• Ayooya Streaming directly from mic to speakers using DirectSound

  Greetings, I hope this is the right forum for this question. I'm trying to write a small program that will echo input from the mic directly to the speakers. I've written a program to do this that seems like it should work but when I run it, no sound. I was wondering if there was anything that I'm doing wrong or not doing or whatever Its written in C# using VC# Express 2005. Thanks, FM Program source: using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Text; using System.Windows.Forms; using System.Threading; using Microsoft.DirectX.DirectSound; namespace Echo { public partial class Echo : Form { private Capture _captureDevice; private CaptureBuffer ...Show All

• pandasar What does creators club include right now?

  I'm a little puzzled about what the creators club actually includes, I've checked the FAQs and can't really find an answer. I have however managed to find the following: "The XNA Creators Club is available on Xbox LiveR Marketplace for $49 (U.S.) for a four-month subscription, or $99 (U.S.) for an annual subscription. Both subscriptions provide aspiring game developers with access to thousands of game assets from Microsoft and key partners such as Turbo Squid Inc., as well as white papers, specialized starter kits, samples and technical product support to help turn Your World, Your Game into a reality." I signed up for a year because it sounds like quite a good package, however there seems to be no information provided on ...Show All

• SCRunner I can’t see my colors on the cube

  Hello everybody. I’m trying to get started with DX. I’m trying to render a simple cube with 36 Vertices (12 triangles). The problem is that the cube is black and if I try to set the color for each vertex nothing happens. I’m getting crazy because I can not find the problem. I set the FVF and disabled CULLMODE. Lights are disabled and I’m using DrawPrimitiveUP to render the cube. What could be the problem The sample code from the tutorial I’m working on works well. But my code looks almost similar (as I can see). I hope that someone can help me. P.S: My Vertextype includes a D3DXVECTOR3 vector and a D3DCOLOR variable defined in a structure. You need to Set your ColorOP to SELECTARG ...Show All

• MShetty How to Disable Smoothing when scaling texture2d ?

  Hi, To start with xna, i've decided to make a simple chip8 emulator. The original window size is 64x32, so once the codes are interpreted and the screen is drawn in my chip8 class i call SetData() to draw everything on a single texture2d. The problem is that when i use the Scaling parameter all the pixels are smoothed... In another program this could be helpfull, but in this case it gives really ugly ... So hwo can i disable smoothing pixels when scaling a texture2d or, is there another way to render my screen (it's an int array of size 64*32) Thank you . Hi all, Is this supposed to still be working I'm trying to disable filtering for scaled Texture2D stuff and none of these solutions is working for me. ...Show All

• MicahN DreamBuildPlay is up!!!

  Now go register!!   Actual contest details to come the week of Feb 5th Plese, Someone at Microsoft.... the drembuildplay site, even though the competition should be global, does not allow non-US people to register.

• Arkady Frenkel IDE problem

  I downloaded XNA today from microsoft after installing the VS 2005 express edition. I then watched a tutorial on how to develop pong and noticed a difference in my IDE. when i go to create a new project, i do not have the option to create "Game(XNA)". Mine says: "Game". the text below the project type window says it's an XNA 1.0 game so i clicked it. I then noticed my default game1.cs class has no designer to it. There is supposed to be an expand option on the class so i can set properties such as height, width, etc. My game1.cs is simply a class with no way to view it in design time. Has anyone else experienced this Thanks. XNA Studio Projects don't support Form Designers, so you'll ...Show All

• zybernau Dream Build Play Contest Question - Using languages other than C#

  I've managed to use Chrome ( www.remobjects.com ) to create some small XNA demos that use the content from SpaceWars. The rules do not mention whether non C# langauges are allowed to enter the contest. Since there are several .NET 2.0 compatible compilers out there shouldn't this contest allow these entries as well as they can use both the Windows and XBox 360 XNA assemblies. Just to clarify, I have Visual C# Express and Game Studio Express installed on my machine, but am using Chrome via Visual Studion 2005 to write and compile my XNA demos and the plan is to use that combination to write future XNA games and contest entries. Could someone from the XNA contest team please clarify your position on the use of non C# languages for the Dream ...Show All

