bool True if the nearest edge is found.
特定の位置からもっとも近いナビメッシュオブジェクトの辺の情報を取得します
返される NavMeshHit オブジェクトは NavMesh の最寄りの端に最も近いポイントの位置と詳細が含まれています。 これを使用してエージェントの周りにどのくらいの余分なスペースがあるか参照するために使用できます。

filter | A filter specifying which NavMesh areas can be passed when finding the nearest edge. |
bool True if the nearest edge is found.
Locate the closest NavMesh edge from a point on the NavMesh, subject to the constraints of the filter argument.
The returned NavMeshHit object contains the position and details of the nearest point on the nearest edge of the NavMesh. This can be used to query how much extra space there is around the agent.
