• RayClark096 Weird lightning on custom mesh

  Hello everyone, I've been playing around with XNA for a while now, and I can't seem to get the lightning right on a mesh i'm dynamically creating. I've created a simple GameComponent that initializes a VertexBuffer and an IndexBuffer in the LoadGraphicsContent method. The Draw method uses a BasicEffect (with default lightning enabled) to draw the vertices using the TriangleList primitive. I've used the DrawIndexedPrimitives method for this. The lightning on the mesh is totally wrong, i've uploaded a screenshot at the following location to see the effect here: http://www.fegelein.com/projects/xna_fegelein/WeirdLightningTorus.png Also, you can download the complete sourcecode here: http://www.fegelein.com/projects/xna_fege ...Show All

• TCSC Game Studio Installation Error (on windows vista ultimate)

  I'm having trouble installing XNA Game Studio Express. I just upgraded my computer to Windows Vista Ultimate from Windows XP Pro and after I reinstalled Visual C# Express and then tried to install XNA Game Studio Express it gives me an error saying: "Microsoft Visual C# 2005 Express Edition has stopped working" then below that it says: "A problem caused the program to stop operating correctly. Windows will close the program and notify you if a solution is available." and it gives me one option, "Close Program." THEN when I click close program it gives another error message saying: "This installation package is corrupt or damaged." I don't know what to do besides re-install XNA from Microsoft. I hope ...Show All

• Gravy using CatMullRom

  Hi everybody, Can anyone help me using CatMullRom function,i wanna draw a curve through difining points by mouse,so how can i do that either using this function or another way Once you have the points defined, you can call the CatmullRom function to interpolate between them. But it won't help you create these points of course. You'd probably want to take a look at the code for some 2D graphing library/program that can draw curves with CatmullRom (I'm not aware of any that uses CatmullRom though... sorry). Here's a place where there's an explaination and example code http://www.mvps.org/directx/articles/catmull/ ...Show All

• Tryin2Bgood State changes made by ID3DXLine?

  I'm using Direct3D 9 to draw an layered interface with extensive alpha blending. To draw antialiased lines I use the ID3DXLine interface, which works fine to me. Problem is that if I call ->SetAntialias(true) on my line interface, alphablending stops working for any sprites drawn with ID3DXSprite afterwards. But If I draw a line without antialiasing it starts working again. I'm no expert on 3D and D3D, but I cannot seem to detect any texture state changes or render state changes made by the interface, and I don't know what to fix I can get around the problem by drawing the line twice, one time with antialiasing and one time without (with zero alpha) but I'd rather have a proper solution. I don't have this problem on all computers, ie ...Show All

• GlitchEnzo XNA on Original Xbox?

  Back when XNA was first announced at GDC 2004 it was said that XNA would be a unifying environment for both original Xbox(and future versions), PC and mobile devices. With the XNA framework now available for the Xbox 360 are there any plans for supporting the original Xbox I know there are about to be 10 million Xbox 360 consoles shipped by the end of this year, but as of last May Microsoft said they had shipped at least 24 million Xbox consoles worldwide. It seems like it would be a good idea to also target that larger audience that has the original Xbox console, no BTW, I did read the FAQ and found the following entries: Q: Is the XNA Framework available on non-Microsoft platforms A: At this time, the XNA Framework is only avai ...Show All

• Erik BN 2D GUI with controls?

  Hi and hello. :) Is there any XNA game engine that provide components like windows forms one (textbox, checkbox etc.) Or maybe it's built-in in XMA There's also this one . Looks good! :) Thanks. It is not built into XNA. However I have found two projects that provide this capability: http://jsedlak.org/xna5d http://www.nuclex.org/news/2007/01/14/ceguisharp I haven't tested either of them. ...Show All

