CMask

by Whirdle

CMask adds client-side block masks to Minecraft, so a player can limit which blocks a WorldEdit-style command affects.

FabricClient-side onlyAll rights reserved1.21.8

What it does

Masks work like those in the WorldEdit client, and the mod is built around the same goal syntax used in WorldEdit and FAWE, with the WorldEdit mask wiki as the reference. Commands such as cmask set and cmask clear control the active mask, and a list of blocks can be written as comma separated entries. Quoted block IDs and block states are not yet supported.

Key features

  1. Client-side masks

    Masks are applied on the player's side, following the behavior of the WorldEdit client.

  2. Set and clear commands

    The cmask set and cmask clear commands define or remove the mask in use.

  3. Comma separated blocks

    A mask can name several blocks at once, separated by commas, in WorldEdit-style goal syntax.
