Unity 學習筆記 - 設置手機螢幕邊框的透明圍牆

1. 新建立GameObject ，並重新命名

2. 結構如下，位置擺在座標(0,0,0)即可，將會用腳本另外控制所在位置

3. 在WallManager下掛在新建之腳本WallManager.cs

4. 腳本內容

public class WallManager : MonoBehaviour {

    private BoxCollider2D rightWall;

    private BoxCollider2D leftWall;

    private BoxCollider2D upWall;

    private BoxCollider2D downWall;

    // Use this for initialization

    void Start () {

        ResetWall();

    }

    

     // Update is called once per frame

     void Update () {

         

     }

    void ResetWall()

    {

        // 定義螢幕外的圍牆位置

        rightWall = transform.Find("rightWall").GetComponent<BoxCollider2D>();

        leftWall = transform.Find("leftWall").GetComponent<BoxCollider2D>();

        upWall = transform.Find("upWall").GetComponent<BoxCollider2D>();

        downWall = transform.Find("downWall").GetComponent<BoxCollider2D>();

        Vector3 tempPosition = Camera.main.ScreenToWorldPoint(new Vector2(Screen.width, Screen.height));

        upWall.transform.position = new Vector3(0, tempPosition.y + 0.5f, 0);

        upWall.size = new Vector2(tempPosition.x * 2, 1);

        downWall.transform.position = new Vector3(0, -tempPosition.y - 0.5f, 0);

        downWall.size = new Vector2(tempPosition.x * 2, 1);

        leftWall.transform.position = new Vector3(-tempPosition.x - 0.5f, 0, 0);

        leftWall.size = new Vector2(1, tempPosition.y * 2);

        rightWall.transform.position = new Vector3(tempPosition.x + 0.5f, 0, 0);

        rightWall.size = new Vector2(1, tempPosition.y * 2);

    }

}
