Unity 2D：如何与屏幕侧面碰撞

Question

我目前正在为 Android 开发 2D 游戏。我的场景中有一个玩家，如果用户倾斜他的设备，玩家对象就会在地面上移动。但他只是从左侧和右侧的屏幕中移出。我试图做一堵“墙”，但没有成功。在我的玩家游戏对象中有一个边缘碰撞器。现在我的问题是：我的玩家游戏对象如何与屏幕的一侧发生碰撞？

这是我的代码：

public GameObject player;
    
    
    // Use this for initialization
    void Start () {
        
    }
    
    // Update is called once per frame
    void Update () {
        Vector3 dir = Vector3.zero;
        dir.y = Input.acceleration.x;

        player.transform.Translate(new Vector2(dir.y, 0) * Time.deltaTime * 2000f);  

    }

非常感谢！:)

图 1 是我的墙，图 2 是我的播放器。

我试图用屏幕一侧的墙来解决它。这些是图片

解决了

解决方案代码：

Vector3 position = player.transform.position;
        translation = Input.acceleration.x * movementSpeed * 50f;

        if (player.transform.position.x + translation < LeftlimitScreen)
        {
            position.x = -LeftlimitScreen;
        } 
        else if(transform.position.x + translation > RightlimitScreen)
        {
            position.x = RightlimitScreen;
        }
        else
        {
            position.x += translation;
            player.transform.position = position;
        }

这段代码对我有用！:)

这将在屏幕周围生成边缘碰撞器（对于 2d）：

void GenerateCollidersAcrossScreen()
    {
     Vector2 lDCorner = camera.ViewportToWorldPoint(new Vector3(0, 0f, camera.nearClipPlane));
     Vector2 rUCorner = camera.ViewportToWorldPoint(new Vector3(1f, 1f, camera.nearClipPlane));
     Vector2[] colliderpoints;

    EdgeCollider2D upperEdge = new GameObject("upperEdge").AddComponent<EdgeCollider2D>();
    colliderpoints = upperEdge.points;
    colliderpoints[0] = new Vector2(lDCorner.x, rUCorner.y);
    colliderpoints[1] = new Vector2(rUCorner.x, rUCorner.y);
    upperEdge.points = colliderpoints;

    EdgeCollider2D lowerEdge = new GameObject("lowerEdge").AddComponent<EdgeCollider2D>();
    colliderpoints = lowerEdge.points;
    colliderpoints[0] = new Vector2(lDCorner.x, lDCorner.y);
    colliderpoints[1] = new Vector2(rUCorner.x, lDCorner.y);
    lowerEdge.points = colliderpoints;

    EdgeCollider2D leftEdge = new GameObject("leftEdge").AddComponent<EdgeCollider2D>();
    colliderpoints = leftEdge.points;
    colliderpoints[0] = new Vector2(lDCorner.x, lDCorner.y);
    colliderpoints[1] = new Vector2(lDCorner.x, rUCorner.y);
    leftEdge.points = colliderpoints;

    EdgeCollider2D rightEdge = new GameObject("rightEdge").AddComponent<EdgeCollider2D>();

    colliderpoints = rightEdge.points;
    colliderpoints[0] = new Vector2(rUCorner.x, rUCorner.y);
    colliderpoints[1] = new Vector2(rUCorner.x, lDCorner.y);
    rightEdge.points = colliderpoints;
}
