Hi im trying to make a object become outlined after it is clicked, but im having trouble getting the materals array in the mesh renderer, code attached below, thanks.

using System.Collections;
using System.Collections.Generic;
using UnityEditor.SearchService;
using UnityEngine;
using UnityEngine.UI;
using UnityEngine.UIElements;

public class Click : MonoBehaviour
{
    private int intnum;
    GameObject[] ClickableObject;
    Material[] outline;
    Component[] iMat;
    void Start()
    {
        ClickableObject = GameObject.FindGameObjectsWithTag("Clickable Objects");
        foreach (GameObject i in ClickableObject)
        {
            intnum=0;
            iMat=i.GetComponents<MeshRenderer>();
            
        }
    }

    // Update is called once per frame
    void Update()
    {
        if (Input.GetMouseButton(0))
        {
            
        }
    }
    public void Unclicked()
    {
        foreach (Material e in iMat)
        {
            if (iMat[intnum].name == "Outline Material")
            {
                intnum++;
            }
            else
            {
                intnum++;
            }
        }
        foreach (GameObject i in ClickableObject)
        {
            
        }
    }
}

You have a lot of issues with your code. Honestly, it doesn't make any sense. First, It doesn't compile: "Material e in iMat". This just keeps overwriting the array on each loop: iMat=i.GetComponents<MeshRenderer>(); You might want to use List<MeshRenderer> and use AddRange to the list in each loop. You're getting MeshRenderers but then attempting to store it iMat. iMat contains MeshRenderers, not materials. Materials are part of a MeshRenderer using meshRenderer.materials

Thanks i know my code has a lot of issues as i only started a few weeks ago, and iMat was orignally used to store materals hence the name but i couldn't make it work.

To make it a bit more simple you could use this asset here for outlines (https://assetstore.unity.com/packages/tools/particles-effects/quick-outline-115488), all you do is put the outline script on the object you want the outline on and then just enable/disable the script for on/off, might be easier for you than changing the materials themselves. Let me know if this works for your situation and ill submit it as answer rather than a comment :)
