2D NavMesh

In repo you will find implementation of NavMeshSurface2d for tilemap top down games.

To use it in your project:

  1. Copy repo into your Asset folder
  2. Create Empty Object in scene root and rotated respectively to Tilemap (x-90;y0;z0)
  3. Add NavMeshSurface2d component to Empty Object
  4. Add Tilemap with NavMeshModifier component, override the area.
  5. In NavMeshSurface2d hit Bake.

How does it works:

  1. It uses as base implementation.
  2. Implements world bound calculation.
  3. Implements source collector of tiles, sprites and 2d colliders
  4. Creates walkable mesh box from world bounds.
  5. Convert tiles, sprites and 2d colliders to sources as NavMeshBuilder would do.
