About Instance Variables from Windows ...

[The Good King]

How do I call an instance variable from a window? like @commands?

To elaborate, I added a style argument to Window_Command to add the ability for a command window to display options in alternating order and the display of it works fine.

Spoiler: what i mean by 'alternating order'

NORMAL DISPLAY
-----------------
1
2
3
4

ALTERNATING DISPLAY
----------------------
1 2
3 4

Now I have to recode the cursor, which brings up the problem with columns. In the original there is only ever one column of choices, so of course the original makers had it = 1 w/o thought to add functionability for aditional columns. However, in my model there are two. I created a @style instance variable for the argument style in Window_Command, so how do I bring that variable into Window_Selectable to vary the # of columns?

woops...hit quote instead of modify........ :-[

 

[khmp]

class Window_Command < Window_Selectable
  attr_accessor :commands
end

However you are trying to gain access to this data from an ancestor of the window. So in the ancestor create a method that takes in the array of commands than from the child invoke the method.

class Window_Selectable < Window_Base
  def do_stuff(commands)
    # Do work involving the commands
  end
end

That will let you get to that instance variable while the Command_Window exists. But if you are trying to access it from a child's data from the ancestor perhaps the design should change to reflect a new window rather than a change of the existing.

just wait a moment... I think the solution is quite simple...

edit:
OK, this may be your answer...

Instructions?

Well, you may need to create a window like this...
# here you would need all the commands you need, in this case you would need 4 of them.
@command_window = Window_Command2.new(160, [s1, s2, s3, s4])
# the rest is identical to the common update process and disposal of commands windows.