• DVAz 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

• FS2K System.Reflection.Assembly

  I'm finally getting around to porting what I had written during beta 1 over to the RTM. I'm thinking about building my engine in a modular fashion so that I can issue pluggins to extend its abilities easily. The XNA documentation lists System.Reflection.Assembly as an supported object on the 360. Is this true, and how does the FromFrom, etc methods work on the 360. Obviously the file paths would not be the same as Windows. I do not have an Creators Club Membership to verify how this works on the 360, but would like to know so that I could potentially plan for such functionality (If possible). A quick search on the forums did not reveal any prior posts on this topic. Thanks. System.Reflection.Assembly.LoadFrom can take ...Show All

• alienated Is there an easy way to generate a random color?

  I was trying to generate a random color to be passed into the Sprite Batch Draw function to put a tint on the sprite being drawn. mSpriteBatch.Draw(mBackground, new Rectangle (0, 0, 1024, 768), mRandomColor); However, there doesn't appear to be any way to create a new color from RGB values for the XNA frameworks Color object. I had thought that I would be able to do something similar to how you would create a new color when using the System.Drawing dll. Color mRandomColor= Color.FromArgb ( ( random.Next ( 0 , 255 ) ) , ( random.Next ( 0 , 255 ) ) , ( random.Next ( 0 , 255 ) ) ) ; Is there an easy way that I'm just overlooking to achieve that same effect Lol, now wonder you thought my question was about get ...Show All

• Yuki Chen How do I find the collision normal of two rectangles?

  If anyone has any idea, please let me know. I'm not entirely sure how to begin on this one. I've got collision detection down, but have no idea how to find the normal. The normal of an object is usually derived from the dot product of the verticies you are checking for collision against. This is usually done more easily through the use of bounding boxes or bounding frustrums. Try looking on http://gpwiki.org and www.gamedev.net both are very useful for finding out about such things. Also have a look at the Farseer Physics engine on codeplex, which has a lot of collision code and should help. Hope this helps Darkside (P.S I'm going completely from memory here as I couldn't find the article I read this from by the wa ...Show All

• Alexander Stoyan Visual Studio 2005 Pro & XNA Game Studio Express {Installation Problem...Need Help}

  I have installed Visual Studio 2005 Professional Edition with MS Visual C# 2005 and MS Visual Web Developer but when i try to install XNA Game Studio Express (Beta), a message box pops up saying that setup requires Visual C# 2005 Express Edition, i already have VS 2005 Pro Edition with Visual C# so whats the problem.... The biggest downer for me in regards to the Express flavor of Visual Studio is that you don't have integrated source control support. That's incorrect: VS Pro and Express are separate products and can be installed side by side without any problem. So downloading and installing C# Express is a must, is there no other way around ...Show All

• Rraj Sprite Rotation using Left Thumbstick?

  Help ! Ok, so I am a noob when it comes to game dev and C# programming. But, Im wrapping my head around things pretty steadily. Problem Ive run into is that I want to rotate a sprite (the main player character) based on the circular motion of the Left Thumbstick. Basically, Im trying my "learning experience" type game to be a clone of Geometry Wars (seems like a pretty simple concept for a game, so why not try starting with that). Ive got things going pretty well, and am now to the point of adding "better" features. One of which is the most obvious, making the player sprite rotate and "point" in the direction that it is flying. Ive come up with a bit of a hack to get it working, but it only supports ...Show All

• Eileen Ewen loading large image using DirectX

  Hi all. First of all, I'm new to DirectX. I'm trying to load an image into a PictureBox component (C#) using DirectX. The problem is that I'm working with large pictures (for ex. 4021x3123) and can't use the Windows GDI, because the picture takes a lot of memory and it flickers when I move the scrollbars. That's why I was thinking of using DirectX. I've linked the DirectX Device with the PictureBox: Device device = new Device(0, DeviceType.Hardware, pictureBox1, CreateFlags.SoftwareVertexProcessing, presentParams); The problem is that I don't know how to load the image as a backgroud image using DirectX (i need to do some drawing on it after it loads). Is there a way to load it and prevent the flickering when i move the Pi ...Show All
