Unity 开发常用功能

从本地读取文件

/// <summary>
    /// IO读取
    /// </summary>
    /// <returns></returns>
    private IEnumerator ReadData()
    {
        string readData;
        string fileUrl = Application.streamingAssetsPath + "/FileReadTest.json";
        //读取文件
        using (StreamReader sr = File.OpenText(fileUrl))
        {
            //数据保存
            readData = sr.ReadToEnd();
            sr.Close();
        }
        //返回数据
        Debug.Log("打印读取的技能Json：" + readData);
        yield return null;
    }

从网络或者本地读取文件

//从网络或者本地读取文件
private IEnumerator GetData(string url)
    {
       // var uri = new System.Uri(Path.Combine(Application.streamingAssetsPath, //"FileReadTest.json"));
        UnityWebRequest www = UnityWebRequest.Get(url);
        yield return www.SendWebRequest();

        if (www.isNetworkError || www.isHttpError)
        {
            Debug.Log(www.error);
        }
        else
        {
            string jsonStr = www.downloadHandler.text;
            Debug.Log("打印读取的技能Json：" + jsonStr);
        }
    }
