• Dwebs I'd like to have a game developed...but I need a partner.

  I teach 1st grade. I have an idea for a simple 2D (Phonics) game...but I don't have any skills as a programmer. I wanted to know if any programmers would be interested in a partnership   The game basically involves a little character running around the screen to pick up letters and form words. The character would have to avoid certain obstacles on screen. The game would require a lot of speech to sound out the words that the onscreen character created. (George Clingerman)...That Jelly game looks fun. Is there a way I can play it on my PC Maybe you could expand the grid and include more numbers I wish I were like that.

• furmangg Point Sprites on XBOX 360 causes crash

  I have an application that draws a large number of point sprites on the screen using DrawUserPrimatives using additive blending. This works fine on the windows version, with around 4 million point sprites being rendered. On the XBOX, when there are greater than around 20,000 sprites nothing draws and then the program exits with code 0 and no error messages. Any insight into what I'm doing wrong -Adam Here is the relevant shader code: texture Texture; float4x4 WorldViewProjection; float alpha; sampler TextureSampler = sampler_state { Texture = <Texture>; MipFilter = LINEAR; MinFilter = LINEAR; MagFilter = LINEAR; }; struct VS_OUTPUT { float4 Position : POSITION; float4 Color : COLOR0; float2 TextureUV : TEXCOORD0; f ...Show All

• CIAndrew direct3d retained mode: upgrading to IDirect3DRM3 from IDirect3DRM

  My application uses the old direct3d retained mode system for a 3D GUI and the original interface objects (IDirect3DRM, IDirect3DRMDevice, IDirect3DRMFrame, and the others). I now have a need to use methods in IDirect3DRMMeshBuilder3, but to use the "3" version, the other objects have to be the "3" version. However, to start the process Direct3DRMCreate is used to create a IDirect3DRM object, which used to create other objects. The latest "3" version objects require an IDirect3DRM3 object for thier creation--the problem. Direct3DRMCreate can not create a IDirect3DRM3 object and I don't see a Direct3DRMCreate3 interface. What am I doing wrong You have to use Query ...Show All

• Marc Developer Determine which controller pressed first

  I've looked at the SpaceWars and various other samples but I can't seem to figure out how to accurately tell which controlled did something first. For instance, lets say I have four controllers and the first one to press the A button wins. Since everything happens in a loop, there's no accurate way to tell who exactly pressed the button first. I'd have to check each Players GamePadState one at a time and I can't derive from the GamePad class so that's out. Anyone out there have a solution or a similar problem Maybe I'm thinking too much like a event driven windows programmer to see the solution. The chances of two players pressing the button at the exact same instant is very low. If your game is runni ...Show All

• daydreamsy2k componete becomes a property of another component

  in the video of the video of presentation of componetes “Game Components Dem " minute 9, the presenter writes “Spinner” and componete becomes a property of another component. When I do it in my component I cannot accede, to the object, of that form so that To hooking up properties that are GameComponents, you don't need to do anything special. There's a bug that doesn't allow design time assignment of GraphicsComponent based properties, though. If I understand correctly, you are creating your own custom game component that can reference another type of game component and having trouble allowing the UI to specify the other component at design time You can use a TypeConverter to do this. TypeConverters are one way you can ...Show All

• Jon Braganza What's up with deleting posts mech commander downloads?

  I just don't get it. My posts have been removed, I mean any <fill in the blank> could just google for the keywords and get a bunch of legit game sites that host the shared source code (since it was released for free) and yet on these forums it's all hush hush untill MS fixes the link What gives MC2 is not intended to showcase or be related to XNA Game Studio Express functionality (it was previously released as a sample for XNA Build, a different XNA technology represented on a different forum), so it isn't relevant to this particular XNA Game Studio Express forum. Amy Nevermind, this point is moot. The action just doesnt make sense. ...Show All

• TedWagner Clipping Layered Sprites (UI Related)

  You know how in a panel if a child button runs off the side of the panel, it gets clipped. Does anyone know how one might go about doing that with XNA Or how they do it in OpenGL/DirectX Are they doing something with the stencil buffer How do you solve the problem of a needing to nest begin and ends Because the sprite batch blows up horribly if you try to start a new begin before closing the last one. Nick, Buttermilk (my game's open sourced engine) uses a RenderQueue which queues all the renderables in the game and sorts them by their render state (scissor rectangle included) so that they can be batched as much as possible. It complex, but you can check out how it ...Show All

  hi im using vb.net with managed directx..... i read article saying that managed dx gives 98% performance of original one. i run in windowed mode and disply box is on a picture box i am currently developing a cad like application. the problem is when i have more shapes its getting slowed down. i have done only lines, rectangles and circles. i take the mouse click points and store the shape info into a datatable and while rendering, loop thorugh the datatable and render em. for cirlce im using a for loop from 0 to 30. previous i used 60 but it was getting slowed doen fast. how do i improve my frame rates. im a total newbie and i need ur help.

