delay in start of script,delay a object before update

Questions & Answers
1

I’m attempting to create a delay in the script start so not all my objects start at the same pulsing at the same time. All my script does is create a pulsing effect that I’ve added to all my prefab objects. I then spawn all the objects at random within my map.

I’ve attempted to do what I found on unity’s API but alas, to no end.

void Start()
{
    shrinking = true;
    slowDown = false;
    new WaitForSeconds(Random.Range(0,5);
}

here is the script as a whole

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

public class DNAPulse : MonoBehaviour
{
    public float targetScale = 0.5f;
    public float shrinkSpeed = 0.3f;
    public float enlargeSpeed = 0.5f;
    public float slowEffect = 0.05f;
    private bool shrinking;
    private bool slowDown;

    void Start()
    {
        shrinking = true;
        slowDown = false;

    }
    void Update()
    {
        if (shrinking)
        {
            transform.localScale -= Vector3.one * Time.deltaTime * shrinkSpeed;
            //if (transform.localScale < Vector3.one)
            Debug.Log(transform.localScale.x);
            if (transform.localScale.x < targetScale)
            {
                shrinking = false;
            }
        }
        else if (!slowDown)
        {
            transform.localScale += Vector3.one * Time.deltaTime * enlargeSpeed;
            if (transform.localScale.x > targetScale * 2)
                slowDown = true;
        }
        if (slowDown)
        {
            transform.localScale += Vector3.one * Time.deltaTime * slowEffect;
            if (transform.localScale.x > targetScale * 2.2)
            {
                slowDown = false;
                shrinking = true;
            }
        }
    }
}

You are using the API incorrectly. You need to use CoRoutines:

bool waitingToStart = true;

void Start()
{
	waitingToStart = true;
	shrinking = true;
	slowDown = false;
	StartCouRoutine(WaitFor(Random.Range(0,5)));
}

IEnumerator  WaitFor (float time) {
	yeild return new WaitForSeconds (time);
	waitingToStart = false;
}

void Update()
{
	if (waitingToStart)
		return;

	if (shrinking) {
		...
	}
	...
{
