Welcome to PathEngine, home of the most advanced pathfinding library commercially available.

Go beyond nav-meshes with robust integrated dynamic obstacle management.

PathEngine's sophisticated points-of-visibility core means:

  • A powerful and well-defined motion space description (essentially: augmented navigation meshes for ground management + static and dynamic obstacle detail + automatic expansion by pathfinding agent shape).
  • Paired pathfinding and collision, for efficient and effective reactive behaviours and fundamentally robust movement planning.
  • Fast pathfinding over long distances, with no aliasing.

Commercial clients are invited to request an evaluation.
Full support will be provided during your evaluation.

Students and hobbyists are invited to try out the 'testbed-only' version of the SDK, which can be found on the downloads page.
Source code for the demo is also provided. This is a great way, then, to get started learning about implementing intelligent agent movement.

Extensive documentation is available online, here.
