unity-16: collision이용한 발사체 효과

    public GameObject _hitEffectObj;
    void OnCollisionEnter(Collision other)
    {
        if (other.gameObject.CompareTag("CannonBall"))
        { 
            Destroy(other.gameObject, 0.1f);
            Instantiate(_hitEffectObj, other.transform.position, _hitEffectObj.transform.rotation);
        }
    }

• CompareTag("태그이름")으로 태그이름에 해당하는 것만 작동되게 하기
• cannonball만 부딪히면 터지게 만듦
• 히트오브젝트라는 게임오브젝트의효과를, 부딪히는 오브젝트의 위치와, wall의 방향으로 생성
• effect효과 넣어주기

벽을 5번 맞추면 터지게 하기

    public int _durationHit = 5;
    public GameObject _effectdty;
    public GameObject _hitEffectObj;
    void OnCollisionEnter(Collision other)
    {
        if (other.gameObject.CompareTag("CannonBall"))
        { 
            Destroy(other.gameObject, 0.1f);
            GameObject go = Instantiate(_hitEffectObj, other.transform.position, _hitEffectObj.transform.rotation);
            _durationHit--;
            Destroy(go, 1);

            if (_durationHit <= 0)
            {
                go = Instantiate(_effectdty, transform.position, _effectdty.transform.rotation);
                Destroy(gameObject);
                Destroy(go, 1);
            }
        }
    }

투명 원형에 통과할때 효과생기게 하기

    public int _durationHit = 10;
    public GameObject _effectdty;
    public GameObject _hitEffectObj;

    void OnCollisionEnter(Collision other)
    {
        if (other.gameObject.CompareTag("CannonBall"))
        { 
            Destroy(other.gameObject, 0.1f);
            GameObject go = Instantiate(_hitEffectObj, other.transform.position, _hitEffectObj.transform.rotation);
            _durationHit--;
            Destroy(go, 1);

            if (_durationHit <= 0)
            {
                go = Instantiate(_effectdty, transform.position, _effectdty.transform.rotation);
                Destroy(gameObject);
                Destroy(go, 1);
            }
        }
    }

    void OnTriggerEnter(Collider coll)
    {
        if (coll.CompareTag("CannonBall"))
        {
            Destroy(coll.gameObject, 0.1f);
            GameObject go = Instantiate(_hitEffectObj, coll.transform.position, _hitEffectObj.transform.rotation);
            _durationHit--;
            Destroy(go, 1);

            if (_durationHit <= 0)
            {
                go = Instantiate(_effectdty, transform.position, _effectdty.transform.rotation);
                Destroy(gameObject);
                Destroy(go, 1);
            }
        }
    }

-sphere-

    // Start is called before the first frame update
    public GameObject _effectEnter;
    public GameObject _effectExit;


    void OnTriggerEnter(Collider col)
    {
        if (col.CompareTag("CannonBall"))
            Instantiate(_effectEnter, col.transform.position, _effectEnter.transform.rotation);
    }

    void OnTriggerExit(Collider col)
    {
        if (col.CompareTag("CannonBall"))
            Instantiate(_effectExit, col.transform.position, _effectExit.transform.rotation);
    }

• sphere만들고, material만들어서 드래그.
• material renderingMode를 transparent로 , Emission에서 color에서 선택하고, color에서 A를 약하게
• cannonball을 istrigger 체크!(벽은 다른물체를 막아야함) -> 벽마저 통과함 → wall에서 istrigger체크된 cannonball을 막아야함 → wall의 script에서 OntriggerEnter로 설정
• sphere script만들고 wall에 넣어줌
• 들어갈때 나갈때 효과 넣어줌
• OntriggerEnter와 OntriggerExit 사용
