A spell that creates "x" number of "y" but only when "l" number of "z" is present

[Turnip]

I've been trying to creating a trigger that doesn't leak and works efficiently, but so far, I have been unsuccessful.

Example: There is a doctor hero. He has a spell that creates x number of bandages depending on level (level 1 - one bandage, level 2 - two bandages, etc...), but requires y number of scraps of linen before it can be created. However, this linen stacks. So, I only want to remove as much linen as required and not all of it.


Any ideas on how to do it?

There's a trigger function that does: 'set item number of charges'.
So, if your hero uses 'Create medpack' ability:

event
A unit starts the effects of an ability

cond
Abilitiy being cast = *Your_Ability*
(Triggering unit) has item of type *Your_Linen_Item*

Actions
set medpack_point = Position of (Triggering unit)
 Loop (for each Integer A from 1 to (Level of *Your_Ability* of (Triggering unit)) do Actions
 If (Number of charges remaining for *Your_Linen_Item* carried by (Triggering unit) is equal to 0 then
  [COLOR="Red"]Do Nothing[/COLOR]
  else
   set number of charges for *Your_Linen_Item* carried by (Triggering unit) = (current number of charges - 1)
   Create 1 *Bandage* at medpackpoint
Custom script - call RemoveLocation(udg_medpack_point)

Should work.
I don't have WE open, so the triggers aren't perfect, but I bet you get the picture.

EDIT: Notice, the 'Do Nothing' function is not necessary for your trigger. I just put it there for you to get the idea.

Thank you so much - I am very grateful.

Another quick question: Is there a trigger to check if an item has 0 charges, so I can remove it from the hero if it does?

if an item has 0 charges it disapears

If only it were that simple.

You realize I'm using GUI here, right?

Convert to Bandage
    Events
        Unit - A unit Starts the effect of an ability
    Conditions
        (Ability being cast) Equal to Animate Dead
    Actions
        For each (Integer A) from 1 to 6, do (Actions)
            Loop - Actions
                If (All Conditions are True) then do (Then Actions) else do (Else Actions)
                    If - Conditions
                        (Item carried by (Casting unit) in slot (Integer A)) Equal to (Item carried by (Casting unit) of type Tome of Experience)
                    Then - Actions
                        Hero - Create Tome of Experience and give it to (Casting unit)
                        If (All Conditions are True) then do (Then Actions) else do (Else Actions)
                            If - Conditions
                                (Charges remaining in (Item carried by (Casting unit) of type Tome of Experience)) Equal to 0
                            Then - Actions
                                Item - Remove (Item carried by (Casting unit) of type Tome of Experience)
                            Else - Actions
                                Item - Set charges remaining in (Last created item) to ((Charges remaining in (Item carried by (Casting unit) of type Tome of Experience)) - 1)
                    Else - Actions

Maybe that would work, assuming you change the items being carried?

Thanks, however I need the item to be removed even if a spell is not initiated - for example when the item is simply consumed. It doesn't dissapear but instead just goes to 0 charges where it can be used over and over again.

Is this possibly because of the item I based it off of?

Go to your item, and tick "Perishable - True."
