using UnityEngine.SceneManagement;

public class Damag : MonoBehaviour
{
public float health = 100;
public float times;
public float trigger;

void Update()
{


times * Time.deltaTime;


if (health <= 0){

SceneManager.LoadScene(SceneManager.GetActiveScene().level1);
}
}


void OnTriggerEnter(Collider other)
{
if (other.gameObject.CompareTag("player")) {

trigger = 1;
}
}

void OnTriggerEnter(Collider other)
{

trigger = 0;

}

void damage()
