Unity与VRTK的自定义按键事件_unity steamvr 手柄任意按键按下事件

不想用VRTK插件封装好的手柄按键事件的话，就必须在手柄控制器上挂上SteamVR_TrackedObject脚本，挂上改脚本后运行项目，会自动在手柄控制器生成SteamVR_Controller脚本。

 脚本挂好了后，可以开始写一个自己自定义控制手柄的脚本VR_Controller.cs

using System;
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using Valve.VR;
 
public class VRController : MonoBehaviour
{
    private SteamVR_TrackedObject leftTrackedObj;
    private SteamVR_TrackedObject rightTrackedObj;
 
    void Awake()
    {
        
    }
 
    // Start is called before the first frame update
    void Start()
    {
        OnScenesStart();
    }
 
    // Update is called once per frame
    void Update()
    {
 
    }
 
    void FixedUpdate()
    {
        LeftHandEvenes();
        RightHandEvents();
    }
 
    /// <summary>
    /// Scene initialization
    /// </summary>
    private void OnScenesStart()
    {
        transform.GetComponent<MeshRenderer>().enabled = false;
        transform.GetComponent<SteamVR_PlayArea>().enabled = false;
 
        leftTrackedObj = transform.GetChild(0).GetComponent<SteamVR_TrackedObject>();
        rightTrackedObj = transform.GetChild(1).GetComponent<SteamVR_TrackedObject>();
    }
 
    #region HandEvents
    /// <summary>
    /// Left hand events
    /// </summary>
    private void LeftHandEvenes()
    {
        if (transform.GetChild(0).gameObject.activeSelf)
        {
            var device = SteamVR_Controller.Input((int)leftTrackedObj.index);
            if (device.GetPressDown(SteamVR_Controller.ButtonMask.Trigger))
            {
                print("左手柄按下Trigger键");
            }
            if (device.GetPressDown(SteamVR_Controller.ButtonMask.Grip))
            {
                print("左手柄按下Grip键");
            }
            if (device.GetPressDown(SteamVR_Controller.ButtonMask.ApplicationMenu))
            {
                print("左手柄按下ApplicationMenu键");
            }
            if (device.GetPressDown(SteamVR_Controller.ButtonMask.Touchpad))
            {
                print("左手柄按下Touchpad键");
            }
            if (device.GetTouchDown(SteamVR_Controller.ButtonMask.Touchpad))
            {
                print("左手柄触摸Touchpad键");
            }
            if (device.GetTouchDown(Valve.VR.EVRButtonId.k_EButton_A))
            {
                print("左手柄触摸什么键");
            }
        }
    }
}

以上脚本基本包含了手柄所有事件触发事件，如有需要还可以加一些组合键。
