Item-Type, Inventory, and Hero Level Help Needed

I'm trying to make a new rpg, that is mostly like Master Crafters. I need help with...
-Inventory system... like that where when you pick up an item it will be placed in a designated area...

-Item-Type... my map has alot of weapons... so left-handed... some right... i need it to be that if my unit picks up a left handed weapon, then picks up another one, the latest one picked up will be put into inventory.

-Hero Level... I know this is probally gonna sound real nooby but, how can i make a heroes max level like 100...

The hero level can be changed at:
Advanced --> Gameplay Constants --> Hero Maximum Level - (Your value here)

Inventory system... this should cover both it and type at the same time (just give credit to Blade.dk)

ok new problem... i cant do jass for my own life... mabye one of you could help me do jass... i will definatly give you credit...

I can't JASS for anything. Look for UMSWE (Ultra Mega Super World Editor)... it's a tool somewhere... or JASSCraft or something...

*Toadcop - Edited to fix.

well then do you know how to make it that if i pick up a left handed item then i pick up another one(left handed) the last one i picked up goes to a region

Use Map Settings World Editor ;) UMS was a category for maps in the origional SC.

Also, WE Unlimited dwarfs UMSWE. And, WE Unlimited still sucks compared to learning JASS. odds are, if you wanna mod games in the future (diffrent games) or if you want a job in the tech industry, understanding programing in general will be verry benifitial. (JASS is also a piss easy language to start with)
