Question OnTriggerEnter/Exit Collider2d Dialogbox problem

Hey Everyone im new to C# and Unity game devoloping. İm trying to make a simple Dialogue system. When i enter Collider2D is set trigger Dialogue appears, when i Exit Dialogue disapper. İ do somewhat close to this. But not work as neded. When i enter collider Dialog box continously activated and disactivated even if i dont exit the collider. Can Someone tweak code a bit ? And Add V2 as a Destroy game object line on exit proper way ? For on the exit disabiling the box. İ cant manage the do that in working way.Here's the code lines;

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEngine.UI;
5. using TMPro;
6.  
7. public class DialogueSysteam : MonoBehaviour {
8.  
9.     public GameObject dialogBox;
10.     public TMP_Text dialogText;
11.     public string dialog;
12.     public bool playerInRange;
13.  
14.     // Start is called before the first frame update
15.     void Start()
16.     {
17.      
18.     }
19.  
20.     // Update is called once per frame
21.     void Update()
22.     {
23.         if(playerInRange)
24.         {
25.  
26.      
27.              if(dialogBox.activeInHierarchy){
28.               dialogBox.SetActive(false);
29.              } else{
30.               dialogBox.SetActive(true);
31.               dialogText.text = dialog;
32.              }
33.         }
34.     }
35.     private void OnTriggerEnter2D(Collider2D other)
36.     {
37.         if (other.CompareTag("Player"))
38.         {
39.             playerInRange = true;
40.         }
41.     }
42.  
43.     private void OnTriggerExit2D(Collider2D other)
44.     {
45.         if (other.CompareTag("Player"))
46.         {
47.             playerInRange = false;
48.             dialogBox.SetActive(false);
49.         }
50.     }
51. }
52.  

İ guess İf state broke the code ? But im not sure.

 

Make it more simple like this:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class DialogueSystem : MonoBehaviour
6. {
7.     public GameObject dialogBox;
8.     public TMP_Text dialogText;
9.     public string dialog;
10.     public bool playerInRange = false;
11.  
12.     void Start()
13.     {
14.         dialogBox.SetActive(playerInRange);
15.         dialogText.text = dialog;
16.     }
17.  
18.     private void OnTriggerEnter2D(Collider2D other)
19.     {
20.         if (other.CompareTag("Player"))
21.         {
22.             playerInRange = true;
23.             dialogBox.SetActive(playerInRange);
24.         }
25.     }
26.  
27.     private void OnTriggerExit2D(Collider2D other)
28.     {
29.         if (other.CompareTag("Player"))
30.         {
31.             playerInRange = false;
32.             dialogBox.SetActive(playerInRange);
33.         }
34.     }
35. }
36.  

 

Thanks for your help and clearing up the code.
