Hey, should I set variable
u
to nil inside ForGroup
, or it is not necessary?
Lua:
function Group_Mixed(g)
local walkers=false
local flyers=false
ForGroup(g, function()
local u = GetEnumUnit()
if UnitAlive(u) then
if IsUnitType(u, UNIT_TYPE_FLYING) then
flyers=true
elseif not IsUnitLoaded(u) then
walkers=true
end
end
u=nil
end)
return walkers and flyers
end
