PistonProPlus

Make Piston Great Again.

License: GPLv3 Minecraft Mod Loader Java

A server-side Fabric mod for Minecraft 1.20.1 that enhances piston behavior with configurable push limits, advanced block pushing control, and NBT data preservation.

Features

  • Configurable Push Limit -- Break the vanilla 12-block restriction, set any limit from 1 to 4096
  • Infinite Push Mode -- Set the limit to a negative value to enable virtually unlimited pushing
  • Type-Based Block Control -- Individually toggle whether command blocks and all other blocks can be pushed
  • NBT Preservation -- Block entity data (e.g. command block commands) is retained through piston pushes
  • Hot-Reload -- Change configuration on the fly with /pistonproplus reload, no restart needed
  • Full i18n -- English and Chinese built-in; easy to extend

Commands

Push Limit

Command Permission Description
/pistonproplus pushlimit set <limit> OP (level 4) Set piston push limit (1-4096). Use -1 for infinite mode.
/pistonproplus pushlimit get None Display the current push limit and mode.

Type Limit

Command Permission Description
/pistonproplus typelimit commandblock [true/false] OP (level 4) Toggle or query command block pushing.
/pistonproplus typelimit all [true/false] OP (level 4) Toggle or query all-blocks pushing (except MOVING_PISTON and command blocks).

Omitting the boolean argument displays the current status (ON/OFF).

Utility

Command Permission Description
/pistonproplus help None Show the help menu.
/pistonproplus reload OP (level 2) Hot-reload configuration from disk.

Configuration

Settings are stored in config/pistonproplus.json and can be edited directly or via commands.

{
  "maxPushLimit": 12,
  "allowInfinitePush": false,
  "allowPushCommandBlock": false,
  "allowPushAllBlocks": false
}
Key Type Default Description
maxPushLimit int 12 Maximum blocks a piston can push (1-4096)
allowInfinitePush boolean false When true, push limit becomes 4096
allowPushCommandBlock boolean false Allow pistons to push command blocks (NBT preserved)
allowPushAllBlocks boolean false Allow pistons to push nearly all blocks (except MOVING_PISTON)

Warnings

  • MOVING_PISTON (block 36) can never be pushed. This is a hard safety constraint.
  • Command blocks may lose NBT data in edge cases; the mod preserves NBT through capture/restore, but complex setups should be tested.
  • Pushing all blocks may cause unexpected behavior. Attached blocks (redstone dust, torches, etc.) on slime blocks can behave unexpectedly during large pushes.
  • Very high push limits may cause server lag. Test incrementally before deploying on production servers.

Requirements

  • Minecraft 1.20.1
  • Fabric Loader >= 0.18.4
  • Fabric API
  • Java 17+
