Contraption

Contraptions are customizable moving structures.

Obtaining

Contraptions can be made by using contraption controllers such as:

•  Mechanical Piston
•  Cart Assembler
•  Gantry Carriage
•  Mechanical Bearing
  •  Windmill Bearing
  •  Clockwork Bearing
•  Rope Pulley

Usage

A minecart contraption with a Mechanical Bearing.

Multiple blocks can be moved with the use of Linear Chassis, Radial Chassis, Super Glue, Slime Blocks, or Honey Blocks. Blocks that attach to other blocks, such as Levers, Sails, or Torches, will automatically become part of the Contraption.

A Mechanical Bearing can be added to a Contraption to attach a second Contraption that keeps one alignment as the structure moves. It can be attached at any orientation.

Movement Modes

Most Contraption anchors have movement modes that can be changed by hovering over them with a Wrench and scrolling. Most anchors include "Always place when stopped," "Only place near starting position," and "Only place when anchor is destroyed," determining when the blocks are placed back into the world. Cart Assemblers have "always face movement," "pause actors while rotating," and "lock rotation."

Collision

Gantry Carriages, Rope Pulleys, and Mechanical Pistons will stop moving if an unmovable block or set of blocks is in their path. Cart Assembler Contraptions and Bearings will only collide with blocks if the appropriate world interaction block makes the collision.

Entities will also collide with Contraptions.

Contraption Actors

Blocks that have special functions on Contraptions.

Block	Effect
Chest  Barrel  Shulker Box  Item Vault  Creative Crate	Serve as Contraption inventories. Other inventories will be saved, but Deployers, Portable Storage Interfaces, and Funnels will not recognize any other inventories by default.
Fluid Tank  Creative Fluid Tank	Serve as fluid Contraption inventories recognized by the Portable Fluid Interface.
Portable Storage Interface,  Portable Fluid Interface	Can link to a stationary Fluid or Storage Interface within range and transfer the appropriate inventory.
Seat	Carries mobs or players.
Deployer	Simulates right or left click actions. If unfiltered, will use the first item it finds in the contraption's inventory.
Mechanical Saw  Mechanical Drill	Destroys appropriate blocks and damages entities depending on Contraption speed.
Mechanical Harvester	Destroys appropriate blocks, does not damage entities.
Mechanical Plough	Tills dirt, destroys appropriate blocks, can fling entities without damaging them.
Dispenser  Dropper	Dispenses or drops items stored in them.
Andesite Funnel  Brass Funnel	Extracts items from the contraption inventory. Set to insert, will pick up items it collides with.
Door  Trapdoor  Lever	Can be interacted with to change it's state. Will not update Redstone while the contraption is active.
Bell  Peculiar Bell  Haunted Bell	Rings each time the contraption's momentum changes. Haunted Bells will highlight areas where mobs can spawn when this happens. Placed in the center of a Bearing contraption, it will toll for every full rotation. In the center of a Minecart Contraption, it will toll every time the Cart starts or stops. To the left or right, it tolls for every left or right turn, respectively.
Ice  Packed Ice  Blue Ice	Remains slippery on an active contraption.
Slime Block	Remains bouncy on an active contraption, but does not negate fall damage.
Honey Block	Remains sticky on an active contraption.
Campfire	Emits smoke particles.

History

Version	Changes
Version 0.3.2:	Obsidian can no longer be moved by Contraptions. Doors and Trapdoors on Contraptions can now be interacted with.
Version 0.3.1:	Slime Blocks on moving contraptions are now bouncy. Ice Blocks on moving Contraptions are now slippery. Deployers can use Schematics to place blocks accordingly.
Version 0.3:	Added Contraptions mounted between two minecarts. Dispensers, droppers, and bells now work on contraptions. Mechanical Bearings stabilize the rotation of another contraption on a contraption.
Version 0.2:	Contraptions stall when performing certain actions. Contraptions automatically fill their inventories with outputs from world-interaction blocks.
Version 0.1:	Added.
