SimAirport News

Massive performance gains and a ton more all arrive tonight on the default branch! We are extremely excited to release the update to you tonight as we close out this long cycle. We hope you find the wait to have been well worth it -- improvements abound with nearly every aspect of the gameplay receiving attention along with the true focus, the main event of the cycle, being the long awaited performance optimizations. See below for the full change logs. :)


Check out the latest video: SimAirport - October 2018 Update Video


We will be getting back to more rapid cycles now that we have taken care of the key foundational concerns that had hampered performance. We still have more performance gains ahead, and we'll continue to make incremental strides, but we're really ready to knock out some new content and additional gameplay systems!

Next cycle you will be seeing: Tutorial, Cafe / Retail Overhaul, and Staff Scheduling. As usual we'll slide in a few features, QoL improvements, and fixes too -- but the focus will primarily be on these three areas. You'll be seeing the tutorial hit edge this coming week even! :)

Don't forget the Official SimAirport Roadmap to see the whole picture of what to expect!


We want to extend a special thank you to the players on edge & experimental who have been instrumental to making this cycle a successful one. This was the longest cycle to date, and definitely one of the most challenging; we really appreciate the continued testing, bug reporting, and the overall patience that the community as a whole has & continues to extend to us. Your collective support continues to be incredible and is truly second to none. Thank you!!!

Long time, no see! We are getting anxious (and excited) for the next patch to hit Default, and we thought you might be too! With October rapidly approaching we wanted to take a few minutes to provide you with a brief progress report to update you on the status of the current, and massive, dev cycle -- and provide you with an idea of what you can expect from the upcoming patch, and our plans for the next few updates.


Wow! This cycle has been a long one, the last Default patch was in June, but it's for good reason and we believe the the improvements will have been very well worth the wait! A lot has changed, a whole lot -- here are just a few things that are currently on Edge branch, which will be making their way to the Experimental branch next week, and finally to Default in October. Here are a few highlights:

• BIG Performance Gains
  Edge players are reporting massively improved performance.
  
  
• Luggage Tracking & Mechanics
  Change port types on Hubs, upgrade hubs, and watch each individual piece of luggage during its journey.
  
  
• New Pax Graphics
  Rich new animated agent graphics for a more immersive & less cartoony experience.
  
  
• More Data & Reports - Needs & Timings reports, Perfect Ops breakdown, 6+ new pax/agent overlays, and numerous reporting & data improvements.
  
  
• Bank Loan Overhaul - Completely updated bank loan system with credit ratings, bigger loans, and larger interest ranges for a more realistic fiscal premise.
  
  
• Expand in ALL Directions - By popular demand, you can now buy more land in any direction! Even across the street!
  
  
• A Real Main Menu
  No longer will you be dumped into a default airport when you open the game!
  
  
• Construction Improvements
  Better supply pile positioning, fast inventorying of dismantled objects, lower performance impact.
  
  
• Pax AI Update
  Smarter pax, more maintainable code, and better performing AI.
  
  
• MANY BUG FIXES and LOTS MORE
  Of course we fixed a ton of existing bugs, along with the new ones created along the way. Lots more, too! Check out the Edge change log if you want to see what else we've got for you in the upcoming October patch, or check back here when in drops in a few weeks!
  

We are currently in burn-down mode on this cycle, and we're already starting to look towards the next cycle a bit. We've still got a lot more planned and much of it already in the works -- here are the key items that we you can expect to see in the cycle following the October patch. Be sure to check out the SimAirport Roadmap for the complete view of what's to come though!

Planned for the Next Cycle

• Tutorial. Finished! Will hit Edge same day the October patch ships!
  
• Staff Scheduling. Under way! Hits Edge the first few weeks of cycle.
  
• Cafe Overhaul. Under way! Hits Edge the first few weeks of cycle.
  

As always, plenty more will sneak its way into the next cycle too -- but generally we expect it to be a bit smaller, and more rapid, as we move back towards the rapid & iterative development cycles that you were used to.


We want to extend a huge thank you to the community who continues to support us; especially those of you who are playing SimAirport and providing feedback, bug reports, and save game files to us in the Edge forum on a daily basis -- we truly couldn't do it without you. Our most sincere thanks to you, and to everyone in the community!

In closing, here's a quick screen grab to give you an idea of just how truly MASSIVE an undertaking this cycle has been -- we're as excited as you are to see it hit Default, and we're even more excited to dig back in on the next cycle!

Today is the longest day of the year and we wanted to get a jump on it with a small cleanup patch! The small update being released today makes a few improvements and addresses several notable issues that came to our attention shortly after the June 2018 patch went live.

There won't be an update video since this is a small update following the prior release, however we are going to be trying something new over the next few weeks - we will be doing a bit of live streaming directly from the Steam Store page. We don't have dates/times set in stone yet, but we'll announce it on the forum and on our Twitter as soon as we do! We're still new to the video updates, much less live streams and while developer live-streaming may not be the most entertaining we will certainly try our best to make it a fun experience for everyone that stops by! :)

Thank you to the entire community for your unwavering support and for the awesome level of engagement we see on a daily basis! We hope you all have a fantastic summer!

The Default update is here and this one has in many ways been a long time coming! Aircraft pathfinding, once an ongoing cause of frustration, will no longer cause problems for any of your airports! Accompanying this major milestone are numerous additions and improvements including a new 'Sell Airport' mechanic, connecting flight passengers, AI improvements, and the addition of the Russian language pack. There are a handful of new objects and multiple balance-related changes including several research additions & removals, plus more than 50 bug fixes too!


