Is it possible to make a function not trigger again for a set time?

Question

Let me start by saying in kinda a newbie, so keep it simple please lol

I was trying to make a portal to teleport an object in Unity. I couldn't figure it out so I looked up a tutorial and found this bit of code. It works fine, except for one tiny issue. The object going through the portal (I just used a sphere) will go back and forth constantly between the portal, essentially becoming stuck in a loop. Is there a way to set a buffer or "cooldown time" on the function so it wont trigger again immediately? I put this code on both of the portals and set the "spawnPoint"s to the other portal. So the orange portal's spawnPoint was the blue portal and vice versa. Here's the code.

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

public class Portal : MonoBehaviour
{

    public Transform spawnPoint;
   
    // Update is called once per frame
    void OnTriggerEnter(Collider other)
    {
        other.gameObject.transform.position = spawnPoint.position;
    }
}

let me know if I wasn't clear enough.

Answer 1

one of many options is to use coroutines https://docs.unity3d.com/Manual/Coroutines.html

Like this.

    bool canBeUsed = true;

    void OnTriggerEnter(Collider other)
    {
        if(canBeUsed)
        {
            canBeUsed = false;

            StartCoroutine(Example());

            other.gameObject.transform.position = spawnPoint.position;
        }
    }

    IEnumerator Example()
    {
        yield return new WaitForSeconds(5);
        canBeUsed = true;
    }

One Variable for more than one portal.

Option 1:

create empty object and rename it. Maybe call it "PortalManager". Then create new script like this below and ad it to our PortalManager object. https://prnt.sc/12rlzny

using UnityEngine;

public class PortalsManager : MonoBehaviour
{
    public static bool CanBeUsed = true;
}

Then the portal script will look like this:

using System.Collections; using UnityEngine;

public class test : MonoBehaviour
{
    void OnTriggerEnter(Collider other)
    {
        if (PortalsManager.CanBeUsed)
        {
            PortalsManager.CanBeUsed = false;

            StartCoroutine(Example());

            Debug.Log("AAAA");

            //  other.gameObject.transform.position = spawnPoint.position;
        }
    }

    IEnumerator Example()
    {
        yield return new WaitForSeconds(5);
        PortalsManager.CanBeUsed = true;
    }
}

Option 2:

Dont create new object. Just create script like this:

public static class PortalsManager
{
    public static bool CanBeUsed = true;
}

The code in portals will be exactly like this from option 1

All this i tested live :)
