      • This is my first reaction when I installed and tried the 1.0 of XNA. To summarize my feeling: it's still 95% for XBox and no nearer to replace the old MDX 1.0. So I decided not to migrate from MDX to XNA though I want to do that very much. I feel like MDX 2 more; amen to MDX 2. The hardest issue for me is the content pipeline, which is very necessary, but the workflow is fixed and it assumes the c

      • 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

      • Let me start off by saying that I ALREADY KNOW how to animate sprites. I think the way I've been doing my animation, though, isn't really recommended as it can cause hiccups. Here's what I've been doing: I've got a sprite class. This class has a DateTime member called startTime. It also has a TimeSpan member called timePassed. In my constructor I have the following bit of code at the very end: pub

      • I am getting color banding issues when viewing my project on my Xbox 360. The textures look perfect when the app is ran on windows, using the same XNA source just in a different project. 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

      • Hi everyone, I'm just starting with XNA GSE and working on my first game. One thing that is puzzling me though is the LoadGraphicsContent. It seems in all the tutorials I've seen that everyone loads every single graphics resource inside this one function. This seems wrong to me for two reasons, the first is that surely this isn't the most memory friendly way of doing things. What if I have ten le

      • I'm using C# and MDX. When I setup DirectX to go full screen, and then also use GDI to draw on another form on a different display, the Present() function can hang for 10 seconds. When it hangs, even the mouse pointer stops moving. When it comes back to life and I click on a form, it looks like GDI is resetting or something (the monitor goes black for a few seconds, then redraws), and so

It behaves like it should, except when the radius happens to be the maximum value that I've set in code (farPlaneDistance). When the mouse wheel is moved, this changes the near and far plane distance: // don't get too far if (radius < nearPlaneDistance) {      rad

I looked around and saw that in the folder: C:\WINDOWS\Microsoft.NET\DirectX for Managed Code There are many versions of the DirectX dlls, but there is only one version for x64, and that version is 2.0.0.0, which is DirectX10.
