U_根据脚本模板创建脚本

脚本内容：

public class MenuTool {
    private static string path = "Assets/TemplateClass.txt";
    
    [MenuItem("Assets/创建模板类")]
    public static void GanerateTemplateClass() {
        // 获取选中的文件名称
        var obj = Selection.objects;
        for (var i = 0; i < obj.Length; i++) {
            var o = obj[i];
            // 获取路径
            var path = AssetDatabase.GetAssetPath(o.GetInstanceID());
            // 获取完整文件名
            var fileName = Path.GetFileName(path);
            // 筛选出文件名称后面作为类替换
            fileName = fileName.Substring(0, fileName.IndexOf('.'));
            if (path.EndsWith(".txt")) {
                // 字节流读取
                var streamReader = new StreamReader(path);
                var log = streamReader.ReadToEnd();
                streamReader.Close();

                // 替换类名
                log = Regex.Replace(log, "#ClassName#", fileName);
                var createPath = $"Assets/{fileName}.cs";

                // 写入文件
                var streamWriter = new StreamWriter(createPath, false, new UTF8Encoding(true, false));
                streamWriter.Write(log);
                streamWriter.Close();

                AssetDatabase.ImportAsset(createPath);
                Debug.Log(log);
            }
        }
    }
}v

示例 txt 文件

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class #ClassName# : MonoBehaviour {
    void Start() {
        
    }

    void Update() {
        
    }
}
