Problems with tables

[Simi23]

Hi there! There is my code, but it doesn't work good. My goal is to list 5 random strings in the chat but the first in the chat is always "nil". Why?

local pizzas = {"Hawaii", "Sonkás", "Sajtos", "Tonhalas", "Négysajtos"}
local deliver = {}

function starter()
        local counter = 1
        while counter <= 5 do
            local num = math.random(0,4)
            counter = counter + 1
            table.insert(deliver, tostring(pizzas[num]))
        end
        setTimer(
        function ()
        outputChatBox("Megkaptad a rendelést, most szállítsd le a következő pizzákat: "..tostring(deliver[0])..", "..tostring(deliver[1])..", "..tostring(deliver[2])..", "..tostring(deliver[3])..", "..tostring(deliver[4]).."!")
        end ,5000,1)
end

addCommandHandler("deliver", starter)

Arrays in lua start at index 1, so at line 13 when you are outputting deliver[0] the value will be nil

Also change at line 7 the random argument to 1,5

Another optional thing is to convert the while loop at line 6 with a for loop

 

The code should be this (not tested):

local pizzas = {"Hawaii", "Sonkás", "Sajtos", "Tonhalas", "Négysajtos"}
local deliver = {}

function starter()
	for counter=1,5 do
		table.insert(deliver, tostring(pizzas[math.random(1,5)]))
	end
	setTimer(
		function()
			outputChatBox("Megkaptad a rendelést, most szállítsd le a következő pizzákat: "..tostring(deliver[1])..", "..tostring(deliver[2])..", "..tostring(deliver[3])..", "..tostring(deliver[4])..", "..tostring(deliver[5]).."!")
		end,
    5000, 1)
end
addCommandHandler("deliver", starter)

Note that in deliver there could be duplicates of one item of pizzas, and some items could not appear. Not sure if this is a problem for you anyway, maybe this is what you want. Just wanted to make sure you know this. 

Hope it solved your problem

Thanks, it helped me. There are pizza requests for a pizzaboy work. It's not problem if one of the items not shown.
