My unity project is freezing and there are no errors before clicking play button after that it freezes the code:

In this code I am trying to detect if the player is triggering enemy collider with OnTriggerStay2D so if it does I want the code to add score every second with IEnumerator function. But if the player is not colliding with the enemy for more than 2 seconds it gets destroyed.

The code:

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

public class Trigger : MonoBehaviour
{
    public GameObject other;
    bool touching = false;
    int score = 0;

    public void Update()
    {
        AddScore();
    }

    private void OnTriggerStay2D(Collider2D other)
    {
        Debug.Log("Touching");
        touching = true;
    }

    public void AddScore()
    {
        if(touching == true)
        {
            while (touching == true)
            {
                score  ;
                StartCoroutine(wait());
            }
            Debug.Log(score);
        }
        else
        {
            Debug.Log("Not Touching");
            StartCoroutine(waiter());
        }
    }

    IEnumerator waiter()
    {
        yield return new WaitForSecondsRealtime(2);
        Destroy(other);
    }

    IEnumerator wait()
    {
        yield return new WaitForSecondsRealtime(1);
    }
}

CodePudding user response：

Just delete while (touching == true), that is breaking your game.

The if condition should be enough for the logic.
