Colleagues have recommended a flash debugging tool to me, it is really a good thing!
You can list objects and members of all levels of SWF in the run, which can dynamically perform the AS command, dynamically obtain and change the value of each variable and object's properties ...
In short, everyone will know, a word: strong.

// ps: Discussed with colleagues, it should be communication between the LocalConnection for SWF.
