Solved How to get item ID from tile and then remove it?

[whitevo]

I have a tile where i want to reSpawn bucket every hour.
but every time the script starts i want it to first remove the all items from that tile before.
then create bucket there.

working script

local pos1 = {x=558,y=654,z=7}

function onThink()
local items = Tile(pos1):getItems()

    for i = 1, #items do
        addEvent(function() items[i]:remove() end, 1000)
    end
    addEvent(doCreateItem, 2000, 2005, 0, pos1)
return true
end

sidenote*
you don't have to use addEvent, but my script actually continues, that is why you see them here.

Spoiler

local pos1 = {x=558,y=654,z=7}

This is the tile position i want to change.

function onThink()

you can use any function you like. I use onThink because i have a globalEvent.
You can make things clean and create items for onUse or whatever else function.

local items = Tile(pos1):getItems()

under items i collect all the items what are located in position

    for i = 1, #items do
        addEvent(function() items[i]:remove() end, 1000)
    end

for every item i found in that tile: remove them all 1 sec later

addEvent(doCreateItem, 2000, 2005, 0, pos1)

2 seconds after using script (and 1 seconds after deleting all items)
makes item in the position i defined earlier
2005 is bucket and 0 means its empty.
1 would mean its water in it, etc

You need to define itemId, if itemId has no value then it will return nil.
Also why the parentheses around item in doRemoveItem?

im trying to get the item id!
This item id can be ANY of the items listed in items.xml
so definining it my own would be a hassle

 

[Jotran]

also this

addEvent(function() doRemoveItem((item).uid) end, 5000)

should be this

addEvent(doRemoveItem, 5000, item.uid)

addEvent works like this

addEvent(function name, time, arguments)

 

[whitevo]

arguements are already set inside the function..
ir works both ways imo. same result

Arguments are something that is passed to a function, a parameter would be something that you find in a function you know during the function definition?

i don't understand you..
addEvent is working.

Question is how i get item Id from the position i show and then remove that item he found.

 

[Jotran]

To answer your question getTileItemById takes 2 arguments, 1st is the position which you have defined and 2nd is the itemid to look for which you don't there is a function called getThingfromPos

getTileItemById(pos1, itemId)

your welcome

 

[whitevo]

can you post the entire script?

 

[Jotran]

can you post the entire script?

I just answered your question.
I even linked all or most of the tfs 1.0 functions

getTileItemById(pos1, getThingfromPos(pos1).itemid)

 

[whitevo]

I already knew the function.. i don't know how to use it..
You didn't answer any of my questions..

 

[whitevo]

Question 1:
How to get item ID from tile and then remove it?
your answer:
You need to define itemId

Did i ask What i have to do with this function??

Question2:
can you post the entire script?
Your answer:
I just answered your question.

local thing = Tile(pos):getItemById(1387)
if thing then
     thing:remove()
end

To remove it with addEvent

local function doRemoveSomething(pos)
     local thing = Tile(pos):getItemById(1387)
     if thing then
         thing:remove()
     end
     return true
end

addEvent(doRemoveSomething, 10 * 1000, pos)

 

[whitevo]

local thing = Tile(pos):getItemById(1387)
if thing then
     thing:remove()
end

yeah i know i can remove item like that, but problem is:
i want to get the id of the item what is on that tile.
This can be any of the items from item.xml (i have no control over what players drop on that tile)

 

[Limos]

Will this item be at the top on the tile? Then you can use getTopVisibleThing.

local thing = Tile(pos):getTopVisibleThing()
if thing and thing:isItem() and thing:getType():isMovable() then
     thing:remove()
end

To get the id incase it's needed.

thing:getId()

 

[whitevo]

ye i was messing with the getTopVisible thing, but didnt know how insert the tile position.

function onThink()
local thing = Tile(pos1):getTopVisibleThing(player)

if thing:isItem() then
    addEvent(function() thing:remove(tonumber(param) or -1) end, 5000)
end

this is working, BUT it even removes the tile itself xD (making it a void area, that was funny but also not what i had in mind)

Just clean the tile? doCleanTile

 

[Ninja]

Use tile:getItems()

local items = tile:getItems()
for i = 1, #items do
    items[i]:remove()
end

 

[whitevo]

script with getItems()
Result: attempt to call getItems() a nil value

local pos1 = {x=558,y=654,z=7}

function onThink()
local items = pos1:getItems()

    for i = 1, #items do
        addEvent(function() items[i]:remove() end, 5000)
    end
    addEvent(doCreateItem, 6000, 2005, 0, pos1)
return true
end

script with doCleanTile
result: attempt to call global doCleanTile (a nil value)

local pos1 = {x=558,y=654,z=7}

function onThink()
    addEvent(function() doCleanTile(pos1) end, 5000)
    addEvent(doCreateItem, 6000, 2005, 0, pos1)
return true
end

Tile(pos1):getItems()