Watch the SimAirport Update Video - June 2018 Edition for some hands-on insight into the update. You'll also be able to learn more about how the aircraft pathfinding works under the hood and how to use that to your advantage, some initial thoughts on retail/cafes, and what we're planning in the future including further insight and an update on our progress with the latest performance improvements which are coming to Edge soon!


Check out the SimAirport Roadmap any time for the latest updated information about what's coming, and be sure to vote on your favorite items & make comments to provide ideas or details about what you'd like to see in the future! As a high-level summary, we think these three key aspects need the most immediate attention right now -- and numerous system improvements & additions, which we'll then be coming back to, after we get these three addressed:

1. Performance
   
2. Tutorial
   
3. Retail / Cafes
   

We continue working hard to bring you enhancements and additions, fixes and performance improvements, and to continue evolving SimAirport every day.

We couldn't do this without the continued feedback and the unwavering support from you, the players -- the engagement, loyalty, and the patience that we observe from the community on a daily basis is truly second to none.

We can't even begin to tell you how much we appreciate it -- Thank You!

• Fixes zone requirements ‘non-secure area’ inverted formatting
  
• Fixes janitors not finish clearing immediate area when quasi-“nearby” jobs exist above or below them on other floors (could result in throughput degradation)

We are thrilled to bring MULTIPLE FLOORS to you on the general release default branch! Building an airport across 5 different floors is truly a game changer and it brings a completely new & unique gameplay experience to SimAirport.


This single update, known as the Multi-Floors Update, quite literally contains a higher number of features & additions from the "big stuff" category than any update that we've released prior.

Moving walkways are consistently a top request and while it wasn't an easy one to implement, that is indeed what we've done. The ability to build vertically -- to take your airport from the world of constrained simulators, and to instead step into the realm of real-world possibilities -- that has easily been the most desired feature, and one that we've been vocal in our desire to tackle. That's precisely what we've done and we're excited to bring it to you. Tonight we invite you to the next level.

Build your airport with real-world possibilities and reach new heights!


Of course the first question that we hear after releasing any update, including huge updates, is what will be next! It's a great question and it is one that we are excited to answer. We're especially excited to continue our ongoing collaboration with you, the community, and in order to better facilitate that ongoing collaboration we're rolling out a few more new things to make things easier going forward.

• SimAirport Survey - 2018 Edition
  
  If you've been with us since release you may recall that we ran a survey early last year to better understand the community and get a feel for what everyone was looking for out of the experience that is SimAirport. It's back! Similar to the first but updated for relevance. Your feedback is what allows SimAirport to flourish, so please consider taking a few moments to complete the survey. By doing so you'll be playing an integral role guiding the future of SimAirport's development.

• SimAirport Roadmap - Updated & Interactive for 2018
  
  We have historically released a new roadmap every few months, but the document often is quickly and it really doesn't contain everything that we're thinking about or that's on our proverbial 'primary radar'. Tonight, we're including an extra fix -- we're fixing the Roadmap itself!
  
  Official SimAirport Roadmap >>
  
  We will continually keep this roadmap updated, in 2018 and beyond, and we invite you not only to take a look -- but to actively participate as well! You can check out each card, vote on them, read & post comments with your ideas & details, and really get hands-on with the future of SimAirport's development process.
  
  
• Update Video
  
  We just barely had enough time to squeeze the video in this month while sticking to the deployment schedules, burning through bug fixes, preparing the roadmap, attending to our personal schedules (and getting taxes done!) -- it's been a whirlwind as we work to wrap up this monster update. Unfortunately Rob was tied up on the day of video capture, which means that you're stuck with Arthur -- who's been known to be a bit wordy & opinionated -- but the show must go on! Hope you enjoy, and Rob apologizes in advance for not being available to control Arthur's rambling!

• Existing Saves & Backwards Compatibility
  
  This update IS backwards compatible though there are a few things to note when bringing an existing save into this patch. Additional details can be found below, and in the full change log as well.
  
  
  • Gates (XL and L) now require second floor doors; gates from existing saves will work on the first floor however, and can also be one-time transitioned to being second-floor.
    
    
  • Baggage System has changed substantially in the latest version. When loading an existing save, all baggage-related conveyors & objects will be removed upon initial load. For baggage guidance we recommend A-Train's fantastic baggage video. Thank you @A-Train for being such an asset in the community!
    
    
  • Fuel Pipelines have changed only slightly but will also be removed upon loading existing saves. Pipelines now require floor -1.
    

Finally, the juicy details in all of their glory! Below you will find the full patch notes for tonight's update!

Multiple Floors - Core Details



• Adds floor selector on right side of main HUD UI
  
• Default hotkeys are page up/down keys - can change in preferences
  
• Adds new floor transition objects: Escalators & Stairs
  
• Small Aircraft Gate requires a ground-floor door; can also purchase 'Stairs' gate upgrade to make it 2nd-floor accessible instead
  
• Large and XL Gates require 2nd floor door for the jet bridge
  
• Baggage Carousels requires connection from "below" ("same level" and "above" varieties to come soon)
  
• Preliminary luggage movement visuals have been re-added
  
  Note About L/XL Aircraft Gates in Existing Saves
  ALL gates in existing saves will continue to work on the Ground floor. You can make a one-time transition on Large & XL gates from existing saves by selecting the gate and clicking "Set to 2nd Floor". New LG/XL gates built will always require second floor doors and cannot be changed. Small gates require a first floor door (and second floor door when stairs upgrade is present).
