Create: Deep Seas 3.0.0 & Create: High Seas 0.1.1

The biggest update so far. Boats get a mod of their own, ships flood and sink for real, the deep sea can crush your hull, and submarines get a computer, a sonar and an autopilot. The full technical list is in changelog.md. This is the player version.

Read the Heads-up at the bottom before updating. Some old blocks are gone and the config has moved.

⛵ Create: High Seas (new companion mod)

• Living wind: it shifts direction and strength over time, gusts, blows harder in rain and thunderstorms, and is blocked by the terrain around you.
• Sails: a new Sail block in 16 colours (right-click with a dye). Each sail pushes where its canvas faces, so you trim your sails to the wind. You can still beat upwind, just slower.
  • The canvas really billows in the wind, bulging away from it and flipping when the wind changes side.
  • Right-click a sail to roll it up with an animation. A furled sail stops pushing and stops colliding.
  • Sails on a Swivel Bearing push the ship too.
• Realistic speed: a ship's cruising speed grows with its hull length and drops if it carries too little canvas. A rigged raft does about 8 m/s; ships from 13 blocks long reach 14 m/s. Light boats can no longer be launched into a wall.
• Boat Engine:
  • runs on fuel, refuelled from its own menu (lava buckets give the bucket back);
  • has idle and running sounds and exhaust smoke;
  • won't start if its propeller is blocked;
  • from the helm, hold right-click and move the mouse to set the top speed from 0 to 15.
• Helm & Rudder to steer, with a proper seated pose.
• Anchor on a Steel Cable: it hangs light and pins the ship with a full ton once it touches the bottom. The winch gives a redstone signal when the anchor is grounded.
• Oars: rowing with animations, including from a buoy seat.
• Buoys you can sit in.
• Seaglide: an underwater scooter with speed effects and its own sounds.
• Wind Vane: shows the wind. With goggles, it also shows how well your sails are trimmed.
• Its own config screen (wind, sails, engine, oars, seaglide, anchor) and its own section in the Simulated creative tab.

🌊 Floating, flooding and sinking

• Boats float on the water they really displace and keep their holds dry, with the same pixel-perfect water hiding as submarines.
• Progressive flooding: a breach no longer floods a room in one go. Real water pours in block by block, from the lowest point up.
  • The deeper the hole, the faster the water comes in. Several holes flood faster than one.
  • A room with no way out for the air keeps an air pocket that shrinks as you go deeper.
  • When the ship rises, water drains back out through holes that end up above the surface.
  • The water sloshes to the low side when the ship heels.
  • Every block of water weighs the ship down where it sits. A flooded ship lists, settles by the bow and sinks all the way to the sea floor.
  • Only covered parts of the ship fill up. An open deck simply stops floating the ship once the sea reaches it.
  • Open doors, trapdoors and hatches count as holes; closing them seals the room again.
  • Breaches are saved with the world. Repairing the hole seals the room.
• A sealed hull with no running oxygen that ends up underwater fills with water after two seconds.

💥 Pressure and implosions

• Hull strength rebalanced per material:

  Material	Holds to
  Glass	20–30 m
  Wood	about 40 m
  Stone	60–80 m
  Iron	about 100 m
  Ordinary blocks (cap)	400 m
  Obsidian	500 m
  Pressurized glass	700 m (for the Abyss)

• Hull strain: past 80% of your crush depth, the hull creaks and the camera sways gently, more and more as you near the limit.

• Last warning: a hull block about to give way groans, drips, flickers the lights and shakes the camera for three seconds.

• Implosions:

  • Above 120 blocks of depth (changeable in the server config), the block bursts and the room floods through the hole.
  • Deeper, the hull implodes. A deadly shockwave hits everyone inside and hurts everyone nearby, and the ship tears into many pieces under a string of underwater explosions.

• Dying in an implosion: the screen cuts to black and every sound stops. Your ears ring while one of four lines about the depth fades in, then the death screen appears.

• No more fake pressure: pressure only counts real water above the ship, so dry underwater caves are safe.

🖥️ Onboard Computer, Sonar and Autopilot

• Onboard Computer: a chart screen you click directly, with no menu.
  • Type a target depth and pick a speed, and it drives your Pump Controllers by itself.
  • It learns how fast your pumps are, brakes in time and holds the depth to the block.
• Pump Controller: a Create-style pump the computer takes over automatically. It always pumps the right way, whichever way it faces.
• Sonar: a spinning, glowing block that maps the sea floor around the ship as a 3D blueprint, refreshed by a ping every two seconds.
  • Mines, creatures and other ships show up as coloured dots, even behind rocks.
  • It shows your clearance above the sea floor.
  • A large map window lets you pan, rotate and zoom.
• Autopilot: follows the sea floor 4 m above the ground, looking ahead to climb before slopes, and never goes below your crush depth.
• Diagnostic: a full hull report with the maximum safe depth, the weakest block, a HERMETIC/BREACHED stamp, cracks to repair and the coordinates of every leak.

