PlayerController.Instance.onHealthChangedCallback += UpdateHeartsHUD;
InstantiateHeartContainers();
UpdateHeartsHUD();
}
// Update is called once per frame
void Update()
{
}
void SetHeartContainers()
{
for(int i = 0; i < heartContainers.Length; i++)

else

}
}
}
void SetFilledHearts()

{
GameObject temp = Instantiate(heartContainerPrefab);

heartContainers[i] = temp;
heartFills[i] = temp.transform.Find(“HeartFill”).GetComponent<Image>();
}
}
void UpdateHeartsHUD()
