Hi,

is there a chance to find out if an item got looted from the ground or bought in a shop?

I am working with level restrictions.

Example 1:
hero level 1 wants to acquire a level 5 item via shop -> hero level ain't high enough -> remove item from hero and return gold

Example 2:
hero level 1 wants to acquire a dropped level 5 item -> hero level ain't high enough -> item gets dropped and removed due the trigger in example 1. (Instead of just dropping)

How am I solving this problem? It seems like I can't check if the item got dropped or bought in a shop. I know there is a solution because i played RPGs which got level restrictions on items too.

thanks
 
ooo ok mybe ill make a gui friendly version. just keep looking on here if i make one ill post it here for u.

here u go just copy paste and follow instructions on how to install and use in gui.

JASS:
/*
================================ Requirements =================================
    This System does not need any other systems for it to work. 
    
================================ Installing =================================
    Just copy and paste this library to your map and change the values i listed below and you are good to go.
    Create variables in your variable editor. Make a trigger go to edit and convert to custom text.
    then delete everything there and paste this in its place. name the trigger ItemDatabase
    
================================ variables to create =================================
    variable type  |     name
        Integer    |  MERCHANT
        Integer    |  BUYER
        Hashtable  |  itemHash
    
================================ how to use functions / custom scripts =================================
    here is the custom scripts u can copy from here paste and change values u need to
    call GetItemGoldCost( GetItemTypeId( GetManipulatedItem()))                -     this is for getting gold cost
    call GetItemLumberCost( GetItemTypeId( GetManipulatedItem()))              -     this is for getting lumber cost
    call ItemLvlCheck( boolean) true for drop item, false for remove item      -     this is to see if unit is able to use item
    
================================ Explanation =================================
    This system allows you to get the item cost and lumber cost of any item you have picked up.
    It also has an option that allows you to order a unit to drop item if the item lvl is higher than the hero lvl.
    You have 2 options when it comes to this you can either have the unit drop the item or you can remove the item.

================================ Things You need to change =================================
    You do need to change 2 values and create a unit
    The unit must have the abilities Sell Items and Shop Purchase Item. I used the marketplace.
    You have to change MERCHANT to your marketplace and change BUYER to a unit w a backpack.
