I have re-found what used to be a great tool for MC. I used this in my early MC days. These guys made a program that would display MC worlds sliced up in any plane. This would have been a great tool to use with MCServer; unfortunately, they seem to have abandoned the project and it doesn't support reading the Anvil files, is uses the previous map format.

Yup, Anvil support added. Well aren't I good!

First time C# and already such a big task accomplished. Now if only I could get the original author to release the executable "officially"...
While working on the projectiles, I found out that cEntity has really mixed all the rotations. They're named badly, their units are inconsistent, they're sent to the client wrongly and the AI is calculating them wrong. And by trying to straighten all this mess up, I completely broke everything. Now I can't even shoot arrows from a bow anymore; I expect to see fellow players with completely wrong rotations etc. This will be a tough one.
Degrees vs radians, pitch vs yaw vs headpitch (wrongly named headyaw), etc.
Really? Degrees and radians are mixed? wf
Most of the calculations were using radians, but then someone wrote doxycomments that say it's degrees, and wrote wrapping functions for degrees.
I bought a new GPU. I now have the GTX 260 Black edition.
I asume its the XFX GeForce GTX260 896MB DDR3 Black Edition, but why would you go for that ?
Was your older video card even worse ?
You can get 2 of them for 50 euro, unless your upgrading a old pc. i wouldn't have bought it.
