EventEmitter object. Used to subscribe to all events emitted from the SDK. These events include onEntityCreated, onEntitiesUpdated, onFramePostRender, and more. You can register and deregister callbacks to events with on and off.
Example
function onEntityCreated(createdEntity)
{
console.log(createdEntity.getName(), 'was created!');
}
// Register callback
SDK3DVerse.notifier.on('onEntityCreated', onEntityCreated);
// Unregister callback
SDK3DVerse.notifier.off('onEntityCreated', onEntityCreated);Methods
off(eventName, callback) → {EventEmitter}
