Vertical 2D Shooting 07 : UI 일부 구현 (점수, 생명)

점수 UI

 

Text UI 배치

빈 오브젝트 Director + 스크립트 Director

 

감독 스크립트

플레이어 사망

 

Enemy 태그의 콜라이더와 충돌시 생명 감소

 

private void OnTriggerEnter2D(Collider2D collision)
    {
        if (collision.CompareTag("Enemy"))
        {
            if (this.life > 0)

                Debug.LogFormat("Life : {0} / Hit", this.life);
                this.life -= 1;
            }
            else
            {
                Debug.Log("GameOver");

UI와 연결하기

 

private void OnTriggerEnter2D(Collider2D collision)
    {
        if (collision.CompareTag("Enemy"))
        {
            if (this.life > 0)
            {
                GameObject life = GameObject.Find("Life");
                life.transform.GetChild(this.life - 1).gameObject.SetActive(false);
                this.life -= 1;
            }
            else
            {
                Debug.Log("GameOver");

                //사망하면 비활성화(임시)
                this.gameObject.SetActive(false);
            }
        }
    }

 

GameObject life = GameObject.Find("Life"); life.transform.GetChild(this.life - 1).gameObject.SetActive(false); Image UI의 인덱스로 자식에 접근하여 비활성화 (life변수를 인덱스로 사용)
