RecursiveAI.OnePath

Pathfinding and navigation for .NET, written from first principles: grids, graphs, navigation meshes and crowds in one package. Results are bit-identical on every platform, so it is safe inside a lockstep or rollback game simulation.

Preview. The API can still change between previews.

  • Grids and graphs: square (4- and 8-connected), hex and 3D voxel grids; A*, JPS, JPS+, Theta*, Lazy Theta*, HPA*, LPA* and D* Lite replanning, flow fields, area costs, agent sizes; weighted and point graphs with bidirectional search and ALT landmarks.
  • Navigation meshes: an exact 2D builder (outlines, tile maps) and a Recast-class 3D builder (triangle soup, glTF, voxel chunks) into one tiled format, with path, string-pulling, raycast, nearest-point and random-point queries, run-time tile rebuild and obstacles, off-mesh links, several agent sizes and streaming.
  • Crowds: path corridors and navmesh-aware ORCA avoidance, fixed-step, with byte-exact snapshot and restore.
  • Determinism: only IEEE-exact + - * / and sqrt, our own transcendental functions (RecursiveAI.OneMath, the only dependency), fixed reduction orders and index-ordered parallel work. Time slicing counts iterations, never clock time.
  • Platforms: net10.0 on Windows, Linux and macOS (x64 and arm64), NativeAOT and trimming (an app that only uses grids trims the navmesh builders away), browser WASM.
using RecursiveAI.OneMath;
using RecursiveAI.OnePath;

var grid = Grid.FromText("""
    ........
    .#####..
    .#...#..
    .#.#.#..
    ...#....
    """);
GridPath path = grid.FindPath(new Cell(0, 0), new Cell(4, 3));

NavMesh level = NavMesh.Build(triangles, NavSettings.Humanoid);
PathResult route = level.FindPath(new Vector3D(3, 0, 3), new Vector3D(36, 0, 36));

Crowd crowd = level.CreateCrowd();
Agent walker = crowd.Add(new Vector3D(3, 0, 3), Agent.Humanoid);
walker.SetDestination(new Vector3D(36, 0, 36));
crowd.Step(0.05);   // fixed time step; the crowd has no clock of its own
