Can you detect item destruction

[best_player_88]

Unit attack an item and it dies

can this detected at all?
can you detect item being attacked at least?

Run a periodic timer that checks item life with GetWidgetLife, maybe something like this:

function onUpdate takes nothing returns nothing
    local real life = GetWidgetLife(itm)
    if life < 0.405 then // maybe it should be "<=", I'm not sure
        // Item was destroyed
            // ...
            // ...
            // ...

    elseif life < BlzGetItemIntegerField(itm, ITEM_IF_MAX_HIT_POINTS)
        // Item was damaged
            // ...
            // ...
            // ...
    endif
endfunction

call TimerStart(updateTimer, 0.1, true, function onUpdate)

If there are multiple items, you need to add them to a list and iterate through it.

Items are widgets, so you should be able to use this widget event:
constant widgetevent EVENT_WIDGET_DEATH = ConvertWidgetEvent(89)
But... there's no TriggerRegisterWidgetEvent... wtf Blizzard?

Luckily, there is also this native:
native TriggerRegisterDeathEvent takes trigger whichTrigger, widget whichWidget returns event
