Skirmish ends only when ALL the enemy units are destroyed

Skirmish ends only when ALL the enemy units are destroyed.
It is by design.

You can replace function SinglePlayerTriggers() in scripts/stratagus.lua by something like
-- 8< --
function SinglePlayerTriggers()
  AddTrigger(
    function() return GetPlayerData(GetThisPlayer(), "NumBuildings") == 0 end,
    function() return ActionDefeat() end)

  AddTrigger(
    function()
      for i=0,PlayerMax-1 do
        if (Players[i]:IsEnemy(ThisPlayer) and
            GetPlayerData(Players[i].Index, "NumBuildings") ~= 0) then
          return false
        end
      end
      return true
    end,
    function() return ActionVictory() end)
end
-- >8 --

which is like starcraft, no building
(but since wargus game start without building, it should be something more complicated...)

Really, it may don't work(
That design is kinda weird — hunting for some one last shitty flying machine or submarine when all the war is won really pisses me off(

old design... like original warcraft 2.
with starcraft, it is better, but there is still some problem (which lead to a draw in sc2).

I may be mistaking, but as far as i can remember original warcraft 2 skirmish ended when all the unit-productive buildings (like barracks, town halls etc) were destroyed, but not when EVERYTHING is destroyed

crap, i've occasionally pressed "solve" button(( it ain't solved anyways!) sorry(
