I’m making a health bar, from the Brackey’s tutorial, I’ve tried lerp a million different ways and nothing, it moves at fractions, speed doesn’t change anything and I’m stumped, would appreciate some help:

using UnityEngine.UI;
  
public class HealthBar : MonoBehaviour
{
    public Slider healthSlider;
  
    public void SetMaxHealth(float health)
    {
        healthSlider.maxValue = health;
        healthSlider.value = health;
    }
  
    public void SetHealth(float health)
    {
        healthSlider.value = health;
    }
}

Well, you haven’t implemented any kind of a lerping function in there at all and you will likely want that to happen in the SetHealth function.

private float targetHealth;
private float timeScale = 0;
private bool lerpingHealth = false;
  
public void SetHealth( float health )
{
    targetHealth = health;
    timeScale = 0;
    
    if(!lerpingHealth)
        StartCoroutine(LerpHealth());
}
  
private IEnumerator LerpHealth( )
{
    float speed = 2;
    float startHealth = healthSlider.value;
  
    lerpingHealth = true;
  
    while(timeScale < 1)
    {
        timeScale += Time.deltaTime * speed;
        healthSlider.value = Mathf.Lerp(startHealth, targetHealth, timeScale);
    }
    lerpingHealth = false;
}

if anybody has still issues, it’s probably because there’s no yield return null in the coroutine IEnumerator method.
This way, it’s updated every frame. probably obvious, but just to be safe
