Today I needed to build shops and merchants for our game. The details and code involved with the current drag and drop inventory system was really complicated yet functioning flawlessly. I really wanted to continue this integration into the merchants that will be scattered all over the game. I found a way to incorporate all of the same features into this shop. I have it designed so various factors are present such as sound, dialogue, icons, portrait, drag and drop and double clicking are all present.
I haven't finalized the look yet as I just built a working prototype but that hard part is done. I'll post a final design at some point.
