返回null的VRTK_ControllerEvents

Question

我正试着用SteamVR和VRTK制作一把枪，但我不知道如何正确地获得控制器输入。当我使用SteamVR跟踪控制器脚本时，我得到一个IsMatrixValid错误，它弄乱了我的头盔显示器。我目前正在尝试使用VRTK控制器事件方法，但即使我正确地跟踪了视频，它仍然作为null返回。

有问题的脚本：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using EZEffects;
using VRTK;


public class GunBehavior : MonoBehaviour {

public VRTK_ControllerEvents controllerEvents;

private SteamVR_TrackedObject trackedObj;


public EffectTracer TracerEffect;
public Transform muzzleTransform;

// Use this for initialization
void Start () {
    Debug.Log(controllerEvents);
    if (controllerEvents)
    {
        Debug.Log("Hue22");
    }
    else
    {
        Debug.Log("work");
    }
}

// Update is called once per frame
void Update () {

    if (controllerEvents.triggerPressed)
    {
        ShootWeapon();
    }
}

void TriggerPressed(object sender, VRTK.ControllerInteractionEventArgs e)
{
    ShootWeapon();
}

void ShootWeapon()
{
    RaycastHit hit = new RaycastHit();
    Ray ray = new Ray(muzzleTransform.position, muzzleTransform.forward);

    TracerEffect.ShowTracerEffect(muzzleTransform.position, muzzleTransform.forward, 250f);

    if (Physics.Raycast(ray, out hit, 5000f))
    {
        Debug.Log("Hueheuhue");
    }
}
}

从你的脚本中删除这3行代码，它就可以工作了

void TriggerPressed(object sender, VRTK.ControllerInteractionEventArgs e)
{
    ShootWeapon();
}
