wow插件开发

按照网上提供的资料,我在AddOns下面的建立一个hello文件夹,并在文件夹中建立了如下三个文件:
A. hello.toc
## Interface: 20400(最新版本2.4.2)
## Title: Hello World
## Notes: The obligatory hello world script – WoW-style!
## OptionalDeps:
## Dependencies:
hello.xml

B.hello.xml
<Ui xsi:schemaLocation="http://www.blizzard.com/wow/ui/">
<Script file="hello.lua"/>
<!-- Frame to handle all core events -->
<Frame name="hello_core">
<Scripts>
<OnLoad>
this:RegisterEvent("VARIABLES_LOADED");
</OnLoad>
<OnEvent>
if (event == "VARIABLES_LOADED")
then hello_initialize();
end
</OnEvent>
</Scripts>
</Frame>
