Facebook Instant Games
Starting with Cocos Creator v1.9, creating games for the Facebook Instant Games platform is officially supported. Developers can quickly publish games that meet the Facebook Instant Games technical standards. Facebook Instant Games are a bit different compared to WeChat Mini Games and QQ Play, as Facebook Instant Games runs in a pure HTML5 environment. This means that your games can be run not only on your phone but also in a desktop browser, making development and debugging more convenient.
Cocos Creator includes:
- Integrated Facebook Instant Games SDK, and automatic initialization, users can directly call the relevant API
- Provides a one-click packaging process in the Cocos Creator Build Panel that can be packaged directly into a Facebook Instant Games that meets all technical specifications
What the user needs to do:
- Call the Facebook Instant Games SDK to access platform-related features
- Upload your Cocos Creator packaged version to Facebook according to the Facebook Release process
- Build your game using Cocos Creator
- Test your game
- Upload your game to Facebook background
- Share your game on Facebook
First, use Cocos Creator to build the game
Using Creator open the project project that needs to be published. Open the Build Publish panel from the Menu bar. Select
Project and select the Facebook Instant Games platform in the build Publish panel:
After the build is complete, a
fb-instant-games folder will be created in the specified directory:
Second, test the game
Create a new application in the background of Facebook, add an Instant Games in Add a Product, set the game category, and save the changes. (For details, please refer to the setting application)
Enable the https-enabled Web server locally
Install http-server package via npm
npm install -g http-server
Create the private key and certificate through openssl. The path needs to be assigned to the built
cd fb-instant-games/ openssl genrsa 2048 > key.pem openssl req -x509 -days 1000 -new -key key.pem -out cert.pem
Once the private key and certificate are ready, the Web service can be started locally via SSL.
http-server --ssl -c-1 -p 8080 -a 127.0.0.1
Use the browser to open https://localhost:8080 and skip the security warning displayed by the browser. This step is only to allow the browser to whitelist the above private key and certificate. If you subsequently regenerate the private key and certificate, you will need to turn on the confirmation again. It is not yet possible to preview the game directly at this step, because the preview game needs to initialize the Facebook Instant Games SDK. You need to use the following method.
Preview the game on Facebook

https://www.facebook.com/embed/instantgames/YOUR_GAME_ID/player?game_url=https://localhost:8080 in your browser. Pay attention to the
YOUR_GAME_ID in the link. Replace the application number you created in Facebook.
Then you can see the game running successfully:
