i am writing a game that when it is run, cards are dealt out of the deck one by one(that means you should be able to see a card flow out of the deck, takes another position then the next one also gets out of the deck until all the card are finished from the deck), now the one i have written cards flow out of the deck at once and they take up another position.

your text i expected the cards to get out of the deck one by one but the deck expands a bit and cards are still packed together while moving out of the deck
