Pushing a GameObject Button on Mobile (Help)

Hi all, trying to make an AR app where I click on a button represented by a gameobject and then the button changes the visibility of a separate gameobject. It should cast a raycast from where was touched to the object and then if it hits a button; cycle it between three states which change the buttons colour and the object associated with its visibility.

I feel like I'm close but when I press the button nothing happens, no sound, no colour change no animation.

Can anyone take a look at my code and give me a pointer? Think I might be trying to change the color incorrectly.

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEngine.EventSystems;
5.  
6. public class ButtonPress : MonoBehaviour
7. {
8.     //State
9.     public int ButtonState;
10.  
11.     //Sounds
12.     public AudioClip ButtonClickNoise;
13.  
14.     //Animations
15.     public Animation ButtonPressAnimation;
16.  
17.     //GameObjects and Materials
18.     public GameObject ButtonCollider;
19.     public GameObject MACEPart;
20.     public GameObject ButtonPart;
21.     public Material PartMaterial;
22.     public Material ButtonMaterial;
23.  
24.     //Raycast Stuff
25.     public GameObject RaycastReturn;
26.  
27.     //Line Renderer
28.     private LineRenderer LineLink;
29.  
30.     void Start()
31.     {
32.         Debug.Log("Button Start Was Called.");
33.  
34.         ButtonState = 0;
35.         PartMaterial = MACEPart.GetComponent<MeshRenderer>().material;
36.         ButtonPart.GetComponent<MeshRenderer>().material.color = Color.green;
37.         LineLink = ButtonPart.GetComponent<LineRenderer>();
38.         ButtonPressAnimation = ButtonPart.GetComponent<Animation>();
39.  
40.         //Draw line between objects
41.         LineLink.SetPosition(0, ButtonPart.transform.position);
42.         LineLink.SetPosition(1, MACEPart.transform.position);
43.         LineLink.enabled = true;
44.     }
45.  
46.     // Update is called once per frame
47.     void Update()
48.     {
49.         if (Input.touchCount > 0 && Input.touches[0].phase == TouchPhase.Began)
50.         {
51.             //Raycast Hit Detection
52.             Ray ray = Camera.main.ScreenPointToRay(Input.GetTouch(0).position);
53.             RaycastHit hit;
54.             if (Physics.Raycast(ray, out hit))
55.             {
56.                 if (hit.collider != null)
57.                 {
58.                     if (ButtonCollider = hit.collider.gameObject) //if the raycast has hit the button
59.                     {
60.                         Debug.Log(this.gameObject.name + " Was Clicked."); //to check if actually working. remove if it is
61.  
62.                         ButtonPressAnimation.Play();
63.                         AudioSource.PlayClipAtPoint(ButtonClickNoise, gameObject.transform.localPosition);
64.  
65.                         switch (ButtonState) //Do something based on the Buttons State
66.                         {
67.                             case 0: //Visible component
68.  
69.                                 MACEPart.SetActive(true);
70.                                 Color Visible = PartMaterial.color;
71.                                 Visible.a = 1.0f;
72.                                 PartMaterial.SetColor("Visible", Visible);
73.  
74.                                 ButtonMaterial.SetColor("Green", Color.green);
75.  
76.                                 ButtonState = 1;
77.                                 break;
78.  
79.                             case 1: //Semi-Transparent
80.                                 MACEPart.SetActive(true);
81.                                 Color SemiTransparent = PartMaterial.color;
82.                                 SemiTransparent.a = 0.3f;
83.                                 PartMaterial.SetColor("Semi-Transparent", SemiTransparent);
84.  
85.                                 ButtonMaterial.SetColor("Amber", Color.yellow);
86.  
87.                                 ButtonState = 2;
88.                                 break;
89.  
90.                             case 2: //Semi-Transparent
91.                                 MACEPart.SetActive(false);
92.  
93.                                 ButtonMaterial.SetColor("Red", Color.red);
94.  
95.                                 ButtonState = 0;
96.                                 break;
97.  
98.                             default:
99.                                 Debug.Log("Button is not in one of the three states!");
100.  
101.                                 break;
102.                         }
103.                     }
104.                 }
105.             }
106.         }
107.     }
108. }

 

Anyone able to help with this?
