1.首先在pack manager导入 AI Navigation包
QQ截图20231014124003.png
2.参照官方文档的连接制作跳跃点
https://docs.unity3d.com/Packages/com.unity.ai.navigation@1.1/manual/CreateOffMeshLink.html
注意： 上面的连接跳跃点使用的是Off Mesh Link（Nav Mesh Link）本质上差不太多，自己研究研究就好，懒得赘述了~
当我们按照文档操作以后会发现，跳跃点其实是走过去的，不是跳过去的！效果如下

如果要解决这个问题，其实需要额外的代码来处理，这里官方案例是有的，所以我们导入官方案例。

这里可以看到我的导入按钮是Reimport，是因为我已经导入了！
导入后，里面有很多案例可以研究，具体就自己研究了，要解决我们上面的问题，我们需要使用到官方案例的一个脚本，脚本名字叫“AgentLinkMover”，所以直接搜索脚本名字，然后挂载到你的Nav Mesh Agent组件的游戏物体上即可。
如图：

然后我们运行就会发现，可以起跳啦！

大工告成！
