Facebook Instant Games extension for the Defold game engine

Facebook Instant Games

Facebook Instant Games extension for the Defold game engine.

Setup

1. Add project dependencies

You can use the extension in your own project by adding this project as a Defold library dependency. Open your game.project file and in the dependencies field under project add:

https://github.com/defold/extension-fbinstant/archive/master.zip

Or point to the ZIP file of a specific release.

2. Preparing index.html

Configure your game.project HTML5 section according to the manual.

2.1 Report loading progress

Facebook Instant Games can show the progress while the game is loaded. It is quite easy to set this up for a Defold game. All that is required is to override the Progress.updateProgress() function and pass along the value to the Instant Games API (this is done for you in the default index.html provided with this extension):

	// Set up a progress listener and feed progress to FBInstant
	Progress.updateProgress = function (percentage, text) {
		FBInstant.setLoadingProgress(percentage);
	}

2.2 Early API initialization

It has been observed that the progress updates do not work properly on Android. The progress stays at 0 and immediately jumps to 100 when the game has finished loaded. This seems to be caused by the Instant Games API not being initialized until after the game has loaded. In order to avoid this it is recommended to initialize the Instant Games API and flag this to the extension (this is done for you in the default index.html provided with this extension):

    // Do early initialization of FBInstant
    // This is required to be able to properly update the loading
    // progress above.
    FBInstant.initializeAsync().then(function() {
        // This will be checked by the FBInstant Defold extension
		Module._fbinstant_inited = true;
	});

3. Create a Facebook App

You also need to create a Facebook App where Instant Games is enabled. Please refer to the Getting Started documentation on the Instant Games page for further instructions.

4. Create a Bundle Configuration file (optional)

You can include an fbapp-config.json configuration file in the application bundle that you publish. The file is put in the root directory of your bundle to specify settings for your application. These settings will apply to all users who the bundle is served to. This enables you to launch different bundles along with different application settings to different audiences. Read more about the format here.

Defold can automatically include this file in the HTML5 bundle using the Bundle Resources setting in game.project. Create a folder in your project to hold the configuration file:

/my_bundle_resources/web/fbapp-config.json

And set my_bundle_resources as the value in the Bundle Resources field in game.project.

Usage

FBInstant API

The extension wraps the Instant Games Javascript API in a Lua interface. The API is designed to wrap version 6.2 of the Instant Games API.

From promises to callbacks

The async API functions are Promise based in Javascript while the Lua counterparts are callback based.

Missing API functions

The Facebook Instant Games platform is still evolving and new APIs are added by Facebook quite frequently. This means that there's likely parts of the API that isn't yet provided by this extension. Refer to the GitHub Issues tagged "Missing API" for a list of know missing APIs.

Facebook Instant Games and LiveUpdate

The LiveUpdate functionality of Defold can be combined with Facebook Instant Games to create really small application bundles where additional content can be downloaded while the player is progressing through game. Combine the excluded content with the application bundle in a single zip file when uploading to the web hosting provided by Facebook Instant Games. When loading the excluded content you're required to load the content from the same base URL as the rest of the game is loaded from. There is a helper module that will get the base URL from the browser:

	local baseurl = require "fbinstant.baseurl"

	local missing_resources = collectionproxy.missing_resources("#level3")
	for _,resource in ipairs(missing_resources) do
		local id = http.request(baseurl.get() .. resource, "GET", callback)
	end

fbinstant.ERROR_USER_INPUT

Tic Tac Toe example

The original Tic Tac Toe example made in Phaser has been recreated in Defold to show how the API is supposed to be user. Refer to the tictactoe folder for the example.

The example has support for two different backends:

1. Activity Store - This stores the game state using the Facebook Instant Games Activity Store API (2018-04-16: activity stores are currently disabled). Change game.gui_script so that it requires tictactoe.game.data.activity_store to use this solution.
2. Node.js server - This stores the game state in a simple Node.js backend and a Postgres database. This is what the official Facebook Instant Games Tic Tac Toe example uses. The server code, created by a Facebook engineer, is located in the tictactoe-server folder. It's quite easy to get the server up an running on Heroku. Change game.gui_script so that it requires tictactoe.game.data.heroku to use this solution.
