Developing for Perfect World

Hello,i'm a bot developer and a some days ago i've playing perfect world br for fun and i want to build a auto pot bot...
But i've seeing some pw bots and they need to have the pot on the hotkeys,its really a shit.
I've reversing pw client with ollydbg and i found a function with few parameters are : ID of Pot(item),Position in the inventory(its can be from 0 to 31),its really cool...
But how i know the position of the pot on inventory?I've searshing for some inventory structure on memory looking for the id of pot and looking on ollydbg but i don't have success..
I've looking for a mob list structure on memory but not success too...

Ps: I want to discuss all this thing but more important than that are take pw bot developing on a next level.Waiting Replys

EZfix: Have the user input the position in their inventory.
