Pass an array to a new instance of a class.

[Jonathan Allen]

I am having trouble passing values to an array of a new instance of the
class Item that I have created. The following codse does not fille the
flags array with the value 'container'.


class Item
attr_accessor :inum, :name, :description, :slot, :flags, :items

def initialize( inum, name, description, slot, flags, items )
@inum = inum
@name = name
@description = description
@slot = slot
@flags = []
@items = []
end

def is_container
return true if flags.include?(container)
end
end


Item.new("0007", "crate", "A large crate.\r\n", ":none", "container",
"")


However when I use the code below, I am able to add the value
'container' to the flags array.


$rooms[("0001")].item("crate").flags << "container"


My question is, how do I modify the first bit of code to allow passing
values to the array of the new instance of the class Item?

If you do not always pass an Array you can do

@items = []
@items << items

Thanks Robert. I didn't think about pushing the items into the array
from within the actual code for the class Item itself.

This worked just the way I was hoping. Thanks again!

=A0def is_container
=A0 =A0return true if flags.include?(container)
=A0end
end

Apart from all the other suggestions, you should change the container
above to "container".

@items<< items

Note though that the code above only appends a single Array to the Array
- it does not "push items into the array"! For that you need #concat as
I have shown.

Kind regards
