Ruby: Sorting 2 arrays using values from one of them

Question

I\'m creating a simple game in ruby, and I have two arrays storing high score: $HS_Points and $HS_Names. I\'m saving high score in two files, and I wan

Answer 1

Don't store the names and the scores in separate variables; they're tied together, so their data should be tied togeher.

Try, say, $HighScores, which is an array of hashes with a :name element and a :value element, like:

$HighScores = [  
   { :name => "Bob", :score => 234 },
   { :name => "Mark", :score => 2 },   
]

Then you can add a high score:

$HighScores << { :name => "New Guy", :score => 50000 }

and then re-sort them and take the top 10 in one statement:

$HighScores = $HighScores.sort { |a,b| b[:score] <=> a[:score] }[0,10] 

This will still work if the scores are base-23 encoded. (but why are you doing that?)

You should probably also save them to a single file. To make that easier, consider using the Marshal module.
