#disconnected(attributes = {}) {|event| ... } ⇒ DisconnectEventHandler

This event is raised when the bot has disconnected from the WebSocket, due to the Bot#stop method or external causes. It's the recommended way to do clean-up tasks.

    Event attributes, none in this particular case

Yields:

  • The block is executed when the event is raised.

Yield Parameters:

end

#heartbeat(attributes = {}) {|event| ... } ⇒ HeartbeatEventHandler

This event is raised every time the bot sends a heartbeat over the galaxy. This happens roughly every 40 seconds, but may happen at a lower rate should Discord change their interval. It may also happen more quickly for periods of time, especially for unstable connections, since discordrb rather sends a heartbeat than not if there's a choice. (You shouldn't rely on all this to be accurately timed.)

All this makes this event useful to periodically trigger something, like doing some API request every hour, setting some kind of uptime variable or whatever else. The only limit is yourself.

Parameters:

  • attributes (Hash) (defaults to: {})

    Event attributes, none in this particular case

Yields:

  • The block is executed when the event is raised.

Yield Parameters:

Returns:
