Rust bindings for Recast Navigation.

Divert

Rust bindings for Recast Navigation.

Purpose

Provide safe bindings to Recast Navigation to allow for 3d navigation in a rust application.

Overview

src/extern.cpp

C function definitions wrapping Detour C++ Functions.

src/binding.rs

Rust bindings to the C functions exposed in src/extern.cpp.

src/lib.rs

Safe Rust abstractions of Detour components e.g ensuring correct freeing of DtNavMesh and DtNavMeshQuery.

How to Build

git clone --recurse-submodules https://github.com/0xFounders/divert.git
cargo build

Use Case

Refer to examples/pathfinding.rs for a demonstration of loading geometry generated with Trinity Core. In the below, Proof of Concept, section the paths generated are projected to in-game space. In this repository the resources for generating paths is provided, but drawing/projecting points in the game is not in scope of this project. No questions or issues should be opened requesting help or information about video game specific applications.
