パスを計算するサービス。
| キーポイント | 詳細 |
|---|---|
| PathfindingService | パスを計算するサービス。 |
| Path | 計算されたパスを表すオブジェクト。 |
| Waypoints | キャラクターが従うべきパスに沿ったポイント。 |
| Agent Parameters | キャラクターの移動能力と制限を定義するパラメータ（例：半径、高さ、ジャンプ高さ）。 |
| Blocked Event | パスがブロックされたときに発生するイベント。 |
| StatusChanged Event | パスのステータスが変更されたときに発生するイベント。 |
