Non-horizontal NavMeshes with multiple NavMeshSurfaces and NavMeshLinks

NavMeshes don’t have to be horizontal (or a slope close to horizontal). Let’s investigate this with NavMeshes on vertical walls and ceilings! We’ll also link different NavMeshes with NavMeshLinks, so our agents can travel through all NavMeshes in a scene.

Getting ready

This recipe adds to the previous one, so make a copy of that project folder and do your work for this recipe with that copy.

How to do it...

To work with non-horizontal NavMeshes, follow these steps:

1. Add a new 3D cube to the scene, named Cube-vertical, at Position (0, 0, 16) and Scale (12, 12, 12). Check the Static option for this GameObject in the Inspector.
2. Move the position of the Capsule-destination GameObject to (0,10,15). You should see the destination capsule floating above our new cube.
3. Select the Terrain in the Hierarchy, and click the Bake button for its Nav Mesh Surface component...
