Make object invisible on start

I trying to make a object invisible on start and when collision happened it will appear. So I decide to disable the sprite renderer. But when I click play the object is still visible.

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

public class pg10_dropSeed : MonoBehaviour
{
    private SpriteRenderer seedRender;
   
     void Start()
    {
       seedRender = GetComponent<SpriteRenderer>();
        seedRender.enabled = false;
    
       
           
    }
}

I am working on a similar feature!
You may try moving “seedRender.enabled = false” after void Update (); below please find my code:

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

public class SpriteReaction : MonoBehaviour
{
    SpriteRenderer rend;

    // Start is called before the first frame update
    void Start()
    {
        rend = GetComponent<SpriteRenderer>();
    }

    // Update is called once per frame
    void Update()
    {
        this.rend.enabled = false;
    }
}

Otherwise, have you add the script to the object, and, if you have seen the box for “Sprite Renderer” unchecked when the game starts?

Hope it helps!
