I understand the concept of family. 
The question is can I do this:
I have 5 weapons, each have an instance var of AttackPower with different values.
I want to put them in a family. 
So everytime enemies get hit by the family. 
I want the family to be able to reach each weapon's individual AttackPower, to reduce enemies health based on it. 
Is it possible to do that?
Because up until now, I can only use family instance var, which means all 5 weapons will have the same amount of AttackPower.