• Fiddel Is it realistic to create one's own engine?

  I'm not new to programming, but I'm new to game programming and C#. I'm wondering to what extent it's realistic for someone to make their own 3D (or for that matter 2D) game engine. The two projects I have in mind for myself are a turn-based 2D war/strategy game, and a 3D adventure game in the manner of "Dreamfall". On the 2D side, I feel confident I could come up with a 2D interface on my own. I haven't done a lot here yet, but I did manage to whip up a little 2D hockey game without peeking at Bill Reiss's excellent 3D airhockey tutorial at http://xna101.spaces.live.com/ . I've even given my computer hockey opponent a very primitive AI. OK, my collision detection and physics aren't great, but I'm not sure how much I'll need either of ...Show All

• rogupta 3DS Max export

  Hello everyone, I have been trying to export models from 3DS max for use in my XNA program. The trouble I keep running into is that the axis keep getting rotated and/or flipped from what's in Max. In order to test this, I have created a model that acts as an axis gizmo, with a cone pointing down the X axis, a Rectangle down the Y and a cylinder down the Z. I have exported the model three different ways: Max's built in .fbx exporter - The X points correctly, but Max's Z is now XNA's Y, and Max's Y is now XNA's -Z (Left-Handed). PandaSoft DirectX Exporter (with Left-Handed coordinates turned ON) - The same as the FBX exporter PandaSoft DirectX Exporter ( with Left-Handed coordinates turned OFF) - The X points correctly, the Y points correct ...Show All

• pure159112 Hm... Direct3D problem

  Well I was going through the first XNA tutorial and then got to the part right before you make the model rotate and I compiled the program and got a nasty little surprise! there was this error in the Could not find a Direct3D device that has a Direct3D9-level driver and supports pixel shader 1.1 or greater. I'm not sure what it is and how to fix it... so yeah and yes I tried searching for the problem but I couldn't find anything about it. And I wasn't sure how to look up my Graphics card to see if it's compatible but yeah my computer is pretty new! So it should be good right With many plz and thank-you's, -Ri_Kamen Here's a wikipedia article on supported graphics cards, you need pixel shader 1.1+. If you want to know what graphi ...Show All

  Is there any way that I can export the game that I have made in XNA as an exe, so that someone is able to play them on a computer without visual C# I think you want to build the application. goto the build menu at the top then click build solution. or press F6 this will then create an exe file in your /project folder/bin/Release and the project forlder is normally located in My Documents\Visual Studio 2005\Projects You might want to check out NSIS: http://nsis.sourceforge.net/Main_Page You can make your own painless installer that includes the necessary files and bundles all your assets into one convenient package.

• kangalert When will the Content Pipeline be released?

  Can any XNA insider tell me the date the content pipeline released or when will the next version XNA GSE be released some more documentation would do wonders for me right now. i really really hope we get the content pipeline before christmas, its still too far away to release it then. I think they mean christmas. In any case, they included "06", so it's gotta be before new year :D Really anxiously waiting for the content pipeline................ I think this would be a disaster for the content pipeline since everyone really interested in this will have to build it's own pipeline by then. I would say releasing it wi ...Show All

• johnbury XNA - Effects / Shaders

  Hello... Does anyone have a few links to articles on shaders and effects I'd like to see some technical information about them to clarify the questions I have ... Also XNA tutorials about creating them are very appreciated. Thanks The effects and shader stuff is a simple wrapper for the D3DX Shader Framework. Any tutorial about HLSL/FX/etc. regarding D3D9 will do. Or just check the DX SDK samples, full of shaders. And google will help you too... I would suggest developing shaders in a designer application like RenderMonkey or the tool from nVidia (forgot the name, sorry). Even 3D Studio MAX has built in shader support... and can render directly to the modelling viewports, this is lots of fun ...Show All
