FluffSim Wiring Guide

So, you want to try your hand at some Mechanical work in FluffSim but don't quite know where to begin?

Start here then.

This hand-written guide will hopefully tell you everything you need to know about how
to get started using Mechanical Mode in FluffSim.

Getting Started

Gotta start somewhere, amirite?

So, what is this "Mechanical Mode"?
Well, Mechanical Mode allows you to create complex creations in a similar matter to Minecraft's "Redstone" or Terraria's "Wire" lets you do. By placing mechanical pieces together, like a homemade puzzle, you can create things like various fluffy traps, automated machinery, or even something like a full scale pinball machine. However, the process of wiring is nothing to scoff at, provided you're not very experienced in something similar like the aforementioned Minecraft Redstone or Terraria Wiring.

Item Categories

Inputs are the pieces like buttons, levers, and sensors. These are what give everything else a source of power, with only one exception being the Inverter Gate, seen below. Most are activated by you right-clicking on them, some are activated by meeting certain conditions.

Outputs are the pieces that make things happen. These are your conveyor belts, pistons, flamethrowers, etc. Basically, they're the pieces that make things happen. Outputs require a link to an Input piece, or a powered Gate piece, in order to function.

Gates are middle-men of wiring. These pieces let you modify how or when Inputs can power Outputs. You can add a delay to when an Output receives the Input's signal, make an Input's signal becomes inverted to make an Output turn off when powered, and more. These are powerful, yet simple in nature.

Placement Mode

Placement is one of the main things you'll be doing when in Mechanical Mode. Placing pieces is simple as clicking with your mouse. Yes, it's that simple. Just choose a piece to place with your scrollwheel and place it with Left Click. If you mess up, you can just right click on your mistake. Want to rotate a piece before placing it? Just press R to rotate the next piece 90 degrees. Placement is easy due to the fact that you can just hold left-click and go nuts with dragging the mouse around.

Remember: Outputs do not start or function upon simply placing them. They require power from an Input or powered Gate. To provide power, the pieces must be linked together in Edit Mode, seen below.

Edit Mode

Edit Mode is Placement Mode's bigger brother. While Placement takes the puzzle pieces out of the box, it's Edit Mode that puts those pieces together. By pressing Q while Mechanical Mode is enabled, you can switch between the two modes on the fly. Right-clicking on an Output or Gate piece will select it, highlighting it in yellow. Left-clicking will deselect any selected pieces. When you have an Output piece selected, you can right-click on either an Input piece or a Gate piece to link the Output to the piece you right-clicked. The bottom-right corner will show how many connections the piece is linked to. If you've selected a Gate piece, you can only link to Input pieces. Output pieces are linked to Gate pieces, not the other way around, after all.

Linking a piece to another simply means you're letting that piece check and see if a signal says it can be turned on, and Gate pieces are more or less just relaying that signal with a minor change, such as a delay, from an Input to an Output or another Gate.

You can also rotate previously placed pieces by selecting them and pressing R. In order to quickly link more than one Output/Gate to a single Input/Gate, link the first piece to the Input/Gate you want, then hold Shift and right-click on all of the other Outputs/Gates you want to quickly link up to that one piece.

Remember! You must Left Click to deselect any selected pieces in Edit Mode in order to select Gates. Right Clicking on a Gate without deselecting will cause the currently selected piece to link to the Gate you right clicked on!


There are indeed a lot.

A table of all of the controls needed to use Mechanical Mode.

Placement Mode
This mode is where you place all of the pieces you wish to use aligned to a grid.
Key/Button Ingame Description Full Description
Left Click "Place Mechanic" Places the currently selected Mechanic piece at where the mouse cursor is.
Right Click "Remove Mechanic" Removes the Mechanical piece that is under the mouse cursor.
Q "Toggle Edit Mode" Switches between placing pieces and editing/linking them.
R "Set Rotation" Rotates the next piece placed by 90 degrees.
Scrollwheel or Page Up/Down "Change Mechanic" Selects a piece from the list of all of the pieces.
M "Toggle Mechanical Mode On/Off" Turns Mechanical Mode on/off.

Edit Mode
This mode is where you edit and link the pieces you've placed.
Key/Button Ingame Description Full Description
Left Click "Deselect" Deselects all selected pieces. Right-click, below, is the main button used to select and edit pieces.
Right Click "Select/Link Mechanic" Selects a piece/links two pieces together.
Q "Placement Mode" Switches between placing pieces and editing/linking them.
R "Set Rotation" Rotates the selected piece by 90 degrees.
SHIFT + Right Click "Quick Link" Links the right-clicked piece to the last Input/Gate that was linked to.
M "Toggle Mechanical Mode On/Off" Turns Mechanical Mode on/off.

List of Pieces

So far, there are 11 items at your disposal!


Icon Name Description
Fluffy Sensor Becomes powered when a fluffy comes near it.
Lever Right-click when not in Mechanical Mode to toggle it on/off.
Button Hold Right-click when not in Mechanical Mode to turn it on. Unpowers when right-click is released or cursor is moved away from the button.


Icon Name Description
Flamethrower Shoots flames out when powered. Flames can light fluffies on fire. Flames can pass through walls, but they do not pass through fluffies.
Shockbox Rapidly flashes when powered. Electrocutes fluffies and makes them spaz around, harming them to the point of death in the process.
Conveyor Belt (Left) When powered, it moves anything on top of it to the left.
Conveyor Belt (Right) When powered, it moves anything on top of it to the right.
Piston Extends forward and pushes any objects away when powered. Can be used to launch objects and fluffies.
Mechanical Door Similar to Build Mode's Doors, it toggles between open and closed when powered, opening when powered, specifically. Opening one door does not open all adjacent doors, however.


Icon Name Description
Delayer Adds a delay to an incoming signal. Hold CTRL and right-click on it to set the delay in frames, with 60 being the default as the game runs at 60 frames-per-second.
Inverter Inverts any incoming signal, the center turning green when it is inverting a signal. Upon linking an Output to it, the inverter powers any linked Outputs and unpowers them when the Inverter receives a power signal.
