Title: Drag & Drop Question
Post by: ahaykal on May 23, 2015, 05:02:37 AM

Hello Nguiers,

I would like to ask a question concerning drag and drop.
My issue is the following:

I have 2 containers/grids that I am moving items between them. Everything is working fine but I am wondering if it is possible to do this:

Right now, when I click and drag I move the sprite and on releasing the object it gets sorted in the grid.
Is it possible to sort it while dragging and not when the dragging ends?
I was wondering if anyone could help me with this matter !

Thank you for your help!

Sure, you can do what you want. Just listen to OnDrag events (or OnDragOver if you want to be more efficient) and call the grid's sorting.

The problem with that is the dragged object isn't reparented, so calling the grid sort isn't working.

You can have a dummy object get created when you start the drag operation, with this dummy object parented to the grid. Adjust its position when you drag and call the grid's Reposition() -- it will act as you expect. Destroy this dummy game object when you stop the drag operation.
