There are so many ways how you can do it.
Here is a one of many ways. It is proposed that all coins already placed on scene with tag "coin". This example is not so good, i would use events instead of link to GameManager from all coins, but this example is easier to understand.
public class GameManager : MonoBehaviour
{
// Attach this script anywhere on a scene
// Set here the link to your KeyGameObject on scene
public GameObject keyGameObject;
int coinsTotalCount;
int coinsCollected = 0;
void Awake()
{
// Disable your KeyGameObject
keyGameObject.SetActive(false);
// Get how many coins on scene
coinsTotalCount = GameObject.FindGameObjectsWithTag("Coin").Length;
}
// Call this method from CoinScript each time you collect coin
public void CoinCollected()
{
coinsCollected++;
// If you collected all coins - show KeyGameObject
if (coinsCollected == coinsTotalCount)
keyGameObject.SetActive(true);
}
}
public class Coin : MonoBehaviour
{
// Attach this script to coin prefab
// Set this link in prefab to your GameManager on scene
public GameManager gameManager;
void OnCollect()
{
gameManager.CoinCollected();
Destroy(gameObject);
}
}
