Screen space overlay for Dialogue stops Screenspace Overlay for HP bar from appearing.

Unity Engine
1

Hi all,

I will apologise for the lack of detail right now ( I will add code and more detail when I get home from work).

I am building an rpg, I have built a hp system and a dialogue system out of two separate screen space overlays, the hp system came first, but when i add the dialogue system it stops the hp bars (which follow the characters around) from appearing at all now. can these two overlays exist at the same time? I am new and have been relying heavily on guides found on popular video upload sites.

I will add code when I’m home, I just wanted to get the question out there while its clear in my mind.

thanks to all who read and especially all who would help.

                ui.gameObject.SetActive(false);
                break;
            }
        }

        GetComponent<CharacterStats>().OnHealthChanged += OnHealthChanged;
    }
   
    void OnHealthChanged(int maxHealth, int currentHealth)
        {
        if (ui != null)
        {
            ui.gameObject.SetActive(true);
            lastMadeVisibleTime = Time.time;
        
            float healthPercent = currentHealth / (float)maxHealth;
            healthSlider.fillAmount = healthPercent;
         
            if (currentHealth <= 0)
            {
                Destroy(ui.gameObject);
            }
        }

        }

the dialogue system runs on 3 separate scripts. I dont know why adding dialogue system broke health ui system. could anyone help me please?

I’ve managed to fix this. seems that having 2 or 3 days away from the project allowed me to see clearly :slight_smile:
