== Core Features ==
Many machines and components in ''Create'' require [[Rotational power|Rotational Force]] to operate. Rotational force is generated by several [[:Category:Generators|Kinetic Sources]] such as the {{ItemLink|Hand Crank}} and the {{ItemLink|Water Wheel}}. Rotation can then be transmitted to Kinetic Appliances which perform a variety of actions with items such as a {{ItemLink|Crushing Wheel}} or a {{ItemLink|Mechanical Saw}}.
<br />
==='''The Basics of Rotation'''===
[[File:Rotating encased belt.gif|frame|A Rotating Encased belt block|alt=]]


Rotational force has three characteristics: direction (clockwise, counter clockwise), speed in revolutions per minute (rpm), and [[Kinetic Stress]] (or power) measured in Stress Units (SU). Kinetic sources provide a specific number of stress units depending on the configuration of the source. Each kinetic appliance uses a certain number of stress units depending on the type of appliance and rotational speed. When the total number of stress units required by the attached appliances exceeds the number of stress units provided by the kinetic source, the kinetic source stops completely until the required stress units are reduced.


Many machines and components in Create require Rotational Force to operate.
==='''Generating Rotational Force'''===
[[File:Simple Windmill.png|thumb|Simple Windmill]]Main Article: [[:Category:Generators|Generators]]


Any machine/component blocks that involves moving blocks or moving/crafting/converting item or entities (and the Cuckoo clock), will require a certain amount of speed or higher in order to operate.
===Transmitting Rotational Force===
[[File:TransmitPower.png|thumb|360x360px|Transmitting power with shafts, belts, cogs and gearboxes.]]
Rotation can be transmitted in a straight line using a {{ItemLink|Shaft}}, {{ItemLink|Mechanical Belt}}, or {{ItemLink|Encased Chain Drive}}. The direction can be turned 90 degrees using a {{ItemLink|Gearbox}} or {{ItemLink|Large Cogwheel}}. The rotation can be temporarily stopped using a  {{ItemLink|Clutch}} and can be reversed with a  {{ItemLink|Gearshift}}


<br />
The image to the right illustrates rotational power coming in from the top left via a length of connected shafts. The direction is turned 90 degrees downward using two large cogwheels. The vertical shaft then powers a gearbox that turns the direction of rotation to the right where a series of cogwheels, mechanical belts and gearboxes power a {{ItemLink|Deployer}}, a {{ItemLink|Mechanical Press}}, and a {{ItemLink|Mechanical Mixer}}.


==='''Generating and Transferring Rotational Force'''===
These transmission components only transfer, stop, or convert rotational power. They do not consume any power [Unless changed in the [[Configuration|Config]]] or change the speed of rotation.
Components such as shafts, gearboxes, gearshifts, clutches etc only transfer, stop or convert rotation power, and do not have any speed requirement.<br />


==='''Changing Gears'''===
===Changing Speed===
Just alone having components rotate is not enough. Sometimes more control over the speed of rotation is necessary. This is especially important for machines that require a ''minimum level of speed'' to operate (e.g. the Mechanical Mixer). To make this possible, some kinetic blocks have the ability to ''speed up'' or ''slow down'' connected components:

====Adjustable Chain Gearshift====
=== Adjustable Chain Gearshift ===
[[File:Adjustable Chain Drive Example.png|thumb|320x320px|Adjustable chain gearshift doubling the speed of an encased chain.]]
The Adjustable Chain Gearshift, when used in combination with encased chain drives, gives finer control over speed than cogwheels. It can increase ''input'' speed for attached chain drives, or decrease ''output'' speed of shafts connected to chain drives.
The {{ItemLink|Adjustable Chain Gearshift}} when used in combination with {{ItemLink|Encased Chain Drive}}s, gives finer control over speed than cogwheels. It can increase ''input'' speed for attached chain drives, or decrease ''output'' speed of shafts connected to chain drives.
 
While acting as an input, the Adjustable Chain Gearshift will increase the speed of attached encased chain drives based on the analog redstone signal it receives. A full power of 15 will double all chain drives' speed while values below will interpolate the factor from 2x to 1x.


