Stormworks: Build and Rescue News

Fix - Resolved ship buoyancy and other gravity issues

Dear Stormworkers,

The Stormworks: Space DLC is out now!

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

What is included?

This new expansion means that you can build working space rockets, travel to space and the moon, operate in low and zero gravity, build orbital space stations and satellites, perform space rescues, and more.

The moon is the biggest land location yet, with over 1000 square kilometres of lunar surface. Expect craters, caves, stranded astronauts, and damaged space bases.

Create your electrolysis plant to make liquid rocket fuel to burn in your new liquid fuel engines.

Use compressed gas in your RCS system and use your reaction wheels for precise position and orientation control in space, for example when docking with other vehicles or stations.

New missions occur in space and on the moon, including astronaut rescues, repair, and recovery operations.

Design life support systems, considering temperature, pressure, and oxygen / carbon dioxide levels. Equip space suits to protect from the vacuum of space, and build EVA backpacks to assist with space walks.



New Updates To The Base Game

While the Space DLC is required to leave the atmosphere, many changes are included in the base game to ensure workshop compatibility.

The fluid system is completely reworked to support compressed gasses. Air now consists of it's constituent parts: oxygen, carbon dioxide, nitrogen. Gas pressure introduces many new mechanics such as forces due to equalizing pressures, displacement, and more.

The world now wraps around at borders, allowing you to circumnavigate the world of Stormworks.

Many new components are also being introduced including new fluid parts, large solar panels, navigation sensors, directional communication dishes, and more.



A Big Thankyou to the Community

Many of you have helped inspire and drive this new update. Thank you to all the creators who have dared to dream of space and uploaded some incredible space vehicle creations to the workshop. And thank you to the Youtubers who have been showcasing these creations, playing with the idea, and discussing space in Stormworks.

We can't wait to hear what you think of the new update!

Much love
The Stormworks Developers

Dev Notes and Tips:

Tip - Be careful when opening doors between differently pressurized areas...you may find yourself flung out into space!
Tip - DLC owners get the new Stormworks theme space remix as the default main menu music
Tip - Many earthly positional data components don't work in space, make sure you are prepared to navigate manually or with an astronomy sensor
Tip - Components that rely on air/oxygen will be much less effective at higher altitudes as the atmosphere thins
Tip - Characters and creatures need oxygen to breathe, don't trap yourself in a small box with no ventilation
Tip - The fire extinguisher can be used to propel yourself in space!

Dear Stormworkers,

The new Stormworks: Space DLC will release on 12th October!

With just a few days to go, lets discuss some new mechanics!

Fuel Efficiency

Getting to space in the real world is a big challenge. That energy comes from fuel, and it takes a lot of energy to lift fuel into the sky. Often staging is used to jettison spent fuel containers, to reduce weight and improve aerodynamics. Otherwise, a careful and calculated balance is found between the weight of a fuel and the rate of burn.

The same is true in Stormworks. Getting into orbit requires a balanced design, with the correct amount of fuel and engines. Often you don't just want to get into orbit, but deliver a payload like a satellite or part of a space station, so more efficient designs are preferred. If you are playing career, then fuel is a valuable resource that you will need to manufacture.



Resources in Space

Just like in real life, it is expensive to move materials into space. This is significant, as liquid fuels are important for navigating in space, and compressed gasses are important for life support, and RCS manoeuvres. Solar has an initial cost in terms of transport, but will renew electrical power indefinitely, which is useful for heating and reaction wheel control.

Speed and Efficiency

We are introducing a soft speed limit, which is quite common for space games. The limit is set at 500m/s, and while it is possible to go faster than this, it is inefficient in terms of fuel. It is difficult to hit this speed limit when in the atmosphere due to air resistance, but once in space, this limit has a greater effect.



Creative Tools

There are no workbenches in space, but when teleport is enabled, it is possible to teleport anywhere on the moon from the map. It is also possible to spawn creations using the addon editor, in the usual way, as the moon tiles are available.

There are only a few days left! Join us for the launch next week.

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.

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

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.

Much love
The Stormworks Developers
