One Type of Item in Inventory at a Time

[Isthisnametaken]

How would I make it so that a unit can only be holding 1 "campaign" type item at at a time? I got this far and then I was stumped.

• Offhand
  • Events
    • Unit - A unit Acquires an item
  • Conditions
  • Actions
    • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Conditions
        • (Item-class of (Item being manipulated)) Equal to Campaign
      • Then - Actions
      • Else - Actions

As I understand you correctly you will need this three triggers:

• Get Item
  • Events
    • Unit - A unit Acquires an item
  • Conditions
    • (Item-class of (Item being manipulated)) Equal to Campaign
  • Actions
    • Set ItemCount[(Player number of (Owner of (Hero manipulating item)))] = (ItemCount[(Player number of (Owner of (Hero manipulating item)))] + 1)

• Lose Item
  • Events
    • Unit - A unit Loses an item
  • Conditions
    • (Item-class of (Item being manipulated)) Equal to Campaign
  • Actions
    • Set ItemCount[(Player number of (Owner of (Hero manipulating item)))] = (ItemCount[(Player number of (Owner of (Hero manipulating item)))] - 1)

• Check Item Number
  • Events
    • Unit - A unit Acquires an item
  • Conditions
    • (Item-class of (Item being manipulated)) Equal to Campaign
  • Actions
    • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Conditions
        • ItemCount[(Player number of (Owner of (Hero manipulating item)))] Greater than 1
      • Then - Actions
        • Hero - Drop (Item being manipulated) from (Hero manipulating item)
        • Game - Display to (Player group((Owner of (Hero manipulating item)))) for 5.00 seconds the text: You can take only 1 Item of this Item-Type.
      • Else - Actions

- ItemCount is an integer variable with array.

you can make it with one trigger that works for every player and every hero

just check all 6 slots with integer actions

for each integer from 1 to 6 do
IF
item carried by triggering unit in slot integer A not equal to item being manipulated
item class of item carried my triggering unit in slot Integer A equal to item class of item being manipulated
THAN
drop item being manipulated from triggering unit
ELSE
(do nothing)