While acting as an output, the Adjustable Chain Gearshift will decrease the speed of connected shaft. A full power of 15 will half the speed and values below will interpolate the factor from 0.5x to 1x.
While acting as an input, the adjustable chain gearshift will increase the speed of attached encased chain drives based on the analog redstone signal it receives. A full power redstone signal of 15 will double the speed of the chain drives while values below 15 will increase the speed proportionally between 1x and 2x. While acting as an output, it will reduce the speed of the chain drive in a similar manner. With no redstone signal, the speed will remain unchanged.


When unpowered, the chain gearshift will not affect the speed at all and behaves like an encased chain drive.
===Rotation Speed Controller===
<br />
While having a more expensive recipe, the {{ItemLink|Rotation Speed Controller}} also has the finest control over speed change. When a large cogwheel is attached to the controllers top, the large cogwheel, or shaft [depending on which one is powered] will spin at the configured speed in the [[Value Settings Screen|Values Settings Screen]].  
 
=== Rotation Speed Controller ===
While having a more expensive recipe, the RSC also has the finest control over speed change. When a large cogwheel is attached to the controllers top, it will try its best to keep it spinning at the speed configured in the scroll field. When holding down ''shift'' while scrolling, the speed will increase/decrease by 1.
<br />
 
=== Overpowering ===
Connecting faster components to other slower components directly will cause the faster network to overpower the rest, aligning the speed of the component network (that is, if the direction lines up).

The Basics of Rotation[edit | edit source]

A Rotating Encased belt block

Many machines and components in Create require Rotational Force to operate. Rotational force is generated by several Kinetic Sources such as the  Hand Crank and the  Water Wheel. Rotation can then be transmitted to Kinetic Appliances which perform a variety of actions with items such as a  Crushing Wheel or a  Mechanical Saw.

Rotational force has three characteristics: direction (clockwise, counter clockwise), speed in revolutions per minute (rpm), and Kinetic Stress (or power) measured in Stress Units (SU). Kinetic sources provide a specific number of stress units depending on the configuration of the source. Each kinetic appliance uses a certain number of stress units depending on the type of appliance and rotational speed. When the total number of stress units required by the attached appliances exceeds the number of stress units provided by the kinetic source, the kinetic source stops completely until the required stress units are reduced.

Transmitting Rotational Force[edit | edit source]

Transmitting power with shafts, belts, cogs and gearboxes.

Rotation can be transmitted in a straight line using a  Shaft,  Mechanical Belt, or  Encased Chain Drive. The direction can be turned 90 degrees using a  Gearbox or  Large Cogwheel. The rotation can be temporarily stopped using a  Clutch and can be reversed with a  Gearshift

The image to the right illustrates rotational power coming in from the top left via a length of connected shafts. The direction is turned 90 degrees downward using two large cogwheels. The vertical shaft then powers a gearbox that turns the direction of rotation to the right where a series of cogwheels, mechanical belts and gearboxes power a  Deployer, a  Mechanical Press, and a  Mechanical Mixer.

These transmission components only transfer, stop, or convert rotational power. They do not consume any power [Unless changed in the Config] or change the speed of rotation.

Changing Speed[edit | edit source]

Just having components rotate is not always enough. Sometimes it is necessary to control the speed of rotation. This is especially important for machines that require a minimum level of speed to operate (e.g. the Mechanical Mixer). To make this possible, some kinetic blocks have the ability to speed up or slow down connected components:

Changing Speed with Cogwheels

Cogwheels[edit | edit source]

Cogwheels are not only useful for relaying rotation, but also serve as a simple way to control the speed. By attaching a large cogwheel diagonally to a regular sized one, one can double/half the speed of the other.

Powering the large cogwheel results in the smaller one turning at double the speed.

Powering the small cogwheel results in the larger one turning at half the speed.

Adjustable Chain Gearshift[edit | edit source]

Adjustable chain gearshift doubling the speed of an encased chain.

The  Adjustable Chain Gearshift when used in combination with  Encased Chain Drives, gives finer control over speed than cogwheels. It can increase input speed for attached chain drives, or decrease output speed of shafts connected to chain drives.

