Contraption

* Cart Assembler
* Clockwork Bearing
* Bogey
* Elevator Pulley
* Gantry Carriage
* Mechanical Bearing
* Mechanical Piston
* Rope Pulley
* Windmill Bearing

**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

#### 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.
