• AngelOfPirate Communicating with C++ DLL

  Hi, I am having some C++ code written that will create a triangulated model for me. I will be rendering this Model in managed DirectX , so I need to decide what is best way to communicate with this code. I will be using a Vertex and Index Buffer to render the model. The choices as I see are: 1) Use C++/CLI. Performance of the Model generation is of the utmost importance. As I understand it, with C++/CLI we can retain the power of native C++ but as the DLL ultimately created from the code will be managed, we can do what we want to communicate between assemblies. The author has no experience of C++/CLI, but may consider going this root. 2) Use Platform Invoke to communicate with a completely native ...Show All

• jkhjgszd Game components

  What is the idea behind the GameComponent class Will it be used for input handling and audio handling, so you won't have to use the keyboard classes and audio classes, or only for graphics and graphics extensions Don't think of 'em, Jim, write them up! :-) Jim Perry wrote: Cmon, I'm still at work, only so much I can do! hehe, I hear you there Jim. I can't wait until I go home tonight.. uhoh boss is heading my way ... Cmon, I'm still at work, only so much I can do! GameComponent is really just a kind of glue for packaging up functionality in a way that can easily be consumed by other developers. So it's mostly up to you guys what kind of components you w ...Show All

• John Sudds - MSFT Will XNA Game Studio Express support multiplayer? (on the 360)

  Please, please tell me that XNA Game Studio Express will support multiplayer... Singleplayer games are fun, but multiplayer games are 10x as fun. Thanks for the clarification.   Jim Perry wrote: Even if it is early-mid 2008 how many people are going to have a game ready for multiplayer by that time Very few I'd imagine. Well, no one will, of course. You can't get a game ready for multiplayer if the devkit to create it doesn't exist yet can you ... and that's exactly my point. Seems it will be ages before we can even start to creating the things we want to. DT. Edit:  After reading further I see these statements from MS representati ...Show All

• Jason Swalwell Array with a variable instead of a number

  in my program I have the following code: int Blockers = 4; Texture2D mTexture; Texture2D [] tBrick = new Texture2D [Blockers]; so anyway, this gives me the following error "A field initializer cannot reference the nonstatic field, method, or property " , underlining the Blockers word in the 3rd line of code above. I also have several other lines similar to this one declaring Integer arrays, which give me the same error. The only reason I'm trying to do this is to make it more 'Dev friendly' so that anyone can just change the number of 'Blockers' and create more bricks in my game. ; If it is only for development purposes, just replace int Blockers=4; with const int Blockers=4; Ma ...Show All

• Vijay R Area in Form for DirectX stuff

  I have simple question. I want to have some area in form for directX animation (not whole area of form) because I need some space in form for other stuff, buttons etc. I am using Microsoft Visual Studio 2005, managed directX 9 and C# I managed something but that is not it, so if someone can help ... thanks Sorry, I didn't wrote that this is the way I tried and it didn't work.

• Talyrond Raytracing with DirectX

  [original question from split thread http://forums.microsoft.com/MSDN/showpost.aspx postid=1274336&siteid=1 ]  As a sidenote, if you know, could you explain to me the relationship between Shader Model 3.0/4.0 and DirectX9/10. I've read the documentation, but am a little confused. If a motherboard supports DirectX 10, does it automatically have support for SM4.0, or can it be DX10 and still only have support for SM3.0   Actually, there is a case where some new motherboards support DirectX 10. The Intel, DG965WH says in its manual:   http://www.intel.com/design/motherbd/wh/wh_documentation.htm that it does support DirectX 10 through the onboard video chipset X3000. There are conflicting reports on the int ...Show All

• foleypro XNA Architectu "push" vs. "pull" model

  Xna.Input.Keyboard has no events OnKeyUp and OnKeyDown, so I can't subscribe any object on this events using delegates. Is any reasons - why I know that I can do this by myself (examine the keyboard state every Update and call those events), but it's an ideological/archetectural question: I don't want to "pull" keyboard every time, I need my objects to be "pushed" on a keyboard event. In general, "push" model improves scalability and maintainance of a system since It's syncronous - each object reacts the event immediatly when event call occur. You don't want to do this as much as you think you want to. The problem with a push model is it forces everything to respond to information at a ce ...Show All

• Wellnow Fps is at ~60 all the time?

  Hello, I'm total noob with XNA so please bear with me :) In xna beta 2, designer is now gone, so to access IsFixedTimeStep I have to do this in code: public Game1() { graphics = new GraphicsDeviceManager(this); content = new ContentManager(Services); this.IsFixedTimeStep = false; } Problem is that it always shows fps at around 60 no matter what I do - draw some 3d model or just empty screen. I know I'm missing something simple here, please help.. Btw, I'm using one of fps code examples found on this forum, so I don't think problem is in fps code itself.
