M.A Editor (Multi Area Editor)

This datapack for Minecraft 1.21.4 (i didn't tested on older but on newer version special tool (armor stand) will have glitch with item name)

this datapack adds 3 new functions


1. You need to get special tool (armor stand) using command /function maeditor:gettool
2. Place armor stand where on any block (you can place multiple to create big area selection)
3. Create command to use for example (/setblock ~ ~-1 ~ sand)
4. Run this command (/function maeditor:execute {cmd:"COMMAND"} (instead of word COMMAND put your command WITHOUT SLASH) example (/function maeditor:execute {cmd:"setblock ~ ~-1 ~ sand"} )

OPTIONAL 5. Use command /function maeditor:clear to remove all placed armor stands from datapack
