[DEV/R39] Havana Emulator Continuation (Java)

[MrJeppe]

Introduction

Hi! None of you probably know me, so I thought it would be appropriate to introduce myself as starters. My name's Jeppe, I've been a long time habbo fan and ragezone lurker since 2010. As a kid I used to dabble a bit with retro stuff, adding custom furniture and the alike but nothing extraordinary. Now as an adult I'm a fulltime backend C#/Java software developer


Project background

With that out of the way, let me introduce the project. Havana is an emulator developed by Quackster which is built for V31 shockwave from 2009 with the goal of recreating that era of habbo in it's perfection with the project

. ClassicHabbo supported all features from that era, including battleball, trax, cameras and snowstorm. To everyone's devastation however, ClassicHabbo had to unfortunately shut down due to a lack of interest of hosting it, but also difficulties putting together a team of people who can help out with hotel management. Thankfully, Quackster released all the files for ClassicHabbo meaning that nothing got lost in the process except for the source files used to run the backend of the hotel.

This is where my interest was peaked as a developer. I've always been interested in private servers in various games and how they're made, but I've never had the motivation to actually learn how to create a private server myself. However, over the past weeks I've learnt a lot about habbo's internal workings, their packet structures, figuredatas and other things. Thankfully ragezone has a large library of information regarding these topics so learning has been quite quick. So now I'm working on the continuation of Havana to bring back the features lost from ClassicHabbo's shutdown such as the support for the R39 flash client and other things.


Progress

The current progress is looking good, where the R39 flash client is nearly complete with a few quirks left to iron out, as well as new quality of life features I would like to add. Luckily the progress has been fast due to a lot of backend features from Havana that can be reused for the R39 client

Questions and answers

Q: Will this be open source?
A: The plans is for this to be open source in the future, I also have plans of refactoring the Havana source so that it will be easier to develop for in the future. I will probably not make a pull request to Quackster's Havana git, since this project essentially rewrites large portions of the codebase and there would be too many conflicts to sort out. I will not rebrand this as another emulator however, it's a continuation of Havana and nothing else.

Q: Why r39?
A: Honestly, after playing ClassicHabbo I personally believe that these versions (v31 and r39) are the most pure habbo versions you'll get. The interfaces are clean and easily understood, you have plenty of minigames to play from the shockwave client while also getting modern features from the flash client. It's a celebration of what habbo is really, joins oldschool and newschool players under a single hotel

Q: Is there a live demo
A: There is a live demo that can be played

where we post regular updates and things we're working on. Be noted, this hotel is not mine but hosted by another person. I'm simply developing features for said hotel. The hotel is not in a launch state either, but a open beta state where people can go and report bugs they find.

Has been a productive week this week! The flash client is becoming more and more stable and thanks to our amazing beta testers we've been able to iron out a lot of bugs this week.

Good job! is very good to see the people interested again in retros! i've started to code making retros ^^
You've said that you used to put some custom furnis on your retros, do you still have any of this customs?
i'm working in a project and this can be useful if you have, but anyway congrats for your project )

Some new patch notes! As people may or may not know, the figuredata for public room bots between V31 and V39 broke. I've gone over the public bots and given them appropriate outfits

- FLASH: Catalogue now shows icons
- FLASH: Catalogue no longer duplicates
- FLASH: Users can now be kicked & banned from rooms
- FLASH: Bots now wear appropiate clothing in public rooms
- SERVER: Users without rights in rooms cannot interact with moon totem anymore
