Before you start

Estimated time of SDK implementation: 10 minutes. Please, follow the guide carefully, it will save you from many future problems.

1. SDK configuration

Before a possibility to connect to the SDK, there is need to make a project configuration.

1.1. Create a project

Create new html5 game project in projects section of GameArter system.

This is way you will get your project Id for communication with GameArter SDK.

1.2. Project configuration

Create a configuration for selected project version. You can have up to 5 versions of every project. (Only 1 version can be live, the other 4 serves for development purposes or AB testing).

  1. Open Menu → View → Addon Manager
  2. Press "Install new addon..." button
  3. Select downloaded GameArter's addon
  4. Relaunch / Reload Construct 3

Construct 2

  1. Unzip downloaded GameArter package for Construct
  2. Copy folder "gamearter" to "exporters\html5\plugins" folder of Construct 2. Usually "C:\Program Files\Construct 2\exporters\html5\plugins"
  3. Launch Construct
  4. Insert GameArter (available in "Platform specific") to requested project by "Insert new Object" option. (available after right mous button click in Layout tab.

Insert GameArter SDK into your project:

  1. Press right mouse button in Layout scene
  2. Select "Insert new object option"
  3. In "Platform Specific section", find and select GameArter SDK. Note, you will find this SDK there only if you do not have it selected in your project yet and you have it added in Construct.

2.3. Fixing possible errors

  • Error on load on GameArter domain. Be sure you did not select minify option during game export. Minification made by construct is not compatible with external scripts. Use available tools for post-export minification and obfuscation.
  • Any issue found or need a help? Let me know. GameArter Slack: @adm_vladimir / email - [email protected] /

3. Working with SDK

3.1. SDK initialization

GameArter SDK is initialized automatically. Initialization is created on basis of configuration data filled in GameArter object.

3.4 GameArter object Expressions

Category Action Description
TECH BrowserName Returns browser name. List of Browsers
IndividualGameMode Returns game mode set for current domain.
USER UserCountry Returns user country code. List of countries
UserLang Returns user language code. List of languages
UserNick Returns User nick
UserRankName Returns user rank name
Closer explanation
  • Individual Game Mode

    There's a possibility you require to run the game in individual game mode on certain website or e.g. for testing. By using individual game mode features, you can set individual mode the game will run in for every website the game is published on. SDK will return you after its initialization number of mode which you will assign to a certain website. Then, you can simply set data with which the game should run according the mode number.

  • Browser name

    WebGL games have often different performance in various browsers. With knowledge of a browser a game is running in, there is a possibility for optimization of disabling features for certain browsers. E.g. car destructions for Chrome.

4 Examples

4.1 Sdk Initialization

Requests to GameArter SDK may be caled only after SDK initialization.

4.2 Get user info

Asking for nick-names is very annoying. Instead, nickname should be took from user's profile in GameArter. Similar with language, country and so on. Users should not be requested for any data they already provide. Here's example of available expressions for getting user's nickname, country and language.

gamearter sdk for Construct - Get user info

4.3 Ads

Available ad types
  • Fullscreen midroll ads (= Interstitial ads)
  • Rewarded ads (= Fullscreen ads with a reward for watching)

Ad types can be combined in a game (One game can use both types of ads)

Fullscreen ad

Ad rules
  • Call ads only in suitable places. Ads cannot affect best user experience (UX) from playing games
  • Call ads in any suitable place for ad
  • Game sounds MUST be muted during an ad
  • Any exhortation or rewards for interacting with ads is prohibited
What is happening after an ad call:
  1. ad request is received in GameArter Ads manager.
  2. GameArter Ads manager checks availability of ads and processes ad-frequency-check.
  3. Ad state is returned by callback function.

