PistonProPlus
Make Piston Great Again.
 
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). |

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
