Problem with dragging

Hi

I have created a UI canvas with some UI child elements on it. The dimensions of the canvas are 1600 x 800, with 0 in the centre.

I have been trying to learn how to use the IDragHandler interface to drag some UI elements around on the canvas. However, I have a problem that I don't understand. The x y recttransform values of the UI Image to be dragged might start out at -500, -200, for example, but as soon as I try to drag the element, its x y values in the rect transfrom sky rocket to five figures and it disappears off canvas somewhere.

All I'm doing on the dragged object is this:

Code (CSharp):

1. public class ItemDragHandler : MonoBehaviour, IDragHandler
2. {
3.     public void OnDrag(PointerEventData eventData)
4.     {
5.         transform.position = Input.mousePosition;
6.     }
7. }

What am I not doing right?

Cheers

 

Wrong forum. Repost your question here:

I've posted this question three times now. Can you help or not?

 

I'm diving into IUElements at the moment and can't remember all details on Canvas positioning. Perhaps try to manipulate the rectTransform (GetComonent<RectTransform>) instead of the transform and also use the position values stored in your PointerEventData. I remember that you can set an absolute position by setting both anchorMin and anchorMax on rectTransform to the the same position.
