It’s been a long time since our last update, but I’ve finally got some time on my hands to get back into things. We also have a new developer working on object plugins for the game too, which have been gradually been appearing in the game since my last post.

Advanced Lighting

The main improvement in this patch is something I didn’t expect to be completed this early into the process, and I didn’t think it would ever be this beautiful and effective. This patch introduces a completely custom lighting engine, built from the ground up for TSO/TS1.

Even though it is not a necessary feature, it’s something I’ve had on my mind for an incredibly long time. Sims games past 1 typically build a light map to construct smooth falloffs and shadows for light sources, with 3 and 4 actually featuring advanced lighting which models per-light shadows in each room. The goal was to bring these later developments back to TSO, now that we have the graphics hardware to pull it off. Wall shadows are projected from each wall “line” in the light’s room, while object shadows are estimated from the object’s collision bounds (both with smooth falloffs).

Here are a ton of uncompressed shots from the game. Click any of them to see them full size!

All of these lots can be found in Sunrise Crater, and were designed when their owners didn’t even know they would look like this! The more complex or natural the lighting setup, the better the result. One adverse affect of this is that I now only obsessively play the game at night… but subtle lighting and shadows benefit the game during the day as well, as they apply to window lights.

There will be a development post detailing the process this lighting uses and how it was developed following this one, perhaps after more core features are implemented. Additionally, you are able to enable/disable this lighting, and any other FSO enhancements in order to improve performance or reduce RAM usage. If your hardware could run the previous version of the game but not this one (DX9.3 target instead of DX9.1), you can disable the lighting to continue playing as you have before.

However! This is not the only change present in this update. Additional core features have been implemented, as well as invaluable new plugins from our latest contributor The Architect.

Friendship Web

Friendship Web is now user friendly and informative!

The Friendship Web introduces core functionality that was sorely missing from the Relationships system – the ability to summarise and search through all your relationships (and snoop through others!). In TSO, you may remember this interface being more of a gimmick feature rather than something useful, mainly thanks to its unorthodox design. To simplify all of our lives, this has been replaced with a searchable, sortable list of all of the relationships you have present. Typical sort modes are available alongside more useful ones, such as “Almost-Friends”, so you can find your next target for getting you that promotion at the Robot Factory…




Over the past few weeks, The Architect has been working diligently on various “plugins” – the interfaces and servers that most of the TSO exclusive objects utilise to drive complex functionality. Since our last blog post, he has implemented the Slot Machines and the Costume Trunk object plugins.

In this update, he has contributed the plugin for the Band group money object, making the creativity skill actually useful for making the big money, a special fun minigame, and two plugins for games and offbeat lots. The first is the timer plugin, which currently lets players run stopwatches or countdowns in sim time. The second is incredibly complex – the Draw-a-Card plugin lets players define a deck of cards, and then draw cards from it on demand. The last is the “War Game” mingame, which I’ll leave as a sort of surprise. You’ll be able to check these out for yourselves ingame!

…and more!


Here’s a list of everything we’re bringing with the new update:

  1. Fully reworked lighting, GPU accelerated light-maps with soft shadowing.
  2. Friendship Web UI – completely redone from scratch for usability. Find the easiest marks for improving your friendship for career goals and other benefits.
  3. Band Group Money Object – A new group money object utilising your creativity, body and creativity. Remember longer sequences for exponentially more money!
  4. Wargame Object & Plugin – A minigame object featuring cool hats. Compete to gain logic skill!
  5. Draw a Card Plugin – Set up a deck of cards for a custom defined game, and sims can draw from it. Chance/Community Chest cards (hint hint), raffles, cluedo, and more are possible.
  6. Timer Plugin – Some extra muscle for your games and events, displaying a real time clock to help you co-ordinate timed actions with friends.
  7. AFK Timer – Saving our servers some hassle! If you do not perform any interactions in 15 minutes, you will be given a 5 minute prompt to confirm you are still present. This is partially to save our servers and boot people who accidentally get “stuck” on lots.
  8. Admins and Roommates can now join lots that are full. Admins have special privileges to delete objects which should not be present.
  9. Pizza payout has now been slightly improved to encourage people to stop playing just Code. (thanks chompers)
  10. Graphics Options for fine grain control on FreeSO specific enhancements.
  11. Money over head for transactions. The most important feature.
  12. Various bugfixes and performance improvements throughout the game. (lot page lag, landing time, object crashes, etc) Pretty much most bugs that have been prominent in our #bug-reports channel, sans the restaurant ones.

