Scripts

Good afternoon, I have a simple task: to create a script in the map editor that, for example, when a neutral creature is killed, any hero who does it receives X experience.

But I can't seem to implement it. What's the error here?

GetPlayerHeroes(0);
SetGameVar(whotoup, 0);
whotoup = GetPlayerHeroes(0);
ChangeHeroStat(whotoup[0], 0, 999999999)

You can achieve a simpler result with workarounds, but if you need precise logic, so that ANY hero receives experience for defeating a SPECIFIC stack, and not a total number of creatures, here's my idea:

Give a name to the unit on the map. For example, UnitExp

function FightUnitExp(hero, unit)
 while isObjectExists(hero) == not nil and isObjectExists(unit) == not nil do
  sleep(5)
 end 
 if isObjectExists(unit) == nil then
  ChangeHeroStat(hero, 0, 999999999)
 end
end
Trigger(OBJECT_TOUCH_TRIGGER, "UnitExp", "FightUnitExp")
