box2d-rs

A native port of Box2D to Rust.

Minimum Rust version: 1.47.0

Ported Box2D version: 2.4.1

When porting, I pursued the following goals - Keep file system structure as is for simpler further updates - Keep all identifiers names(except case convertion) and code order(except some specific cases) - Store all new not original code in separate files

TODO

• [ ] convert comments from doxygen to rustdoc
• [ ] replace imgui unsafe blocks by safe
• [ ] fix some comments
• [ ] fix deprecation warning in glium modifiers

Known differences

• dump() function replaced by serde library (optional dependency)
• comments converted from doxygen to rustdoc
• two additional buttons in the testbed's UI for serialize/deserialize (available only with serde_support feature). Serialized data available in serialize_test directory
• query/raycast callback class replaced by closure

Usage

Add this to your Cargo.toml:

toml [dependencies] box2d-rs = "0.0.2"

If you want serialize/deserialize world with serde:

toml [dependencies] box2d-rs = { version = "0.0.2", features = ["serde_support"] }

Compiling and running the testbed from source

Build and run testbed in debug mode:

```bash

At the reposity root

cargo build --examples --tests cargo run --example testbed ```

In debug mode with serde_support: bash cargo build --examples --tests --features serde_support cargo run --example testbed --features serde_support

Release version with serde_support: bash cargo build --examples --tests --release --features serde_support cargo run --example testbed --release --features serde_support

Run tests bash cargo test --features serde_support

Crate features

Optionally, the following dependencies can be enabled:

• serde_support enables serialize/deserialize of world via the serde crate
