System event

System event is a notification from WaveVR to let a developer capture runtime behavior or status change. A developer can add an actor component to monitor a specific event from WaveVR and do actions after the event is received.

A developer can listen to ALL system events in Blueprint like:

In order to listen an event, a developer should add the component WaveVREventCommon and bind the event to OnAllEventBp.

The target name of Event is free, here named Event_All.
