NavMeshAgent.CompleteOffMeshLink

Description

Completes the movement on the current OffMeshLink.

The agent will move to the closest valid navmesh position on the other end of the current OffMeshLink.

CompleteOffMeshLink has no effect unless the agent is on an OffMeshLink (Additional resources: isOnOffMeshLink).

When autoTraverseOffMeshLink is disabled an agent will pause at an off-mesh link until this function is called. It is useful for implementing custom movement across OffMeshLinks.
