Spine runtime for Rust (and wasm!) transpiled from the official C Runtime. Supports Spine 3.8 and 4.1.
[dependencies]
rusty_spine = "0.3.1"
A Rust API is provided on top of the C API, because working with C APIs directly in Rust is tedious and error prone. It's made to be as thin a wrapper as possible.
The Rust API is unstable and changes often.
If you wish to use the C API directly (either because the Rust API lacks a feature or for performance reasons), it is available under the rusty_spine::c import. See the C example.
Because this project uses the official Spine Runtime, you must follow the Spine Runtimes License Agreement. If using the libc crate (via the use_libc feature), then see the libc crate for licensing. If using the built-in (wasm compatible) libc implementation, you must follow the BSD 3-clause license of The Regents of the University of California. See the LICENSE file for complete licenses. The Rust code is licensed under dual MIT / Apache-2.0 but with no attribution necessary. All contributions must agree to this licensing.
Default: no
A small subset of libc is provided in this repo to avoid a dependency on libc and to allow the code to run in the wasm32-unknown-unknown target. However, it's possible to rely on the OS implementation of libc instead by using the use_libc feature.
Default: yes
Provides helper functions for generating mesh data, as well as the SkeletonController helper struct.
Default: no
Provides an egui debugger window for viewing skeleton and animation state. See it in action by running the bevy example with this feature enabled:
cargo run --release --example bevy --features egui_debugger
Default: yes
Provides additional math functions using mint.
Default: no
Builds a Spine 3.8-compatible runtime instead of a 4.1-compatible one. Enable this feature if you are loading files saved with Spine 3.8.x instead of 4.1.x.
