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.

inside on click/function/my script, is not show me the restart option

Very cool thank you!

TSM!!!! IT WORKED!!! my dad just bought apple dev account for me and now i can publish my first game!!!!

Brother I have spended the last day and a half triying to do this by reverse ingeniering the code I had. Thanks! this was kick and simple.

ty

please make some tutorial how to make restart button after for example one scene was locked because player has finished the game

How do you reset multiple scenes, for example if I die on the 3rd level and press go back to menu then select the the 1st level in menu, everything in game doesn't work, how do I do a complete restart of the game where each level resets

Thank you alot! :D

Thanks from brazil S2

How can I write codes in my restart button in C# platform game ?

Can you make a video of how to handle static variables upon a restart. It appears that when the scene reloads, the static variables still have their old values.

thank you it worked for me is amazing new sub!.

nice and clear! thank you

This only works if your game only has one level. If you have multiple levels, the restart button will always spawn you into the level written in the script.
To make a true restart button that loads the current scene, use this code:
SceneManager.LoadScene(SceneManager.GetActiveScene().name);

Please help my code is :using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.SceneManagement;
public class RewindTime : MonoBehaviour
{
public void RestartGame()
{
SceneManager.LoadScene("Level1");

}
}
" And i get a complier error type namespace defenition or end of file as expected

I can't find the function. Any help?

This is so cool

THANKS!! So easy

Why does my scene freeze after restarting?

Edit: nvm I forgot to put Time.timeScale = 1f;

Script

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

You can probably set the scene that you want to reload as
SceneManager.LoadScene(SceneManager.GetActiveScene())

thank you needed this for my game

y is this not working for meeeeeeeee

Спасибо большое за видео! Вы мой спаситель, Александр)
Подскажите, у Вас есть видео, в котором бы объяснялось, как научить эту кнопку появляться только после смерти гг?

I don't know why it doesn't grab the click or the touch of the reset button. I did everything that appeared in the procedure. I even checked that the scene was the same as the code. Help!

Perfect!! Fast and simple like every Unity tutorial should be.

Thanks for the tutorial! @Alex, I've got a question. I added a restart button to my simple puzzle game with WinText (see your another guide), and it happens that WinText stays on a screen when I press restart button. How I can avoid it and make full restart?
