Variable Change Detection/Event

[Inverness]

I was hoping there was some way to detect when a variable is changed, through an event I would prefer, something like onVariableChange(varname, newvalue, oldvalue) or something. The reason for this is that I wish to sync a serverside and clientside object without using a loop to detect a change so I can get data on clientside without the use of client flags since those can be messed up too easily.

I figure something like this might exist already with the way Gui Controls act.

By the way, still want custom object types, would make my work a whole lot easier and cleaner. Made a system to mimic it but I prefer the genuine article.
