Physis
Physis is a Rust library for reading and writing FFXIV data.
use ;
Physis can be used to apply patches for launchers or build modding tools! We can also power server emulators which deal with a lot of Excel and zone data.
Supported Game Versions
We aim to support all game versions and expansions, including the benchmarks. We also try to support all platforms, including defunct ones like the Playstation 3.
Physis does not support FINAL FANTASY XIV 1.x, except for applying their ZiPatch files.
Supported Target Platforms
Physis compiles and runs on all major platforms including Windows, macOS, Linux and WebAssembly.
Usage
To use Physis in your project, add it as a dependency in your Cargo.toml:
[]
= "0.5"
Documentation is available online at docs.xiv.zone. It's automatically updated as new commits are pushed to the main branch.
C, C++ and others
C and C++ projects (or any compatible language through FFI) can use libphysis.
Contributing & Support
Feel free to submit PRs for fixing bugs or adding functionality. Filing issues is appreciated, but I do this in my free time so please don't expect professional support.
