I am busy creating a health system and created a game over screen to show when current health is 0/player is dead. But the game over screen is not showing (I don't know much about if)

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.SceneManagement;
using UnityEngine.InputSystem;

public class HealthSystem : MonoBehaviour
{
    public int maxHealth = 100;
    public int currentHealth;

    public HealthBar healthBar;
    public GameObject gameOver;

    public bool damage;

    // Start is called before the first frame update
    void Start()
    {
        currentHealth = maxHealth;
        healthBar.SetMaxHealth(maxHealth);
    }

    void TakeDamage(int damage)
    {
        currentHealth -= damage;

        healthBar.SetHealth(currentHealth);
    }
    
    public void GameOver()
    {
        if (currentHealth == 0)
        {
            gameOver.SetActive(true);
        }
    }

    public void RestartButton()
    {
        SceneManager.LoadScene("Playground");
    }
    
    public void OnDamage(InputValue value)
    {
        DamageInput(value.isPressed);
        TakeDamage(10);
    }

    public void DamageInput(bool newDamageState)
    {
        damage = newDamageState;
    }
}

CodePudding user response：

You are nowhere calling GameOver() in your code. Every time you decrement currentHealth(), check if it reached zero and do the necessary. For this, call GameOver() in your TakeDamage() method

void TakeDamage(int damage)
{
    currentHealth -= damage;
    
    GameOver();

    healthBar.SetHealth(currentHealth);
}

Also, check if currentHealth is less than or equal to 0, not just 0

public void GameOver()
{
    if (currentHealth <= 0)
    {
        gameOver.SetActive(true);
    }
}
