NavMeshAgent.CompleteOffMeshLink

説明

現在の OffMeshLink 上の移動を完了します。

エージェントは現在の OffMeshLink のもう一方の端の最も近い有効な NavMesh の位置に移動します。

エージェントが OffMeshLink 上でなければ CompleteOffMeshLink は影響しません (参照: 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.
