How to destroy two cloned cards when matched in memory card game?
using System.Collections.Generic; using UnityEngine; using System.Collections; using UnityEngine.SceneManagement;
public class SceneController_animal : MonoBehaviour {
public GameObject teacher;
public const int gridRows = 2;
public const int gridCols = 4;
public const float offsetX = 4f;
public const float offsetY = 4.8f;
[SerializeField]
private MainCard_animal originalCard;
[SerializeField]
private Sprite[] images;
private void Start()
{
Vector3 startPos = originalCard.transform.position; //The position of the first card. All other cards are offset from here.
int[] numbers = { 0, 0, 1, 1, 2, 2, 3, 3 };
numbers = ShuffleArray(numbers);
for(int i = 0; i < gridCols; i++)
{
for(int j = 0; j < gridRows; j++)
{
MainCard_animal card;
if (i == 0 && j == 0)
{
card = originalCard;
}
else
{
card = Instantiate(originalCard) as MainCard_animal;
}
int index = j * gridCols + i;
int id = numbers[index];
card.ChangeSprite(id, images[id]);
float posX = (offsetX * i) + startPos.x;
float posY = (offsetY * j) + startPos.y;
card.transform.position = new Vector3(posX, posY, startPos.z);
}
}
}
private int[] ShuffleArray(int[] numbers)
{
int[] newArray = numbers.Clone() as int[];
for(int i = 0; i < newArray.Length; i++)
{
int tmp = newArray[i];
int r = Random.Range(i, newArray.Length);
newArray[i] = newArray[r];
newArray[r] = tmp;
}
return newArray;
}
private MainCard_animal _firstRevealed;
private MainCard_animal _secondRevealed;
private int _score = 0;
[SerializeField] private TextMesh scoreLabel;
public bool canReveal
{
get { return _secondRevealed == null; }
}
public void CardRevealed(MainCard_animal card)
{
if(_firstRevealed == null)
{
_firstRevealed = card;
}
else
{
_secondRevealed = card;
StartCoroutine(CheckMatch());
}
}
private IEnumerator CheckMatch()
{
if(_firstRevealed.id == _secondRevealed.id)
{
_score++;
scoreLabel.text = "Score: " + _score;
Destroy(_firstRevealed);
Destroy(_secondRevealed);
}
else
{
yield return new WaitForSeconds(0.5f);
_firstRevealed.Unreveal();
_secondRevealed.Unreveal();
}
_firstRevealed = null;
_secondRevealed = null;
if (_score == 4)
{
}
}
}
Comment
'Destroy(_firstRevealed); and Destroy(_secondRevealed)' do not work at all. <-- I think this may be wrong. And I don't know how to hold cloned cards and how to define cloned cards as 'GameObject'. Help. Thank you very much, in advance.

Maincard_animal is just a reference to the script, not the object/prefab itself.
You can use:
GameObject card = Instantiate(originalCard.gameObject) as GameObject;
If the objects are instantiating as GameObjects already, you may just need to use
Destroy(_firstRevealed.gameObject);
