BlockShips

A Minecraft plugin that lets players create rideable, physics-enabled ships. Build custom ships from blocks or spawn pre-built vessels, then sail the seas or take to the skies. All of this without any client side mods or resource packs!

Features

Ships can include:

• Functional blocks - Crafting tables, anvils, enchanting tables work as normal. (furnaces/brewing stands don't yet work)
• Seats - Stairs for passengers
• Cannons - a dispenser with a block of obsidian behind it will shoot its contents. fire all through the ship menu, or right click on the obsidian to fire.

Cannons Firing	Cannon Menu
	(or, right click obsidian to fire individually)

• Storage - Chests, barrels, dispensers remain accessible
• Lead points - Anything leashed to a fence will stay tied to the ship. You can lead things to the ship while its moving. Prefab ships have a single lead point.

Custom Ships

1. Build a structure from allowed blocks (see or edit this in blocks.yml)

• generally, wood/metal/functional blocks are allowed, while stone/dirt/other natural blocks are not
• light-giving blocks, like glowstone, end rods, and beacons, serve as floatation aids. enough of these, and you get an airship!

1. Craft a "Ship Wheel"
2. Place the wheel on your structure
3. Right-click the wheel to assemble
4. Right-click again to board and steer
5. Right-click the wheel, or sneak right-click, to open menu and disassemble

Prefab Ships

Spawn ready-to-use ships, with customizable banners/colors/wood types:

• Small Ship - Fast, lightweight water vessel
• Large Ship - Larger water vessel with more health
• Small Airship - Floats in the air with vertical controls

Command: /blockships give <small_ship|large_ship|small_airship>

Physics System

• Walk on your ships - Players can walk around on deck while sailing/flying. this is still buggy!
• Buoyancy - Ships float based on block weight and density. this is buggy sometimes!
• Movement - Acceleration, drag, and collision response
• Collision detection - Ships interact with terrain and entities (interacting with other ships is buggy)

Inspiration

This plugin is inspired by mods which also implement rideable ships, as well as plugins which have attempted similar functionality. I made this plugin because I realized that with the addition of display entities, it might be possible to create a better ship plugin than previously possible, but without requiring any client-side mods. No code from any of other project has been used. In particular, this plugin was inspired by:

• Ships and Movecraft plugins
• Archimedes Ships mod
• Eureka Ships / Valkyrian Skies mods
