polygon | 要检查的导航网格节点的标识符。 |
如果指定 PolygonId 引用的节点在导航网格中处于活动状态,则返回 true。
导航网格节点将在以下情况变为无效:其所属导航网格表面或链接被删除,或者由于其所在区域的导航网格修改,它们已被替换。可以通过调用 NavMesh.RemoveNavMeshData 和 NavMesh.RemoveLink 来删除导航网格表面和链接。可以通过调用 NavMeshBuilder.UpdateNavMeshData 来修改导航网格,也可以使用 NavMeshObstacle 来雕刻导航网格。
location | 导航网格上要检查的位置。与直接检查 location.polygon 相同。 |
如果 NavMeshLocation 中所含 PolygonId 引用的节点在导航网格中处于活动状态,则返回 /true/。
