[vJass] Function callback

[~GaLs~]

How do I use method as a function callback such as:

struct ss
  method callback takes nothing returns nothing
    call BJDebugMsg("1")
  endmethod
endstruct

function SomeFunc takes nothing returns nothing
local ss SomeStruct = ss.create()
  call TimerStart(CreateTimer(),1,true, function SomeStruct.callback)
endfunction

i think that you can't as far i know but have you tryed using method instead of function ? I think that you can't but you can have a try

Instead, make callback a static function.

struct ss
    static method callback takes nothing returns nothing //Notice "static"
        call BJDebugMsg("1")
    endmethod
endstruct

function SomeFunc takes nothing returns nothing
    local ss SomeStruct = ss.create()
    call TimerStart(CreateTimer(), 1, true, function ss.callback) //Notice "ss"
endfunction

If you need the callback to be an instance method check vexorians timelib, should be linked from here somewhere. It's in the pastebin of wc3c so it's kinda hard to find without link...

timelib..?
Never heard of it though..

@uber
I think that uber got the answer for me...I havent tried it out though.

Do you mean this?

Well, I have another problem that is similar to this.
How can I do this:

struct ss
group p = CreateGroup()

method Cond takes nothing returns boolean
  return GetUnitState(GetFilterUnit(),UNIT_STATE_LIFE) >0 and IsUnitInGroup(GetFilterUnit(),.p) == false
endmethod

method Act takes nothing returns nothing
  call KillUnit(GetEnumUnit())
  call GroupAddUnit(.p,GetEnumUnit())
endmethod
endstruct

function somefunc takes nothing returns nothing
local ss ii = ss.create()
  call GroupEnumUnitsInRange(ii.p,0,0,200, Condition(function ii.Cond))
  call ForGroup(ii.p,function ii.Act)
endfunction

Whoa, whoa, slow down guys.

Isn't it the other way around?

struct A
    method AMethod takes nothing returns nothing
    // ...
    endmethod
endstruct

function RunMethod takes nothing returns nothing
    local A a = A.create()
    call a.AMethod()
endfunction

And:

struct A
    static method AMethod takes nothing returns nothing
    // ...
    endmethod
endstruct

function RunMethod takes nothing returns nothing
    call A.AMethod()
endfunction

Because .create is a static method and it is called like <struct name>.create(), not <struct instance (var) name>.create().

Btw, you're missing endmethod in Cond method.

What's BJS_DamagedCond supposed to be?

Why would you use ForGroup anyways?

I still don't get Timelib, because there's no explanation on how to use it or what it is anyways. Can someone explain?

>>Because .create is a static method and it is called like <struct name>.create(), not <struct instance (var) name>.create().
Hmm, I think I know this.

>>Btw, you're missing endmethod in Cond method.
Silly mistake caused by fast typing.

>>Why would you use ForGroup anyways?
Because I can't use ForGroupBJ.

@Silvernon
Hmm, you don't get my question.
Saw my method that uses this. ? I wanted method to be used as a ConditionFunc of my group picking...understand?
Well, I can't use static method. As I need to get back the value that is being set in the struct instance.

struct ss
group p = CreateGroup()

method Cond takes nothing returns boolean
  return GetUnitState(GetFilterUnit(),UNIT_STATE_LIFE) >0 and IsUnitInGroup(GetFilterUnit(),.p) == false
endmethod

method Act takes nothing returns nothing
  call KillUnit(GetEnumUnit())
  call GroupAddUnit(.p,GetEnumUnit())
endmethod
endstruct

function somefunc takes nothing returns nothing
local ss ii = ss.create()
  call GroupEnumUnitsInRange(ii.p,0,0,200, Condition(function ii.Cond))
  call ForGroup(ii.p,function ii.Act)
endfunction

Why do you need that condition to be a struct method anyway? The last check is not needed since it doesn't matter if you add a unit to a group twice, the same thing applies to the ss.Act method.

It seems as you are using structs just because you "want" to use them, if it makes the solution more complex then you are wasting time.
