• xyte Texture without shaders

  Is it posible to texture a primative without the use of a shader (Like in managed DirectX) All the tutorials seem to use a effect to accomplish this. I'm asking this becouse I want to keep the system requirement for my program as low as possible. You can use the simple effect that runs a shader behind the scenes No. XNA is a shader based platform, so it is impossible to draw anything without using a shader. ...Show All

• cssjm Transparent Backgrounds on Sprites?

  How do I display a sprite with transparency for the background GIF files do not work. I can't seem to create a PNG image with a transparent background in Photoshop 5. Yes, this information should be added to the "Your first XNA game" tutorial in the help file. It's even mentioned when adding a sprite you can choose to create a texture with masking but fails to mention that you need to set this AlphaBlend. Thanks a lot for the info! Thank You that was it!! Awesome response! Well, first in your code you need to make sure that in the Draw() procedure when the sprite batch begins to draw that you are passing in the AlphaBl ...Show All

• shmulik_segal Text in texture with effect

  I am currently making a component for a larger graphical system. It is rendering text into a texture for display on some 3d object. I am currently using drawText, which works just fine, though there is perhaps a better/faster way of doing it My question is about effects. If I want the text to have a blurry outline, i imagined doing it like this render the text to a texture T1, being the render target select T1 as input texture and change to a new texture T2 being the render target Select a pixelshader and then render a transformed and projected quad, with same size as T1 and T2, using T1. The pixelshader shall then output (to T2) the mean of a 9x9 area surrounding the pixel in T1. This gives a blurred text. Next I ...Show All

• Pavel Nechai Rotate an object

  I need am 2D object to be rotate 90 degrees each time a press down a key. What would be the best to do this. I have try to use TransFormatins of a vector but I can't ge it to work. I know that. I need it to rotate on command when I press a button or a mouse click. I need something better because I will have from 3-20 object doing thing at a time. Some with rotate +/- . There's really nothing better than that. You know how to detect Mouse clicks and keyboard input so when the user press that button. Increase the rotate value for that object or objects that need to be rotate. Then when they are drawn, you use that current rotation value. You really can't get much better ro ...Show All

• Bill Punch Next Beta (SKD)

  Hi, When the next Beta/Sdk to the XNA will be available It will be as Direct X Sdk (available each 2 months) Which will be the next features to the XNA Tks Nothing has been announced. In fact it is not known if there will be another beta before RTM. See http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=746593&SiteID=1 In addition there has been no announcement about how often XNA will ship so we don't know if they will follow the DirectX model or not.

• Terence Curd how to define On Mouse Over eventin DirectX

  I wish to create some onmouseover event function, can anyone tell me how to do it in DirectX, i've checked some example from DirectX tutotrial, the addbutton function got on mouse over event, but it's already preset in the library. If I want to set OnMouseOver event in my own code, what should I do. Thanks. I think i'm using DXUT to create my UI Hi kenneth1983, i porpose check your mouse whether over button x, y, x+width, y+height. Best Regards, I didn't see any onMouseOverEvent in the coding, the onMouseOverEvent is from the dxutgui.cpp The onmouseoverevent code below I copied from dxutgui.ccp CDXUTBUTTON Element.TextureColor.States[ DXUT_STATE_NORMAL ] = D3DCOLOR_ARGB(150, 255, 255, 255); ...Show All

• WayneSpangler Texture Alpha channel problem?

  Hi all, I created mesh.box object with my game. The mesh has a texture. I want to set the mesh alpha channel 80%. How to change a mesh alpha channel for c# Below is my source code. //create mesh object boxMesh = Mesh.Box(renderer.Device, 100,100,100); //========================================== //on paint renderer.Device.SetTexture(0, texture); boxMesh.DrawSubset(0); //============================================ Best regards, Best thing for your purposes is to set the Material’s alpha channel to 80% instead of texture’s. It’s much more efficient as you don’t have to lock any resources. Then, use the propper AlphaBlend mode in DirectX to redirect the AlphaBlending to material’s alpha. Hope this ...Show All

• leclerc9 Newb question: different textures for different resolutions?

  Hi there, I've made a couple of games in GSE now, and in each case I programmed the game in 800 x 600, which is rather silly given that I have a monitor that supports resolutions all the way up to 2560x1600. I understand that I can get the user's window size and adjust my game to fit it at startup, though I haven't really played with that yet. But what about textures Is the best practice to include one texture for "maximum" resolution and then let Windows scale it down to size depending on the user's window size Or do developers include several copies of the same texture for different resolutions Likewise, I'm wondering how to handle different aspect ratios. To release a game that supports both 4:3 and "widescreen&q ...Show All

• Henry Wu 3D presentation

  Hi guys, I really want to waw my client and write a window display for a real estate shop using C# and managed DirectX 3D. It will be a presentation running accross 4 screens.

But, I'm lacking ideas really of how to present pictures and info about apartments and houses... Could anybody possibly inspire me Thanks! Cool tool, but really, the content needs to be dynamic... So I'd need to use models and C#. I was thinking more like, 2 adjacent walls with a number of tiled property adverts. The camera moves from advert to advert in a fluid motion. Each ...Show All

• Carl Daniel Updating child transforms when transforming a parent

  I've got a question about updating the transforms of child objects in a hierarchy. So far I can get a model loaded up no problem using the code from the Help Docs topic "How to: Render a Model." What I'm trying to do is rotate an object in the hierarchy of my model and then update all of the children underneath that particular object. The end result I'm getting is the object in question rotates, but none of its children do. Here's what I'm using to rotate the object: foreach (ModelMesh mesh in m.Meshes) { foreach (BasicEffect effect in mesh.Effects) { effect.EnableDefaultLighting(); effect.View = view; effect.Projection = projection; if (mesh.Name == "LeftArmBase") ...Show All

• DimSum XACT postmortem from a sound designer

  Hi all, I’m on the tail end of initial implementation of sounds created by the XACT engine and I figured this forum deserved a little postmortem (even though its not dead quite yet) that covered the XACT tool, the process, and the implementation.

• GlenAtMotorola XNA framework for non C#

  One of the great advantages of the .NET framework is that developers can work on the same project in different programming languages. As I'm reading about XNA, it seems that this will not be possible with the XNA framework. Will the only programming language that has access to the XNA framework be C# That's correct the XNA Framework is for Managed Code Development and runs on the Common Language Runtime which prevents a programmer from using unmanaged languages (C++) from using the XNA Framework. Managed C++, now called C++/CLI is something that could work with the XNA Framework. All this said I understand where your coming from Mossa and it's good feedback. vb please, some of us did not go the c# route ...Show All

• MarkBosley Character Animation

  I am very anxious getting started on character animation with XNA. If I use a model editing and animation software like 3ds max I could set up my key frame animation incl. bone structure in 3ds max, export this out over *.fbx, what is supported by XNA. However, as far as I know there is no support for animation over the content pipeline. Is there anybody out there, knowing how to do it, who could actually show me the way or point in the right direction Help on that important issue is very much appreciated. Is there a resolution to be expected with the next release of XNA waruwaru, I run the XNA requirements checker. Everything seems to be installed, still having the same problem and error. ...Show All
