Tilemap Pathfinder

A lightweight pathfinding solution built around Unity's Tilemap system.

Features

• Works with any Unity Tilemap layout, including:

  • Square grids
  • Isometric grids
  • Hexagonal grids

• Grid type agnostic. The pathfinder relies on Unity's Tilemap API for coordinate conversion, so the same calls work across different tile layouts.

• No practical grid-size limitation beyond int.MaxValue.

• Simple API and minimal setup.

How to Use

Take a look at PathfinderDebug.cs for a basic implementation example.

To calculate a path, enqueue a request to the pathfinder scheduler

• A start position
• A destination position
• The Tilemap used as your obstacle layer

The pathfinder handles the required coordinate conversion internally through Unity's Tilemap API.

ToDo

• Scheduler
• Path Smoothing
