Hey! So I was following this tutorial and i came accross an error. can anyone help? Thanks in advance
Here is my code:

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

public class PlayerVitals : MonoBehaviour
{
	public Slider healthSlider;
	public int maxHealth;
	public int healthFallRate;

	public Slider thirstSlider;
	public int maxThirst;
	public int thirstFallRate;

	public Slider hungerSlider;
	public int maxHunger;
	public int hungerFallRate;

	void Start()
	{
		healthSlider.maxValue = maxHealth;
		healthSlider.value = maxHealth;

		thirstSlider.maxValue = maxThirst;
		thirstSlider.value = maxThirst;

		hungerSlider.maxValue = maxHunger;
		hungerSlider.value = maxHunger;
	}

	void Update()
	{
		if (hungerSlider.value <= 0 && (thirstSlider <= 0))
		{
			healthSlider.value -= Time.deltaTime / healthFallRate = 2;
		}

		else if(hungerSlider.value <= 0 || thirstSlider.value <= 0)
		{
			
			healthSlider.value <= Time.deltaTime / healthFallRate;
		}

		if(healthSlider.value <= 0)
		{
			CharacterDeath;
		}

		if(hungerSlider.value >= 0)
		{
			hungerSlider.value -= Time.deltaTime / hungerFallRate;
		}
		else if(hungerSlider.value -= 0)
		{
			hungerSlider.value = 0;
		}

		else if(hungerSlider.value >= maxHunger)
		{
			hungerSlider.value = maxHunger;
		}

		if(thirstSlider.value >= 0)
		{
			thirstSlider.value -= Time.deltaTime / thirstFallRate;
		}
		else if(thirstSlider.value -= 0)
		{
			thirstSlider.value = 0;
		}

It should tell you on which line that has the error…trying to find it through the whole script will be hard

Your syntax is all kinds of messed up.

healthSlider.value -= Time.deltaTime / healthFallRate = 2;

The assignment ( = 2) makes no sense here, try removing it:

healthSlider.value -= Time.deltaTime / healthFallRate;

Throughout this script, your testing if values are larger or smaller, than this line comes up, which makes no sense:

else if(hungerSlider.value -= 0)

Change it to:

else if(hungerSlider.value <= 0)

I would suggest going over the tutorial again more carefully and checking your syntax. “-=” and “<=” are 2 completely different things.
