VRTK3.3.0-002获取手柄事件

1、首先创建VRScripts空物体，用来存放脚本，在其下创建Right空物体并添加VRTK_ControllerEvents脚本

2、Right作为右手手柄，拖拽到[VRTK_SDKManager]的RightController上

3丶在Right上新建脚本RightController，通过得到VRTK_ControllerEvents组件注册方法，就可以监听到按下手柄哪些键了

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using VRTK;//   引用VRTK命名空间

    public class RightController: MonoBehaviour
    {
    private VRTK_ControllerEvents controllerEvents;
    private void Awake()
    {
        controllerEvents = GetComponent<VRTK_ControllerEvents>();
        //  输入+=后按Tab键后自动补全方法
        controllerEvents.TouchpadPressed += ControllerEvents_TouchpadPressed;
        controllerEvents.TouchpadReleased += ControllerEvents_TouchpadReleased;
        controllerEvents.GripPressed += ControllerEvents_GripPressed;
    }

    private void ControllerEvents_GripPressed(object sender, ControllerInteractionEventArgs e)
    {
        Debug.Log("抓取键按下");
    }

    private void ControllerEvents_TouchpadReleased(object sender, ControllerInteractionEventArgs e)
    {
        Debug.Log("圆盘键按释放");
    }

    private void ControllerEvents_TouchpadPressed(object sender, ControllerInteractionEventArgs e)
    {
        Debug.Log("圆盘键按下");
    }
}

还有许多方法这里不逐条列出，大家自行查看VRTK_ControllerEvents脚本

4丶注意：只要涉及到操作手柄，就必须要添加VRTK_ControllerEvents脚本
