Title: drag and drop problem
Post by: i_am_kisly on May 07, 2016, 06:30:18 PM

Hi, I have a question about №11 example. If I replace the container in a grid on the table, when you drag an item he is always in the last cell of the table. This is the first problem.
The second problem is that when I repeat the example with my Asset, the position of movable object does not coincide with the position of the cursor (mouse).
I will appreciate if I prompt solutions to these problems.

Pay close attention to the settings on the grid. Sorting, in particular. By default items are added to the end unless you have sorting set to something. Position-based sorting is what allows for objects to stay where they're dropped.

when I put a check to "clone on drag" I can not move the object to another container.

I still do not understand why the sprite is shifted relative to the cursor. This is also seen in the video.

You need a custom DragDropItem script. Look inside UIDragDropItem.cs, line 320 -- it ignores most of that function is the item is "clone on drag". if you comment out line 320 and 360 it will let you drop items.

Create a custom script derived from UIDragDropItem and overwrite that function, do what you want to do inside.