Game Balance & Money Lots

We’ve noticed a few trends in the gameplay that are worth investigating or experimenting to change. Players have very minimal downtime from skilling or making money, so they are encouraged to continue doing it forever. While these users may enjoy the variety of social experiences possible in TSO, they are encouraged to forego them to , or keep their skills up. Store lots are definitely essential and make a lot of money, but disallow their owner from enjoying the social aspect of the game. Additionally, there is a staleness where people are all running the same solo jobs or skills, because it is more convenient (eg. charisma is a very useful skill), or consistently pay higher.

While the introduction of core features will restore some sanity to skill balance (eg. object wear, nightclub job, Maze group object), we would like to experiment with new features to bring even more life into the game than was there in the first place. To help combat these issues, we will be introducing dynamic payout re-balancing for solo job objects, additional benefits for more obscure lot types, and more complex systems yet to be announced.  Stay tuned. 😉

Hope you enjoy playing with the changes!

Register at!


Around a month ago, the owners of the longstanding legacy server and I decided to collaboratively set up a test server for people to play in, which would inevitably be wiped as game breaking economy and skilling bugs were worked out. This was purely so people could play the game in its current, mostly working state, rather than waiting for me to deal with my RL business before they could play at all. Our hosts and moderators have proven an absolute blessing in that I’ve been able to put the right amount of time into everything, with them handling support and keeping the server alive.

The server was advertised on the discord and partially the forums, so that the most dedicated users could have a chance at playing first. These aren’t our only users though – we’ve received a lot of attention from various streamers over the past few weeks, which has set off a few communities, top 100 lot competition. At max, we’ve sustained 350 concurrent players in around 60 lots, on one server box. There are just over 2000 lots on the map, and 11,521 avatars in existence. Cumulatively, sims have §75,528,319 in the bank, and have bought §92,393,467 worth of objects (191,956 objects)! Here’s some screenshots of a few that weren’t possible in TSO, from users who’ve put a lot of work in over the past month:

Thanks to this load, I was able to track down a ton of issues regarding lots being stuck open (infinite loops and a bad deadlock in the core vm command processor), various performance issues, and we were able to identify that using MariaDB instead of the official MySQL server greatly improves performance due to the way we are using the database. TSOMania has been keeping track of all the client changes:

Though the servers are indeed up, and I am occasionally submitting changes, I will not be able to devote myself to programming any large scale features, performance improvements or general enhancements until my Masters project is finished. The game is purely up right now just to give you a chance to play it as-is. However, that doesn’t mean there are no plans for the future!

For now, the focus is on bug fixes and stability. Here are the feature plans for the future – at when I have more time:

  • Nightclub Jobs – these are driven by complex plugins which need to be fully reimplemented from scratch. Reversing how the interactions with the objects has already begun, but the gameplay itself will likely have to be custom designed.
  • Friendship Web – Due to the complexity and weird design of the original system, it’s likely this will take an entirely different form in FreeSO. For example, it might make more sense to be able to perform search queries into your relationships. eg. users who are almost friends, almost enemies, almost max, almost min.
  • Terrain Tools – Yes, it is a priority to support what TSO didn’t – fully featured terrain tools like The Sims 1 had. Only – we are also able to incorporate improvements from other games, such as The Sims 2, where floor tiles could be placed on uneven terrain.
  • Roommate Protocol Improvements – The roommate protocol has remained largely unfinished, due to the amount of time that needs to be put in to get the last few features up to scratch. The main blocker is the issue of deleting lots, or moving a sim out of a lot when the lot is offline. This is complicated because it needs to open the lot for the express purpose of moving objects out of it to user’s inventories, and other issues. Fixing this would also allow users to “Retire Sim”.
  • Sandbox Mode – To both develop the game and allow users to develop custom content, they need some way of manipulating a VM where their client acts as the server as well, so they have full control over the game state. This was possible in legacy, but was left behind with the move to the new networking system. Bringing this back would also let people develop custom gamemodes or more interesting sandbox servers where there are no limits.
  • Inbox – The ingame inbox has been largely forgotton about, as it is not necessary to gameplay. It is useful, though, to have some ingame way of messaging other players that are offline, and keeping track of long term events such as roommate move-in or move-outs.
  • More Plugins – Objects like the Casino Slots, Maze and Band job objects, Draw-A-Card object and Timer object require full reimplementation of their custom UIs and logic. These will be worked on in time, though if you are a programmer these are the ideal place to start!
  • Advanced Lighting – In the vein of The Sims 2, it is possible to bake complex light maps for each floor that allow lighting more complex than we currently have. Specifically, outdoor direct falloff lights, wall shadows, indoor direct falloff lights and perhaps even some rudimentary object shadows. Ensuring the performance of such features will be tricky, but it is also entirely possible to manage on modern hardware.
  • Custom Jobs and Custom Content – To make FSO truly better than TSO ever was, we need a long term way of letting our community improve the game, through new functional objects or new job lots. Already there are two plans for new jobs, which aim to break the boundaries of what was possible in TSO with some new gameplay prospects better fitted to The Sims.

