Drag and throw object in 3D

Hi guys, I need help with small task. I need to touch the screen, drag object and then throw it out. You can see what I need here at 3:13 DRAG PLAYING CARD - VIDEO

At the moment I can touch object and move throught screen but still few problems remaining:

1. throw it if touchPhase.Ended in proper direction and speed

2. rotate object during moving

If you have any ideas, please let me know, because I am out of ideas :)

• know should't be there GetMouseButton(0), but it is just test version in laptop and I'll change it later. And sorry for grammar ;)

  using UnityEngine; using System.Collections;

  public class MainScript : MonoBehaviour { private float dist; private Transform toDrag; private bool dragging = false; private Vector3 offset; private Vector3 v3;

     void Update() {
                   if (Input.GetMouseButtonDown (0)) {
                           RaycastHit hit;
                           Ray ray = Camera.main.ScreenPointToRay (Input.mousePosition);
                           if (Physics.Raycast (ray, out hit)) {
                                   if (hit.transform.gameObject == GameObject.FindGameObjectWithTag ("card")) {
                                           toDrag = hit.transform;
                                           dist = hit.transform.position.y - Camera.main.transform.position.y;
                                           v3 = new Vector3 (-Input.mousePosition.x, -Input.mousePosition.y, dist);
                                           v3 = Camera.main.ScreenToWorldPoint (v3);
                                           offset = toDrag.position - v3;
                                           dragging = true;
                                   }
                           }
   
                   }
           if(Input.GetMouseButton(0)){
                   if (dragging) {
                           v3 = new Vector3 (-Input.mousePosition.x, -Input.mousePosition.y, dist);
                           v3 = Camera.main.ScreenToWorldPoint (v3);
                           toDrag.position = v3 + offset;
   
                   }
           }
   
           if (Input.GetMouseButtonUp (0)) {
               dragging = false;
   
           }
       
           }
