Posts from Scripts for beginners.

Hello everyone. Maybe someone can help me with a script where all mines only provide resources if a certain number of, for example, level 1 units are stationed in them (in the garrison – inside the mine).

My dear friends! Could anyone spare a few minutes to help me out?
I'm trying to create a script that doubles the army size. I borrowed the script from "Random Wars" as a base.
[spoiler=This works, but only for one hero]
function incom()
local day = GetDate(3)
if day == 2 then
        local hero = GetPlayerHeroes(5)[0]
        local types = {}
        types[0], types[1], types[2], types[3], types[4], types[5],types[6] = GetHeroCreaturesTypes(hero)
        for i = 0, 6 do
        if HasHeroCreature(hero, types)
        then
                --local stack = GetCreatureById(types)
                local amount = GetHeroCreatures(hero, types)
                AddHeroCreatures(hero, types, amount, i)
            end
        end
    end
end

Trigger(NEW_DAY_TRIGGER, "incom")

I want to implement a scheme with multiple heroes, but I don't know how to write it correctly.
[spoiler=Doesn't work]
function incom()
local day = GetDate(3)
if day == 2 then
    local hero = {}
    hero[0], hero[1], hero[2], hero[3] = GetPlayerHeroes(5)
    for k = 0, 3 do
    if IsHeroAlive(hero)
    then
        local types = {}
        types[0], types[1], types[2], types[3], types[4], types[5],types[6] = GetHeroCreaturesTypes(hero)
        for i = 0, 6 do
        if HasHeroCreature(hero, types)
        then
                local stack = GetCreatureById(types)
                local amount = GetHeroCreatures(hero, types)
                AddHeroCreatures(hero, types, amount, i)
                end
                end
            end
        end
    end
end

Trigger(NEW_DAY_TRIGGER, "incom")

The function IsHeroAlive(hero) produces an invalid argument #1, i.e., instead of 'hero', something inedible appears.

The thing is, the GetPlayerHeroes function itself returns an array, so the values of the array fields "heroes" from 2 to 5 are nil, and the first one is a table. The same applies to the "hero" table itself, so in your case, both IsHeroAlive(hero) and IsHeroAlive(hero[k]) will fail – with the error you specified. Therefore, you need to copy the table from the GetPlayerHeroes function into a local array called "heroes," then iterate through the array and perform the specified actions. ```lua function incom() local day = GetDate(3) if day == 2 then local heroes = GetPlayerHeroes(5) for k, hero in heroes do if IsHeroAlive(hero) then local types = {} types[0], types[1], types[2], types[3], types[4], types[5], types[6] = GetHeroCreaturesTypes(hero) for i = 0, 6 do if HasHeroCreature(hero, types[i]) then local stack = GetCreatureById(types[i]) -- If you copied this from RW, I hope you also copied the GetCreatureById function. local amount = GetHeroCreatures(hero, types[i]) AddHeroCreatures(hero, types[i], amount, i) end end end end end end Trigger(NEW_DAY_TRIGGER, "incom")

I bow to you, Most Wise Wizard! Without a ready-made script, I wouldn't have understood anything, as I am uneducated. And yes, the function exists, but I have removed (commented out?) the local stack because it is unnecessary.

I advise you to follow the link in the signature of the respected Wizard; in the Files section, you will find an invaluable library of Scripting (and other) Arts, authored by Hottabych and other Atlantean mapmakers.

Hello! Can anyone tell me how to create a script so that on a specific day, a creature building of a certain level is constructed in a town, if this building was previously prohibited. (i.e., for example, creatures of level 7 cannot be built in a town, but after 2 weeks, it becomes possible, and the building is constructed automatically, or the building becomes available). If such scripts can be made, of course. Thank you. Sorry, I don't understand anything about scripts...
In my case, I want to make it so that after 14 days, it becomes possible to build Titans in the Academy, even though creatures of level 7 could not be built before.
P.S. I apologize for my noob question, but I have reviewed all the previous pages and did not find such a question or script.

function NewDay() if GetDate(DAY) == 14 then UpgradeTownBuilding("Town", TOWN_BUILDING_DWELLING_7, level) -- 0 - not built, 1 - built, 2 - upgraded end end Trigger(NEW_DAY_TRIGGER, "NewDay")

function NewDay()
if GetDate(DAY) == 14 then
  UpgradeTownBuilding("Town", TOWN_BUILDING_DWELLING_7, level) --0— not built, 1 — built, 2 — upgraded
end
end

Trigger(NEW_DAY_TRIGGER, "NewDay")

Thank you very much, boss!

Good day! Could someone suggest a script that, upon capturing a Haven city, would delete that city and replace it with a ruined city?

Good day! Could someone suggest a script that, when a Haven town is captured, the town is removed and replaced with a ruined town?

There is a script command called RazeTown("script name of the town"). It can be used by default to destroy the castles of Humans and Demons. For the castles of other factions, you need to make some adjustments.

Could you explain? I searched through the game files and found this script, but unfortunately, I didn't understand anything.
Thank you in advance.

function CaptureTown()
RazeTown('your town name')
end

Trigger(OBJECT_CAPTURE_TRIGGER, 'your town name', 'CaptureTown')

It's simple: you assign a script name to the town in the map editor, and then you write something like this function in the script editor.

Could someone explain how to use the SetObjectiveState script? Many people suggested using it when I asked how to create an object that gives a quest.
Ideally, with examples, because I won't understand much without them.

SetObjectiveState changes the state of a quest with the name objectiveName for a specific player. For quests belonging to a specific player, the playerID parameter is ignored. For global quests, if the playerID parameter is specified, it indicates for which player the quest state should be changed; otherwise, the quest state is changed for the first player.

In simple terms, the script activates a quest, completes/fails it.

SetObjectiveState("prim1", OBJECTIVE_ACTIVE) -- the first parameter is the quest name, the second is the status.
function PRIM3_COMPL()
Trigger(REGION_ENTER_AND_STOP_TRIGGER, '4', nil)
if GetCurrentPlayer()==1 then
SetObjectiveState("prim3", OBJECTIVE_COMPLETED) -- the same, but with a different quest status.
print("32")
end
end

Trigger(REGION_ENTER_AND_STOP_TRIGGER, '4', 'PRIM3_COMPL')

BlueHeavenHero,

OBJECTIVE_ACTIVE - makes a quest active, meaning it can be completed and will be displayed to the player(s).

OBJECTIVE_COMPLETED - completes a quest.

OBJECTIVE_FAILED - fails a quest.

The OBJECTIVE_UNKNOWN status is also used for various situations, mainly in the GetObjectiveState function, to check if the quest has already been issued, in other words, if it doesn't have one of the previously mentioned statuses.

P.S. I can also add that you can set the "CanUncomplete" property of quests to "true," which will allow you to restart quests, i.e., make completed quests active again.
