NavMeshAgent.CompleteOffMeshLink

切换到手册
public void CompleteOffMeshLink ();

描述

完成在当前 OffMeshLink 上的移动。

代理将移动到当前 OffMeshLink 另一端上最近的有效导航网格位置。

除非代理在 OffMeshLink 上,否则 CompleteOffMeshLink 将不起作用(另请参阅:isOnOffMeshLink)。

autoTraverseOffMeshLink 被禁用时,代理会在网格外链接处暂停,直到此函数被调用为止。 此函数可用于跨越 OffMeshLink 实现自定义移动。
