    - Multi threading in a game (using XNA) It is more like separating code. The keyboard / mouse is just a start. Using gamepad is what comes next. And if I want to push it to an XBox, I might have up to 4 Gamepad to manage. So, instead of having the video renderer manage keyboard inputs and some checkings about those inputs directly I was thinking of running a thread to manage a device that would communicate with the renderer. And since the treatment required by the input might be heavy, splitting input management, and video rendering seemed like a pretty good idea. Now, maybe, that is not how I should do it, but I do not really see any other way. Also, splitting input management and video rendering in 2 threads is interesting for multicore CPUs. Any input is interesting to have regarding this. Regards, Chryso Tag: Joysticks with XNA

    - GC Related Crash? Running into a really odd bug here. It seems that some parts of the XNA framework stop working right after a GC collection. I've found two cases: Instances of ShaderConstant break after a collection on PC. By break, I mean that the first SetValue following a collection throws an AccesViolationException. I've thrown a simple repro case at the bottom of this post that calls GC.Collect, but note that the same thing happens if you allocate objects each frame and leave them around for the GC to collect at some point (it just takes a while). On the XBOX I get a different crash: I get an InternalDriverException (or whatever it's called - typing from memory here) on the first DrawUserIndexedPrimitives call following a collection (I believe I used to see a similar bug in VertexBuffer.SetData before I switched to user primitives). This doesn't really seem like a bug that should have gotten past QA (I honestly can't see all of XNA history up until now go by without a single garbage collection), so I'm guessing I did something wrong when I installed/downloaded the launcher onto my XBOX - can anyone give me a hint Thanks, Phill #region Using Statements using System; using System .

    - missing Direct3D device??? No, Pixel Shaders are required because XNA uses them as a foundation. However, why are you so worried Graphic Cards that support Pixel Shaders (3.0) are only like $50.00. Here is one I found on amazon, but every card is around this price, and PCIe cards are even cheaper. http://www.amazon.com/eVGA-GeForce-6200-256MB-256-A8-N341-L2/dp/B000EPYLII/sr=8-4/qid=1168604964/ref=pd_bbs_4/105-2099284-0242863 ie=UTF8&s=electronics EDIT: Btw, Pixel Shaders 3.0 is the latest version of Pixel Shaders as far as I know.

    - Texturing problem Your builder code looks ok to me. I think this would be a good time to bring out PIX for Windows. Get a capture of one frame of your game, and debug inside the rendering of your mesh. This will let you examine exactly what was in the texture while rendering, what values were read into the vertex shader, and what the vertex shader outputs were: that should make it easy to see where along the line the data is going wrong.

    - How to apply an effect to a mesh rendering? I'm using the Model object that comes with the XNA framework and have a loaded mesh from 3dsmax rendering on the screen. My question is, how can I apply a pixel shaders to materials on the mesh when rendering For example, the engine of the craft I am rendering is a separate material and I want to apply a glow shader just to the engine. I know which sub-material it is but don't know how to set the pixel shader to be used in the mesh.Draw() function Any help would be appreicated. Thanks! Tag: Joysticks with XNA

    - The Unofficial "Hooray I'm Done With my DBP Game" Thread Well, I've just finished uploading Space Fortress - a remake of Space Zap! from the early 80's. I've still got a list of things I wanted to add, but that I ran out of time for. The quote about adding people to a late project will make it later is very true. I'd started with a team size of three - Me, my wife, and my 3.5 year old playtester, Katrina. Feb 27th we added a new team member - Naomi. I'm just happy my wife is so supportive of my attempts to get a game built. Cheers to all, and the best of luck to one and all. Dan Lingman nogotogames.com Tag: Joysticks with XNA

    - Generating Grid With Loops I'm trying to create a grid for my program, but I can't get it to work. Right now it just draws real long lines instead of a nice grid. I understand the buffers, but I feel like I'm calculating either the vertices or indices incorrectly. Any ideas int numVerts = (size * 2) * (size * 2); int numVertsRoot = (size * 2); verts = new VertexPositionColor[numVerts]; int numIndices = numVerts * 2; indices = new short[numIndices]; int index = 0; for (int i = 0; i < numVertsRoot; i++) { for (int j = 0; j < numVertsRoot; j++) { verts[i * numVertsRoot + j] = new VertexPositionColor( new Vector3(i - size, 0, j - size), Color.White ); if (j > 0) { indices[index++] = (short)(i * numVertsRoot + j - 1); indices[index++] = (short)(i * numVertsRoot + j); } } } Tag: Joysticks with XNA

