Acho que não precisa explicar o Basic Settings, pq é bem intuitivo.


Prefab_Effect_all = prefab que vai ser instanciada em qualquer gameObject que não tenha o Componente do inimigo.
Prefab_Effect_enemy = prefab que vai ser instanciada em qualquer gameObject que tenha o Componente do inimigo.


TMP Text Settings = Textos do canvas.

Código:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class Enemy : MonoBehaviour
{
    [SerializeField] private float _LifeEnemy = 200;
    public float EnemyLife
    {
        get => _LifeEnemy;
        set => _LifeEnemy = value;
    }

    void Update()
    {
        if(_LifeEnemy <= 0)
        {
            Dead();
        }
    }

    void Dead()
    {
        Destroy(gameObject, 1f);
    }
}


Nele só vai estar a vida.

Código:

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

public class Bullet : MonoBehaviour
{
    [Range(1, 50)]
    public int bullet = 15;
    public float _DistancePlayer = 1.5f;
    public KeyCode _key = KeyCode.F;
    public AudioClip sound;
    bool a = true;

    void Update()
    {
        GameObject p;
        p = GameObject.FindWithTag("Player");
        var player =  p.GetComponentInChildren<Weapon>();
        var _aud = p.GetComponent<AudioSource>();
        float d = Vector3.Distance(transform.position, player.gameObject.transform.position);
        if(d < _DistancePlayer && Input.GetKeyDown(_key) && a == true)
        {
            player.AinBag += bullet;
            a = false;
            _aud.clip = sound;
            _aud.Play();
            Destroy(gameObject);
        }
    }
}


Coloque ela no objeto que você deseja, que seja a munição no seu game.

Vlw tu consegue colocar os áudios pra baixar?

Você pode baixar do repositório que deixei acima.



Clica no áudio.



Aí só baixar.

Update, coloquei Unity Events nos tiros e no reload. Assim pode chamar algo quando você atirar ou recarregar a arma, por exemplo uma animação.
