StackOverflowException: The requested operation caused a stack overflow. Please can someone help me solve this.
I was trying to make a dismemberment of my enemy when my sword collides with him. This script is in all the parts that i want to dismember.
This is the erro:
StackOverflowException: The requested operation caused a stack overflow.

This is the script that is causing this:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class Limb : MonoBehaviour
{
[SerializeField] Limb[] ChildLimbs;
// Start is called before the first frame update
void Start()
{
}
// Update is called once per frame
void Update()
{
}
public void OnCollisionEnter(Collision collision)
{
if(collision.gameObject.tag == "Sword")
{
GetHit();
}
}
public void GetHit()
{
if(ChildLimbs.Length > 0)
{
foreach (Limb limb in ChildLimbs)
{
if(limb != null)
{
limb.GetHit();
}
}
}
// transform.localScale = Vector3.zero;
Destroy(gameObject);
}
}
There's not much to say about this. You clearly have either:
This Limb instance referenced in his own "ChildLimbs" array so you simply call your own "GetHit" method from within your GetHit method in an infinite recursion
or you referenced this Limb instance from one of the child Limbs and get a similar result. In any case you have a circular reference and you just running circles until you get a stack overflow since every nested method call requires a stackframe.
So there's not really something wrong in your code (even though it's dangerous the way it's setup) your actual issue is in the way you setup the references in your "ChildLimbs" collection(s). A seemingly strange solution would be to move
Destroy(gameObject);
to the top of your GetHit method. This should ensure that your Limb component is marked "destroyed" so your null check inside your for loop would filter out those you already destroyed.
