Pistorder
Players who build piston machines can right-click a piston base with an empty hand to preview how the piston will move blocks before it fires.
What it does
Right-clicking a piston base with an empty hand displays what the piston would do if it pushed or retracted. Sneaking while clicking does nothing. The display shows whether the action will succeed, marked with a check or a cross, along with how many blocks would move, including counts above the normal push limit up to a maximum of 128 blocks.
The overlay also lists the order in which blocks would be pushed and the order in which blocks would be destroyed. If the piston fails because of an immovable block, the information may be inaccurate, though it still appears. When an air gap separates the piston from a block, a second click switches to indirect mode, which assumes the piston is acting on that block. The clear hotkey, p by default, removes all displayed information.
Pistorder is a Fabric mod for Minecraft 1.14.4 – 26.2 and is released under the GNU Lesser General Public License v3.0 only, so the code is open source. It is client-side only, meaning only the client needs it and servers run without it. The mod works alongside Fabric Carpet and Quick Carpet for modified piston push limits.
Key features
Push success indicator
A check or cross beside the piston shows whether the push or retract action will succeed.
Block count with extended limit
The number of blocks that would move is displayed, up to 128 even when that exceeds the normal push limit.
Push order display
The blocks to be moved are shown in the order the piston would push them.
Destruction order display
The blocks that would be destroyed are shown in the order they would be broken.
Indirect mode
A second click across an air gap assumes the piston acts on the block beyond it and shows the related information.

Use cases
Building contraptions
Players check whether a piston arrangement will move the blocks they expect before building the rest of a machine.
Debugging piston failures
Players see why a push fails, such as an immovable block in the path, while testing a design.
Who it’s for: Redstone builders and players who design piston machines, contraptions or block movement setups in single-player or on multiplayer servers.
How it compares
Piston Pro Plus is open source under the GNU General Public License v3.0 or later and runs on the client and server for 1.20.1 – 1.21.4. Dynamic Piston Volume is also open source under the GNU General Public License v3.0 only and is for Fabric and Forge on 1.20.1 – 1.21.1, with the client or server optional. Pistorder differs by being client-side only on Fabric alone, and it covers a wider version range up to 26.2.
