I don't think your question has enough detail about what you want exactly for anyone to really help you.

#pragma strict
private var screenPoint:Vector3 ;
private var offset:Vector3;
function OnMouseDown() { screenPoint = Camera.main.WorldToScreenPoint(gameObject.transform.position);
offset = gameObject.transform.position - Camera.main.ScreenToWorldPoint(new Vector3(Input.mousePosition.x, Input.mousePosition.y, screenPoint.z));
}
function OnMouseDrag()
{ var curScreenPoint:Vector3 = new Vector3(Input.mousePosition.x, Input.mousePosition.y, screenPoint.z);
var curPosition:Vector3 = Camera.main.ScreenToWorldPoint(curScreenPoint) + offset;
transform.position = curPosition;
}
You Can Use This OK !!!
Looking around I found your code really usefull! But I need to move an object on the x,z axis only, I've tried switching the axis on code but that's not working, how can I modify that code so the object only moves on x,z?
using UnityEngine;
public class DragTest2:$$anonymous$$onoBehaviour
{
private Vector3 screenPoint;
private Vector3 offset;
void On$$anonymous$$ouseDown()
{
screenPoint = Camera.main.WorldToScreenPoint(gameObject.transform.position);
offset = gameObject.transform.position - Camera.main.ScreenToWorldPoint(new Vector3(Input.mousePosition.x, Input.mousePosition.y, screenPoint.z));
}
void On$$anonymous$$ouseDrag()
{
Vector3 curScreenPoint = new Vector3(Input.mousePosition.x, Input.mousePosition.y, screenPoint.z);
Vector3 curPosition = Camera.main.ScreenToWorldPoint(curScreenPoint) + offset;
transform.position = curPosition;
}
}
c# conversion.
Really appreciate that sweet snippet, great work, been head scratching for about a month on this one.
The behavior of the script is a little hard to constrain, but if you want to constrain to a particular axis (2d im guessing from the xz comment)
void On$$anonymous$$ouseDrag()
{
Vector3 curScreenPoint = new Vector3(Input.mousePosition.x, Input.mousePosition.y, screenPoint.z);
Vector3 curPosition = Camera.main.ScreenToWorldPoint(curScreenPoint) + offset;
transform.position = new Vector3(curPosition.x, transform.position.y, curPosition.z);
}
(I wouldn't recommend it though)

Pick the object with Physics.Raycast then move it with Plane.Raycast, the plane being defined by the initial position of the object and the vector initial pos -> Camera.
