Help a new Coder find his Error

[KingNicoLp]

So im fairly new to Lua and to coding in general so please forgive my stupidity.
Anyways my plan was if someone presses a the given key than the server should take a Veste away from ur inventory and after than give u an animationen. This works just fine the problem is it still give u the animation and the armor even if u dont have a veste anymore and thats the point where i need help.

So add in a check if the player “has” the item.

[KingNicoLp]

yeah but how do i do that

[hallux]

I believe a simple if then statement should work here… Basically think if the player has the item required, then.

[KingNicoLp]

yeah ok but what i wanted to know is what to put after if and befor then

[hallux]

Oh… so you want someone to write the rest of the code for you rather then learning how to do it yourself?

/me exits stage left…

me remembers why i never used forums

You need to store the player inventory in a list.
then you loop through and check if that list contains the item already.

I could be wrong anyone correct me if i am, im a C# coder lol

-- Client side implementation

local inventory = {'item1', 'item5', 'item 9'}

function hasItem(itemName)
	for i, name in ipairs(names) do
		if name == item then
			return true
		end
	end
	return false
end

if not hasItem("item5") then
	table.insert(inventory, "item5")
end

If you want it to be server side

local playerInventories = {}

function createPlayer(playerHandle)
	local player = {}
	player.Handle = playerHandle
	player.Inventory = {}
	return player
end

function createItem(itemName)
	local item = {}
	item.name = itemName
	return item
end

function getPlayerInventory(playerHandle)
	for i, player in ipairs(playerInventories) do
		if player.Handle == playerHandle then
			return player.Inventory
		end
	end
end

function addItemToPlayerInventory(playerHandle, item)
	table.insert(getPlayerInventory(playerHandle), item)
end

function hasPlayerItemInInventory(playerHandle, itemName)
	for i, item in ipairs(getPlayerInventory(playerHandle)) do
		if item.name == itemName then
			return true
		end
	end
	return false
end

...onPlayerConnecting
	createPlayer(src)

...onPlayerPickupItem
	local item = createItem("the item name")
	if not hasPlayerItemInInventory(src, item) then
		addItemToPlayerInventory(src, item)
	end
