c# - 如何禁用鼠标单击时的对象控制？

Question

当用户移动鼠标指针然后单击时，它是 x 轴对象。对象落在同一鼠标指针位置的地面上。但是当物体下落时，如果用户移动指针的位置，它也会影响物体下落的位置。我只希望物体落在用户点击的位置，落在地上时不控制物体。代码:

public class Ball : MonoBehaviour {

    Rigidbody2D body;
    float mousePosInBlocks;

    void Start () {
        body = GetComponent<Rigidbody2D> ();
        body.isKinematic = true;

    }

    void Update () {

        if (Input.GetMouseButtonDown (0)) {

            body.isKinematic = false;
        }

        Vector3 ballPos = new Vector3 (0f, this.transform.position.y, 0f);
        mousePosInBlocks = Camera.main.ScreenToWorldPoint(Input.mousePosition).x;


        //not go outside from border
        ballPos.x = Mathf.Clamp (mousePosInBlocks, -2.40f, 2.40f);

        body.position = ballPos;
    }
}

根据我的评论跟进。鼠标点击出现后退出该功能即可。真的没有比这更多的了。

public class Ball : MonoBehaviour {

    Rigidbody2D body;
    float mousePosInBlocks;
    bool wasDropped = false;

    void Start () {
        body = GetComponent<Rigidbody2D> ();
        body.isKinematic = true;
    }

    void Update () {
        //Don't do anything after the ball is dropped.
        if(wasDropped)
            return;

        if (Input.GetMouseButtonDown (0)) {
            body.isKinematic = false;
            wasDropped = true;
        }

        Vector3 ballPos = new Vector3 (0f, this.transform.position.y, 0f);
        mousePosInBlocks = Camera.main.ScreenToWorldPoint(Input.mousePosition).x;
        //not go outside from border
        ballPos.x = Mathf.Clamp (mousePosInBlocks, -2.40f, 2.40f);

        body.position = ballPos;
    }
}
