Lua addEvent/stopEvent remove item

[CastorFlynn]

In this creaturescript code, when a creature is killed, a green vortex is created. If the same creature dies in the position of the green vortex, it turns purple and, with the same logic, turns red. I would like each vortex created/transformed to have 30 seconds before being removed. So if the green vortex was created, if 20sec passes and I transform it into purple it would have another 30sec until it is removed if it is not transformed into a red vortex. If it turns red, it would take another 30s until it is removed. In the current script the removal time is not "renewed/incremented".

local scheduledEvents = {}

local function removeVortex(pos)
    local vortex = Tile(pos):getItemById(26394) or Tile(pos):getItemById(26395) or Tile(pos):getItemById(26396)
    if vortex then
        vortex:remove()
    end
    scheduledEvents[pos] = nil  -- Clears the scheduled event by removing the vortex
end

local function scheduleVortexRemoval(pos)
    if scheduledEvents[pos] then
        stopEvent(scheduledEvents[pos])  -- Cancels the previous event if it exists
    end
    scheduledEvents[pos] = addEvent(removeVortex, 30 * 1000, pos)  -- Schedule a new removal event
end

local corruptedSoul = CreatureEvent("CorruptedSoul")

function corruptedSoul.onDeath(creature, corpse, lasthitkiller, mostdamagekiller, lasthitunjustified, mostdamageunjustified)
    local targetMonster = creature:getMonster()
    if not targetMonster then
        return true
    end

    local pos = targetMonster:getPosition()
    local vortex = Tile(pos):getItemById(26394) or Tile(pos):getItemById(26395) or Tile(pos):getItemById(26396)

    if not vortex then
        Game.createItem(26394, 1, pos)
        scheduleVortexRemoval(pos)
    else
        if vortex:getId() == 26394 then
            vortex:transform(26395)
        elseif vortex:getId() == 26395 then
            vortex:transform(26396)
        end
        scheduleVortexRemoval(pos)
    end

    return true
end

corruptedSoul:register()

Logic looks ok from a brief glance. It might not like using Position as a key.

Try this(untested):

local scheduledEvents = {}

local function removeVortex(pos, key)
    local vortex = Tile(pos):getItemById(26394) or Tile(pos):getItemById(26395) or Tile(pos):getItemById(26396)
    if vortex then
        vortex:remove()
    end
    scheduledEvents[key] = nil  -- Clears the scheduled event by removing the vortex
end

local function scheduleVortexRemoval(pos)
    local key = pos.x .. ":" .. pos.y .. ":" .. pos.z
    if scheduledEvents[key] then
        stopEvent(scheduledEvents[key])  -- Cancels the previous event if it exists
    end
    scheduledEvents[key] = addEvent(removeVortex, 30 * 1000, pos, key)  -- Schedule a new removal event
end

local corruptedSoul = CreatureEvent("CorruptedSoul")

function corruptedSoul.onDeath(creature, corpse, lasthitkiller, mostdamagekiller, lasthitunjustified, mostdamageunjustified)
    local targetMonster = creature:getMonster()
    if not targetMonster then
        return true
    end

    local pos = targetMonster:getPosition()
    local vortex = Tile(pos):getItemById(26394) or Tile(pos):getItemById(26395) or Tile(pos):getItemById(26396)

    if not vortex then
        Game.createItem(26394, 1, pos)
    else
        if vortex:getId() == 26394 then
            vortex:transform(26395)
        elseif vortex:getId() == 26395 then
            vortex:transform(26396)
        end
    end

    scheduleVortexRemoval(pos)
    return true
end

corruptedSoul:register()

Each time a vortex is created or transformed, scheduleVortexRemoval is called with a 30 second delay. This resets the timer to ensure the vortex will be removed after 30 seconds from the most recent transformation or creation.

local scheduledEvents = {}

local function removeVortex(pos)
    local vortex = Tile(pos):getItemById(26394) or Tile(pos):getItemById(26395) or Tile(pos):getItemById(26396)
    if vortex then
        vortex:remove()
    end
    scheduledEvents[pos] = nil
end

local function scheduleVortexRemoval(pos, delay)
    if scheduledEvents[pos] then
        stopEvent(scheduledEvents[pos])
    end
    scheduledEvents[pos] = addEvent(removeVortex, delay, pos)
end

local corruptedSoul = CreatureEvent("CorruptedSoul")

function corruptedSoul.onDeath(creature, corpse, lasthitkiller, mostdamagekiller, lasthitunjustified, mostdamageunjustified)
    local targetMonster = creature:getMonster()
    if not targetMonster then
        return true
    end

    local pos = targetMonster:getPosition()
    local vortex = Tile(pos):getItemById(26394) or Tile(pos):getItemById(26395) or Tile(pos):getItemById(26396)

    if not vortex then
        Game.createItem(26394, 1, pos)
        scheduleVortexRemoval(pos, 30 * 1000)
    else
        if vortex:getId() == 26394 then
            vortex:transform(26395)
        elseif vortex:getId() == 26395 then
            vortex:transform(26396)
        end
        scheduleVortexRemoval(pos, 30 * 1000)
    end

    return true
end

corruptedSoul:register()
