It is also intended for any research, study or teaching activity, around physics and AI, thanks to its GPL V2+ license, and the clear and modular architecture of its C/C++ code base.

    Sims 3 Package Interface

    Sims 3 (and other) game package library

    "Sims 3 Package Interface" provides a core library of portable code that "understands" Sims3 game packages. Note that (with some minor tweaks) the core library code also understands other game package formats (e.g. SimCity Online, Sims4). Along with the core library are a number of "wrappers" that provide the main part of the project. These handle deserialization and serialization of data within the package (or any other source). Further tools (not supplied here) can use the core library and wrappers to manipulate the data content of package files. Note that development on this library and wrappers provided here has now finished.
