Flash 开发、Flash 语言 (AS2/3) 和 Flash IDE 的隐藏功能/技巧 [英] Hidden features/tricks of Flash development, Flash language (AS2/3), and Flash IDE

问题描述

伙计们，我非常惊讶 隐藏功能系列 我一直在现在跟踪一段时间.

Guys, I am thoroughly surprised that there is no Flash Hidden Features post yet in the Hidden Features series that I've been tracking for a while now.

最近有一个 AS3/Flex 一个，但它不是很活跃，我当我在这里说 Flash 时，并不完全是指 AS3.

There is a recent AS3/Flex one but it's not very active and I don't exactly mean just AS3 when I say Flash here.

隐藏功能系列非常适合刚接触某种语言的人.它在一个地方展示了绳索和某些有价值的技巧.我认为这是一个绝妙的主意.即使是专家有时也会发现他们从未听说过的技巧.

The Hidden Features series is great for people who are new to a certain language. It shows the ropes and certain valuable tricks, all in one place. I think it's a brilliant idea. Even experts sometimes find tricks they'd never heard about.

当我开始使用 Flash 时，与其他编程语言相比，Flash IDE 和 Flash 的奇怪概念让我大吃一惊.

When I started with Flash, I was taken aback by the Flash IDE and odd concepts of Flash, compared to other programming languages.

那么，这里是:Flash 作为一种语言 (AS2/3) 和 Flash 有哪些隐藏功能?IDE?

So, here goes: what are some hidden features of Flash as a language (AS2/3) and the Flash IDE?

让乐趣开始吧.

推荐答案

[Flash IDE]

[Flash IDE]

这不是一个功能，而是一个陷阱.为 FLA 指定文档类时，编译器不会对该类进行子类化，而是修改它.

This isn't a feature as much as it is a gotcha. When specifying a document class for an FLA, the compiler does not subclass that class, it modifies it.

当您有多个具有相同文档类的 SWF 时，这会导致问题，所有这些都被加载到另一个 SWF 中(因为两个同名的类不能并排加载到同一个应用程序域中).这导致第一个被加载，第二个使用第一个修改后的类，产生奇怪的错误(如你所想).

This can cause problems when you have several SWFs with the same document class, all being loaded into another SWF (since two classes with the same name cannot be loaded side-by-side into the same application domain). It results in the first being loaded and the second using the first's modified class, producing weird errors (as you can imagine).

解决方案是:

• 为子类化文档类的每个 FLA 创建一个代理类
• 将每个 SWF 加载到新的子应用程序域中
