# Will no longer be updated after the last version
I wanted to make the mod cause i realy liked the original concept and thought the block could have some use for peoples, but I won't have time to fix/update more.
# Create: Linear Motion Simulated
**Create: Linear Motion Simulated** is an addon for **Create** and **Create: Simulated** that introduces a new linear motion component: the **Pneumatic Cylinder**.
The goal of this mod is to bring a compact, Create-style piston system designed around rotational power, redstone control, multiblock length, and simulated contraption movement.
> Build longer. Push farther. Move structures with Create-style linear motion.

## Pneumatic Cylinder
The Pneumatic Cylinder is a directional multiblock component that converts Create rotational power into linear extension.
A cylinder can be extended by placing multiple cylinder blocks in a straight line. The longer the cylinder body is, the farther its piston head can travel.
### Main behavior
- Forms a **1x1xN multiblock** cylinder body.
- Can face in any direction.
- Receives Create rotational power from the rear side.
- Activates with redstone.
- Extends and retracts a piston head.
- Maximum extension distance depends on the cylinder length.
- Designed to interact with simulated moving structures.
---
## How it works
The cylinder has two important sides:
### Rear side
The rear side is where rotational power is accepted.
For small 1x1 cylinders, the input shaft is placed on the back of the multiblock.
### Front side
The front side is the piston head side.
When activated, the cylinder assembles its moving head and extends it forward. Blocks attached to the head can be moved as part of a simulated structure.
---
## Usage overview
1. Place a Pneumatic Cylinder block.
2. Extend it by placing more cylinder blocks in the same line.
3. Power the rear side with Create rotational force.
4. Apply a redstone signal.
5. The piston head assembles and extends.
6. Remove the signal to retract.
The extension speed scales with rotational speed.

## Create integration
Create: Linear Motion Simulated is designed to feel like a natural extension of Create’s kinetic system.
The Pneumatic Cylinder uses rotational input and redstone control, making it suitable for compact mechanical builds, moving assemblies, doors, platforms, machines, and experimental simulated contraptions.
---
## Ponder support
The mod includes in-game Ponder tutorials to explain:
- how to place the Pneumatic Cylinder,
- how to extend the multiblock body,
- where to provide rotational input,
- how redstone activation works,
- and how the piston head behaves.
Hold the Ponder key on the Pneumatic Cylinder item to view the tutorial in-game.

## Dependencies
This mod requires:
- **Minecraft 1.21.1**
- **NeoForge**
- **[Sable](https://modrinth.com/mod/sable)**

- **Create: Simulated / [Create Aeronautics bundle](https://modrinth.com/mod/create-aeronautics)**
Make sure all required dependencies match the version listed for the mod release.

## Current content
- Pneumatic Cylinder block
- In-game Ponder tutorials
More linear motion components may be added in the future.
---
## Planned content
- An unlocked mode for the Pneumatic Cylinder : By default it will be in unlocked and using the wrench on it will make it switch to the current behavior. The unlocked variant will be free to move via external forces (gravity, properler...). This will be done once Sable update the constraint system.
- A Hydraulic Cylinder block : works the same as the Pneumatic cylinder block but with an external controller (not binded to the same sub level) with length controle using redstone power strengh.
- A springloaded piston Block : A variant of the Hydraulic Cylinder block that would be in a uncompressed state when placed and can be compressed with rotation (and a lot of Stress Unit) and released in an instant (because it's a spring).

## Notes
This project is still evolving. Some behavior may change as Create: Simulated, Sable, and the physics systems around them continue to develop.
If you encounter issues, please report them with:
- Minecraft version
- NeoForge version
- Create version
- Create: Simulated / Aeronautics version
- Sable version
- crash log or latest.log
- steps to reproduce the issue
