找不到类型或命名空间名称“RenderModel”Unity3d SteamVR

Question

嗨，我正在 Unity3D 中为 UWP 制作 VR 家庭应用程序，我收到此错误，该应用程序执行以下操作：列出所有用户安装的应用程序并在画布中列出图标，当用户单击它们时，它会打开他们单击的应用程序在

这是代码：

using UnityEngine;
using UnityEngine.UI;
using System.Linq;
using Valve.VR;

public class OpenApp : MonoBehaviour
{
    // reference to the canvas that will display the app icons
    public Canvas appCanvas;

    // reference to the prefab for the app icon buttons
    public Button appIconPrefab;

    // reference to the OpenVR system
    public CVRSystem vrSystem;

    // reference to the OpenVR applications interface
    public IVRApplications vrApps;

    // reference to the app model
    private RenderModel appModel;

    // called when the script is enabled
    public void OnEnable()
    {
        // get the OpenVR system
        vrSystem = OpenVR.System;

        // get the OpenVR applications interface
        vrApps = OpenVR.Applications;

        // get a list of installed apps
        uint appCount = vrApps.GetApplicationCount();
        string[] appList = new string[appCount];
        for (uint i = 0; i < appCount; i++)
        {
            appList[i] = vrApps.GetApplicationKeyByIndex(i, EVRApplicationError.None);
        }

        // sort the app list by app name
        appList = appList.OrderBy(app => app).ToArray();

        // iterate over the app list
        foreach (string appPath in appList)
        {
            // create a new app icon button
            Button appIcon = Instantiate(appIconPrefab);

            // set the parent of the app icon button to the canvas
            appIcon.transform.SetParent(appCanvas.transform);

            // set the position and rotation of the app icon button
            appIcon.transform.localPosition = Vector3.zero;
            appIcon.transform.localRotation = Quaternion.identity;

            // set the app path as the command for the app icon button
                        appIcon.onClick.AddListener(() => LaunchApp(appPath));

            // TODO: set the app icon for the app icon button
            // You can use the RenderModel class to load the app icon, or you can use a different method to retrieve the app icon from the app path.
        }
    }

    // called when the script is disabled
    private void OnDisable()
    {
        // destroy all app icon buttons
        foreach (Transform child in appCanvas.transform)
        {
            Destroy(child.gameObject);
        }

        // destroy the app model
        if (appModel != null)
        {
            Destroy(appModel.gameObject);
        }

        // disable the canvas
        appCanvas.enabled = false;
    }

    // called when an app icon button is clicked
    public void LaunchApp(string appPath)
    {
        try
        {
            // launch the app
            vrApps.LaunchApplication(appPath);

            // create a new RenderModel for the app
            appModel = new RenderModel(appPath);

            // set the canvas as the parent of the app model
            appModel.transform.SetParent(appCanvas.transform);

            // set the position and rotation of the app model
            appModel.transform.localPosition = Vector3.zero;
            appModel.transform.localRotation = Quaternion.identity;

            // enable the canvas
            appCanvas.enabled = true;
        }
        catch (System.Exception ex)
        {
            // show an error message
            Debug.LogError("Failed to launch app: " + ex.Message);
        }
    }
}

我尝试了 chat.openai.com 的建议，这对我有很大帮助，我还检查了是否有任何语法错误，对我来说看起来不错

RenderModel 类位于 Valve.VR.InteractionSystem 命名空间中。 您的 using 语句列表中缺少这个。
