2D NavMesh

In repo you will find implementation of NavMeshSurface and 2d Extensions for tilemap, sprites and collider2d top down games.

To use it in your project:

1. Copy repo into your Asset folder (or install as a package).
2. Create Empty Object in scene root.
3. Add "Navigation Surface" component to Empty Object and add NavMeshCollecSources2d component after.
4. Click Rotate Surface to XY (to face surface toward standard 2d camera x-90;y0;z0)
5. Add "Navigation Modifier" component to scene objects obstacles, override the area.
6. In "Navigation Surface" hit Bake.

How does it works:

1. It uses NavMeshSurface 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.
