Edit: hmm...there was no link. Since I last edited this on 8/26, there has been no link for about a month. Don't know how that happened.
This is a windows installer for the Unofficial HabitRPG-Local server and client. This is outdated, and the last released predates the rewrite. To get the latest code, go to the github repository https://github.com/lefnire/habitrpg and follow the directions in the readme.
This will install a server and client identical to habitrpg.com, as it was on August the 21st 2013, with some distinct differences.
NOTICE: This is a local version that DOES NOT sync with habitrpg.com. You will NOT be able to log in with Facebook, or your habitrpg.com username. If you have a problem with the installation or the local server install, post your message in this forum thread or here. DO NOT post your questions or bugs anywhere else. If you don't use windows, please let me know which OS you would like an installer for.
What you can do with HabitRPG-Local:
1. Create as many user names as you would like, and do whatever you want with them, at blazing fast speeds. Rack up points, get armor, kill your characters. Get drops. Experiment. Go nuts. Do whatever. It's not cheating because it's your server.
2. Access your HabitRPG-Local server/client while offline.
3. Access your server/client from other web browsers within your local network(and even over web). Details below.
The installer installs links to launch the server, launch the client, view the readme, uninstall, and go to this forum thread.
There are detailed instructions for installing at the beginning of the installation process, and a README with more information at the end. I posted the README below.
In this latest installer, I put in some safeguards to protect someone from accidentally overwriting their data, but the data is still solely the responsibility of the owner.
tl;dr: Simple windows installer. Just run, click through it. Don't change anything. If it doesn't work, you're going to have to do a little reading, or just post a comment here.
