[Solved] [Jass] Group get unit by index?

[ThompZon]

In JASS, what is the best way of getting a unit from a group by index?

Is it even possible without shuffleing units to a temp-group and back to the original group again (like the following)?

function groupGetUnitByIndex takes group g, integer index returns unit
    local integer i = 0
    local group tempGroup = CreateGroup()
    local unit u
    local unit returnUnit = null
    loop
        set u = FirstOfGroup(g)
        exitwhen u == null
        if i == index then
            set returnUnit = u
        endif
        set i = i + 1
        call GroupRemoveUnit(g,u)
        call GroupAddUnit(tempGroup, u)
    endloop
    loop
        set u = FirstOfGroup(tempGroup)
        exitwhen u == null
        call GroupRemoveUnit(tempGroup,u)
        call GroupAddUnit(g, u)
    endloop
    call DestroyGroup(tempGroup)
    set tempGroup = null
    return returnUnit
endfunction

It is possible to have a copy of the group as an array I guess...

If you're on a patch 1.31 or later you can use

native BlzGroupUnitAt takes group whichGroup, integer index returns unit

Thanks!

The VSCode plugin I use doesn't show the new natives. I must run an old version of the plugin to show any definitions at all...
