Flex 项目与 Actionscript 项目的优缺点? [英] Disadvantages of a Flex project vs an Actionscript project?

问题描述

我最近开始在 FlexBuilder 中制作游戏.该游戏目前是一个 Flex 项目.

I've recently started making a game in FlexBuilder. The game is currently a Flex project.

与仅使用 Actionscript 相比，使用 Flex 有什么缺点吗?

Is there any downside to using Flex as opposed to just Actionscript?

一个朋友的朋友告诉我 Flex 比 Actionscript 项目慢.我一直无法在互联网上验证这一点；这种说法有道理吗?

A friend of a friend told me that Flex is slower than an Actionscript project. I've been unable to validate this on the internet; is there any truth to that claim?

谢谢！

推荐答案

• 如果您正在开发游戏，则应该使用 ActionScript 项目.Flex 仅用于数据驱动的应用程序和用户界面.
• flex 编译器会生成大量中间代码来将 mxml 文件转换为 actionscript(如果使用 -keep 编译器选项进行编译，则可以查看这些文件).这段代码是合并到您的 SWF 中的 flex 框架，显着增加了大小.
• 创建一个带有文本字段(hello world")的 actionscript 项目和一个带有相同文本标签的 flex 项目.构建它们，转到它们的 bin-debug 文件夹并比较文件大小.虽然动作脚本只有几千字节，但 flex swf 至少有 100 KB.
• 就速度而言，由于 flex 框架位于 actionscript 之上，因此显然会有性能下降.
• Flex 的美妙之处在于可以轻松创建 UI 组件和开发经常与服务器通信的数据驱动应用程序.
• 除非确实需要，否则不要使用它.
• If you're developing a game, you should be using an ActionScript project. Flex is to be used only for data driven applications and user interfaces.
• The flex compiler generates a lot of intermediate code to convert mxml files into actionscript (you can view those files if you compile with -keep compiler option). This code, the flex framework incorporated to your SWF, adds significantly to the size.
• Create an actionscript project with a textfield ("hello world") and a flex project with a label with the same text. Build them, go to their bin-debug folders and compare the file sizes. While actionscript one is only a couple of kilobytes, flex swf would be at least a 100 kB.
• As far as speed is concerned, since the flex framework is sitting on top of actionscript, it obviously would have a performance downside.
• The beauty of flex lies in the easiness to create UI components and developing data driven applications that frequently communicates with the server.
• Don't use it unless you truly need it.
