3 ways to reduce redundant code in your adobe flash actionscript 3 projects
There is 3 great ways to reduce redundant code in your actionscript 3 projects:
1) Aggregation
If objects A and B has same function, why not put that function on a separate object C and let both other objects call it from there.
2) Composition ie. inheritance
Put your redundant code to a class C and let your objects A and B inherit those methods from there.
3) Last but not least: include -statement
Sometimes good old include -statement is best way to go. Just put your code on separate file and include it where ever it’s needed. Quick, dirty and powerfull! 
Included code doesn’t even have to be full class or function, but any usefull bit of code will do.
