Question Using Tracked Image Manager to make a button interactable

Hey!

What I am basically trying to do is create a menu where I can select prefabs and place them on a plane, and I do have this working, but I want to make them unlock-able. So what I want is to be able to scan an image using the Image Tracker and then have it make a specific button interact-able.

What I have so far is a working tracker, where it finds the correct object that corresponds with the right image. Is there a way I can change this to instead spawn the prefab but just make a specific button interact-able?

This is what I have (sorry, I am new to this and not sure on the forum etiquette)

Code (CSharp):

1.  
2. using System.Collections;
3. using System.Collections.Generic;
4. using UnityEngine;
5. using UnityEngine.XR.ARFoundation;
6. using UnityEngine.XR;
7.  
8.  
9. [RequireComponent(typeof(ARTrackedImageManager))]
10. public class ImageTracking : MonoBehaviour
11. {
12.  
13.     [SerializeField]
14.     private GameObject[] placeablePrefabs;
15.  
16.     private Dictionary<string, GameObject> spawnedPrefabs = new Dictionary<string, GameObject>();
17.     private ARTrackedImageManager trackedImageManager;
18.  
19.     private void Awake()
20.     {
21.         trackedImageManager = FindObjectOfType<ARTrackedImageManager>();
22.  
23.         foreach (GameObject prefab in placeablePrefabs)
24.         {
25.             GameObject newPrefab = Instantiate(prefab, Vector3.zero, Quaternion.identity);
26.             newPrefab.name = prefab.name;
27.             spawnedPrefabs.Add(prefab.name, newPrefab);
28.         }
29.     }
30.  
31.     private void OnEnable()
32.     {
33.         trackedImageManager.trackedImagesChanged += ImageChanged;
34.     }
35.     private void OnDisable()
36.     {
37.         trackedImageManager.trackedImagesChanged -= ImageChanged;
38.     }
39.  
40.     private void ImageChanged(ARTrackedImagesChangedEventArgs eventArgs)
41.     {
42.         foreach (ARTrackedImage trackedImage in eventArgs.added)
43.         {
44.             UpdateImage(trackedImage);
45.         }
46.         foreach (ARTrackedImage trackedImage in eventArgs.updated)
47.         {
48.             UpdateImage(trackedImage);
49.         }
50.         foreach (ARTrackedImage trackedImage in eventArgs.removed)
51.         {
52.             spawnedPrefabs[trackedImage.name].SetActive(false);
53.         }
54.     }
55.  
56.     private void UpdateImage(ARTrackedImage trackedImage)
57.     {
58.         string name = trackedImage.referenceImage.name;
59.         Vector3 position = trackedImage.transform.position;
60.  
61.         GameObject prefab = spawnedPrefabs[name];
62.         prefab.transform.position = position;
63.         prefab.SetActive(true);
64.  
65.         foreach (GameObject go in spawnedPrefabs.Values)
66.         {
67.             if (go.name != name || trackedImage.trackingState == UnityEngine.XR.ARSubsystems.TrackingState.None || trackedImage.trackingState == UnityEngine.XR.ARSubsystems.TrackingState.Limited)
68.             {
69.                 go.SetActive(false);
70.             }
71.         }
72.     }
73.  
74. }
75.  
76.  
77.

A bit of a backstory: I am a student animator, and have been hired by the uni to create an AR experience for new students on a campus orientation trail. They gave me full creative freedom so I have chosen to create an app in Unity. (They suggested Aero but that was not all that great for what I wanted to do, it was too unreliable for sharing). So I am new to this, but I really want to learn more code, and this has been very fun! If you can help me with this, that would be brilliant!

Thank you!
