[JASS] Group Problems

[Yin-Yang]

How would I go about checking every unit in a group with out removing them from the group?

normally I would check the first unit of the group with the FirstOfGroup() function, and then remove that unit from the group. However I now need to check through each unit in the group without removing them.

local group g = WhateverGroup
local group from = CreateGroup()
call GroupAddGroup(g, from)

Then do a FirstOfGroup() loop on from instead of g.

You can also use ForGroup, but I would recommend against that in most cases.

EF, it should be faster to:

//some global group g (for example), your original group
local group g2 = CreateGroup()
local unit u
loop
    set u = FirstOfGroup(g)
    exitwhen u == null
    //do your loop stuff
    call GroupAddUnit(g2,u)
    call GroupRemoveUnit(g,u)
endloop
call DestroyGroup(g)
set g = g2
set g2 = null

yes because GroupAddGroup isn't a native function

It has nothing to do with the fact that GroupAddGroup is or is not a native function.

ok so let's say because it call a custom function which, declare a local boolean, call a ForGroup ...

Actually, it's because with my way you're going through the group once instead of twice, and the GroupAddUnit function is used in both cases anyways.
