I need a little idea about rpg inventory gui system. I have an inventory system in my game which works like most 2D browser based mmorpg. Single item occipies single slot. What I want to do is, make it more like diablo inventory system. Different items occupies different slot(s). I need some idea how to approach? I only need to know how do I detect the slot size of an item over inventory slots. My inventory right now is more like the left one, I want to convert it to right one (Diablo).
Thanks in advance
