WarMachineLib

Soldier and vehicle creatures are the core of the library. It supplies firing systems, base templates, AI, and a simple command system that lets players operate vehicles. Entity rendering uses OBJ models loaded through the OBJ loader that comes from MWFS, and the author reports that tens of thousands of models render smoothly. Lighting, light and shadow compatibility is included.

Combat units are split into two categories. Squad-type units carry more complete AI and larger NBT data, which suits small-scale team operations and lets players configure soldiers and vehicles more precisely. RTS-type units have only basic mobility and attack abilities with fewer NBT entries, which keeps them lighter and better optimized for large-scale battles. The vehicle system favors simplicity and ease of use over hardcore realism, and its key operation follows the layout of BF2.

The library is published for Forge only. Files cover 1.16.5 and 1.20.1, and the 1.16.5 port still has some unresolved issues. Effects weapons, bullets, explosions and vehicle entities can be installed alongside the special effects module, which is linked to it. The client and server both need the mod, and the module is licensed under the same Creative Commons Attribution Non Commercial Share Alike 4.0 terms, so it is not open source.