    - Global lighting This might seem silly but here goes.. is there a way to set the default lighting for all objects This is what im doing now..(taken after spacewars) Matrix m_view = Matrix.CreateLookAt(cameraPosition, Vector3.Zero, Vector3.Up); Matrix m_proj = Matrix.CreatePerspectiveFieldOfView(MathHelper.ToRadians(45.0f), aspectRatio, 1.0f, 20000.0f); for (int i = 1; i < MAX_MODELS; i++) { foreach (ModelMesh mesh in Enemy .C_Model_m.Meshes) { //This is where the mesh orientation is set, as well as our camera and projection foreach (BasicEffect effect in mesh.Effects) { effect.EnableDefaultLighting(); //effect.LightingEnabled = false; effect.World = Enemy .C_Actor_m; effect.View = m_view; effect.Projection = m_proj; } //Draw the mesh, will use the effects set above. mesh.Draw(); } } When i do this my Frame rate takes a big hit... I narrowed the problem down to the line of code effect.EnableDefaultLighting();....... Its not so much the lighting, because if i shut the lighting off after this call i still get a crazy slow FPS. Is there anyway i can just EnableDefault lighting through out my game... so its not enableing it for every effect in every mesh of every model Thanks, -Wes Tag: Joysticks with XNA

    - Terrain & Terrain-Physics (intersection, dynamic slicing) Hi, at the moment i am wondering how to deal correctly with a terrain in XNA. For now i just have a static terrain model loaded from file. So i have an object (a buggy for example) and want to get some physics on it, therefore i need to check for collision with the underlying terrain. The collision with the buggy could be done with a boundingbox, but the terrain needs to be checked per face (3 vertices triangle) i think. But i cant find a way to check this. I think iteration throught all faces of the terrain would take to long for all objects in the world. How do other developers solve this problem So if I do it this way i will always need to calculate every object in the world each frame, no mather if its visible or not, is this the correct way I really get crazy about this whole scenario and don't know what ways are right and wrong Also i am confused about slicing of the terrain, a big game world with hundret-thousands of vertices needs a slicing algorithm, but do i automaticly need a dynamic terrain based on a vertex array in XNA How else to slice an existing model Hopefully someone can help me out here Cu Thunder2002 Tag: Joysticks with XNA

    - texture moving on a vertext shader Hello Noobie question here for you. I'm copying the example from the help files in GSE (the example titled: How to create custom texture effects), and have managed to successfully port the cube into my game world (which is a hacked version of the top-down spaceship example that is right at the begining of the help files). I have changed the spaceship example to always keep the spaceship in the middle of the screen, so I can fly around asteroids that I have put into the game, and I've also managed to set a boundary to stop the spaceship flying off in one direction for ever. Now I want to adapt the custom texture effects code to stay in one place while my spaceship flies around it. I did this by updating the custom texture effect "world-view-projection" data with the view of the spaceship during the draw() function. This makes the cube stay in one place, but the texture on the cube moves with the spaceship. What I think is happening is that the tex2D part of the code is using the spaceship view to position the texture on the cube. So when the spaceship moves the texture moves around on the cube. Any idea how I can edit the custom texture "fx" file to seperate cube coords from texture coords Many thanks, SuperArmySoldier Here is the ReallySimpleTexture.fx code... uniform extern float4x4 WorldViewProj : WORLDVIEWPROJECTION; uniform extern texture UserTexture; struct VS_OUTPUT { float4 position : POSITION; float4 textureCoordinate : TEXCOORD0; }; sampler textureSampler = sampler_state { Texture = <UserTexture>; mipfilter = LINEAR; }; VS_OUTPUT Transform( float4 Position : POSITION, float4 TextureCoordinate : TEXCOORD0 ) { VS_OUTPUT Out = (VS_OUTPUT)0; Out.position = mul(Position, WorldViewProj); Out.textureCoordinate = TextureCoordinate; return Out; } float4 ApplyTexture(VS_OUTPUT vsout) : COLOR { return tex2D(textureSampler, vsout.textureCoordinate).rgba; } technique TransformAndTexture { pass P0 { vertexShader = compile vs_2_0 Transform(); pixelShader = compile ps_2_0 ApplyTexture(); } } Tag: Joysticks with XNA

    - Content Pipeline Alex: I would not use the MsBuild approach for what you describe, I would add the file to my project as well as all the textures and create a custom processor to write out the file names. Or your custom processor could process each file and write them as external references, meaning you would only have to add the 1 file describing all assets to your project. I am taking this approach for some of my objects that have metadata and assets attached with them. Tag: Joysticks with XNA

Before I start I already know that XNA has no joystick input support - but I'm using an xbox 360 styled joystick input with force feedback (so its exactly like the xbox 360 control) this is it:
http://www.powerwave.com.au/index.php evnF=productImage&format=&title=Powerwave%20360%20Shape%20Controller%20-%20Carbon&id=2.195326&acode=APCPW2C3C
And I want to know if anyone can help me get it working so when I debug a game in XNA I can use this controller I've bought instead of my keyboard.

Or at least if anyone knows any software I can use that converts joystick input to keyboard so I can map the triggers on the controller to the keys that XNA uses.

Thankyou for your time.

You probably can use DirectInput to handle it and pass it to XNA if you're only interested in the PC side of XNA.
