Sort array by ascending numerical order

Question

How do I sort an array by ascending numerical order? I'm trying to create a high score script, and found sort() in w3schools. A Sort() is also in the Unity scripting reference, so I was wondering if it can still work with numbers rather than text.

Here is my code:

 private var HighScores : Array;
 function sortScore(a, b){
   return a - b;
 }
 
 function CheckHighScores(NewTime : Score){ 
   HighScores.Push(NewTime);
   HighScores.Sort(sortScore);
   if (HighScores.length>10){
     HighScores.Pop();
   }
 }

Thanks.

The Unity Scripting reference doesn't say there is an overloaded version of Array.Sort that takes a function type as a parameter. Now, maybe its undocumented, but that probably means you can't input a custom sorting method into Unity's sort class. You could change to generic List easily though and that does allow for a custom comparison.

 import System.Collections.Generic;
 
 private var HighScores = new List.<int>();
 
 function sortScore(a, b){
   return a - b;
 }
 
 function CheckHighScores(NewTime : Score){ 
   HighScores.Add(NewTime);
   HighScores.Sort(sortScore);
 }

Thanks, that got rid of a lot of errors. But it now gives me this: The best overload for the method 'System.Collections.Generic.List.Add(int)' is not compatible with the argument list '(Score)'.

Sorry I completely overlooked that. Your time should be an int not a score so it should look like:

 function CheckHighScores (NewTime : int) {

You can change the underlying type to score if you want to, but then you have to have a Score class and you need to modify the sort method slightly.