• Mgrondin345 Saving model to .x file

  Because XNA doesn't yet support mesh saving functionality, I'm using MDX to save a model to a .x file. This is the code I'm using:             meshTerrain = new Mesh((WIDTH - 1) * (HEIGHT - 1) * 2, WIDTH * HEIGHT, MeshFlags.Managed, CustomVertex.PositionTextured.Format, device);             meshTerrain.SetVertexBufferData(vertices, LockFlags.None);             meshTerrain.SetIndexBufferData(indices, LockFlags.None);             int[] adjac = new int[meshTerrain.NumberFaces * 3];        ...Show All

• levitymn simple projectile motion physics??

  im pretty new to gamedev, so simulating physics is new to me too. i know the projectile motion formulas, im just having trouble applying them. is there any "tutorial" on projectile motion physics for XNA basically, someone suggested to do "scorched earth". im trying to get the hang of just some simple projectile before i apply it to a game. i know i should basically have to just enter the initial velocity vector and the angle. then have it passed to a function that gets the initial x velocity, and initial y velocity. also, im assuming that whatever i get for y-velocity should be negative as "up" is negative in the XNA graphics. then, after each update, it should find the current change in position for x and ...Show All

• Wesolek xna launcher problems after update

  After the most recent Xbox 360 dashboard update, the XNA Launcher cannot find my subscription upon startup. After it cannot find the subscription it forces me to quit the launcher, I'm back at the xbox live blade signed on with my profile but disconnected from xbox live (I was connected and confirmed my subscription in marketplace before starting the XNA Launcher). I suspect it may be related to another odd behavior that happened after the update, when I sign on to my profile after the console boots up I have to now manually connect to xbox live where as it used to just sign on with my profile. If I sign out and sign back on it connects automatically. So when XNA Launcher starts, does it restart the console Does it expect the profile ...Show All

• kbalusu dxdiag under Direct3D 10?

  Hi all, is there anything like DirectX Diagnostic Tool (dxdiag) for Windows Vista x64 I wanted to do some performace testing on my ATI 19000XTX. I want to check if the low FPS on some D3D 9 games is because of D3D 9 emulation or driver issue. My guess is that the driver works fine, but the software is not optimised to D3D 10 & Win Vista 64bit. Is there any workaround to speed up non "D3D 10 & Win Vista 64bit" software Regards, JoeBlk The windows key merely brings up the start menu. So if you do not have a windows key then just bring the start menu up in another way. Anyone who want to start the DirectX-Diagnostic-Tool (dxdiag) in Win. Vista x64, do this steps in Win.

• KVdS how to add directx reference to project?

  I'm using VS 2005, .NET v.2 and i have installed Microsoft DirectX 9.0 SDK (C#).

There is no directX references available in add reference window, i tried browse but nor C:\WINDOWS\assembly\ there is no dll's, in C:\WINDOWS\Microsoft.NET\Managed DirectX\v4.09.00.0900 there are only xml files....

• BobTheBuild 3d Samples ?

  I'm not interested in 2d, so I'm looking for 3d samples but can't find any. Is it because the content pipeline thingy is not finished yet Or are there 3d sample programs When is the ETA for the next release that includes the content pipeline December 2006, I think. "Holiday 2006" for final release is the only announced future date. Content pipeline builds are not publically availalbe. And yes the reason there are so few tutorials is becuase getting 3d content in is very hard and any work that you do will likely be made worthless when it releases. Note that the spacewar sample does show 3d, even though it it played in a 2d plane. However a lot of that code will be changing with the content ...Show All

• Angry Coder Adding a simple shader to render a ModelMesh

  I'm trying to figure out how to render with a shader instead of the default render style. I have quite a bit of experience with CG shaders from NVidia so I know the concepts, but when I'm trying to use XNA's HLSL, nothing is showing up. Here's what I'm doing. Any ideas what's wrong I'd like to note that I HAVE been following the help files, but the help files go into DrawIndexedPrimitive rather than mesh.Draw(), which I know isn't required and only helps to confuse me with the idea of applying a shader effect. On Load: shaderEffect = content.Load<Effect>("Content\\Shaders\\simple"); shaderEffect.CurrentTechnique = shaderEffect.Techniques["TransformTechnique"]; effectParam_wvp = shaderEffect.Pa ...Show All
