Unity中咱们经常对字体做Create Editable Copy，虽然已经非常方便了，但是实际使用场景中，有时候会有不方便的地方。
已经不能忍了……
咱们脚本搞定这事，具体实现后效果 1. 用配置文件指明需要使用的font name，，font size，导出的字符集内容 2. 根据配置文件Create Editable Copy，同时保证场景中已存在的组件不丢失字体
一、添加Editor脚本：using UnityEditor;using UnityEngine;using UnityEngine.UI;using Systemusing System;using System.IO;public class CreateEditableCopyFont{[MenuItem (“Assets/Create Editable Copy Font”)]static void CreateFont (){TextAsset sourceTextAsset = null;try {sourceTextAsset = (TextAsset)Selection.activeObject;} catch (InvalidCastException e) {Debug.Log (“Selected Object is not a txt file: ” + Environment.NewLine + e.Message);}if (sourceTextAsset == null) {EditorUtility.DisplayDialog (“No Config selected”, “Please select a TxtFile Config…\nSuch as Exsample.txt:\nname=Assets/GameAssets/Fonts/impact.ttf,size=40\n123456789abcdefghijk”, “Cancel”);return;}int targetFontSize;string sourceFontPath, targetFontPath, targetFontCharacters = “”;try {string sourceConfigPath = AssetDatabase.GetAssetPath (Selection.activeObject);string[] sourceConfigInfos = sourceTextAsset.text.Split (‘\n’);string headInfo = sourceConfigInfos [0];string[] headInfos = headInfo.Split (‘,’);sourceFontPath = headInfos [0].Split (‘=’) [1];targetFontPath = sourceConfigPath.Replace (“.txt”, “_copy”);targetFontSize = int.Parse (headInfos [1].Split (‘=’) [1]);for (int i = 1; i < sourceConfigInfos.Length; i++) {targetFontCharacters += sourceConfigInfos [i];}} catch (Exception ex) {EditorUtility.DisplayDialog (“Config Error”, “The config header data error…”, “Cancel”);return;}// 重新生成字体文件会导致场景中已存在的丢失，// 所以需要生成后再次赋值string[] targetFontPathInfos = targetFontPath.Split (‘/’);string textCheckName = targetFontPathInfos [targetFontPathInfos.Length – 1];List<Text> listTexts = new List<Text> ();foreach (Text text in UnityEngine.Object.FindObjectsOfType(typeof(Text))) {if (text.font.name == textCheckName) {listTexts.Add (text);}}UnityEngine.Object f = AssetDatabase.LoadMainAssetAtPath (sourceFontPath);string path = AssetDatabase.GetAssetPath (f);TrueTypeFontImporter fontImporter = AssetImporter.GetAtPath (path) as TrueTypeFontImporter;fontImporter.fontTextureCase = FontTextureCase.CustomSet;fontImporter.customCharacters = targetFontCharacters;fontImporter.fontSize = targetFontSize;fontImporter.SaveAndReimport ();AssetDatabase.Refresh ();Font font = fontImporter.GenerateEditableFont (targetFontPath);foreach (Text item in listTexts) {item.font = font;}// 还原ttf设置fontImporter.fontTextureCase = FontTextureCase.Dynamic;fontImporter.SaveAndReimport ();AssetDatabase.Refresh ();System.GC.Collect ();}}二、添加配置文件
impact_40.txt
name=Assets/HEGameLib/Examples/Fonts/impact.ttf,size=you want export.
注意，配置文件我弄的很简单，第一行是使用的原字体和大小，第二行开始是你的需要导出的字符集。
将该文件放到你需要生成字体的目录，比如：Assets/GameAssets/Fonts/ 下。
三、生成字体
右键第二步中放入的配置文件，在弹出菜单中点击 Create Editable Copy Font 该目录下会生成所需字体。
再次生成该字体，场景中已存在的字体不会丢失。

看着你手中的戒指，你说，你可以把它取下来吗？
