      • Hello All, Just to keep things simple, I'll strip my problem to the most basic statement. I'm using C# Express. I've opened tutorial 1 in the DirectX Feb. 2007 SDK. When run, this program displays a blue filled window. I want to render in to a Panel control so I drew a Panel "panel1" in the Form Designer, and I made the following changes to the tutorial co

      • I have a mesh which wraps in such a way that I can not get continous texture coordinates all over, so I thought that I would generate the pixel color with a noise function. I want to generate 3d perlin noise on a per pixel basis, where I calculate for example 5 octaves for each pixel and pertubs its default color somewhat with the noise. The thing is.. I feel that this should not be that dificu

      • Hey all, I've rolled my own version of the SpriteBatch to give myself a little more control (mainly to gain different diffuse colours per corner). However, I've found a problem: When I render the quads at a scale other than 1:1, the edges take colours from the surrounding areas. Here's my control "sprite sheet": http://www.grozzler.com/dump/control.png Here's the result: http://www.grozzler.com/du

I've been looking through tutorials, but so far I haven't found anything useful. Can anyone tell me how to do this, or link me to a tutorial on the subject I'd be most grateful. :D

      • I have a question about the 360 deployment. (I don't own a 360 right now, so that's why I'm asking... I'm planning on getting one this summer.) I know that you need GSE on your computer to deploy it to your 360. But once you have it on your 360, can you unplug, pick up the console, take it to someone else's home (or just disconnect it from net), and still play the game or does it require an active

Is MS planning to release a larger hard drive for the 360 I'm pretty sure that many people (including myself) would be very interested in one.

      • I'm sure this is a fairly simple answer but it's been bugging me for a while. Most of the XNA stuff I do at 1024x768 but recently I decided to change this to widescreen, ie 1280x720. The thing is, instead of actually creating a widescreen play area it seems to just stretch the game from 4:3 to 16:9 which is really irritating. Here is a basic example of what I mean... This is 4:3: http://www.dunman

Some of the transparent textures, especially the info_screen.tga seem to defeat my image editing programs. I have tried to load them in GIMP and paint.net and all I can see is the alpha channel. I get the same result from the DirectX texture tool but when I run the game or render the s
