C# Unity XR VR输入和GetDeviceWithCharacteristics语法可能存在问题？

我不得不注释掉我的一堆代码，但归结起来有两个错误。问题似乎出在使用“GetDevicesWithCharacteristics”的行上，因为这也是错误所在，但我检查了文档，结果似乎不错。我还检查了上面的行，我不确定“LeftHandedController；”我在事后加上了这句话，是为了跟在文档后面，这其实不是问题所在

我没有经验，所以如果这是一个简单的错误，请原谅我

using UnityEngine.Events;
using UnityEngine.XR;

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class controlerInputScript : MonoBehaviour
{
    GameObject gameObjectToMove;
    public int scale = 3;


    var leftHandedControllers = new List<UnityEngine.XR.InputDevice>();
    InputDeviceCharacteristics leftcontrollerdesiredCharacteristics = UnityEngine.XR.InputDeviceCharacteristics.HeldInHand | UnityEngine.XR.InputDeviceCharacteristics.Left | UnityEngine.XR.InputDeviceCharacteristics.Controller, leftHandedControllers;
    InputDevices.GetDevicesWithCharacteristics(XR.InputDeviceCharacteristics leftcontrollerdesiredCharacteristics, List<InputDevice> leftHandedControllers);


    // var rightHandedControllers = new List<UnityEngine.XR.InputDevice>();
    // var rightcontrollerdesiredCharacteristics = UnityEngine.XR.InputDeviceCharacteristics.HeldInHand | UnityEngine.XR.InputDeviceCharacteristics.Right | UnityEngine.XR.InputDeviceCharacteristics.Controller;
    // UnityEngine.XR.InputDevices.GetDevicesWithCharacteristics(rightcontrollerdesiredCharacteristics, rightHandedControllers);


    // if (leftHandedControllers > 1) || (rightHandedControllers >1){
    //     Debug.Log("DEBUG: ERROR: More than one Left or Right handed controller detected!")
    // }

    //assign Controlllers
    InputDevice leftController = leftHandedControllers[0];
    //InputDevice rightController = rightHandedControllers[0];

    // Start is called before the first frame update
    void Start()
    {
        
    }

    // // Update is called once per frame
    void Update()
    {
        Vector3 p = this.transform.position;
        float leftTriggerState;
        if (leftController.TryGetFeatureValue(CommonUsages.trigger, out leftTriggerState)){
            p.y = scale * leftTriggerState;
            gameObjectToMove.transform.position = p;
        }
     
    //     float rightGripState;
    //     if (rightController.TryGetFeatureValue(CommonUsages.grip, out rightGripState)){
    //         p.x = scale* rightGripState;
    //         gameObjectToMove.transform.position = p;
    //     }
    }
}

提前谢谢你的帮助

我说的是那些台词

var leftHandedControllers = new List<UnityEngine.XR.InputDevice>();
InputDeviceCharacteristics leftcontrollerdesiredCharacteristics = UnityEngine.XR.InputDeviceCharacteristics.HeldInHand | UnityEngine.XR.InputDeviceCharacteristics.Left | UnityEngine.XR.InputDeviceCharacteristics.Controller, leftHandedControllers;
InputDevices.GetDevicesWithCharacteristics(XR.InputDeviceCharacteristics leftcontrollerdesiredCharacteristics, List<InputDevice> leftHandedControllers);

在第二行，你确定吗

，左撇子控制器

因为此语法不正确，也没有任何语义

在第三行中，您试图在参数中执行什么操作！您正在重新定义函数参数中以前的变量

我相信您的代码应该是：

var leftHandedControllers = new List<UnityEngine.XR.InputDevice>();
InputDeviceCharacteristics leftcontrollerdesiredCharacteristics = UnityEngine.XR.InputDeviceCharacteristics.HeldInHand | UnityEngine.XR.InputDeviceCharacteristics.Left | UnityEngine.XR.InputDeviceCharacteristics.Controller;
InputDevices.GetDevicesWithCharacteristics(leftcontrollerdesiredCharacteristics, leftHandedControllers);

我做了更多的检查，确定错误来自GetDeviceWithCharacteristics行。我还可以使用另一种方法来复制错误，即获取控制器GetDevicesWithRole。当我取消注释它们时，两个错误都发生了两次。这似乎是一个语法错误，但据我所知，我似乎在遵循文档。好的，如果您可以共享此文档，检查您是否遗漏了一些内容可能会有所帮助

var leftHandedControllers = new List<UnityEngine.XR.InputDevice>();
InputDeviceCharacteristics leftcontrollerdesiredCharacteristics = UnityEngine.XR.InputDeviceCharacteristics.HeldInHand | UnityEngine.XR.InputDeviceCharacteristics.Left | UnityEngine.XR.InputDeviceCharacteristics.Controller;
InputDevices.GetDevicesWithCharacteristics(leftcontrollerdesiredCharacteristics, leftHandedControllers);
