Attaching Struct In a Callback?

[MasterRofl]

How do I make it so that I can use the struct in the callback function?

library NetTrap initializer Init uses ABC

private struct Net
    unit DyingUnit
    group TrapGroup
    location TrapLocation
        method onDestroy takes nothing returns nothing
            set.TrapGroup = null
            set.TrapLocation = null
        endmethod
endstruct

private function Callback takes nothing returns nothing
    local unit NetDummy = CreateUnitAtLoc( GetOwningPlayer(n.DyingUnit), GetUnitLoc(GetEnumUnit()), 0 )
    call UnitAddAbility( NetDummy, 'A01V' )
    call SetUnitAbilityLevel( NetDummy, 'A01V', GetUnitAbilityLevel( udg_JL_Caster, 'A03O' ))
    call IssueTargetOrderById( NetDummy, 'A01V', GetEnumUnit())
    call RemoveUnit( NetDummy )
endfunction

private function Actions takes nothing returns nothing
    local Net n = Net.create()
    set n.TrapLocation = GetUnitLoc(GetDyingUnit())
    set n.TrapGroup = GetUnitsInRangeOfLocMatching( 200., n.TrapLocation, null )
    set n.DyingUnit = GetDyingUnit()
    call ForGroup( n.TrapGroup, function Callback )
    call n.destroy()
endfunction

private function Conds takes nothing returns boolean
    return GetDyingUnit() == 'n00T'
endfunction

private function Init takes nothing returns nothing
    local trigger t = CreateTrigger()
    call TriggerRegisterAnyUnitEventBJ(t, EVENT_UNIT_DEATH)
    call TriggerAddCondition(t, Condition( function Conds ))
    call TriggerAddAction(t, function Actions)
    set t = null
endfunction

endlibrary

Struct Attachment Systems:

ABC by Cohadar

Edit:
Didn't see that

Struct Attachment Systems:

If you look closely he's using ABC system I think he wants to know what is the command.. which is:

SetTimerStructA(timer, struct)

 

[MasterRofl]

Well, what I have there is a callback for "ForGroup," and there's no timer in that right? Do I use SetTriggerStruct?

I can't think of any attachment system that could retrieve the struct in a ForGroup callback. Probably mainly because there isn't much to attach to.
You could set the struct to a global variable or loop through the group using the FirstOfGroup thingy.

Easiest way is probably to do global struct i.e.

private struct Net
...
endstruct

globals
  private Net gdata
endglobals

function TimerCallback takes nothing returns nothing
  local Net data = GetTimerStructA (GetExpiredTimer ())
... //other local declarations and sh*t like that
  set gdata = data
  call GroupEnum... (whichGroup, ...)
  call ForGroup (whichGroup, whichCallback)

And then use gdata.structmember in whichCallback
