??? arrays inside arrays??

[xykudyax]

I needed some help here, i'm trying to order some arrarys... is it possible to use arrays inside arrays like in C?

array1 = [att1, def1, agl1, mag1, ID]
array2 = [att2, def2, agl2, mag2, ID]
array3 = [att3, def3, agl3, mag3, ID]

i want ot order them by the value in the agility (agl) slot.

in C i would have used arrays inside arrays, I don't know how to do in RGSS! ???

Thank you in advance,

It certainly is possible.  Here is an example:

array=[
   [att1, def1, agl1, mag1, ID],
   [att2, def2, agl2, mag2, ID],
   [att3, def3, agl3, mag3, ID]
]
array.sort!{|a,b|  a[2]<=>b[2]}

The sort! method sorts the array in place.  The two parameters, a and b, are two items
from the array to be compared.

thank you very much theres also something i wanted to ask then,

in the array:

array = [
   [12, 32, 11, 0, 77]
   [2, 26, 1, 12, 3]
   [1,98,54,22,89]
]

how do I refer to number 12?

is it array[1][3] ??
do you know were I can learn more about those things?
I know where to find ruby info but i heard some functions do not work in RGSS

array[0][0] Indexing starts with 0 and increases sequentially. And to learn more about Ruby/RGSS visit http://www.rmxp.org/forums/index.php?topic=1868.0
I'm not aware of any functionality that doesn't work on RGSS that works on Ruby. RGSS is built on top of Ruby after all.

To access it sequentially:

for i in 0...array.size
  array[i].each {|item| p item }
end

for i in 0...array.size
  for j in 0...array[i].size
    p array[i][j]
  end
end

array.each do |subarray|
  subarray.each do |item|
    p item
  end
end

Oh one last thing don't forget the comma's in between array elements.
array =
[
  [1, 2, 3, 4],
  [5, 6, 7, 8],
  [9, 10, 11, 12]
]

Good luck with it xykudyax! :afro:
