Current questions and answers regarding the map editor.

I don't remember being asked to write a script, but my idea is generally similar to Jewill's script. Only, I'm not a very good programmer (I don't really understand tables; 2D arrays are closer to me). It should be taken into account that there are also weeks of mining 2x (wood + ore), as well as the same for Sulfur + Mercury and Crystals + Gems, the names of which I don't remember. And another week for gold.

You can also do this using a while 1 do loop. Where mines that don't pass the check for the presence of creatures become neutral.

--Name all mines with the same name plus a number starting from 1 and onwards: For example, mine1, mine2, mine3, mine4, etc.                                                                                                                  
                                   

while 1 do
 sleep(10);
 for i = 1,"number of mines on the map" do  --"number of mines on the map" replace with the number
  if GetObjectCreatures("mine"..i,"creature ID") == 0 and GetObjectOwner("mine"..i) ~= 0 then --replace "creature ID" with the desired creature ID
   SetObjectOwner("mine"..i,0);
  end;
 end;
end;

However, something is needed to stop the mine from becoming neutral when a hero captures it and places creatures in the garrison. Otherwise, the mine will become neutral, and you will have to fight these creatures. Something like a region around the active tile of the mine and a condition that if there is no hero in the region, then SetObjectOwner("mine"..i,0) is executed. But I think there is a better idea, but it doesn't come to mind yet.
