快速开发实用工具VRTK-006

006_Controller_UsingADoor

打开门

在左右手柄上挂载，VRTK_ControllerEvents、VRTK_Interact Touch、VRTK_Interact Grab和VRTK_Interact Use。如下图所示：

然后在门上挂载脚本Openable_Door，继承自VRTK_Interactable Object。在抓取的四个脚本添加之后，又添加了VRTK_Interact Use（按下控制器上默认的扳机键来使用一个对象，释放该按钮停止使用该对象）。
在与可交互对象产生交互时，对象上往往需要一个脚本组件，该组件既可以使VRTK_InteractableObject,也可以是继承于该类的子类。Openable_Door就是VRTK_InteractableObject的子类。
