Re: Writing a game, trying to make dynamic loops

Hi!

Would you be happy accessing players by an array index?=20
eg. players[0].name would return player 1's name
players[2].score would return player 3's score etc.

Possibly not the best solution but I think it would work:

class Player
	def initialize(name)
		@name =3D name
	end
end

puts "How many players?"
players =3D Array.new(gets.to_i) #.to_i converts the string to an =
integer if possible

# players is now an array the size of entered number and will look like =
this if player entered '3' [nil, nil, nil]

# map! lets you alter array elements and goes through them exactly as =
.each does
# have a look at the documentation for more info

n =3D 1
players.map! { |e|
	puts "Name of player #{n}?"
	e =3D Player.new(gets.chomp()) #chomp strips off the newline =
character
}

players[0] will give you access to your first player object
players[1] etc.

you could use players[1].name
or players[2].score to use your player methods once you've defined them



# inspecting the array gives you a list of Player objects

# you could instead use hashes to access your objects with some tweaks =
to the assignment process

# also are you sure you want objects named after what is set as the =
player name?
