Title: Drag and Drop problem
Post by: urban on April 19, 2014, 08:26:24 AM

HI,

I have created a inventory system using NGUI but i have a problem while dragging the item, the sprite doesnt not keep to the center of the mouse curser.

Here is a link to my script

the code for the inventory works fine.

I do not use the uidragroot as that causes more problems
Here is a screen shot of the problem

Please could you help.

You are setting "mTrans.localPosition = Input.mousePosition;" -- This is wrong. Input.mousePosition is in screen coordinates. Transform's localPosition is in local coordinates -- relative to the parent. You need to convert screen to world, then convert world to local using standard math functions (camera.ScreenToWorldPoint, transform.parent.InverseTransformPoint)