Callback states

  • loaded = (OnPauseGame) → Midroll ad has been loaded. Game sounts must be muted
  • success = (OnResumeGame) Midroll ad has been succesfully completed. unmute sounds
Example implementation:
gamearter sdk for Construct - Ads
An alternative implementation through script code

Note: We are dealing with an issue in the Construct v350 where an event associated with ad callback state OnPauseGame and OnResumeGame is not being triggered. This is an alternative solution that works for muting and unmuting game sounds during ads.

function callInter(runtime){
			case "loaded":
				// mute game
				runtime.globalVars.isSilent=1; // example through global variable
			case "completed":
				// unmute game

Rewarded ad

Availability of a rewarded ad is individual based on user's behaviour. Display button / option to launch rewarded ad only if the rewarded ad is available.

Callback states

  • loaded = (OnPauseGame) → Rewarded ad has been loaded. Game sounts must be muted
  • success = (OnRewardedAdSuccess) Rewarded ad has been succesfully completed. Release reward + unmute sounds
  • failed = (OnRewardedAdFailed) something went wrong - user canceled the ad unmute sounds without reward

Button / UI for requesting rewarded ad must be visible only if rewarded ad is available (condition "Is Rewarded ad Available")

Example implementation:
gamearter sdk for Construct - Rewarded Ads
Alternative implementation through script code

Note: We are dealing with an issue in the Construct v350 where an event associated with ad callback state OnPauseGame and OnResumeGame is not being triggered. This is an alternative solution that works for muting and unmuting game sounds during ads.

function callReward(runtime){
	var sound= runtime.globalVars.isSilent;
	// On rewarded ad request from user (e.g. pressing rewarded ad button)
			case "loaded":
				// mute game
				runtime.globalVars.isSilent=1; // example through global variable
			case "completed":
				// release reward
				// unmute game
			case "failed":
				// unmute game

4.4 Analytics

You can use any tool for tracking you want. Do not you know any? Here's example of few of them.

By default, GameArter has implemented and supports Google Analytics for websites with a bridge of caching game-side data events. All you need to do to activate it, is to insert your own Google Analytics tracking id to "Basic settings" tab of your project. This analytics tracks all gameplayer-based data as players, source of visits, time of playing and so on. These data can be extended by data in a form of events sent from a game, see Google analytics guide page. Some basic events as scene change and so on can be send to analytics automatically on basis of analytics configuration.

gamearter sdk for Construct - Analytics

For more info related analytics events, see Google Analytics Events documentation.

4.5 Fullscreen

Because of other services around a game, fullscreen mode must be called over GameArterSDK. Attach following call to fullscreen button in your game (if your game has such button). If a game is already in fullscreen mode, fullscreen is cancelled by the call.

4.6 Redirects

  • Tracking redirects

    With our solution you will know about every made redirect. - From what logo, on what website, and how oftenly is being used.

4.7 Cutscenes module

Every game contains many data-weight cutscenes, stories and animations which are displayed calmly only one time for the whole game. GSDK helps to reduce game filesizes by providing a story module — an option for downloading these stories from external storage only in a time when it’s required. Dynamic loading of game stories might be done via asset bundles or this SDK feature when the story is displayed in gameplayer above the game (like an ad).

  • 1) Calling browser stories

    Be sure that animation of such number is available for your game.

  • 2) Callback functions

    There is a callback state - "not found","loaded", progress states and "completed".

    gamearter sdk for Construct - Cutscene
  • 3) Setting / switching of stories

    Is being made in "More" section of configuration of the project

4.8 Game as App

GameArter SDK allows to installation of web games as Web Apps to user's device. Installation is possible to PC as well as mobile device. This feature is available for games running directly at GameArter (not within an iframe).

GameArter - install games as apps
  • NOTE: this feature is functional after submiting requests for publishing in GameArter.
  • Icon of web app (displayed at user's screen of desktop / mobile) must be in .png format and in 2 dimensions - 192x192 & 512x512px. Name them "favicon-192.png" and "favicon-512.png" and attach to folder "_pwa". Upload this folder with other project files in "Files upload" section at GameArter panel.
