c# - Unity HTC VIVE 远距传送

Question

我正在为 HTC VIVE 开发并尝试创建一个传送脚本，当用户捕获某个对象时，该脚本允许用户传送到某个位置(由我预先定义)。我目前有一个传送代码，它像普通的传送器一样工作，用户指向一个位置，房间就会移动到那个位置。我对此进行了修改，以便无论用户指向何处，他们都将始终传送到特定位置。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，有没有人知道在哪里加注星标或如何执行此操作？

这是修改后的传送器的代码:

Answer 1

你是如何尝试挑选对象的。您是使用某种射线转换还是只是碰撞？然而，无论您想在拾取对象时触发传送，都应该像从用于拾取对象的任何脚本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，您可以找到很多解释基础知识的教程，即使您阅读了其中的一个，您应该能够相对轻松地完成大部分您想做的事情。
