Lua

Other Lua files

extlib/iap_badger.lua and extlib/spinner.lua are used. If you want to change the spinner animation during downloading, please edit the spinner.lua.

model.lua - tmplt/components/store/

please set your host URL of web server to YourHost variable

if model.URL = nil

this means simple IAP store without network download like Kwik3 IAP
downloadBtn, savingTxt won’t be used. You don’t need to create them.

local M = {}
--
local IAP             = require("components.store.IAP")
--
local YourHost  = "http://localhost:8080"
M.URL           = YourHost.."/bookShelf/"
M.backgroundImg = "bg.png"
M.bookShelfType  = {{bookShelfType}} --{pages = 0, embedded = 1, tmplt=2}

How it works

Shelf.psd is internally handled as page01. Let’s show some codes that creates purchase-buttons for Episode2 and Episode3 automatically.

table of pages


1	Shelf.psd	table of contents, user to read an episode or to purchase an episode
2	ep01.psd	Episode1
3	ep02_info.psd	Episode2 Purchase Information
4	ep02_1	Episode2-1
5	ep02_2	Episode2-2
6	ep03	Episode3

page_IAP.lua - componens/page01/

creates instances of displayObject and eventListener of restoreBtn for Episode2 automatically referencing to “restoreBtn” layer
creates instances of displayObjects and eventListeners of purchase/download/savingTxt/savedBtn for Episode2 automatically referencing to “Episode02Icon” layer
creates displayObjects and eventListeners of purchase/download/savingTxt/savedBtn for Episode3 automatically referencing to “Episode03Icon” layer

Episode1 is free and there is no button
the purchase buttons for Episode2 and Episode3 are created

this UI creation also works for page03 of ep02_info.psd that has “Episode02Icon” layer.

CMD.init

Inside CMD.init calls IAP.init to set up the product table from model.lua. For external codes, you may call the following function to check whether a product has been purchased or not.

local IAP = require(“components.store.IAP”)
local productName = “Episode02”
IAP.getInventoryValue(“unlock_”..productName) returns true or false
