如何禁用鼠標點擊時的對象控制？

Question

當用戶移動鼠標指針然後單擊時，它是x軸對象。對象落在同一鼠標指針位置的地面上。但是當用戶移動指針位置時物體下降也會影響物體下落的位置。我只想讓物體落在用戶點擊的位置，並在落地時不控制物體。 代碼：

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; 
    } 
}

從我的評論Folloup。點擊鼠標後，退出該功能。真的沒有比這更多。

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; 
    } 
}
