Mobcrafter
by oj1755
Mobcrafter lets players build a structure from ordinary blocks, capture it as a single controllable unit and summon that unit back into the world.
What it does
A structure built from vanilla blocks becomes a unit once a capture tool is used on it with a Bone Block placed as the core pivot. The capture takes in the whole connected structure and stores its data, and the saved unit can then be summoned as a living entity that responds to commands.
Commands group nearby units so that every unit inside the command range responds together, which lets a player direct several creations at once. Pre-made units ship with the mod by default, and new additions load while a world is running. On a multiplayer server, units are kept on the server side and synced to the clients.
Installation requires Forge, and the mod is published for 1.20.1, 1.21.10 and 1.21.11, with 1.4.0 for 1.20.1 as the latest file. Mobcrafter runs on client and server, so the server and every player need it. The code is under All rights reserved, and the mod is not open source.

What the author says
MobCrafter is a Forge mod that lets you turn block-built structures into a single controllable unit entity. Instead of spawning mobs, you create units yourself using blocks — then capture, summon, and command them in the world.
