## What it is
NavMeshPlus is a Unity library that extends Unity's NavMeshComponents with 2D pathfinding support, generating navigation meshes from tilemaps, sprites, and 2D colliders. It provides NavMeshSurface and related components tailored for top-down 2D games.

## Use cases
- add navmesh pathfinding to a 2d unity game
- bake navigation mesh from tilemaps and sprites
- make enemies navigate around 2d colliders
- top-down 2d character movement with pathfinding
- unity 2d navmesh alternative to a* grid pathfinding
- create walkable areas for 2d agents in unity

## When to choose
- building a Unity 2D top-down game needing navmesh-based pathfinding
- you want automatic navmesh baking from tilemaps, sprites, or Collider2D
- you prefer Unity's NavMesh API over custom grid A* implementations

## When to avoid
- working in 3D Unity projects (use built-in NavMeshComponents)
- using a non-Unity engine like Godot or Unreal
- needing grid-based or flow-field pathfinding instead of navmesh

## Facets
- artifact type: library
