Lua Virtual Goods

This tutorial will demonstrate Virtual Goods purchases and viewing player records.

Purchase Request and Response

Create a function that will build and send the BuyVirtualGoodsRequest. We'll be buying the Gold_Coin we created in the previous tutorial. Set the quantity and currency type to 1 and set the Short Code to the name of the item.

The response will help you confirm the item that's been purchased and if any errors occurred:

local function buyVirtualGood()
--Build Request
local requestBuilder = gs.getRequestBuilder()
local buyVirtualGoodRequest = requestBuilder.createBuyVirtualGoodsRequest()

--Set values
--Enter Custom Currency Short Code
buyVirtualGoodRequest:setCurrencyShortCode(CURRENCY_1)
buyVirtualGoodRequest:setQuantity(1)
buyVirtualGoodRequest:setShortCode("Gold_Coin")

--Send Request
buyVirtualGoodRequest:send(function(response)
--Function that returns a table of things bought, we loop through and return ShortCode of virtual goods
 local vGoods = response:getBoughtItems()
 print("Items bought: ")
  for i, vGood in pairs(vGoods) do
   print(vGood:getShortCode())
   end
end)
end

If the player doesn't have the needed funds, the response will come back with a useful error message:

• These messages can be relayed to players to inform them that they need to earn a little more to be able to afford this item.
• For full list of errors please check the API Documentation.

Account Details Request

Now you'll create a function which will retrieve your player's record. For this example, we're going to print the Achievements and Virtual Goods that that player owns.

Create a function that builds the AccountDetailsRequest and sends it:

local function accountInfo()
--Build Request
local requestBuilder = gs.getRequestBuilder()
local accountInfoRequest = requestBuilder.createAccountDetailsRequest()

--Send Request and process response
accountInfoRequest:send(function(response)
--Get achievements table, loop through it, and print the values in it
local achievements = response:getAchievements()
print("Achievements: ")
for i, achievement in pairs(achievements) do
print(achievement)
end
--Get virtual goods table, loop through it, and print the values in it
local vGoods = response:getVirtualGoods()
print("Virtual Goods: ")
for vGood, quantity in pairs(vGoods) do
print(vGood)
end
end)
end
