OnComplete on Reversed loop

[EricBatlle]

I'm trying to achieve this:

using DG.Tweening;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;

public class Menu : MonoBehaviour
{
	[SerializeField] private List<GameObject> menuButtons = new List<GameObject>();

	[SerializeField] protected float duration = 0.35f;
	[SerializeField] protected Ease easeIn = Ease.OutBack;
	[SerializeField] protected Ease easeOut = Ease.InBack;

	private Sequence menuTween = null;

	private void Awake()
	{
		menuTween = DOTween.Sequence();
		foreach (var buttonGO in menuButtons)
		{
			buttonGO.GetComponent<Button>().onClick.AddListener(Close);
		}
	}

	private void Close()
	{
		if (menuTween.IsActive() && menuTween.IsPlaying())
			return;

		menuTween = DOTween.Sequence();
		
		foreach (var button in menuButtons)
		{
			menuTween.Append(button.transform.DOScale(Vector3.zero, duration).SetEase(easeOut).OnComplete(() => button.SetActive(false)));
		}
		menuTween.OnComplete(() => isOpen = false);
	}
}

But on reverse, there are two ways to achieve this, first one I can reverse the list on the foreach, or second one, use a for loop on the reverse order, something like:

for (int i = menuButtons.Count - 1; i > 0; i--)
{
	menuTween.Append(menuButtons[i].transform.DOScale(Vector3.zero, duration).SetEase(easeOut).onComplete(() => menuButtons[i].SetActive(false)));
}

But if I use this second method it always affect the menuButtons[0], so every time the lambda method is called, the i value seems 0, what is happening?

i is sent the reference not a value to the inner looping function. so at the end, it will be 0 in you case
