• byronfromwesleyan 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 Here's a couple of useful examples: http://www.threesixbox.com/project/ id=e07a8da6a6 http://www.threesixbox.com/project/ id=2a9221cf3d For this one you have to roll back your clock's date to compile with Aug DX SDK: http://www.codeplex.com/Wiki/View.aspx ProjectName=eXperience good luck protovision December 2006, I think.

• rod 001 Need help with 2D sprite animation using C++

  So far, my program is very simple, I have only drawn a sprite using a texture interface and moving it in the my game loop with 4 keyboard keys: W, A, S &D.  But I'm already getting lag and inconsistent animation(just movement in this case) rate: 1.  If I try to move the sprite in the one direction, it will start out very slow, and then speeds up to a constant pace.  Then if I let go of that key and hit anther key to head towards the other direction it will again start at a slow pace in the first 2 seconds then gets faster afterwards.  2.  At different times, the sprite will move in the same direction at different speed: sometimes faster and a few times slower.  Since I increase/de ...Show All

• DQM Visual Studio 2005 Pro and XNA

  For whatever reason, I can't get XNA of any flavor to run with Visual Studio 2005 Professional. (A legal copy, before you ask.) I'm told when I try to install XNA that I need Express Edition. Surely XNA won't lock me out because I have a better program than the required edition Anyone If you uninstall C# Express and use VS Pro instead, you won't have the project templates (no big deal) and you won't be able to use the content pipeline (big deal). Also, if you care about developing for and deploying to XBox, you won't be able to do that either. As others have stated, you can install both with no problems. Just use C# Express for your XNA development and VS Pro for anything else. It's not that big a deal. ...Show All

• Averied Any scripting support?

  I haven't found any info on scripting support in XNA. And the disccussion on supported languages seems to mean only C# is usable with XNA. So we cannot incorporate any script engine What about the DynamicMethod class Just found that info. :( Given that the XBox 360 version of the framework is based off the Compact Framework, will Assembly.LoadFrom(String) also be available, allowing us to precompile our scripts as part of a pre-build step Why not just use C# for your scripting (assuming the XNA Framework allows it). See www.gamedev.net/community/forums/topic.asp topic_id=264462. As written in another thread the necessary methods are currently not supported ...Show All

• cmfairbank 2 ContentTypeReaders with the same return type.

  I implemented a scenegraph and have several ContentProcessors, ContentReadersWriters and ContentTypeReaders. Because all the objects have the same base class, i want to have all ContentTypeReaders to use the same type, but i get an error. Is this not possible You might be able to create a hierarchy of ContentTypeReaders that inherit from each other, but you'd end up having a 1-1 correspondence between each class, each reader and each writer. This is an interesting idea that might end up saving you time with some thought. " This is fairly obvious, if you think about it: Which reader would Load<SomeType> call if it had to choose between multiple " I believe that is determined by the ContentTy ...Show All

• Dirk Haest XNA Basics

  I am currently teaching myself VB.net and I wanted to know if there was any other languages reccomended for those wishing to use XNA and if so, good reading to learn these languages. I am currently delving into Jesse Liberty's Learning Visual Basic.net. Thanks for any help Would you consider vb.net an otherwise useful language, I am trying to build the scope of my programming knowledge, starting with XNA useful codes. And any reccomended reading on the C# language Thanks for all the help, it is a great change from my usual dead ends. Any .NET language should work, although if you're not using C# Express you lose some of the benefits of that language. In my opinion, when you're a developer, all languages are use ...Show All

• FritzDeVries XNA Game Studio Express compatible with Visual Studio Professional

  Can't wait to get home and download XNA GSE but I'm concerned; will I be able to use it on a machine where I already have an installed copy of VS Professional I have another machine that I can use that doesn't have any developement tools on it but that would be inconvenient. I checked the FAQ and didn't see anything one way or another. Thanks in advance. If you only want to do Windows games and don't want the starter kits and other features of GSE you don't need C# Express. You can use the XNA Framework with VS Pro. Well you could always just create a windows application project, add the two XNA assemblies references and go on from there (done it with no problems), the installer needing visual c ...Show All

• AdeptBlue How to draw an irregular polygon ?

  Hi .. the question looks simple...but maybe isn't it as it sounds.. I want to draw an irregular shape.. as this : IMAGE2D I would like to know it there are an object and the methods in oreder to to build an irregular shape. How can I tesselete an irregular shape in two dimensions If You have any suggestion please tell me something about it.. I'm a bit confused about tesselletion in this case. Thanks in advance If you just want to draw an outline then jims link goes to an xna tutorial on drawing lines. If you are pre XNA then use the D3DXLine class (C++) or the Line class (Managed DIrect) If you want to draw the whole polygon then you need to perform trangulation.

• CBuilder 3D engine, what to do next?

  Hello everyone, I've been experimenting with the 2d en 3d features of XNA. I've started a little project for myself where I ultimately want to create a 3d graphics engine that supports the basic elements. The goal is not to create a compelling and competitive 3d engine, but simply to expand my portfolio as a programmer. Right now I have the most basic "Hello world" engine there is. I've created multiple viewports with separately controllable camera's. The world currently consists of simple textured skybox, and a grid in the center (0,0,0). I've added support to load some of the DirectX meshes with code I conveniently snatched from the Spacewar Template. I've created a simple SceneGraph implementation and most of the models ...Show All

• Pockey CreateTexture from raw RGBA data?

  I have raw RGBA static data that I use for my textures used by ID3DXSprite. For the moment, I create a new texture of the correct dimensions with D3DXCreateTexture. Then I fill its surface using D3DXLoadSurfaceFromMemory. If I've understood everything correctly, with D3DPOOL_MANAGED a copy of the data is also stored in RAM Is there any way I can create a texture directly from my static data Making D3D use the original data if it needs to reload, instead of storing an additional RAM copy I figured that this might be the case if you create the texture through D3DXCreateTextureFromFileInMemory, but that function don't seem to be able to create a texture from raw bitmap data, only mentioned formats with header data included Also, I'm having ...Show All

• Marauderz Deplacement of sprite, round to int problem...

  Hello This problem make my unit deplacement strange :) i have located the problem, it is cos and sin value. Example : On the X, X = position + speed * cos but if cos < 0.5, it won't move... so it will wait cos > 0.5... so the mouvment will be not realy good... so Do i must save last cos and add it example : double lastcos=0; if cos < 0.5 lastcos += cos; if lascos > 0.5{ lastcos = 0 cos = 0.6 } It may be work (i don't test it) but is there an other method to do this because if i have 150 unit in mouvment fps will be smaller !!!

• Bluehunter Not Using Vector2 in my 2D Game Engine

  I just recently changed, oh, about a 1000 lines of code in my game engine. Instead of using Vector2 for things like position and size, I decided to use floats instead. Does anyone else use Vector2's as their main position and size data types in their 2D game Right now, I have the code for both versions, and I'm trying to make entirely sure floats are the way to go before throwing one of them away. Any comments Since Vector2 is just a pair of floats it will use up the same space as two separate float variables. This is no different in .NET than in C++. So, I cannot see why it would be less efficient to use the struct vs float vars. I use Vector2,why re-invent the wheel That's what XNA is built for. I say use Vecto ...Show All
