Cocos (JavaScript) - Auth

Particle Auth for Cocos

Particle Auth supports Cocos through the Particle Auth Cocos SDK, enabling full integration of Particle’s Wallet-as-a-Service within Cocos-based game applications.

The usage of Particle Auth with Cocos is nearly identical to React Native (JavaScript), with the main differences being in prerequisites and initial setup.

This document will guide you through the setup process. For usage examples, refer to the React Native (JavaScript) documentation.

​

Getting Started

To start the setup process for the Particle Auth Cocos SDK, make sure your project meets the following prerequisites to ensure compatibility:

• Cocos 3.7.2 or higher.
• For iOS:
  • Xcode 15.0 or higher.
  • CocoaPods 1.14.3 or higher.
  • iOS 14 or higher.
• For Android:
  • Minimum API Level 23 or higher.
  • Targets API Level 31 or higher.
  • Java SDK version 11.

Next, you’ll need to retrieve three essential values from the Particle dashboard, which are required across all of Particle’s SDKs: projectId, clientKey, and appId.

​

Installation and configuration

To install and start using the Particle Auth Cocos SDK in your project, follow these steps:

​

Step 1: Copy the Core Assets

1. Locate the Core Assets directory:

   • Navigate to the assets/Mobile/Core directory in the particle-cocos repository.

2. Copy the Core Assets directory:

   • Copy the entire Core folder to your project’s assets directory.

​

Step 2: Copy the Native Engine Files

1. Locate the Native Engine directory:

   • Navigate to the native/engine directory in the particle-cocos repository.

2. Copy the Native Engine directory:

   • Copy the entire engine directory to your project’s native directory.

​

Android

If you’re using Cocos on Android, the configuration is quite simple and purely requires the placement of the previously retrieved values (projectId, clientKey, and appId) within $exportDir/proj/gradle.properties, such as within the example below.

android.enableJetifier=true

PN_PROJECT_ID = YOUR_PROJECT_ID

PN_PROJECT_CLIENT_KEY = YOUR_CLIENT_KEY

PN_APP_ID = YOUR_APP_ID

​

iOS

If you use iOS, the initial configuration will be more complicated. To begin, ensure you have a Podfile.

If you don’t have one already, head over to the root of your Xcode project directory and run:

pod init

Head into this newly generated (or existing) Podfile and remove all existing contents, then paste the configuration included below.

Alternatively, if you’re already using other SDKs through CocoaPods, you can include the Particle Auth SDK declaration:

ENV['SWIFT_VERSION'] = '5'
platform :ios, '14.0'
source 'https://github.com/CocoaPods/Specs.git'

target 'boost_container' do
  use_frameworks!
end

target 'cocos_engine' do
  use_frameworks!
end

target 'ParticleCocosDemo-mobile' do
  use_frameworks!
  pod 'ParticleAuthService'
  pod 'ParticleNetworkBase'

end

post_install do |installer|
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
    config.build_settings['BUILD_LIBRARY_FOR_DISTRIBUTION'] = 'YES'
      end
    end
end

Additionally, you can run pod install --repo-update, then open {your project}.xcworkspace to update and see your project within Xcode.

Now that you’ve configured your Particle dashboard, installed the SDK, and configured a Podfile, it’s time to initialize the SDK with the aforementioned projectId, clientKey, and appId retrieved from the Particle dashboard.

1. Create a ParticleNetwork-Info.plist file from the root of your corresponding Xcode project.

2. Paste the following text into this file:

   ParticleNetwork-Info.plist

   <?xml version="1.0" encoding="UTF-8"?>
   <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
   <plist version="1.0">
   <dict>
   	<key>PROJECT_UUID</key>
   	<string>YOUR_PROJECT_UUID</string>
   	<key>PROJECT_CLIENT_KEY</key>
   	<string>YOUR_PROJECT_CLIENT_KEY</string>
   	<key>PROJECT_APP_UUID</key>
   	<string>YOUR_PROJECT_APP_UUID</string>
   </dict>
   </plist>
   

3. Replace the placeholders with the values retrieved from your project and application within the Particle dashboard.

4. Drop the following files into your project and set the target at the main app. Make sure Base58.swift, Model.swift, and ParticleAuthPlugin.swift are marked within TargetMembership.

   If Xcode asks to make a Swift bridging file, select Yes.

5. Open your AppDelegate file and include a custom return within the (BOOL)application:openURL:options: method, as shown in the example below:

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url options:(NSDictionary<UIApplicationOpenURLOptionsKey,id> *)options {
    return [ParticleAuthSchemeManager handleUrl:url];
}

6. Within AppDelegate, ensure a project-specific import is included at the top of the file. This should be #import "{project name}-Swift.h".

7. Finally, to configure your app scheme URL, select your app from “TARGETS” within the “Info” section, click the plus icon to add the URL types, and paste your scheme in “URL Schemes.”

​

Usage

Using the Particle Auth Cocos SDK is identical to the examples provided in the React Native (JavaScript) documentation.

The only difference is the import statement, which should include the internal path ../../Core/particleAuth, as shown below:

import * as particleAuth from "../../Core/particleAuth";
