Lua question: "inArea" syntax - 6/27/2017 9:33:09 PM

Another quick Lua question for those in-the-know:

I've been trying to get the program to return 'true'/'false' for me in reference to whether a selected unit/contact is in a defined area (as the Lua documentation says), but I can't figure out the correct way of doing this. I have no trouble defining an area of ref points, but I can't seem to get to give me any meaningful return.

Say, if I wanted to check whether unit MyUnit is in an area defined by points A,B,C,D. I've tried a few things, but none of them work, including...
ab = ScenEdit_GetUnit({side='MySide', name='MyUnit'})
return ab.inArea({'A','B','C','D'})

or ab.inArea{'A','B','C','D'}, or ['A','B','C','D'] or (area={'A','B','C','D'}) etc., with no luck.
I've also tried things like

MyArea = ScenEdit_GetReferencePoints({side='MySide',area={'A','B','C','D'})
ab = ScenEdit_GetUnit({side='MySide', name='MyUnit'})
return ab.inArea(MyArea)

and other things of some sort. Still nada!

If someone can help me figure out what I'm doing wrong, I'd greatly appreciate it!

Alternatively, I was wondering if I could also do something similar using a Lua condition script or a similar workaround - in this case, what I'm trying to do is create different rules for scoring the destruction of the same unit types on the same side, depending on whether they were destroyed inside a particular area, or outside of it. The only other method I can think of is a lot more unwieldy, which would basically involve temporarily changing unit sides while they are in a particular area. inArea method was what I thought would be easiest for it!

That function is not yet enabled. It is on the Command Beta page which means it is not yet available.
As I may have mentioned several times, the beta page contains things yet to be available. I will move them to the normal Command page as they are released.

Aha, I meet my nemesis the beta feature again!

I realized that when I start typing in CommandLua, it defaults to the beta page instead of the current version doc in my browser, so that explains why I keep bumping into it. Thanks!

And I did find a good enough workaround for what I was doing in any case :)

For reference, this is how I have used that function that in my testing

-- one unit has trigger event, any more in the area
local result = false
local minReq = 2
local area = {'rp-6074','rp-6075','rp-6076','rp-6077'}
local landed = ScenEdit_GetKeyValue("UnitsLandedAtBase")
local units={}
if landed == nil then
  units[1] = UnitX.guid
else
  local found = false
  for i = 1, #units
  do
    if units[i] == UnitX.guid then
      found = true
      break  -- exists in list
  end
  if found == false then
    units[#units +1] = UnitX.guid 
  end
end 

-- check if units still there
  for i = 1, #units
  do
    local unit = ScenEdit_GetUnit({guid=units[i]})
    if unit == nil then
      table.remove(units,i)
    else if unit:inArea( area ) == false then
      table.remove(units,i)
    end
  end

landed=table.concat(units,',')
ScenEdit_SetKeyValue( "UnitsLandedAtBase", landed)
return result
