I'm trying to check when the player collides with a clone of the coin prefab, but I don't know how to reference the clone

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class CoinSpawning : MonoBehaviour
{
public GameObject coinPrefab;

private void OnCollisionEnter(Collision other)
{
    if (other.gameObject.name == "Coin" || other.gameObject == coinPrefab)
    {
        StartCoroutine(coinSpawn());
        Destroy(other.gameObject);
    }
}
IEnumerator coinSpawn()
{
    yield return new WaitForSeconds(3f);
    spawnCoin();
}
private void spawnCoin()
{
    
    GameObject a = Instantiate(coinPrefab) as GameObject;
    a.transform.position = new Vector3(Random.Range(-50, 50), Random.Range(1, 2), Random.Range(-50, 50));
}

}

If you don’t like using tags you can accomplish this with small changes, when Instantiate creates a game object it sets the name to “Coin (clone)”.

you can change your OnCollisionEnter to if (other.gameObject.name.Contains("Coin"))

or you can modify spawnCoin() and set a name for the new game object like so:

GameObject a = Instantiate(coinPrefab) as GameObject;
a.name = "Coin";

@drthirtle So I’m new to this as well but this may help.

When you instantiate a new game object it is created with the name “Coin (clone)”. You are checking for just “Coin”.

Either name the game object when creating it like so:

spawnCoin() {
    GameObject a = Instantiate(coinPrefab) as GameObject;
    a.name = "Coin";
    ...
}

or in your collision check use:

if (other.gameObject.name.Contains("Coin")) {...}

Let me know if this was helpful :slight_smile:

If I understand correctly, I think you should use tags. For example, set the coinPrefab’s tag to “Coin”, and in OnCollisionEnter check whether other.gameObject has that tag or not.
