👉前言

Rokid Unity OpenXR Plugin 是为Unity 开发者提供的在 YodaOS-Master 空间计算操作系统上开发空间计算应用的工具。它基于OpenXR 标准开发，帮助开发者在 YodaOS-Master 上进行空间构建、虚实交互、空间感知，并最终构建完整的空间应用。本篇内容可接我的上两篇内容：

博客将会介绍如何实现用Unity引擎开发Rokid主机的离线语言交互模型的操作。希望这篇博客对Unity的开发者有所帮助。大家好，我是心疼你的一切，不定时更新Unity开发技巧，觉得有用记得一键三连哦。欢迎点赞评论哦.下面就让我们进入正文吧 !

提示：以下是本篇文章正文内容，下面案例可供参考

👉一、效果实现

Rokid模拟离线语音交互模型

👉二、场景搭建

这个就不多说了，在上一篇的内容里新增的脚本和UI,这里只把新增的东西放上去 1.新增的UI视图如下：

2. Game视窗显示如下：

3. 环境配置跟着官网的文档配置即可文档链接 4. 配置 Maven 仓库地址视图如下：

5. 配置插件依赖视图如下：

👉三、代码实现

因为是继续上一篇的代码实现的，所以还需要稍微的修改一下

ModelData.cs 代码如下：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using Battlehub.RTHandles;

public class ModelData : MonoBehaviour
{
    public static ModelData instacne;

    public Transform carPrefab;
    public Transform cartemporary;   //临时的
    public PositionHandle positionHandle;
    public RotationHandle rotationHandle;
    public ScaleHandle scaleHandle;


    private void Awake()
    {
        instacne = this;
    }
    // Start is called before the first frame update
    void Start()
    {
        
    }
    /// <summary>
    /// 生成模型
    /// </summary>
    public void CreateModel()
    {
        if (cartemporary==null)
        {
            Transform transfo = Instantiate(carPrefab);
            cartemporary = transfo;
        }
       

    }
    /// <summary>
    /// 移动模型
    /// </summary>
    public void PosModel()
    {
        CloseJH();
        if (cartemporary != null)
        {
            cartemporary.GetComponent<PositionHandle>().enabled = true;
        }

    }
    /// <summary>
    /// 旋转模型
    /// </summary>
    public void RotModel()
    {
        CloseJH();
        if (cartemporary != null)
        {
            cartemporary.GetComponent<RotationHandle>().enabled = true;
        }

    }
    /// <summary>
    /// 缩放模型
    /// </summary>
    public void ScaModel()
    {
        CloseJH();
        if (cartemporary != null)
        {
            cartemporary.GetComponent<ScaleHandle>().enabled = true;
        }

    }
    /// <summary>
    /// 删除模型
    /// </summary>
    public void DesModel()
    {
        if (cartemporary != null)
        {
            Destroy(cartemporary.gameObject);
        }
    }

    public void CloseJH()
    {
        if (cartemporary != null)
        {
            cartemporary.GetComponent<PositionHandle>().enabled = false;
            cartemporary.GetComponent<RotationHandle>().enabled = false;
            cartemporary.GetComponent<ScaleHandle>().enabled = false;
        }
    }
   
}

离线语言的设置脚本如下代码：RecognitionVoice.cs

using Rokid.UXR.Module;
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.Android;
using UnityEngine.UI;

public class RecognitionVoice : MonoBehaviour
{
    private bool isInitialized ;
    public Text infoText;   //语音指令
    private void Awake()
    {
        if (!Permission.HasUserAuthorizedPermission("android.permission.RECORD_AUDIO"))
        {
            Permission.RequestUserPermission("android.permission.RECORD_AUDIO");
        }
    }
    // Start is called before the first frame update
    void Start()
    {
        InitializeVoiceControl();
    }
    /// <summary>
    /// 初始化语音控制
    /// </summary>
    private void InitializeVoiceControl()
    {
        if (!isInitialized)
        {
            ModuleManager.Instance.RegistModule("com.rokid.voicecommand.VoiceCommandHelper", false);
            OfflineVoiceModule.Instance.ChangeVoiceCommandLanguage(LANGUAGE.CHINESE);
            isInitialized = true;
        }
        AddVocies();
    }

    public void AddVocies()
    {
        OfflineVoiceModule.Instance.AddInstruct(LANGUAGE.CHINESE, "变成红色", "bian cheng hong se", this.gameObject.name, "OnReceive");
        OfflineVoiceModule.Instance.AddInstruct(LANGUAGE.CHINESE, "变成绿色", "bian cheng lv se", this.gameObject.name, "OnReceive");
        OfflineVoiceModule.Instance.AddInstruct(LANGUAGE.CHINESE, "恢复颜色", "hui fu yan se", this.gameObject.name, "OnReceive");
        OfflineVoiceModule.Instance.Commit();
    }
    public  void OnReceive(string msg)
    {
        infoText.text = msg;
        Debug.Log("-RKX- UXR-Sample:: On Voice Response received : " + msg);

        if (string.Equals("变成红色", msg) || string.Equals("Show blue", msg))
        {
            Changecolor(Color.red);
        }
        else if (string.Equals("变成绿色", msg) || string.Equals("Show green", msg))
        {
            Changecolor(Color.green);

        }
        else if (string.Equals("恢复颜色", msg) || string.Equals("Show white", msg))
        {
            Changecolor(Color.white);

        }
        else
        {
            Debug.Log("voice OnResponse: " + msg);
        }
    }

    void Changecolor(Color color)
    {
        if (ModelData.instacne.cartemporary!=null)
        {
            Transform transf = ModelData.instacne.cartemporary;
            Material[] MATS= transf.GetChild(0).GetComponent<MeshRenderer>().materials;
            MATS[0].color = color;
        }
        
    }

    private void OnDestroy()
    {
        OfflineVoiceModule.Instance.ClearAllInstruct();
        OfflineVoiceModule.Instance.Commit();
    }
}

3.RecognitionVoice.cs脚本挂载到如下图所示
