Navmesh Obstacle Component

The navmesh obstacle component is used to inform the navmesh system, that a certain area has changed (blocked or unblocked) and needs to be regenerated.

This is mainly intended for large objects that either appear or disappear (for example when a player places a building) or that move only infrequently, such as a city gate opening after some quest got completed. It will not work for freely moving obstacles that would require avoidance by NPCs.

The obstacle must have a physical collider to represent its shape. The obstacle component automatically informs the navmesh that a navmesh sector is outdated when the component becomes active and inactive. If necessary, it can also be triggered externally to invalidate the sector again, for example when it moved.
