Resolved Help with trigger and canvas

Hey guys, I'm trying to do a code that trigger an object and calls a specific Canvas, like an interaction pressing space and showing a Canvas with a "Do you want to sleep (when close to a bed)? Yes or No (can be a button)".

I did something similar just being on the trigger and it automatecally opens the canvas, but it's not the best solution, an interaction would be so much better for my project.

I lost all my night on it, and still no results... since I'm a designer and not a programmer, it's so hard for me to understand it. Could someone help me? I tried a lot of codes and the last one is that one:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEngine.SceneManagement;
5.  
6. public class TriggerDialogue : MonoBehaviour
7. {
8.     public GameObject scene;
9.  
10.     void OnTriggerEnter2D(Collider2D other)
11.     {
12.         if (Input.GetKeyDown(KeyCode.Z) && other.CompareTag("Player"))
13.         {
14.             scene.SetActive(true);
15.         }
16.     }
17.  
18.     void OnTriggerExit2D(Collider2D other)
19.     {
20.         if (other.CompareTag("Player"))
21.         {
22.             scene.SetActive(false);
23.         }
24.     }
25. }

Thank you in advance.

 

You need to listen for the key press in update, so use your trigger to set a bool to let update know it can listen for the key press.

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEngine.SceneManagement;
5.  
6. public class TriggerDialogue : MonoBehaviour {
7.  
8.     public GameObject scene;
9.     bool playerIsInTriggerArea = false;
10.     bool uiActive = false;
11.  
12.     void Update () {
13.  
14.         if (playerIsInTriggerArea && !uiActive) {
15.             if (Input.GetKeyDown ("space")) {
16.                 uiActive = true;
17.                 scene.SetActive (true);
18.             }
19.         }
20.  
21.     }
22.  
23.     void OnTriggerEnter2D (Collider2D other) {
24.  
25.         if (other.CompareTag ("Player")) {
26.             playerIsInTriggerArea = true;
27.         }
28.  
29.     }
30.  
31.     void OnTriggerExit2D (Collider2D other) {
32.  
33.         if (other.CompareTag ("Player")) {
34.             playerIsInTriggerArea = false;
35.         }
36.  
37.     }
38.  
39. }

 

Thank you, worked perfecly fine! And it's good to learn it. Have a great day.
