• d72e4d MDX or XNA i don't understand which to use!

  I first started MDX programming about a year ago, to create a simple 3D viewer app, after creating the app, I stopped and didn't touch mdx at all since then so i have forgotten quite a bit of it. Anyway I was suprised to find that mdx seems to be phased out and this new XNA thingy is replacing it. Is XNA just for games on xbox360 I am not interested in xbox360 or games programming, only programming 3D visualisation apps for windows pcs. I don't know if I should still learn MDX or learn XNA, i don't want to learn something and just have it phased out again... Any advice would be appreciated. ='( XNA is fine for non-game apps, just make sure you treat it like mdx (i.e. don't use any of the Game/GameCompone ...Show All

• Simon Clemen How to access the graphicsDevice from a new gameComponent

  Alright, I'm fairly new to the C# language so it may just be an issue with that. In any case I'm trying to figure out how to access the graphicsDevice from a different gameComponent. For example I want to create a SpriteBatch in a gameComponent in which the GraphicsComponent was not created in. So how would I go about accessing it I don't know if this is just me being an idiot and there is a simple solution or if something more complex needs to be implemented so any help would be greatly appreciated. Thanks! Wow! Those are the best answers I've ever seen. Thanks a bunch it helped a lot! Here's an example class showing you how you can inherit from GameComponent class, ...Show All

• Stéphane Beauchemin loading textures on array

  Hi i am making a simple pool game and have my balls in an array (each ball runs through a class to set the properties. i have a Texture2D property to set the texture so i can set the white ball colour and yellow and red ball colour. however i have set up the array and try to draw but it will not accept the array property as a texture it keeps saying it is of null value even though i have set each of the balls here is the code below as you may understand a little more. //ball class for each ball public class balls { public Texture2D tex; public float x; public float y; public Vector2 v = new Vector2 (); public float r = 12.5f; public float m = 10; } //array of ball ...Show All

• Yustme XNA Viewport in standard C# Application?

  As the title says. is it possible to render an XNA window inside a normal windows Form, so i can use normal controls that interact with the XNA area Warning: this is not a reply! But yes, you can render to any window you like. The trick is not to use the Game object or GraphicsDeviceService: just construct your own GraphicsDevice manually, passing the target window handle to the constructor. I haven't done this recently enough to remember the exact parameter name. See Not a reply at all. You need to do something like this: PresentationParameters parameters = new PresentationParameters(); // fill parameters GraphicsDevice device = new GraphicsDevice(GraphicsAdapter.DefaultAda ...Show All

• Vidhya Sagar Deployment Woes

  Whenever I try to deploy my application, either with Publish or manually, it runs completely fine on my computer. When I try to run it on any non-GSE computer, it comes up with a generic/unreadable error message. The computer has DirectX9c, .NET 2.0, and I installed the XNA Beta2 Redist. Are there any .dll's I might be missing I even tried to run the default XNA project and it failed. What am I doing wrong You are currently not able redistribute you applications to non GSE computers. You need to have the environment installed. Generally it is not desierable to distribute applications made with beta versions of software. This is because the beta code may well be obsolete by the time the final releas ...Show All

• maverick_majnoo Collision Detection With Bezier Curves

  Hi, I'm currently making a small 2D game in XNA Game Studio Express. It involves a player moving around a terrain and being able to collide with it. Nearly all the graphics and settings in my game are user generated so this allows for everything to be quite customisable. For collision detection the user specifies paths made of Bezier curves which are stored in a file. The game reads this file and stores a number of points on the curves in an array. The player is also made of Bezier curves that are converted into points: This shows how I want collision detection to happen; if any of the lines that make up the player intersect with any of the lines that make up the terrain, then a collision has occurred. Once a collision has occurred two t ...Show All

• Manik Gupta DLLs on the XBOX 360

  I don't know if this was posted elsewhere on the forum as the search function keeps giving me errors. Is it possible to construct a DLL in C# and then deploy that to the 360 This would be very useful, especially for those like myself who are making an engine that can be used for a variety of projects. Yes, you can do this by creating an "Xbox 360 Game Library" project. Its output will be a DLL that works on the Xbox 360. You can then either reference that project or the built class library from any other "Xbox 360 Game" project. --Stephen ...Show All

• rahulmanasa Cylinder between two vectors

  I have tried rotate this thing on every axis and I still can't get it right. what I am trying to do is draw the single bond between two atoms. Does anyone have an example of the math and steps to do this. I have two atoms in my world and I have the cylinder(bond) in between. I just can't get it to rotate 90 degrees into place.If the cylinder is laying on its Z axis that mean my Z axis is pointing straight up. What am I do wrong Build a matrix with D3DXMatrixRotationX() and pass it the angle (in radians) then use this matrix to transform your cylinder... Read more about transformations in computer graphics, it will explain a lot to you. The SDK docs contain a section about transformations in the Pr ...Show All

• Kardi Direct X 7 Direct Draw alphablending

  Hello, I'm currently using Direct X 7(Direct Draw) & VB 2005 Express. I've already encountered some problem and solved it, and this might be the last question needed to accomplish my work. By Jack's help, I've found DirectX4VB.COM which has several useful examples and descriptions. But since it has based on VB 6, there were several techniques unappliable under VB 2005. Especially alphablend( - I really need this technique to fade in-out a surface)function. It contains following reference declaration and it requires custom DLL. is there any easy-alphablend or gamma-control(for only specific surface) example or description for DD7 I appriciate your kind answer. I've looked into several DD7 alphablend samples coded by C, but ...Show All

• Ragnarok Bounding Box of a Model after rotating (and scaling) it.

  Hello :) I was wondering how I would go about getting the (axis aligned) bounding box of a model after rotating and scaling it   You can transform the box corners by the model's matrix, although since it's axis aligned it won't be useful for testing. Thanks for the answer CodePfo, yet I fear simply rotating the AABB is not quite what I am looking for. Rotating a model can change a model's AABB considerably. Think of a model shaped like a long tube for instance. When it is positionened along the z-axis it's bounding box is simply an unrounded version of the tube. Position the tube diagonally in the scene and the its bounding box will look completely dif ...Show All

• fbiots XML usage on 360

  Okay, so a simple query. How to I use an XML file when when developing for the 360. I can do it fine in windows, but as of yet I am completly lost on how to load the file when on the 360. Have you tried it on the 360 Thank you :) If you don't have a lot of nodes in the XML file that would be fine, but if you have something like 50 nodes that you need to iterate through it might get a little messy with 50 if statements. Depending on the content of the node you could just pass the XmlReader or XmlNode to a class constructor or function or some such and make it a little neater. This works on the 360 as well, not sure of the performance implications though... ...Show All

• Stefan van der Merwe XNA Breakout

Code is at http://joshmackey.net/programming/XNA/XNA%20Breakout/ Haven't looked through all of the code yet, but I liked your idea of StateManager. It's very, very similar to the one I'm using in my own project, but now I noticed there's a few things I can definetly use to improve my implementation!
