Editing Contraption (section)

==Usage==
===Creation===
====Assembly and Disassembly====
Contraptions are created when a [[:Category:Movement Anchors|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 {{MC|Redstone}}. Most anchors have [[Contraption#Movement Modes|Movement Modes]] that change the conditions for when they disassemble.
====Attaching Blocks====
[[File:Ferris Wheel Mechanic 2.gif|thumb|A [[Mechanical Bearing]] on a [[Mechanical Bearing]] Contraption.]]
[[File:Ferris Cart.gif|thumb|A minecart contraption with a [[Mechanical Bearing]].]]
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 [[:Category:Block Attachment Utility|Block Attachment Utilities]] such as:
*{{ItemLink|Linear Chassis}}
*{{ItemLink|Radial Chassis}}
* {{ItemLink|Super Glue}}
*{{ItemLink|Sticker}}
*{{ItemLink|Slime Block|mc=yes}}
*{{ItemLink|Honey Block|mc=yes}}

Blocks that attach to other blocks, such as {{MC|Lever}}s, {{MC|Sign}}s, or {{MC|Torch}}es, will automatically become part of the Contraption. Blocks that automatically attach to other blocks of the same type, such as [[Sail]]s, [[Piston Extension Pole]]s, [[Mechanical Belt]]s, and [[Gantry Shaft]]s, 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 {{MC|Glazed Terracotta}}. They will still pick up other blocks such as {{MC|Furnace}}s.

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 Contraption]]s, 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 Assembler]]s have "always face movement," "pause actors while rotating," and "lock rotation."

===Collision===
[[Gantry Carriage]]s, [[Rope Pulley]]s, and [[Mechanical Piston]]s will stop moving if an unmovable block or set of blocks is in their path. [[Train]]s, [[Cart Assembler]] Contraptions, [[Elevator Pulley]]s, and [[Bearing]]s 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.
