Events

In a Music Pack, Events are one-shot music that is played when some in-game event occurs, for example the player getting an advancement, or waking up from a bed. When an event plays, any ongoing music will quiet down until the event music finishes.

The Event Pool

Events are tied to predicate nodes, in that each predicate node contains a list of events. When that predicate node is chosen, the event pool (the list of events that are able to be triggered) is updated. The current event pool is always the aggregate of the current predicate node's events and those of it's ancestors all the way up to root. If there is a conflict between two events between parent and child, the child will always take priority.
