Unity HTC VIVE Teleportation
本文关键字：Teleportation VIVE HTC Unity | 更新日期: 2023-09-27 17:57:59
我正在为HTC VIVE开发，并试图创建一个传送脚本，当用户抓取某个对象时，该脚本将允许用户传送到某个位置（由我预定义）。我目前有一个传送码，它的工作原理就像普通的传送机，用户指向一个位置，房间就会移动到那个位置。我修改了这个，这样无论用户指向哪里，他们都会传送到特定的位置。这是第一步，但我真的很想在用户拿起某个物体时触发这种传送，有人知道在哪里或如何做到这一点吗？
这是修改后的传送机的代码：

您是如何挑选对象的。你是使用某种光线投射还是只是在碰撞时拾取？然而，当物体被拾取时，无论你想做什么触发传送，都应该像从你用来拾取物体的任何脚本中调用传送脚本一样简单。例如：
void OnTriggerEnter(Collider other)
{
if (other.gameObject.CompareTag ("Pick Up"))
{
<<call your teleport script here>>
}
}
Unity有非常好的脚本文档，你可以找到很多解释基本知识的教程，即使你看过其中一个，你也应该能够相对轻松地做任何你想做的事情。
