I saw the example about the Item Drag(Example 11 - Drag & Drop,Example X - Character), But I can't understand it completely,i'm junior ：）,Could you give a simplify sample about this.or some document or video about it.
if you can give the sample . I hope it would include sth in below:
1. it shows how to drag the item from a item box to another.I don't care the detail about the item. just simplify
2. how to response the some even about it,like when drop,drag and so on, and how to define the box whether or not can be drag item to it .
Temporarily on these ..Thank you so much!!!!
