Scripts

Good day! I need help with a script. I created a special ability for a hero, so that if, during a battle, less than 30% of creatures remain in his army, Death Wraiths are summoned in the amount of HeroLevel * 0.05. But I doubt that this will work...

function Start()
 if GetHeroName(GetAttackerHero())=="HafadNecro" then
 side=ATTACKER
 aside=DEFENDER
 start_creatures=CountCreatures(side)
 elseif GetHeroName(GetDefenderHero())=="HafadNecro" then
 side=DEFENDER
 aside=ATTACKER
 start_creatures=CountCreatures(side)
 end
end
function CountCreatures(_side)
 local fc_count=0
 for key, element in GetCreatures(_side) do
 fc_count=fc_count+GetCreatureNumber(element)
 end
 return fc_count
end
function UnitDeath(unit)
 sleep(4)
 if intg(start_creatures*0.30)<=CountCreatures(side) then
 for key, name in GetCreatures(aside) do
 SummonCreature(side, CREATURE_WRAITH, 0.05*GetHeroLevel("HafadNecro"), 12, 2)
 end;
 end;
end;
