TFS 1.X+ Mana cost per Second

[kubix333]

TFS 1.3
Hello, I have a problem, so I wanted to make a spell for a knight which would give him more damage, but for every second he would take 5 mana or life. Can somebody explain it to me how can you make such a spell?
And if there is not enough life or mana, the spell turns off.

local config = {
    milliseconds = 15000,
    interval = 1000,
    damage = 5,
    mode = 'health',
    minimum = 3000
}

function siphon(mode, dmg, minimum, interval, milliseconds, n)
    n = n or 1
    if n * interval >= milliseconds then
        return
    end
    if mode == 'health' then
        local newHealth = player:getHealth() - dmg
        if newHealth < minimum then
            return
        end
        player:addHealth(-dmg)
    elseif mode == 'mana' then
        local newMana = player:getMana() - dmg
        if newMana < minimum then
            return
        end
        player:addMana(-dmg)
    end
    addEvent(siphon, mode, dmg, minimum, interval, n + 1)
end

function onCastSpell(creature, variant)
    siphon(config.mode, config.damage, config.minimum, config.interval, config.milliseconds)
    return true
end

Then you'll have to add a storage value in the spell and register an onHealthChange/onManaChange creaturescript for every creature on the server and multiply damage if the attacker has that storage value (buff active), and remove storage value when <minimum hp/mana or when siphon ends (before return).

How to use in talkactions to cost mana per second ? e.g -100 mana per second

 

[Infernum]

The exact same way I called siphon inside of onCastSpell.

if you can explain it to me exactly because I can't understand it.

player:getHealth() < dmg -> player:getHealth() - dmg
same with mana, or am I wrong?

Tell me what i need add to creaturescript ?

Tell me what i need add to creaturescript ?

what creature script? the script he provided will do everything you need just check the config.

local config = {
    milliseconds = 15000, -- will last 15 seconds
    interval = 1000, -- every 1 second
    damage = 5, -- will do 5 damage
    mode = 'health', -- to your health
    minimum = 3000 -- until you are 3k hp
}

lmao it its actually wrong, give me a few
test this one.

local config = {
    milliseconds = 15000,
    interval = 1000,
    damage = 5,
    mode = 'health',
    minimum = 3000
}

function siphon(p, mode, dmg, minimum, interval, milliseconds, n)
    n = n or 1
    local player = Player(p)
    if not player or n * interval >= milliseconds then
        return
    end
    if mode == 'health' then
        local newHealth = player:getHealth() - dmg
        if newHealth < minimum then
            return
        end
        player:addHealth(-dmg)
    elseif mode == 'mana' then
        local newMana = player:getMana() - dmg
        if newMana < minimum then
            return
        end
        player:addMana(-dmg)
    end
    addEvent(siphon, player, mode, dmg, minimum, interval, n + 1)
end

function onCastSpell(creature, variant)
    if creature:isPlayer() then
        siphon(creature, config.mode, config.damage, config.minimum, config.interval, config.milliseconds)
    end
    return true
end

can you test it again with the new changes I've made
edit. after some testing now its working

local config = {
    milliseconds = 15000,
    interval = 1000,
    damage = 5,
    mode = 'health',
    minimum = 3000
}

function siphon(player, mode, dmg, minimum, interval, milliseconds, n)
    n = n or 1
    local player = Player(player)
    if player then
        if n * interval >= milliseconds then
            return
        end
        if mode == 'health' then
            local newHealth = player:getHealth() - dmg
            if newHealth < minimum then
                return
            end
            player:addHealth(-dmg)
        elseif mode == 'mana' then
            local newMana = player:getMana() - dmg
            if newMana < minimum then
                return
            end
            player:addMana(-dmg)
        end
        addEvent(siphon, interval, player:getId(), mode, dmg, minimum, interval, milliseconds, n + 1)
    end
end

function onCastSpell(creature, variant)
    if creature:isPlayer() then
        siphon(creature:getId(), config.mode, config.damage, config.minimum, config.interval, config.milliseconds)
    end
    return true
end
