• enric vives I'd like to develop a path-finding engine for RTS game

  With the increase of the number of C# user, and the publication of the XNA new edition. More and more developer agree with using C# to develop game. And I think the problem to use C# to develop is not the efficiency but the accumulation of language such as various libraries. As far as I know, many 3D graph engines have developed by researchers, and some one have being developing the physical engine. But I can't see any engine for AI, such as path-finding engine(if you see any, please tell me, thanks!) especially for C#. And I'd like to develop a path-finding engine for RTS game, of course, for other grid-base game because of my research of a very effect path-finding algorithm which can cost only 1/100 time of AStar and breadth searc ...Show All

• Tigerwood2006 DirectX book

  Can someone reccomend a DirectX book for experienced OpenGL programmers Thanks, Bob To be specific, there are no books that cover DirectX from an OpenGL perspective (not that I know of at least). Most experienced OpenGL developers I know just dig into the SDK docs and examples. Perhaps some other forum readers can suggest a good book. I dont know its for Experienced OpenGL developers or not. But I have this book and founf it really great will very good explaination and examples. This is written my Development Lead of Managed DirectX Managed Directx 9 Kick Start - Graphics And Game Programming - 2003 - (By Tom Miller) Note: all code is in C# Best Regards, Yes, the DX SDK docs s ...Show All

• deen Change Log?

  Quick question please - is there any way I can find a log/list of changes from Beta 2 to final release Thanks... I still haven't found a beta 2 project that won't recompile to 1.0. All I've had to do is update the references to the XNA.Framework and Game DLLs. One of the guys on the XNA team was to write one up but had to go to England for the launch party there. I expect he'll get to it in a couple of days. That's good news...thanks. I guess none of us really expected it to change much - mainly bug fixes. Even if there's bug fixes, a release notes document that tells us what bugs were fixed would be very useful. It tells us where we can go where we prev ...Show All

• Kaleb Right hand coordinate system in MDX

  Hi, I would like to use Direct3D in the right hand coordinate system and therefore use the respective RH versions of the static Matrix methods. In my book Managed DirectX Kick Start by Tom Miller I quote what is required to perform this task: “Use the view matrix to scale the world by -1 in the Z direction. You can do this by flipping the sign of the M31, M32, M33 and M34 members of the view matrix.” Now in the Msdn docs it states: “The M34 element of a projection matrix cannot be a negative number. If an application needs to use a negative value in this location, it should scale the entire projection matrix by -1 instead.” So basically I really have no idea how to achieve this, any help would be gratefully appreciated Julian ...Show All

• Araki66 Spacewar first run

  Being a complete newbie to all of this C# and XNA i loaded up spacewar click on build then installed the project. Then i ran it and a error window popped up, details said something about a missing something or file not found, i sent a report to MS from the window that popped up. I can see im going to have to buy a C# for dummys book cause im totaly lost as to what to do first... ThankYou JR Nip. All though this seems to solve the problem, maybe in a future release a more convenient process could be added (BUTTON) that could "compile" all the necessary files into a directory of our choosing ready for zipping/distribution.

• anita punjabi Collision detection - Howto

  Hi all, I'm trying to make two objects collide in GSE, actually in a Pong game - between the bat and the ball. I have motion for both, but no collision, the ball just leaves the stage so to speak. Any help would be appreciated. I have looked in the Help, but to no avail. Thank, I'll try the code out tonight, as I'm taking a break for now. Thank you so much I like totally didn't think to put the x y locations in for vector locations. Thank you again. so the question remains if you have a sprite on the screen how do you assign the Bounding Box do it Do you need to do a vector that moves with the sprite LIke masked over it in a sense I have assigned a bounding box to the both bats and the ball, the b ...Show All

• rkwarning Catching/reporting effect file errors at build time

  Hi, Is there any way to set things up in Visual Studio so that fx files get compiled at project build time, and errors get shown in the Output window It looks like currently there is no compilation of effects at build time, but at run time when the effect gets compiled from file, the CompiledEffect will just get set to null, and you'll get a NullReferenceException when you try to make an Effect from it. Maybe instead CompileEffectFromFile should throw an exception if compilation fails, and it should make the compilation error info text available in the exception detail But I'd mostly prefer to catch the fx errors at build time. XNA is lots of fun, great work! -Mike Ah, you're right. The ...Show All

• Tarek Ghazali 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

• tenchyz Loading a Model from a List<> problem?

  Hi, I`m storing info in a list which I`ve written: List < float > mapList = new List < float >(); I`m storing mapList[x] = `ModelName`, mapList[x +1] = `ModelpositionX`, mapList[x +2] = `ModelpositionZ` amongst others. ..and would like to. DrawModel( mapList[x], Matrix .CreateTranslation(mapList[x +1], 0, mapList[x +2]) ; Which gives the error: Error 2 Cannot convert type 'float' to 'Microsoft.Xna.Framework.Graphics.Model' : for mapList[x] above. Is there anyway I can convert mapList[x] so its accepted I`ve only just starting with lists and arrays, which one would be better for the type of thing I`m doing above Any information on any of the above would be great.

• Bulldog.NET Managed Direct3D 10

  Since XNA only supports DirectX 9.0 Where is Managed Direct3D 10 I hope there will be Managed wrapper for Direct3D 10 thanks   Jononet wrote: XNA only lets you use an entire window for the graphicscomponent. This is not much use to people like me that make business apps with 3D elements in them, for us being able to create a device in a control within a Windows Form is essential. Our applications are never going to hit the XBox so we would end up moving away to OpenGL libraries rather than use C++ which is too much of an overhead in a RAD environment. Though it's not stated in the docs, XNA does in fact let you manually create the device and render to a control in a ...Show All
