How can I detect more than one item of the same type in region?

How can I detect more than one item of the same type in a region and the charges remaining in each?

It is almost impossible to help you with that few information.
I would say, store the information in a hashtable using the handle id as parent key, but you should simply explain more.

As said above you haven't exactly stated what you want to do...

However, you can do a "pick all items in region" function, then add a condition that the item is the specific item type. If you an integer variable you could then add the number of charges to this variable, depends how/what you want to count though

I'm making a crafting system that uses itens on the ground to create refined itens. Example: to make a sharp stones, you would need two stones (with 1 charge each) on the grund or one stone with 2 charges (two stones stacked together). After the crafting is done, if the stone has no charges left it is then removed. After that process, a Sharp Stone item is created on the ground. I'm not sure if you can compreend my objective perfectly.

Do, what Karzama said: Pick all items in region.

You can check for the item type as well for the item charges (integer comparisson).

I would check first for all stones in your region/range, if there is a stone with >=2 charges for your example. If there is reduce charges (if 0 remove stone) and create sharp stone. If there is no item with >=2 charges, then do a second loop, which searches for several items of type stone.

I think this is your question? Just save the first item of type stone in a temp variable ot type item called Stone_1. and ask before storing a stone into it, if it is null or if there is already a stone saved. If there was one saved, you obviously found a second stone and can combine them. Dont forget to set Stone_1 = null (no item) after the search algorythm.

this is what I've got so far, but I'm not sure of what I'm doing:

• Pedra Afiada
  • Events
    • Unit - A unit Starts the effect of an ability
  • Conditions
    • (Ability being cast) Equal to Sharp Stone (Crafting)
  • Actions
    • Item - Pick every item in (Region centered at (Position of (Triggering unit)) with size (500.00, 500.00)) and do (Actions)
      • Loop - Actions
        • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
          • If - Conditions
            • (Item-type of (Picked item)) Equal to Stone
          • Then - Actions
            • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
              • If - Conditions
                • (Charges remaining in (Picked item)) Greater than or equal to 2
              • Then - Actions
                • Item - Set charges remaining in (Picked item) to ((Charges remaining in (Picked item)) - 2)
                • Item - Create Sharp Stone at (Position of (Picked item))
                • Item - Set charges remaining in (Last created item) to 1
                • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
                  • If - Conditions
                    • (Charges remaining in (Picked item)) Equal to 0
                  • Then - Actions
                    • Item - Remove (Picked item)
                  • Else - Actions
              • Else - Actions
                • Set Stone_1 = (Picked item)
                • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
                  • If - Conditions
                    • Stone_1 Equal to No item
                  • Then - Actions
                    • Set Stone_1 = (Picked item)
                  • Else - Actions
          • Else - Actions

I would use 2 loops: I inserted a boolean Found_Stone for the search in to your example.

• Pedra Afiada
  • Events
    • Unit - A unit Starts the effect of an ability
  • Conditions
    • (Ability being cast) Equal to Sharp Stone (Crafting)
  • Actions
    • Set Found_Stone = false
    • Item - Pick every item in (Region centered at (Position of (Triggering unit)) with size (500.00, 500.00)) and do (Actions)
      • Loop - Actions
        • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
          • If - Conditions
            • (Item-type of (Picked item)) Equal to Stone
          • Then - Actions
            • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
              • If - Conditions
                • (Charges remaining in (Picked item)) Greater than or equal to 2
              • Then - Actions
                • Item - Set charges remaining in (Picked item) to ((Charges remaining in (Picked item)) - 2)
                • Item - Create Sharp Stone at (Position of (Picked item))
                • Item - Set charges remaining in (Last created item) to 1
                • Set Found_Stone = true
                • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
                  • If - Conditions
                    • (Charges remaining in (Picked item)) Equal to 0
                  • Then - Actions
                    • Item - Remove (Picked item)
                  • Else - Actions
              • Else - Actions
• If (All Conditions are True) then do (Then Actions) else do (Else Actions)
  • If - Conditions
    • Found_Stone = false
  • Then - Actions
  • Set Stone_1 = no item
  • Item - Pick every item in (Region centered at (Position of (Triggering unit)) with size (500.00, 500.00)) and do (Actions)
    • Loop - Actions
      • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
        • If - Conditions
          • (Item-type of (Picked item)) Equal to Stone
        • Then - Actions
          • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
            • If - Conditions
              • Stone_Found == False
            • Then - Actions
            • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
              • If - Conditions
                • Stone_1 == no item
              • Then - Actions
                • Set Stone_1 = Picked Item
              • Else - Actions
                • Item - Remove (Picked item)
                • Item - Remove (Stone_1)
                • Item - Create Sharp Stone at (Position of (Picked item))
                • Item - Set charges remaining in (Last created item) to 1
                • Set Found_Stone = true
• Set Found_Stone = false
• Set Stone_1 = no item

of course it would be possible and nicer to have only one loop, but I have a hard time with these giant walls of GUI code. But it works like this. You could optimize it later to have one loop doing this
