[24.02.16]Unity - 개인(MiniGame)

배웠던걸 가지고 캐릭터가 마우스로 클릭으로 이동을 하고

코인먹으면 코인점수가 오르는 게임을 대충 만들어보자.

우선 전 프로젝트에서 코인모양의 오브젝트를 추가해준다(물론 머테리얼도) 그리고 태그도 코인으로 넣어줍니다.

그리고 공에 트리거를 온 해두고

Area 라는 빈 프로젝트를 만들어

랜덤으로 공이 나올곳을 지정해줍니다.

    private void Awake()
    {
        area = GetComponent<BoxCollider>();
    }
    void Start()
    {



        for (int i = 0; i < count; ++i)//count 수 만큼 생성한다
        {
            Spawn();//생성 + 스폰위치를 포함하는 함수
        }

        area.enabled = false;
    }

    private Vector3 GetRandomPosition()
    {
        Vector3 basePosition = transform.position;
        Vector3 size = area.size;

        float posX = basePosition.x + Random.Range(-size.x / 2f, size.x / 2f);
        float posY = basePosition.y + Random.Range(-size.y / 2f, size.y / 2f);
        float posZ = basePosition.z + Random.Range(-size.z / 2f, size.z / 2f);
