how to change the player material by clicking the prefab?

Firstly,i use to this script to create ScriptableObject--ShopItem

Code (CSharp):

1.  
2. [CreateAssetMenu(menuName = "Shop/Shop Item")]
3. public class ShopItem : ScriptableObject
4. {
5.     public string itemName;
6.  
7.  
8.     public Material material;
9.     public Mesh mesh;
10.     public Sprite image;
11.     public Button m;
12. }

after that,i use this script to create a skin shop list and create 6 sphere with 6 different materials

Code (CSharp):

1. public void Start()
2.     {
3.         ABCShop();
4.    
5.     }
6.     public void ABCShop()
7.     {
8.         for (int i = 0; i < shopItem.Length; i++)
9.         {
10.             ShopItem si = shopItem[i];
11.             GameObject itemObject = Instantiate(shopItemPrefab, shopContainer);
12.        
13.             itemObject.GetComponent<Button>().onClick.AddListener(() => OnButtonClick(si));
14.          
15.             itemObject.GetComponent<Renderer>().material = si.material;
16.             itemObject.GetComponent<MeshFilter>().sharedMesh = si.mesh;
17.          
18.         }
19.     }
20.  
21.   public void OnButtonClick(ShopItem item)
22.     {
23.      
24.  
25.     }
26.  

now,I create 6 sphere with 6 different materials
what should i write in OnButtonClick function to change the material of my player?
For example,
when Sphere A have material A,when i click on Sphere A,the material of my player will change to material A
when Sphere B have material B,when i click on Sphere B,the material of my player will change to material B
i wrote this script,but not working

Code (CSharp):

1.    public void OnButtonClick(ShopItem item)
2.     {
3.      
4.         GetComponent<Renderer>().material = M.Newskin;
5.        Debug.Log(item.name);
6.     }

 

Looking over your scripts, I would guess you need a link the player doing the clicking.

Code (CSharp):

1. void Update()
2.     {
3.         if (Input.GetMouseButtonDown(0))
4.         {
5.             Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
6.             RaycastHit hit;
7.             if (Physics.Raycast(ray, out hit))
8.             {
9.                 hit.collider.GetComponent<Renderer>().material = M.Newskin;
10.                 // or hit.collider.GetComponent<Renderer>().material = GetComponent<Material>();
11.             }
12.         }
13.     }

 

Can i just write in this?pr is assigned to shopitem, player is assigned to player

i put the script in unity inspectror's button and call change(),why it doesnt work?

Code (CSharp):

1. using UnityEngine;
2. using UnityEngine.UI;
3. using UnityEngine.Events;
4. using UnityEngine.EventSystems;
5.  
6. public class SwitchSkin : MonoBehaviour
7. {
8.     public GameObject Player;
9.     public GameObject pr;
10.  
11.     void Update()
12.     {
13.        
14.     }
15.  
16.     public void Change()
17.     {
18.    
19.             pr.GetComponent<Renderer>().material = Player.transform.GetChild(3).GetComponent<Material>();
20.             // or hit.collider.GetComponent<Renderer>().material = GetComponent<Material>();
21.        
22.     }

 

Firstly if you are changing the player you might want to flip your code.

Code (CSharp):

1. Player.transform.GetChild(3).GetComponent<Material>()=pr.GetComponent<Renderer>().material;

Secondly, It is hard to figure out how the entire system works, but maybe the renderer is further down and you could try

Code (CSharp):

1. pr.GetComponentInChildren<Renderer>().material

Try to Debug.Log(material.name), for the pr and the same for the player. The name should tell you if you have the right object, sometimes it is pointing to null.
