Like I said, the environment is a standalone environment only used by the addon, it has no effect to the global environment. Loading a file would run it as a function, change the function's environment will only affect it's content

Lua Code:
  1. a = 100
  2.  
  3. function testenv()
  4.     setfenv(1, {})
  5.  
  6.     a = 200
  7. end
  8.  
  9. testenv()
  10. print(a) -- still is 100

And also an addon can have multi-modules, so each module can handle system event for their own. This won't set a meta-table to the global environment, the real job is like :

Lua Code:
  1. local _M = Scorpio("MyAddon.Module")
  2.  
  3. Scorpio.__SystemEvent__()
  4. function _M.UNIT_HEALTH(unit)
  5. end

Also _M:RegisterEvent(xxx, handler) can be used by those moduels. the reason use attribute is it can combine several information :

Lua Code:
  1. __Thread__()
  2. __BigWigsEvent__ "BigWigs_EnableFriendlyNameplates"
  3. __DBMEvent__ "BossMod_DisableFriendlyNameplates"
  4. function UpdateFriendlyNameplates()
  5. end

你的问题是,为什么我要用OOP,但实际上OOP用在WOW的任何地方,你用CreateFrame出来的元素,也是在用OOP,blz自己就有一套复杂的继承体系,实际OOP的使用非常广泛,只不过可能像我这样着重提出的很少罢了,但总的来说,使用OOP系统提供的类型并非是一个困难的问题吧。

定义类型是相对过程式编程较为复杂的问题,这点对于普通插件作者来说,的确是很难接受的,因为意味着思维方式的变化,OOP更容易被现实中有对应经验的人接受,所以对PLoop的态度一般是两极分化的。但我一开始也说明,Scorpio这个框架不需要作者去熟悉PLoop。这个框架主体思路是提供便利和固化的开发方式,而并非要求你自己去学习如何制作类型。

如果要进一步说明,为什么我要在wow里面使用PLoop,而不是更轻量级的系统,更多原因是它很全面,基于它我能更快速的组建上层应用框架。但重申一句,我推荐给普通作者的是Scorpio,而非PLoop,即便在现实生活的工作中,我提供给其他人的也会是上层框架的应用,而不会让他们过多接触底层的东西。
