I'm trying to sort an array in Unity by name, using Array.Sort()
.
I've been reading as much as I can but still can't adapt it into my little project here. Here is what I have so far:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
using System;
public class UIController : MonoBehaviour, IComparable<Slot>
{
public static UIController instance;
public Text uiMessageBox;
public Slot[] slots;
private void Awake()
{
if (instance == null)
instance = this;
else
Destroy(this);
DontDestroyOnLoad(this);
slots = FindObjectsOfType<Slot>();
Array.Sort(slots, ); // HELP: NOT SURE WHAT TO PUT HERE
}
public int CompareTo(Slot other)
{
return this.name.CompareTo(other.name);
}
}
Note, I deleted the parts I think are irrelevant in this class (such as the code that displays a message string on screen etc).
ALSO NOTE: I implement here IComparable<Slot>
but I also tried it with IComparable<UIController>
. (like I say, I've seen lots of examples here and other websites, but cannot quite get it to work in my code.)
Why not use delegate form?
Array.Sort(slots, (slot1, slot2) => slot1.name.CompareTo(slot2.name));
If you still want to implement the IComparable interface, you must write it inside the Slot class.
And you can also implement IComparer interface in any class.
class AnyClass : IComparer<Slot>
{
public int Compare(Slot slot1, Slot slot2)
{
return slot1.name.CompareTo(slot2.name);
}
}
I was able to keep the code within my UIController class which is how I imagined it would be (since I built the array of slots there , it felt right for me to sort it there also.)
Here's how its done:
public class UIController : MonoBehaviour, IComparer<Slot>
{
public static UIController instance;
public Text uiMessageBox;
public Slot[] slots;
private void Awake()
{
slots = FindObjectsOfType<Slot>();
Array.Sort(slots, this); // i just passed 'this' as the IComparer parameter :)
}
public int Compare(Slot x, Slot y)
{
return x.name.CompareTo(y.name);
}
}
