I published a new article at Community MX that covers the Object.Watch and object.Unwatch features in Flash.
“My last article covered a lesser-known feature of the native Object class in Flash for resolving undefined properties and methods: Resolving Undefined Methods and Properties Within a Flash Object. This article is also going to explore a lesser-known feature of the Object class called watch/unwatch. The feature allows you to monitor an object’s properties for changes. In this article we examine the feature and show how to use it. We will also cover a real-world example of how this feature could be used to make your development efforts easier.”
