rlballsym

Rust implementation of ball path prediction for Rocket League; Inspired by Samuel (Chip) P. Mish's C++ utils called RLUtilities.

This crate also contains fixes to discovered errors stemming from the original repo.

Running

Make sure you have Rust/Cargo installed, then just run cargo test --release in the terminal.

Example implementations

Check out the examples folder! If you want to run them and don't know how:

bat cargo run --example example_name

For example, to run the example basic.rs:

bat cargo run --example basic

Performance numbers

Numbers are with default features from a system running Ubuntu 22.10 with a Ryzen 9 5900X with 3600MHz CL18 RAM.

Numbers will vary depending on your system.

Features

• uncompressed: Default feature. Enables the loading of uncompressed binary field data, which is faster but increases the size of the final binary.
• compression: Nightly only - Minimize the size of the produced binaries by compressing the binary field data at compile time. Will slightly slow down load_x() functions.
• stable-compression: Does the same as compression using the same crate, but available for use in stable Rust.
• fast-math: Enables the fast-math feature in the glam crate.
