A test map is attached.
A system that prevents a unit from holding more than 1 of the same item at a time.

The Event can also be related to an Event where the unit bought an item from the shop, not just collect from ground, okay ?
So don't worry about it, works for both collect item on ground and buys an item from shop Event

Here is a simple JASS snippet for you ^.^

//===========================================================================
// I made a snippet for you to use ^.^
//
// [1] Backup your map first!
//
// [2] Make a trigger in your map and convert it to custom text and clear its
// contents.
//
// [3] Copy paste everything in here and paste it inside the new trigger
//
// [4] Rename it as "Item Limiter"
//
// [5] And your ready to go!
//===========================================================================

function Display_Duration takes nothing returns real
    return 12.00 // <==this is how long the message will display itself
endfunction

function Message takes nothing returns string
    return "|cffff0000WARNING!: You can only have one weapon of the same type!" // <==this is the error message shown
    //when someone violates the item limit
endfunction

function Maximum_Item_Limit takes nothing returns integer
     return 1 // <== this is the maximum item limit
endfunction

function Item_Limiter takes nothing returns boolean
    local integer nloops       =0
    local integer nloopsmax    =5
    local integer ncounter     =0
    local unit    ItemOwner    =GetManipulatingUnit()
    local item    ItemAcquired =GetManipulatedItem()
    local item    ItemInSlot
    local integer ItemTypeId   =GetItemTypeId(ItemAcquired)
    
    loop
        exitwhen nloops>nloopsmax
        set ItemInSlot=UnitItemInSlot(ItemOwner,nloops)
        if(ItemInSlot!=null and GetItemTypeId(ItemInSlot)==ItemTypeId)then
            set ncounter=ncounter+1
        endif
        set nloops=nloops+1
    endloop
    
    if(ncounter>Maximum_Item_Limit())then
        call UnitRemoveItem(ItemOwner,ItemAcquired)
        DisplayTimedTextToPlayer(GetOwningPlayer(ItemOwner),0,0,Display_Duration(),Message())
    endif
    set ItemOwner=null
    set ItemInSlot=null
    return false
endfunction
//===========================================================================
function InitTrig_Item_Limiter takes nothing returns nothing
    local trigger Item_Limiter_Trg = CreateTrigger()
    call TriggerRegisterAnyUnitEventBJ(Item_Limiter_Trg,EVENT_PLAYER_UNIT_PICKUP_ITEM )
    call TriggerAddCondition(Item_Limiter_Trg,Condition(function Item_Limiter) )
endfunction

You can now configure the warning message, its display time, and the maximum item limit.

Alain.Mark, use DisplayTimedTextToPlayer() for fake error messages; the BJDebugMsg() displays messages for an unlimited amount of time.

 

[-Kobas-]

Floating text is even better idea, this way you can make it look like unit say message

 

[Alain.Mark]

Sorry for the function calls guys but I do not know if valeman knows vJASS.

@Kobas can you edit the code se he can have options?

 

[-Kobas-]

S@Kobas can you edit the code se he can have options?

What code, and what options?

 

[Bribe]

Alain.Mark, use DisplayTimedTextToPlayer() for fake error messages; the BJDebugMsg() displays messages for an unlimited amount of time.

Yeah those one minute time periods take forever.

 

[valeman2]

Give me the simplest option to Limit 1 Item per player do it. (Without downloading)

 

[thekebecer]

Use what Kobas said, it's the better way to do what you want.

 

[defskull]

1 item per player or 1 item per unit ???
Gotta explain it clearly dude...

 

[Alain.Mark]

Yeah those one minute time periods take forever.

==>I edited it already so he can configure the time.

What code, and what options?

==> I mean the snippet i made so he can choose between DisplayTimedTextToPlayer() or use Floating texts.

==> But its pointless anyway since he already might have a solution.
