I've purchased several different inventory systems and none of them are good enough. None of them are both fully featured and compatible with NGUI 3.7. I have decided that if you want it done right, you have to hire someone to help you figure out how to do it yourself xD
What I'm working on:
Options menu
Crafting Item ability
Drag and drop items
Weapons Hotbar
Draggable windows
Stacking items
Tetris-style items in inventory
Wearables
Weapons
Crafting supplies and tools
Chat notifications
Items visible on 3rd person character screen
Character rotation in menu
I know NGUI has the power to accomplish all this, I've seen everything here done before, but never all in the same system, and nothing close to convenient. I have scraps of code from all the different systems I own, I'm not proficient enough in either NGUI or C# to be able to combine them seamlessly.
