I was just about to delete this project from my eclipse directory and decided I would upload a copy for anybody who might be interested in using it.
Keep in mind this was my first (functional) mutli player 3D game so there is room for improvement, but at least the code is readable 
I used netty and jPCT to make this.

The video is probably not the same as the current build, so here’s a screen shot I took which would be 100% accurate:

In-Game Controls:
- WASD to walk

- Press T to access tiles
- Mouse wheel changes tile/block texture
- Left click = place block
- Right click = delete block
How to host & join
First you’ll need to open the project using Eclipse IDE, then refer to this image:
After you run the client you will be prompted for a username and hostname in the Eclipse console.
You can either type the desired name then press enter, or just press enter for a random username.
The same goes for hostname, where no hostname = localhost, etc. etc. You get the point.
If you need help with setting this up you can add me on Skype and I will be more than glad to assist you.
