[Solved] How to limit items one unit can have?

[louie999]

I'm making a shooter kind of map and i want to make a unit only have 1 type of item:
Example: A unit can only have 1 Potion of healing item at once and cant have 2.
How do i do that ? do i have to create a trigger for that ?

Event: Unit aquires item
Condition: Check for your itemType
Actions:
Use the ForEachInteger function to loop from 1-6:
Set tmpItem = Item Carried By TriggeringUnit in Slot[LoopIndex]
Then check if ItemTypeOf(tmpItem) == yourItemType AND tmpItem != ItemBeingManipulated.
If both are true, then drop ItemBeingManipulated from unit.

tmpItem is a item variable

Like this ?

• Item Limit
  • Events
    • Unit - A unit Acquires an item
  • Conditions
    • (Item-type of (Item being manipulated)) Equal to Health Artifact(+50)
  • Actions
    • For each (Integer A) from 1 to 6, do (Actions)
      • Loop - Actions
        • Set tmpitem = (Item carried by (Triggering unit) in slot (Integer A))
    • Set tmpitem = (Item being manipulated)
    • Unit - Order (Triggering unit) to drop tmpitem at (Position of (Triggering unit))

No. You have to put an IfThenElse into your loop, after you Set your tempItem.
Add the two conditions I mentioned in my post before.
In Then - Actions part you order unit to drop item. Finished.

I don't know if i did this right:

• Item Limit
  • Events
    • Unit - A unit Acquires an item
  • Conditions
  • Actions
    • Set tempitem = (Item carried by (Triggering unit) in slot (Integer A))
    • Set tempitem = (Item being manipulated)
    • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Conditions
        • (Item-type of (Item carried by (Triggering unit) in slot 1)) Equal to Health Artifact(+50)
        • (Number of items carried by (Triggering unit)) Equal to 1
        • tempitem Equal to (Item being manipulated)
        • tempitem Equal to (Item carried by (Triggering unit) in slot 1)
      • Then - Actions
        • For each (Integer A) from 1 to 6, do (Actions)
          • Loop - Actions
            • Unit - Order (Triggering unit) to drop tempitem at (Position of (Triggering unit))
      • Else - Actions

No, look. Like this:

• Events
  • Unit - A Unit quires Item
• Conditions
  • (Item-type of (Item being manipulated)) Equal to Health Artifact(+50)
• Actions
  • Set u = TriggeringUnit
  • For each i from 1 to 6, do (Actions)
    • Set item = (Item carried by (u) in slot (i))
    • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Conditions
        • ItemType of item Equals Health Artifact(+50)
        • item Not Equals ItemBeingManipulated
      • Then - Actions
        • Hero - Drop ItemBeingManipulated for u
      • Else - Actions

u is a unit type variable
i is integer variable, I use LoopWithIntegerVariable instead of LoopWithIntegerA/B

Now i get it.Thank you very much
