How to hide/show object on UI button click?

Question

Unity

I have a "Shop" in my game on Unity, in it you can buy a "card", when you buy it, it turns out to be in your hands. How can I make it so that it can be hidden and shown?

Answer 1

[SerializeField]
private GameObject card; // твоя карта

public void BuyACard()
{
    card.SetActive(true);
}
