In Unity, how to have a navmesh that dynamically update the location of areas
问题
我正在尝试制作一个2D顶视游戏，玩家需要移动障碍物来阻止敌人AI前进，但我需要这些障碍物只阻挡特定类型的敌人。
我尝试过使用Unity的障碍物，但它们会影响到每一个导航网格，所以每个角色都会避开它们（而且我需要将它们设置为"carve"，因为如果敌人被困住，我需要他们选择另一条路径）
我考虑过创建一个能改变其下方区域而不是切割网格的障碍物，但我没有找到动态实现这一点的方法，而不需要重新烘焙整个导航网格。
是否有办法实现这一点，或者是否有插件可以提供这些功能？谢谢。

I am trying to make a 2d top-down game where the player moves obstacles in order to block enemy AI from advancing, but I need the obstacles to only block certain types of enemies.
I've tried using Unity obstacles but they carve through every navmesh so every Agent will avoid them (And I need to set them to carve because I need enemies to take another path if they are stuck)
I've thought about having an obstacle that change the area beneath it instead of carving through the mesh, but I haven't seen any ways to dynamically do that without baking the whole navmesh again.
Is there any way to do that, or a plugin that could give me those features ? Thank you

你绝对应该查看A*寻路项目。在使用了这个之后，我真的无法再回到使用Unity内置的导航网格系统。

他们内置了针对你这种类型情况的解决方案，即有不同的AI层/组。
如果你想尝试的话，有一个免费版本可用

You should definitely check out the A* Pathfinding Project. After using this I really can't go back to using Unity's built-in navmesh system.

They have built in solutions for exactly your type of situation, ie. there are different layers/groups of AI.
There is a free version available if you would like to try it out
