New:Sim-U-Kraft
New:Sim-U-Kraft turns an empty plot of land into a city, with a City Core, claimable chunks and residents who build, farm, trade and haul goods.
What it does
A city starts with a City Core. From there a player claims chunks, manages the city's funds and grows its population. Buildings are picked from the Build Box, previewed in the world and confirmed, after which hired builders gather materials and construct them. Residents take on roles in construction, planning, agriculture, retail, manufacturing and transport, letting a small settlement expand into housing, fields, stores, plants, storage buildings and item paths.
The simulation runs on the server, which handles city data and resident work, while the client draws the HUDs, screens, building previews and status updates. The mod is built for both singleplayer worlds and dedicated servers. LDLib is required, and the matching LDLib2 build is needed for each supported Minecraft version. Files are published for NeoForge and Forge across 1.20.1 and 1.21.1, with 2.2.0 for 1.21.1 as the latest NeoForge file and 1.1.0-fix-v1-1.20.1 as the latest Forge file for 1.20.1.
Localization is available in English and Simplified Chinese, and client and server options can be configured. An optional setting highlights city areas on a world map. The code is released under the GNU General Public License v3.0 only, and the source code and issue tracker are public.
