| iterations | 在此调用期间搜索算法遍历的最大节点数。 |
| iterationsPerformed | 输出在此调用期间已遍历的实际节点数。 |
PathQueryStatus
如果需要通过再次调用 UpdateFindPath 以进一步继续搜索，则返回 /InProgress/。
如果搜索已完成并且不管有没有找到路径，都返回 /Success/。
如果由于自搜索启动以来 NavMesh 发生了重大变化，导致无法完成对所需位置的搜索，则返回 /Failure/。
此外，当 NavMeshQuery 初始化的 pathNodePoolSize 参数不足以容纳搜索空间时，返回的值可能包含 OutOfNodes 标志。
继续进行正在进行的路径搜索。
此操作需要先前使用 NavMeshQuery.BeginFindPath 进行初始化，它将一直运行，直到找到整个路径或执行了指定的迭代次数为止。
只要先前调用返回了 InProgress 的状态，就可以跨不同的帧重复调用此方法，直到操作成功为止。随后使用 NavMeshQuery.EndFindPath 准备要检索的路径数据以及所包含的节点数量。
