Any help with using those tables? I did say I was terrible with them? Please?

Code: Select all

local function addItemToInventory(inventory,item,amount)
	if (inventory[item] ~= nil) then
		inventory[item] = inventory[item] + amount
	else
		inventory[item] = amount
	end
end

local function removeItemFromInventory(inventory,item,amount)
	if (inventory[item] == nil) then return end
	
	if (inventory[item] <= amount) then
		inventory[item] = nil
	else
		inventory[item] = inventory[item] - amount
	end
end

local function printItemsInInventory(inventory)
	for item,amount in pairs(inventory) do
		if (type(item)=="table") then
			print(item.name or "Unknown",amount)
		else
			print(item,amount)
		end
	end
end

local myInventory = {}

local myItem = "hammer"
local myUniqueItem = {name="superhammer",bonus=5}

addItemToInventory(myInventory,myItem,10)
addItemToInventory(myInventory,myUniqueItem,1)
removeItemFromInventory(myInventory,myItem,4)

printItemsInInventory(myInventory)

Thanks, that's all I needed. explanation would have been nice, but I think I understand. Sorry for being such a pain. Plus: I did understand tables, and I did watch SockMunkee's videos. I think I know what I know, if you know what I mean.

you should try before asking for help, just like i did back in my noob days.

I've tried messing about with it, but to no avail. I've tried what I've tried, and I feel as though your judging me.

Of course, who doesn't judge others?
