有人知道“World”是否被保留或是以这个名称建立了类吗？ 当我尝试构造我创建的World类时，它会抛出编译错误：
1136: Incorrect number of arguments. Expected 2.
但我已经检查了无数次，没有任何要求参数的地方，所有的包命名、变量类型等都是正确的，但它仍然抛出这个愚蠢的错误:/ 自己尝试一下，你会发现它确实有问题...或者我太蠢了?
当我尝试在World类中调用init函数时，它会抛出以下错误：
1061: Call to a possibly undefined method init through a reference with static type World.
天哪..
我也遇到了这个问题。我认为从FlashPlayer 10（可能是10.1，但不能确定）开始保留了它。我不得不通过在引用我的World类时使用完整的包名来解决它。
var myWorld:com.foo.World = new com.foo.World();
丑陋，但它能用！
还有其他几种可能性：
您是否正在使用Flex/FlashBuilder，并导入SWC？这些可以公开类而不揭示源代码。
或者您是从FLA编译的吗？在这种情况下，可能会有一个库符号导出到一个与您的名称冲突的ActionScript类。
另一种可能性是您正在使用的Flash编译器（无论是FlashPro还是FlashBuilder）已经错误地缓存了您之前创建的类定义。我以前遇到过这个错误几次。尝试进行项目/清理（在FlashBuilder中），或者如果您绝望了，请创建一个新项目。
你的源代码路径中必须有另一个名为 World 的类。查看你的导入。
如果需要避免与其他地方的 World 类混淆，请输入完整的包路径：
var w:my.package.World = new my.package.World();
我认为你应该检查构造函数中所需的参数，并通过将 = null 或其他内容传递给构造函数使它们变成可选的。
当你在库中放置一个具有构造函数中必需参数的符号时，就会出现这种“错误”。
package com.myworld
{
public class World
{
public function World(parameter1:int = null, parameter2:String = null )
{
}
}
}
这可能有点困难，但请尝试删除您的ASO文件（控制台>删除ASO文件），然后重新编译。
如果这不起作用，我唯一建议的是重建您的项目，在每次导入一个或一组类时测试此问题。这种方法应该能够确保您至少找到问题的来源。
以下文档类在Adobe Flash CS5中针对Flash Player 10.1.53.64（10.1）完全编译和执行：
package
{
import flash.display.Sprite;
import flash.events.Event;
public class World extends Sprite
{
public function World()
{
addEventListener(Event.ADDED_TO_STAGE, init);
}
private function init(evt:Event):void
{
removeEventListener(Event.ADDED_TO_STAGE, init);
trace("World Document Added To Stage");
}
}
}
我刚刚自己检查了一下，即使这是一个旧帖子，已经有人回答了。 原因是我通过搜索AS3中保留关键字列表找到了这篇文章。
"World"关键字不是保留的 :) 哎呀...
这是我迄今为止在AS3中发现的保留单词/关键字列表： 如果您编辑此列表，请留下评论/来源...谢谢 有时相同的关键字可能会在不同类别的列表中出现两次...