Note: the server will not be wiped for a long time – not until these things and some additional backend work is flattened out.

I hope you’re all enjoying the time so far, and I hope you also enjoy what we might have in store in future!


Hello folks!

Though early testing, it’s clear the transition to ASP.NET will work. While Nancy would crash with a pitifully low number of requests, ASP.NET does not drop any requests at all with several thousand. However, as I mentioned before, we did not expect to see several thousand users attempt to register on day one. Admittedly, we got a bit ahead of ourselves; planning to implement many moderation features after the game had been established, due to a rather small expected userbase. This means a few things for us:

Our new projected user count is way larger than our original launch plans allow

Originally, we planned to launch the game with a large starter lot available for users to skill and earn money, until they could purchase their own lots. This is because we would not be able to provide starting funds for new users since registration was free. This plan was devised when I had projected a maximum of 200 initial users, and assumed we’d be able to fit most people on a super lot with a 128 avatar max count for an opening ceremony.

With over 1000 people, we would not even be able to get everyone in the building, and having all new users play at exactly the same time without lots to split everyone into would be a recipe for disaster. Picking a server configuration to allow this many users to play would be a complete shot in the dark – and we wouldn’t know the root cause or true capacity of a server configuration if we were way over it (it would just crash immediately)

Automated Moderation is Required

A large potential problem with launching a TSO-like game with free registration is multi-accounting to profit faster than other users. Unfortunately, it is currently very easy to do this – we do not have any automatic detection for botting and multi-accounting. As mentioned before, it is possible to do this by monitoring one-way transactions, suspicions large transactions, suspiciously predictable command submissions to the game (botting), and other checks. This would be enough to flag the few suspicious behaviours for investigation by a moderation team.

The plan was to implement this soon after launch – as it would take people a bit of time to rake in enough funds to transfer from a secondary account to their main. With over a thousand people, things can very quickly spiral out of control, so it’s important to get this right as early as possible.

Large demand from Brazilian fansites

On launch day, half of the traffic to the WordPress site was from Brazilian fansites. Our English discord even gained a Brazilian-Portuguese channel and voice chat for a short duration of time, since they were talking in Brazilian-Portuguese in the normal channels. This caused a small scale language divide, and only with a few members. With an equal number of Brazilian and English speaking users, the game’s city would experience a harsh language divide very quickly, and the quality of moderation and gameplay would be severely degraded, with half of the community expecting the other half to speak their language.

I believe to solve this problem, the Brazilian community need their own instance of Sunrise Crater. If this were on the same server as the English one, and I were able to take server donations, an imbalance in donations and game activity could mean that one side’s donations would be paying more for the other. I don’t think I would be able to deliver a satisfactory server to the Brazilian community, due to the language barrier. It would be ideal if the Brazilian community could find and elect their own server admin and moderation team to run their server in a way that works most for them. For this to work, I need to make the servers easier to run/maintain, and help a trusted server admin set up a separate server for Brazil. This would happen close to making the revised game server public, and ideally launch alongside our official servers.

I am still in full time education

I was banking on everything working fine for the launch, as the date was actually set as the latest possible before I had to go back to university and work on my final year project. Unfortunately, it doesn’t seem like it was ever actually meant to be – I was hoping I could get a lot more of the required features done, and sort of hoping that some of them wouldn’t be necessary with a rather small playerbase. It turns out that all of these are completely necessary, as manually moderating thousands of players without some kind of automated assistance (reports, transaction flags, botting flags) would cause some kind of mental breakdown.

I also need more server administrators to help keep the server up. Especially in early days, it’s likely that the server will go down, and I can’t be there to keep it up 24/7. If I am also making sure the servers are running all the time, I would have no time to develop the game itself. I’m a feature developer at heart, so it’s crucial to my own sanity that I don’t become a slave to my own server. Unfortunately, the servers are also quite hard to maintain right now – there is a confusing setup for running our watchdog, updating is complicated and sometimes requires a manual restart, and some things like the server nfs on linux need an easy way for casual systems administrators to set up. I will likely pick people I already know to do this, so please don’t suggest yourself. The problem is, I need to make it easy enough for them!

