What is it?

NavMeshPlus is a fork of Unity's NavMeshComponents that adds 2D support. It builds a navigation surface from the geometry in a scene, so characters can compute paths around obstacles in 2D and top-down games. The surface is built on Unity's NavMeshSurface and gathers walkable and blocking sources from tilemaps, sprites and 2D colliders.

The package includes NavMeshSurface, NavMeshLink, NavMeshModifier and NavMeshModifierVolume components, plus 2D source collectors and a cache for sources. Modifiers let you override the area type of individual objects, such as marking a region as non-walkable or assigning a different cost.

It can be installed by copying the folder into Assets, cloning it into the Packages directory, or adding a git URL through the Unity Package Manager.

Key features

  • 01Generates navigation surfaces from tilemaps, sprites and 2D colliders.
  • 02Provides NavMeshLink for connecting separate walkable areas.
  • 03Offers NavMeshModifier and NavMeshModifierVolume to override area types.
  • 04Includes a source cache to speed up repeated bakes.
  • 05Can be installed as a Unity package via git URL or by copying scripts.

Use cases

  • Adding enemy pathfinding to a top-down 2D game built on tilemaps.
  • Letting NPCs walk around 2D collider obstacles in a side-scrolling or top-down scene.
  • Connecting separate platforms or areas with navigation links.
