[JASS] Group = Group == Copy or pointer...

[Preskooldude]

Let's say I have two group variables,

local group GroupA
local group GroupB

Now I'll set one of them to a new group. add some units, then set Group B to Group A...

 set GroupA = CreateGroup() 
call GroupAddUnit(GroupA,Whatever)
//---snip---
set GroupB = GroupA

OK: What will happen if I edit group B? Will GroupA Also be affected (As they would if they were C pointers?)?

All handles are pointers, yes.

So the only way I can circumvent this is to... use GroupAddGroup?

Not the only one but the best.

If you're enuming anyways it's faster to just add it as the loop goes through.

Eg:

local group g = CreateGroup()
local group g2 = CreateGroup()
local unit u
//enum for g
loop
    set u = FirstOfGroup(g)
    exitwhen u == null
    call GroupAddUnit(g2,u)
    call GroupRemoveUnit(g,u)
    //do other stuff you would do in the loop
endloop

GroupAddGroup would be faster and not screw up the first group.

GroupAddGroup would be faster and not screw up the first group.

I was making the assumption the first group was already in said loop for other purposes.

Thanks for the advice. +Rep to all people involved.
