长春网站制作建设seo sem是什么
具体流程：
- 找到工程中使用到的所有字体
- 找到工程和场景中包含Text的所有对象
- 展示要替换的字体名字让用户选择
- 通过用户选择的字体，展示响应的物体对象
- 一键替换
通过AssetDatabase.FindAssets找到工程中包含的所有字体：
private List<string> FindAllFonts(){List<string> list = new List<string>();// 获取所有字体文件string[] fontGUIDs = AssetDatabase.FindAssets("t:Font");foreach (string fontGUID in fontGUIDs){string fontPath = AssetDatabase.GUIDToAssetPath(fontGUID);Font font = AssetDatabase.LoadAssetAtPath<Font>(fontPath);list.Add(font.name);}list.Add("Arial");//默认字体添加进去return list;}通过AssetDatabase.FindAssets找到工程中的所有预制体
private List<GameObject> GetAllPrefabByAssetDatabase(params string[] path){List<GameObject> _prefabList = new List<GameObject>();string[] _guids = AssetDatabase.FindAssets("t:Prefab", path);string _prefabPath = "";GameObject _prefab;foreach (var _guid in _guids){_prefabPath = AssetDatabase.GUIDToAssetPath(_guid);_prefab = AssetDatabase.LoadAssetAtPath(_prefabPath, typeof(GameObject)) as GameObject;_prefabList.Add(_prefab);}
#if UNITY_2020_1_OR_NEWERText[] texts = GameObject.FindObjectsOfType<Text>(true);foreach (var text in texts){_prefabList.Add(text.gameObject);}
#elseScene activeScene = EditorSceneManager.GetActiveScene();GameObject[] allObjectsInScene = activeScene.GetRootGameObjects();foreach (var obj in allObjectsInScene){Text[] texts = obj.GetComponentsInChildren<Text>(true);foreach (var text in texts){_prefabList.Add(text.gameObject);}}
#endifreturn _prefabList;}过滤没有含Text组件的对象
private List<GameObject> FilterNoTextPrefabs(){List<GameObject> templist = new List<GameObject>();Dic_Font_Prefabs.Clear();foreach (var prefab in prefabs){Text[] texts = prefab.GetComponentsInChildren<Text>(true);if (texts.Length != 0){foreach (var text in texts){if (text.font != null){if (!Dic_Font_Prefabs.ContainsKey(text.font.name)){Dic_Font_Prefabs.Add(text.font.name, new List<GameObject>());//根据Font类型，添加一个Text集合到字典中}if (!Dic_Font_Prefabs[text.font.name].Contains(prefab)){Dic_Font_Prefabs[text.font.name].Add(prefab);}if (!templist.Contains(prefab)){templist.Add(prefab);//包含该Text的预制体添加到集合中}}}}}return templist;}最后，用户选择完要替换的字体，选择开始替换即可。
TextMeshPro跟Text是一个道理，只需要把代码中响应的Text和Font改为TextMeshProGUI和FontAssets即可。
