4. EnemyCaptainController

 

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

public class AutoBombDestroy : MonoBehaviour
{
    public void DestroyObject() //이벤트 핸들러 메서드
    {
        GameObject parentObject = gameObject.transform.parent.gameObject;
        Destroy(parentObject);
    }
}

5. AutoBombDestroy.cs

 

using UnityEngine;

public class ReturnIdle : MonoBehaviour
{
    private Animator anim; 

    void Start()
    {
        anim = GetComponent<Animator>();
      
    }

    public void ResetToIdle()
    {
        anim.SetInteger("State", 0); // Idle 상태로 설정

    }
}

6. ReturnIdle.cs

 

 

코루틴 까지는 금방 했는데,

애니메이션 이벤트에서 한번 꼬여가지고 고생한 것 같다.

그래도 막혔던 부분을 해결하니

또 하나 배운 것 같다.

 

적(Captain)이 죽을 떄 넉백되면서 죽게 만들고 싶었는데

자꾸 parameter에서 ignore가 뜨면서 애니메이션 실행에 문제가 발생해서

그 부분이 좀 아쉽긴 하다.
