overwolf.extensions.current API

Notify you when something interesting happens while playing a particular game.

The full list of supported games with their Game ID’s is always up to date and can be found here.

Please read all the info about how to use game events in your app in our using game events guide.

The difference between overwolf.games.events to overwolf.games

This API enables you to get real-time game events (kill, death, etc.) for specific games that are defined in your app's manifest, under the "game_events" section.

Regardless, you have the overwolf.games API that gives you general "game info" events about the currently running game's state (process name, focus, command line info, and more).

Sample App​

You can find an example of overwolf.games.events API usage here. This one notifies whenever a relevant event has happened in League of Legends.

setRequiredFeatures(features, callback)​

Version added: 0.93​

Sets the required features from the provider.

ParameterTypeDescription
featuresstring[]String array of features to utilize
callback(Result:SetRequiredFeaturesResult) => voidall available features for the registered games declared in the manifest

Usage Example​

Example for setting League of Legends required features:

var g_interestedInFeatures = [
  'summoner_info',
  'gameMode',
  'teams',
  'matchState',
  'kill'
];

overwolf.games.events.setRequiredFeatures(g_interestedInFeatures, function(info) {
    if (info.success == false)
    {
      console.log("Could not set required features: " + info.error);
      return;
    }
}
note
  1. it's important to wait for the success status to ensure that required features will be registered and trigger events properly.
  2. If your app uses a background controller, make sure to call the setRequiredFeatures function only from your background controller.

Example for setting required features and waiting for 'success':

  async setRequiredFeatures() {
    let tries = 1;
    let result;

    while ( tries <= MAX_RETRIES ) {
      result = await new Promise(resolve => {
        overwolf.games.events.setRequiredFeatures(FEATURES_ARRAY, resolve);
      })

      if ( result.success === true ) {
        // make sure our required features were registered
        return (result.supportedFeatures.length > 0);
      }

      // wait 3 sec before retry
      await new Promise(resolve => {
        setTimeout(resolve, 3000);
      });
      tries++;
    }

    console.warn('setRequiredFeatures(): failure after '+ tries +' tries'+ JSON.stringify(result, null, 2));
    return false;
  }

getInfo(callback)​

Version added: 0.95​

Gets the current game info.

ParameterTypeDescription
callback(Result:GetInfoResult) => voidProvides the current game info

Usage Example​

overwolf.games.events.getInfo(function(info) {
   console.log(info);
});

onError​

Version added: 0.78​

Fired when an error occurred in the Game Event system, with the following structure: ErrorEvent Object.

onInfoUpdates2​

Version added: 0.96​

Fired when there are game info updates with a JSON object of the updates, in the following structure: InfoUpdates2Event Object

Our best practice is removing event listeners and then adding the listener back to prevent accidental multiple listeners.

Usage Example​

overwolf.games.events.onInfoUpdates2.addListener(function(info) {
      console.log("Info UPDATE: " + JSON.stringify(info));
});

onNewEvents​

Version added: 0.96​

Fired when there are new game events with a JSON object of events information, in the following structure: NewGameEvents Object

Our best practice is removing event listeners and then adding the listener back to prevent accidental multiple listeners.

Usage Example​

overwolf.games.events.onNewEvents.addListener(function(info) {
   console.log('EVENT FIRED: ' + JSON.stringify(info));
});
