Unity 批量将图片从默认类型改为Sprite类型

先将该脚本放到Editor目录下

如何使用:选中目录,然后点击Tool里面的批量修改按钮

using System;
using UnityEngine;
using UnityEditor;
using System.IO;
using System.Linq;/// <summary>
/// 此工具可以批量将图片类型修改为精灵
/// </summary>
public class TextureTypeModifier
{[MenuItem("Tools/批量修改图片为Sprite(2D and UI)", false, 20)]private static void ConvertSelectedFolderToSprite(){// 获取选中的文件夹路径string folderPath = AssetDatabase.GetAssetPath(Selection.activeObject);if (!AssetDatabase.IsValidFolder(folderPath)){EditorUtility.DisplayDialog("错误", "请选择一个文件夹！", "确定");return;}// 递归获取所有图片文件string[] imagePaths = Directory.GetFiles(folderPath, "*.*", SearchOption.AllDirectories).Where(file => file.EndsWith(".png", StringComparison.OrdinalIgnoreCase) ||file.EndsWith(".jpg", StringComparison.OrdinalIgnoreCase) ||file.EndsWith(".jpeg", StringComparison.OrdinalIgnoreCase)).ToArray();int modifiedCount = 0;// 批量修改foreach (string imagePath in imagePaths){if (imagePath.EndsWith(".meta")) continue;TextureImporter importer = AssetImporter.GetAtPath(imagePath) as TextureImporter;if (importer != null&& importer.textureType==TextureImporterType.Default && importer.textureType != TextureImporterType.Sprite){importer.textureType = TextureImporterType.Sprite;importer.spriteImportMode = SpriteImportMode.Single;importer.mipmapEnabled = false;importer.SaveAndReimport();modifiedCount++;}}AssetDatabase.Refresh();EditorUtility.DisplayDialog("完成", $"已将 {modifiedCount} 张图片转换为 Sprite(2D and UI)\n目录: {folderPath}", "确定");}// 验证菜单项是否可用（仅当选中文件夹时显示）[MenuItem("Tools/批量修改图片为Sprite(2D and UI)", true, 20)]private static bool ValidateConvertSelectedFolderToSprite(){return Selection.activeObject != null && AssetDatabase.IsValidFolder(AssetDatabase.GetAssetPath(Selection.activeObject));}
