"If unit has this item then do this" question

I'm making a trigger that does this,

There's 2 items, item 1 and item 2.

When a unit tries to pick up item1, the trigger will check to see if Item 2 is in the unit's inventory. If the unit has Item 2, then the unit can't pick up Item 1.

Is there a way to do this?
 
Don't have WE open right now, buy something like this should work:

Event -
unit aquires item

Condition -
Boolean: triggering item = item type: item 2
- unit has item of type item 1 in inventory

Action -
order unit to drop item 2

If that doesn't work, just browse through the item-related events, conditions and actions and you're bound to find an easy solution.
 
If hero has item type of itemA and item being manipualted equal to itemB then drop item being manipulated.

And make another but switch the itema and b around.
 
I got this so far, but it's not workin.

Code: 
Events
    Unit - A unit Acquires an item
Actions
    If (All Conditions are True) then do (Then Actions) else do (Else Actions)
        If - Conditions
            (Item carried by (Triggering unit) of type Assult Riffle) Equal to (Item being manipulated)
        Then - Actions
            Hero - Drop (Item being manipulated) from (Triggering unit)
        Else - Actions

I also tried:
Code: 
Actions
    If (All Conditions are True) then do (Then Actions) else do (Else Actions)
        If - Conditions
            (Item carried by (Triggering unit) of type Assult Riffle) Equal to (Item carried by (Triggering unit) of type (Item-type of (Item being manipulated)))
        Then - Actions
            Hero - Drop (Item being manipulated) from (Triggering unit)
        Else - Actions

What am I doing wrong?
 
Code: 
Event
    Unit - A unit Acquires an Item
Conditions
    (Item type of (Item being manipulated)) Equal to Assault Rifle
Actions
    Hero - Drop (Item being manipulated) from (Hero manipulating item)

I dun' have my WE open so I'll edit this..
 
Ok, I tried this. When the hero picks up the Assault Rifle item, it drops right away.

I still can't get this to compare the item in the unit's inventory to the item being picked up. Where's the trigger that checks the hero's inventory?

This

Add condition that Or (any conditions are true) and put this..
(Item carried by (Hero manipulating item) in slot [num]) Equal to (Item of type (ITEM 2)

Code: 
Or (Any Conditions) are true
    (Item carried by (Hero manipulating item) in slot 1) Equal to (Item of type (ITEM 2)
    (Item carried by (Hero manipulating item) in slot 2) Equal to (Item of type (ITEM 2)
 ......
 
Or then simply loop through the whole inventory, making the progress much easier.

Code: 
Trigger01
    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-type of (Item being manipulated)) Equal to <item1 type>
            Then - 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-type of (Item carried by (Triggering unit) in slot (Integer A))) Equal to <item2 type>
                            Then - Actions
                                Hero - Drop (Item being manipulated) from (Triggering unit)
                            Else - Actions
            Else - Actions
                If (All Conditions are True) then do (Then Actions) else do (Else Actions)
                    If - Conditions
                        (Item-type of (Item being manipulated)) Equal to <item2 type>
                    Then - 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)

                                    Then - Actions
                                        Hero - Drop (Item being manipulated) from (Triggering unit)

Never knew GUI had one.

        If (All Conditions are True) then do (Then Actions) else do (Else Actions)

                                Hero - Drop (Item being manipulated) from (Triggering unit)

Actually, on second though, you can do this...
Code: 
Trigger01
    Events
        Unit - A unit Acquires an item
    Conditions
    Actions
        If (All Conditions are True) then do (Then Actions) else do (Else Actions)
            If - Conditions
                ((Triggering unit) has an item of type <item1 type>) Equal to True
                ((Triggering unit) has an item of type <item2 type>) Equal to True
            Then - Actions
                Hero - Drop (Item being manipulated) from (Triggering unit)
            Else - Actions

That should work, probably the shortest code possible, either that or i'm ub3r tired.
 
Still you have to check if the acquired item is item type1 or item type2. What if the unit picks restoriation potion?
 
I cant find this, "((Triggering unit) has an item of type <item2 type>) Equal to True".

I looked at the item triggers and and unit triggers. Then closest thing I found was "(Item carried by (Triggering unit) of type Assult Riffle) Equal to (Item being manipulated)"


btw, I'm using the original world editor and I didn't add advanced triggers or anything.

That leaks.
If we say, that I got both item1 and item2, and I pick up item3, then it will drop item3. See?
 
> I can't find this

It's hidden under Boolean, Hero - Hero has item of type.

Yes, it works on anything with an inventory, not just Heroes.
 
Nice, it works. Thx alot.

I modified it for 4 weapons, Assult Riffle, Shotgun, Minigun, and Heavy Support Riffle.

Code: 
Events
    Unit - A unit Acquires an item

Actions
    -------- assult rifle --------
    If (All Conditions are True) then do (Then Actions) else do (Else Actions)
        If - Conditions
            ((Triggering unit) has an item of type Assult Riffle) Equal to True
            ((Triggering unit) has an item of type Shotgun) Equal to True
        Then - Actions
            Hero - Drop (Item being manipulated) from (Triggering unit)
        Else - Actions
    If (All Conditions are True) then do (Then Actions) else do (Else Actions)
        If - Conditions
            ((Triggering unit) has an item of type Assult Riffle) Equal to True
            ((Triggering unit) has an item of type Minigun) Equal to True
        Then - Actions
            Hero - Drop (Item being manipulated) from (Triggering unit)
        Else - Actions
    If (All Conditions are True) then do (Then Actions) else do (Else Actions)
        If - Conditions
            ((Triggering unit) has an item of type Assult Riffle) Equal to True
            ((Triggering unit) has an item of type Heavy Support Riffle) Equal to True
        Then - Actions
            Hero - Drop (Item being manipulated) from (Triggering unit)
        Else - Actions
    -------- heavy --------
    If (All Conditions are True) then do (Then Actions) else do (Else Actions)
        If - Conditions
            ((Triggering unit) has an item of type Heavy Support Riffle) Equal to True
            ((Triggering unit) has an item of type Shotgun) Equal to True
        Then - Actions
            Hero - Drop (Item being manipulated) from (Triggering unit)
        Else - Actions
    If (All Conditions are True) then do (Then Actions) else do (Else Actions)
        If - Conditions
            ((Triggering unit) has an item of type Heavy Support Riffle) Equal to True
            ((Triggering unit) has an item of type Minigun) Equal to True
        Then - Actions
            Hero - Drop (Item being manipulated) from (Triggering unit)
        Else - Actions
    -------- shotgun --------
    If (All Conditions are True) then do (Then Actions) else do (Else Actions)
        If - Conditions
            ((Triggering unit) has an item of type Shotgun) Equal to True
            ((Triggering unit) has an item of type Minigun) Equal to True
        Then - Actions
            Hero - Drop (Item being manipulated) from (Triggering unit)
        Else - Actions


But now there's a new problem. I got 2 assult riffles in the map. I need to make it so a unit can't pickup both of them.

I tried this:
Code: 
    If (All Conditions are True) then do (Then Actions) else do (Else Actions)
        If - Conditions
            ((Triggering unit) has an item of type Assult Riffle) Equal to True
            ((Triggering unit) has an item of type Assult Riffle) Equal to True
        Then - Actions
            Hero - Drop (Item being manipulated) from (Triggering unit)
        Else - Actions

But right when the unit picks up the item, it drops. I cant figure out a way around this. Any ideas?

No, you shouldn't even be able to have item2 in the first place, and that's not even what a leak is.

Here's my map, it has those systems and everything...
