Unity 处理预设中的中文

需求由来

• 项目接入越南版本

需要解决的文本问题

• 获取UI预设Label里面的中文(没被代码控制)提供给越南
• Label里面的中文替换成越南文

解决流程

• 迭代获取Assets目录下所有文件
• 获取所有的.prefab预设文件
• 加载预设文件
• 获取预设下所有的UILabel组建
• 判断UILabel中的值是否为中文

• 把所有的中文实例化成文本

• 替换成越南文
• 保存实例化对象为预设文件

• 销毁实例化对象

实现代码

• 获取UI预设Label里面的中文

[MenuItem("检查预设中文并且生成文本")]
    static void CheckChinesePrefabsAndSerialization()
    {
        List<string> paths = GetAllFilePaths();

        List<string> prefabPaths = GetAllPrefabFilePaths(paths);

        if (prefabPaths == null)
        {
            return;
        }

        List<string> text = new List<string>();

        for (int i = 0; i < prefabPaths.Count; i++)
        {
            string prefabPath = prefabPaths[i];

            //修改路径格式
            prefabPath = ChangeFilePath(prefabPath);

            AssetImporter tmpAssetImport = AssetImporter.GetAtPath(prefabPath);

            GameObject prefab = AssetDatabase.LoadAssetAtPath<GameObject>(tmpAssetImport.assetPath);

            if (prefab == null)
            {
                continue;
            }

            UILabel[] uiLabels = prefab.GetComponentsInChildren<UILabel>();

            for (int j = 0; j < uiLabels.Length; j++)
            {
                UILabel uiLabel = uiLabels[j];

                if (IsIncludeChinese(uiLabel.text))
                {
                    Debug.LogError(string.Format("路径:{0} 预设名:{1} 对象名:{2} 中文:{3}", prefabPath, prefab.name, uiLabel.name, uiLabel.text));
                    text.Add(uiLabel.text);
                }
            }

            //进度条
            float progressBar = (float)i / prefabPaths.Count;
            EditorUtility.DisplayProgressBar("检查预设中文", "进度 ：" + ((int)(progressBar * 100)).ToString() + "%", progressBar);
        }

        SerializationText(Application.dataPath + "/中文.txt", text);

        EditorUtility.ClearProgressBar();

        AssetDatabase.Refresh();

        Debug.Log("完成检查预设中文并且生成文本");

• Label里面的中文替换成越南文

            GameObject obj = Instantiate(prefab) as GameObject;

            UILabel[] uiLabels = obj.GetComponentsInChildren<UILabel>();

            bool isChange = false;

            for (int j = 0; j < uiLabels.Length; j++)

        StringBuilder stringBuilder = new StringBuilder();

        for (int i = 0; i < content.Count; i++)

            stringBuilder.AppendLine(content[i]);
