플레이어에 발사 스크립트 붙임 

- 발사하기 

- 오디오 추가하기 

- 발사지점 효과 넣기  muzzleFlash

using System.Collections.Generic;
using UnityEngine;

public class FireCtrl : MonoBehaviour
{
    public GameObject bulletprefab;
    public Transform firepoint;

총알이 충돌할 경우 사라지는 스크립트 

스파크 효과 넣기 

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

public class RemoveBullet : MonoBehaviour
{
    public GameObject sparkEffectPrefab;
    private void OnCollisionEnter(Collision collision)
    {
        if (collision.collider.CompareTag("Bullet"))
        {
            //첫번째 충돌 지점의 정보 추출 
            ContactPoint contactPoint = collision.contacts[0];

            DrawArrow.ForDebug(contactPoint.point, -contactPoint.normal, 10, Color.red);

            //충돌한 총알의 법선 벡터를 쿼터니언으로 변환 
            Quaternion rot = Quaternion.LookRotation(-contactPoint.normal);


           GameObject spark= Instantiate(sparkEffectPrefab,collision.transform.position,Quaternion.identity);

            Destroy(spark,0.5f);


            Destroy(collision.gameObject);
        }
    }

드럼통 컨트롤러

- 총알 3번 맞으면 위로 날아가면서 폭발하기

- 폭발 주변 반경으로 간접 영향 주기

- 폭발 효과 넣기 

- 드럼통 텍스처 3종 랜덤으로 변하기
