[JASS] TriggerRegisterUnitEvent question

[Eccho]

Okay, so I was unsure about one thing. Let say I do the following:

function Reg takes nothing returns boolean
    call TriggerRegisterUnitEvent(A_trigger, GetFilterUnit(), EVENT_UNIT_DAMAGED)
    return false
endfunction
function IsTest takes nothing returns nothing
    call GroupEnumUnitsInRect(g, WORLD_MAP, Filter(function Reg))
endfunction

What if the unit dies(without decaying)/decays/explodes/removes (and such), will this cause event leaks? I mean, the event will not be used anymore since the unit doesn't exist, therefor it will only take up space in memory?

Is this something to bother about, and/or is there a possible solution?

/regards

I had this dilemma too some weeks ago.
Here is the link to the thread.

function Reg takes nothing returns boolean
    local unit u = GetFilterUnit()
    set trig [a] = CreateTrigger()
    call SetUnitUserData(u,a)
    call TriggerRegisterUnitEvent(trig[a],u,EVENT_UNIT_DAMAGED)
    set a = a + 1
    return false
endfunction
function IsTest takes nothing returns nothing
    call GroupEnumUnitsInRect(g, WORLD_MAP, Filter(function Reg))
endfunction

and when a unit dies

function Dies takes nothing returns nothing
    local unit u = GetTriggerUnit()
    local integer a = GetUnitUserData(u)
    call DestroyTrigger(trig[a])
endfunction

could be better and could be worse


EDIT: Typo

emperor_d3st: yup I have been thinking that way for a long time, to create a trigger for each unit.

Ciebron, yea although I suppose you know DestroyTrigger[a] doesn't exist for real...
It could be better and it could be worse yes, since this is only the half solution to my next problem.

Edit: I found a way through that problem, no need to discuss it =)

Thx to both of you
