How do i make hero only able to use 1 of an item?

[Shanghai]

i gona have like 5 diffrent items. how do i make so that the hero only can use one item of this item at time.

Its because i have diff wepaons on those items.

And note im using other items to. so i need good solution.

For example.

Sword
Axe
Hammer
Club
Mace

It wont look good if the hero have sword + axe + hammer + club + mace at same time.

How can i solve this?

Or is there any other good solution for this?

An easy and efficient way is to use Item levels.
Every item has "Stats - Level" which doesn't really serve anything important for the item itself. However you may use it as a category.
For example -> weapons will be items with level 1, armor will have level 2, potions level 3, etc.

Then when hero picks up an item, you check if he doesn't already have an item with same level, if yes, make him drop picked item.


Edit
Something like this:

Click

• Untitled Trigger 001
  • Events
    • Unit - A unit Acquires an item
  • Conditions
  • Actions
    • Set unit_var = (Triggering unit)
    • Set item_var = (Item being manipulated)
    • For each (Integer loopInt) from 1 to 6, do (Actions)
      • Loop - Actions
        • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
          • If - Conditions
            • (Item level of (Item carried by unit_var in slot loopInt)) Equal to (Item level of item_var)
            • (Item carried by unit_var in slot loopInt) Not equal to item_var
          • Then - Actions
            • Hero - Drop item_var from unit_var
          • Else - Actions
    • Set unit_var = No unit
    • Set item_var = No item

Just one problem with this. I have 6 diffrent weapons. And then i prob gona use 30 normal items. So what hapens if the normal items r set to level 0. Some of the normal items i can have more then 1 item of.

Nichilus is right.
If you want to do this simply, you'll have to reserve a level for each type of equipment.
The item level doesn't really interfere in the game besides.

i know this is best solution. But the thing is that i use... 6 weapons and like mybe 30 normal items. and some of the normal items you can have more then 1 of hmm

You can have thousands of item levels without any trouble.

Other solution could be to use unit classification. For example put all weapons in "Campagne" classificatopn, and later check if unit has already an item of classification "campange".
