Gyroscope Control Update
This update focuses on onboarding: a new in-game Help window and a fresh tutorial flow make it much easier to learn navigation and ship operations. Along the way we also added gyroscope control, navigation and docking polish, and input improvements so everything feels more reliable. Navigation Tutorial System A new tutorial guides you through the basics of navigation step by step, from understanding the controls to executing your first maneuvers. It is designed to work together with the Help window, so you can jump to deeper explanations when needed. Gyroscope Control & Activity UI Ships now support gyroscope control, including the Supply Ship. The gyroscope is a complete new interior item next to thrusters, and there is already a small version with a bigger one planned later. Gyros are tracked in the Astronomic Force analytics, and there is a new UI element that shows gyroscope activity so you can see when stabilization kicks in. This brings much more predictable rotation behavior during maneuvers and docking. Navigation & Docking Polish Navigation planning and docking got a pass of practical improvements: clearer error reporting in navigation checks, more precise angular-velocity requirements, a new deltaV panel, and better formatted navigation log values. We also improved orbit camera defaults and added a timewarp button for navigation tasks to cut down on waiting. Controls & Options Overhaul Key bindings are now managed through a new input action system with categories, special key support, and better localization (including German keyboard layouts). Shown keys in the UI now reflect the player's actual bindings, making the controls screen finally match what you use in-game. Stability & Visual Tweaks A long list of fixes landed across UI, savegames, and autopilot edge cases. Highlights include improved problem icons on vessel lists, better need indicators, and several crash and exception fixes to keep long sessions stable. New In-Game Help Window The Help window ...Read full article on Community Announcements (KillerJoe)Patch NotesOfficial
Navigation Plan Update
This iteration introduces the Navigation Plan system, enabling autonomous orbital maneuvers like docking, orbit changes, and interplanetary transfers. The crew now handles autopilot selection and maneuver planning autonomously. 🌌 The Navigation Plan System The navigation system has evolved significantly! We've introduced a comprehensive Navigation Plan system that enables your ships to perform complex orbital maneuvers autonomously. You can now dock with other vessels, change orbits, transfer to the moon, or even travel to other planets—all managed automatically through the Navigation Plans. 🔄 Autonomous Task Scheduling The navigation plan contains periodically checking tasks, where the crew will check the vessel's state regarding your navigation plan. During these checks, they handle autopilot setup and monitor for deviations. If they notice significant or complex maneuvers requiring more brain power, they set up Navigation Tasks, such as calculating trajectories for rendezvous with other ships and calculate/schedule Mid-Flight Corrections. This creates a more living, breathing ship where crew members contribute meaningfully to navigation operations, reducing your micromanagement burden while adding strategic depth. 🖥️ Navigation Console Planning is done through new Navigation Console interior items. The astronauts from your crew can perform these tasks there, taking over the complex navigation planning responsibilities. Crew skills and experience will directly impact planning efficiency and maneuver accuracy. 🏛️ Ground Station Support (While It Lasts) Initially, you as the player need to handle the planning yourself. The ground station on Earth provides support for complex navigation tasks, offering expert oversight. However, as the war on Earth intensifies, this support will become unreliable and eventually disappear entirely. Want to see more? I also post the progress and more pictures to our Discord:https://scifanstudios.com/discord And don't forget to wishlist...Read full article on Community Announcements (KillerJoe)Patch NotesOfficial
Supply Ship Update
We’ve completely overhauled the SupplyShip: handling is tighter, stages are fully integrated, and Crew Capsules now manage oxygen and food just like on the main ship. Low-altitude operations are more stable than ever thanks to the new Surface Mode, while the polished time and astronomical systems make every mission precise and reliable.The New Supply ShipThe SupplyShip handling has been completely overhauled. Ships now require an integrated Crew Capsule, which consumes oxygen and food after launch—just like on the main ship. This lays the foundation for future mission updates.Players can now purchase and manage stages, and the ship handles them automatically when needed.StagesStages are fully integrated and automatically triggered during ascent or orbital adjustments. Each stage can include tanks, thrusters, and separators, allowing modular ship design.The “Enable at Stage” system lets components activate automatically at a specific stage.To make mission planning transparent, each stage now displays