✅ Object reference error? Using Unity
I'm trying to create a slider system to visualize various status bars using references instead of directly setting values in each bar. I can't seem to wrap my head around why this is throwing an 'Object reference not set to an instance of an object' issue.
My statblock is here:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class FinkratStatblock : MonoBehaviour
{
public float MaxHealth = 100;
public float CurrentHealth = 100;
public float MaxEnergy = 200;
public float CurrentEnergy = 200;
public float MoveSpeed = 7.0f;
public float MaxHunger = 100;
public float CurrentHunger = 0;
public float MaxThirst = 100;
public float CurrentThirst = 0;
public float MaxSleepy = 500;
public float CurrentSleepy = 0;
public float MaxCatalystOil = 200;
public float CurrentCatalystOil = 200;
public float AfraidAmount = 0;
}
and the healthbar script I'm trying to work on is here. It's saying the error line is line 20, aka the first get component CurrentHealth:
using UnityEngine;
using UnityEngine.UI;
public class Healthbar : MonoBehaviour
{
public FinkratStatblock finkratStatblock;
public float currentHealth;
public float maxHealth;
public Slider slider;
public Image fillImage;
private void Awake()
{
slider = GetComponent<Slider>();
currentHealth = GetComponent<FinkratStatblock>().CurrentHealth;
maxHealth = GetComponent<FinkratStatblock>().MaxHealth;
}
// Start is called before the first frame update
void Start()
{
slider.maxValue = maxHealth;
slider.minValue = 0;
currentHealth = maxHealth;
}
void TakeDamage(float amount)
{
currentHealth -= amount;
}
// Update is called once per frame
void Update()
{
slider.value = currentHealth / maxHealth;
}
