Changes
add iterator enemiesByTypeAndInstallationAndBoss (a shorter name might be used...)
return Iterator.enemiesBy(context, n, function(e)
return Iterator.enemiesBy(context, n, function(e)
return e:type() == type
return e:type() == type
end)
end
function Iterator.enemiesByTypeAndInstallationAndBoss(context, n)

local predInstallation = function(e)
if selectInstallation == 'yes' then
return e._speed == 0
elseif selectInstallation == 'no' then
