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

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.

 

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEngine.UI;
5.  
6. public class DialogueManager : MonoBehaviour
7.  
8.  
9. {
10.     public Text nameText;
11.     public Text dialogueText;
12.     public Animator animator;
13.  
14.     private Queue<string> sentences;
15.  
16.  
17.     // Start is called before the first frame update
18.     void Start()
19.     {
20.         sentences = new Queue<string>();
21.     }
22.  
23.     public void StartDialogue (Dialogue dialogue)
24.     {
25.  
26.         animator.SetBool("isOpen", true);
27.  
28.         nameText.text = dialogue.name;
29.  
30.         sentences.Clear();
31.  
32.         foreach (string sentence in dialogue.sentences)
33.  
34.         {
35.             sentences.Enqueue(sentence);
36.  
37.         }
38.  
39.         DisplayNextSentence();
40.  
41.     }
42.  
43.     public void DisplayNextSentence ()
44.     {
45.         if (sentences.Count == 0)
46.         {
47.             EndDialogue();
48.             return;
49.         }
50.  
51.         string sentence = sentences.Dequeue();
52.         StopAllCoroutines();
53.         StartCoroutine(TypeSentence(sentence));
54.     }
55.  
56.     IEnumerator TypeSentence (string sentence)
57.     {
58.         dialogueText.text = "";
59.         foreach (char letter in sentence.ToCharArray())
60.         {
61.             dialogueText.text += letter;
62.             yield return null;
63.         }
64.     }
65.  
66.  
67.         void EndDialogue()
68.         {
69.         animator.SetBool("isOpen", false);
70.     }

42.     }
43.    
44.     void OnHealthChanged(int maxHealth, int currentHealth)
45.         {
46.         if (ui != null)
47.         {
48.             ui.gameObject.SetActive(true);
49.             lastMadeVisibleTime = Time.time;
50.        
51.             float healthPercent = currentHealth / (float)maxHealth;
52.             healthSlider.fillAmount = healthPercent;
53.          
54.             if (currentHealth <= 0)
55.             {
56.                 Destroy(ui.gameObject);
57.             }
58.         }
59.  
60.         }
61.  

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
