Command Blocker (Lgiws Core)
by Veystreks
Command Blocker, from the author Veystreks, stops command blocks from running commands sent through player chat, so commands are entered another way.
What it does
The mod blocks the use of command blocks through chat messages. Players who try to run commands this way are stopped, which the author describes as a way to keep map creators from having commands used as a cheat or a shortcut when a map is meant to be played as built. It is a client-side mod, so only the player's client needs it. Files are published for Forge only, for 1.12.2, with 1.0.0 as the latest file from 2025-05-22. The code is under the Creative Commons Attribution Non Commercial 4.0 license and is not open source.
