Hi @KejuPilihan !

First off, I just want to share some links to resources that may provide more thorough answers & explanations than I’m about to provide here:

Now as for your specific code…

I believe the issue you’re hitting is that you’re never actually starting your “SpawnAgain” IEnumerator method as a Coroutine - instead you are simple calling SpawnAgain directly.

Probably the best way for you to call it would be to use:

StartCoroutine(SpawnAgain());

which will allow the 'yield" to actually wait for the random 1 to 5 seconds.

If you want more control, such as the ability to start multiple SpawnAgain() Coroutines at the same time, or to Stop specific running coroutines, you can do something more like:

private IEnumerator currentSpawnAgainCoroutine = null;

IEnumerator SpawnAgain()
{
    // your code that was already in here
}

private void OnTriggerEnter2D(Collider2D collision)
{
    if (collision.name == "GameOverTrigger")
    {
        if (currentSpawnAgainCoroutine != null) StopCoroutine(currentSpawnAgainCoroutine);
        
        currentSpawnAgainCoroutine = SpawnAgain();
        StartCoroutine(currentSpawnAgainCoroutine);
    }
}

That will make sure you stop any already-running SpawnAgain() coroutine in the currentSpawnAgainCoroutine variable (if any) before running a new one - which is good for keeping your memory less leaky.
