Unity Tutorial How To Make Restart Button To Reload The Scene In Jetpack Clone Android Game

ALARM! ALARM! COROUTINE ISSUE DETECTED!
If you press and hold your finger at the very beginning of the game, pass through the comets without touching them, pick up the fuel can and fly off the screen without releasing your finger then fuel counter will freeze at some value and will not go down until you release and put finger back on the screen. It happens because of the coroutine. When it starts it takes the current fuel amount value (let it be 50 for example). Coroutine stops with two conditions – if finger is released or if fuel amount inside this coroutine is equal to zero. So if you pick up fuel can while coroutine is running when fuel amount equals to 50 then overall fuel amount becomes 100 back again. But inside the coroutine, it still goes down from 50. When coroutine is over (loop comes to zero) then engine should stop but it doesn't happen because fuel amount is 50 now. And it will always be 50 until you release the finger and put it back on the screen to start new coroutine which will countdown from 50 to 0.
So to fix this issue we should replace this line in BurnFuel coroutine
for (int i = fuelAmount; i >= 1; i–)
with this line
while (fuelAmount > 0)
and everything will work fine.
So coroutine code will look like this

private IEnumerator BurnFuel()
{
while (fuelAmount > 0)
{
fuelAmount -= 1;
yield return new WaitForSeconds(0.01f);

if (Input.touchCount > 0 && Input.GetTouch(0).phase == TouchPhase.Ended)
//if (Input.GetMouseButtonUp(0))
break;
}
}

But we should use WHILE loop inside any of the coroutine very very carefully because it can halt the running project easily.

Script

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.SceneManagement;
public class Restart : MonoBehaviour {
public void RestartGame()
{
SceneManager.LoadScene ("Scene Name);
}
}
