Help with ImageRandomizer script

Scripting
1

Hello,
I’m a novice coder. Teaching myself some AR using this Unity tutorial.
I’ve tried compiling the script but I’m confused. can anyone help please?

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

public class ImageRandomizer : MonoBehaviour
public SpriteRenderer randomSpriteRenderer; //The sprite renderer that will display the random image
public Sprite[] randomSprites;              //An Array of sprites that will be used for the image randomization

public float timeBetweenChange = 0.2f;      //The amount of time between switching the image
public float timeUntilStopping = 3.0f;      //The total amount of time until randomization stops
private int RandomImageIndex = 0;           //Keep track of which image we're currently displaying
private float ImageChangeTimer;             //How much time is left until we switch to new image

{
    // Start is called before the first frame update
    void Start()
    {
      // Set this timer variable as soon as the script starts so it's ready for the update function
        ImageChangeTimer = timeBetweenChange; 
    }
   
    // Update is called once per frame
    void Update()
    {
      // Remove delta time from both active timers. This subtracts a small amount of time from the
// overall time we described in "timeBetweenChange" and "timeUntilStopping"
        ImageChangeTimer -= Time.deltaTime;
        timeUntilStopping -= Time.deltaTime;

// If we've fully run out of time we need to select a final random image
if(timeUntilStopping <= 0.0f)
        {
// The final image will be selected at random
            randomSpriteRenderer.sprite = randomSprites[Random.Range(0, randomSprites.Length)];

// Destroy this script immediately stopping it from running anymore in the future
            DestroyImmediate(this);

// Return so no other code runs in this Update function call
return;
        }

// If RandomizationTimer is less than or equal to zero it's time for a new image
if(ImageChangeTimer <= 0.0f)
        {
// To ensure we see all the images we increase the RandomImageIndex to see the next
// image in the array
            RandomImageIndex++;

// If our index has gone past the end of the array, reset it to zero so the cycle
// can start again
if(RandomImageIndex >= randomSprites.Length)
            {
                RandomImageIndex = 0;
            }

//Assign the new sprite to the sprite renderer
            randomSpriteRenderer.sprite = randomSprites[RandomImageIndex];

//Reset the "RandomizationTimer" to start counting down again
            ImageChangeTimer = timeBetweenChange;  
    }
}

The opening brace for your class declaration is after all your member variables. Move the first { to directly after MonoBehaviour.
