• anshuman_atri Losing Background Surface

  Hiya, I'm working on a simple 2d shooter game in VS 2003 using managed DX. Problem: my backgrounds (LPDIRECT3DSURFACE9) start disappearing after x levels Computer 1 has a Radeon Mobility 7500 that has 32 meg of VRAM and starts losing backgrounds after 7 levels. Computer 2 has an integrated graphics card with 64 meg of VRAM and starts losing backgrounds after 11 levels. So it seems that I'm not releasing somthing properly but I have thoroughly checked this. The way it works is as follows: 1. Load Menu and associated textures and surfaces 2. User clicks 'play' and all Menu textures and surfaces are released 3. The Game is initialized loading all textures and surfaces from scripts 4. player completes ...Show All

• mehran farshadmehr EffecMaterialContent behavior in a custom model processor

  Hi, I'm writting a custom model processor and I have some questions about it, if anyone can help me I should be grateful.  I'm using MeshBuilder to build my mesh, geometry, texture channels, normals... and this works perfectly. I'm putting my textures with 'EffectMaterialContent myMaterial = new EffectMaterialContent(); myMaterial.Textures.Add(keyname, new ExternalReference<TextureContent>("mytexture"))' method. a) I build my asset model in my game project and the texture is named "mytexture~0" and I don't understand why appear that sufix "~0"  if I don't have other texture with this name in my project. b) I would like to know if I must load my model’s texture with 'myCo ...Show All

• Nitin Sharma22 Applying custom effects to an imported model

  Hi everybody! I'm playing around with my shiny new Beta2, and I'm loving it. :) I've hit a bit of a stumbling block, though: I have a .x model that I've imported, which was pretty elementary.... What I've not been able to do is find the proper methodology for associating a custom, imported effect with the meshes in my model. How exactly do I do that And what if I want different material effects applied to different meshes in the model Thanks, and I appreciate the help! I have the same problem. And there is no way to add custom effect to entire mesh, only to a parts of mesh. for me it doesnt seems to work I did what you told , here is my loop : foreach ( Mo ...Show All

• EB78 Problems on resize

  Hi, I’m the coordinator of Jad Engine, a MDX 1.1 open source 3d engine. We have had one bug around for several months that we are unable to solve related to resizing the device. At the start, we used SetAutoDepthStencil = true when creating the device, and there was nor problems with the resize. But nowadays we do it manually and SetAutoDepthStencil is false. But when we reset the device, the D3D debug tells us that one surface has not being liberated. That surface is the DepthStencil we just created, because if we don’t create it, the reset works. The Microsoft.DirectX.Direct3D.Device.IsUsingEventHandlers is set to false as we create ourselves the VertexBuffers in DEFAULT mode and that’s the only way that they don’t give us an error on th ...Show All

• anomolous VertexBuffers and IndexBuffers

  Hi All! I am very new to the XNA framework, I have experience with DirectX and thought that XNA would be an easy challenge. I was wrong - I obviously lack something here. I have been able to create a VertexBuffer with several (repeated) vertices and put it on the screen. Although I have not yet been able to do perspective or lighting*, this is not my main concern. I wish to use an IndexBuffer object to store the list of vertices in the order that I want them rendered. I cannot figure out the method of doing this. I realise there are other ways of loading meshes, but this is the way I want to do it. I am reading a .off file (I don't want to convert it to a .x file -- I think there are tools out there, but no no no!!!), but currently I am j ...Show All

• Gregoryew Multiplayer & C# XNA

  Hi, I've downloaded and installed the XNA Game Studio Express (beta) and then gone through the tutorials. All is working great and I have a couple of simple stand alone 2D games working. I would now like to try and make a simple 2D or 3D XNA game with multiplayer capability in mind. Now I have searched through the forum and FAQs and found that multiplayer is not CURRENTLY available for the Xbox. This is fine as I'm new to all this and I’d like to develop my first multiplayer game as more of a learning experience than anything else so am happy to just start on Windows XP. For multiplayer on Windows XP one of your posts suggests using System.net but doesn’t go into any other detail or point to a site ...Show All

• Zachovich Compiling Errors in FX?

  I came to an error when compiling. And the error is an internal error in the fx file.The error description is like this: "d:\Program Files\NVIDIA Corporation\SDK 9.5\MEDIA\programs\HLSL_VideoFilter\VideoFilter.fx(618,2): internal error: invalid access of unbound variable" And the error code lies here: texColor0 = tex2D( YUVSampler, VSOUT.TexCoord0 ); Later I compiled .fx file in FX composer, it's just ok. Can anyone tell me where this internal error comes I am using Nvidia SDK 9.5, it should be fine because the project I was compiling was its own sample. It's the videofilter sample from the sample browser. All I have done is just following the "how to build" within the project. It's ...Show All

  How easy it to make GTA-style game with XNA Game Studio Express.. I haven't downloaded it yet so I'm thinking of doing it.. :) Is it possible to make that kind of game Thanks, Timo Oh sorry!

• WIreD 0x90 Levels with XNA

  Hello, I'm looking to make my levels in 3D Studio Max however I have no idea how to get it working as a level within XNA. For example if I made a Office Building with 3 Floors a lobby, middle floor and an upper floor how would I go about making movement with a camrea when you go up stairs for example Or if you run into a wall so you don't go through, I'm looking to work a 1st person game with nothing but an office building and movement to learn from. Any help would be great! Jim has answered your question already pointing at the XNA Help. All you need is to implement collisions detection and the free camera.So you have to assign the bounding boxes/spheres to  your geometry,main hero ...Show All

  Is there an easy way to get a standard ascii (ok, unicode, whatever..) character from the XNA keyboard input   I'm looking to type some normal text in - and need to be able to support different keyboard layouts(particularly UK/US) and preferably international characters as well. I was really trying to avoid hard coding something like that, simply because I don't have a complete set of international keymaps - that code looks to support only the US keyboard and ignores international characters. Hmm, wonder if I could load the keyboard details into an array holding those keycodes, now, how to do that.. The keyboard search goes on. It sounds so simple.. ...Show All

  I've imported a semi-transparent PNG to use for a sprite but the alpha channel isn't taken into account. It just renders as a fully opaque texture.

I tried that but it just lightened the blocks rather than letting the background shine through like my original problem.
