I recently tried to interact with command blocks in Minecraft 1.16 Fabric and the latest WorldEdit version. I wanted to implement it somehow that I press a button and then WorldEdit marks a previously "set" area and replaces it with earth, for example. But it didn't work. : /
Does anyone know a mod, an addon, server plugin or something else that can be used to do this? Is it practically very easy and quick to select the same region again and again at the push of a button, even after you had selected something different in between?
Why don't you use the / clone and / fill commands? You could write them in a command block, with which it would work.
For the 1.8 there was a plugin that allowed WorldEdit to be executed using a command block. https://dev.bukkit.org/.../cbwrapper
But there's probably no such plugin for the 1.16. Find none either.
