Removing objects from an array

Questions & Answers
1

Hey everyone. I have AI enemies and some weapon meshes. These meshes have C# scripts attached to them that damage the enemies. But, there’s only one target (as a GameObject) it can lock on to. I’m using arrays (not List<>, just arrays) to handle this, but I want it to remove an object from the array when it dies. Is there a way to that? Thanks.

Here’s one of the scripts:

using UnityEngine;
using System.Collections;

public class HammerDamage : MonoBehaviour {
	public GameObject[] targets;
	public GameObject target;
	public float attackTimer;
	public float coolDown;

	// Use this for initialization
	void Start () {
		attackTimer = 0;
		coolDown = 2.0f;
		
	//	targets = GameObject.FindGameObjectsWithTag("Enemy 3").Select(g=>g.transform).ToList();
	
	}
	
	// Update is called once per frame
	void Update () {
		if(attackTimer > 0)
			attackTimer -= Time.deltaTime;
		
		if(attackTimer < 0)
			attackTimer = 0;
		
		if(Input.GetKeyUp(KeyCode.F)) {
			if(attackTimer == 0) {
				HammerAttack();
				attackTimer = coolDown;
			}
		}
	}
	
	public void HammerAttack() {
		GameObject[] gos = GameObject.FindGameObjectsWithTag("Enemy 3");
		
		targets = gos;
		
	//	target = gos;
		
		float distance = Vector3.Distance(target.transform.position, transform.position);
		
		Vector3 dir = (target.transform.position - transform.position).normalized;
		
		float direction = Vector3.Dot(dir, transform.forward);
		
		Debug.Log(direction);
		
		if(distance < 2f) {
			if(direction < 0) {
				EnemyHitPoints ehp = (EnemyHitPoints)target.GetComponent("EnemyHitPoints");
				ehp.AdjustCurrentHitPoints(-45);
//		EnemyHealth eh = (EnemyHealth)target.GetComponent("EnemyHealth");
//		eh.AddjustCurrentHealth(-45);
			}
		}
	}
}

System.Collections.Generic.List list = new System.Collections.Generic.List(targets);
list.Remove(targetObject);
targets = list.ToArray();

If you don’t want to uses generics or at all you can also do:

for (int i = 0; i+1 < targets.Length;i++)
{
    if(targets *== targetObject)*

{
targets = targets[blocks.Length -1];
break;
}
}
Array.Resize(ref targets, targets.Length - 1);
