TFS 1.X+ Fix Spell tfs 1.4.2

What's up guys! I have a Spell but I wanted it to follow my character, can someone tell me a way to do that?

Code:

function spellCallback(cid, position, count)
    if Creature(cid) then
        if count > 0 or math.random(0, 1) == 1 then
            position:sendMagicEffect(CONST_ME_HITBYFIRE)
            doAreaCombat(cid, COMBAT_FIREDAMAGE, position, 0, -100, -100, CONST_ME_EXPLOSIONHIT)
        end

        if count < 5 then
            count = count + 1
            addEvent(spellCallback, math.random(1000, 4000), cid, position, count)
        end
    end
end

function onTargetTile(creature, position)
    spellCallback(creature:getId(), position, 0)
end

local combat = Combat()
combat:setArea(createCombatArea(AREA_CIRCLE5X5))
combat:setCallback(CALLBACK_PARAM_TARGETTILE, "onTargetTile")

function onCastSpell(creature, variant, isHotkey)
    return combat:execute(creature, variant)
end

In Game:

When I walk to the left she continues in the position where I cast her. My goal is to keep this randomness in the hits but I want it to follow my character.

You must only take the player's position each time the spell function is executed.

Something like this:

function ExampleRepeat(player)
    local pos = player:getPosition()
    print(pos)
    addEvent(ExampleRepeat, 1000, player)
end

Something like this:

function ExampleRepeat(player)
    local pos = player:getPosition()
    print(pos)
    addEvent(ExampleRepeat, 1000, player)
end

result:

it went wrong because the "position" that I pass to the spellCallback() function is the position where the hit goes and not the position of the player.

I managed to find a solution!!
After a long time testing I came up with this result:

local combat = Combat()
combat:setArea(createCombatArea(AREA_CIRCLE5X5))

function getRandomPositions(cid)
    local player = Player(cid)
    local playerPos = player:getPosition() 

    local areaCircle5x5 = {} -- creates a new AREA_CIRCLE5X5 based on my character's position
    for i = -5, 5 do
        for j = -5, 5 do
            local dist = math.sqrt(i^2 + j^2)
            if dist <= 5 then
            table.insert(areaCircle5x5, {x=playerPos.x+i, y=playerPos.y+j, z=playerPos.z})
            end
        end
    end

    local randomPosition = {}
    for i = 1, 1 do
        local index = math.random(1, #areaCircle5x5)
        table.insert(randomPosition, areaCircle5x5[index])
    end
    return randomPosition
end

function spellCallback(cid, position, count, maxCount)
    if Creature(cid) and count < maxCount then
        if count == 0 and math.random(0, 1) == 1 or math.random(0, 15) == 1 then
            position:sendMagicEffect(CONST_ME_MORTAREA)
            doAreaCombat(cid, COMBAT_DEATHDAMAGE, position, 0, -100, -100, CONST_ME_EXPLOSIONHIT)
        end

        count = count + 1
      
        local area = getRandomPositions(cid)
        local positionAreaCircle = {x= area[1].x, y= area[1].y, z= area[1].z}
        local position1 = Position(positionAreaCircle)

        if count > 1 and count < 81 or count > 81 and count < 145 then
            addEvent(spellCallback,50, cid, position1, count, maxCount)         
        else 
            addEvent(spellCallback,math.random(1000, 2000) , cid, position1, count, maxCount)     
        end

        if count > 141 then           
            addEvent(spellCallback,math.random(600, 3000) , cid, position1, count, maxCount) 
        end
    end
end

function onTargetTile(creature, position)
    local maxCount = 145 
    spellCallback(creature:getId(), position, 0, maxCount)
end

combat:setCallback(CALLBACK_PARAM_TARGETTILE, "onTargetTile")

function onCastSpell(creature, variant, isHotkey)
    return combat:execute(creature, variant)
end

In game:

thanks anyway @Drucken
