I tried to make a Flashlight Battery Script but it’s dont work. Can someone help me?
-BATTERY SCRIPT:

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

public class Baterias : MonoBehaviour
{
public Flashlight flashlight;

[SerializeField] public int batteries = 2;

public void OnTriggerEnter(Collider other)
{
	if (other.CompareTag("Player"))
	{

		GameObject.FindGameObjectWithTag("Flashlight").GetComponent<Flashlight>().batteries = 2;
		flashlight.batteries += 2;

		Destroy(this.gameObject);

	}
}

}

@pwolf1897 , can you try this out?

public void OnTriggerEnter(Collider other)
{
    if (other.transform.tag=="Player")
    {
        other.GetComponent<Flashlight>().batteries += 2;
        Destroy(this.gameObject);
    }
}

But in Case that Flashlight script is in child of object that has collider just set

other.GetComponentInParent<Flashlight>().batteries += 2;

Or if Flashlight script is a child of your object that has collider that triggers it then set

other.GetComponentInChildren<Flashlight>().batteries += 2;

Also this will only work if ur collider that triggers the battery collider is on the same object as the flashlight Script,and check if the collider on the battery is set as trigger! Also remember to check if collider on your player is tagged as “Player” this must be exactly same!

@JethRow It’s doesn’t work. :frowning: I Upload some ScreenShots maybe it can help.
Here’s more screenshots:

Check if your flashlight has a box collider/sphere collider and then tick the “isTrigger” box. It should probably work but
If it doesn’t have any collider, go to add component search “box collider” if it is cube shaped or “sphere collider” if it is sphere shaped. If this doesn’t work see if your player has the tag you have written
