Re: learning by doing part 2 - tc game

I wanted to test this on a simple case, so I wrote the following:
------------------------------------------
def attack(target)
target -= 200
end

class A
def initialize(name, hp)
@name = name
@hp = hp
end

def hp()
@hp
end

def name()
@name
end

end

players = [] << A.new("test", 400)

attack(players[0].hp)

puts players[0].hp
------------------------------------------
The code runs, but the result is 400. As if the attack method did 
nothing.
What am I doing wrong?
