get any work done on Wednesday. Don't worry, Supernerd. i'll have my limbless brother drag the corpse of a Pony Express rider carrying the beta on CD through the desert with his teeth. It should get to you faster than dial-up. - MrSock Pre ...Show All

• Fadzli Downloading and starting XNA Game Studio Express

  I accidently downloaded XNA Game Studio Express first without having Visual C# Express. I would like to know how do i find the XNA file to install it. I tried what you said, but it can't find it. Are there any more way to find it ----Thank You. If you tried that and still couldn't find it on your computer then you will most likely have to re-download the file. You can get the XNA download from Microsoft here . I'm not sure how your computer is setup so I can't tell you exactly where the file went when you downloaded it. But you can do a search (Start -> Search -> All files and folders) for the file "XGSESetup-Beta1.msi" That's the XNA Game Studio E ...Show All

• Kinju Form above game window.

  The main idea is the following: There is a game, which is working in full-screen mode, of course. It’s necessary for me to make some toolbar, which could work above the game window. For example, make the calculator, which will appear after clicking a button on the toolbar, but the game window is not minimizing, and the working of this application continues above it. I tried to use the topmost form, but I can't draw it. In the case of using timer - BringToFront - it’s blinking, and when I click on it the game window is minimizing. Can anybody tell me what must I use to I saw the same working applications already, but I have no idea how to make it. Thanks beforehand. Sorry for my English. The ZMan wrote: ...Show All

• Maaloul No templates? help please

  Hi! I'm extremely new to this, and have little to no experience in these type of things. I installed Microsoft Visual C# Express Edition and registered it. I installed Microsoft XNA Game Studio Express. I installed Microsoft DirectX SDK October. Everything seems fine.... I tried to follow a tutorial on XNASpot.com. Everytime I click "New Project", I get an error. "No Visual Studio template found. See the application log in the Event Viewer for more details." Then, a blank window labeled "New Project" opens, and reads Templates: There is nothing here, no templates to select from. I've tried uninstalling, reinstalling, repairing....I cannot figure it out.

  Hi, I am creating a pong game for my first game. I am having problems detecting collisions when i am using the Draw method of the spritebatch with the rotation parameters. if i use this code everything works great: //This method is in the Ball class called from update method protected virtual void CheckCollision() { if ( this .BoundingBox.Intersects( this .Game.Player1.BoundingBox)) { _velocity.X *= -1; _direction *= -1; } else if ( this .BoundingBox.Intersects( this .Game.Player2.BoundingBox)) { _velocity.X *= -1; _rotationdirection *= -1; } } the boundingbox property is implemented as follows: public BoundingBox BoundingBox { get { return new BoundingBox ( new Vector3 (_position, 0f), new Vector3 ...Show All

• Dmitry Arefievich What is a good type of game to start with?

  So when XNA Studio Express comes out I and many other budding(a.k.a. newb) programmers will flock to our PCs to make our own games, but my question is what is the best type, or genre to begin with Would it be a good idea to start 2D, or would jumping into 3D be an option I want to start off with somthing that I can ease into and not get overwhelmed by anything too hard. Thanks for any help you more experienced programmers can give me. I am going to try to mix Space Invaders, Breakout, and Galaga. Almost any of the classics would be good. Space Invaders, Breakout, etc. Why bring networking into it You can do multiplayer on both platforms. The specific implementation is left to the reader. (but only on Windows ...Show All

• MMuffett FX Composer and DirectX Extensions for Maya (and Sas?)

  I am writing my effect files with FX Composer, it's a really helpful tool. I'd like my artists to be able to apply the various effects from within Maya 8. In another thread, someone very helpfully provided a Maya 8 version of the DirectX Extensions, but I am still encountering some difficulities. The documentation of the DirectX Extensions are extremely sparse and I can not seem to find any independant tutorials or anything on it. I'm beginning to wonder if anyone else really even uses the extensions and why or why not. In any case, I'm able to load an FX file and it shows the parameters, but I can not get any sort of binding to work. I've tried normal semantics, I tried a SasBindAddress annotation, and a few other things, but not ...Show All

• JYB Really, REALLY strange "bug" with Vector3

  For my ray tracer, I created my own Vector struct that pretty much wraps a Vector3. The thing is, I used to have just three floats; X, Y, and Z. Now I just unioned them with the Vector3. For some reason, rendering time cut down by about 15% (i.e. from 10 seconds to 8.5). I removed the Vector3 and it went back to being 10 seconds. ...Wtf Is there a hidden type constructor with Vector3 that makes it much more efficient I'm not even using any of the Vector3 methods for my transforms and such. Could anyone tell me what the hell did I stumble into I'm curious - did you find out what was going on here Vector3 doesn't do anything unusual, it's just a regular C# str ...Show All

• Rocky79 Licensing and CVS and all that good stuff

  A few questions 1. If people plan to develop in teams will they need multiple licenses to run XNA Express on multiple computers EVEN if they only plan to compile and run code on ONE Xbox360 2. Will there be a creative license under which we must publish our code, or can we choose any OpenSource license, and if so, which is "the best" 3. Will MS provide a CVS like system for teams to share there code amognst themselves, or is that the responsibilty of the of the team 4. If 3 is false, what is a good system for sharing code SECURLY over the internet(and please dont say email), are CVS or SVN good, and if so whats an easy way to set such up and do any companies offer CVS or SVN hosting 5.

• kms147 D3D10 Sprites are insane.

  I'm trying to draw a single sprite to the screen. I have a window created (640,480) and the texture loaded in properly. The sprite drawing uses the code below in a Render() function. When run, the sprite does show up but is either tiny when scaling is not applied or skewed when scaling is applied. I know i'm messing up the scaling value, i'm just confused on what the formula should be for calculating it. Right now, i'm using example code from DXUT.cpp which says the scale should be (windowx/textureWidth) and (windowy/textureHeight). This gets the sprite close, but the result is skewed. Could someone please take a look at the code below and see if you see any glaring issues Thanks. Render() { // clear the target buffer ...Show All

• pixelord Value of '\\UNC\*.exe' is not valid for 'filePath'.

  Hello all, This question is related in a way to XNA Game Studio Express, but may be out of the scope of this forum. After building and launching even a new Windows Game project an unhandled exception occurs: Value of '\\xpm-dc-01\User Data$\greg\My Documents\Visual Studio 2005\Projects\WindowsGame1\WindowsGame1\bin\x86\Debug\WindowsGame1.exe' is not valid for 'filePath'. I have gathered this is an ArgumentException thrown by the Icon.ExtractAssociatedIcon method ( http://msdn2.microsoft.com/en-us/library/system.drawing.icon.extractassociatedicon.aspx ). Clearly the value indicates a Universal Naming Convention (UNC) path. Is there a seamless way around this besides creating the project at a local location It may be important t ...Show All
