Calling data from data class?

[Sobeman459]

I have this data class

#===================================================================================

#    Bakugan Data Structure

What i want to be able to do i use

Player = Struct.new(:b1, :b2, :b3, :g1, :g2, :g3, :a1, :a2, :a3)

well just the b1 b2 and b3 to call just the idea from the Bakugan Data Class if that possible and if so how would i do it? Basicly and eventully the player will pick 3 different bakugan objects from a menu to use in a battle but i cannot do that tile i know how to call it. Any help is greatly appreciated. Thank you.

Hi

p [Player.b1,Player.b2,Player.b3]

Struct is a class. Each parameter is an attribute.

best regards,

That wouldn't work berka.

Struct is a class which is used for creating other classes.
The idea is probably to have something similar to structs in C++
Here is an example of how you can do it:
[rgss]Player_Class = Struct.newb1, :b2, :b3, :g1, :g2, :g3, :a1, :a2, :a3)
player_object = Player_Class.new(1, 5, 42, nil, nil, nil, nil, nil, nil)
p player_object.b1, player_object.b2, player_object.b3
[/rgss]



I can see you have created a global variable called $data_players. I suggest you use that to get a reference to a player.
You do not create any players in what you show us, but that's alright.
I personally prefer creating class methods which you can use to retrieve the players rather than using global variables.

I admit I am not really sure what you have problem with.
You have no problems creating Bakugan and card instances. It's the same procedure for the player.
Is it that you want to change the values at a later point?

*hugs*

Sorry... I misread
I believed he had used struct as:

Struct.new("Player_Class",b1...)

Structs is a good way for your system, but this is more simple:

class Player

  def initialize(*args)

    self.class.class_eval("attr_accessor :#{args.join(", :")}")

  end

end

About your $data_player you should use instances:

$data_player ||= {}

instance=Player.new("id","atk","def")

instance.id=251

$data_player[instance.id]=instance
