Below is a technical guide to integrating this functionality:<\/p>\n<h3>Step 1: Setup Store Services<\/h3>\n<ul>\n<li><strong>iOS with StoreKit:<\/strong> Utilize StoreKit for managing in-app purchases. Ensure you include the required StoreKit framework in your project settings.<\/li>\n<li><strong>Android with Google Play:<\/strong> Set up Google Play Billing, ensuring your app is configured with the necessary permissions and services in your Android manifest.<\/li>\n<\/ul>\n<h3>Step 2: Create the Restore Callback<\/h3>\n<p>With the purchase systems initialized, you\u2019ll need a callback function to handle requests to restore previous transactions. This function will vary slightly between iOS and Android:<\/p><div style=\"clear: both; margin: 20px 0;\"><h4 style=\"color: #4D54FBCE; margin-bottom: 10px;\">Play free games on Playgama.com<\/h4><div id=\"widget-playgama\" style=\"height: 237px;\"><\/div><\/div>\n<pre><code>-- Example wrapper to request restoration eequests \nfunction restore_purchases()\n  if system.get_sys_info().system_name == \"iOS\" then\n    -- Call restore function for iOS\n    lua_bridge.call(\"restorePurchases\")\n  elseif system.get_sys_info().system_name == \"Android\" then\n    -- Call restore function for Android\n    lua_bridge.call(\"restoreTransactions\")\n  end\nend<\/code><\/pre>\n<h3>Step 3: Handle Purchase Restorations<\/h3>\n<p>When the restore request is fulfilled, implement logic to handle the successful retrieval of previous purchases.<\/p>\n<pre><code>function handle_restore_response(payment_data)\n  for _, product in pairs(payment_data) do\n    -- Check each product and restore it accordingly\n    if product.state == \"restored\" then\n      manage_restored_purchase(product)\n    end\n  end\nend<\/code><\/pre>\n<h3>Step 4: User Interface for Restore<\/h3>\n<p>Provide users with the ability to restore purchases through a button in your game\u2019s UI.<\/p>\n<pre><code>gui.pick_node(self.restore_button_node, action.x, action.y)<\/code><\/pre>\n<p>Ensure your UI clearly communicates the purpose of the restore function.<\/p>\n<h3>Step 5: Testing<\/h3>\n<p>Finally, it is crucial to test the restore functionality thoroughly on both iOS and Android platforms. Use sandbox environments and real device testing to confirm that the process aligns with platform guidelines and executes without errors.<\/p>\n<h3>Considerations<\/h3>\n<ul>\n<li>Maintain user data across sessions and restorations to ensure a seamless user experience.<\/li>\n<li>Adhere to both Apple\u2019s and Google\u2019s best practices and precisely follow the StoreKit and Google Play Billing documentation.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>Implementing \u2018Restore Purchase\u2019 in Defold To implement a \u2018restore purchase\u2019 feature in your mobile game using Defold, particularly for iOS and Android, you need to follow several key steps.
