LPCTools

A client-side Fabric mod that adds a bundle of optional, toggleable tools, tweaks and a small visual scripting system — mostly aimed at technical survival, large-scale building / digging / draining, and item & material logistics.

Every tool is off by default: each one has its own entry, its own toggle and its own hotkey, all managed in the in-game config GUI (default hotkey Z+C, also reachable from Mod Menu).

Requirements

Optional integrations:

• MiniHUD — shapes (regions) for the per-tool work range restriction.
• Litematica — schematics and their render range for the same restriction, the Tiling Tool's selection corners, and the Litematica Material Collector's material list.
• Tweakeroo — LPCfy Tweakeroo List rewrites some of Tweakeroo's lists into LPCTools' own editable config style.
• Mod Menu — config screen entry point.
• LPCCarpetAddition — when its /qsetblock and /qtp commands are available, the matching LPCTools features use them instead of /setblock and /tp so they don't spam chat.

Tools

A Disable All button on the Tools page turns every tool off in one click.

Tweaks

Scripts

A visual scripting system for whatever the tools do not cover. A script is built from a trigger plus a list of operations in an in-game editor (drag to reorder, copy, paste, insert, remove), and stored as JSON in the LPCScripts/ directory.

Triggers:

• Hotkey — a Malilib hotkey.
• Client Tick Start / Client Tick End — runs on every client tick.

Operations cover control flow (Run If Else, While / Do-While / For loops, Iterate Array / Iterate Iterable, Break / Continue / Return), variables (local, per-script static and global static), and value suppliers for block positions, block states and block properties, items and item stacks, entities and players, tag keys, maths and client messages, among others.

Shared Settings

These apply to LPCTools as a whole rather than to a single tool:

• Independent Thread Pool — runs tool work on a separate thread pool (size configurable) instead of the main thread.
• Limit Operation Speed — a global operations-per-tick budget, with separate costs for block interaction, block breaking, entity interaction and entity attacks, to avoid being kicked by servers.
• Bypass Mode — how the client judges its own operations: rotation speed limit sent per tick, and whether block break / block interact / block place / entity interact / entity attack use distance only, a ray cast direction check, or a ray cast only.
• Has Command Method — how LPCTools decides whether you have a command available: the command tree, or gamemaster permission.
• Max Command Length — upper bound for the commands LPCTools sends.
• Max Updates Per Frame — caps per-frame shape updates of the rendering tools.
• Reach Distance / Offhand Operation — per tool: client-side reach, and using the offhand.
• Work range restriction — a per-tool entry (limitWorkingRange) that reads MiniHUD shapes and Litematica schematics: only regions whose names carry the configured prefix are counted, and each one is folded into the allowed area with a mode — + add, - subtract, +~ add the area outside the shape, -~ keep only the overlap.

Notes

• Client-side only: nothing needs to be installed on the server.
• Features that use commands (/setblock, /tp) need the matching permission on the server, and are skipped with a warning otherwise.
• Config is stored next to Malilib's other configs as lpctools-LPCConfig.json; scripts are separate JSON files in LPCScripts/.
• Some tools (Slight X-Ray, Bedrock Breaker, Trade Reroller, …) are helpers for servers that allow auxiliary tools. Follow the rules of the server you play on.
