Lua Get item count/fluid type on a specific tile

[Unknown Soldier]

Hello,

I thought it would be pretty simple to get the position and amount of items on the ground, but got no results. So the thing is, that I want to check if a fluid container (a vase for instance) at certain position is filled with certain fluid like water or blood or whatever fluid type it is. Can somebody give me a hint? TFS 1.4.2

local item1pos = Position(100, 100, 7)
local item1 = Tile(item1pos):getItemById(12345)
if item1:getCount() == 2 then --2 is for blood
...something...
end

That's where I am stuck...

Thanks in advance

local itemId = 12345
local position = Position(100, 100, 7)
local tile = Tile(position)
if not tile then
    return
end

local items = tile:getItems()

for i = 1, #items do
    local item = items[i]
    if item:getId() == itemId then
        if ItemType(itemId):isFluidContainer() then -- don't really need this, but added for extra good measure. xP
            local fluidType = item:getFluidType()
            if fluidType == FLUID_WATER or fluidType == FLUID_BLOOD then
                -- do something
                break
            end
        end
    end
end

Thanks for quick reply! It's almost working! ^^
Made a lever script using your code, but it doesn't go inside last "if", so after checking fluid type, as a result "cc" is not printed. Where could be an error?

function onUse(player, item, fromPosition, target, toPosition, isHotkey)

local itemId = 33883
local position = Position(2098, 1238, 10)
local tile = Tile(position)
if not tile then
    return
end
 
if item.itemid == 1945 then
item:transform(item.itemid == 1946 and 1945 or 1946)
print("aa")
local items = tile:getItems()
for i = 1, #items do
    local checkitem = items[i]
    if checkitem:getId() == itemId then
        if ItemType(itemId):isFluidContainer() then
            local fluidType = checkitem:getFluidType()
            print("bb")
            if fluidType == FLUID_BLOOD then
                print("cc")
                break
            end
        end
    end
end

elseif item.itemid == 1946 then
item:transform(item.itemid == 1945 and 1946 or 1945)
end

end

end

not sure.

I added a few more prints after bb to help figure out the issue.

    local position = Position(2098, 1238, 10)

    if not tile then
        return
    end
    
    if item.itemid == 1945 then
        item:transform(item.itemid == 1946 and 1945 or 1946)
        print("aa")
        local items = tile:getItems()
        for i = 1, #items do
            local checkitem = items[i]
            if checkitem:getId() == itemId then
                if ItemType(itemId):isFluidContainer() then
                    local fluidType = checkitem:getFluidType()
                    print("bb")
                    print(fluidType .. " is fluid in container")
                    print(FLUID_BLOOD .. " is fluid blood")
                    if fluidType == FLUID_BLOOD then
                        print("cc")
                        break
                    end
                end
            end
        end
    
    elseif item.itemid == 1946 then
        item:transform(item.itemid == 1945 and 1946 or 1945)
    end
    return true
end

Those prints helped, thank you Xikini, once again it didn't want to use FLUID_BLOOD (error message below), when used a number instead, it works fine.
