UAvaPlayableGroup

This class defines the interface and base of a playable group.

API > API/Plugins > API/Plugins/AvalancheMedia

This class defines the interface and base of a playable group.

A playable group is intended to group playables according to the underlying rendering implementation. In most cases, it corresponds to a game instance, either owned or not, local to the process or remote.

It tracks and manage the playables state, transitions and visibility constraints.

The design goal of this class is to allow hooking the playable framework to any game instance, including PIE so it can work with any work flow (editor, PIE, game, nDisplay, etc).

Ideally, the playable class itself should be "game instance" agnostic and do all it's bidding on it's container through this class.
