JPS4+ Lite 2D Grid Pathfinding

JPS4+ 2D Pathfinding is a tile-based Burst pathing solution tailored for 2D grids that generates paths dynamics (no caching needed!). This stands out from other 2D pathing solutions because it implements Jump Point Search Pathfinding in 4-connected Grids (Johannes Baum 2025)

For dense maps, JPS4 can give >10x improvement v.s. A* by reducing the search space to remove unnecessary node expansions (theoretical upper limit of >50x improvement on longer paths). This asset is made for 2D Grid-Based Movement (think rooks & queens in chess). Included dynamic obstacle support and closest target search.

Full Version (Pro): https://assetstore.unity.com/packages/slug/jps4-2d-grid-pathfinding-355438

This (free) version implements the same core algorithms, but runs synchronously on the main thread. This package is meant to be a trial for the full version which is highly optimized and uses performant Burst/Jobs 2D pathfinding package for dynamic pathfinding on a grid. Includes flexible extendable code and API for multiple grids, agents, and movement components. Supports A* (4 and 8-connected) and both vertical and horizontal-first JPS4 algorithms.
