SetRegionBlocked("region name", true, PLAYER_N)

Replace N with the player's number.

During map verification, I encountered an unknown issue: for some reason, water appeared in areas of the map where it shouldn't be. I don't know how to explain it more clearly; here are some screenshots.

The water issue might occur if you select water and the "up" parameter; in that case, water will only be visible on the minimap.

Thank you, another question. Does the script only work on AI? I switched to the enemy hero (player 8) to check if it worked, but it didn't. I wrote it like this: SetRegionBlocked("un", true, PLAYER_8);
Okay, it worked. I just needed to remove the spaces, thanks :)

Also, here's another question: I want to make it so that after losing a battle, the enemy hero always appears in their own town. (Like in the "Hammers of Fate" campaign for Wulfstan. There, Lorenzo and other red knights had this ability.) I've been looking for the right script, but I haven't found it. Maybe someone knows it?

so that the enemy hero, after losing a battle, always reappears in their city.

There are 2 options.
1) Force him to reliably reappear in the tavern after defeat. See the MakeHeroReturnToTavernAfterDeath function.
2) Place the hero in reserve and create a trigger for his loss. At the beginning of the game, and after each of his losses, deploy him (see DeployReserveHero) to a specific location on the map.

a specific location on the map.

Thank you. I think the second option suits me. And will all the hero's skills/experience be preserved?

Hey guys. I have a problem. I'm generating a random map in the editor. If I don't change anything on it, we can play online with friends without any issues. But if I change something, for example, create alliances, then no one can join my game on that map. Also, when saving the map, it says: "As you've changed this map, the rmg marker will be lost, and multiplayer regeneration won't work." How can I fix this?

You can open the map using an archiver and manually edit the map.xdb (or map-tag.xdb) file inside. I haven't done this in ages, but there's a line that says something like "random map" or similar. In any case, you can simply compare the files.

PlayObjectAnimation ('object name', attack01, IDLE)
What should I put instead of 'object name'?
For example, I need an armored knight. Should I put 6, or ID_6, or something else?

Enter the object's name, and this name will be inserted.

Ment, thank you! It worked out. Just in another section, the value needed to be changed. Can I ask another question? How do I disable the ability to create portals before generating a map? They ruin the whole game.

I don't know... Perhaps you need to find suitable templates, or use the IRMG editor; maybe the "zones" work differently there.

How to disable fog in the map editor?

How do I disable the fog in the map editor?

If you're talking about the fog of war, you can remove it using a script:

for floor = 0, GetMaxFloor() do
    OpenCircleFog(0, 0, floor, 1000, PLAYER_1)
end

No, not about him.
I meant the fog over the land.

Choose lighting without fog or remove it in the existing lighting by adjusting the DistanceFog property.
