How to make a gameobject share the material of the collider it collides with?

Hi,

I am looking to have the material of a game object changed to the material of the object that collides with it. I haven’t scripted much before but am starting with this:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class ChangeMaterial : MonoBehaviour {
public Material material;
public Renderer rend;
// Use this for initialization
void Start ()
{
rend = GetComponent();
rend.enabled = true;
rend.sharedMaterial = material[0];
}

void OnCollisonEnter (Collision col) 
{
	if (col.gameObject.tag == "Box")
	{
		rend.sharedMaterial = material[1];
	}
	else
	{
		rend.sharedMaterial = material [2];
	};
}

}

Does the shared material call mean that the material will be change to the one of the collider or one which has been assigned to it in the inspector?
This script isn’t working, and was wondering what the issue might be.

Thanks.

You should change the array materials of the Renderer, instead of sharedMaterial.

If you do a little reading in the docs on Unity it will lead you in the right direction. I absolutely recommend following YouTube tutorials and the Unity tutorials when moving on further in development because if you continue to run in to problems now then wen it gets complicated you won’t be able to do anything.

using System.Collections; 
using System.Collections.Generic; 
using UnityEngine;
public class ChangeMaterial : MonoBehaviour { 
public Renderer rend; 
 // Use this for initialization
 void Start ()
 { 
    rend = GetComponent<Renderer>(); 
    rend.enabled = true;
 }
 void OnCollisonEnter (Collision col) 
 {
     if (col.gameObject.GetComponent<Renderer>() != null)
     {
         rend.material = col.gameObject.GetComponent<Renderer>().material;
     }
 }

}
