Lua A Table and a Function: My Spiral Down to Madness

[Aelu]

Hey OTLand, so I have this small script snippet here:

    Mining =
{
--Foraged Minerals
    [1] = {Item = "Quartz", Price = 25},
    [2] = {Item = "Earth Crystal", Price = 50},
    [3] = {Item = "Frozen Tear", Price = 75},
    [4] = {Item = "Fire Quartz", Price = 100},
--Gems
    [5] = {Item = "Emerald", Price = 250},
    [6] = {Item = "Aquamarine", Price = 180},
    [7] = {Item = "Ruby", Price = 250},
    [8] = {Item = "Amethyst", Price = 100},
    [9] = {Item = "Topaz", Price = 80},
    [10] = {Item = "Jade", Price = 200},
    [11] = {Item = "Diamond", Price = 750},
    [12] = {Item = "Prismatic Shard", Price = 2000}
}

What I am attempting to do is something like this:

function GetItemInfo(i, p)
  local i = Mining[x].Item
  local p = Mining[x].Price
  print(i, p)
end

But I would like to be able to recall that..

x = The index value of the given table above (Mining)
i = "Item" in the index "x"
p = "Price" in the index "x

So, in essence, I'm trying to make the function "GetItemInfo()" be able to call both the item name of a given value in the table, as well as the price, so that if GetItemInfo(x) where x=1 the output would be something like..

Quartz   15

All in all, I'm attempting to index particular values from this table, so I'm able to recall the item's name OR the item's price by telling GetItemInfo(x) to search for the values of "Item" and "Price" within the table "Mining" at value "x".

function GetItemInfo(i, p)
  --Some code--
  print(i) --Prints "Quartz"
  or
  print(p) --Prints "15"

I haven't used Lua in a long ass time, and have been learning Pascal, so this is confusing me.

Thanks,
-Aelu

What are you gonna do exactly?
If you wanna get any single item from the array the table call: Mining[x].Item/Price is just good.

//
For the function you can just return an array i guess.

function getItemData(x)
  return Mining[x]
end

if you trying to access the table you need to call for an index if you already know the value or maybe just print all values with some loop

function GetItemInfo(index)
    local Mining =
    {
    --Foraged Minerals
        [1] = {Item = "Quartz", Price = 25},
        [2] = {Item = "Earth Crystal", Price = 50},
        [3] = {Item = "Frozen Tear", Price = 75},
        [4] = {Item = "Fire Quartz", Price = 100},
    --Gems
        [5] = {Item = "Emerald", Price = 250},
        [6] = {Item = "Aquamarine", Price = 180},
        [7] = {Item = "Ruby", Price = 250},
        [8] = {Item = "Amethyst", Price = 100},
        [9] = {Item = "Topaz", Price = 80},
        [10] = {Item = "Jade", Price = 200},
        [11] = {Item = "Diamond", Price = 750},
        [12] = {Item = "Prismatic Shard", Price = 2000}
    }
  local i = Mining[index].Item
  local p = Mining[index].Price
  print(i, p)
end

print(GetItemInfo(1))
--Quartz 25

  print(i, p)
end

print(GetItemInfo(1))
--Quartz 25

That's more like what I'm trying to do. However, I'm also wanting the ability to call only the name of the item or only the price of the item.
something like:

print(GetItemInfo(1.Item))

but that causes the error:

input:23: ')' expected near 'Item'

Obviously I could rewrite that into another function altogether, but it'd just be much simpler to be able to call it within the main GetItemInfo(x).

You see a Quartz. It is worth 25 gold.

That worked

That worked

The main reason for itemid is so that you have a point of reference to index the table with.

If you aren't using an itemid in your script, you'd need to provide more information on what the script is trying/meant to do and maybe we could point you to an alternative option.
