unity navmesh相关_运行时生成可通过的桥

运行时候动态的桥面。

方式1：使用navMeshSurface.BuildNavMesh()动态创建

方式2：官方案例2中 

LocalNavMeshBuilder.cs

NavMeshBuilder.UpdateNavMeshDataAsync
或

NavMeshBuilder.UpdateNavMeshData

 1         void UpdateNavMesh(bool asyncUpdate = false)
 2         {
 3             NavMeshSourceTag.Collect(ref m_Sources);
 4             var defaultBuildSettings = NavMesh.GetSettingsByID(0);
 5             var bounds = QuantizedBounds();
 6     
 7             if (asyncUpdate)
 8                 m_Operation = NavMeshBuilder.UpdateNavMeshDataAsync(m_NavMesh, defaultBuildSettings, m_Sources, bounds);
 9             else
10                 NavMeshBuilder.UpdateNavMeshData(m_NavMesh, defaultBuildSettings, m_Sources, bounds);
11         }

估计每个动态的“floor”对应一个surcface性能会好一些，冗余数据少。
