1.首先在pack manager導入 AI Navigation包

2.參照官方文檔的連接制作跳躍點
https://docs.unity3d.com/Packages/com.unity.ai.navigation@1.1/manual/CreateOffMeshLink.html
注意： 上面的連接跳躍點使用的是Off Mesh Link（Nav Mesh Link）本質上差不太多，自己研究研究就好歉胶，懶得贅述了~
當我們按照文檔操作以后會發(fā)現俺亮，跳躍點其實是走過去的炊汹，不是跳過去的沼本！效果如下

如果要解決這個問題，其實需要額外的代碼來處理跪削，這里官方案例是有的爷速，所以我們導入官方案例。

這里可以看到我的導入按鈕是Reimport啃洋，是因為我已經導入了传货！
導入后，里面有很多案例可以研究宏娄，具體就自己研究了问裕，要解決我們上面的問題，我們需要使用到官方案例的一個腳本孵坚，腳本名字叫“AgentLinkMover”粮宛，所以直接搜索腳本名字，然后掛載到你的Nav Mesh Agent組件的游戲物體上即可卖宠。
如圖：

然后我們運行就會發(fā)現巍杈，可以起跳啦！

大工告成扛伍！
