Hey here is the code:

int in editor is equal 10

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

public class deadlyPlant : MonoBehaviour
{

public int damagetime;

public void OnTriggerEnter2D(Collider2D other)
{
    if (other.tag == "Player")
    {

        StartCoroutine(StartTakingDamage());

    }

}
IEnumerator StartTakingDamage()
{
    while (damagetime > 0)
    {
        yield return new WaitForSeconds(4f);
        damagetime --;
        Debug.Log(damagetime);
        
    }
    
}

}

As far as I remember decrementation decrease variable by 1, but Debug in editor shows that every secound int was decreased by 1 twice. Cen some one tell me why? Maybe there is some thing wrong with loop? Please help me understand why it`s working like that.

Thx,Hey, here is th code

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

public class deadlyPlant : MonoBehaviour
{

public int damagetime;

public void OnTriggerEnter2D(Collider2D other)
{
    if (other.tag == "Player")
    {

        StartCoroutine(StartTakingDamage());

    }

}
IEnumerator StartTakingDamage()
{
    while (damagetime >= 0)
    {
        yield return new WaitForSeconds(4f);
        damagetime --;
        Debug.Log(damagetime);
        
    }
    
}

}

Int = 10 in editor

As far as I know decrementation decrese variable by 1 but Debug every 4 secounds decrease number by 1 twice. Its probably something with my code. Im beginner so can someone help me understand why it`s working that way?
