Unity自动替换字体脚本

前言

项目需要替换字体是件非常麻烦的事，需要一个个找Text组件。闲来无事写了个自动替换字体的脚本。也算用作抛砖引玉，利用此脚本的逻辑制作类似的功能，大大节约人力。

用法

将脚本放到Editor目录下，在Project项目面板下右键，选择Create->FontHelper即可创建出FontHelper。 FontHelper的监视面板如下图。 选择好字体后，点击预制体一键修改就可以修改所有的Prefab了。点击修改所有scene就是将挂到BuildSetting的scene中的字体全部修改。

代码

注意，引用的unity.linq是在assetstore下载的叫做LINQ to GameObject的免费插件。

using UnityEngine; using UnityEditor; using System.Linq; using UnityEngine.UI; using Unity.Linq; using UnityEditor.SceneManagement; [CreateAssetMenu(fileName = "FontHelper", menuName = "FontHelper")] public class MyFontHelper : ScriptableObject { [Space(10)] public Font font; [Space(10)] public bool isDebug; [Space(10)] bool isNeedSave; [CustomEditor(typeof(MyFontHelper))] public class MyHelper : Editor { public override void OnInspectorGUI() { var myHelper = target as MyFontHelper; base.OnInspectorGUI(); EditorGUILayout.Space(); if (GUILayout.Button("查看所有预制体使用到的字体")) { string[] guids = AssetDatabase.FindAssets(string.Format("t:{0}", "GameObject")); for (int i = 0; i < guids.Length; i++) { //转化路径 string assetPath = AssetDatabase.GUIDToAssetPath(guids[i]); //加载对象 GameObject root = AssetDatabase.LoadAssetAtPath<GameObject>(assetPath); foreach (var go in root.DescendantsAndSelf() .Where(n => n.GetComponent<Text>())) { if (myHelper.isDebug) { Debug.Log("Font:" + go.GetComponent<Text>().font.name + "   Path:" + assetPath + "  Name:" + root + "/" + go.name); } else { Debug.Log(go.GetComponent<Text>().font.name); } } } } EditorGUILayout.Space(); if (GUILayout.Button("预制体一键修改")) { int temp = 0; //修改总数量 //找到所有Project下GameObject，Prefab就是GameObject string[] guids = AssetDatabase.FindAssets(string.Format("t:{0}", "GameObject")); //对每个路径下的GameObject进行操作 for (int i = 0; i < guids.Length; i++) { //转化路径 string assetPath = AssetDatabase.GUIDToAssetPath(guids[i]); //加载对象 GameObject root = AssetDatabase.LoadAssetAtPath<GameObject>(assetPath); foreach (var go in root.DescendantsAndSelf() .Where(n => n.GetComponent<Text>())) { ++temp; if (myHelper.isDebug) Debug.Log(root.name + "下的" + go.name + "物体上的组件已被修改。"); go.GetComponent<Text>().font = myHelper.font; myHelper.isNeedSave = true; EditorUtility.SetDirty(go); } Debug.Log(string.Format("预制体修改完成！共修改{0}个Text组件。", temp.ToString())); if (myHelper.isNeedSave) { PrefabUtility.SavePrefabAsset(root); SaveAndRefresh(); myHelper.isNeedSave = false; } } } EditorGUILayout.Space(); if (GUILayout.Button("修改BuildSetting中的所有scene")) { // 遍历build setting中的场景 foreach (UnityEditor.EditorBuildSettingsScene S in UnityEditor.EditorBuildSettings.scenes) { //在built setting中被勾选 if (S.enabled) { //得到场景的名称 string name = S.path; //打开这个场景 UnityEditor.SceneManagement.EditorSceneManager.OpenScene(name); // 遍历场景中的GameObject // 注意FindObjectsOfTypeAll虽然会找到所有对象，但是也会找到场景中没有的东西，而且会出现重复查找的情况，最好是进行筛选一下 foreach (Text obj in Resources.FindObjectsOfTypeAll(typeof(Text))) { if (myHelper.isDebug) Debug.Log("scene name:" + name + "    object name:" + obj.name); obj.font = myHelper.font; EditorUtility.SetDirty(obj); } EditorSceneManager.SaveOpenScenes(); SaveAndRefresh(); } }; } EditorGUILayout.Space(); if (GUILayout.Button("修改选中目标及其子物体")) { var os = Selection.objects; foreach (var item in os) { GameObject go = item as GameObject; foreach (var g in go.DescendantsAndSelf().Where(_ => _.GetComponent<Text>())) { if (myHelper.isDebug) Debug.Log(g.name + "物体上的组件已被修改。"); g.GetComponent<Text>().font = myHelper.font; EditorUtility.SetDirty(g); } } SaveAndRefresh(); EditorSceneManager.SaveOpenScenes(); } void SaveAndRefresh() { AssetDatabase.SaveAssets(); AssetDatabase.Refresh(); } } } }
