C# Check if Collider2D[] Doesn't contain Scripted GameObject
Is there a way to check if a Collider2D[] doesn't contain the gameobject it's attached to and/or exclude it? I have a scripted gameobject with a collider and Physics2D.OverlapCircleAll returns with that collider when I only want it to return only the colliders around the gameobject.
public Collider2D[] hitColliders;
void Update (){
hitColliders = Physics2D.OverlapCircleAll(transform.position, 5f);
}
Best Answer
You can loop through the hitColliders array to find out the gameobject and then exclude it.
Something like:
using UnityEngine;
using System.Collections;
using System.Collections.Generic;
public class ExcludeScript : MonoBehaviour {
public List<Collider2D> hitColliders;
void Update (){
Collider2D[] hitResult = Physics2D.OverlapCircleAll(transform.position, 5f);
hitColliders = new List<Colider2D>();
for(int i = 0; i < hitResult.Length; i++)
{
// if the transform of this collider's GO is not same as this GO's transform then it add it to the list
if(hitResult[i].transform != this.transform)
{
hitColliders.Add(hitResult[i]);
}
}
//Once done you can even convert this list to an array
hitColliders.ToArray();
}
}
