Unity 编辑器脚本：错误 CS1525：意外符号 `<internal>'

Question

我正在制作一款塔防游戏。在第一个版本中，我使用简单的文本格式来表示关卡。这是非常基本的，每次我添加新的级别属性时都必须维护解析过的内容。我发现了序列化和写入二进制文件的加载和保存。为此，我有一个可序列化的类，如下所示：

[Serializable]
public class LevelData {
public string filename;
public List<List<Tile>> grid;
public List<Vector2> waypoints;
public int width;
public int length;

public Vector2 startPos;
public Vector2 finishPos;

public List<TowerInfo> towers;
public List<WaveData> waveChain;
}

现在我想在我的 LevelManager 中添加一个编辑器脚本，它解析旧的文本文件格式并将它们转换为二进制格式。这是我的编辑器脚本：

using System;
using System.Collections;
using System.Collections.Generic;
using System.IO;
using System.Runtime.Serialization.Formatters.Binary;
using UnityEditor;
using UnityEngine;

[CustomEditor(typeof(LevelManager))]
[CanEditMultipleObjects]
public class LevelManagerEditor : Editor {
public string levelFilename;

public override void OnInspectorGUI() {
    DrawDefaultInspector();
    if(GUILayout.Button("Load level " + levelFilename + " and serialize")) {
​        LevelData levelData;
        ParseFromFile(out levelData);
        Debug.Log("Parsing " + levelFilename + " successful!");
        SaveLevel(levelData);
        Debug.Log("Saved serialized level");
    }
}
private void ParseFromFile(out LevelData levelData) {
    levelData = new LevelData();
    levelData.filename = levelFilename;
    System.IO.StreamReader file = new System.IO.StreamReader(levelFilename + ".txt");

    string line;
    int y = 0;
    while ((line = file.ReadLine()) != null) {
        if (line[0] == '#') break;
        List<Tile> row = new List<Tile>();
        for (int x = 0; x < line.Length; x++) {
            switch(line[x]) {
                case '.':
                    row.Add(Tile.NORMAL_BRICK);
                    break;
                case 'P':
                    row.Add(Tile.PATH_BRICK);
                    break;
                case 'S':
                    row.Add(Tile.START_BLOCK);
                    levelData.startPos = new Vector2(x, y);
                    break;
                case 'F':
                    row.Add(Tile.FINISH_BLOCK);
                    levelData.finishPos = new Vector2(x, y);
                    break;
                default:break;
            }
        }
        levelData.grid.Add(row);
        levelData.width = row.Count;
        y++;
    }
    levelData.length = y;
    while((line = file.ReadLine()) != null) {
        levelData.waypoints.Add(ParseWaypoints(line));
    }
    file.Close();
}
private Vector2 ParseWaypoints(string line) {
    string[] tokens = line.Split(' ');
    return new Vector2(int.Parse(tokens[0]), int.Parse(tokens[1]));
}
private void SaveLevel(LevelData levelData) {
    string pathToLevel = Application.persistentDataPath + "/" + levelData.filename + ".dat";
    FileStream file = File.Create(pathToLevel);
    BinaryFormatter bf = new BinaryFormatter();
    bf.Serialize(file, levelData);
}
}

这是编译器错误： Assets/Tower Defense Assets/Scripts/Utilities/LevelManagerEditor.cs(17,5): 错误 CS1525: Unexpected symbol `'

当我双击它时，它会将我指向 OnInspectorGUI() 中的 LevelData levelData; 声明

我不明白这个错误。请帮忙。谢谢:)

我想通了。我在那条线上有一个无法打印的字符。我不得不删除那行并重写它。
