Navigation and Pathfinding

【Navigation and Pathfinding】

　　对于开放式场景，轨迹线不适用，NaviMesh此时就派上用场了。Unity的导航系统在已有的Mesh基础上生成一个新的FloorMesh，也叫NaviMesh。通过(menu: Window > Navigation)可以打开Navigation编辑器。

　　

　　

　　Navigation Static：是否根据此网格生成Navimesh。

　　OffMeshLink Generator：是否生成从此网格出发的Link。

　　Navigation Layer：层。

　　Radius： The Radius determines how close a navigating character can get to a wall and consequently the width of the narrowest gap between two walls that can it can squeeze through. 

　　Height：efers to the height of the “ceiling” above the navmesh surface - an area may not be reachable simply because there is not enough headroom for the character

　　Max Slope：parameter sets the threshold of steepness where a ramp becomes a wall

　　Step Height： the maximum height of bump or step in the floor surface that is ignored by the character (any step greater than this height results in a disconnected walkable area rather than a continuation of the same area).
