Help identifying each product for In - App Purchase

Games
#1

Hey community. Ok 'm facing this problem were I want to have a product in the IAP be identified. To make it clear I used the Lemonade Example code below

[code]local ui = require(“ui”)
local store = require(“store”) – Available in Corona build #261 or later

local isSimulator = “simulator” == system.getInfo(“environment”)

display.setStatusBar( display.HiddenStatusBar )

local hi = 0
local hig = display.newText(“h”, 30, 30,“Arial”, 30)

– Unbuffer console output for debugging
io.output():setvbuf(‘no’) – Remove me for production code

local titlecard
function showTitle()
if isSimulator then
local myAlert = native.showAlert( “iTunes Store not available in Corona Simulator”,
“Offline testing: see console for output.”,
{ “OK” } )
end
titlecard = display.newImage( “titlecard.png”, true )
titlecard.x = display.contentCenterX
titlecard.y = display.contentCenterY
end

local bg
local validProducts, invalidProducts = {}, {}
local descriptionArea

– Product IDs should match the In App Purchase products set up in iTunes Connect.
– We cannot get them from the iTunes store so here they are hard coded;
– your app could obtain them dynamically from your server.

local listOfProducts =
{
– These Product IDs must already be set up in your store
– We’ll use this list to retrieve prices etc. for each item
– Note, this simple test only has room for about 4 items, please adjust accordingly

– The iTunes store will not validate bad Product IDs

}

– Process and display product information obtained from store.
– Constructs a button for each item

– Purchase the item
if store.canMakePurchases then
store.purchase( {product} )
else
native.showAlert(“Store purchases are not available, please try again later”,
{ “OK” } )
end
end
function buyThis_closure ( index )
– Closure wrapper for buyThis() to remember which button
return function ( event )
buyThis (validProducts[index].productIdentifier)

return true
end
end
local hideDescription = function ( )
descriptionArea.text = “Select a product…”
end
local describeThis = function ( description )
– Display product description for testing
print (“About this product: " …description)
– TODO wrap if necessary
descriptionArea.text = description
timer.performWithDelay( 2000, hideDescription)
end
function describeThis_closure ( index )
– Closure wrapper for describeThis() to remember which button
return function ( event )
describeThis (validProducts[index].description)
return true
end
end
local formatted = string.format(”%.2f", validProducts[index].price)
local label = validProducts[index].title … " " …formatted
local myButton = ui.newButton{
default = buttonDefault, over = buttonOver,
onPress = describeThis_closure (index), onRelease = buyThis_closure (index),
text = “”, textColor = {2, 0, 127, 255}, font=“Marker Felt”, size = 14, emboss = false
}
myButton:setReferencePoint(display.CenterLeftReferencePoint)
myButton:setText(label)
return myButton
end

– Utility to build a restore button
function newRestoreButton ()
local buttonDefault = “buttonRestore.png”
local buttonOver = “buttonRestoreDown.png”
local restore = function ( product )

store.restore()
end

end

– Main

– Show title card
showTitle ()

– Connect to store at startup
store.init (transactionCallback )
print (“After init”)

– Hide title card, run store
timer.performWithDelay (1000, setupMyStore) [/code]

Now my problem with the above is I want to have this code be put

saveFile("twinb.txt", 2) saveFile("twinb.txt", 3)

I want those two different code to be put on seperate IAP so example the saveFile("twinb.txt", 2) cost $0.99 in the IAP and the saveFile("twinb.txt", 3) cost $1.99 how do I do it like that letting the person know there buying two different things.

Have one button for each and a variables.

eg;

local toPurchase

when user clicks button to but 0.99 item set toPurchase = itemName, same thing for 1.99.

Then if transaction is successful then if toPurchase == X then do Y. (In this case save to specific file depending on what was bought.) [import]uid: 52491 topic_id: 22165 reply_id: 88348[/import]

#3

@peach I’m still confuse with the explanation you gave may I get further explanation [import]uid: 17058 topic_id: 22165 reply_id: 88397[/import]

#4

@peach just to make it easier my explanation is I don’t know how to set variable buttons ONLY for IAP. For other stuff yes. But I struggle with settings variables for IAP it seems confusing. [import]uid: 17058 topic_id: 22165 reply_id: 88398[/import]

#5

@peach in the code I posted in the is ok I do this in between lines 68 - 70 this

[code] return function ( event )

buyThis (validProducts[index].productIdentifier)
saveFile(“twinb.txt”, 2)
return true[/code]

I tried and it works is it ok that I do that instead for my In App Purchase [import]uid: 17058 topic_id: 22165 reply_id: 88570[/import]

#6

It is the same as setting buttons for anything else - I would like to help you further but I’m really struggling to work out how to explain this beyond what I’ve said above.

The lemonade example does show you how to purchase different products, I think you really need to focus on learning about that and understanding it before trying to implement the logic into your own project. [import]uid: 52491 topic_id: 22165 reply_id: 88571[/import]

#7

@peach I did is just I can’t figure out how to give these

saveFile("twinb.txt", 2) saveFile("twinb.txt", 3)

To there own table button.

In Post #4 I did above is that right would apple approve my In App Purchase if I did it like that? [import]uid: 17058 topic_id: 22165 reply_id: 88573[/import]

#8

Those things don’t need a table.

If it works Apple will approve it - they don’t look at your code.

To save you’d do;

if myVariable == 1 then
–save for 1st purchase here
elseif my Variable == 2 then
–save for 2nd purchase here
end
end

Basically, that. [import]uid: 52491 topic_id: 22165 reply_id: 88608[/import]

#9

@peach the variable code you gave me this

if myVariable == 1 then --save for 1st purchase here elseif my Variable == 2 then --save for 2nd purchase here end end

Were does that go in lemonade example because for them to buy item 1 or to I have to do this myVariable = 1 when by that item 1 or myVariable = 2 item 2. So actually were does myVariable = 1, and myVariable = 2 go in the lemonade example? [import]uid: 17058 topic_id: 22165 reply_id: 88655[/import]

#10

You don’t need it with that code. Line 214 when event is successful you should be able to get product ID. What is infoString printing? [import]uid: 52491 topic_id: 22165 reply_id: 88789[/import]

#11

@peach so what are you trying to say? [import]uid: 17058 topic_id: 22165 reply_id: 88798[/import]

#12

… “What is infoString printing?”

^ That. [import]uid: 52491 topic_id: 22165 reply_id: 88830[/import]
