vJass question

I have a periodical timer, when I change the struct, do I need to attach it to the timer again?

JASS:

struct Data
    integer i = 0
endstruct

function Example_Execute takes nothing returns nothing
    local timer t = GetExpiredTimer()
    local Data d = Data(GetAttachedInt(t, "d"))
    // ...
    set d.i = d.i + 1
    call AttachInt(t, "d", d)
endfunction

function Example takes nothing returns nothing
    local timer t = CreateTimer()
    local Data d = Data.create()
    // ...
    call AttachInt(t, "d", d)
    call TimerStart(t, 0.04, true, function Example_Execute)
    // ...
endfunction

I hope my question is clear.

PipeDream	You do not need to reattach it to the timer.

Silvenon	Well, that's loud and clear Now I feel like an idiot, I've been reattaching it every time, if only I had known... Thanks for the help

That is because a struct variable is just a normal integer, its members are global variable arrays. You change the members but the struct variable isn't, so you don't need to reattach it.

JASS:

struct structdata
 unit u

function blah takes nothing reutrns nothing
local structdata d = structdata.create() //In this case, the struct will be == 1 bec it's the first instance.
 set d.u = GetTriggerUnit()
endfunction
