Lua Check items in bp

[Lais Prad]

Does anyone know a function to check if the player has X items in the backpack or hands or ammo slot?
If possible, inArray .. since we will check several items.

local items = {{itemid1, count}, {itemid2, count}}
local function checkItems(player)
    for i = 1, #items do
        if not player:hasItem(items[i][1], items[i][2]) then
            return false
        end
    end
    return true
end

local items = {{itemid1, count}, {itemid2, count}}
local function checkItems(player)
    for i = 1, #items do
        if not player:hasItem(items[i][1], items[i][2]) then
            return false
        end
    end
    return true
end

I need without count, how I can do this?

if player:getItem(itemId) or player:getItem(itemId) or player:getItem(itemId) then
end

just set the count to 1

local config = {
    {id = 2160, count = 1},
}

local function checkItems(playerUid, items)
    local player = Player(playerUid)
    if not player then return false end
  
    for i = 1, #items do
        if player:getItemCount(items[i].id) < items[i].count then
            return false
        end
    end
    return true
end

            return false
        end
    end
    return true
end

but this function work inside script npc.lua ?
I tested here and nothing happens

local config = {
    {id = 2160, count = 1},
}

local function checkItems(playerUid, items)
    local player = Player(playerUid)
    if not player then return false end
    for i = 1, #items do
        if player:getItemCount(items[i].id) < items[i].count then
        npcHandler:say('Remove the items first.', cid)
       
        else
        npcHandler:say('This is good.', cid)
       
        end
    end
    return true
end

Change it to:

local config = {
    2160,
}

local function checkItems(playerUid, items)
    local player = Player(playerUid)
    if not player then return false end
    for i = 1, #items do
        if player:getItemCount(items[i]) < items[i].count then
        npcHandler:say('Remove the items first.', cid)
   
        else
        npcHandler:say('This is good.', cid)
   
        end
    end
    return true
end

local config = {
    2160,
}
local function checkItems(playerUid, items)
    local player = Player(playerUid)
    if not player then return false end
    for i = 1, #items do
        if player:getItemCount(items[i]) > 0 then
        npcHandler:say('Remove the items first.', cid)
   
        else
        npcHandler:say('This is good.', cid)
   
        end
    end
    return true
end

Sorry, didn't see it.

local items = {
    2160,
}
local function checkItems(playerUid, items)
    local player = Player(playerUid)
    if not player then return false end
    for i = 1, #items do
        if player:getItemCount(items[i]) > 0 then
        npcHandler:say('Remove the items first.', cid)
        else
        npcHandler:say('This is good.', cid)
        end
    end
    return true
end

You want to check ONLY these two slots? Because otherwise, this script will check all player items, including these slots. If you want to only check these two slots, you can use Player:getSlotItem(SLOT) and compare to the item you want to find.

Don't make a mess in the function, you can use it for other scripts later. Keep it like this:

function checkItems(playerUid, items)
    local player = Player(playerUid)
    if not player then return false end
    for i = 1, #items do
        if player:getItemCount(items[i].id) < items[i].count then
            return false
        end
    end
    return true
end

and use in npc script like:

local requiredItems= {
    {id = 2160, count = 1},
}
if checkItems(cid, requiredItems) then
    npcHandler:say('Remove the items first.', cid)
else
    npcHandler:say('This is good.', cid)
end