🔧 Blocks and items

• Decompression Chamber (finished): a real airlock you flood and drain with a pump. Pipes now connect at any time. It has a step-by-step Ponder scene.
• Industrial Alarm: red lamp and siren when you dive past your hull's limit. It flashes faster the deeper you go.
• Arresting Hook: mount it under a ship and power it, and it grabs a Steel Cable stretched across your path to brake you to a stop, like a carrier landing. Craftable, with a Ponder scene.
• Big Propeller: four propellers in a 2×2 square merge into one, 16× stronger than a single one.
• Electrolyzer:
  • put a Shaft in its new module slot to run it on rotation;
  • it faces any direction and can be turned with a wrench.
• Ballast Tanks and Ballast Vent:
  • Ballast Tanks connect like Create's tanks and can be placed a whole layer at a time.
  • The Ballast Vent is now a simple sea valve, with a rewritten Ponder scene.
• Other changes:
  • Pulleys can be placed upside down.
  • Mines and Pulleys are now solid.
  • The mine recipe is cheaper.
  • New Oxygen Bucket.
  • Moving ships leave a wake.

🧭 Handling

• Submarines rise and dive straight, level themselves out and turn where their bow points instead of sliding sideways.
• Diffuser air is for breathing only and no longer lifts the hull.
• A submarine over magma no longer drags the people inside down to the floor.

⚡ Performance

• Big ships: they no longer freeze the game when a block breaks. Hull scans are spread out and only run when the hull changes.
• Floaters and Ballast Tanks: they share their group data instead of each one rebuilding it, which makes big arrays much cheaper.
• Boat logic: ships out of the water (airships, ships on land) cost nothing to the boat system.
• Oxygen Diffusers: they only rescan when the hull actually changes.

♿ Accessibility

• Photosensitivity warning on first launch. Tick "I am photosensitive or epileptic" (or photosensitiveMode in the client config) to turn off the alarm's coloured flashing light.
• Server owners can stop alarms from flashing for everyone with alarmSteadyLight.

🛠️ Main fixes

• Water:
  • /sable remove no longer leaves a dry hole in the sea.
  • No more holes in the water around stairs and slabs, and no water showing through slab floors.
• Iris and Sodium:
  • With Iris installed, the Sonar and the Alarm no longer turn the screen black and purple. They give normal Minecraft light instead.
  • Fixed a Sodium crash when another Veil mod is installed.
• Fog: fixed fog in air pockets and with Distant Horizons.
• Ropes and cables:
  • Steel cables no longer fling you, trap you on a block or push you into the floor.
  • A plain rope no longer carries power like a steel cable.
  • Anchors no longer launch the boat when tied.
  • Ropes on anchors and buoys are visible again.
• Ships and sails:
  • Big square-riggers no longer get stuck in place.
  • Sails no longer push players into walls.
  • The Wind Vane no longer points backwards.
• Dupes and exploits: fixed the Diffuser/Electrolyzer duplication. Wrecks no longer chain-explode, and the boat menu closes when you walk away.
• Interface:
  • Clicks on the Onboard Computer screen now land exactly under the crosshair.
  • The helm body no longer jitters.
  • You can no longer take the tiller where there is no room to sit.

⚠️ Heads-up

• Removed: the old Weather Vane and Submarine Rudder disappear from your worlds. Use the High Seas Wind Vane and Rudder.

• Old sails: Simulated's Symmetric Sails no longer push ships. Replace them with the new Sail.

• Config split into common / server / client files. Gameplay values go back to their defaults in the new per-world server config.

• Hull strength: your old default values are updated automatically on first launch. Values you edited yourself are kept, and submarine_hull.json is backed up first.

• Shaders: with an Iris shader pack, sails don't billow, and the Sonar and Alarm have no coloured lights.

• Requires:

  • Create Aeronautics 1.3.2+;
  • Simulated 1.3.0+;
  • Sable 2.0.3+;
  • if you use it, Sodium 0.8.12+.

  Lithostitched and Fusion are now built in.

• Submarine Staff: not in this release yet.

Translations: English and French are complete. Some new texts are still in English in the other languages.
