Scripts

when the main creatures are destroyed, the summoned creatures disappear

The next argument after x, y, SummonCreature, if equal to nil, creates a real squad.
The second option: do not allow the battle to end automatically until at least one side has a squad. For example, this is how I implemented the battle with a mage in the fifth mission.

function finish()
	EnableAutoFinish(nil)
	while not combatStarted() do
		sleep(20)
	end
	while GetCreatures(0)[0] and GetCreatures(1)[0] do
		sleep(20)
	end
	EnableAutoFinish(1)
end

startThread(finish)