DeltaV calculations, showing exactly how much maneuvering capability is available. Players can plan precise missions and see the impact of each stage clearly.Surface ModeA new Surface Mode improves low-altitude flight and landing stability. Takeoffs, landings, and close-to-surface maneuvers are now precise, preparing the game for future atmospheric gameplay.Time System & AstronomicsThe time system has been polished and fully synchronized with the astronomical simulation. Fuel consumption is now accurate even at high speeds or accelerated simulation rates.Astronomics can trigger events in the task system, and players can now see which system is currently affecting game time. This makes long missions more predictable and reliable.Credits Over TimeThe player now receives credits over time, providing a clearer feedback loop for ongoing operations. In future updates, credits will also be affected by events and resource trading (e.g., mining Helium3 on the Moon to sell back to...Read full article on Community Announcements (KillerJoe)Patch NotesOfficial
Navigation Update
It’s been a while – the last three months have been quiet in terms of updates. But behind the scenes, we’ve been working on a major feature: Your ships can now move. Really move.In the previous version of Generation Ship, you could build your ship and configure it – but it remained locked in a static orbit. That has changed. Dramatically.🚀 Realistic Spaceflight – Built on Orbital MechanicsThere is now a complete new navigation system, using real orbital physics. Planets and moons now move along proper trajectories. Your ship isn't just a visual object in space – it's a physical entity obeying gravity, inertia, and thrust.Placement of engines, mass distribution, and the center of mass (COM) all matter. Ships with unbalanced designs may spin, drift, or behave unpredictably — just like in real spaceflight.🔧 Engines, Gimbals & Thrust BalancingEach thruster now applies real directional force, and most engines support an adjustable gimbal for steering.To help stabilize things, we’ve introduced an automated thrust balancing system that adjusts outputs across all engines to maintain control, even in asymmetrical designs.The UI now includes a directional control overview, letting you see at a glance how maneuverable your ship is in each axis — ideal for debugging tricky ship layouts.🕹️ Keyboard Control & NavBall Flight InterfaceYou can now pilot your ship directly using keyboard input. To support orientation and spatial awareness, we’ve added a full NavBall UI – showing orientation relative to prograde, retrograde, normal vectors and more.A simple autopilot is also included: stabilize your orientation, point toward targets, or align with maneuver vectors – all at the push of a button.🌌 New Star Map & Maneuver PlanningThe new star map lets you visualize planetary orbits, moon paths, and your own trajectory in real time. You can set maneuver nodes directly on your orbit – tweaking speed and angle to reach your goals.Need help? An early maneuver planner can automatically calcul...Read full article on Community Announcements (KillerJoe)Patch NotesOfficial
Update 0.100 Radiation
We reached version 0.100! A long journey lies behind us, and the game keeps improving. In this iteration, radiation was added as a new gameplay element. Radiation As always, I aimed to use scientifically accurate values. Radiation in space comes mainly from solar activity and cosmic rays. While in Earth's orbit, you're still partially protected by the planet's magnetic field—but that protection is much weaker than on the surface. Once the ship leaves orbit, radiation becomes a much greater threat. {STEAM_CLAN_IMAGE}/40544258/626097f55b6d2d713e918e31f482eb30ba7ca1f1.jpg Radiation Dose Radiation is now measured as a dose per crew member. Higher doses reduce walking and working speed. Very high doses damage health and can eventually lead to death. You'll need to carefully manage exposure to keep your crew safe. {STEAM_CLAN_IMAGE}/40544258/4f93e46873889b388ecb189f41a151e64ddcd291.jpg Protection – Steel There are now different ways to improve radiation protection. One of them is the ship's hull. A second room type is now available, using more resources but offering better passive shielding through improved construction. To support this, the Room Editor received a major overhaul. {STEAM_CLAN_IMAGE}/40544258/dd5404d79a09aba6c0f36a8af7429b46230ff423.jpg Protection – Water Rooms can now include water storage in the hull, providing additional passive shielding. You can install a Water Pump to fill or empty the hull space with water. Water is a highly effective material for blocking space radiation and adds another layer of defense. {STEAM_CLAN_IMAGE}/40544258/4d74aea85990df4a7ea8df22cab0f629bc90d21e.jpg Protection – Magnetic Fields As a high-tech solution, you can build a Magnetic Field Generator. It consumes a lot of energy but provides powerful protection, especially useful during critical radiation events. {STEAM_CLAN_IMAGE}/40544258/3dc979d83324699374650a6218f7164883dccfd8.jpg Sun Eruption The regular radiation level in space is manageable, but there are also solar events...Read full article on Community Announcements (KillerJoe)
