Item trigger help!!!

[Tr!KzZ]

i want a trigger specific for an item type:
you need an item in your inventory otherwhise u cant attack, for example a bag of arrows, so the "item" (bag with arrows) has 250 charges but u cant use them just to see. these 250 charges are the arrows, i want that when the hero attack (ranger, or other ranged hero) that for each shot he shoots 1 charge will be removed. for example he buy a bag of arrows, have it in his inventory (250 charges) he shots 15 times, charges left ---> 235. if the charges reach zero the hero cant shot anylonger. and i need a trigger in which only the ranger hero can pick up these back of arrows. thats all ^^ i hope someone could help me.
thx in advance.

You can replace hero unit (with attack) with same hero but not able to attack, when arrow count drops to zero. Then, after buying new arrows, replace him again with attackable hero.

GL!

No you havent read my question correctly :/
I need a explain about item, with which item i should do the "bag of arrows(with 250 charges)" then i want that with every shot of the hero one charges are removed --> hero shots 10 times --> 240 charges left. but u cant klick on this icon to encharge one arrow by klicking. And i need a trigger event which are saying the icon charges reaches 0 then he cant attakc i can do it with lumber ..that works but my item dont work.. u dont see the item, and if u pick it up its not in the inventory.. but i want one in inventory which shows you how much arrows you have left.

When hero shots, use "Item - Set Charges Remaining" action.

Experiment with item properties, IT MUST WORK! Set charges to 250 and, donno (cannot check now), make item unusable, ya know.

:roll:
