How To Properly Instantiate UI Objects

Hello,

There are times where we need to instantiate multiple prefabs instantly. Like leaderboard table that has around 100 elements. We usually instantiate them using coroutines like;

    IEnumerator InstantiateStuff()
    {
        foreach(GameObject _gameObject in gameObjects)
        {
            yield return new WaitForSeconds(0.2f);
            Instantiate(_gameObject, transform.parent);
        }
    }

to prevent the main thread from freezing. But is there a more “proper” way to instantiate objects faster and more efficient way?

Edit: We’re aware of object pooling but due to memory restrictions, we can’t use pooling option efficiently.

I’m not sure about a better way to instantiate something like leaderboards in your case, I think that spawning them in a coroutine is not a bad way to go.

I will say, however, that you should probably not do
yield return new WaitForSeconds(0.2f);

As far as I know that is creating a new object every time that code executes. You could save the wait for seconds object at the beginning of the routine
WaitForSeconds wait = new WaitForSeconds(0.2f)
and then say
yield return wait;

But that also feels like a long time to wait to spawn what should be pretty simple prefabs. Are you able to try just
yield return null

That would spawn one per frame- probably a lot faster if you’re trying to spawn around 100 UI elements.
