Galacticraft Boobcat Edition 5.4.16-prealpha

For Minecraft 1.21.1. Available for Fabric and NeoForge.

New Lunar Worm — Lunar Burrower

• Added a segmented lunar creature with detailed armor, glowing accents, and animations for crawling, warning, biting, swallowing, digging, riding, and dancing. Its body follows turns and uneven terrain.
• Wild burrowers inhabit lunar caves and defend their dens. Nearby mining and approaching too closely can provoke them.
• Wild burrowers can grab and swallow players. Sneak during the escape window, or have another player interrupt the attack before the swallow finishes.
• Added placeable Lunar Burrower Eggs with visible hatching stages. Hatchlings grow over time into larger companions.
• Tame a hatchling with Moon Cheese Curd or Moon Cheese Slice. Feeding your companion also heals it and speeds up growth.
• Adult companions can wear a saddle and carry a chest with 27 cargo slots. Ride them, let them follow you, or tell them to sit; saddle and chest equipment are visible on the model.
• Added ridden tunneling: press G to toggle tunneling, look to aim, and move forward to dig. Tunneling respects the mobGriefing game rule and avoids fluids, block entities, and unbreakable blocks.
• Added burrower dens, egg clusters, broken shells, shed-armor scraps, and excavated tailings to lunar exploration.

Spider Queen boss overhaul

• Replaced the boss's visuals with a new model, textures, emissive details, and animations that show its attack windups and recovery.
• Added a pounce attack followed by a ground slam that damages and knocks back nearby players.
• Added visible venom projectiles that settle into poison pools. Standing in a pool poisons and slows players.
• Added a nest-building and healing phase when the Queen reaches half health.
• Added eggs that hatch into spiderlings when the Queen cannot reach its target. Break the eggs before they hatch to prevent reinforcements.
• Spiderlings pursue and attack players, and can burrow through obstructions when their route is blocked. Eggs and spiderlings have their own models, textures, and emissive details.

Lunar caves, discoveries, and resources

• Reworked lunar caves, lava tubes, and impact caverns with larger chambers and more varied underground shapes.
• Added fractured outcrops, wall shelves, fallen roof slabs, ceiling breakdown, scattered fragments, and rubble, including basalt and frosted variants.
• Expanded underground discoveries with abandoned survey beacons, expedition supply caches, seismic installations, collapsed drilling equipment, and marked exploration routes.
• Added helion nodules, helion wall crust, helium-3 vents, ice-bearing breccia, and helium-3 fluid and buckets, with new resource textures and glowing details.

Planetary terrain and rendering

• Expanded Moon terrain with anorthosite, impact breccia, mare regolith, rocky regolith, and vesicular lunar basalt.
• Expanded Mars terrain with basaltic sand, rocky regolith, sedimentary rock, and weathered basalt, with updated surface variation. Terraformers now recognize the new Martian rocky regolith.
• Expanded Mercury terrain with rocky regolith, plains rock, impact breccia, and dark regolith.
• Expanded Venus terrain with plains basalt, flow basalt, tessera rock, and stony regolith.
• Added configurable Moon surface shading and improved compatibility with active shader packs, including planetary sun rendering on the Moon, Mars, Mercury, and Venus.

Buggy and tier 1 rocket

• Overhauled the buggy model and textures while keeping the Galacticraft style. Fenders, dashboard, and structural parts now connect logically to the vehicle.
• Added wheel rotation, steering, suspension movement, and a climbing animation for block-height obstacles. Fixed model texture mapping, including on NeoForge.
• Redesigned the tier 1 rocket with improved modeling and textures, animated landing legs and engine details, and a transparent cockpit window so the pilot is visible.
• Added manual rocket landing on nearby terrain: press V to toggle controlled descent and use WASD to steer.
• Control descent thrust with Space to hover or Shift to cut thrust and descend faster. The rocket HUD displays landing controls and thrust.
• A safe touchdown preserves the rocket, remaining fuel, and cargo so you can take off again. Landing legs deploy during descent and retract for flight.
• Fixed NeoForge landing input handling so steering also works during descent.

Launch controller and Astro Miner

• Added the Launch Controller with launch-pad frequency addresses and destination routing.
• Added automatic launch conditions for unloaded cargo, full cargo, full fuel, immediate departure, timed delays, and redstone signals.
• Corrected Astro Miner docking position and facing, and prevented its turn-clearing behavior from carving blocks while at the base or docking.

Oxygen Compressor and fluid handling

• Combined oxygen compression and decompression in the Oxygen Compressor, with a mode switch in its menu.
• Oxygen tanks are visible on the block, with different appearances for small, medium, and large tanks.
• Added gas-release sound and particle effects when removing a tank after oxygen transfer.
• Updated bundled MachineLib with fluid-transfer rate control and the NeoForge fluid-item slot refresh fix, addressing stale bucket contents after machine transfers.
• Preserved compression as the default for existing Oxygen Compressor saves and corrected oxygen extraction in decompression mode.

Meteor defenses, meteors, and flags

• Updated Radar and Cannon models, textures, and animations.
• Updated falling meteors with new models, animated flame and glow details, and distinct stony, iron, and pallasite textures.
• Improved meteor shower placement, loaded-area checks, and flight timing.
• Added an in-game flag editor with a drawing canvas, dye-color palette, RGB color controls, fill, undo, and saving for space-race flags.

Upgrade notes

• The separate Oxygen Decompressor block has been removed. Use the Oxygen Compressor in decompression mode instead.
• New terrain, cave decorations, and generated discoveries appear in newly generated chunks.
• MachineLib and Dynamic Dimensions are bundled in these builds.
• This remains a prealpha build.

Thanks to oszlek for the compressor redesign and MachineLib fluid-transfer fixes.