Because of my situation, things have to slow down again (as they have several times in the past few years). However, contributions to the project in GitHub are more than welcome. We can still launch while I am in full time education, it just needs to be well planned in advance.

A new plan for a “closed” beta

We have a few problems to cover. We have no idea how the city and lot servers will scale with a large number of real users, which is a function of how many lots we have open, how many players are on each lot, how many players are idle in city… We do not know at which points city or lot servers could become unreliable, or how they might behave. A large scale instant launch will break these servers so fast it will be impossible to diagnose where any of these issues start.

The solution is simple, we need to stagger the number of players we allow into the city. The current plan is a beta mailing list, where you submit your email to recieve a FreeSO beta invite code some time in the future. This way, we can gradually scale the server up, see how it behaves, and there will be no need to join a large “city lot” style lot to get started (this would only need to be available through the first few invite phases). I’m also predicting that many people will quickly stop playing. An immediate playerbase of say, 2000 users that gradually drops to 750, is a lot harder and more expensive to deal with than increments of 50 to get to the same 750 end users point.

This will be announced on this wordpress when it is available. The emails to recieve codes will probably be picked in order, but it’s likely some randomization will be employed. Please stay tuned.

Revised Roadmap

Here is a list of things that really need to be done so that we can try again.

  • Complete API transition to ASP.NET (require admin api, some bugfixes, testing)
  • More tools for admin UI, for viewing reports, transactions, flags and bans.
  • Transaction logging and automated flagging tasks.
  • Bot detection plugin (closed source).
  • Ingame moderator tools for bans and warnings, and user reports.
  • Ensure the distributed portions of the system work, including distributed shutdown, emergency shutdown of one component into reconnect and distributed update. Required for horizontal scaling.
  • Set up a system to gradually roll the server out to users via email invites.
  • Cleanup hosting the server to be less of an active chore. This will be necessary to start letting other language communities set up their own server, and let me get on with my life on the other side of things.

This large list means that we cannot launch soon. This isn’t a problem of money, it’s a problem of time (specifically mine). This is definitely possible, we just have to do it right. Sorry for getting you all excited! @_@

A note on private servers & instead helping develop the game!

Please remember, if I, the developer of the game for 3 years, could not successfully run a server, that you or anyone else definitely will not be able to run one successfully! Please also be careful of private servers hosted by non-developers. I know that at least one of the groups that may attempt this were involved with the DOS attack a few days ago, and due to their unpredictable nature I would not trust them with any of your user information.

If you have the ability to host a basic server, your time will be better spent helping me implement these features, so we can launch the game for everyone. The MMO server stuff should be rather easy to jump into developing (especially compared to simantics), so if you have experience with C#, give it a shot! We will be accepting pull requests on our GitHub repo.

I’d like to end this post by saying that we will not be accepting any donations until at least a server is open for players to see the game running for themselves, so be wary of any requests for money posted on social media. The TSO community has been burned once before, and I don’t want it to happen again in case for some reason we fail!



Ouch! When we tried to launch the game tonight, the servers literally couldn’t take the insane load that we underwent. Here’s everything that happened:

  • One day before launch, DOS attacks began hitting the wordpress and forum servers. These were mitigated as they were pretty small scale, and against normal web servers which can deal with a reduced load much better.
  • When setting up the API server on our large scale servers, DOS attacks began coming through to the API server recently added to the DNS. These were rate limited, but somehow were still enough to take down the server. It became clear something was wrong with the Nancy driven API server from this.
  • By rate limiting to 10 requests a minute (yikes!) we were able to reduce the load on the registration enough to keep it alive, before it was even announced to anyone. During this period, I was able to log in with what seemed like no issues. In this period, 100 users registered.
  • I released the registration link on the discord channel. The whole thing blew up, immediately 500 concurrent requests were made to the api server, taking it down immediatly. Hours later, these have still not simmered down – there are a few hundred requests being made and simultaneously active. The large delay each of these requests is incurring is causing the majority of them to fail to get through.

Throughout this process, it became clear that there was a serious issue with the amount of load the API server was able to take. I would say that it should have been able to take at least 25x as much load, and it certainly should not have repeatedly crashed. After some quick experimentation tonight, it seems that the HTTP serving library used to create the API server, Nancy, was serving even plain non-sql requests way slower than other libraries.

