如何制作重新启动按钮或使用 r 重新启动场景

Question

See when my player dies you can restart well that's what I wanted but I can't get it to work and I want it to where you have an option of either pressing r or the button to restart.

Can I please get a couple of tips for this probably some code too but that's up to you btw I am a beginner and need much help my game is just a basic learning game and I will love help from you fellow gamedevs

This is my old code

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class ResetManager : MonoBehaviour
{
    public static ResetManager Instance { get; private set; }

    public event System.Action ResetEvent = new delegate {};

    public void Awake()
    {
        Instance = this;
    }

    public static void ResetScene()
    {
        Instance.ResetEvent();
    }
}

I would like to know if I could make it without scene manager

Welcome to stack overflow, here I will show a brief tutorial on how to build the key in the UI as well as execute the reset code. To create a UI button , go to Hierarchy and right-click, you can create a Button from the UI menu as shown below.

After creating the button, attach the script to a Manager object, click the button and reference the reset command at the bottom of the event, as below, keeping in mind that the unity event does not support static method's.

public void ResetScene() => SceneManager.LoadScene(SceneManager.GetActiveScene().name);

After performing the above steps, your button will restart the scene when clicked.

You can also restart the scene when you press the R key by adding the following code.

private void Update()
{
    if (Input.GetKeyDown(KeyCode.R)) ResetScene();
}
