Sorting Weapons by id AND element....

[Daniel]

I am attempting to sort an array of weapons by id AND element. For example, all weapons with an element of 13 would be grouped together in the array, but be sorted by id within that group. Then next would come all the element 14s sorted by id. So, I have this slice of code:

@data.sort! {|a, b|

        for i in 13..18

          if a.element_set.include?(i)

            item_a = i - 12

          end

          if b.element_set.include?(i)

            item_b = i - 12

          end

        end

        item_a <=> item_b

      }

It sorts fine by element. How would I implement ids into the picture? Thanks in advance.

Okay, well this works:

@data.sort! {|a, b|

        for i in 13..18

          if a.element_set.include?(i)

            item_a = (i - 12) * 300

            item_a += a.id

          end

          if b.element_set.include?(i)

            item_b = (i - 12) * 300

            item_b += b.id

          end

        end

        item_a <=> item_b

      }

However, something tells me that there is a more "professional" way to do it. Anyone got any ideas/know how?
