#defold #iap In-App Purchases Walkthrough with Google Play Store

As promised, here is the walkthrough for getting In-App purchases set up for the Google Play Store.

PLEASE NOTE - On my test android phone, the 5 Gems product did work like the previous demo video.

HERE IS THE GUI_SCRIPT FROM THE VIDEO FOR COPYING AND PASTING MINUS THE COMMENTED LINES:
local GEMS_SM = "com.ia.purchases.gem.small"
local GEMS_MD = "com.ia.purchases.gem.medium"
local GEMS_LG = "com.ia.purchases.gem.large"

local function iap_listener(self, transaction, message_id, message, error)
if error == nil then
if transaction.state == iap.TRANS_STATE_PURCHASED then
iap.finish(transaction)
if transaction.ident == GEMS_SM then
msg.post(".", "gems_small")
elseif transaction.ident == GEMS_MD then
msg.post(".", "gems_medium")
elseif transaction.ident == GEMS_LG then
msg.post(".", "gems_large")
end
end
else
gui.set_text(gui.get_node("text"), error.error)
end
end

function init(self)
msg.post(".", "acquire_input_focus")

iap.set_listener(iap_listener)
self.gems = 0
end

function on_message(self, message_id, message, sender)
if message_id == hash("update_gems_small") then
iap.buy(GEMS_SM)
elseif message_id == hash("update_gems_medium") then
iap.buy(GEMS_MD)
elseif message_id == hash("update_gems_large") then
iap.buy(GEMS_LG)
end

if message_id == hash("gems_small") then
self.gems = self.gems + 5
elseif message_id == hash("gems_medium") then
self.gems = self.gems + 50
elseif message_id == hash("gems_large") then
self.gems = self.gems + 500
end
gui.set_text(gui.get_node("gem_inv"), self.gems)
end

function on_input(self, action_id, action)
if action_id == hash("touch") and action.pressed then
if gui.pick_node(gui.get_node("gems_small"), action.x, action.y) then
gui.set_enabled(gui.get_node("answer"), true)
elseif gui.pick_node(gui.get_node("gems_medium"), action.x, action.y) then
gui.set_enabled(gui.get_node("answer1"), true)
elseif gui.pick_node(gui.get_node("gems_large"), action.x, action.y) then
gui.set_enabled(gui.get_node("answer2"), true)

elseif gui.pick_node(gui.get_node("com.ia.purchases.gem.small"), action.x, action.y) then
gui.set_enabled(gui.get_node("answer"), false)
self.purchase = true
gui.set_text(gui.get_node("text"), "small gems bought")

if self.purchase == true then
msg.post(".", "update_gems_small")
end

elseif gui.pick_node(gui.get_node("com.ia.purchases.gem.medium"), action.x, action.y) then
gui.set_enabled(gui.get_node("answer1"), false)
self.purchase = true
gui.set_text(gui.get_node("text"), "medium gems bought")

if self.purchase == true then
msg.post(".", "update_gems_medium")
end

elseif gui.pick_node(gui.get_node("com.ia.purchases.gem.large"), action.x, action.y) then
gui.set_enabled(gui.get_node("answer2"), false)
self.purchase = true
gui.set_text(gui.get_node("text"), "large genm bought")

if self.purchase == true then
msg.post(".", "update_gems_large")
end

elseif gui.pick_node(gui.get_node("no"), action.x, action.y) then
gui.set_enabled(gui.get_node("answer"), false)
gui.set_text(gui.get_node("text"), "THANKS FOR CONSIDERING.")
elseif gui.pick_node(gui.get_node("no1"), action.x, action.y) then
gui.set_enabled(gui.get_node("answer1"), false)
print("NO")
gui.set_text(gui.get_node("text"), "THANKS FOR CONSIDERING.")
elseif gui.pick_node(gui.get_node("no2"), action.x, action.y) then
gui.set_enabled(gui.get_node("answer2"), false)
print("NO")
gui.set_text(gui.get_node("text"), "THANKS FOR CONSIDERING.")

elseif gui.pick_node(gui.get_node("power"), action.x, action.y) then
os.exit()
end
end
end
