This node is used to receive events triggered by an Event Sender node. A great place to learn more about events is in the event tutorial.
This port can be used to disable the event receiver node. If set to No the receiver node will not be activated when the corresponding Event Sender node is triggered.
Each Event Receiver node must listen to a specific channel. This means that when an Event Sender node of that channel is triggered all Event Receiver nodes with the same channel will be triggered as well.
The Event Receiver node will automatically get outputs from all Event Sender nodes connected to the same channel. See the Event Sender documentation for more details on adding ports for sending values with events.
This is a signal port, it is triggered when a signal is triggered in any Event Sender node with the same channel as this Event Receiver node.
