SysTools
SysTools adds a small scripting language, MineScript, and a few new commands that run it, for NeoForge on 1.21.1.
What it does
Players and server owners can write logic chains in MineScript, a language built on top of the basic Minecraft commands. The mod also adds a handful of commands such as shoot, itemcommand, links and multicmd, which run several commands in one step. A multicmd call can, for example, chain a say command with a second message. The file targets 1.21.1 only, and it runs on the client and the server together, so both sides need it. The license is All rights reserved, which means the code is not open source.
