Passing data to groups?

08-10-2008, 10:04 AM	#1
Vestras	I want to pass my struct data to groups (and I don't want to have a global struct array), now, I use HAIL, and I was wondering if you could it like this; JASS: local MyData d=GetData(whichGroup) Because that function takes a handle. Now, if I could, which group would I use?

TheDamien	Erm? The group you attached to? If you mean that you want to pass data to callbacks like ForGroup, then use globals.

Yeah, but if I should use a function?

TheDamien	I do not understand. You can not acquire the group in an Enum or ForGroup function (or at the very least I have never heard of a way), and even if there was such a way it would be slow and roundabout to pass the data using attachment. So use globals.

DioD	local struct A = MyStructCreate() A is INTEGER - struct handle then attach struct handle to group via handle vars (return bug + cache)

Use global struct variable:

JASS:

struct Data
  //...
endstruct

globals
    private Data arg_data
endglobals

private function Enum takes nothing returns nothing
    if IsUnitAlly(arg_data.caster, GetOwningPlayer(GetEnumUnit())) then
    //......
endfunction

private function Actions takes nothing returns nothing
    local Data data = Data.create()
    //...
    call GroupEnumUnitsInRange(g, AOE, null)
    set arg_data = data // set global struct variable before calling ForGroup
    call ForGroup(g, function Enum)
endfunction

Anitarf	I don't understand what application this could be used for either. If we're talking about ForGroup loops, then as others have pointed out use a global variable.
