I'm utilising some 2d / 3d tracking data (provided by pfHoe) to help integrate some 3d models into the playback of some 2d video. Things are working.... okay... but there's still some visible 'slipping' of the models against the video background and I suspect this is may be because the XNA CreatePerspective helper method isn't taking in...
i want to animate 3d model in xna programmatically ,i tried to transform bones but nothing to happen only the whole model transform not individual bones as i want i read the 3d model by basic model processor so how i do this ? and is there any need to extended model processor like skinnedModelSample please explain the steps ...
I'm playing with XNA. When I click the left mouse button, I record the X,Y co-ordinates. Keeping the mouse button held down, moving the mouse draws a line from this origin to the current mouse position. I've offset this into the middle of the window. Now, what I'd like to do is restrict the mouse cursor to within a circle (with a radius...
I'm trying to apply fog of war to areas on the screen not currently visible to the player. I do this by rendering the game content in one RenderTarget and the the fog of war into another, and then I merge them with an effect file that takes the color from the game RenderTarget and the alpha from the fog of war render target. The FOW Rend...
In HLSL, is there any way to limit the number of constant registers that the compiler uses? Specifically, if I have something like: float4 foobar[300]; In a vs_2_0 vertex shader, the compiler will merrily generate the effect with more than 256 constant registers. But a 2.0 vertex shader is only guaranteed to have access to 256 consta...
I have a vertex shader (2.0) doing some instancing - each vertex specifies an index into an array. If I have an array like this: float instanceData[100]; The compiler allocates it 100 constant registers. Each constant register is a float4, so it's allocating 4 times as much space as is needed. I need a way to make it allocate just 2...
Hello, I realise there are numerous questions on here asking about choosing between XNA and SlimDX, but these all relate to game programming. A little background: I have an application that renders scenes from XML descriptions. Currently I am using WPF 3D and this mostly works, except that WPF has no way to render scenes offscreen (i.e....
I've looked around a lot and the only methods I've found for creating a Texture2D from a Bitmap are: using (MemoryStream s = new MemoryStream()) { bmp.Save(s, System.Drawing.Imaging.ImageFormat.Png); s.Seek(0, SeekOrigin.Begin); Texture2D tx = Texture2D.FromFile(device, s); } and Texture2D tx = new Texture2D(device, bmp.Wi...
I am writing a map editing program for a 2D game using XNA. To create a Texture2D for all of the tiles that a map requires takes too long. Are there any alternatives to using textures for drawing with XNA? I attempted to create just one texture per tile set instead of a texture for every tile in a tile set, but there is a limit to the...
Hi folks! I have a WinForms application that uses XNA to animate 3D models in a control. The app have been doing just fine for months but recently I've started to experience periodic pauses in the animation. Setting out to investigate what is going on I have established these facts: It happens on my machine only, other machines works ...
I've been looking for a decent network library for C#. It is going to be used with XNA 3.1, and .NET Framework 3.5. The multi-player style is going to be Server and Client. Currently I have been looking into Lidgren Library Network, but it seems outdated. Anyone got some good suggestions for a good network library. It should be able to ...
Hey guys, I've got an XNA project that will be drawing several objects on the screen. I would like the user to be able to interact with those items. So I'm trying to build a method that checks to see which object the mouse is over, out of those which is the top most, and then fire an OnClick event for that object. Checking for the thin...
Hello. I'm currently making a game in XNA4 for Windows phone 7, and I'd like to know if it were possible to get the event of the return button, or even the windows button that are basically present on the phone's interface. If so, how can i do that? thanks, KiTe ...
Okay, so this is sort of a hack...but it may have to be. I'm writing an app in XNA, which from my research into this problem apparently doesn't support XML version 1.1. I'm reading in the contents of an ePub document, and one of the newer books contains its content directory as a version 1.1 XML document. This causes my program to crash....
I've had a quick google, but can't find anything obvious that answers the question. What are the best games developed using XNA for PC? Any flagship games, original games.. etc? Obviously 'best' is pretty subjective, but I'm sure they'll be a common consensus on some of the good ones. (I don't own an XBox (if that matters...)) ...
Hey everyone, Just wondering - throwing ideas in my head - about starting a new XNA project for the 360. I would like it to be retro-old school, and emulating scanlines and color palettes and such. As part of this idea, what I would ideally like to do is manually draw each and every pixel of the screen. So, worst-case scenario I would...
Everytime I load my model into XNA, I can usually see it far off in the distance. When I change some parameters and make it zoom up close, 10/10 times it's rotated funny and I'm set with the task of rotating it. Is there any easy way to do it except by experimenting? Or am I exporting it wrong (using Blender)? Is there any value I should...
can anyone provide me more information about XNA Development? for what usages it is good for? ...
I'm working on a 2D Platform game, and I was wondering what's the best (performance-wise) way to implement Surface (Collision) Detection. So far I'm thinking of constructing a list of level objects constructed of a list of lines, and I draw tiles along the lines. I'm thinking every object holds the ID of the surface that he walks on...
Hi, I am currently working on a game in C# Xna, which works with (X,Y,Z) coordinates. Each unit, contains some information about what is placed at that position, etc dirt, rock or nothing. But I am pretty new into 3D game development, and I need some ideas for 3D map generation algorithms. I thought of interpolation or perlin noise, but...
