Supported versions

The mod works on its own; no other mod is needed (apart from Fabric API on Fabric). Install it on the server and on every client.

Features

✈️ Flight

• Inert, smooth flight: the ship accelerates and turns gently, coasts, and brakes to a hover without input - even after the pilot has left it mid-air
• Third-person chase camera while piloting; look around freely with the mouse
• Glowing engines and ion plumes in the air, silence on the ground
• Drive pods extend automatically in flight and retract after landing
• Edge guidance slides the ship past edges it barely touches - perfect for flying through a stargate

👥 Seven seats

• Pilot in the bow, two seats behind and four in the rear compartment
• The first player to board pilots; when the pilot leaves, the next passenger takes over
• Passengers are protected by the hull, never run out of air underwater, and travel along through portals

🛡️ Shield and cloak

• Shield: a wobbling energy bubble that absorbs all damage as long as there is energy, flashing on hits
• Cloak: invisible to others apart from a faint shimmer, but still solid; mobs lose track of the pilot

🎯 Targeting and drones

• Living entities and other jumpers within 64 blocks are marked (hostiles red, jumpers cyan)
• Cycle targets with Tab, launch homing drones with a left click
• Drones explode on impact (blocks only break with mobGriefing) and never harm the own ship or its crew

⚡ Energy

• Everything runs on energy (Forge Energy / FE): drive, shield, cloak, drones and lights
• An empty ship loses all systems and crashes - keep an eye on the cockpit HUD with charge, consumption and remaining time
• Lightning charges a jumper by 20 %; during thunderstorms a jumper under open sky even attracts lightning

🔧 Hull and hazards

• 240 hull points, no self-repair; a second hostile drone is fatal
• Harmless light bumps and landings, real damage from hard crashes (at most 30 % of the hull per impact)
• Water slowly damages an unshielded ship, lava burns it quickly - the shield protects against both
• When the hull is destroyed, the crew is thrown out and the jumper explodes

📦 Cargo hold and lights

• 54 slots, items close to the hull are picked up automatically
• Headlights that really light up the world around and ahead of the ship

🌀 Portals and stargates

• The jumper travels through Nether/End portals and stargates as one unit: passengers stay seated, cargo, energy and hull are kept, and the ship keeps flying
• Optional support for Just Stargate Mod (Forge 1.20.1), including gates in the same dimension

Blocks

Jumper Charging Pad

A landing pad that charges a landed jumper from all pads below its hull - a bigger landing field charges faster. By default it needs no power at all. It also accepts energy from cables (Forge/NeoForge energy, e.g. Mekanism, Thermal, Immersive Engineering; Team Reborn Energy on Fabric 1.20.1) and then charges at the full rate. A comparator reads the charge of the jumper on the pad.

Jumper Projector

Builds a new jumper on top of itself after a redstone pulse. The unfinished ship appears as a glowing hologram with sparks scanning the hull and is finished after 10 minutes. By default it needs no power.

Getting started

• Creative: Tools & Utilities tab: Puddle Jumper, Jumper Charging Pad, Jumper Projector
• Survival: craft the Jumper Charging Pad (8 emeralds around a redstone dust) and the Jumper Projector (the same, with diamonds in the 4 corners), then let the projector build your first jumper
• Use the jumper item on the ground and the ship appears facing your view direction

Controls

All keys can be rebound under Options → Controls → MCPJ.