While acting as an input, the adjustable chain gearshift will increase the speed of attached encased chain drives based on the analog redstone signal it receives. A full power redstone signal of 15 will double the speed of the chain drives while values below 15 will increase the speed proportionally between 1x and 2x. While acting as an output, it will reduce the speed of the chain drive in a similar manner. With no redstone signal, the speed will remain unchanged.

Rotation Speed Controller[edit | edit source]

While having a more expensive recipe, the  Rotation Speed Controller also has the finest control over speed change. When a large cogwheel is attached to the controllers top, the large cogwheel, or shaft [depending on which one is powered] will spin at the configured speed in the Values Settings Screen.

Stress Units[edit | edit source]

Most kinetic appliances will consume SU (Stress Units).

Materials[edit | edit source]

Create adds many crafting ingredients for use throughout the mod. While some of them have few uses within Create itself at the moment, they are still handy connection points for pack-makers.

  • Andesite Alloy, used for Andesite Casing and all the low-tier kinetic components.
  • Brass, used in Brass Casing and more advanced kinetic blocks. Entry-point to the logistical components.
  • Copper, generates in the world around surface level. Used for Copper Casing and fluid handling components, and used with Zinc to make Brass.
  • Zinc, generates in the world. Used with Copper to make Brass.

Other Materials[edit | edit source]

Moving Contraptions[edit | edit source]

Create allows you to move and animate block structures of any shape or form. This feature is extremely powerful as it proves useful in the field of automation, transportation and aesthetics.

In order to get the most out of this mechanic, it is helpful to know about the components and interactions involved in creating such structures.

  1. Contraption Controllers
  2. Contraption Assembly and Chassis Blocks
  3. Portable Storage
  4. Portable Actors

Contraption Controllers[edit | edit source]

  • Depending on the use case, different controllers can be used for mounting your structure. Some push, some pull, some rotate and some do it all at once.
  • These blocks have specific spaces where the anchor of the structure needs to be, and some can be configured to react differently to being stopped.

Mechanical Piston[edit | edit source]

Mechanical Pistons are kinetically powered counterparts to Minecraft's Pistons. As such, they can push super glued blocks in front of them, and if sticky, pull them back.

However, Create's pistons do not work on their own. They require Piston Extension Poles added at the back, in order to be able to extend. When given Rotational Force, the piston will extend exactly as far as poles have been added to the back, rather than just 1 block space.

Rope Pulley[edit | edit source]

The Rope Pulley moves attached blocks and structures vertically. Use Linear Chassis, Radial Chassis or Super Glue to move more than a single block.

When powered by kinetics, it will start to move the attached structure. Speed and direction correlate to the incoming Rotation Speed.

Mechanical Bearing[edit | edit source]

The Mechanical Bearing is used for rotating larger structures with rotational force.

When Powered by kinetics, starts rotating the attached blocks.

Use Chassis or Super Glue to move more than a single block. Blocks that attach to other blocks, such as levers, torches, Gantry Shafts or Mechanical Saws will become part of the structure automatically.

Other attached Mechanical Bearings, if facing along the same axis as the original, will keep their alignment as the original rotates: See the GIFs for a visual example.

Clockwork Bearing[edit | edit source]

The Clockwork Bearing is an advanced version of the Mechanical Bearing for rotating up to two clock hands according to the current in-game time.

When powered by kinetics, starts rotating the attached structure towards the current hour. If an independent second structure exists in front of the first one, it will serve as the minute hand.

Cart Assembler[edit | edit source]

When placed on a Rail, the Cart Assembler can assemble and disassemble moving structures onto passing minecarts. Similarly to rotating structures, having a Mechanical Bearing in the structure will cause the attached part to keep the same alignment as the cart moves.

Minecart Contraptions[edit | edit source]

Single Cart contraptions as well as Carriage contraptions can carry items, liquids, or mobs, provided they have the correct storage blocks. They can also use Contrapion Actors such as the Mechanical Saw, Drill, Harvester, Plough or the Portable Storage Interface to interact with the world.

Carriage Contraptions[edit | edit source]

Carriage Contraptions are about the same, except their movement is smoother and thus it is easier to walk or ride on them without falling off. See Trains for further detail.
