where does ChangeResouce come from? There is SetPlayerResouce
Change|Set doesn't add resources to the player, but sets them, so it should be done like this:

function regF ()
SetAmbientLight (0, "Tu", true, 5);
delta = GetPlayerResource(1, 5);
SetPlayerResource(1, 5, delta+10);
end;
Trigger (REGION_ENTER_AND_STOP_TRIGGER, "reg", "regF");

Where does ChangeResource come from? Is there a SetPlayerResource?

ChangeResource: Changes the amount of a specified resource for the player who owns the specified hero. A "floating" message appears from this hero, indicating the resource change.
playerID: Player ID
resourceKindID: Resource type ID
quantity: Amount (cannot be a negative value)
heroName: Hero name

antonag07 is right, it is clearly stated here that you should give 10 crystals. Sulfur has code 4 (or SULFUR, to avoid confusion).

ChangeResource Changes the amount of a specified resource for the player who owns the specified hero. A "flying" message appears from this hero, indicating the resource change.
playerID Player ID
resourceKindID resourceKindID Resource type ID
quantity Amount (cannot be a negative value)

Where did you get this from? I don't have these functions in the official manuals.

When creating a map, I encountered the following problem:
If you give a creature resources/an artifact, you receive them after killing it. But if it joins your army, you don't get them. Is it possible to obtain the artifact/resources only AFTER the creature joins your army, without killing it (this doesn't fit the scenario)? If it's a script, could you please share the code? :smile45:

Bulletin, `

function MonsterFunction(hero)
    Trigger(OBJECT_TOUCH_TRIGGER, 'Monster', nil);
    -- artifact
    GiveArtefact(hero, itemId);

    -- resource
    gold = GetPlayerResource(PLAYER_1, GOLD);
    SetPlayerResource(PLAYER_1, GOLD, gold+your amount);
end;

Trigger(OBJECT_TOUCH_TRIGGER, 'Monster', 'MonsterFunction');

in the monster's properties, give it a script name and set it so that it always joins.

complains that the functions MonsterFunction (monster replaced with the script name of the unit footman) and ItemId are undefined.
From the error, I only understood that I need to give an ID to the artifact. All IDs are in the file from the developers, which I don't have. But I don't quite understand what to do with the monster.

function footmanFunction(hero)
Trigger(OBJECT_TOUCH_TRIGGER, 'footman', nil);
GiveArtefact(hero, itemId);
end;
Trigger(OBJECT_TOUCH_TRIGGER, 'footman', 'footmanFunction');

where did you get this from? I don't have these functions in the official manuals.

This is from a manual by ValexAV. And crystals are just an example.

Ah, okay, it worked now.
function regF()
sulfur=GetPlayerResource(1, 4);
if sulfur>=3 then
SetPlayerResource(1, 4, sulfur-10);
end;
end;
Trigger(REGION_ENTER_AND_STOP_TRIGGER, "reg", "regF");

In the World of Enroth map, there was an object - a UFO. How do I place it on the map?

You place any hero on the map, then in the properties tree, click on "Shared." A new window will open, and there you can choose the desired object from the list of heroes (it will have the word "UFO" in its name).

Vestnik, everything was replaced correctly, only the artifact ID was used instead of itemId ;) ... oh yes, very often you also need to additionally declare parameters inside the function, like this:

function MonsterFunction(hero)
    myHero = hero; -- additionally added the hero variable
    Trigger(OBJECT_TOUCH_TRIGGER, 'Monster', nil);
    -- artifact
    GiveArtefact(myHero, 53); -- added as an example the ID of an artifact (in this case, the Tear of Ashi)

    -- resource
    gold = GetPlayerResource(PLAYER_1, GOLD);
    SetPlayerResource(PLAYER_1, GOLD, gold + your amount);
end;

Trigger(OBJECT_TOUCH_TRIGGER, 'Monster', 'MonsterFunction');

I copied the code, pasted it into the monster. I changed the function name, but nothing happened. I checked the case sensitivity (C++ is just as case-sensitive, so there are no problems with that). Do comments affect the script's functionality? Can you upload a table with item IDs, because my build doesn't have either the official manual or the table.

You don't need to put this script into a monster; instead, put it in MapScript.lua.

Here are the indexes I uploaded (see the attachments – I think everything is clear there).

How to edit a message after winning?

How do you edit a message after winning?

What do you mean? Do you want to edit the message after completing a mission and write something like "This is a real victory - not a defeat!" in it?
Well, what prevents you from creating a text file and writing what you think is necessary in it? You can do the same procedure for the message about losing ("This is your shameful defeat - not a victory!").
