I am just trying to spawn obstacle but the obstacle gets cloned every frame

Scripting C# & .NET

using UnityEngine;

public class ObstacleSpawner : MonoBehaviour
{
[SerializeField] private GameObject obstaclePrefab; // Prefab for the obstacle
[SerializeField] private GameObject player; // Reference to the player
private bool isGenerated = false;

void Update()
{
    GenerateObstacle();
}

void GenerateObstacle()
{
    Vector3 spawnPos = new Vector3(20f, -1.5f, player.transform.position.z);
    
    if (!isGenerated)
    {
        Instantiate(obstaclePrefab, spawnPos, Quaternion.identity); // Spawn the obstaclePrefab
        isGenerated = true; // Set the flag to true to prevent further spawning
    }
}

}

Is this component on the obstacle prefab itself? If so, every time you spawn one, it will spawn another.

yep the script was the comonent of prefab and it was causing the problem thanks for the answer.
