Display an array element

[Blade33711]

How to do to display an array element?

function onUse(cid, item, frompos, item2, topos)
local items = {["reward"] = {item = 1111, pos = {x=1000, y=1000, z=7}}
doPlayerSendTextMessage(cid, MESSAGE_STATUS_CONSOLE_ORANGE, "".. items[1] ..".")
end

you can access table elements by using the . operator (only works for string keys) or [] (works for integers & strings)
you're trying to access items[1] when index 1 doesn't exist, i assuming you're trying to access "reward"
stuff like ["reward"] = and reward = is interpreted as a string key, so you can access it with items.reward since they're strings
after which you can get the item id by doing this:
items.reward.item -- would be 1111
you can learn more about this here: Lua Tables
you also dont need to concatenate (see Programming in Lua : 3.4) empty strings to your value, you can simply do: items.reward.item .. "."
the end product would be this:

-- define items once every time the script is loaded, instead of having it re-defined every time onUse runs
local items = {
    reward = {item = 1111, pos = {x=1000, y=1000, z=7}
}

function onUse(cid, item, frompos, item2, topos)
    doPlayerSendTextMessage(cid, MESSAGE_STATUS_CONSOLE_ORANGE, items.reward.item ..".")
    return true
end

Ty, but it didn't work for:

doPlayerSendTextMessage(cid, MESSAGE_STATUS_CONSOLE_ORANGE, items.reward.pos ..".")

Error:
attempt to concatenate field 'pos' (a table value)

because you cant concatenate table values, you have to use a string or number

doPlayerSendTextMessage(cid, MESSAGE_STATUS_CONSOLE_ORANGE, ("X: %d, Y: %d, Z: %d"):format(items.reward.pos.x, items.reward.pos.y, items.reward.pos.z))

this gets the x y z values and places them in each %d in order

Ty! One more question. How to display this array?

local cfg = {items = {2342, 2354, 2564}}

Ty! One more question. How to display this array?

local cfg = {items = {2342, 2354, 2564}}

if you want to just print out the array you can do this

for k, v in pairs(cfg) do
    print(k, v)
end

but to print it to the player you'd have to do the same thing but instead of print you'd do doPlayerSendTextMessage, and you'd have to convert tables and shit to strings using tostring
