How can you remove face tracking listener? #218

Open notalentgeek opened 7 years ago

notalentgeek commented 7 years ago

I have this code face_detection.on("track", function (e) { how can I remove or alter the this listener? If I re - add another on("track" listener will that merge or replace the previous one?

Rather than use "on" there is also "addListener(event, handler)" and "removeListener(event, handler)" or "removeAllListeners(optional_event)". If you intend to fire the event only once, that is supported using "once(event_name, handler)". See the EventEmitter class for full details.
