      • I just finished a basic billboard class that is capable of reading in multiple textures and animating. However, I would like to read in a single texture file and be able to simply change texture coordinates to change the appearance of the billboard. Now, I could recreate my VertexBuffer each frame, but that would be a lot of wasted processing. Is there a way to dynamically alter the texture coordi

      • So in C# when I do -1%something I get -1, which means I can't really use it as an array index without a bunch of stupid error checking.  Is there some way to force the modulo operator to actually give me numbers from my field (e.g 0-5 for modulo 6) Edit: Well, I made this post at 2:00 am and it shows, here is what I have issue with: i = (i+1) % 6 will result in numbers from 0 to 5, whic

      • I have been learning HLSL. I'm wondering if anyone knows if shaders could be used to assist in rendering curves, variable width lines and line types It seems that some trick fragment shaders could accomplish this. For line types a 1 dimensional texture in the alpha could have some possibility's. Has anyone tried this This could really help in using XNA for other apps besides games.

      • 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

But when I display the textures on an Xbox 360, I get serious color banding. These issues are most pronounced when my Xbox is set to output at 720p or higher resolutions, but the color banding is still there even
