How to make a button appear with a condition?

Questions & Answers

Hi, I am currently trying to create a restart button for my game. It should appear when the time is up but somehow the button’s not appearing when the time’s duration is up.

using UnityEngine;
using System.Collections;
using UnityEngine.SceneManagement;
using UnityEngine.UI;

public class Restart : MonoBehaviour
{
	public GameObject button;
	public int timeLeft = 60;

	// Use this for initialization
	void Start()
	{
		button.SetActive (false);
	}


	// Update is called once per frame
	void Update()
	{
		if (timeLeft <= 0)
		{
			button.SetActive (true);
			StopCoroutine("LoseTime");
		}
	}

	public void RestartGame() 
	{
		SceneManager.LoadScene(SceneManager.GetActiveScene().name); // loads current scene
	}
		

	IEnumerator LoseTime()
	{
		while (true)
		{
			yield return new WaitForSeconds(1);
			timeLeft--;
		}
	}

}

It does not appear like you are starting the LoseTime Coroutine anywhere. You should call StartCoroutine in the Start() function.
