使用 Flutter Flame 引擎时出现 XmlParseException 错误

Question

我正在使用 Flame 游戏引擎在 Flutter 中创建一个游戏我在平铺的帮助下创建了一个关卡。当我运行模拟器中的应用程序时，出现以下错误。

[log] Error while loading Game widget
[log] XmlParserException (XmlParserException: "<" expected at 1:1)
[log] #0      new XmlDocument.parse
package:xml/…/nodes/document.dart:35
The following XmlParserException was thrown building FutureBuilder<void>(dirty, state: _FutureBuilderState<void>#1f3ee):
"<" expected at 1:1

这是代码

主要Class:

import 'package:flutter/material.dart';
import 'package:flame/game.dart';
import './game/game.dart';

void main() {
  runApp(const MyApp());
}

// Todo: Use this!
// final _game = SimplePlatformer();

class MyApp extends StatelessWidget {
  const MyApp({Key? key}) : super(key: key);

  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: Scaffold(
        body: GameWidget(game: SimplePlatformer()),
      ),
    );
  }
}

SimplePlatformer class:

import 'package:flame/flame.dart';
import 'package:flame/game.dart';
import 'package:flame_tiled/flame_tiled.dart';

class SimplePlatformer extends FlameGame {
  @override
  Future<void>? onLoad() async {
    await Flame.device.fullScreen();
    await Flame.device.setLandscape();

    final level = await TiledComponent.load('level1.tmx', 
    Vector2.all(32));
    add(level);
    return super.onLoad();
  }
}

Level1.tmx 文件截图

Spritesheet.tsx 文件截图

Answer 1

看起来你的 XML-file 已经损坏，尝试从 Tiled re-export 它并确保你选择在导出文件中嵌入 tilesets 这样 tmx 文件就不会引用外部文件。