We also did not expect this many registrations. Of all of the requests, 885 users from unique IPs signed up. This makes things really difficult. I’m only one developer, and the flash interest in a game that basically died of inactivity years ago is very surprising. It’s also pretty satisfying; it is fantastic to see this much interest in FreeSO, it’s just also very hard to manage.

Could this have been mitigated by opening registrations earlier? Could users whose registrations got through get to play the game?

No, the API server does not only drive registration. If we were to somehow mitigate impact on registration, then the impact caused by users logging into the game would bring it down instead. This would be a lot more certain, as authentication makes 4 times the requests as registration. Registration was also not ready until close to the deadline. This is mainly due to the DOS attack to the wordpress mentioned before.

So what is the plan?

We will perform further load and api testing, look into the root causes of load issues and the server stability. The current plan is to rewrite the API server using ASP.NET instead of Nancy, as it is a lot more “battle-tested”. This could take some amount of time.

We cannot announce a retry date. We might even need a new launch plan altogther, to avoid the load of a few thousand users wanting to play the game on day one. Whatever the plan is, it will be posted on here eventually.

The first city the official FreeSO server will feature is the evolution of Test Center, Sunrise Crater!


I originally planned to reveal this on December 25th, but I got a little carried away with the changes and town layouts. The city is now full of small towns and interesting features for communities to spring up around. Each part of the city has been intricately detailed by hand, from within the client, rather than just whipping up some graphics in a standard editor. Thanks to this, the difference is so staggering you might be surprised that this is still using the same landscaping system as the original.


Thanks to the changes to lot background rendering, road behaviour and smooth zoom, your lot is really a part of the world now. All of your buildings will populate the small town areas within the city, and define their character. Eventually, these towns will become formally defined as neighbourhoods, and you’ll be able to define the way your district is headed by being elected by your peers. This is all far future though! Got to get those core features in first. 😉

A few incremental saves I made of the city building process. The vertex colour has been changed to the final in advance, though.

That’s all for now. On January 6th, you’ll get to see it in person, and set up shop wherever you please. When you join on the first day, make sure to stop by the City Hall on the top of the mountain, for our launch ceremony!



Hello folks!

It has been a very long journey. Started on February 16th 2014, the SimAntics & World Development thread was the first attempt at re-implementing the complex Virtual Machine behind both The Sims and The Sims Online. 17 months later on July 28th 2015, we ran our first online playtest, where everyone appeared as Bob Newbie, the server crashed every 5 minutes and many tables were stood within. Now, 17 months later again, for New Year 2017, we’re finally launching the game in the large scale MMO context that we’ve been working towards this whole time.

You will be able to own a house in the city, run a store, skills lot, money lot, service lot, nightclub or whatever you want to create! Breach the top 100 with a fantastic lot, sell your in-game skills and real ones, work your way to the top of the career track with friends or just have fun, there will be a lot to do off the bat.

With new features and objects from the start, the future of the game is looking brighter than ever. The max lot size is now a huge 64×64 with 5 floors, and you can now see your neighbours around your lot. Compliment each other’s views or go to war with your neighbours, or just make a 5 floor castle in the middle of nowhere. As the past few years have proved, I’ll be there to listen to any feedback, quickly fix bugs that pop up, and lead us through the beta period to a full launch. Of course, the launch will fix a ton of bugs and introduce many welcome changes too!


For more information, check out the FAQ here. You can ask more questions in the forums and I’ll put the answers on there, so check back frequently!

In October, members of the forum voted for which city they wanted to live in first. After 3 rounds, you chose Test Center… however, the city has changed a lot over the past few years, so who knows what will be different! All will be revealed on December 25th, so stay tuned.


This has been a long time coming and I’m glad I can finally do this. There’s a small chance that this date might be missed – if that’s the case then you’ll be able to find out here first. There will be more information on the exact time the server will go live and what you need to download closer to the date.

That’s all for now. See you ingame!


Hello again! It’s been a while since our last post, and a lot has changed. First of all, we have completely ditched Bass.NET for a custom solution using only Monogame (like the rest of our audio) and a decoding library called Mp3Sharp. This lets us play mp3 music through the same channels as our sound effects, meaning, you guessed it, speakers ingame (and robot job) can now play game music! No longer are you stuck dancing to silence.

Last month, the simulator underwent one of the largest and most important changes it’s faced recently – the addition of Permissions and checking them.

Giving Maxis our spare key.

