That's what I meant. I guess it wasn't clear from my initial code that I 
need writer, that is accessor.

Sorry if I confused anyone. It's just that I didn't want any duplication 
as Peter suggested, but then If I understand correctly I need either the 
writer or accessor to be able to change the values of instance 
variables.

What I meant was, that if omit the attr_accessor completely and only 
have methods for instance variables defined, then

player.hp -=20 does nothing.
