Contraption

Contraptions are Entities that appear as customizable moving structures.

Obtaining

Contraptions can be made by using Movement Anchors such as:

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

Usage

Creation

Assembly and Disassembly

Contraptions are created when a Movement Anchor is activated and the attached blocks are assembled into a Contraption. Most Movement Anchors will activate when given Rotational Force and disassemble back into blocks when not receiving power or when the Contraption is unable to move. Others are activated manually or by Redstone. Most anchors have Movement Modes that change the conditions for when they disassemble.

Attaching Blocks

Each Movement Anchor has at least one sticky side and can move at least one block with no extra utilities. Multiple blocks can be moved with the use of Block Attachment Utilities such as:

•  Linear Chassis
•  Radial Chassis
•  Super Glue
•  Sticker
•  Slime Block
•  Honey Block

Blocks that attach to other blocks, such as Levers, Signs, or Torches, will automatically become part of the Contraption. Blocks that automatically attach to other blocks of the same type, such as Sails, Piston Extension Poles, Mechanical Belts, and Gantry Shafts, only need to be glued in one place.

Blocks can stick to sticky chassis, but chassis won't stick to blocks on their own. Slime Blocks on Contraptions will not pick up Honey Blocks and vice versa, and neither will pick up Glazed Terracotta. They will still pick up other blocks such as Furnaces.

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.

Unmovable Blocks

Certain blocks cannot be moved by Contraptions by default. Other blocks can be moved, but when on Minecart Contraptions, the cart cannot be picked up with a Wrench. For certain blocks, this is adjustable in the config. Movement Anchors are also unmovable while they are active.

Movement Modes

Most Movement Anchors have movement modes that can be changed through their Value Settings Screen by hovering over their side and holding right-click to access the interface. 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. Trains, Cart Assembler Contraptions, Elevator Pulleys, 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	Can be Enabled/Disabled by Contraption Controls
Andesite Funnel  Brass Funnel	Extracts items from the contraption inventory. Set to insert, will pick up items it collides with.	Yes
Contraption Controls	Can be right-clicked to enable or disable other contraption actors	No
Chest  Barrel  Shulker Box  Item Vault  Creative Crate	Blocks that serve as Contraption inventories. Other inventories will be saved, but Deployers, Portable Storage Interfaces, and Funnels will not recognize any other inventories. Each individual inventory can be accessed via right-click while the Contraption is still assembled.	No
Basin	When a Basin on a Contraption is turned upside down, it dumps out the item contents of the basin.	No
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. On Trains, the bell will ring shortly before the train arrives at a station after traveling a distance.	Yes
Blaze Burner	Emits smoke particles. The Burner's head follows the nearest player. When used on a Train in front of Train Controls, can follow a Train Schedule that is used on it.	No
Campfire	Emits smoke particles.	Yes
Deployer	Simulates right or left click actions. If unfiltered, will use the first item it finds in the contraption's inventory.	Yes
Dispenser  Dropper	Dispenses or drops items stored in them. Fire rate depends on the speed of the contraption. If at the center, it fires every second without requiring movement.	Yes
Door  Trapdoor  Lever	Can be interacted with to change its state. Will not update Redstone while the contraption is active.	No
Fluid Tank  Creative Fluid Tank	Serve as fluid Contraption inventories recognized by the Portable Fluid Interface.	No
Framed Glass Door  Train Door  Andesite Door  Copper Door  Brass Door	Automatically opens and closes when a Contraption starts or stops, respectively. Interactable.	Yes
Ice  Packed Ice  Blue Ice	Remains slippery on an active contraption.	No
Ladder  Andesite Ladder  Copper Ladder  Brass Ladder	Climbable on contraptions.	No
Mechanical Drill  Mechanical Saw	Destroys appropriate blocks and damages entities depending on Contraption speed.	Yes
Mechanical Bearing	Anything attached to a secondary Bearing will keep one orientation as the rest of the Contraption moves.	No
Mechanical Harvester	Destroys appropriate blocks, does not damage entities.	Yes
Mechanical Plough	Tills dirt, destroys appropriate blocks, can fling entities without damaging them.	Yes
Mechanical Roller	Clears and paves blocks.	Yes
Note Block	Can be used as an arrival sound cue on Trains. The instrument and pitch is accounted for.	No
Portable Storage Interface  Portable Fluid Interface	Can link to a stationary Fluid or Storage Interface within range and transfer the appropriate inventory.	Yes
Redstone Contact	When the active end of the contact meets that of a stationary Redstone Contact, it causes the stationary contact to emit a redstone signal.	Yes
Seat	Carries mobs or players.	No
Slime Block	Remains bouncy on an active contraption, but does not negate fall damage.	No
Steam Whistle	Can be used as an arrival sound cue on Trains. Pitch is accounted for. On Trains, the whistle can be blown manually via the Train Controls by pressing the sprint key.	No
Train Controls	When used on a Train, can be right clicked to be given control of the Train, or placed in front of a Blaze Burner or Seat to be piloted by the burner or a seated mob.	No

History

Version	Changes
Version 0.5.1:	Added Elevator Pulley Inventories recognized as Contraption Inventories can now be accessed individually while Contraptions are assembled.
Version 0.5:	Ladders on Contraptions can now be climbed.
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.