But of course, that’s not all. Alongside many quality of life changes, such as the property list and two person object interaction fixes, we’ve also fully implemented sim budgets in a way that will transfer nicely to the global server.

TSO specific game features have always been a priority, since they have not been replicated anywhere else. One such feature, “plugins/EODs”, allows an object to display an interface on the sim’s local machine, and allows it to connect to an “EOD server”, hosted within the object in question. The biggest TSO objects, signs, the nightclub job and pizza, use this functionality extensively to provide interfaces for gameplay simply not feasible within SimAntics alone. The challenge was to implement this “server in a server” system in a way that could easily be extended for all ~20 plugins in the game. As of a few days ago, we were successful!

By far the most useful plugin, the dance floor plugin.

Signs and the Dance Floor plugin, but that’s not all…

Playing Pizza on the night of release!

However, implementing these three does not mean an easy ride for the remaining ones! Each EOD has a custom server which can be complicated (it especially was for pizza! 8 different simantics events, and ~7 freeso ones) and requires a backing implementation for its UI on the live mode panel. Most of the work is done by the UIScripts, however all functionality has to be implemented by hand… unlike SimAntics, where the simulator drives the object functionality from the game scripts!

The Signs Interface. Features 4 different modes, one of much enables a tab to set permissions.
The Dance Floor interface, featuring a cool 25 buttons to queue custom interactions via the Dance Floor Controller.
The pizza interface, which must closely follow the state of the object, who is connected to it and the decisions they make.
The pizza interface, which must closely follow the state of the object, who is connected to it and the decisions they make.

We’ve come pretty far in the past year. It’s still hard to believe that the first online playtest was less than a year ago! You’ll also notice that our Road To Live Release thread only has a few select items left… Crikey, I wonder what this means? 😉

Thank you everyone for following development, and playing what we have so far has definitely been a lot of fun. Great things are to come!


Hello folks, it’s been a while since I posted an update. A number of things have happened since the last post, so I’ll go over them quite quickly.

Firstly, a lot of work has been put into our resource editing tool, Volcanic. It is now possible to make, test and debug new objects entirely from scratch within FreeSO! This is the culmination of 6 months work; you are now able to fully modify and create most resource types that TSO uses.

Rocket in Volcanic's DGRP editor.

Many object interactions have been fixed – specifically the food counters, beds, campfire and bubble blower. There are a lot of small changes, but the gist of it is that now there are very few objects that do not work correctly. The only remaining main SimAntics VM features are permissions, budget, and the “plugins” system that drove things like “Pizza” and the sign posts. After these, we can get started on the MMO server.

…and of course (due to popular demand), grass and other terrain types are now visible. Here are some screenshots of objects users created with Volcanic as part of its user evaluation, grass included:

We also have a new text logo! This was designed with guidance from some of the members of the community, and resembles more of a modern sims feel than an old one. This was really just to make it go with the icon I already created.

freeso logo

You may have noticed that the forums are currently down. Don’t worry, we haven’t gone anywhere! They should be back up soon, but while you’re waiting here’s a little teaser for what I’ve been working on. 😉

For all you anti-forums folk, a lot has changed since the last update. The change suit primitive now works correctly, TV sounds are half working, and most importantly the game can now serialize and deserialize entire game states, avoiding the huge wait times people were seeing when connecting to servers.

Chat bubbles and chat history have been added, a ton of bugs have been fixed, and work has begun on a full Independent Development Environment for SimAntics to let users create their own objects! (and us modify existing ones 😉 ) There will be more on this soon, once it’s in a stable state.


Rather interestingly, a Brazilian community has recently started developing for the game, and they’re dedicated enough to have already translated parts of the game with the rather shoddy multilingual string support! Full translation of all objects is a little while away though (the IDE will provide this), and sprite font text rendering makes it rather hard to translate into certain languages. We’ll be working on this in the coming months, stay tuned!


To better support the objects and environments present in the original game, we had to switch routing algorithm to one which supported more accurate routing without incurring a huge cost. This combination of a rectangular cover algorithm and A* is performant, fit for purpose and seems to be quite similar to the way the original game does things.

As well as this, a large number of related changes have been made to routing, as well as smaller changes to SimAntics which fix objects such as the Whacketball set, computers and job carpool. Things should generally look smoother and work a little better, but I encourage users to look for regressions and bugs in the new code that I haven’t found on my own!

Of course, the branch contains a lot of extra changes too. For more information check the development roadmap thread on the forums and the pull request on GitHub.


Hopefully this was worth the wait!
