Navigation requires the use of a simplified geometrical plane, often called a navmesh. The navmesh enables characters to plot a path around the various complex items in a scene. In this video we will look at how to create a navmesh (often called "baking") using Unity's Navigation view.

The navmesh agent is responsible for moving our characters around a scene and finding paths in a navmesh. In this video you will learn all about the navmesh component and how to use it to bring your characters to life.

Offmesh links provide simple paths between pieces of navmesh. In this video we will look at creating offmesh links using either Unity's auto-generating features, or manually using the offmesh link component.

Navmesh obstacles provide a dynamic way to block agent pathfinding on a navmesh. These items are not baked into the navmesh, and thus can move around freely while getting in the way. In this video we will learn about the navmesh obstacle component and how to apply it to objects in a scene.
