  Hello, I'm sorry to be such a noob, but if you have children, please consider offering me some assistance. I'm studying what it would take to put a SCORM compliant Learning Management System like Moodle ( http://moodle.org ) on XBox Live with the goal of offering downloadable eLearning that would lead to "Achievements" in things like basic math, geography, and other academic topics, in an entertaining manner.

• Will Merydith texture fetch and shader math execution time in special cases

  Hi, when I do successive texture fetches using the same texture coordinate, without doing any other texture fetches in between (doesn't seem to make sense, yeah, but it does in my context :)), does it mean the value I receive is already in the texture cache And is the tex. fetch thus quicker than a random location texture fetch Another question: when I do some mathematical computations in a pixel shader and one operand is always 0 so that the result is 0 as well, are these computations executed quicker than in the case when the operand is != 0 so that the computations actually have to be executed to receive the result Best Regards Nico Oh, and to your statement: ...but you might find that the HLSL co ...Show All

• stallion_alpa Suggestions needed on translating a DirectX game to XNA

  I have been developing a new 3D puzzle game for the past few months using C++ and DirectX. Now with XNA, which I'm excited about, I'd like to translate my current work and build it up even further. This is very exciting for me since one of my original goals for the game was to make it playable on a console. The game is currently available here http://www.obscurityfactor.com I looking for any advice or recommendations for converting what I currently have. Such as should I wait for the Content Pipeline to import my models, rewrite my .obj importer to work in C#/XNA or try to find a way to convert my models to .swm. All I've managed to do with XNA so far is make a bitmap font class, and the forums have been a great help in understand ...Show All

• swan_sg Discussion on the "challenges" in the tutorials?

  Hello, Is there anywhere people are discussing the "challenges" that are posed in the included help file tutorials for GSE As an example, at the end of the first 3d rendering tutorial it suggests an optimization you can try to flex your brain a little bit. I'd like to get some feedback on the solution to that I came up with... Thanks! -Ben Well gosh in THAT case... :) I created two additional Matrix variables at the class-level (class variables I don't know the correct term) Matrix viewMatrix; Matrix projMatrix; And then modified the LoadGraphicsContent method to include the following loop, taken directly from the Tutorial: //Calc the view and proj matrix foreach (ModelMesh mesh in myModel.Meshes) ...Show All

• Wizzie Problems with: Detecting if a user clicked on a 3D object

  I'm rather new at working in 3d at this level but not exactly new to C# and definitely not new to 3D models... but I usually work with a tool such as Blender, 3DS or Maya. I have my simple mesh object and it displays just fine. When I use the sample code as a guide, I find that I need to make my own Bounding Box... and I understand the process in theory but applying it to the code is giving me fits. **************** Issue1: Using a Bounding Box with the dimentions of triangleBB in the sample causes this: Nullable < float > result = pickRay . Intersects(triangleBB); // Returns NaN regardless of where clicked. That's my shorthand... pasted code with what it results in after the comment.... Question... so why ...Show All

• Saqib Shazhad question about ATI 3D Rage pro

  Is my ATI 3D Rage pro graphics card fully compatible with XNA or do I need to upgrade, and if I upgrade which ATI card will work the best with XNA The only ATI card that I could get ahold of in my area was an ATI Radeon 9250 PCI will that card work with XNA If you are looking for a shader 2.0 card, I think you should go for 9600 and up. However, I don't think you can get that in PCI. Your best chance for a PS 2_0 card is a Geforce FX5500 PCI. Unfortunately the ATI Rage Pro is a little bit dated for XNA. If you want to buy a new card you should check first the graphics slots of your motherboard. ...Show All

• Visions.net DreamBuildPlay is up!!!

  Now go register!!   Actual contest details to come the week of Feb 5th Hmm... State location and phone number seem to be USA specific. An oversight, or is the rest of the world excluded Plese, Someone at Microsoft.... the drembuildplay site, even though the competition should be global, does not allow non-US people to register. I don't live in the U.S., so I can't choose any state, the zipcodes in my country are 6 digits long, and the telephone numbers are not in the US format.  Edit: didn't see errolian's post before i posted this.

• yromanen Reflection on the 360? / Scripting Languages for AI

  I'm wondering if the version of the Compact Framework that will be running on the 360 will support the Reflection APIs in the .NET Framework. I ask because I'm doing some study on implementing a scripting language for an RPG. If Reflection is supported, then I can possibly use C# as my scripting language. If not, I'm looking at implementing my own scripting language (which has its own appeal to a geek like me :D). What are your thoughts You could use Emit in the content pipeline. You might have to do something funky to get the assembly loaded within your application, but the content pipeline is run on your PC, where the full .NET framework is available. IMO, if you're building a scripting la ...Show All

• Olyx Video/Animation Playback

  Hi, I'm currently writing a library (for XNA/DirectX) for animation/soundless video playback, and I have a few design questions for the pros out there if you don't mind answering them : I'm having my animation class inherit from game component, and update the frame depending on game time in the overriden Update method, and render it in the overidden Draw method, but even when I preload my textures to render, playback is choppy. Not sure exactly why, but I notice this only when I have significant number of frames (I noticed it with 100 frames, but *not* with 10/15). This problem may be linked and solved by the 2nd point, so please read on. When I preload all the textures for the frames in the animation (and the no. of frames ...Show All

• apunater Texture diffusing...

  Hi all - my question is how can I get textures when drawn not to diffuse. This happens when the destination rectangle is bigger than the source rectangle - instead I just wnat to "magnify" the image...stretching the texture out horizontlaly, vertically, or both. With everything I try I either get diffusion (i.e. the image fades as it is stretched, making it semi-transparent), or I get pure black. :S Please tell me what I need to do if possible - thanks very much. Alex Shellacc, sorry I just realised one of your posts. Your link doesn't seem to go to an image though. :S Thanks Thanks very much - I'll be testing it ASAP. ...Show All

• williambeaker Render target save'n'restore

  I've a func that do some work including rendering into rt. So, i need to save old rt at the beginning of my rendering, and then restore it at the end ( when smb call my func, he may have rendering to texture enabled, or just rendering to the backbuffer, and he don't wont to worry about restoring his rt after call of my func ). Is there any way to implement such a behaviour using XNA And what if i want to save render target on PC. The PC version of XNA uses the same code path. Basically, you can't get access to the PC-specific multiple render target switching through the XNA API, in order to stay compatible. OMG. Did you really understand me I can't implement my ow ...Show All
