Stormworks: Build and Rescue News

Dear Stormworkers,

It is update week! Please see below for the patch notes for this minor update.

The change list may be small this week, but all changes are in a positive direction. We are particularly busy with final testing of Space DLC, and we are very excited for the release in less than 2 weeks!



Next week we will return with a final announcement and discussion on the upcoming release, and then on Thursday 12th October, the Space DLC will launch.

Much love
The Stormworks Developers

Dear Stormworkers,

In this weeks announcement post, we discuss some of the new systems, and explain what to expect in the upcoming Space DLC, with regard to the mechanics of orbit and travelling to the Moon.

Stormworks Space DLC releases on the 12th October.

As previously discussed, space in Stormworks will not be a true planetary body simulation. There are apparent limitations - the moon is in a fixed position directly above in the sky, and the world is a wrapping grid rather than a spherical wrapping one.

So, Stormworks: Space is just a new moon island high in the sky then? Well, no, and there are some cool new systems which model gravity, orbits, and planetary bodies which results in a simulation that appears to observe many of the rules and effects of physics found in planetary body simulations:

Gravity

Gravity in Stormworks: Space is derived from the distance to the earth and moon. The pull of gravity fades with distance with a physically accurate equation.



Elliptical Orbits

As the earth rotates, there is a centrifugal effect - objects would travel in a straight line except for the effect of gravity accelerating their path towards the centre of the earth, and thus curving their path. This acceleration due to gravity is constant. Motion in the horizontal plane is actually moving away from the centre of the earth very slightly, and as this horizontal motion increases, the acceleration away from the centre of the earth increases. This acts in the opposite direction to gravity.

The vertical acceleration due to horizontal motion is inversely proportional to the distance from the centre of the earth, so as you travel higher, there is less acceleration. This effect introduces elliptical orbits. To achieve a circular orbit, of constant altitude, you must have equal force due to gravity and horizontal velocity, and also have zero vertical velocity, at the same time.



Planetary Body Rotation

The earth rotates one revolution every day. As you launch from the surface, you launch with the horizontal velocity due to this rotation. This also means that to remain at a fixed position above the ground, you must also be travelling horizontally so that one revolution is also made every day. At around 300km above the surface of the earth, this velocity balances out the effect of gravity, achieving geostationary orbit.



Navigation

We are adding a new astronomy sensor that provides coordinates that better explain your location in space. The area between the earth and moon is mapped. Some navigation type sensors don't work in space such as GPS, which will stop working at a certain altitude, similar to the real world. The coordinate systems provided by the astronomy sensor are much more useful for understanding your position relative to the earth and moon.

As discussed, we are introducing world-wrapping at the same time as the Space DLC releases, meaning travelling across the edge of the map will wrap you back around on both the earth and the moon. This applies to quite a high altitude, but as you get deeper into space, the world will no longer wrap and you can travel infinitely.

We can't wait to share this new update! We look forward to your thoughts and feedback on these new systems.

Dear Stormworkers,

This week we are releasing a minor update focused on fixes and features. Please see the change notes below for info on what has changed.

While the new fixes are relatively minor, we are pleased to be making positive quality changes, and our plan is to focus the minor updates on quality and bugs over the next couple of months.



One issue that players have been experiencing since V1.7.11 is random music or audio playing when Stormworks is running. It appears that Steam may have updated their overlay software, and at least in some situations, any Steam overlay browser will reopen and start playing any audio on that page. If you are experiencing this issue, you can press shift+tab, and close these browser windows.



With just 4 weeks to go until the new Stormworks: Space DLC, we are hard at work with final testing and tuning. We have a minor update planned for 29 September, and then the major update and new DLC arriving 12th October.



Much love
The Stormworks Developers

Dear Stormworkers,

In this announcement post, we will discuss some of the new systems we are creating as part of the Space DLC, and the associated free major update.

Compressed Gasses and Liquids

As previously discussed, compressed gasses are coming to Stormworks, with a significant rework of the fluids system. This has a big impact for space, but also for deep-sea where high pressure and displacement will work slightly differently.



Gasses in the new version are able to enter and occupy compartments, and these gasses are compressible. When liquids and gasses enter or leave a compartment, they are treated as mixed evenly rather than layered by height, for the sake of usability by players, so behaviour is more consistent and it is easier to understand what is going on. This is to avoid the situation where a port on a compartment cannot capture all the contents because the port is part way up the side - its difficult to understand that the fluid level may have dropped below the port. This is also consistent with current behaviour and avoids players vehicles from breaking.



However, when it comes to doors, it is easier to understand where the water levels are relative to the door and is visually explained, so our system is a bit more in-depth. As in the current system, doors will only allow water through when the level of the water is above the bottom of the door. With new gasses, gas can also only spill through then the water level is below the top of the door.

The implications of this is quite exciting. It means that moon pools will mechanically work, and gas will not escape once water covers the door. Don't forget that the gasses are compressible, so water can still rise and compress the gas, it is just that the gas will not escape. You can pump more gas in to increase the pressure, pushing the water level back down.



The opposite is also true. If you open a door in the top of the compartment, this will allow all your compressed gas to escape, reducing the pressure and allowing more water to enter.

For submarines, this system means that you could open valves (or even a door) between a compressed air container and a ballast tank with opening at the bottom. This would rapidly increase pressure, quickly pushing the water out and displacing it with compressed gas.



Where there is a pressure difference through a door, gas or liquid will get pulled through. Physics objects including characters will be effected by this and dragged by the pressure. At high altitude or in space, a rapid depressurization event can suck you or any other physics object out of the door.

We look forward to releasing this new system and many other features, and the new Space DLC on October 12th!

We look forward to your thoughts and feedback.

Much love

Dear Stormworkers,

This week we are releasing a minor update focused on fixes and features. Please see the change notes below for info on what has changed.

Thank you to all who watched the Stormworks: Space live stream! The feedback has been fantastic and we are so excited for the release on October 12th! If you have not done so yet, please consider wishlisting below:

https://store.steampowered.com/app/2383250/

As well as this weeks minor update, there will be 2 more minor updates before the launch of Stormworks: Space! These are scheduled every 2 weeks as normal.

We are working hard on the last few finishing tasks, and have already been testing for months. While the main features are in the DLC, the release will be accompanied by a major update including the gas and liquid reworks as well as others, which will be important updates for everyone.



Thank you to everyone who have helped inspire this new DLC, including all the incredible creators who have shared space content, and content creators who have made space themed content.

As well as work on the new DLC, there is work on several minor updates, major updates, as well as 'Not Stormworks 2'.



As always, we are interested to hear player thoughts, especially as we plan out what next. Please do let us know where you think our priorities should be, and what you would like to see next. If you have detailed proposals, please consider posting a feature request on the issue tracker too :-)

We are excited to do more, and so we are creating 1 or 2 new engineering jobs to expand our team! If you are a software engineer, check out the new careers section of our website.

Much love
The Stormworks Developers
