Not an even distribution. See http://www.hiveworkshop.com/forums/l-715/g-275344/.

bug

Leaks handle g: In Jass you must set local variables that hold agents (or any child type) to null at the end of functions to avoid reference counter leaks.

comment

note

Creates a new group object and returns it. The caller must remove it on its own after use.

return type

group

Source code

function GetRandomSubGroup takes integer count, group sourceGroup returns group
    local group g = CreateGroup()

    set bj_randomSubGroupGroup = g
    set bj_randomSubGroupWant  = count
    set bj_randomSubGroupTotal = CountUnitsInGroup(sourceGroup)

    if (bj_randomSubGroupWant <= 0 or bj_randomSubGroupTotal <= 0) then
        return g
    endif

    set bj_randomSubGroupChance = I2R(bj_randomSubGroupWant) / I2R(bj_randomSubGroupTotal)
    call ForGroup(sourceGroup, function GetRandomSubGroupEnum)
    return g
endfunction
