Listening once on array about eventemitter2 HOT 4 CLOSED

According to the README, this line

   game.once(['player:quit', 'player:disconnect'], function () { endGame() });

would be interpreted by EE2 as a listen on ONE event with the name player:quit.player:disconnect

which is why it doesn't meet your expectations. Seems to me that EE2 is working as documented.

@gotwarlost That's why this is a feature request so that it works with array of events.

im not sure, why not just do this...

game.once('player:quit', function () { endGame() });
game.once('player:disconnect', function () { endGame() });

the only reason i say it might not be a good idea, is because its a huge performance sacrifice to add this feature.

@hij1nx I think something like onceOneOf(['x:event1', 'x:event2'], callback) like this sample:

var clean = function() {
  game.removeListener('player:quit', clean);
  game.removeListener('player:disconnect', clean);
  // …
  endGame();
}

game.on('player:quit', function () { endGame() });
game.on('player:disconnect', function () { endGame() });

Can be simlified:

game.onceOneOf(['player:quit', 'player:disconnect'], function () { endGame() });
