How do you access components of a array with game objects?

Unity Engine
1

Hey guys im trying to make a script where the code takes all the objects in the game and deals 100 damage to them. I use an array to get all the objects however i dont know how to get all their components at once and deal damage to them. If you guys could help it would be much appreciated. Thanks Beforehand :slight_smile:

Code:

var explosion : GameObject;
var BlastRadius : int = 10;
var Damage : int = 100;
var Radius : float = 10.0;
var Enemy : AIdamage;
var Enemies : GameObject[];
private var center : Vector3;

private var hitTarget  : GameObject;

function update (){

    Enemies = GameObject.FindGameObjectsWithTag("Enemy");

}

function OnCollisionEnter(hitTarget : UnityEngine.Collision)
{
  
     Enemies.GetComponents("AIdamage").CurrentHealth -= Damage;



}

Try foreach()…that should do it

Sry to bother but I tried and messed it up could you please give me an example of how i can implement it?

c# example of how to access the AIDamage classes and check for hits with Physics.OverlapSphere:

using UnityEngine;
using System.Collections;

public class ExplosionExample : MonoBehaviour
{
    public GameObject explosionEffect;
    public float damage=5, blastRadius=10;

    bool firstCollision=true;

    void OnCollisionEnter(Collision col)
    {
        if(firstCollision)
        {
            firstCollision=false;

            Collider[] hitColliders = Physics.OverlapSphere(transform.position, blastRadius);

            for(int i=0;i<hitColliders.Length;i++)
            {
                if(hitColliders[i].CompareTag("Enemy"))
                {
                    hitColliders[i].GetComponent<AIDamage>().CurrentHealth -= damage;
                }
            }
        }

        //explosionEffect
    }
}

if you want to avoid using GetComponent too much for some reason, one way to do so is to use a dictionary from System.Collections.Generic to store the AIDamage classes

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

public class ExplosionExample2 : MonoBehaviour
{
    public GameObject explosionEffect;
    public float damage=5, blastRadius=10;

    Dictionary<Collider,AIDamage>enemyScripts=new Dictionary<Collider, AIDamage>();

    void Start ()
    {
        GameObject[] hitTargets;
        hitTargets=GameObject.FindGameObjectsWithTag("Enemy");

        for(int i=0; i<hitTargets.Length; i++)
        {
            enemyScripts.Add(hitTargets[i].GetComponent<Collider>(),hitTargets[i].GetComponent<AIDamage>());
        }
    }

    bool firstCollision=true;

    void OnCollisionEnter(Collision col)
    {
        if(firstCollision)
        {
            firstCollision=false;

            Collider[] hitColliders = Physics.OverlapSphere(transform.position, blastRadius);

            for(int i=0;i<hitColliders.Length;i++)
            {
                if(hitColliders[i].CompareTag("Enemy"))
                {
                    enemyScripts[hitColliders[i]].CurrentHealth -= damage;
                }
            }
        }

        //explosionEffect
    }
}

Thanks for the help but would it still work in Javascript? Since im not very good with C# sry :frowning:
Im kind of new to Unity :confused:

Also, Whats with the first collision bollean?
