Passing struct data to ForGroups.

Vestras	How? If now, we say, I got a struct, and I want the data in a function that I use for ForGroup, then what would I do?

Alexander244	Pass the struct instance with a global variable.

Yeah, but I don't understand those...

JASS:

struct structtype
    //...
endstruct

globals
    structtype TempStruct
endglobals

function TheForGroup takes nothing returns nothing
    //use TempStruct
endfunction

function SomeFunc takes nothing returns nothing
    //...
    set TempStruct = StructInstance
    call ForGroup(g, function TheForGroup)
endfunction

What is the StructInstance? And you don't have to have the global block below the structs.

Alexander244	StructInstance is whatever struct instance you're using.

Vestras	I must have missed something, or else I'm just too tired, struct instance?

07-27-2008, 08:03 AM	#8
Alexander244	You generally work with struct instances, unless you're just using static members?

Vestras	But then it won't be MUI?

07-27-2008, 08:24 AM	#10
Alexander244	Gnerally it won't be MUI if your not using seperate struct instances to store your data, no.

07-27-2008, 09:03 AM	#11
Vestras	And that's the thing I understand how to. It's something with a global integer, right?

What?

And the struct instance is just

JASS:

local StructName dat1 = StructName.create () //for example
//Could also be retrieving the struct from something rather than declaring a new one i.e.
local StructName dat2 = GetTimerStructA (GetExpiredTimer ()) //or whatever system you use/handle you want to retrieve from

globals do not automatically make something non-MUI, just like locals/structs won't automatically make something MUI.

DioD	You do not need structs for this. Just pass data into globals and then read this data from ForGroup call. Nothing can change your data before ForGroup finished (expect event generating actions, soo evoid using same globals everywhere)

You can have a temporary global variable, you set it to whatever struct you are working with and then call the ForGroup. In the callback function you use this global variable. It will be MUI as long as the rest of the code is MUI because this global variable is used only while your trigger is running, and, unless you do something in the callback which might cause the same trigger to activate again (which you shouldn't do), your trigger have only one running instance at a time so it should be all right.
